Description

Technical Field

[0001] This utility model relates to the technical field of wet electrostatic precipitators, specifically to a device for fixing and adjusting the cathode wire counterweight of a wet electrostatic precipitator. Background Art

[0002] Wet electrostatic precipitators utilize the application of tens of thousands of volts of DC high voltage between the anode tube (or plate) and the cathode wire. Under the influence of the strong power field, a corona layer is generated around the corona wire, further ionizing the air and producing a large number of negative ions. When dust (mist) ions in the high-temperature flue gas enter the precipitator, they collide with these positive and negative ions and become charged. The charged dust (mist) particles move towards the anode due to the Coulomb force of the high-voltage electrostatic field. Upon reaching the anode tube (or plate), they release their charge, and the dust (mist) particles are collected by the anode tube (or plate). Simultaneously, the precipitator's internal system uses forward or reverse spraying to form a water film on the anode plate, washing away the collected dust (mist) and separating it from the gas. However, during operation, the cathode wire is prone to deformation and twisting due to the high-temperature flue gas, requiring a cathode wire counterweight for fixation and adjustment.

[0003] The existing patent, CN212633025U, entitled "Wet Electrostatic Precipitator Cathode Wire Counterweight Fixing and Adjusting Device," discloses a wet electrostatic precipitator cathode wire counterweight fixing and adjusting device. This device includes a support device, an adjusting device, a cathode wire, and a counterweight fixer. The adjusting device comprises an upper fixing adjuster and a thermal expansion adjusting limit device. The upper adjusting device includes an L-shaped connecting plate with a second sliding groove on one side. The thermal expansion adjusting limit device includes an L-shaped connecting rod and a fastening ring connected to one end of the L-shaped connecting rod. The cathode wire has a first connecting ring and a second connecting ring fixedly connected to its upper and lower ends, respectively. This invention solves the problem of the cathode wire in a wet electrostatic precipitator easily deforming and deviating from the center of the anode tube under high-temperature flue gas conditions. It ensures that the cathode wire maintains an equal distance from the anode tube wall, allowing dust in the flue gas to be uniformly charged, thus uniformly collecting dust onto the anode plate and improving dust collection efficiency.

[0004] The above-mentioned device solves the problem that the cathode wire of the wet electrostatic precipitator is prone to thermal deformation and deviates from the center of the anode tube under high temperature flue gas environment. However, the adjustable range is small, and it is not easy for a single person to operate when adjusting with two sets of bolts, which cannot well meet people's needs. In view of the above situation, technical innovation is carried out on the basis of the existing weight fixing and adjusting device. Utility Model Content

[0005] The purpose of this invention is to provide a device for fixing and adjusting the cathode wire counterweight of a wet electrostatic precipitator, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cathode wire counterweight fixing and adjusting device for a wet electrostatic precipitator, comprising a cathode wire assembly and a slider.

[0007] Furthermore, the cathode wire assembly includes a cathode wire body and barbs, and the cathode wire body is provided with barbs on its periphery. The barbs improve the current intensity and corona effect, resulting in better dust removal.

[0011] Furthermore, the perimeter of the enclosure is provided with an inner ring, and a spring rod is installed around the outer edge of the inner ring. The inner ring limits the amplitude of the swaying while the spring rod absorbs the impact of the swaying.

[0012] Furthermore, an outer ring is installed around the periphery of the spring rod, and a lower base is installed below the outer ring. The outer ring is stably connected to the ground through the lower base to prevent the entire device from being shaken, impacted, or moved.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the rotating adjustment rod adjusts the position of the moving block in the slide rail of the upper base, adjusts the front and rear position of the slide rod, slides the slider to adjust the left and right position on the slide rod, and uses the fastening knob to fix the slider on the slide rod, which facilitates the adjustment of the position of the cathode wire body in the plane space. The cathode wire body is provided with barbs, which improve the current intensity and corona effect. An appropriate number of counterweights are put on the mounting rod, and then the tray is fixed to the mounting rod with nuts. A suitable counterweight is configured on the connecting plate.
