Liquid nitrogen air temperature vaporizer
Product Description
Liquid Nitrogen Air Temperature Vaporizer
This series of vaporizers use the heat of air to heat the low-temperature liquid in the heat exchange tube. The fins of the heat exchange tube absorb the heat in the air and transfer it to the low-temperature liquid in the tube to vaporize it into a gas. The air-heated vaporizer does not require electricity or steam consumption. It is a new type of high-efficiency and energy-saving gasification equipment, and it has no moving parts, no maintenance, and no noise. It is widely used in liquid oxygen, liquid nitrogen, and liquid. Vaporization of cryogenic liquids such as LNG.
Product Details
Product structure and working principle
This series of gasifiers are tube-type, connected by star-shaped fin tubes. The unique "bridge" connection improves the gasification capacity and the flexibility of the equipment. The connection between the fins does not require welding, and the internal stress is small, and the structure is compact. , The arrangement is even, beautiful and durable.
LNG air-heated vaporizer uses natural convection of air to heat the low-temperature liquid in the heat exchange tube to completely evaporate it into gas; it is a high-efficiency and energy-saving exchange of air-collecting temperature and heating vaporization functions, which can replace heating vaporization products. Thermal equipment. Vaporizers vaporize low-temperature liquid gas into a gas of a certain temperature through heat exchange, and are classified into three types according to their uses: high, medium, and low pressure.
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 a high-pressure gas and fill it into a steel cylinder. The low-pressure vaporizer vaporizes the low-temperature liquid in the storage tank into low-pressure gas, which is transported to the site of use through a pipeline through a pressure regulating device. The air-heated vaporizer is a high-efficiency and energy-saving product. Compared with the water-bath electric heating vaporizer and the steam-heating water-bath vaporizer, it can save a lot of electricity or steam.
The structural characteristics of the vaporizer can ensure the normal operation of all parts under the cryogenic temperature, avoid sealing freezing, good sealing, safe and reliable, non-corrosive, and long service life. Using special ￠120, ￠160, ￠200 large-diameter dedicated aluminum finned tubes, the defrosting speed is extremely fast.
The welding seams of all parts of the vaporizer are welded by argon arc welding, the welding seams are neat and beautiful, and there is no pore defect. Optimize the process design, minimize the pressure, no bias flow phenomenon, and ensure that the flow rate is controlled within a safe range.

Small LNG gasification skid-mounted station is a complete set of equipment that integrates LNG storage tanks, air-temperature vaporizers, pressure regulators, metering devices, and safety control devices, and can directly provide gas sources to residential communities and industrial users.
Star-shaped finned tube
The star-shaped fin tube is the core component of the vaporizer, which is the wrong way to absorb heat and vaporize. The material of the fin tube is rust-proof aluminum. The fin tube of the fin tube usually has 8 fins and 12 fins. Finned tube The outer diameter mainly consists of two specifications, φ160mm and φ200mm, and φ200mm is usually used for large-scale vaporization.
Material and technology
All parts are made of aluminum alloy and stainless steel with excellent oxidation resistance and high performance. The high-pressure connection between the stainless steel core tube and the fin is tight. Before leaving the factory, they are dried with nitrogen in accordance with oxygen standards to ensure product quality and safer use.
