Secondary characteristics of biogas desulfurization
安全；脱硫塔和硫反响器的别离，防止了沼气与空气的间接接触，消弭了平安隐患。
Safety; The separation of desulfurization tower and sulfur reactor prevents indirect contact between methane and air and eliminates potential safety hazards.
The cost is low; the cost of investment and operation is greatly reduced due to the increase of alkali consumption, the recovery of sulfur and the localization of biogas desulfurization technology and equipment.
Biological recycling application of alkaline solution; absorbing H2S with alkaline solution, then oxidizing the absorbed sulfide into elemental sulfur under the action of selected microorganisms and air in nature, the biochemical reaction will regenerate alkali, make alkali lose and regenerate, and return to the wash tower, which in fact does not consume alkali.
Sulphur recovery; hydrogen sulfide absorbed by alkali liquor is oxidized to elemental sulfur in biochemical reactor, elemental sulfur is separated after successive sulfur precipitator and separator, so that waste gas hydrogen sulfide is lost and recovered, added revenue and reduced desulfurization cost. While removing hydrogen sulfide, the elemental sulfur is recovered.
Fragmentation disadvantage; high removal efficiency of hydrogen sulfide, high biological activity, strong impact resistance, quick start-up time, process fluctuation, complex operation, can operate at room temperature and pressure, low operating costs (compared with alkali scrubber, can waste more than 90%), no need for iron chelates, no subsequent toxic products, biochemical recovery of elemental sulfur can be reacted. Use.
In summary, all the above-mentioned Shandong Heneng Environmental Protection Energy Equipment Co., Ltd. provides, want to know more about biogas desulfurization knowledge, welcome to pay attention to our website: https://www.hneee.net Thank you for your support!
