沼氣提純系統(tǒng)可以使用橡膠接頭時(shí)候我們應(yīng)該需要注意哪些？接下來由沼氣提純的小編來給大家分享一下。
What should we pay attention to when rubber joint can be used in biogas purification system? Next, let's share it with you.
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(gè)小小的改變可以讓橡膠接頭使用壽命增長1~2年。
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.
沼氣進(jìn)行提純制取天然氣生產(chǎn)設(shè)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(duì)生活學(xué)習(xí)垃圾、餐廚垃圾、動(dòng)物糞便、農(nóng)作物秸稈等生物質(zhì)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(dá)到提高天然氣的品質(zhì)。 但由于膜管對(duì)進(jìn)氣質(zhì)量有嚴(yán)格的要求，所以在沼氣進(jìn)入壓縮機(jī)之前，必須進(jìn)行脫硫，脫水，除塵..然而，在現(xiàn)有技術(shù)的脫硫，脫水，除塵方面還不夠完善，造成這種情況時(shí)有發(fā)生脫硫強(qiáng)度和活動(dòng)功能衰竭，脫水，去除不當(dāng)也降低了天然氣管道和壓縮機(jī)頭的壽命，造成巨大的經(jīng)濟(jì)損失。如，現(xiàn)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(jī)前含水過多，壓縮過程出現(xiàn)液態(tài)水，遇硫化氫腐蝕機(jī)頭和管道；沼氣在進(jìn)入壓縮機(jī)前顆粒清除不夠，易損壞螺桿機(jī)頭；現(xiàn)有冷水機(jī)組過于龐大。
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 http://www.jdl123.com Website.
