Description

Anti-pollution energy-saving type electric bag composite dust collector Technical Field The invention relates to the technical field of electric bag composite dust removal devices, in particular to an energy-saving electric bag composite dust removal device for pollution prevention. Background The electric bag composite dust collector is used as an important special environment protection device, is widely applied to the field of flue gas treatment in the industries of coal-fired power plants, steel, building materials, chemical industry and the like, and has a key effect on controlling atmospheric pollution and reducing industrial dust emission. The typical structure adopts a cooperative working mode of a front electric rear bag, namely dust-containing flue gas firstly enters an electric dust removing area at the front end, dust is charged by utilizing a high-voltage electrostatic field, most of coarse particle dust is directly trapped by an anode plate, and then the charged fine dust enters the bag dust removing area at the rear end, and the dust forms a loose and breathable powder cake layer on the surface of a filter bag due to mutual repulsion of the same charges, so that the running resistance is obviously reduced, the dust removing period is prolonged, the efficient purification is realized, and the method has obvious advantages in deep treatment of atmospheric pollution. However, in the actual operation process, especially when treating the flue gas under the humid working condition, the existing electric bag composite dust collector is used as a special device for protecting the key environment, and the following technical problems exist: Firstly, the dust after being wetted is trapped by the anode plate and is easy to adhere and accumulate in the upper edge area of the electric area ash bucket after being knocked off by vibration. As the run time builds up, the accumulated dust can gradually flood the bottom anode plate and cathode wire. Because the moist dust generally has certain conductivity, when the dust is accumulated to a certain height, a conductive path is formed between the cathode and the anode through accumulated dust, namely, the phenomenon of dust short circuit is generated, so that an electric field is completely invalid, and the atmospheric pollution treatment effect is seriously affected. The traditional electromagnetic vibrator can only perform conventional vibration on the polar plate, and cannot effectively remove dust layers which are accumulated on the upper edge of the ash bucket and are damped. Secondly, in the transition process of the flue gas from the electric dust removing area to the bag dust removing area, the air flow needs to pass through a baffle plate arranged between the electric dust removing area and the bag dust removing area. With existing arrangements, the air flow typically enters the baghouse from a channel at the bottom of the baffle, resulting in local excessive wind velocities in this region. Dust carried by high-speed air flow can directly wash the bottom of the cloth bag, so that abrasion of the bottom of the cloth bag is increased, the service life of the cloth bag is obviously reduced, and the operation and maintenance cost of special equipment for environmental protection is increased. Therefore, the energy-saving type electric bag composite dust collector for pollution prevention is provided. Disclosure of Invention The invention aims to provide an energy-saving electric bag composite dust collector for pollution prevention, which solves the problems that in the prior art, dust short circuit and electric field failure are generated between a cathode and an anode due to the fact that wet dust is easily accumulated on the upper edge of an ash bucket of an electric dust collection area, and the air flow distribution is uneven when flue gas enters a bag dust collection area from the electric dust collection area, high-speed air flow is easy to cause scouring abrasion to the bottom of a bag, and the service life of a filter bag is reduced. The invention provides an energy-saving type electric bag composite dust collector for pollution prevention, which comprises a shell, an electric area ash bucket, an electric dust collection area, a bag dust collection area, a partition board, an electromagnetic vibrator, a disturbance component, a stirring component and a flow equalizing component, wherein the electric dust collection area comprises an anode plate and a cathode wire which are fixedly connected with the top of the shell, the electric area ash bucket is fixedly connected to the bottom of the shell, the electric dust collection area is positioned above the electric area ash bucket, the bag dust collection area is positioned on one side of the electric dust collection area, the partition board is fixedly connected with the shell and is positioned between the electric dust collection area and the bag dust collection area, the electromagnetic vibrator is
