Double-layer cloth bag-suction-type cloth bag dust collector

Abstract

The invention discloses a double-layer cloth bag-suction-type cloth bag dust collector. Gas to be subjected to dust removal enters a box from the lower end of a dust removal cavity, when dust-containing gas penetrates through a lower-layer dust removal cloth bag, a part of dust is adsorbed, the gas after the primary dust removal enters the upper end of the dust removal cavity under the pressure at an inlet end of the dust removal cavity, the dust-containing gas penetrates through an upper layer dust removal cloth bag, the dust is further absorbed, the dust content of the gas is monitored by a dust concentration detector, if the dust concentration is lower than the national stipulated emission standard, a fan is started to pump out clean air in the dust removal cavity, and after the apparatus works for a period of time, the upper layer dust removal cloth bag and the lower layer dust removal cloth bag are driven by an active synchronous belt pulley to rotate so as to remove the attached dust, so that the dust removal efficiency is improved. The double-layer cloth bag-suction-type cloth bag dust collector solves the problems of the dust collector such as low efficiency and poor effect and is simple in structure.

Description

technical field [0001] The invention relates to a bag filter. Background technique [0002] The function of the dust removal system is to collect and treat the waste gas and dust generated in the main engine and other devices, and discharge the gas that meets the requirements of environmental protection. composition. When working, the dust with larger particle size is separated and collected by the gravity dust collector, and the bag dust collector filters the fine dust. [0003] The main frame of the bag filter is formed by the butt joint of the upper box and the lower box. A large number of dust-removing bags are installed on the upper box. The cross section of the lower box is trapezoidal. Generally, the bag filter uses the principle of atmospheric back blowing to clean the dust bag, so it must work in a negative pressure environment. The dust-laden gas enters the inlet of the bag filter, and after being filtered by the filter bag, the dust adheres to the filter bag, a...

AI Technical Summary

Problems solved by technology

Although the combination of the two dust removal methods of electrostatic precipitator and bag filter can improve the work efficiency and dust removal effect to a certain extent, it still has many shortcomings, such as only the injection device is designed, and there is no design at the outlet of the ash hopper. The suction device will inevitably cause the dust to not easily reach the ash hopper after the blowing device works, thereby reducing the dust removal effect

[0006] To sum up, the existing turning equipment mainly has defects such as too complicated and bulky structure principles, insufficient consideration of details, loud working noise, insensitive movements, and excessive labor intensity of workers.
