DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] For example, see Figure 1 and Figure 2 As shown, a waste gas treatment device for a tape production workshop includes an air inlet 1, a treatment component 1 2 is fixedly connected to the right side of the air inlet 1, a treatment component 2 3 is fixedly connected to the right side of the treatment component 1 2, a purification component 4 is fixedly connected to the rear of the treatment component 2 3, a desorption component 5 is fixedly connected to the left side of the purification component 4, and an exhaust component 6 is fixedly connected to the front end of the desorption component 5.

[0033] During the specific implementation of this plan, the operator is first required to connect the air inlet 1 to the exhaust gas extraction device of the tape production workshop, and then adjust the parameters of the internal components of the processing component 2 according to the implementation situation. Further, the components inside the processing component 2 will process the exhaust gas entering from the air inlet 1, so that the exhaust gas rises in a spiral form, and then the exhaust gas 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 processing component 2, and the gas rising in a spiral manner will eventually be discharged from the pipe fixedly connected to the upper part of the processing component 2 into the inner cavity of the processing component 23, and then the processing component 23 will dry-treat the exhaust gas inside the processing component 2, and after the wet-treated exhaust gas is dry-separated by the processing component 23, it will pass through the right side of the processing component 23. The pipe on the side enters the inner cavity of the purification component 4, and then the adsorbent material installed in the inner cavity of the purification component 4 will adsorb the harmful gas in the exhaust gas, and the adsorbed gas will be discharged into the atmosphere. Further, when the adsorbent material in the inner cavity of the purification component 4 reaches a saturated state, the solenoid valves installed at the bottom and the top of the purification component 4 will be closed, so that the purification component 4 is in a sealed state. At this time, the exhaust component 6 will extract the air from the bottom of the inner cavity of the purification component 4, and transport the extracted air to the inner cavity of the desorption component 5, and then desulfurize the air in the inner cavity of the purification component 4. After the desorption component 5 is heated, the internal components of the desorption component 5 will release the catalyst, and then enter the inner cavity of the purification component 4 together with the heated gas. Subsequently, the adsorbent material is backwashed to restore its adsorption capacity.

[0034] Furthermore, through the cooperation between processing component 1 2 and processing component 2 3, combined with the synergistic effect of adsorption and desorption component 5, efficient removal of particulate matter and harmful gases in the exhaust gas is achieved. Processing component 1 2 can effectively remove particulate matter in the exhaust gas, while processing component 2 3 further removes 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 component 5 can restore its adsorption capacity to extend its service life and reduce labor costs and filter element materials.

[0035] Furthermore, the solenoid valve mentioned above is a very mature existing technical means in the prior art. In this solution, only its function of being controlled by the control end and then opened and closed is utilized, and its working principle is not elaborated in detail;

[0036] See also Figure 3 and Figure 4 as well as Figure 5As shown, the processing component 2 includes a shell 21, a filter plate 22 is fixedly connected to the middle of the inner cavity of the shell 21, a pumping component 23 is fixedly connected to the front side of the shell 21, a control console 24 is fixedly connected to the right side of the shell 21, a shell 25 is fixedly connected to the upper end of the shell 21, a connecting pipe 26 is fixedly connected to the upper end of the shell 25, a transmission component 27 is fixedly connected to the front side of the shell 21, and the pumping component 23 includes a water pumping pipe 231, the water pumping pipe 231 is fixedly connected to the bottom of the front side of the shell 21, a water pump 232 is fixedly connected to the upper end of the water pump 232, a confluence chamber 233 is fixedly connected to the output end of the water pump 232, and three delivery pipes 234 are fixedly connected to the upper end of the confluence chamber 233. The three delivery pipes 23 The other end is fixedly connected with a spray assembly 235, the spray assembly 235 comprises a fixed plate 2351, a connecting frame 2352 is fixedly connected to the middle of the fixed plate 2351, a water sprayer is arranged at the bottom of the connecting frame 2352, a connecting pipe 2353 is fixedly connected to the bottom of the connecting frame 2352, a spray head 2354 is rotatably connected to the bottom of the connecting pipe 2353, a support frame 2355 is rotatably connected to the bottom of the outer surface of the spray head 2354, a swirl plate 2356 is fixedly connected to the side of the outer surface of the spray head 2354 away from the support frame 2355, and a transmission assembly 27 comprises a motor 271, a transmission wheel 272 is fixedly connected to the bottom of the motor 271 through a coupling, and a transmission belt 273 is wound around the outer surface of the transmission wheel 272.

[0037] In the present implementation process, when the exhaust gas from the tape production workshop enters from the air inlet 1, at this time, the control console 24 will control the water pump 232 to start, and then extract the water from the bottom of the inner cavity of the shell 21 through the water pumping pipe 231, and then discharge it to the inner cavity of the fixed plate 2351 through the three delivery pipes 234 fixedly connected from the upper end of the confluence cavity 233. Then, because the fixed plate 2351 is connected with the inner cavity of the connecting frame 2352, the extracted water will be sprayed out from the sprinkler set at the bottom of the connecting frame 2352, so that the larger particles in the tape production workshop fall to the surface of the filter plate 22. Further, while the water pump 232 is extracting the water from the bottom of the inner cavity of the shell 21, the motor 271 will be started. During the startup of 71, the transmission wheel 272 fixedly connected to the output end will drive the transmission belt 273 to rotate, and then the transmission belt 273 will drive the transmission wheels 272 fixedly connected to the bottom of the other three swirl plates 2356 to rotate, so that under the action of the swirl plates 2356, the waste gas generated in the tape production workshop will rise in a spiral form, and then the water in the inner cavity of the fixed plate 2351 will enter the inner cavity of the spray head 2354 through the connecting pipe 1 2353, and then the rising gas in the spiral form will be rotated and sprayed, and then the waste gas will be gathered through the upper shell 25, and then enter the processing component 23 through the inner cavity of the connecting pipe 1 26 to be processed in the next step;

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

[0039] It should be further explained that the diverter blades of the left and right swirl plates 2356 and the middle swirl plate 2356 are arranged oppositely;

[0040] In addition, the console 24 mentioned above is a very mature technical means in the prior art. In this solution, only its control function is used, and its working principle and line connection are not elaborated in detail.

[0041] Furthermore, the water pump 232 mentioned above is a relatively mature technical means in the prior art. In this solution, only its function of pumping water is used, and its working principle and line connection are not elaborated in detail;

[0042] Furthermore, the motor 271 mentioned above is a relatively mature technical means in the prior art. In this solution, only its transmission function is utilized, and its working principle and circuit connection are not elaborated in detail.

[0043] Embodiment 2: This embodiment achieves the effect of dry treatment of exhaust gas based on embodiment 1. For details, please refer to Figure 6 and Figure 7 As shown, the processing component 2 3 includes a shell 3 31, a dry filter plate 32 is fixedly connected to the left side of the inner cavity of the shell 31, a W-shaped filter plate 33 is fixedly connected to the middle part of the inner cavity of the shell 31, a molecular sieve 34 is fixedly connected to the right side of the inner cavity of the shell 31, and a connecting pipe 2 35 is fixedly connected to the right end of the shell 31. The exhaust component 6 includes a fan 61, a connecting pipe 3 62 is fixedly connected to the right side of the fan 61, and three connecting pipes 4 63 communicating with the inner cavity of the purification barrel 42 are fixedly connected to the upper part of the outer surface of the connecting pipe 3 62.

[0044] Specifically, in the present implementation process, after the exhaust gas enters the inner cavity of the shell three 31 through the connecting pipe one 26, it will first be filtered by the dry filter plate 32 fixedly connected to 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 to improve the filtering effect on moisture and tiny particles, further removes fine impurities and moisture in the exhaust gas, and ensures 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] Furthermore, the multi-stage filtration system effectively improves the waste gas treatment efficiency. The dry filter plate 32 first captures larger particles to protect subsequent equipment from damage by large particles; the W-shaped filter plate 33 further purifies the waste gas by increasing the surface area to improve the filtration effect on moisture and tiny particles; the adsorption effect of the molecular sieve 34 efficiently removes harmful gases and residual moisture in the waste gas to ensure that the final exhaust gas is purer. Such a multiple filtration and adsorption design not only improves the waste gas purification effect, but also prolongs the equipment life, 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 sizes. When gas or liquid passes through the molecular sieve 34, only molecules of suitable size can enter its pores and be adsorbed, thereby removing moisture, gas or impurities in the exhaust gas.

[0047] Example 3: This example achieves the purpose of desorbing the adsorbent material based on the above two examples. For further information, please refer to Figure 8 and Fig. 9 as well as Fig.10As shown, the purification component 4 includes a connecting chamber 41, and three purification barrels 42 are fixedly connected to the upper end of the connecting chamber 41. The inner cavities of the three purification barrels 42 are all fixedly connected to activated carbon tubes 44. The inner cavities of the three purification barrels 42 are all provided with gas sensors for detecting whether the activated carbon tubes 44 are saturated with adsorption. The upper parts of the rear sides of the three purification barrels 42 are all fixedly connected to connecting pipes 2 43. The upper ends of the three purification barrels 42 are commonly fixedly connected to outer shells 45, and the upper ends of the outer shells 45 are fixedly connected to air outlet pipes 46. The desorption component 5 includes a catalytic component 51, and the rear of the catalytic component 51 is fixedly connected to a catalytic reaction zone 52. The catalytic reaction The upper end of zone 52 is fixedly connected with reflux chamber 1 53, the upper end of reflux chamber 1 53 is fixedly connected with reflux chamber 2 54, the front part of reflux chamber 2 54 is provided with three matching holes 55, the three matching holes 55 are matched with three connecting pipes 2 43, the catalytic component 51 includes outer shell 6 511, the upper part of the inner cavity of outer shell 6 511 is fixedly connected with thermal reaction zone 512, the rear end of thermal reaction zone 512 is fixedly connected with partition 513, the front side of the bottom of partition 513 is fixedly connected with fixed frame 514, the inner cavity of fixed frame 514 is fixedly connected with four groups of electric heating tubes 515, and the upper part of the rear end of outer shell 6 511 is provided with reflux hole 516.

[0048] Furthermore, during the implementation of this embodiment, when the exhaust gas enters the inner cavity of the connecting cavity 41 from the inner cavity of the connecting pipe 2 35, it will then enter from 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 tube 44, and then discharged into the atmosphere through the outlet pipe 46 fixedly connected to the upper end of the outer shell 45;

[0049] In addition, when the activated carbon tube 44 fixedly connected to the inner cavity of the purification barrel 42 located in the middle is fully adsorbed, the solenoid valves installed on the upper and lower sides of the activated carbon tube 44 will be controlled by the console 24 to close, thereby forming a sealed state. At this time, the corresponding solenoid valves installed at the three connecting pipes 463 will be opened, and then the adsorption saturated inner cavity of the purification barrel 42 will be extracted, so that the gas enters the inner cavity of the desorption component 5 through the fan 61, and then the gas enters the inner cavity of the shell 6 511, first passes through the thermal reaction zone 512 for heat exchange, and then the gas after heat exchange will flow along the outer The inside of the rear side of the shell six 511 moves upward from the bottom end of the outer shell six 511, and then the gas passes through the heating area of ​​the electric heating tube 515 and is discharged through the reflux hole 516. In addition, when the gas is about to be discharged, the catalytic reaction zone 52 will allow the internal catalyst to pass through the reflux chamber one 53 and enter the inner cavity of the reflux chamber two 54 together with the heated gas, and then enter the inner cavity of the purification barrel 42 through the corresponding connecting pipe two 43, and backwash and desorb the activated carbon tube 44 until the activated carbon tube 44 in the inner cavity of the purification barrel 42 under the activated carbon tube 44 is saturated;

[0050] Through the intelligent control system and multi-stage desorption process, the service life of the activated carbon tube 44 is effectively extended and the purification efficiency is improved. When the activated carbon tube 44 is saturated with adsorption, the control console 24 controls the solenoid valve to close and starts other solenoid valves. The gas enters the desorption component 5 through the fan 61 for heat exchange. After heating and catalytic reaction, the gas enters the reflux chamber 1 53 and the reflux chamber 2 54, and backwashes the activated carbon tube 44 through the connecting pipe 2 43 for desorption and regeneration. This design not only reduces the frequency of activated carbon replacement, but also ensures the continuous cleaning of the gas during the purification process, effectively improving the overall operation efficiency;

[0051] Furthermore, the gas sensor mentioned above is a very mature existing technical means in the prior art. In this solution, only its function of detecting whether the activated carbon tube 44 is adsorbed saturated is utilized, and its working principle and circuit connection are not elaborated in detail;

[0052] Based on the above three embodiments, the working principle of this solution is:

[0053] First, when the exhaust gas enters the device from the air inlet 1 and passes through the treatment component 1 2, the larger particles in the exhaust gas will be captured by the water spraying system, and the control console 24 starts the water pump 232, extracts the bottom water through the water pumping pipe 231 and sprays it into the air, so that the particles in the exhaust gas are settled on the filter plate 1 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 the water, thereby enhancing the sedimentation effect of the particles. At this time, after the impurities in the exhaust gas are treated by water, the exhaust gas enters the treatment component 2 3 for dry treatment;

[0054] The treatment component 2 3 further purifies the waste gas through the dry filtration system. The waste gas first passes through the dry filter plate 32 to remove larger particles, and then passes through the W-shaped filter plate 33 to increase the filtration surface area and improve the removal capacity of small particles and moisture. Finally, the waste gas is adsorbed by the molecular sieve 34 to remove harmful gases and moisture. The treated waste gas then enters the purification component 4 through the connecting pipe 2 35;

[0055] The purification component 4 adsorbs harmful gases in the exhaust gas through the activated carbon tube 44. After the harmful components in the exhaust gas are adsorbed by the activated carbon tube 44, they are discharged into the atmosphere through the air outlet pipe 46. When the adsorption of the activated carbon tube 44 reaches saturation, the gas sensor will detect this state and control the solenoid valve to close through the control console 24 to form a sealed state. At this time, the exhaust component 6 is started, and the fan 61 extracts the exhaust gas to the desorption component 5 through the air duct for desorption regeneration treatment;

[0056] During the desorption process, the exhaust gas is heated by the catalytic component 51, so that the adsorbed harmful substances are released. Then, after being heated by the thermal reaction zone 512 and the electric heating tube 515, the exhaust gas enters the reflux chamber 1 53 and the reflux chamber 2 54, driving the harmful substances to be desorbed from the activated carbon tube 44. Through this backwashing and desorption process, the adsorption capacity of the activated carbon tube 44 is restored, its service life is extended, and the purification efficiency is improved. The regenerated activated carbon will continue to be used for exhaust gas treatment to ensure that the exhaust gas emissions meet environmental protection standards.
