Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and particularly relates to an electrostatic treatment device for waste gas. Background Technique

[0002] Waste gas refers to the toxic and harmful gases discharged by humans in the production and living processes. Especially chemical plants, steel plants, pharmaceutical plants, coking plants, oil refineries, etc., emit waste gas with a strong smell, which seriously pollutes the environment and affects human health.

[0003] At present, the electrostatic treatment device for waste gas uses a strong electric field generated by a high-voltage DC power supply to ionize the gas, generate corona discharge, and then charge the suspended dust particles. Under the action of the electric field force, the suspended dust particles are separated from the gas and captured to achieve dust removal. The shedding of dust is generally realized by vibrating the anode and cathode. The vibration process is prone to dislocation, and the stability needs to be improved. Secondly, there is no pre-treatment effect before treatment. A large amount of dust easily leads to too high a maintenance frequency and affects the service life.

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] AsFigures 1-4 As shown in the figure, an electrostatic treatment device for waste gas includes: a cyclone chamber 1, a soot conveying channel 11 is arranged on the outer wall of the cyclone chamber 1, a flushing chamber 2 is arranged at the top of the cyclone chamber 1, an output pipe 24 is arranged on the outer wall of the flushing chamber 2, one end of the output pipe 24 is provided with an electrostatic treatment chamber 4, and a plurality of metal plates 45 are slidably matched in the electrostatic treatment chamber 4, and metal guide rods 46 are arranged between adjacent metal plates 45.

[0031] Among them, an exhaust channel 42 is arranged on the outer wall of the electrostatic treatment chamber 4.

[0032] Among them, a driving motor 3 is arranged at the top of the flushing chamber 2, a transmission rod 31 is arranged at the output end of the driving motor 3, the transmission rod 31 extends downward into the cyclone chamber 1, a spiral fan blade 32 is arranged at the end of the transmission rod 31, a housing cover 33 is arranged outside the spiral fan blade 32, and a convex rib 12 is arranged in the cyclone chamber 1, and the housing cover 33 is located on the convex rib 12.

[0033] Among them, the flushing chamber 2 includes a first bottom plate 21, a conveying pipe 22 is arranged between the flushing chamber 2 and the first bottom plate 21, a first spray head 23 for downward spraying is arranged on the conveying pipe 22, and the input end of the conveying pipe 22 extends outward through the flushing chamber 2.

[0034] Furthermore, the flushing chamber 2 and the first bottom plate 21 have good assembly performance, which is beneficial to the maintenance of the first spray head 23 and the spiral fan blade 32.

[0035] Furthermore, during the process of the driving motor 3 driving the spiral fan blade 32 as a power source, the waste gas is converged to improve the flow effect, and the downward spraying first spray head 23 can reduce the dust content in the waste gas, which is beneficial to the subsequent electrostatic treatment effect.

[0036] Such as Figures 5-7 As shown in the figure, the electrostatic treatment chamber 4 includes a second bottom plate 41, a sewage discharge pipe 47 is arranged at the bottom of the second bottom plate 41, a valve body 48 is arranged on the sewage discharge pipe 47, a drain pipe is arranged at the bottom of the cyclone chamber 1, and the drain pipe is fixedly matched with the sewage discharge pipe 47.

[0037] Among them, a limiting strip 43 is arranged on the inner wall of the electrostatic treatment chamber 4, a sliding groove 44 is arranged on the limiting strip 43, and the metal plate 45 is slidably matched in the sliding groove 44.

[0038] Among them, a plurality of second spray heads 5 for upward spraying are arranged on the second bottom plate 41, a connecting pipe 51 is arranged at the bottom of the second bottom plate 41 corresponding to the second spray heads 5, and the second spray heads 5 are connected in cooperation through the connecting pipe 51 with adjacent second spray heads 5.

[0039] Furthermore, the electrostatic treatment chamber 4 and the second bottom plate 41 have good assembly performance, which is beneficial to the maintenance of the metal plate 45, the metal guide rod 46 and the second spray head 5.

[0040] Furthermore, the metal plate 45 serves as the anode, while the metal conducting rod 46 serves as the cathode. A high-voltage direct current is passed through the metal conducting rod 46, which can maintain an electrostatic field sufficient to ionize the gas. The charged dust moves towards the electrode opposite to its own under the action of the electric field force and deposits on the electrode, thus achieving adsorption.

[0041] The working principle is as follows: The waste gas is discharged into the swirling chamber 1 through the soot conveying channel 11. The movement of the spiral fan blades 32 in the swirling chamber 1 can lift the waste gas and accelerate its entry into the flushing chamber 2. At the same time, multiple first spray nozzles 23 spraying downward in the flushing chamber 2 can reduce the dust content in the waste gas. As the air flow moves, the treated waste gas will flow into the electrostatic treatment chamber 4 through the output pipe 24. Since a high-voltage direct current is passed through the metal conducting rod, a combined action with the metal plate 45 will form an electrostatic field sufficient to ionize the gas. The dust moves towards the electrode opposite to its own under the action of the electric field force and deposits on the electrode to achieve adsorption.

[0042] During dust cleaning, the metal conducting rod 46 is in a power-off state. Subsequently, the second spray nozzle 5 sprays upward to wash down the dust adsorbed on the metal plate 45 and the metal conducting rod 46, and the dust-containing liquid will be discharged through the sewage pipe 47.
