Application characteristics of desulfurization and purification system of biogas desulfurizer
沼气脱硫器工艺吸取效果好，吸取剂使用率高，可根据锅炉煤种改变，恰当调理pH值.液气比等因子，以保证规划脱硫率的实现；钠碱循环使用，损耗少，运转成本低；钠碱吸取剂反响活性高.吸取速度快，可采用低液气比，然后既可降低运转费用；脱硫渣无毒，溶解度极小，无二次污染，可综合使用。如气体纯度要求更高可运用双塔。沼气从厌氧发酵设备产出时，特别是在中温或高温发酵时，带着有大量的H2S 。水与沼气中的H2S 一起效果，加速了金属管道.阀门和流量计的腐蚀和阻塞。所以有必要对沼气进行脱硫处理，以保护下流设备的正常运转。
Biogas desulfurizer process absorption effect is good, the use of absorbent is high, according to the change of boiler coal, the appropriate adjustment of pH value, liquid-gas ratio and other factors to ensure the realization of the planned desulfurization rate; sodium-alkali recycling, less loss, low operating costs; sodium-alkali absorbent reactivity is high, absorption speed is fast, low liquid-gas ratio can be used, and then The operation cost can be reduced, the desulfurized slag is non-toxic, the solubility is very small, and there is no two pollution, so it can be used in a comprehensive way. If the gas purity requirement is higher, the Twin Towers can be used. Biogas produced from anaerobic fermentation equipment, especially at medium or high temperatures, carries a large amount of H2S. The effect of water and H2S in biogas accelerates the corrosion and blockage of metal pipes, valves and flowmeters. Therefore, it is necessary to desulphurate biogas to protect the normal operation of the down flow equipment.
The characteristics of biogas desulfurizer are:
1. stable operation and proper operation flexibility.
2. pressure drop during air passage.
3. biogas desulfurization - biogas desulfurizer has simple structure, convenient production and maintenance, low cost and long service life.
4. no scaling. No blockage, wear resistance. Corrosion resistance.
5. Ferric oxide desulfurizer has high strength. The manufacturer of dry desulfurization tower with biogas desulfurizer and biogas matching is specialized in producing and selling fecal treatment equipment.
Effect of biogas desulfurizer
1., local resources can be used instead of import power to reduce the country's dependence on import power.
2., diversifying the use of fuel in China and reducing the reliance on a power.
3. A relatively clean power, using biogas instead of mineral fuels is an ambitious way to reduce CO2 emissions (methane is the main component of biogas, and its greenhouse effect is 21 times that of carbon dioxide);
Maintenance and protection status of biogas desulfurizer
1. check regularly whether there is air leakage in the flange seal. If yes, tighten bolts or replace rubber pads.
2. However, the content of H2S in biogas before desulfurization should be detected regularly, and the content of H2S after desulfurization should also be detected. When the desulfurization power is below 90%, it is clarified that the desulfurizer is close to the full sulfur capacity and the desulfurizer is invalid. The desulfurizer should be replaced. Some of the invalid desulfurizer can be removed from the bottom of the desulfurization tower and some of the new desulfurizer can be made up from the top.
