Description

Technical Field

[0001] This utility model relates to the technical field of electrostatic precipitators, and in particular to the technical field of anode rapping devices. Background Technology

[0002] In practical applications of dust collectors, as the dust particles in the flue gas move further into the rear electric field, the particle size gradually decreases and the dust stickiness relatively increases. If the dust is cleaned solely by the bottom anode rapping device, the transmission of the rapping force gradually decreases, making it difficult to remove the dust accumulated in the upper part of the rear electric field.

[0003] Patent document CN222306069U discloses a multi-layer rapping device for high anode plates in electrostatic precipitators. This device adds a central rapping device, which improves the dust removal effect. In the prior art, the installation structure of the central rapping device is the same as that of the bottom rapping device. In order to install the central rapping device, it is necessary to make holes in the anode plate for installation. Therefore, it is necessary to change the anode plate model, which is very troublesome. Moreover, the hole-making installation method is inconvenient for daily maintenance. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a rapping device for the anode center of an electrostatic precipitator, which can solve the above problems.

[0005] To achieve the above objectives, this utility model proposes a central rapping device for the anode of an electrostatic precipitator, comprising an anode plate unit, a bottom rapping device at the bottom of the anode plate unit, and a central rapping device at the upper middle part of the anode plate unit. The anode plate unit includes several parallel anode plate groups arranged parallel to the flue gas direction. Several cathode wires are provided between adjacent anode plate groups. Each anode plate group is composed of several anode plate bodies, with gaps between adjacent anode plate bodies. The central rapping device includes a central rapping rod arranged parallel to the flue gas direction. The central rapping rod includes two side plates located on both sides of the anode plate group, connected by a connecting device that passes through the gap. A central rapping block is provided at the end of each side plate, and a central rapping hammer assembly is provided at the central rapping block. Positioning angle steels are provided at both ends of the anode plate unit, perpendicular to the flue gas direction, and the two positioning angle steels are installed on both sides of the bottom of the central rapping rod.

[0006] Preferably, the connecting device is a bolt assembly.

[0007] Preferably, the top plate of the positioning angle steel abuts against the bottom of the central vibrating rod, and the side of the positioning angle steel abuts against the outer side of the main body of the anode plate at the end of each row.

[0008] Preferably, the bottom rapping device includes two mounting plates located on both sides of the anode plate assembly, which are connected by a connecting component. The anode plate body has mounting holes through which the connecting component passes. Bottom rapping blocks are installed at the ends of the two mounting plates, and bottom rapping hammer assemblies are provided at the bottom rapping blocks.

[0009] Preferably, the anode plate body is a conventional C-type anode plate.

[0010] The beneficial effects of this utility model are as follows: The anode center rapping device of this utility model is fixed and limited by positioning angle steel and conventional anode plate, and the connecting device passes through the gap between the anode plates for reinforcement connection. This installation structure facilitates daily maintenance and does not require changing the anode plate type during modification projects, making installation and modification more convenient.

[0011] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description
