On September 29, 2019, China Environmental Protection Industry Association issued the "Implementation Guide for Ultra-Low Emission Transformation of Iron and Steel Enterprises (Draft for Comment)" (Environmental Union Technology [2019]76).，To promote the implementation of ultra-low emissions in the steel industry，Provide relevant ultra-low emission transformation technology route selection, engineering design and construction, facility operation and management for reference。

       Among them, "using high efficiency folding bag filter" is the main recommended treatment measure, and it is suggested to use high efficiency folding bag filter dust removal technology to transform the existing bag dust collector。0 is recommended.7m/min full filter wind speed;Binding strength greater than 500N;According to the inlet dust concentration and dust characteristics, choose between 32 and 46 filter cartridge fold。

       Haoke Technology is committed to using folding filter bag dust removal technology to transform the existing filter bag dust collector，By this means，In the case of the original filter bag dust collector flower plate and box structure unchanged，Increase the filtration area, reduce the filtration wind speed, and increase the free settling space，To achieve ultra-low dust emission requirements，And reduce the dust on the filter material wash。At the same time, the original dust collector equipment basically does not need to be reformed, which reduces the cost and time of transformation for users。

(Good science and technology release)
