The air-temperature vaporizer is a device that uses natural convection of air to heat the low-temperature liquid in the heat exchange tube and completely evaporate it into gas. It is a heat exchange equipment that integrates air temperature and heating vaporization functions and can replace heating vaporization products. Its structural features can ensure the normal operation of each component under cryogenic temperatures and avoid seal freezing. It has good sealing performance, is stable and reliable, non-corrosive and has a long service life. The welds at the joints of all parts of the equipment are welded by argon arc welding. The welds are neat, beautiful and free of pore defects.
When using an air-temperature vaporizer to completely evaporate low-temperature liquids, there are the following points to note:
1. During operation, the working pressure of the equipment should be strictly controlled to keep it within the normal range and avoid the pressure being too high or too low.
2. If there is frost in the equipment, it needs to be removed in time to avoid affecting the heat exchange effect.
3. When the temperature is low in winter, special attention needs to be paid to the air supply capacity of the equipment, because the lowering temperature will cause the frost on the fin tubes to not melt in time, and the frost will accumulate thicker and affect the heat exchange capacity between the air and the equipment.
4. If the air-temperature vaporizer is in an overload working state, that is, the user's gas consumption exceeds its vaporization capacity, the gas temperature at the outlet of the equipment will be lower than the design value, and even low-temperature liquid will enter the user end without being vaporized.
