The heat pipe of the LNG ambient vaporizer is extruded from fins and pipes, and the cross section of the heat pipe is a star-shaped fin. The LNG vaporizer is composed of an evaporation part and a heating part. The evaporating part is composed of heat-conducting tubes connected side by side with end plate tubes, and the heating part is composed of heat-conducting tubes connected in series with elbow joints.
The LNG ambient vaporizer uses natural air convection to heat the low-temperature liquid in the heat exchange tube to make it completely evaporate into gas; it is a high-efficiency energy-saving gasifier that integrates air ambient and heating vaporization functions and can replace heating and vaporization products. thermal equipment. The vaporizer is to vaporize the low-temperature liquid gas into a gas at a certain temperature through heat exchange, and is divided into high, medium and low pressure according to the purpose. The high-pressure vaporizer is to vaporize liquid oxygen, liquid nitrogen, liquid argon, and liquefied natural gas after being pressurized by a cryogenic liquid pump into high-pressure gas and fill it into a steel cylinder. The low-pressure vaporizer vaporizes the low-temperature liquid in the storage tank into a low-pressure gas, which is transported to the use site through a pressure regulating device through a pipeline. The air-heated vaporizer is a high-efficiency energy-saving product, which can save a lot of electricity or steam compared with the water-bath electric heating vaporizer and the steam heating water-bath vaporizer.
The structural characteristics of the carburetor can ensure the normal operation of all parts at cryogenic temperatures, avoid sealing and freezing, good sealing, safe and reliable, non-corrosive, and long service life. Special ￠120, ￠160, ￠200 large-diameter special aluminum finned tubes are adopted, and the defrosting speed is extremely fast. The welds at the joints of all parts of the carburetor are welded by argon arc welding, the welds are neat and beautiful, and there is no air hole defect. Optimize the process design to minimize the pressure, without bias flow, and ensure that the flow rate is controlled within a safe range.
