DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application is further described below in combination with specific embodiments.

[0032] Embodiment one, please refer to Figure 1 and Figure 2 As shown in the figure, a kind of waste gas treatment device for adhesive tape production workshop, including air inlet 1, air inlet 1 right side fixedly connected with processing assembly one 2, processing assembly one 2 right side fixedly connected with processing assembly two 3, processing assembly two 3 rear fixedly connected with purification assembly 4, purification assembly 4 left side fixedly connected with desorption assembly 5, desorption assembly 5 front end fixedly connected with air pumping assembly 6.

[0033] In the implementation process of the scheme, first, the operator needs to connect the air inlet 1 with the exhaust gas extraction device of the adhesive tape production workshop, then adjust the parameters of the internal components of the treatment assembly one 2 according to the implementation situation, further, the components inside the treatment assembly one 2 will treat the exhaust gas entering from the air inlet 1, so that the exhaust gas rises in a spiral form, and then is wet treated by cooperating with the internal spraying device, so that the particles in the exhaust gas fall into the inner cavity of the treatment assembly one 2. The gas rising in a spiral form will finally be discharged into the inner cavity of the treatment assembly two 3 from the pipeline fixedly connected to the upper part of the treatment assembly one 2, then the treatment assembly two 3 will dry treat the exhaust gas from the treatment assembly one 2, further, after the treatment assembly two 3 dry separates the wet treated exhaust gas, the exhaust gas will enter the inner cavity of the purification assembly 4 through the pipeline on the right side of the treatment assembly two 3, then the adsorption material installed in the inner cavity of the purification assembly 4 will adsorb the harmful gas in the exhaust gas, and the adsorbed gas will be discharged into the atmosphere, further, when the adsorption material in the inner cavity of the purification assembly 4 reaches the saturation state, the electromagnetic valves installed at the bottom and the upper part of the purification assembly 4 will be closed, so that the purification assembly 4 is in a sealed state. At this time, the air extraction assembly 6 will extract the air from the bottom of the inner cavity of the purification assembly 4, and then transport the extracted air to the inner cavity of the desorption assembly 5, then the air in the inner cavity of the purification assembly 4 is desulfurized, and then after heating by the desorption assembly 5, the catalyst in the internal components of the desorption assembly 5 will be released, and then enters the inner cavity of the purification assembly 4 together with the heated gas, then the adsorption material is backwashed at the same time, so that it has adsorption capacity again.

[0034] Further, through the cooperation of the treatment assembly one 2 and the treatment assembly two 3, and the synergistic effect of the adsorption and desorption assembly 5, the efficient removal of particulate matter and harmful gas in the exhaust gas is realized. The treatment assembly one 2 can effectively remove particulate matter in the exhaust gas, and the treatment assembly two 3 can further remove impurities in the exhaust gas. The adsorption material can adsorb harmful substances in the exhaust gas during the purification process. When the adsorption material reaches saturation, the heating and backwashing technology of the desorption assembly 5 can restore its adsorption capacity and prolong its service life, reduce labor cost and filter core material.

[0035] Further, the electromagnetic valve mentioned above is a very mature existing technology in the prior art. In the scheme, only its function of being controlled by the control end to open and close is used, and the working principle is not described in detail.

[0036] Please refer to Figure 3 and Figure 4 and Figure 5As shown, the processing assembly 1 2 includes a shell 1 21, the inner cavity of the shell 1 21 is fixedly connected with a filter plate 1 22 in the middle, the front side of the shell 1 21 is fixedly connected with a pumping assembly 23, the right side of the shell 1 21 is fixedly connected with a control console 24, the upper end of the shell 1 21 is fixedly connected with a shell 2 25, the upper end of the shell 2 25 is fixedly connected with a connecting pipe 1 26, the front side of the shell 1 21 is fixedly connected with a transmission assembly 27, the pumping assembly 23 includes a water suction pipe 231, the water suction pipe 231 is fixedly connected with the front bottom of the shell 1 21, the upper end of the water suction pipe 231 is fixedly connected with a water pump 232, the output end of the water pump 232 is fixedly connected with a converging cavity 233, the upper end of the converging cavity 233 is fixedly connected with three delivery pipes 234, the other ends of the three delivery pipes 234 are all fixedly connected with a spraying assembly 235, the spraying assembly 235 includes a fixed plate 2351, the fixed plate 2351 is fixedly connected with a communication rack 2352 in the middle, the communication rack 2352 is provided with a water sprayer at the bottom, the communication rack 2352 is fixedly connected with a communication pipe 1 2353 at the bottom, the communication pipe 1 2353 is rotatably connected with a spray head 2354 at the bottom, the outer surface of the spray head 2354 is rotatably connected with a support rack 2355 at the bottom, the outer surface of the spray head 2354 is fixedly connected with a cyclone plate 2356 on the side away from the support rack 2355 at the bottom, the transmission assembly 27 includes a motor 271, the motor 271 is fixedly connected with a transmission wheel 272 through a shaft coupling at the bottom, the transmission wheel 272 is wrapped with a transmission belt 273.

[0037] In the implementation process, when the waste gas of the adhesive tape production workshop enters from the air inlet 1, at this time, the control console 24 will control the water pump 232 to start, then the water at the bottom of the inner cavity of the shell 1 21 is extracted through the water suction pipe 231, then the three delivery pipes 234 fixedly connected with the upper end of the converging cavity 233 are discharged into the inner cavity of the fixed plate 2351, then, because the fixed plate 2351 is communicated with the inner cavity of the communication rack 2352, the extracted water will be sprayed from the water sprayer provided at the bottom of the communication rack 2352, so that the adhesive tape production workshop contains larger particles falling to the surface of the filter plate 1 22, further, while the water pump 232 extracts the water at the bottom of the inner cavity of the shell 1 21, the motor 271 will start, in the process of starting the motor 271, the transmission wheel 272 fixedly connected with the output end will drive the transmission belt 273 to rotate, then the transmission belt 273 will drive the transmission wheel 272 fixedly connected with the bottom of the other three cyclone plates 2356 to rotate, so that under the action of the cyclone plate 2356, the waste gas generated in the adhesive tape production workshop will rise in the form of a spiral, then the water in the inner cavity of the fixed plate 2351 will enter the inner cavity of the spray head 2354 through the communication pipe 1 2353, then the gas rising in the form of a spiral is sprayed, then the waste gas will be gathered through the upper shell 2 25, then enter the processing assembly 2 3 from the inner cavity of the connecting pipe 1 26 to be processed in the next step;

[0038] The multi-stage waste gas treatment effectively combines the principles of water spraying, cyclone and gas rising, which can efficiently remove particulate matter and impurities in the waste gas. The water pump 232 and the water spraying device help to settle larger particles, while the cyclone plate 2356 enables the waste gas to fully contact with water and air in the spiral flow, enhancing the settlement of particulate matter and the removal of pollutants. Through multiple treatment processes, the waste gas treatment efficiency can be improved, energy consumption can be reduced, and the service life of the equipment can be effectively prolonged, ensuring a clean workshop environment and work efficiency.

[0039] It should be further noted that the left and right cyclone plates 2356 are oppositely arranged with the splitter vanes of the middle cyclone plate 2356.

[0040] In addition, the console 24 mentioned above is a very mature technical means in the prior art, and in the present scheme, only its controllable function is utilized, and its working principle and circuit connection are not described in detail.

[0041] Further, the water pump 232 mentioned above is a relatively mature technical means in the prior art, and in the present scheme, only its function of pumping water is utilized, and its working principle and circuit connection are not described in detail.

[0042] Further, the motor 271 mentioned above is a relatively mature technical means in the prior art, and in the present scheme, only its transmission function is utilized, and its working principle and circuit connection are not described in detail.

[0043] In the second embodiment, the waste gas is dry treated based on the first embodiment, and the specific implementation can be referred to Figure 6 and Figure 7 As shown in the drawings, the processing assembly two 3 includes a shell three 31, the left side of the inner cavity of the shell three 31 is fixedly connected with a dry filter plate 32, the middle of the inner cavity of the shell three 31 is fixedly connected with a W-shaped filter plate 33, the right side of the inner cavity of the shell three 31 is fixedly connected with a molecular sieve 34, and the right end of the shell three 31 is fixedly connected with a connecting pipe two 35. The air extraction assembly 6 includes a fan 61, the right side of the fan 61 is fixedly connected with a connecting pipe three 62, and the outer surface of the connecting pipe three 62 is fixedly connected with three connecting pipes four 63 which are in communication with the inner cavity of the purification barrel 42.

[0044] Specifically, in the present embodiment, after the exhaust gas enters the inner cavity of the shell three 31 through the connecting pipe one 26, it will be first filtered by the dry filter plate 32 fixedly connected on the left side of the inner cavity of the shell three 31 to capture larger particles and prevent these particles from entering the subsequent treatment system. Then, the W-shaped filter plate 33 increases the filtering surface area and improves the filtering effect on moisture and small particles, further removing fine impurities and moisture in the exhaust gas to ensure the purity of the exhaust gas. Finally, the exhaust gas after preliminary filtration will enter the molecular sieve 34, which adsorbs and captures harmful gases and moisture in the exhaust gas through its special pore structure, thereby achieving a more efficient purification effect.

[0045] Further, the multi-stage filtration system effectively improves the exhaust gas treatment efficiency. The dry filter plate 32 first captures larger particles to protect the subsequent equipment from damage by large particles. The W-shaped filter plate 33 increases the surface area to improve the filtering effect on moisture and small particles, further purifying the exhaust gas. The adsorption of the molecular sieve 34 efficiently removes harmful gases and residual moisture in the exhaust gas, ensuring that the final discharged exhaust gas is more pure. Such multiple filtration and adsorption design not only improves the exhaust gas purification effect, but also prolongs the service life of the equipment, reduces maintenance costs, and ensures stable operation of the system.

[0046] In addition, the working principle of the molecular sieve 34 is to selectively adsorb and separate different molecules through its microporous structure with regular pore size. When gas or liquid passes through the molecular sieve 34, only molecules with appropriate size can enter its pores and be adsorbed, thereby removing water, gas or impurities in the exhaust gas.

[0047] In Example Three, the purpose of desorption of the adsorption material is achieved on the basis of the above two examples. For further details, please refer to Figure 8 and Figure 9 and Figure 10As shown, the purification assembly 4 includes a connecting cavity 41, the upper end of the connecting cavity 41 is fixedly connected with three purification barrels 42, the inner cavities of the three purification barrels 42 are all fixedly connected with activated carbon pipes 44, the inner cavities of the three purification barrels 42 are all provided with gas sensors for detecting whether the activated carbon pipes 44 have been saturated by adsorption, the rear upper parts of the three purification barrels 42 are all fixedly connected with communication pipes two 43, the upper end of the outer shell four 45 is fixedly connected with the three purification barrels 42, the upper end of the outer shell four 45 is fixedly connected with an air outlet pipe 46, the desorption assembly 5 includes a catalytic assembly 51, the rear part of the catalytic assembly 51 is fixedly connected with a catalytic reaction area 52, the upper end of the catalytic reaction area 52 is fixedly connected with a reflux cavity one 53, the upper end of the reflux cavity one 53 is fixedly connected with a reflux cavity two 54, three matching holes 55 are formed in the front part of the reflux cavity two 54, the three matching holes 55 are all matched with the three communication pipes two 43, the catalytic assembly 51 includes an outer shell six 511, the inner cavity of the upper part of the outer shell six 511 is fixedly connected with a heat reaction area 512, the rear end of the heat reaction area 512 is fixedly connected with a partition plate 513, the bottom front side of the partition plate 513 is fixedly connected with a fixed frame 514, the inner cavity of the fixed frame 514 is fixedly connected with four groups of electric heating pipes 515, the rear end upper part of the outer shell six 511 is provided with a reflux hole 516.

[0048] Further, in the implementation process of the embodiment, when the exhaust gas enters the inner cavity of the connecting cavity 41 from the inner cavity of the connecting pipe two 35, then it will enter two of the purification barrels 42 and then rise, after the gas enters the inner cavity of the purification barrel 42, the harmful gas in the gas will be adsorbed by the activated carbon pipe 44, so as to be discharged into the atmosphere through the air outlet pipe 46 fixedly connected with the upper end of the outer shell four 45;

[0049] In addition, when the activated carbon pipe 44 fixedly connected in the inner cavity of the middle purification barrel 42 is saturated by adsorption, the electromagnetic valves installed on the upper and lower sides of the activated carbon pipe 44 will be closed under the control of the console 24, thereby forming a sealed state, at this time, the corresponding electromagnetic valves installed at the three connecting pipes four 63 will be opened, then the inner cavity of the saturated purification barrel 42 is extracted, so that the gas enters the inner cavity of the desorption assembly 5 through the fan 61, so that after the gas enters the inner cavity of the outer shell six 511, it first exchanges heat in the heat reaction area 512, then the heat-exchanged gas will move upwards from the bottom end of the outer shell six 511 along the inner side of the rear side of the outer shell six 511, then the gas passes through the heating area of the electric heating pipe 515 and is discharged through the reflux hole 516, in addition, during the gas discharging process, the catalyst in the catalytic reaction area 52 will enter the inner cavity of the reflux cavity two 54 together with the heated gas through the reflux cavity one 53, then enter the inner cavity of the purification barrel 42 through the corresponding communication pipe two 43, and perform backwashing and desorption on the activated carbon pipe 44, until the activated carbon pipe 44 in the next purification barrel 42 is saturated;

[0050] Through the intelligent control system and multi-stage desorption process, the service life of the activated carbon tube 44 is effectively prolonged and the purification efficiency is improved. When the activated carbon tube 44 is saturated, the control panel 24 controls the electromagnetic valve to be closed and starts other electromagnetic valves. The gas enters the desorption assembly 5 through the fan 61 for heat exchange. After heating and catalytic reaction, the gas enters the reflux cavity one 53 and the reflux cavity two 54, and backwashes the activated carbon tube 44 through the communication pipe two 43 for desorption regeneration. This design not only reduces the replacement frequency of the activated carbon, but also ensures the continuous cleaning of the gas during the purification process, effectively improving the overall operation efficiency.

[0051] The gas sensor mentioned in the above is a very mature prior art in the prior art. In the present scheme, only the function of detecting whether the activated carbon tube 44 is saturated is used, and the working principle and circuit connection are not described in detail.

[0052] Based on the above three embodiments, the working principle of the present scheme is as follows:

[0053] Firstly, when the exhaust gas enters the device from the air inlet 1, the larger particles in the exhaust gas are captured by the water spraying system when passing through the treatment assembly one 2. The control panel 24 starts the water pump 232 to extract the water at the bottom and sprays it into the air through the water extraction pipe 231, so as to promote the particles in the exhaust gas to settle on the filter plate one 22. At the same time, the exhaust gas forms a spiral upward flow under the action of the cyclone plate 2356, further forming full contact with water, enhancing the sedimentation effect of the particles. At this time, the impurities in the exhaust gas are treated by water, and the exhaust gas enters the treatment assembly two 3 for dry treatment.

[0054] The treatment assembly two 3 further purifies the exhaust gas through the dry filter system. The exhaust gas first passes through the dry filter plate 32 to remove larger particles, then passes through the W-shaped filter plate 33 to increase the filter surface area and improve the removal ability of small particles and moisture, and finally passes through the molecular sieve 34 for adsorption to remove harmful gases and moisture. The treated exhaust gas enters the purification assembly 4 through the connection pipe two 35.

[0055] The purification assembly 4 adsorbs the harmful gases in the exhaust gas through the activated carbon tube 44. When the activated carbon tube 44 is saturated, the gas sensor will monitor this state and control the electromagnetic valve to be closed through the control panel 24 to form a sealed state. At this time, the air extraction assembly 6 is started, and the fan 61 extracts the exhaust gas to the desorption assembly 5 through the air pipe for desorption regeneration treatment.

[0056] In the desorption process, the waste gas passes through the heating of the catalytic assembly 51, so that the adsorbed harmful substances are released, and then, after being heated by the heat reaction zone 512 and the electric heating pipe 515, the waste gas enters the reflux cavity one 53 and the reflux cavity two 54, driving the harmful substances to be desorbed from the activated carbon pipe 44. Through this backwashing and desorption process, the adsorption capacity of the activated carbon pipe 44 is restored, the service life is prolonged, and the purification efficiency is improved. The regenerated activated carbon will continue to be used for waste gas treatment, ensuring that the waste gas emission meets the environmental protection standards.

[0057] The basic principles and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
