The biogas desulfurization and dehydration equipment has high efficiency, small size, convenient installation and use, and the internal stainless steel wire mesh can be repeatedly cleaned. When the hydrogen sulfide in the biogas contacts with iron oxide and the iron sulfide generated by the chemical reaction is grayish black, the desulfurization agent loses its effectiveness and needs to be regenerated or replaced.
Pour out the ineffective desulfurizer from the bottle and rinse it with clean water to remove the sludge brought by biogas. Due to the large amount of hydrogen sulfide in biogas, commonly used dry desulfurization methods include activated carbon method, iron oxide method, and zinc oxide method. After three months, regeneration or replacement of desulfurizers should be carried out, which has a significant impact on the utilization of biogas and causes pollution and corrosion to the environment, equipment, pipelines, and instruments. Therefore, untreated biogas cannot be used.
Secondly, the methane desulfurization and dehydration equipment can soak up iron oxide particles in the water, but still retain some air vents; Once again, the porous tube is set up in the air, so that the moisture accumulation inside the desulfurization bottle exists under the suspended porous tube. The advantage is that it can remove both hydrogen sulfide and organic sulfur, with higher purification compared to wet desulfurization. It can remove H2S from the gas to below 20mg/m3. Commonly used dry desulfurization methods include activated carbon method, iron oxide method, and zinc oxide method.
After pouring out the desulfurizer, remove the broken foam first, and then place the granular desulfurizer on the cement floor or iron plate to cause pollution and corrosion to the environment, equipment, pipelines, and instruments. Pour out the ineffective desulfurizer from the bottle, rinse with clean water to remove the mud foam brought by biogas, and then spread it on the cement floor and turn it over appropriately (can spray a small amount of dilute ammonia water), Using oxygen in the air to oxidize iron sulfide back into iron oxide.
