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.
The air-heated vaporizer is mainly composed of star-shaped vaporization tube fins, liquid-gas guide tube, base, bracket, inlet and outlet joints, etc.
Star-shaped vaporized tube fin: The material is made of LF anti-rust aluminum alloy, with a diameter of 115mm or 160mm, each with 8 wings symmetrical, with good vaporization effect, sturdiness and durability, corrosion resistance and weathering resistance.
Liquid diversion tube: The material is made of copper tube or 0Cr18Ni9 stainless steel tube, which is resistant to high pressure and impact.
Base and support: Angle aluminum is selected as the material, which is durable, corrosion-resistant and durable.
The main technical parameters
Suitable medium: LNG, NG, CNG, LO2, LN2, LAr, LCO2, NH3, LPG, etc.;
Working pressure: 0.1-40MPa;
Single unit gasification capacity: 20—10000Nm³/h, no matter how large the specification is, it is not convenient to transport, please choose multiple units;
Equipment classification: vaporizer, heater, supercharger, etc.
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.
This air-heated vaporizer is a highly energy-efficient product. Compared with the water-bath electric heating vaporizer and the steam-heating water-bath vaporizer, it can save a lot of electricity and steam.
The structural characteristics of this vaporizer can ensure that the components have normal working pressure at cryogenic temperatures, avoid sealing freezing, and have the characteristics of good sealing performance, safety, reliability, non-corrosiveness, and long service life.
The carburetor has a compact structure, uniformly arranged, neat, beautiful and generous, and the fin tube adopts a large fin tube.
The welding seams of all parts of this vaporizer are welded by argon arc welding, the welding seams are neat, beautiful, free of undercuts, pores and other defects.
The vaporizer is strictly cleaned when leaving the factory, and the oil and grease are removed. The water pressure test and the air tightness test are performed. There is no leakage. After the pressure test, they are all blown dry with dry nitrogen.
The air-heated vaporizer realizes its gasification function by relying on its own sensible heat and absorbing the heat of the outside atmosphere. This is its advantage.
