The structure of welding filter1

Structure of welding filter restricted by air volume difficult to expand due to welding filter, so the pipe welding filter, the filter is mainly used in the fibrous, non-corrosive, temperature is not higher than 300 ℃ the dust gas purification treatment, is widely used in mining, chemical, coal, building materials metallurgy, electric power and other industries. The environmental protection department testing, various performance indexes reach the advanced level in the filter. The overall structure of the filter is divided into upper and lower body of two parts. Case on include in and out of the air duct, distribution, air hose, two water retaining plate, nozzle, centrifuge ( Type I not including centrifuge) 。 Frame including the mud bucket, water spray, dust catcher under other equipped with electric putter, liquid level switch, solenoid valve and u-shaped pressure gauge, etc. Welding filter dust by gas after entry into the larger dust particles blocked grey board stand behind are removed, small dust particles into the header along with the air, then dust after a blast pipe, gas from the nozzle at the high speed, the impact on a large amount of liquid surface bubbles and water droplets, to purify air with dust. After purification, the air in under the action of negative pressure, through the first water retaining plate and the second water retaining plate by discharge outlets. After purification, the gas contained in the water by the first and second manger.
