Embodiment 1

[0043] Example 1, such as Figure 1 to Figure 5 shown.

[0044] The movable dust-collecting pole filter electrostatic precipitator of the present invention includes a gas inlet 1, a housing 2, an anode 3, a cathode 4, a gas outlet 14, an ash hopper 10, a power supply system 11 (not shown), etc., and is characterized in that: The anode 3 constitutes the dust collection pole, and in the direction of the flow of the dust-laden gas, at least a part of the dust collection pole at the rear of the dust collection pole is a mesh dust collection pole 3.1; the net dust collection pole 3.1 is arranged in parallel with the baffles (6, 13, 16) Interconnected to form the air intake space 5 of the mesh dust collector and the air outlet space 7 of the mesh dust collector. 7, flow to the gas outlet 14; the air intake space 5 of the mesh dust collecting pole between the mesh dust collecting poles 3.1 is arranged with the cathode 4; 8 and the filter body 12 etc. of the lower rotating part 9, t...

Embodiment 2

[0053] Example 2, such as Figure 6 ~ Figure 7 shown.

[0054] This embodiment is a change carried out on the basis of Embodiment 1, the difference is:

[0055] 1. In the flow direction of the dusty gas, the dust collection poles are all mesh dust collection poles 3.1.

[0056] 2. Set a brush 19 near the filter body 12 at the lower part of the dust-laden gas mesh dust collection pole 3.1 air intake space 5 to clean the dust on the filter body 12

Abstract

The invention belongs to the field of environment protection and provides a movable electric dust removing device achieving filtration through dust collecting electrodes. The device comprises a gas inlet, a shell, anodes, cathodes, a gas outlet, a dust hopper, a power supply system and the like. In the flowing direction of dusty gas, at least part of the rear portion of each dust collecting electrode is a meshed dust collecting electrode. The meshed dust collecting electrodes are arranged in parallel and connected with baffles to constitute meshed dust collecting electrode gas inlet spaces and meshed dust collecting electrode gas outlet spaces. The cathodes are arranged in the meshed dust collecting electrode gas inlet spaces between the meshed dust collecting electrodes. Each meshed dust collecting electrode comprises an upper rotating part, a lower rotating part, a filtration body annularly surrounding the upper rotating part and the lower rotating part, and the like, wherein the upper rotating part rotates to drive the lower rotating part and the filtration body to rotate. According to the device, electric dust removal and filtration dust removal are combined effectively, and the dust removal efficiency is greatly improved; dust removal of the meshed dust collecting electrodes is effectively achieved through rotation of the filtration bodies; the device is suitable for newly building and transforming projects.

Description

technical field [0001] The invention relates to an industrial flue gas dedusting device and belongs to the field of environmental protection. Background technique [0002] Industrial production in all walks of life produces a large amount of dust-containing gas, and the direct discharge of dust-containing gas into the atmosphere will cause serious environmental pollution. Therefore, dust-containing enterprises generally have to remove a large amount of dust through dust removal facilities. release to the atmosphere. [0003] Dust removal facilities are divided into coarse dust removal facilities and fine dust removal facilities. Fine dust removal facilities mainly include bag filter and electrostatic precipitator. Electrostatic precipitator is widely used because of its small resistance, high dust removal efficiency and temperature resistance. [0004] However, the cost of electrostatic precipitator is high, and the treatment contains dust with high specific resistance (>...
