electric heating water bath gasifier
this series of gasifiers use high-efficiency electric heating to heat the water in the cylinder and the low-temperature liquid (lo2, ln2, lar, lng, lco2, lc2h4, lpg) in the compact heat exchange tube. the advanced water temperature automatic control system is adopted to ensure that the gas outlet temperature meets the design requirements. the equipment does not need personnel on duty, no vibration and noise, and has long service life.
according to the gasification gas or use requirements, lng, liquid ammonia and other flammable media are made into explosion-proof electric heating gasifier.
product structure and principle
the main process of the water bath gasifier (heater) is to exchange heat between the low temperature liquid (gas) in the tube side and the heat medium in the shell side, so as to make the gas temperature at the pipe outlet reach the set value.
the medium in the tube side of water bath evaporator or heater is mainly low temperature liquid or gas such as oxygen, nitrogen, argon, natural gas, carbon dioxide, liquefied petroleum gas, ethylene, helium, etc. it is mainly used in metallurgy, chemical industry, petrochemical, civil / industrial gas station, mechanical processing, electronics, medicine, military and aerospace industries.
main technical parameters

user optional configuration
● the cylinder is made of carbon steel or stainless steel;
● sound and light alarm for high and low outlet temperature;
● installation of emergency cut-off device;
● overall skid mounting and design of equipment;
● it can be designed and manufactured according to electronic standard;

characteristics of electric heating gasifier
1. the diameter of the outer cylinder is large;
2. the operation is quiet;
3. the optimal design of heat exchanger is as follows
① full contact heat transfer is adopted
② the distance between the heat exchange tube and the heat exchange tube in the subcooled section and the two-phase section is designed in sections, which has high heat exchange efficiency and avoids the possibility of freezing in the subcooled section
③ the distance between the whole heat exchange device and the cylinder is large to avoid frost cracking or deformation of the cylinder
4. the optimal design of flow rate;
5. professional pipeline internal inspection equipment.
