Working principle of biogas refrigerated dryer
The wet and hot biogas from the biogas refrigerated dryer first passes through a gas heat exchanger (precooler) and exchanges heat with low-temperature biogas from the low dew point outlet of the evaporator to reduce the inlet temperature. Then, it enters the evaporator and exchanges heat with the refrigerant of the refrigeration system to further cool the biogas to the set temperature (2-10 ℃). The water vapor in the biogas condenses into droplets and is separated by an efficient steam water separator before being discharged outside the machine. Thus achieving the goal of reducing moisture content. After dehydration, the low-temperature biogas returns to the gas heat exchanger and exchanges temperature with the inlet biogas to complete drying and purification. The relative humidity of the heated gas decreases. Avoid rusting inside the rear pipeline and external condensation and dripping.

The biogas refrigerated dryer has no vulnerable or consumable spare parts, good performance, long equipment life, and low operating costs. It solves the problem of low combustion value and high generator failure rate caused by high gas moisture content in the purification process of biogas for power generation.
The explosion-proof gas freeze dryer for biogas, gas, and other gases jointly developed by the company, the School of Environment at Tsinghua University, and Nanjing University has also played a role in various atmospheric engineering projects. In recent years, there has been a significant investment in the utilization of various types of exhaust gases. The flue gas emitted from various sources is cooled and filtered through freeze-drying, which not only solves the problem of emission pollution but also enhances the value of gas utilization;
The company has a comprehensive quality assurance system, advanced testing equipment, and a high-quality workforce, providing users with a series of services such as design, installation, and after-sales service for compressed air and special gases.
