沼气提纯系统可以使用橡胶接头时候我们应该需要注意哪些?接下来由沼气提纯的小编来给大家分享一下。
What should we pay attention to when rubber joint can be used in biogas purification system? Next, let's share it with you.
橡胶接头在使用的过程中避免受到太阳的照射或辐射,如果在室外使用,安装后用保温棉把橡胶接头包裹起来,这样就可以起到隔离紫外线辐射的问题,可以避免橡胶接头表层橡胶快速老化,一个小小的改变可以让橡胶接头使用寿命增长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.
沼气进行提纯制取天然气生产设备主要依赖于大中型沼气发酵系统工程或垃圾处理填埋场,首先可以通过对生活学习垃圾、餐厨垃圾、动物粪便、农作物秸秆等生物质厌氧发酵,获得中国沼气,然后我们通过膜分离法提纯沼气,使之达到提高天然气的品质。 但由于膜管对进气质量有严格的要求,所以在沼气进入压缩机之前,必须进行脱硫,脱水,除尘..然而,在现有技术的脱硫,脱水,除尘方面还不够完善,造成这种情况时有发生脱硫强度和活动功能衰竭,脱水,去除不当也降低了天然气管道和压缩机头的寿命,造成巨大的经济损失。如,现有系统在氧化铁脱硫塔前缺乏除水装置,脱硫剂遇液态水易失效;螺杆压缩机前含水过多,压缩过程出现液态水,遇硫化氢腐蚀机头和管道;沼气在进入压缩机前颗粒清除不够,易损坏螺杆机头;现有冷水机组过于庞大。
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 https://www.hneee.net Website.
