Dry desulfurization equipment 1.Remove H2S by using desulfurizer. 2.Good performance. 3.High efficient of H2S removal. General descriptionDry desulfurization system is standard equipment we designed and produced according to the content of H2S in the gas, the actual content of gas, the life cycle, and other relevant data of the clients,specially design the dimension and the internal structure. Different kind of gas, different content of H2S in the gas, different pressure, the dimension and the internal structure is different, too. For real-time monitoring the reaction speed of sulfide and the oxygen in air in the process of regeneration, we added temperature monitoring equipment, this can avoid accident fires(When the content of the entered air is large, the exothermic reaction is violent, the temperature is above the sulfur's ignition point, this caused accidental fires. ) in the process of regeneration. The design and the production must according to the technological requirements, in the process of biogas power generation, purify the biogas by systematic desulfurization, dehydration, etc according to the actual demand biogas generation capacity. The desulfurization use the combination of physical and chemical technology, the dehydration use machinery, gas water separation membrane technology, has high efficient, easy to manage, low investment, long life, operating reliable, high desulfurization rate, and other advantages. The system applicable to gas with low content of H2S, small air flow, high precision of desulfurization, especially the best assurance for high-quality generators.1,Theory of dry desulfurizationH2S was oxidized to sulfur or sulfide by using O2, also called dry oxidation method. Another method(common method) is dedicated ferric oxide(MT dedicated ferric oxide desulfurizer) absorption method, by using the activity Fe2O3 to adsorb H2S, make it into the iron sulfide, then can remove the H2S.The consist of dry equipment: put filling into one tank (the packing layer can be ferric oxide desulfurizer, active carbon desulfurizer, etc. The best is ferric oxide desulfurizer, because it has high sulfur capacity and low cost.). The gas go through the packing layer from one side of the tank with low speed, H2S was oxidized to sulfur or sulfide or iron sulfide, stayed in the pacing layer, and the purified gas discharged from other side of the tank.Flow of process:biogas→dehydration→desulfurization→fire resistance→generate electricity or boiler combustion2,Features of dry desulfurization1),Simple structure, convenient to use. 2),Dispense with staff on duty, refueling at fixed period, one use one reserve, alternate operation. 3),Compared with wet method, need refueling at fixed period.4),Applicable to gas with small air flow, high precision of desulfurization.4,Application of dry desulfurization equipmentAccording to the input content of H2S, air flow per hour, and the life cycle, to design and produce the desulfurization tank (or thionizer), gas-water separator, flame arrester, air blower, buffer tank, desulfurizer device, water seal, pressure gage, flowmeter, supporting pipe valves, etc.Dry desulfurization equipment can used in the purification system of biogas, farm, starch, papermaking, sewage treatment, alcohol, chemical fiber,pharmacy, fertilizer, coking, landfill, coal gas, natural gas, ceramics, food, maize further processing, citric acid, and other industries.
