e-PTFE堆肥膜··智能控制系统··微压送风系统··监控系统

The core equipment of the membrane-covered system is the GT-composite membrane (covering membrane) that is placed on the livestock manure pile. The film is assembled from an e-PTEF film mating substrate which is sandwiched between two layers of a strong polyurethane substrate film. The e-PTEF film is uniformly distributed with pores of 0.2 μm pore size, and the polyurethane film has the characteristics of ultraviolet protection and corrosion resistance. The high-temperature aerobic fermentation pre-fermentation reactor is sealed with the membrane-sealed livestock and poultry manure to shield the wind and rain from the adverse weather, and at the same time, the carbon dioxide gas and water vapor entangled in the treatment process can be quickly discharged. The water permeability of the membrane affects the change of moisture during the treatment process, which requires the material to be too wet and retain sufficient moisture for the degradation of the material. The e-PTEF membrane has a certain insulation and pressurization effect, which can help the system maintain the temperature, so that the oxygen concentration and temperature in the stack are evenly distributed, which is beneficial to the temperature condition of the entire heap to kill the pathogen. The 0.2 μm pore size micropores on the e-PTEF membrane are effective physical barriers to dust, aerosols and microorganisms, preventing them from spreading out. During the pre-fermentation process, a film of condensed water is formed on the inner surface of the membrane; most of the odorous substances in the exhaust gas, such as ammonia, hydrogen sulfide, volatile organic compounds (VOC), etc., are dissolved in the water film. Then, it will fall back to the pile with water droplets, where it will continue to be decomposed by microorganisms. The cover film can reduce the odor concentration in the fermentation process by 90%-97%, and reduce the microorganisms in the exhaust gas by more than ***. Protect the health of field workers and the surrounding residents.
