Embodiment 1

[0037] Example 1, such as Figure 1 to Figure 6 shown.

[0038] The dust-collecting electrode blowback filter electrostatic precipitator of the present invention comprises gas inlet 1, housing 2, anode 3, cathode 4, gas outlet 9, ash hopper 10, power supply system 11 etc.; Anode 3 is plate-type dust-collecting electrode (comprising C-shaped plate, Z-shaped plate, etc.), there are multiple anodes 3 along the length direction of the shell 2, and there are multiple rows of anodes 3 along the width direction of the shell 2, and cathodes 4 are arranged between the anodes 3; the high-voltage power supply system supplies the anodes 3 and The cathode 4 supplies power; the anode 3 and the cathode 4 are fixed on the frame of the housing 2 through a hanging device (not shown).

[0039] The anode 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 anode 3 is a mesh dust collection pol...

Embodiment 2

[0044] Example 2, Figure 7shown.

[0045] This embodiment is a change carried out on the basis of Embodiment 1, the difference is:

[0046] In the flow direction of the dusty gas, all the dust collecting poles are mesh dust collecting poles 3.1. In the width direction of the casing 2, there are two rows of mesh dust collecting poles 3.1.

Abstract

The invention belongs to the field of environmental protection and provides an electric dust removal device for dust collecting pole back blowing filter. The device includes a shell, an ash hopper, a gas inlet, a gas outlet, a cathode, an anode, a power supply system, etc. 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; the mesh dust collection pole The poles are arranged in parallel, and are connected with the partitions to form the air intake space of the netted dust collection pole and the air outlet space of the net dust collection pole; the cathode is arranged in the air intake space of the net dust collection pole between the net dust collection poles; There is an injection box, and the injection box is equipped with multiple injection branch pipes and injection valves; there is an injection pipe inside the air outlet space of each mesh dust collector, and each injection pipe has a branch pipe that goes out of the shell and the injection box upwards. connected to the spray pipe. The invention effectively combines electric dust removal and filter dust removal, greatly improves dust removal efficiency; effectively solves the problem of dust removal of mesh dust collection poles; and is suitable for new construction and renovation 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, the dust-containing gas generally needs to go through dust removal facilities to remove a large amount of dust, and the dust content of the gas reaches the national standard. atmospheric emissions. [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 ...
