沼氣提純系統(tǒng)使用橡膠接頭時候應該注意哪些？

What should be noted when using rubber joints in biogas purification systems?

　　橡膠接頭在使用的過程中避免受到太陽的照射或輻射，如果在室外使用，安裝后用保溫棉把橡膠接頭包裹起來，這樣就可以起到隔離紫外線輻射的問題，可以避免橡膠接頭表層橡膠快速老化，一個小小的改變可以讓橡膠接頭使用壽命增長。

Rubber joints should avoid exposure to sunlight or radiation during use. If used outdoors, wrap the rubber joints with insulation cotton after installation to isolate UV radiation and prevent rapid aging of the surface rubber of the rubber joints. A small change can increase the service life of the rubber joints.

　　沼氣進行提純制取天然氣生產設備主要依賴于大中型沼氣發(fā)酵系統(tǒng)工程或垃圾處理填埋場，首先可以通過對生活學習垃圾、餐廚垃圾、動物糞便、農作物秸稈等生物質厭氧發(fā)酵，獲得中國沼氣，然后我們通過膜分離法提純沼氣，使之達到提高天然氣的品質。

The purification of biogas to produce natural gas production equipment mainly relies on large and medium-sized biogas fermentation system engineering or waste treatment landfill sites. Firstly, Chinese biogas can be obtained through anaerobic fermentation of biomass such as household and learning waste, kitchen waste, animal manure, and crop straw. Then, we purify biogas through membrane separation to improve the quality of natural gas.

　　但由于膜管對進氣質量有嚴格的要求，所以在沼氣進入壓縮機之前，必須進行脫硫，脫水，除塵。

However, due to the strict requirements of the membrane tube on the intake quality, desulfurization, dehydration, and dust removal must be carried out before biogas enters the compressor.

　　然而，在現有技術的脫硫，脫水，除塵方面還不夠完善，造成這種情況時有發(fā)生脫硫強度和活動功能衰竭，脫水，去除不當也降低了天然氣管道和壓縮機頭的壽命，造成巨大的經濟損失。如，現有系統(tǒng)在氧化鐵脫硫塔前缺乏除水裝置，脫硫劑遇液態(tài)水易失效；螺桿壓縮機前含水過多，壓縮過程出現液態(tài)水，遇硫化氫腐蝕機頭和管道；沼氣在進入壓縮機前顆粒清除不夠，易損壞螺桿機頭；現有冷水機組過于龐大。

However, the existing technology for desulfurization, dehydration, and dust removal is not yet perfect, resulting in the failure of desulfurization intensity and activity function. Improper dehydration and removal also reduce the service life of natural gas pipelines and compressor heads, causing huge economic losses. For example, the existing system lacks a water removal device in front of the iron oxide desulfurization tower, and the desulfurizer is prone to failure when it comes into contact with liquid water; There is too much water in front of the screw compressor, and liquid water appears during the compression process, which corrodes the machine head and pipelines when encountering hydrogen sulfide; Insufficient particle removal of biogas before entering the compressor can easily damage the screw head; The existing chiller units are too large.
