Rapping rod applied to high-concentration electrostatic dust collector

Abstract

The invention relates to a rapping rod applied to a high-concentration electrostatic dust collector. The rapping rod comprises a rapping anvil and rapping angle steel; the rapping anvil is made of No.35 steel materials; a groove is formed in the lower portion of the head of the rapping anvil; a positioning reinforcing rib plate is arranged at the contact position of the rapping angle steel and the rapping anvil; and the rapping anvil is connected with the rapping angle steel through a torque type bolt. The rapping rod has the beneficial effects that the requirement of the high-concentration electrostatic dust collector for the frequent rapping working condition can be met; compared with an existing rapping rod structure, the rapping rod is simple in structure, convenient to manufacture and mount, low in cost and considerable in benefit.

Description

technical field [0001] The invention relates to an electrostatic precipitator, in particular to a rapping rod in the electrostatic precipitator. Background technique [0002] The electrostatic precipitator uses multiple sets of cathode and anode electrodes installed in the high-voltage electric field to charge the dust in the flue gas. Most of the dust is gradually deposited on the surface of the anode plate, and the anode rapping system drives the rapping hammer to hit the bottom of the anode plate. The rapping rod knocks down the ash accumulated on the surface of the anode plate and falls into the ash hopper, so that the dust and the flue gas are separated to achieve the purpose of purifying the flue gas. However, the imported dust concentration of high-concentration electrostatic precipitators is generally very high, up to 90g / Nm 3 Left and right, so the frequency of rapping and cleaning is very high. At the same time, heavy hammers are also used for rapping, which has a...

Problems solved by technology

[0003] like figure 1 , figure 2 As shown, the rapping angle steel 2 is connected with the rapping anvil 1 made of Q235 steel using Hooke rivets 3; the above-mentioned structure often causes the rapping anvil to fall off, which leads to the blockage of the ash conveying system at the bottom of the dust collector, resulting in an electric field Short circuit, the efficiency of the electrostatic precipitator is greatly reduced, and it must be shut down for maintenance, which affects the operation of the entire system, and also increases the cost of maintenance and spare parts
