天然气净化处理装置——旋风过滤/快开式过滤分离器

Natural gas purification unit -- cyclone filter / quick open filter separator

燃气过滤器广泛用于冶金、化工、石油、造纸、医药、食品、采矿、电力、城市、家庭等用气领域。燃气过滤器是输送介质管道上不可缺少的一种装置，通常安装在减压阀、泄压阀、流量计、定位阀或其它设备的进口端，用来消除介质中的杂质，以保护阀门及设备的正常使用，减少设备维护费用。当流体进入置有滤芯的过滤器后，其杂质被滤芯阻挡，而清洁的滤气则由过滤器出口排出，当需要清洗时，只要把滤筒拆开，将滤芯取出，清洗后重新装入即可，因此，燃气过滤器使用维护方便。

Gas filter is widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electric power, city, home and other gas fields. The gas filter is an indispensable device on the medium pipeline. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, flowmeter, positioning valve or other equipment to eliminate the impurities in the medium, protect the normal use of the valve and equipment, and reduce the maintenance cost of the equipment. When the fluid enters the filter with a filter element, its impurities are blocked by the filter element, and the clean filter gas is discharged from the outlet of the filter. When cleaning is needed, just disassemble the filter cartridge, take out the filter element, and then install it again after cleaning. Therefore, the use and maintenance of the gas filter is convenient.
