The advantages of various types of dust collectors produced by Hebei Feixiang Environmental Protection Equipment Co., Ltd. for mining use, including back blowing and pulse blowing in the collection chamber, are high air volume per unit volume, low system resistance, and low air leakage rate during shell production; 2%. The upper box and ash hopper are all made of 100 thick insulation cotton to prevent smoke and dust from entering the dust collector and causing condensation after cooling; It can directly process other dust containing substances up to 200g/nm3, with emissions concentrations below 20mg/nm3 after treatment. It can also meet stricter emission requirements according to user needs; Used for dust removal in coal powder systems, dust removal bags and measures are taken according to the properties of coal powder;, Generally, it can capture small dust particles with a particle size greater than 0.3 microns and meet strict environmental requirements.
