Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to waste gas treatment and dust reduction equipment. Background Art

[0002] Waste gas purification mainly refers to the treatment of industrial waste gas generated in industrial sites, which may include dust particles, smoke and soot, odorous gases, toxic and harmful gases, etc. The purpose of waste gas purification is to make the waste gas meet the requirements of waste gas emission standards through a series of treatment measures before it is discharged into the atmosphere, thereby reducing the harm to the environment and human health.

[0003] There are many methods for exhaust gas purification, the most common of which include the following: absorption, adsorption, condensation and combustion. The absorption method refers to the use of physical or chemical interactions between liquid and pollutants in the exhaust gas to transfer pollutants from the gas phase to the liquid phase. This method is suitable for treating soluble substances in the exhaust gas.

[0004] A Chinese patent with authorization announcement number CN116422085B discloses an exhaust gas treatment device and method, which includes an exhaust gas treatment device body, an air injection pipe arranged on one side of the exhaust gas treatment device body, and an exhaust pipe arranged on the top of the exhaust gas treatment device body. A filter screen is provided on the inner wall of the exhaust gas treatment device body, and the filter screen divides the internal space of the exhaust gas treatment device body into two layers, an upper layer and an lower layer. The air injection pipe is located above the filter screen. A first baffle plate parallel to the filter screen is rotatably connected to the inner wall of the exhaust gas treatment device body above the filter screen. A first air inlet is provided on the first baffle plate. A water permeable plate is rotatably provided above the first baffle plate on the exhaust gas treatment device body. A plurality of water permeable holes are provided on the water permeable plate. A water inlet pipe is provided on the side wall of the exhaust gas treatment device body. The outlet of the water inlet pipe is located above the water permeable plate. A scraper is slidably connected to the inner wall of the exhaust gas treatment device body. The lower end of the scraper contacts the upper end surface of the filter screen, and a driving member for driving the scraper to reciprocate on the filter screen is provided on the exhaust gas treatment device body.

[0005] The above patent discharges the water in the water inlet pipe evenly to the bottom of the water permeable plate through the water permeable holes on the water permeable plate. At this time, the exhaust gas entering from the first air inlet of the first baffle is flushed, so that the dust in the exhaust gas is adsorbed by the water droplets, reducing the dust content in the exhaust gas and reducing pollution to the environment. The water falling from the water permeable plate flows onto the first baffle, and then flows from the first air inlet of the first baffle to the filter net. At this time, the filter net filters the water, so that impurities remain above the filter net, and water without impurities flows to the bottom of the filter net for easy reuse.

[0006] However, when the filter is filtering water, impurities may get stuck in the filter holes. When the scraper is scraping the filter, the impurities will be further pushed into the filter holes, further blocking the filter. Summary of the invention

[0007] The present invention provides an exhaust gas treatment and dust reduction device, aiming to solve the problem in the related art that when the filter screen filters water, impurities may be stuck in the filter screen holes, causing the filter screen to be blocked.

[0008] The waste gas treatment and dust reduction equipment of the present invention comprises: a housing;

[0009] A spray device is provided inside the shell, a filter plate is provided below the spray device, and a circulation device is provided outside the shell, and the circulation device is used to send the liquid below the filter plate into the spray device;

[0010] A cleaning component is provided on the filter plate, and the cleaning component includes a rotating shaft, a water collecting bucket and a collecting plate. The rotating shaft is rotatably fitted on the shell, and a first driving member is provided in the shell, and the first driving member is used to drive the rotating shaft to rotate. The water collecting bucket is provided on the rotating shaft, and the side wall of the water collecting bucket has a water inlet, and the top of the water collecting bucket has a water outlet. The width of the water inlet is greater than the width of the water outlet. The water collecting bucket is located below the filter plate, and the collecting plate is provided on the rotating shaft and above the filter plate.

[0011] Beneficial effect: The water collecting bucket is located below the liquid level of the cleaning liquid at the bottom of the shell. When the first driving member drives the rotating shaft to rotate, the rotating shaft drives the water collecting bucket to rotate, and the cleaning liquid enters the water collecting bucket from the water inlet. Under the squeezing of the water collecting bucket, a high-speed water flow is formed and sprayed out from the water outlet, backwashing the filter plate from bottom to top to prevent the filter plate from being blocked.

[0012] Preferably, a lifting plate is slidably fitted on the rotating shaft, and a second driving member is provided at the bottom of the shell body, and the second driving member is used to drive the lifting plate to move up and down.

[0013] The effect is that the height of the liquid level at the bottom of the shell is adjusted by moving the lifting plate up and down, thereby ensuring that the water collecting bucket is always below the liquid level.

[0015] The effect is that when the filter plate is completely blocked, the cleaning liquid in the water collecting bucket cannot be discharged through the water outlet, and the push plate is close to the mounting seat under the resistance of the cleaning liquid, thereby pushing the second magnet to rotate, so that the first magnet and the second magnet attract each other, and under the action of gravity, the movable groove and the second movable groove overcome the elastic force of the first elastic member and the second elastic member to move downward and close to the upper surface of the filter plate. At this time, the half gear is engaged with the filter plate, and the rotating shaft continues to rotate to make the half gear move along the filter plate, thereby driving the second magnet to rotate, so that the first magnet and the second magnet repel each other, and the movable plate moves upward under the action of the repulsive force and the elastic force of the second elastic member, and the impurities in the filter holes of the filter plate are sucked out by negative pressure, thereby achieving dredging through the filter plate.

[0016] Preferably, the collecting plate is an arc-shaped structure, and a side thereof away from the water collecting bucket is higher than a side thereof close to the water collecting bucket.

[0017] The effect is that the side of the collecting plate away from the water collecting bucket is higher than the side of the collecting plate close to the water collecting bucket, thereby preventing the cleaning liquid that is backwashed onto the collecting plate from passing over the cleaning plate and directly falling onto the filter plate.

[0018] Preferably, a slag discharge pipe is further provided in the rotating shaft, the slag discharge pipe is fixedly connected to the rotating shaft and communicated with the outside, a slag discharge port is provided on the side wall of the rotating shaft, the slag discharge port is communicated with the slag discharge pipe, and the bottom end of the slag discharge pipe is flush with the collecting plate.

[0020] The effect is that the auger blades can push impurities on the collection plate into the inspection port.

[0021] Preferably, the collecting plate is provided with a water filter hole, and the water filter hole is located at the outer end of the collecting plate.

[0022] Preferably, a water diversion groove is further provided on the collecting plate, and the water diversion groove is distributed obliquely, and an end thereof close to the rotating shaft is higher than an end thereof close to the water filtering hole.

[0023] By adopting the above technical solution, the beneficial effects of the present invention are:

[0024] According to the waste gas treatment and dust reduction equipment of the present invention, the water collecting bucket is located below the liquid level of the cleaning liquid at the bottom of the shell. When the first driving member drives the rotating shaft to rotate, the rotating shaft drives the water collecting bucket to rotate, and the cleaning liquid enters the water collecting bucket from the water inlet. Under the squeezing of the water collecting bucket, a high-speed water flow is formed and sprayed out from the water outlet, and the filter plate is backwashed and cleaned from bottom to top to prevent the filter plate from being blocked.

[0036] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0037] like Figures 1 to 9 As shown, the waste gas treatment and dust reduction equipment of the present invention includes: a shell 1.

[0038] Specifically, Figure 1 and Figure 2 As shown, an air inlet is provided on the side wall of the shell 1, and an air outlet is provided at the top thereof. A spray device 2 is also provided at the top inside the shell 1. The height of the spray device 2 is higher than the height of the air inlet. A filter plate 3 is provided below the spray device 2, and the filter plate 3 is fixedly connected to the shell 1. A circulation device 4 is provided next to the shell 1. The circulation device 4 is a water pump, one end of the water pump is connected to the bottom of the shell 1, and the other end is connected to the spray device 2. The circulation device 4 can pump the cleaning liquid at the bottom of the shell 1 into the spray device 2. The spray device 2 includes a water pipe and a nozzle, and the nozzles are distributed at intervals at the bottom of the water pipe. The water pumped into the water pipe through the circulation device 4 can spray the water pipe through the nozzle, and the cleaning liquid sprayed from the nozzle can absorb dust in the gas to be treated in the shell 1, so as to realize dust reduction treatment of the gas in the shell 1, and the treated gas is discharged from the air outlet, and the cleaning liquid with dust is filtered through the filter plate 3 and returns to the bottom of the shell 1.

[0039] like Figures 2 to 5As shown, the filter plate 3 is also provided with a cleaning assembly, which includes a rotating shaft 5, a water collecting bucket 6 and a collecting plate 7. The rotating shaft 5 is rotatably matched with the bottom end of the housing 1, the rotating shaft 5 is coaxially distributed with the housing 1, the top of the rotating shaft 5 extends upward, and a fixed seat 51 is slidably matched on the rotating shaft 5, and the fixed seat 51 is fixedly connected with the filter plate 3. A first driving member 8 is provided at the bottom end of the housing 1, and the first driving member 8 is a motor. The output end of the first driving member 8 is fixedly connected with a driving gear, and the driving gear is meshed with the side wall of the rotating shaft 5. The first driving member 8 is used to drive the rotating shaft 5 to rotate. The water collecting bucket 6 is fixedly connected to the side wall of the rotating shaft 5, which is located below the filter plate 3. A water inlet 61 is provided on the side wall of the water collecting bucket 6, and a water outlet 62 is provided on the top thereof. The lengths of the water inlet 61 and the water outlet 62 are equal, and the width of the water inlet 61 is greater than the width of the water outlet 62. The collecting plate 7 is fixedly connected to the side wall of the rotating shaft 5. The collecting plate 7 is located above the filter plate 3. The collecting plate 7 is an arc-shaped plate, and the side away from the water collecting bucket 6 is higher than the side close to the water collecting bucket 6. The outer end of the collecting plate 7 is also provided with a water filter hole 71, and the upper surface of the collecting plate 7 is provided with a water diversion groove 72. The water diversion groove 72 is inclinedly distributed, and the end close to the rotating shaft 5 is higher than the end close to the water filter hole 71. The rotating shaft 5 is also slidably matched with a lifting plate 9, and the side wall of the lifting plate 9 is stopped and slidably matched with the inner wall of the shell 1. The bottom of the shell 1 is also provided with a second driving member 10, which is a hydraulic cylinder, and its output end is fixedly connected to the lifting plate 9. The second driving member 10 is used to drive the lifting plate 9 to move up and down, thereby adjusting the liquid level in the shell 1.

[0040] When the first driving member 8 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the water collecting bucket 6 to rotate around the rotating shaft 5. At this time, the liquid level of the cleaning liquid in the shell 1 is higher than the water collecting bucket 6 and lower than the filter plate 3. During the rotation of the water collecting bucket 6, the cleaning liquid will enter the water collecting bucket 6 from the water inlet 61. During the rotation, the water collecting bucket 6 can squeeze the cleaning liquid in the water collecting bucket 6, so that the cleaning liquid in the water collecting bucket 6 forms a high-speed water flow and is sprayed out from the water outlet 62, flushing the filter plate 3 from bottom to top, and carrying impurities on the filter plate 3 to fall on the collecting plate 7.

[0041] like Figures 3 to 7As shown, a movable groove 11 is provided below the collecting plate 7, and the movable groove 11 is elastically connected to the collecting plate 7 through a first elastic member, which is a spring. The movable groove 11 can move up and down relative to the collecting plate 7, and a movable plate 12 is provided in the movable groove 11, and the movable plate 12 is elastically connected to the movable groove 11 through a second elastic member 121, which is a spring. A first magnet 13 is provided on the movable plate 12, and the side wall of the movable plate 12 is fitted and slidably matched with the inner wall of the movable groove 11, and the movable plate 12 can move up and down in the movable groove 11. A mounting seat 14 is provided on the side wall of the water collecting bucket 6, and a second magnet 15 is rotatably matched in the mounting seat 14, and both the first magnet 13 and the second magnet 15 are strong magnets. A push plate 16 is slidably fitted on the side wall of the water collecting bucket 6. The push plate 16 is elastically connected to the water collecting bucket 6 through a third elastic member 161. The third elastic member 161 is a spring. The push plate 16 can extend into the mounting seat 14. The top end of the push plate 16 abuts against and slidably fits with the filter plate 3. The second magnet 15 is provided with a first gear 151 and a half gear 152. The push plate 16 is provided with a tooth groove corresponding to the first gear 151. The first gear 151 is meshed with the push plate 16. When the push plate 16 approaches or moves away from the mounting seat 14, it can drive the second magnet 15 to rotate. An annular tooth groove corresponding to the half gear 152 is provided on the bottom surface of the filter plate 3, and the half gear 152 can mesh with the filter plate 3 through the annular tooth groove.

[0042] When the filter plate 3 is completely blocked, the lifting plate 9 is driven up and down by the second driving member 10, so that the liquid level of the cleaning liquid is higher than the filter plate 3 and lower than the collecting plate 7, and the first driving member 8 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the water collecting bucket 6 to rotate around the rotating shaft 5. Since the filter plate 3 is in a blocked state, the cleaning liquid in the water collecting bucket 6 cannot be discharged from the water outlet 62, thereby applying pressure to the push plate 16 and pushing the push plate 16 close to the mounting seat 14. The push plate 16 pushes the second magnet 15 to rotate 180 degrees during the movement, so that the first magnet 13 and the second magnet 15 attract each other. Under the action of magnetic force, the movable groove 11 and the movable plate 12 move downward. At this time, the first elastic member stretches. When the bottom of the movable groove 11 stops with the filter plate 3, the movable plate 12 continues to move downward, and the second elastic member 121 stretches until the movable plate 12 stops with the upper surface of the filter plate 3. At this time, the half gear 152 and the annular tooth groove The second magnet 15 is meshed, the rotating shaft 5 continues to rotate, and the half gear 152 moves along the annular tooth groove, so that the second magnet 15 rotates 180 degrees again. During this process, the second magnet 15 pushes the push plate 16 through the first gear 151 to overcome the resistance of the cleaning liquid and reset until the half gear 152 is out of contact with the annular tooth groove. At this time, the first magnet 13 and the second magnet 15 repel each other. Under the combined action of the repulsive force and the elastic force of the second elastic member 121, the movable plate 12 moves upward rapidly in the movable groove 11, and the impurities in the filter holes of the filter plate 3 corresponding to the movable groove 11 are sucked out by negative pressure. The impurities fall on the filter plate 3, and then the first elastic member contracts, so that the movable groove 11 moves upward and out of contact with the filter plate 3, so as to realize the dredging of the filter holes in the fan-shaped area of ​​the filter plate 3. When the cleaning component rotates one circle and returns to the corresponding position of the filter plate 3, the impurities previously sucked out of the filter holes can be carried to the collecting plate 7 by the recoil of the cleaning liquid.

[0043] like Figure 2 , Figure 8 and Fig. 9 As shown, a slag discharge pipe is provided inside the rotating shaft 5, the slag discharge pipe is fixedly connected to the rotating shaft 5, the bottom end of the slag discharge pipe is connected to the outside, a slag discharge port is provided on the side wall of the rotating shaft 5, the slag discharge port is connected to the slag discharge pipe, and the bottom end of the slag discharge port is flush with the upper surface of the collecting plate 7. The slag discharge port is rotatably matched with an auger blade 17, the auger blade 17 is provided with a second gear 171, the top of the fixed seat 51 is provided with a tooth groove, and the second gear 171 is meshed with the fixed seat 51 through the tooth groove. The lower surface of the auger blade 17 is stopped against the collecting plate 7.

[0044] When the rotating shaft 5 rotates, the second gear 171 moves along the tooth groove at the top of the fixed seat 51, thereby driving the auger blade 17 to rotate. When the cleaning liquid carrying impurities falls on the collecting plate 7, the cleaning liquid moves along the water inlet groove 72 to the water filter hole 71, and passes through the water filter hole 71 and the filter plate 3 back to the bottom of the cylinder. The impurities are gradually moved to the slag discharge port under the push of the auger blade 17, and enter the slag discharge pipe from the slag discharge port, and then discharged to the outside through the slag discharge pipe.
