Technical Field

[0001] The invention relates to the technical field of tail gas treatment, in particular to an adsorption recovery device for tail gas containing trichloroethylene. Background Art

[0002] The trichloroethylene tail gas treatment system is an equipment system used to treat trichloroethylene (C2H3Cl3) tail gas generated in industrial production processes. Trichloroethylene is an organic compound commonly used in industrial fields such as solvents, plastic manufacturing and cleaning agents. Due to its volatility and potential environmental and health risks, effective treatment is required to ensure the safety of the environment and human health.

[0003] According to an organic waste gas purification adsorption recovery device proposed in Chinese patent CN221385815U, the device can filter the waste gas before it enters the purification tank through the combination of filter plates, fans, cover plates, mounting boxes, slide grooves, card plates, pull rods, springs and other structures, thereby removing large particulate matter, acid mist and alkaline mist, etc., which helps to protect the purification equipment from corrosion and blockage and improves practicality.

[0004] There are some shortcomings in the device. In the process of filtering the exhaust gas through the filter plate, since there are some larger particles in the exhaust gas, some large particles are likely to clog the mesh of the filter plate, making it impossible for the filter plate to filter the large particles in the exhaust gas, affecting the treatment effect of the device on the exhaust gas. For this reason, we proposed an adsorption and recovery device for exhaust gas containing trichloroethylene tail gas. Summary of the invention

The bottom of the cleaning brush is slidably connected to the top of the first filter plate. By setting the filtering component, when the trichloroethylene waste gas needs to be recovered and processed, the operator turns on the fan to cause the fan to absorb the trichloroethylene waste gas into the interior of the processing barrel through the gas collecting pipe, and then turns on the motor to cause the output shaft to rotate. After the output shaft rotates, it will rotate with the first filter plate. During the rotation of the first filter plate, it is easy to filter the solid particles in the trichloroethylene waste gas.

This process is repeated to facilitate filtering the trichloroethylene waste gas. Solid particles in the trichloroethylene waste gas block the mesh of the second filter plate, affecting the filtering effect. After the second filter plate moves downward, the connecting column is compressed.

After the output shaft rotates, it will drive the first filter plate to rotate. During the rotation of the first filter plate, it is convenient to filter the solid particles in the trichloroethylene waste gas. During the rotation of the output shaft, the first bevel gear and the second bevel gear will be meshed to cause the transmission shaft to rotate, thereby causing the cleaning brush to rotate and clean the surface of the first filter plate during the rotation, thereby preventing the solid particles in the trichloroethylene waste gas from clogging the mesh of the first filter plate and affecting the filtering effect of the trichloroethylene waste gas. During the filtering of the trichloroethylene waste gas, the operator turns on the water pump to cause the water in the water tank to be discharged from the spray head through the drain pipe, thereby filtering the trichloroethylene in the processing barrel.

When the trichloroethylene waste gas enters the purification box, the trichloroethylene waste gas will first pass through the purification layer, thereby achieving preliminary purification of the trichloroethylene waste gas, and then pass through the activated carbon adsorption layer to adsorb the odor in the trichloroethylene waste gas. Then the trichloroethylene waste gas passes through the filter layer to further filter the trichloroethylene waste gas. Then the trichloroethylene waste gas passes through the deodorization layer to blow the trichloroethylene waste gas.

[0027] The filter assembly 41 also includes a water tank 4122 fixedly connected to the top of the treatment barrel 2, and the side wall of the water tank 4122 is fixedly connected to a water pump 4123.

A drain port 4126 is provided at the bottom of the treatment barrel 2, and a first valve 4127 is fixedly connected to the outer wall of the drain port 4126. In the process of filtering the trichloroethylene waste gas, the operator turns on the water pump 4123 to cause the water in the water tank 4122 to be discharged from the spray head 4125 through the drain pipe 4124, so as to clean the trichloroethylene waste gas in the treatment barrel 2. By setting the drain port 4126 and the first valve 4127, after the cleaning of the trichloroethylene waste gas is completed, the operator opens the first valve 4127 to facilitate the discharge of waste water from the drain port 4126.

When the first filter plate 415 rotates, the first semicircular block 4111 at the bottom thereof squeezes the second semicircular block 4112, prompting the second filter plate 4113 to move downward and compress the first spring 4114. This process is repeated to facilitate filtering the trichloroethylene waste gas. The solid particles in the trichloroethylene waste gas block the mesh of the second filter plate 4113, affecting the filtering effect. After that, the connecting column 4116 will be compressed.

[0029] A preferred embodiment of the trichloroethylene tail gas adsorption recovery device provided by the present invention is as follows: Figures 1 to 7As shown: the outer wall of the treatment barrel 2 is connected to a purification component 42, and the purification component 42 also includes an exhaust pipe 421 connected to the top outer wall of the treatment barrel 2, and the middle outer wall of the exhaust pipe 421 is fixedly connected to a second valve 422, and the other end of the exhaust pipe 421 is connected to a purification box 423, and the bottom of the purification box 423 is fixedly connected to a support plate 4211, and the other side of the support plate 4211 is fixedly connected to the outer wall of the treatment barrel 2, and the top of the inner wall of the purification box 423 is fixedly connected to a condenser 424, and the middle inner wall of the purification box 423 is fixedly connected to a purification layer 425, and the bottom of the purification layer 425 is fixedly connected to an activated carbon adsorption layer 426, and the bottom of the activated carbon adsorption layer 426 is fixedly connected to a filter layer 427, and the bottom of the filter layer 427 is fixedly connected to a deodorizing layer 428, and the outer wall of the purification box 423 is connected to a drain pipe 429, and the middle outer wall of the drain pipe 429 is fixedly connected to a third valve 4210. By setting the purification component Component 42, after the trichloroethylene waste gas is filtered, the operator opens the second valve 422 to allow the cleaned trichloroethylene waste gas to be discharged into the purification box 423 through the exhaust pipe 421. When the trichloroethylene waste gas enters the purification box 423, the trichloroethylene waste gas will first pass through the purification layer 425, thereby achieving preliminary purification of the trichloroethylene waste gas, and then pass through the activated carbon adsorption layer 426, through which the odor in the trichloroethylene waste gas is adsorbed. Then the trichloroethylene waste gas passes through the filter layer 427 to further filter the trichloroethylene waste gas, and then the trichloroethylene waste gas passes through the deodorization layer 428 to blow the trichloroethylene waste gas. After the trichloroethylene waste gas is purified, the operator opens the condenser 424 to condense the trichloroethylene gas into liquid, and opens the third valve 4210 to discharge the liquid from the drain pipe 429.

[0030] Furthermore, a support leg 3 is fixedly connected to the bottom of the fixing ring 1. There are four support legs 3, which are distributed in a circular array along the central axis of the fixing ring 1. By providing four support legs 3, it is convenient to provide stable support for the device.

[0031] Furthermore, the first filter plate 415 and the second filter plate 4113 are of equal size, and the bottom of the first filter plate 415 is fixedly connected to the top of the first semicircular block 4111. By arranging the first filter plate 415 and the second filter plate 4113, secondary filtration of solid particles in trichloroethylene waste gas is facilitated.

[0032] Furthermore, there are four support blocks 4115 , which are equal in size and are distributed in a circular array along the central axis of the second filter plate 4113 .

[0033] In addition, the bottom inner wall of the slider 4118 is matched with the outer wall of the limiting column 4120 , and the outer wall of the slider 4118 is matched with the inner wall of the rectangular block 4119 .

[0034] Working principle: When it is necessary to recycle the trichloroethylene waste gas, the operator turns on the fan 412 to cause the fan 412 to absorb the trichloroethylene waste gas into the inside of the treatment barrel 2 through the gas collecting pipe 411, and then turns on the motor 413 to cause the output shaft 414 to rotate. After the output shaft 414 rotates, it will drive the first filter plate 415 to rotate. During the rotation of the first filter plate 415, it is convenient to filter the solid particles in the trichloroethylene waste gas. During the rotation of the output shaft 414, the first bevel gear 416 and the second bevel gear 417 are meshed to cause the transmission shaft 418 to rotate, thereby causing the cleaning brush 4110 to rotate and clean the surface of the first filter plate 415 during the rotation, thereby preventing the solid particles in the trichloroethylene waste gas from clogging the mesh of the first filter plate 415 and affecting the filtering effect of the trichloroethylene waste gas.

[0035] In the process of filtering the trichloroethylene waste gas, the operator starts the water pump 4123 to cause the water in the water tank 4122 to be discharged from the spray head 4125 through the drain pipe 4124, so as to clean the trichloroethylene waste gas in the treatment barrel 2. By setting the drain port 4126 and the first valve 4127, after the cleaning of the trichloroethylene waste gas is completed, the operator opens the first valve 4127 to facilitate the discharge of waste water from the drain port 4126.

[0036] When the first filter plate 415 rotates, the first semicircular block 4111 at the bottom thereof squeezes the second semicircular block 4112, prompting the second filter plate 4113 to move downward and compress the first spring 4114. This process is repeated to facilitate the solid particles in the trichloroethylene waste gas to block the mesh of the second filter plate 4113 when filtering the trichloroethylene waste gas, affecting the filtering effect. After the second filter plate 4113 moves downward, it compresses the connecting column 4116. When the connecting column 4116 moves downward, it squeezes the toggle plate 4117 under the action of the hinge, prompting the toggle plate 4117 to rotate and causing the slider 4118 to slide on the outer wall of the limiting column 4120, so that in the process of prompting water to clean the trichloroethylene waste gas, the toggle plate 4117 rotates to toggle the water, thereby improving the cleaning effect of the trichloroethylene waste gas, thereby cleaning out the impurities in the trichloroethylene waste gas and improving the treatment effect of the trichloroethylene waste gas;

[0037] After the trichloroethylene waste gas is filtered, the operator opens the second valve 422 to allow the cleaned trichloroethylene waste gas to be discharged into the purification box 423 through the exhaust pipe 421. When the trichloroethylene waste gas enters the purification box 423, the trichloroethylene waste gas will first pass through the purification layer 425, thereby achieving preliminary purification of the trichloroethylene waste gas, and then pass through the activated carbon adsorption layer 426 to adsorb the odor in the trichloroethylene waste gas. Then the trichloroethylene waste gas passes through the filter layer 427 to further filter the trichloroethylene waste gas, and then the trichloroethylene waste gas passes through the deodorization layer 428 to deodorize the trichloroethylene waste gas. After the trichloroethylene waste gas is purified, the operator opens the condenser 424 to condense the trichloroethylene gas into liquid, and opens the third valve 4210 to discharge the liquid from the drain pipe 429, thereby improving the treatment effect of the trichloroethylene waste gas.
