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

Example Embodiment

[0016] Compare below Figure 1 to Figure 3 Explain that due to the harsh working environment and the relatively high installation position of the dust removal chamber 3, the connection of each component should be checked before the device works, while ensuring that the components are reliably connected to avoid safety accidents. Observe whether the upper dust bag 15 and the lower dust bag 12 are damaged or the thickness of the adhered dust exceeds the limit thickness, and then test run to check whether the pneumatic sequence of each part meets the design requirements, and the device has completed the preparation work.

[0017] When the device is working, compare figure 2 , The dusty gas enters from the dusty gas inlet on the lower right side of the dust removal chamber 3, and then the dusty gas passes through the lower dust removal bag 12 to complete the first dust removal process, and the dusty gas continues to rise under the action of the air pressure until it enters the dust r...

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...
