Description

Technical Field

[0001] The present application relates to the technical field of waste gas treatment, and in particular to a waste gas treatment device. Background Art

[0002] Waste gas treatment, also known as waste gas purification, is a key environmental protection process designed to ensure that waste gas generated by industrial sites and factory workshops meets national emission standards before being discharged into the external environment.

[0003] The Chinese authorized patent (publication number CN112169463B) discloses an environmentally friendly waste gas treatment device, including a circulation mechanism, a cleaning mechanism is arranged inside the circulation mechanism, an air intake pipe is arranged on one side of the circulation mechanism, and a card slot is arranged at the bottom of the air intake pipe. It filters the passing waste gas in layers by arranging multiple filter balls in the annular body. When the filter ball needs to be cleaned, the filter ball is driven by the toggle block to rotate in the cleaning liquid in the lower half of the cavity, and rotates under the influence of the water flow to achieve the purpose of self-cleaning of the filter ball.

[0004] However, this cleaning method that relies solely on water flushing is not ideal when dealing with dust particles that stubbornly adhere to the inner and outer surfaces of the filter ball. It is difficult for water to completely remove these particles, and some dust particles are difficult to be dissolved by water, which easily causes the flushed dust particles to aggregate inside the filter ball. If they are not discharged in time, they will gradually clog the filter holes, thereby affecting the filtration efficiency and performance. This forces the staff to regularly shut down the machine to disassemble and manually clean the inside of the filter ball, which not only increases the burden on the workers, but may also cause economic losses due to production interruptions caused by downtime. Summary of the invention

DETAILED DESCRIPTION

[0030] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0031] The exhaust gas treatment equipment according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0032] like Figure 1-Figure 8 As shown, the exhaust gas treatment device of the embodiment of the present application includes a support frame 10, a main body 20, a filtering device 30, a first driving device 40, a second driving device 50 and a limiting mechanism 60.

[0033] The main body 20 includes two annular support walls 21 , an annular outer wall 22 and an annular inner wall 23 , wherein the two annular support walls 21 are symmetrically arranged on the support frame 10 , and the annular outer wall 22 is rotatably connected to the outer side walls of the two annular support walls 21 .

[0034] The annular inner wall 23 is rotatably connected to the inner walls of the two annular support walls 21, wherein the two annular support walls 21, the annular outer wall 22 and the annular inner wall 23 form an annular structure with an annular chamber 201, that is, an annular pipe, and the upper half of one of the annular support walls 21 is provided with an air inlet 202 and an air outlet 203 in sequence, and the lower half is provided with a water tank 204 connected to the annular chamber 201, and water inlets 205 are provided at both ends of the water tank 204, and a sewage outlet 206 is provided in the middle of the water tank 204.

[0035] It should be noted that the annular outer wall 22 and the annular inner wall 23 described in this embodiment are rotatably and sealingly connected to the two annular support walls 21 .

[0036] The filtering device 30 includes two partitions 31 and two groups of filtering components 32, wherein the two partitions 31 are symmetrically arranged in the annular chamber 201, and the partitions 31 are fixedly connected to the annular outer wall 22 and the annular inner wall 23 respectively, and the partitions 31 are movably connected to the two annular support walls 21, wherein the two partitions 31 divide the annular chamber 201 into two semi-annular chambers 2011.

[0037] It should be noted that the initial state of the two partitions 31 described in this embodiment is parallel to the ground, and the two partitions 31 are respectively located below the air inlet 202 and the air outlet 203, and completely separate the two semi-annular chambers 2011. In addition, by providing the two partitions 31, dust particles attached to the two annular support walls 21 can be scraped off, thereby playing a role in cleaning the inner walls of the two annular support walls 21.

[0038] Two groups of filter components 32 are respectively arranged in corresponding semi-annular chambers 2011, and each group of filter components 32 includes 3, 4, 5, 6, 7, 8, 9 filter components 32, etc. The specific number of use can be selected according to actual conditions and is not limited here. The filter components 32 are respectively fixedly connected to the annular outer wall 22 and the annular inner wall 23, and the filter components 32 are movably connected to the two annular support walls 21. The two groups of filter components 32 are used for intermittent and alternating filtering of dust particles in the exhaust gas.

[0039] It should be noted that the two groups of filter components 32 described in this embodiment intermittently and alternately filter the dust particles in the exhaust gas, which means that after one group of filter components 32 has filtered the dust particles in the exhaust gas for a long time, the other group of filter components 32 can be replaced to continue filtering the dust particles in the exhaust gas, and the replaced filter components 32 can be cleaned at the same time. Specifically, when a group of filter components 32 located in the semi-annular chamber 2011 in the upper half of the annular chamber 201 has filtered the dust particles in the exhaust gas for a long time, when the group of filter components 32 needs to be cleaned, the group of filter components 32 located in the upper half can be rotated to the semi-annular chamber 2011 in the lower half of the annular chamber 201, and the other group of filter components 32 located in the semi-annular chamber 2011 in the lower half is rotated to the semi-annular chamber 2011 in the upper half to filter the dust particles in the exhaust gas.

[0040] The first drive device 40 and the second drive device 50 are respectively arranged on the support frame 10, and the first drive device 40 is connected to the annular inner wall 23, wherein the first drive device 40 is used to drive the annular inner wall 23 to drive the filter device 30 and the annular outer wall 22 to rotate synchronously. The second drive device 50 is connected to two groups of filter components 32, wherein the second drive device 50 is used to drive the two groups of filter components 32 to move, and the limiting mechanism 60 is arranged on two annular support walls 21, and the limiting mechanism 60 is respectively connected to the two groups of filter components 32 in an intermittent conflicting manner. It should be noted that the first drive device 40 described in this embodiment drives the annular inner wall 23 to rotate 180 degrees each time it is started.

[0041] Specifically, when it is necessary to filter the dust particles in the exhaust gas, the relevant staff first needs to connect the air inlet 202 with the exhaust gas discharge port. At this time, the discharged exhaust gas enters the annular chamber 201. Since the two partitions 31 separate the annular chamber 201 into two semi-annular chambers 2011, the exhaust gas entering the annular chamber 201 flows in the semi-annular chamber 2011 located in the upper half of the annular chamber 201, and is filtered by a group of filter components 32 in the semi-annular chamber 2011 located in the upper half in turn, and is discharged from the air outlet 203.

[0042] When a group of filter components 32 located in the upper part filters the exhaust gas for a long time and needs to be cleaned, the staff can control the first drive device 40 to drive the annular inner wall 23 to drive the filter device 30 and the annular outer wall 22 to rotate 180 degrees synchronously. At this time, another group of filter components 32 located in the semi-annular chamber 2011 in the lower part of the annular chamber 201 is rotated to the semi-annular chamber 2011 in the upper part, thereby continuing to filter the exhaust gas.

[0043] Similarly, a group of filter components 32 located in the upper part is rotated into the semi-annular chamber 2011 in the lower part, and the limiting mechanism 60 now limits the group of filter components 32 located in the lower part. Then, the staff can connect the water outlet of the water pump to the two water inlets 205 respectively, and control the water pump to inject the cleaning liquid into the water tank 204. Since the water tank 204 is connected to the semi-annular chamber 2011 in the lower part of the annular chamber 201, the cleaning liquid entering the water tank 204 directly washes the filter components 32 in the lower part.

[0044] At the same time, the staff controls the second driving device 50 to drive the two groups of filter components 32 to move and remove the dust particles attached to the filter components 32. At this time, the cleaning liquid flushes the removed dust particles from the filter components 32 and discharges them through the sewage outlet 206, thereby completing the cleaning of the group of filter components 32, waiting to replace another group of filter components 32 to filter the exhaust gas, and the cycle continues. This can effectively improve the cleaning efficiency and effect, especially for stubbornly attached dust particles, which can be removed more thoroughly and reduce residues. At the same time, there is no need for staff to stop the machine regularly for disassembly and cleaning, thereby greatly reducing the frequency and burden of manual maintenance work.

[0045] In one embodiment of the present application, Figure 3-Figure 8 As shown, the filter assembly 32 includes a cylinder 321 , a support shaft 322 , filter balls 323 , a first arc-shaped scraper 324 , a second arc-shaped scraper 325 , a sealing mechanism 326 and a transmission mechanism 327 .

[0046] The cylinder 321 is fixedly disposed on the annular outer wall 22, and the cylinder 321 is in communication with the annular chamber 201. The support shaft 322 is fixedly disposed on the annular inner wall 23, and the support shaft 322 and the cylinder 321 are disposed coaxially.

[0047] The bottom of the filter ball 323 is rotatably sleeved on the support shaft 322, and the top of the filter ball 323 is rotatably connected to the cylinder 321, and the filter ball 323 is in communication with the cylinder 321. It should be noted that the outer periphery of the filter ball 323 described in this embodiment fits the annular chamber 201, that is, when the exhaust gas passes through the annular chamber 201, it must be filtered by the filter ball 323 before being discharged.

[0048] The first arc scraper 324 is fixedly disposed on the support shaft 322 , and the first arc scraper 324 is in contact with the inner wall of the filter ball 323 , wherein the first arc scraper 324 is used to scrape off dust particles attached to the inner surface of the filter ball 323 .

[0049] The second arc scraper 325 is fixedly disposed between the annular outer wall 22 and the annular inner wall 23 , and the second arc scraper 325 fits the outer wall of the filter ball 323 , wherein the second arc scraper 325 is used to scrape off dust particles attached to the outer surface of the filter ball 323 .

[0050] In the embodiment of the present application, in order to facilitate the first curved scraper 324 and the second curved scraper 325 to scrape away the dust particles attached to the inner and outer surfaces of the filter ball 323, and to brush the inner and outer surfaces of the filter ball 323 to improve the cleaning efficiency and effect, a brush (not shown in the figure) can be further arranged inside the side wall where the first curved scraper 324 and the second curved scraper 325 are in contact with the filter ball 323.

[0051] The sealing mechanism 326 includes a sealing cover 3261 , a plurality of tensioning components 3262 , a sleeve 3263 and a driving block 3264 .

[0052] The sealing cover 3261 is arranged on the cylinder 321 in a lifting and moving manner, wherein the sealing cover 3261 is used to seal the top of the cylinder 321, and a plurality of grooves 301 distributed in a circumferential array are provided on the top wall of the cylinder 321. A plurality of tensioning components 3262 are respectively arranged in the corresponding grooves 301, for example, the plurality of tensioning components 3262 can be 3, 4, 5, 6 tensioning components 3262, etc., and the specific number of arrangements can be selected according to actual conditions and is not limited here, and one end of the tensioning component 3262 is fixedly connected to the bottom wall of the groove 301, and the other end of the tensioning component 3262 is fixedly connected to the sealing cover 3261.

[0053] The sleeve 3263 is vertically fixed on the sealing cover 3261 , and the driving block 3264 is fixed on the sleeve 3263 .

[0054] The transmission mechanism 327 includes a connecting shaft 3271 and a driven gear 3272, wherein one end of the connecting shaft 3271 is fixedly connected to the top of the filter ball 323 through a connecting frame, and the other end of the connecting shaft 3271 passes through the sealing cover 3261, the sleeve 3263 and the driving block 3264 in sequence and is connected to the driven gear 3272.

[0055] In order to clearly explain the above embodiment, Figure 7 and Figure 8 As shown, in one embodiment of the present application, the tensioning component 3262 includes a support column 32621 and a tension spring 32622 , wherein the support column 32621 is movably arranged in the groove 301 , and the top end of the support column 32621 is fixedly connected to the sealing cover 3261 .

[0056] The tension spring 32622 is disposed in the groove 301 , and one end of the tension spring 32622 is fixedly connected to the bottom end of the support column 32621 , and the other end of the tension spring 32622 is fixedly connected to the bottom wall of the groove 301 .

[0057] Further, in one embodiment of the present application, Figure 1 and Figure 4 As shown, the first driving device 40 includes an inner ring gear 41 , a first driving mechanism 42 and a driving gear 43 .

[0058] The inner gear ring 41 is fixedly disposed on the annular inner wall 23 , the first driving mechanism 42 is disposed on the support frame 10 , and the output end of the first driving mechanism 42 is connected to the driving gear 43 , wherein the driving gear 43 is meshed with the inner gear ring 41 .

[0059] It should be noted that the first drive mechanism 42 described in this embodiment is a motor with a self-locking function, i.e., a self-locking motor, which can self-lock the motor shaft (output shaft) to prevent it from rotating when the power is turned off. Moreover, each time the first drive mechanism 42 is powered, the driving gear 43 drives the inner gear ring 41 to rotate 180 degrees.

[0060] Further, in one embodiment of the present application, Figure 1-Figure 3 As shown, the second driving device 50 includes an outer ring gear 51 , a worm wheel 52 , a worm 53 and a second driving mechanism 54 .

[0061] The outer gear ring 51 is rotatably mounted on the support frame 10, and meshes with the driven gear 3272. The worm wheel 52 is sleeved on the outer gear ring 51. The worm 53 is rotatably mounted on the support frame 10, and meshes with the worm wheel 52. It should be noted that the outer gear ring 51 described in this embodiment is a ring gear with meshing teeth on the side.

[0062] The second driving mechanism 54 is disposed on the support frame 10 , and an output end of the second driving mechanism 54 is connected to one end of the rotating shaft of the worm 53 .

[0063] It should be noted that the second driving mechanism 54 described in this embodiment may be a servo motor.

[0064] Further, in one embodiment of the present application, Figure 1-Figure 5 As shown, the limiting mechanism 60 includes two arc-shaped limiting rods 61 and two groups of supporting rods 62 .

[0065] The two arc-shaped limiting rods 61 are symmetrically arranged on both sides of the sleeve 3263, and the two arc-shaped limiting rods 61 are intermittently connected with the driving block 3264. It should be noted that the arc-shaped limiting rod 61 described in this embodiment is semicircular, and both ends are bent inward and located between the sealing cover 3261 and the driving block 3264.

[0066] One end of the two groups of support rods 62 are fixedly connected to the corresponding arc-shaped limit rods 61, and the other ends are fixedly connected to the corresponding annular support walls 21. Each group of support rods 62 includes 4, 5, 6, 7, 8, 9 support rods 62, etc. The specific number of support rods used can be selected according to actual conditions and is not limited here.

[0067] Specifically, when the exhaust gas discharge port is connected to the air inlet 202, the exhaust gas is filtered by the multiple filter balls 323 located in the upper half (i.e., the upper half of the annular chamber 201) and the filtered exhaust gas is discharged through the air outlet 203. The dust particles in the exhaust gas are filtered on the multiple filter balls 323 located in the upper half of the semi-annular chamber 2011 in turn.

[0068] After the multiple filter balls 323 filter the exhaust gas for a period of time, in order to effectively maintain the filtering efficiency and performance of the filter balls 323, it is necessary to remove the dust particles attached to the inner and outer surfaces of the filter balls 323. To this end, the staff can control the first driving mechanism 42 to drive the driving gear 43 to drive the inner gear ring 41 to rotate, and the rotating inner gear ring 41 drives the filter device 30 and the annular outer wall 22 to rotate 180 degrees synchronously through the annular inner wall 23.

[0069] During the rotation of the filter device 30, the partition plate 31 in the filter device 30 scrapes off the dust particles attached to the two annular support walls 21 to clean the inner wall of the annular support wall 21. At the same time, since the driven gear 3272 in the filter assembly 32 is meshed with the outer gear ring 51, when the filter device 30 rotates, the driven gear 3272 is driven to rotate, and the rotating driven gear 3272 drives the filter ball 323 to rotate through the connecting shaft 3271. Since the first arc scraper 324 and the second arc scraper 325 are both fixed, during the rotation of the filter ball 323, the first arc scraper 324 and the second arc scraper 325 scrape off the dust particles attached to the inner and outer surfaces of the filter ball 323.

[0070] When a group of filter components 32 in the upper semi-annular chamber 2011 rotates to the lower semi-annular chamber 2011 (i.e., the lower half of the annular chamber 201), another group of filter components 32 in the lower semi-annular chamber 2011 is rotated to the upper semi-annular chamber 2011, and the dust particles in the exhaust gas are further filtered through the filter balls 323 in the other group of filter components 32. No shutdown operation is required, which not only helps enterprises maintain continuous and stable production, but also effectively reduces the economic losses caused by shutdown maintenance.

[0071] When a group of filter components 32 located in the upper semi-annular chamber 2011 rotates toward the lower semi-annular chamber 2011, the driving block 3264 in the filter component 32 gradually contacts the outer periphery of the arc-shaped limit rod 61 from one end of the arc-shaped limit rod 61. At this time, the driving block 3264 is pressed by the arc-shaped limit rod 61 to move away from the cylinder 321. The moving driving block 3264 drives the sealing cover 3261 to move away from the cylinder 321 through the sleeve 3263. At the same time, the moving sealing cover 3261 stretches the tension spring 32622 through the support column 32621. At this time, the opening at the top of the cylinder 321 sealed by the sealing cover 3261 is opened, and the opening of the cylinder 321 is rotated to face downward.

[0072] Then, the staff connects the water outlet of the water pump to the two water inlets 205 respectively, and controls the water pump to inject cleaning liquid into the water tank 204 to flush the filter balls 323 in a group of filter components 32 located in the lower annular chamber 2011.

[0073] At the same time, the staff can control the second driving mechanism 54 to drive the worm 53 to rotate, the rotating worm 53 drives the worm wheel 52 to drive the outer gear ring 51 to rotate, the rotating outer gear ring 51 drives the driven gear 3272 to rotate, the rotating driven gear 3272 drives the filter ball 323 to rotate, and the fixed first arc scraper 324 and the second arc scraper 325 scrape and clean the inner and outer surfaces of the filter ball 323. Therefore, it is no longer necessary to rely solely on water flushing to clean the inner and outer surfaces of the filter ball, which can significantly improve the cleaning efficiency and effect, especially for stubbornly attached dust particles, which can be removed more effectively and thoroughly, reducing residue.

[0074] The dust particles cleaned from the outer surface of the filter ball 323 are discharged from the sewage outlet 206 under the flushing effect of the cleaning liquid. The dust particles cleaned from the inner surface of the filter ball 323 are discharged from the opening of the cylinder 321 under the flushing effect of the cleaning liquid (refer to Figure 1As shown in the figure). This enables the cleaned dust to be discharged from the inside of the filter ball more effectively, reducing the accumulation of dust in the filter ball and the clogging of the filter holes, thereby effectively maintaining the filtering efficiency and performance of the filter ball.

[0075] As a possible situation, in order to improve the filtering effect of the exhaust gas, the multiple filter balls 323 in each group of filter components 32 can also be sequentially arranged as filter balls 323 with different filter hole diameters. That is, the filter hole diameters of the multiple filter balls 323 sequentially distributed from the air inlet 202 to the air outlet 203 are gradually decreased (reduced) (that is, the filter hole diameter of the filter ball 323 near the air inlet 202 is much larger than the filter hole diameter of the filter ball 323 near the air outlet 203.).

[0076] It is understandable that such a setting can perform layered filtration on dust particles of different sizes in the exhaust gas, which can not only improve the filtering effect on the exhaust gas, but also help to extend the filtration cycle and filtration performance of the filter ball 323, reduce the number of times the filter ball 323 is cleaned, and reduce the maintenance cost of the filter ball 323.

[0077] In summary, the waste gas treatment equipment of the embodiment of the present application can quickly remove dust attached to the inner and outer surfaces of the filter ball, effectively maintaining the filtration efficiency and performance of the filter ball. At the same time, there is no need for staff to regularly shut down the machine to disassemble and clean the inside of the filter ball, thereby greatly reducing the frequency and burden of manual maintenance work. This not only helps enterprises maintain continuous and stable production, but also effectively reduces the economic losses caused by shutdown maintenance.
