Example Embodiment

[0037] Example 1, such as Figure 1 ~ Figure 6 Shown.

[0038] The dust collecting electrode backflushing and filtering electric dust removal device of the present invention includes a gas inlet 1, a shell 2, an anode 3, a cathode 4, a gas outlet 9, a ash hopper 10, a power supply system 11, etc.; the anode 3 is a plate type dust collecting electrode (including C-shaped plate, Z-shaped plate, etc.), there are multiple anodes 3 along the length of the casing 2, and multiple rows of anodes 3 along the width of the casing 2. The cathode 4 is arranged between the anodes 3; The cathode 4 is powered; the anode 3 and the cathode 4 are fixed on the frame of the housing 2 by a hanging device (not shown).

[0039] The anode constitutes a dust collecting electrode. In the direction of the flow of dust-containing gas, at least a part of the dust collecting electrode at the rear of the anode 3 is a mesh dust collecting electrode 3.1; the mesh dust collecting electrode 3.1 is arranged in parall...

Example Embodiment

[0044] Example 2, Figure 7 Shown.

[0045] This embodiment is a change made on the basis of Embodiment 1. The differences are:

[0046] In the direction of the dust-containing gas flow, all the dust collecting electrodes are mesh dust collecting electrodes 3.1. In the width direction of the housing 2, the mesh dust collecting electrodes 3.1 are in two rows.

Abstract

The invention belongs to the field of environmental protection, and provides a dust collection electrode back-flushing filtering electrostatic precipitator. The electrostatic precipitator comprises a housing, dust buckets, an air inlet, an air outlet, negative electrodes, positive electrodes, a power supply system, and the like. In a dust-contained air flowing direction, at least a part of dust collection electrodes at the rear part of the dust collection electrodes are meshy dust collection electrodes; the meshy dust collection electrodes are arranged in parallel and are connected to separators to form meshy dust collection electrode air-intake spaces and meshy dust collection electrode air-exhaust spaces; and the negative electrodes are arranged in the meshy dust collection electrode air-intake spaces among the meshy dust collection electrodes. An injection box is arranged outside the housing, and is provided with a plurality of injection branch pipes and injection valves; each meshy dust collection electrode air-exhaust space is internally provided with one injection pipe; and each injection pipe having a branch pipe extending upwards out of the housing and connecting the injection branch pipes of the injection box. According to the invention, electric precipitation is effectively combined with filtering precipitation, so that the dust removing efficiency is greatly improved; the problem of dust cleaning of meshy dust collection electrodes is effectively solved; and the dust collection electrode back-flushing filtering electrostatic precipitator is suitable for reconstruction and renovation of a project.

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 ...
