Biogas desulfurization is the difficulty of biogas engineering. The traditional wet desulfurization process will consume a lot of water, while the reaction process of biogas biological desulfurization equipment and biogas desulfurizer will generate water, which greatly reduces the water consumption. Let's take a look at how biogas biological desulfurization equipment and biogas desulfurizer work!

Principle introduction of biogas biological desulfurization equipment and biogas desulfurizer
A certain amount of air is introduced into the biogas containing hydrogen sulfide, and a large number of biological fillers are installed in the reactor to provide sufficient space for bacterial growth. The circulation of nutrient solution (NPK) can keep the filler moist and supplement the nutrients required for bacterial growth and reproduction. Proprietary Corynebacterium and Thiobacillus absorb hydrogen sulfide during metabolism, convert it into elemental sulfur, and then convert it into sulfuric acid.
在营养液的缓冲和中和作用下，将得到的稀硫酸与营养液一起从系统中排出，并重复此过程。
Under the buffering and neutralizing action of the nutrient solution, the obtained dilute sulfuric acid is discharged from the system together with the nutrient solution, and the process is repeated.

Progress analysis of biogas biological desulfurization equipment and biogas desulfurizer
Methane enters the bottom of the reactor and passes through the filling layer from bottom to top. Add air accurately through frequency conversion control. The exhaust gas composition analyzer monitors the residual oxygen concentration and works with the blower. Nutrient solution is added regularly by metering pump. The liquid level switch controls the overall liquid level balance.
In order to ensure the good activity of bacteria, heat exchangers and temperature monitors are used to regulate and control the system temperature. PH meter is used to control the quality (acidity) of nutrient solution. For example, if the pH value is lower than the set value, fresh nutrient solution and dilution water will be automatically added to the desulfurization tower. At the same time, the waste liquid is discharged automatically, and the liquid level is balanced.
