What are the main equipment parts of lng gasification station

Cryogenic storage tank, vaporizer, electric auxiliary heating, voltage regulation metering

The cryogenic storage tank is called a vertical or horizontal double-layer vacuum insulation tank, the inner tank is made of austenitic stainless steel, and the outer container material is 345R according to different user areas. the inner and outer containers are interlayer filled with thermal insulation material pearlite sand and vacuum, and the product is inspected on site by the State Bureau of Technical Supervision and issued a pressure vessel supervision certificate.

Air temperature carburetor

The air-temperature vaporizer series uses the natural convection air in the atmospheric environment as the heat source, extrudes the aluminum with good thermal conductivity into a star-shaped fin tube to heat exchange with the cryogenic liquid and gasifies into a certain temperature gas without additional power and energy consumption. All the equipment are static parts, so its performance is quite stable and maintenance is simple, so it is a new generation of heat exchanger with high efficiency, environmental protection and energy saving.

Summary of performance characteristics and uses of water bath vaporizer:

The water bath gasifier uses the hot water in the shell side to heat and gasify the low temperature gas immersed in the internal winding pipe to make its outlet gas temperature meet the needs of users.

It is a kind of equipment that gasifies the low-temperature liquid gas into gaseous gas through the heat exchange between hot water and low-temperature liquid gas. It is suitable for liquid oxygen, liquid nitrogen, liquid argon, liquid carbon dioxide, liquefied petroleum gas, liquefied natural gas and so on.

The circulating hot water bath carburetor directly uses circulating hot water to heat the liquid gas in the coil and gasify it into gaseous gas. For large enterprises and institutions, under the condition of sufficient hot water, steam or electricity, the use of water bath carburetor can fully ensure the heat transfer efficiency, and has many advantages, such as compact structure, small area, low price and so on.

Pressure regulating metering pry

Safety is the top priority of the LNG surge sled design. In the core equipment of the surge sled, the most important is the safety cut-off valve, also known as the emergency safety cut-off valve. It is installed in the upstream of the voltage regulator and is located at the entrance of the LNG surge sled. In case of emergency, after a series of safety measures such as the release of the safety valve and monitoring the action of the voltage regulator, the downstream gas is still overpressured. The safety equipment of the upstream gas is cut off by turning off quickly. It is the last safety barrier to protect the safety of the whole station and avoid downstream overpressure or even explosion caused by voltage regulator failure. Therefore, it must be sensitive, cut off quickly, high reliability and strong ability to resist external interference.

What is the main machinery of the container port

Port handling machinery can be divided into three basic types: lifting machinery, conveying machinery and handling machinery. At present, there are more than 100 kinds of loading and unloading machinery used in the port, of which about 30 are widely used.

1. Lifting appliances.

A machine that can lift goods vertically and move horizontally. Its work is characterized by intermittent repetition, and there is no-load time in each work cycle. Lifting appliances are mainly all kinds of lifting equipment, such as portal crane, portal grab ship unloader, bridge grab ship unloader, gantry crane and floating crane (see lifting ship) and so on. Container terminals mainly use quayside container cranes.

Portal crane.

A kind of rotary jib crane, which gets its name because of its gate-shaped base (door base), also known as door crane and door crane. It has four coordinated working mechanisms: lifting, rotating, luffing and walking (figure 1). The portal crane runs along the ground track. Railway vehicles and cars can be passed under the door seat. The crane has the advantages of long jib frame, large lifting height, fast working speed of each mechanism, large working range, high productivity, and can be equipped with different pick-up devices. For example, hooks can load and unload heavy parts such as goods and steel, grab can load and unload bulk cargo, and special hoists can load and unload containers (but not as efficient as container special equipment), so it is universal. China produces portal cranes with different lifting levels, such as 5 tons, 10 tons, 16 tons and 60 tons.

Door grab ship unloader.

The special machinery derived from the portal crane, also known as the Doumen crane, is mostly used in the harbor bulk cargo unloading operation. The structure is similar to the portal crane, but the door seat is equipped with a funnel and belt conveyor system for receiving bulk cargo, and the hanger is a grab. After grabbing the bulk cargo from the cabin, after lifting and changing amplitude, the grab bucket unloads the bulk cargo into the funnel on the door seat, and then conveys it to the yard by the belt conveyor system. The funnel on the door seat can be moved to minimize the luffing stroke, so the productivity is higher than that of the general portal crane and the structural strength of the jib system is also higher. The productivity of the door grab ship unloader made in China is about 800 tons per hour, which is suitable for bulk cargo unloading in small and medium-sized ports.

Bridge grab ship unloader.

Special unloading machinery for bulk cargo with high productivity (figure 2). The difference between it and the door grab ship unloader is that its horizontal moving grab is realized by the grab trolley running on the crane bridge track, rather than by the pitching of the boom, so it has higher horizontal moving speed and productivity. At present, the productivity of this kind of ship unloader can be as high as 2500 tons per hour.

Quayside container crane.

It is a special crane for container handling ships. It is arranged at the front of the container terminal and is similar in shape to the bridge grab ship unloader. There are many types of quayside container cranes. At present, China uses two front and rear door frames and drawbars to form a gantry, which runs along the front track of the wharf, and the bridge is supported on the gantry (figure 3). In order to avoid collision when the ship is berthing and leaving the wharf, some of the extended cantilevers of the bridge can be pitched and some can be telescopic. The trolley travels back and forth along the track of the bridge to hoist containers. At present, the commonly used lifting speed is 70ft 120m per minute when no load and 35m 50m per minute under heavy load. The trolley runs at a speed of about 120m 150m per minute. It is equipped with special container hoists and anti-rolling devices, with a lifting weight of less than 40 tons. It can lift containers of 20,30TEUs per hour.

Gantry crane.

A bridge crane with a horizontal main beam supported on two rigid legs. The lifting trolley walks on the track of the main beam. There are two kinds of gantry crane: rail type and tire type. The track type walks along the ground track, and the tire type movement is flexible. Mainly used for yard loading and unloading, stacking containers. Chinese-made tire gantry cranes have a lifting capacity of 40 tons, can hold 6 rows of containers within the wheel span, and can be stacked 4 layers across height.

Floating crane.

A jib crane installed on a flat-bottomed boat or special-purpose ship, also known as a floating crane or crane ship (see color picture). Because of its large lifting capacity and maneuverability, and not affected by the change of water level, it is widely used in the loading and unloading operations of seaports and river ports. In the river ports with large water level difference, floating cranes are often equipped with cable cars to carry out loading and unloading operations. The cable car is a kind of wedge-shaped car, which is loaded on the loading platform, is pulled by the hoist and runs on the track of the sloping wharf, which is mostly used for the loading and unloading of goods and heavy goods. The deadweight of the cable car is generally 10 tons, with a maximum of 150 tons. Conveying machinery can continuously transport goods, also known as continuous transport machinery. Goods can be transported on any plane, that is, horizontal plane, inclined plane, and even vertical plane. Conveyors can be divided into two types: those with traction components and those without traction components. The former uses belt, chain, rope and other load-bearing components to transport goods, mainly belt conveyors and chain conveyors, while the latter uses gravity, inertia, friction and air flow to transport goods, mainly pneumatic conveyors.

2. Conveying machinery.

Belt conveyor.

A machine for conveying goods with continuously moving endless conveyor belts. The conveyor belt bypasses the rollers of transmission, redirection, tensioning, etc., and is supported on many rollers. When working, drive the drive drum, move the conveyor belt through the friction between the drive drum and the conveyor belt, and transport the goods on the belt to the unloading place. The most widely used belt conveyor is the belt conveyor, which uses the belt as the conveyor belt. Different tape widths and cushion layers form different specifications. China has produced a series of stereotyped products. The bandwidth of the tape produced in some countries is up to 3000 mm. In long-distance transportation, in order to improve the tensile strength of the conveyor belt, the steel core belt is used, and the conveying distance can be more than 10 kilometers.

Port belt conveyor is used for bulk cargo loading, transshipment and stacking and other operations to form a variety of special machinery, such as coal loader, ore loader. In some countries, the productivity of ore loading machines has reached 20000 tons per hour, with a speed of 6 meters per second. Higher productivity can also be obtained by using the conveyor to unload bulk cargo. In some coal docks along the Mississippi River in the United States, chain bucket ship unloaders are used to unload coal from coal barges with a productivity of up to 3600 tons per hour. The chain bucket ship unloader can also be used for bulk grain unloading. It is composed of a walking door seat, a chain bucket elevator and a belt conveyor. Clamp belt conveyor is a belt conveyor which uses two layers of belt to clamp goods, also known as pressure belt conveyor, is also used for bulk cargo unloading operation.

In order to transport bulk goods or pieces of goods on sloping wharves, China Riverport uses a kind of belt conveyor called “belt truck”.

It installs the frame of the whole conveyor on a narrow rail trolley about 3 meters long, the small workshop adopts hinged connection, the track is laid from the wharf slope through an arc to the wharf surface, the wharf surface is arranged with a hoist, and the whole conveyor is pulled by wire rope to adjust its parking position with the change of water level. At present, the belt trolley has a bandwidth of 650 mm and 800 mm, with a length of 100 to 200 meters, and the productivity of conveying bulk coal is 400 million and 500 tons per hour.

Stacker and reclaimer.

In bulk cargo (such as coal) yard, the bulk cargo transported by conveying machinery is piled up or supplied to transport machinery, mostly using stacker, reclaimer or stacker-reclaimer. Which kind of machinery to choose mainly depends on the type of goods and the requirements of loading and unloading technology. The commonly used stacker and reclaimer is bucket wheel stacker and reclaimer. It is composed of bucket wheel, belt conveyor, frame, walking mechanism and so on. When picking up the material, the bucket wheel rotates, digs the bulk cargo from the pile and pours it on the conveyor belt for output. When stacking, the bulk cargo sent by the conveying machinery is stacked through the belt conveyor. At present, the maximum productivity of bucket wheel stackers and reclaimers produced in China is 2000 tons per hour and 1200 tons per hour.

3. Loading and unloading handling machinery.

Pneumatic conveyer

The machine which uses the air flow formed by the fan in the closed pipeline to transport bulk goods, also known as the pneumatic conveyor. The fan sucks air from the pipeline system, and the goods are sucked into the material pipe from the suction nozzle with the air flow, and the bulk goods are transported in suspension form by the high-speed air flow; then the bulk goods are separated from the air flow by the separator and unloaded by the unloader, and the transportation process is completed. This kind of conveyor is mostly used for bulk grain unloading operation in the port, so it is also called grain suction machine. It has the advantages of simple equipment and good cabin cleaning effect, while the disadvantage is high energy consumption, unable to transport goods with large particle size and large adhesion, and high noise when working. The bulk grain unloading productivity of the pneumatic conveyor has reached 1000 tons per hour.

Loading and unloading handling machinery.

The machines used for loading and unloading, cargo stacking and short-distance horizontal transportation of goods in the port include forklift trucks, straddle trucks, car dumpers, screw unloaders, tractors and trailers, etc.

A forklift truck.

In front of the tire chassis is equipped with lifting door frame and fork handling machinery, referred to as forklift or forklift. Widely used in docks, depots, cabins and cars. When working, insert the fork into the pallet, then lift the fork to lift the goods for stacking operation. The forklift truck has compact structure and good maneuverability, and can walk on the narrow passageway in the warehouse or cabin. If equipped with different pick-up devices, such as string, rotating clamp, hopper, holding clamp, etc., it can load and unload a variety of goods. Large forklift trucks equipped with special container spreaders become special fork loaders for containers. According to the power plant, fork truck can be divided into internal combustion fork truck and battery fork truck; according to the structure, there are balance type, forward type, leg type, side fork type, fork type and so on.

A straddle vehicle.

The handling machine is composed of a door-shaped frame, a lifting frame with a fork and a tire-type walking mechanism (figure 4), also known as a straddle. It is usually driven by an internal combustion engine. Straddle trucks are suitable for handling and stacking large pieces of goods such as steel, wood and long boxes. At work, the door-shaped frame straddles the goods, and the goods are picked up by a fork for handling and stacking. With the development of container transportation, ports in some countries use straddle vehicles to transport containers at the front of the wharf and between the depots and carry out stacking operations in the depot. This kind of container special straddle vehicle is equipped with a container hanger. When the door frame is straddled on the container, the hanger lands on the container, locks the container with hydraulic pressure, and then carries on the hoisting. The lifting height of the hanger should meet the requirements of stacking 2-layer 3-story containers.

A car dumper.

Tipping over the railway gondola to unload the bulk cargo of the special unloader. It has high productivity and is suitable for large professional bulk terminals. According to the structure, the car dumper is divided into two kinds: the rotor car dumper and the side tilt car dumper. When unloading, the gondola carrying bulk cargo goes into the rotor platform of the dumper, presses it with a pressing mechanism, and then rotates 160 °~ 180 °with the rotor, and the bulk cargo is unloaded into the funnel under the rotor and transported out by feeder and belt conveyor. The modern car dumper can accommodate two gondolas at a time, and the two are connected by rotating couplers to realize the unloading operation without disintegration of the train, which greatly improves the unloading efficiency. It turns out that it takes about 3 minutes for a rotor car dumper to unload a truck of bulk cargo, while a modern car dumper takes less than 1 minute to unload a truck.

Screw unloader.

A special machine made in China in the 1970s for unloading bulk coal carried by railway gondolas. It is composed of screw mechanism, rocking mechanism, lifting mechanism, walking mechanism and so on. When unloading, open the side door of the gondola, and the screw mechanism rotates on the bulk cargo from the top of the gondola, unloading the bulk coal and then being transported by the belt conveyor at the bottom of the car. The one-way screw unloader unloads from one side, and the two-way screw unloader unloads from both sides. The screw unloader track is laid on both sides of the railway unloading line. It unloads the car as it moves along the track, with a productivity of 300 tons per hour.

Why are the unloading and safekeeping rates of main equipment and other equipment different?

1. The supplier of the main equipment is generally in place directly, and the unloading fee and storage fee are not given to the construction unit.

2. Other equipment provincial companies generally have material supply companies. Article 889 of the Civil Code of the people’s Republic of China the depositor shall pay the depositary fee to the depositary in accordance with the agreement.
