Brick factory bag dust collector

    During the production process of bricks and tiles, raw material crushing, screening, molding and other processes are easy to produce a large amount of dust, which not only affects the workshop environment, but also has a potential impact on the health of employees. The bag-type dust collector adopts the physical filtering principle. When the dust-containing gas passes through the high temperature resistant fiber bag, the dust will be intercepted to form a dust cake, and the clean air will be discharged from the system. Its core advantages lie in the combined effect of multiple filtration mechanisms: inertial collision captures large particles, electrostatic adsorption processes fine dust, and diffusion deposition intercepts PM2.5. This filtration ensures efficient capture of the unique silicate dust of the brick factory.

    In view of the characteristics of high temperature and high humidity of the brick factory, the professional dust removal equipment adopts special material filter bag: PTFE coated filter bag can withstand 260 ℃ high temperature, and the glass fiber material is resistant to acid and alkali corrosion. The intelligent pulse dust removal system adopts reverse blowing of 0.4-0.6MPa compressed air to accurately control the dust removal frequency, which not only avoids damage to the filter bag due to excessive dust removal, but also prevents the effect of too thick dust cake on the efficiency. The actual operation data shows that this combined technology can stably control the outlet dust concentration below 10mg/m3.

    The application of bag-type dust collector in brick factory shall focus on three links: it is suggested to adopt semi-closed dust hood in raw material crushing section, and the wind speed shall be less than 15m/s, so as to effectively collect dust generated during crushing; High-temperature resistant filter bag shall be selected and flue gas cooling device shall be set in the burning workshop; The packing area should be of ash hopper structure for continuous ash discharge. The example of an enterprise with an annual output of 100 million standard bricks shows that the dust emission is reduced by 43 tons and the concentration of PM10 in the working environment is reduced by 92% after the system is reconstructed.
