What should we pay attention to when rubber joint can be used in biogas purification system? Next, let's share it with you.
The rubber joint shall not be exposed to the sun or radiation in the process of use. If it is used outdoors, the rubber joint shall be wrapped with insulating cotton after installation, so as to isolate the ultraviolet radiation and avoid the rapid aging of the rubber on the surface of the rubber joint. A small change can increase the service life of the rubber joint by 1-2 years.
The purification of biogas to produce natural gas production equipment mainly depends on large and medium-sized biogas fermentation system engineering or waste disposal landfill. First of all, China's biogas can be obtained by anaerobic fermentation of living and learning waste, kitchen waste, animal manure, crop straw and other biomass. Then we purify biogas by membrane separation method to improve the quality of natural gas. However, due to the strict requirements of the membrane tube on the intake quality, before the biogas enters the compressor, it is necessary to carry out desulfurization, dehydration and dedusting.. however, the existing technology of desulfurization, dehydration and dedusting is not perfect enough, resulting in the failure of desulfurization intensity and activity function, dehydration and improper removal, which also reduces the service life of the natural gas pipeline and compressor head A huge economic loss. For example, the existing system lacks a water removal device in front of the iron oxide desulfurizer, and the desulfurizer is liable to fail in case of liquid water; the water content in front of the screw compressor is too much, and the liquid water appears in the compression process, which corrodes the machine head and pipeline in case of hydrogen sulfide; the particles of biogas are not removed enough before entering the compressor, and the screw head is damaged easily; the existing water chiller is too large.
The above are the precautions for biogas purification. If you want to know more, please consult Website.
