The filter resistance is small, the filter flow rate is large, the pollution capacity is large, and the service life is long. In the production process, the fiber diameter and gap can be adjusted, and the inner layer of the micropore of the filter element is small and the outer layer is large, which increases the flow rate and the pollution capacity, and the filter element is not easy to block, thus prolonging the service life.
Gas purification in natural gas purification plants, long-distance pipeline stations, urban gas transmission and distribution networks, gas-fired power plants, natural gas chemical plants, coking plants, iron and steel metallurgical plants, before the measurement of non-corrosive gases and other occasions.
