Embodiment 1

[0032] figure 1 Among them, the dry-wet hybrid electrostatic precipitator is mainly composed of an inlet smoke box 1, an air flow uniform distribution plate 2, a shell 5, an outlet smoke box 9, an outlet groove plate 10, a rapping device 12, an ash hopper 11, a water distribution device, and a collector. The water tank is composed of 14, and it is characterized in that there are several electric fields upstream in the direction of flue gas or waste gas inflow, except that the last electric field is a wet cleaning electric field using wet water film cleaning, and the rest of the electric fields use mechanical vibration and electromagnetic vibration. The dry-type ash-clearing electric field for beating or sonic cleaning, the dry-type ash-cleaning electric field and the wet-type ash-cleaning electric field are arranged in the same housing 5, and the wet-type ash-cleaning electric field is connected with the ash-cleaning water treatment and recycling system.

Abstract

The invention relates to a wet-dry mixing electric dust remover. The electric dust remover mainly consists of an inlet smoke box, an air flow uniformly-distributing plate, a shell, a cathode line, an anode plate, an outlet smoke box, an outlet trough-shape plate, a rapping device, an ash bucket, a water distribution device and a water tank. The electric dust remover is characterized in that the upstream in the inflow direction of the smoke gas or the exhaust gas is provided with a dry-type ash removal electric field which adopts mechanical rapping, electromagnetic rapping or acoustic wave to remove the ash, the last electric field is a wet-type ash removal electric field which adopts a water film to remove the ash, the dry-type ash removal electric field and the wet-type ash removal electric field are arranged in the same shell, and the wet-type ash removal electric field is connected with an ash removal water treatment recycling system. The invention integrates the advantages of the dry-type electric dust removal and the wet-type electric dust removal, efficiently removes dust, ensures emission standards and minimizes the corrosion protection investment caused by the wet-type ash removal, the water treatment equipment investment and the running cost.

Description

technical field [0001] The invention belongs to the field of flue gas purification for environmental protection, and in particular relates to a high-voltage electrostatic dry-wet hybrid electrostatic precipitator which combines dry and wet ash removal. Background technique [0002] Dry electrostatic precipitator is currently the most widely used and most important method of dust removal. It is widely used in electric power, metallurgy, building materials and other industries for flue gas dust removal. It has the advantages of large amount of flue gas treatment, high dust removal efficiency, small resistance, simple process Advantages of low maintenance costs. However, the dry electrostatic precipitator has poor adaptability to the specific resistance of smoke (dust), and back corona occurs when collecting high specific resistance smoke (dust), which seriously affects the operation of electrostatic precipitator and reduces the efficiency of dust removal. When collecting low ...
