天然氣凈化處理裝置——旋風過濾/快開式過濾分離器

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

燃氣過濾器廣泛用于冶金、化工、石油、造紙、醫藥、食品、采礦、電力、城市、家庭等用氣領域。燃氣過濾器是輸送介質管道上不可缺少的一種裝置，通常安裝在減壓閥、泄壓閥、流量計、定位閥或其它設備的進口端，用來消除介質中的雜質，以保護閥門及設備的正常使用，減少設備維護費用。當流體進入置有濾芯的過濾器后，其雜質被濾芯阻擋，而清潔的濾氣則由過濾器出口排出，當需要清洗時，只要把濾筒拆開，將濾芯取出，清洗后重新裝入即可，因此，燃氣過濾器使用維護方便。

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.
