Technical Field

[0001] The invention relates to the technical field of air treatment, and in particular to a VOC waste gas odor treatment device. Background Art

[0002] With the surging tide of global industrialization, volatile organic compounds (VOCs) released during industrial production have become an environmental pollution source that cannot be ignored. These VOCs not only affect the quality of life of residents due to their unique irritating odor, but also because of their complex chemical properties, they can participate in atmospheric chemical reactions, leading to global environmental problems such as photochemical smog and ozone layer depletion. In addition, long-term exposure to VOC environments can also cause harm to human health, such as respiratory diseases and nervous system damage. Common VOC treatment methods include adsorption, absorption, condensation and combustion. Among them, the existing adsorption method directly adsorbs VOC waste gas, and the dust in the waste gas will also be adsorbed onto the adsorption plate, causing the adsorption plate to be blocked and affecting its service life. Summary of the invention

[0003] The invention aims to solve the technical problem of how to remove dust from VOC waste gas, and proposes a VOC waste gas odor control device. The technical solution of the invention is as follows: A VOC waste gas odor control device includes: a base, a wet dust removal device, a gas collection device, and an activated carbon adsorption device. The wet dust removal device is arranged above the base and fixedly connected to the upper surface of the base. The gas collection device is arranged above the wet dust removal device and connected to the wet dust removal device. The activated carbon adsorption device is arranged above the base and on the side of the wet dust removal device. The activated carbon adsorption device is fixedly connected to the upper surface of the base and connected to the wet dust removal device.

[0004] When VOC waste gas needs to be treated, the staff turns on the gas collection device and the wet dust removal device. The gas collection device sucks the waste gas into the wet dust removal device, which removes the dust from the waste gas. The waste gas then enters the adsorption device, which removes the volatile substances in the waste gas, thereby eliminating the odor in the waste gas. After that, the waste gas flows out of the adsorption device and enters the next step. When the wet dust removal device is working, it will drive the gas collection device to reciprocate, thereby absorbing a larger area of ​​waste gas. At the same time, the wet dust removal device will drive the adsorption device to work, accelerating the efficiency of waste gas adsorption.

[0005] Furthermore, the wet dust removal device includes: a collection box, a filter plate, a square tube, a dust removal cylinder, a motor, a first rotating rod, a stirring blade, an air pump, a water storage chamber, and an electric nozzle.

[0046] When the first rotating rod 207 rotates, the rotation of the first rotating rod 207 drives the incomplete gear 409 to rotate, and the rotation of the incomplete gear 409 will drive the second rack 411 to move up and down, and the up and down movement of the second rack 411 drives the second connecting rod 412 to move up and down, and the up and down movement of the second connecting rod 412 drives the third connecting rod 413 to move up and down, and the up and down movement of the third connecting rod 413 drives the third rack 414 to move up and down, and the third rack 414 moves down and drives the second gear 415 to rotate back and forth, and the reciprocating rotation of the second gear 415 drives the threaded rod 405 to rotate back and forth, and the reciprocating rotation of the threaded rod 405 drives the sliding sleeve 406 to move left and right, and the left and right movement of the sliding sleeve 406 drives the adsorption plate 407 to move left and right, and the left and right movement of the adsorption plate 407 will accelerate the adsorption of exhaust gas and increase work efficiency.

[0047] The material of the adsorption plate 407 is activated carbon.

[0048] Activated carbon can treat many types of VOC exhaust gases.

[0049] The inner wall of the adsorption cylinder 402 is provided with a polyurethane anti-corrosion coating.

[0050] The polyurethane anti-corrosion coating can prevent volatile gases from corroding the adsorption tube 402 and increase its service life.

[0051] Working principle: When it is necessary to treat VOC waste gas, the staff turns on the fan 305, the electric nozzle 211 and the motor 206. After the staff turns on the fan 305, the fan 305 forms a negative pressure to suck the waste gas into the conical cylinder 304. After the waste gas enters the conical cylinder 304, it enters the dust removal cylinder 205 through the air intake pipe 306. After the waste gas enters the dust removal cylinder 205, the electric nozzle 211 converts the water in the water storage chamber 210 into water mist and sprays it into the dust removal cylinder 205 to reduce the dust of the waste gas in the dust removal cylinder 205.

[0052] When the staff turns on the motor 206, the motor 206 rotates to drive the first rotating rod 207, and the first rotating rod 207 rotates to drive the stirring blade 208 to rotate. The stirring blade 208 rotates to make the exhaust gas and the water mist fully contact. After the dust in the exhaust gas contacts the water mist, under the action of gravity, it enters the collection box 201 through the square tube 204, where the dust will fall onto the filter plate 202, and the sewage will fall into the collection box 201 through the filter plate 202, thereby removing the dust in the exhaust gas. The exhaust gas with dust removed enters the adsorption cylinder 402 through the connecting pipe 403 under the action of the vacuum pump 209, and the exhaust gas passes through the adsorption plate 407. The volatile substances in the exhaust gas are adsorbed by the adsorption plate 407, thereby removing the odor in the exhaust gas, and then enters the next process through the exhaust pipe 404.

[0053] When the first rotating rod 207 rotates, the first rotating rod 207 drives the first bevel gear 310 to rotate, the first bevel gear 310 rotates to drive the second bevel gear 311 to rotate, the second bevel gear 311 rotates to drive the second connecting rod 412 to rotate, the second connecting rod 412 rotates to drive the first curved rod 312 to rotate, the first curved rod 312 rotates to drive the second curved rod 313 to rotate, the second curved rod 313 rotates to drive the sliding block 314 to move left and right, the sliding block 314 moves left and right to drive the first rack 315 to move left and right, the second rack 411 moves left and right to drive the first gear 316 to reciprocate, the reciprocating rotation of the first gear 316 drives the second gear to reciprocate, the reciprocating rotation of the second rotating rod 302 drives the rotating disk 303 to reciprocate, the reciprocating rotation of the rotating disk 303 drives the conical cylinder 304 to reciprocate, the reciprocating rotation of the conical cylinder 304 drives the fan 305 to reciprocate, thereby increasing the area for absorbing exhaust gas.

[0054] When the first rotating rod 207 rotates, the rotation of the first rotating rod 207 drives the incomplete gear 409 to rotate, and the rotation of the incomplete gear 409 will drive the second rack 411 to move up and down, and the up and down movement of the second rack 411 drives the second connecting rod 412 to move up and down, and the up and down movement of the second connecting rod 412 drives the third connecting rod 413 to move up and down, and the up and down movement of the third connecting rod 413 drives the third rack 414 to move up and down, and the third rack 414 moves down and drives the second gear 415 to rotate back and forth, and the reciprocating rotation of the second gear 415 drives the threaded rod 405 to rotate back and forth, and the reciprocating rotation of the threaded rod 405 drives the sliding sleeve 406 to move left and right, and the left and right movement of the sliding sleeve 406 drives the adsorption plate 407 to move left and right, and the left and right movement of the adsorption plate 407 will accelerate the adsorption of exhaust gas and increase work efficiency.
