[0002] Biogas is a combustible gas produced by the fermentation of organic matter in an anaerobic environment under certain temperature, humidity and pH conditions through microbial fermentation. Since this gas was originally found in swamps, lakes and ponds, people call it biogas. Biogas has attracted great attention as a renewable and clean energy source with high calorific value. Biogas also contains a certain amount of water, which has a great influence on the utilization of biogas. The water in biogas can work together with hydrogen sulfide to accelerate the corrosion of pipelines, valves, flow meters, etc. Therefore, dehydration treatment is required when desulfurizing biogas, and a dehydrator is required for dehydrating biogas.

After a long period of trial use, dust will adhere to the internal wire mesh, affecting the dehydration effect of the device on biogas, and the practicality is not good. Therefore, this application provides a cooling biogas dehydrator to meet the needs. Utility Model Content

[0026] Working principle: When using the cooling type biogas dehydrator, first introduce the biogas into the dehydration tank 1 from the air inlet pipe 2, and then connect the water inlet pipe 902 to cold water so that the cold water circulates inside the cooling pipe 901. The spiral setting of the cooling pipe 901 can quickly cool the inside of the dehydration tank 1. Under low temperature conditions, the water vapor in the biogas adheres to the steel mesh tube 13, and the dehydrated biogas is discharged from the exhaust pipe 4, and the water inside the dehydration tank 1 is discharged from the drain port 14. Secondly, the setting of the first sealing ring 3 and the second sealing ring 5 can achieve a better sealing effect when the biogas enters and exits the dehydration tank 1, preventing biogas from leaking from the pipe connection.
