The rubber joint shall not be exposed to the sun or radiation during use. If it is used outdoors, wrap the rubber joint with insulating cotton after installation, which can 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 to 2 years.
Biogas purification to produce natural gas production equipment mainly depends on large and medium-sized biogas fermentation system engineering or waste treatment landfill. First, China's biogas can be obtained by anaerobic fermentation of living and learning waste, food waste, animal manure, crop straw and other biomass, and then we can purify biogas through membrane separation to improve the quality of natural gas.
However, because the membrane tube has strict requirements on the quality of intake air, desulfurization, dehydration and dust removal must be carried out before biogas enters the compressor However, the desulfurization, dehydration and dedusting of the existing technologies are not perfect, resulting in the failure of desulfurization intensity and activity function from time to time. Dehydration and improper removal also reduce the service life of natural gas pipelines and compressor heads, resulting in huge economic losses.
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; There is too much water in front of the screw compressor, and liquid water appears in the compression process, which corrodes the head and pipeline in case of hydrogen sulfide; The particles of biogas are not removed enough before entering the compressor, which is easy to damage the screw head; The existing water chillers are too large.
