[0002] Waste gas recovery and energy-saving equipment refers to environmental protection equipment that uses physical, chemical, or thermal energy conversion technologies to recover and reuse the waste gas emitted during industrial production, while reducing energy consumption.

[0003] Current energy-saving waste gas recovery and utilization equipment on the market collects gas through the inlet, pre-treats it by filtering through a filter component inside the inlet, and finally discharges it through the outlet for subsequent harmless treatment and reuse. Because the waste gas contains impurities such as dust particles, the filter component is easily clogged during filtration, requiring frequent cleaning. Moreover, the dust particles need to be collected and centrally processed to facilitate the reuse of recyclable components. The traditional cleaning method is to directly remove the filter component for cleaning and collect the dust particles, which is inconvenient and wasteful in terms of dust particle collection.

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0013] Example 1: A waste gas pretreatment device includes a recovery and treatment box 1 and a sealing structure 2. An air inlet 11 is provided on one side of the recovery and treatment box 1, and an air outlet 13 is provided on the side opposite to the air inlet 11. A plurality of partition plates 12 are provided inside the recovery and treatment box 1, and each partition plate 12 is provided with a first insertion groove 14. A plurality of air holes are provided through the surface of the partition plate 12. The sealing structure 2 includes a filter structure 23 inserted into the first insertion groove 14. The upper part of the filter structure 23 is connected to the sealing plate 21 on the top of the recovery and treatment box 1. A sealing element is provided between the filter structure 23 and the inner wall of the recovery and treatment box 1. The device also includes a cleaning structure 3 capable of cleaning the filter structure 23. The cleaning structure 3 includes a mounting frame 31 connected to the top of the inner part of the dividing plate 12. A cleaning brush 32 is connected to the bottom of the mounting frame 31. A second insertion slot 33 is provided inside the mounting frame 31. The filter structure 23 is inserted through the second insertion slot 33, and the cleaning brush 32 abuts against the side of the filter structure 23. The cleaning brush 32 is a soft brush design. The first insertion slot 14 includes a first slot 141 and a second slot 142. The first slot 141 is located at the bottom of one side of the second slot 142, and the first slot 141 and the second slot 142 form an "L" shaped slot. The upper part of the filter structure 23 penetrates the sealing plate 21 at the top of the recycling and processing box 1, and the filter structure 23 is movably connected to the sealing plate 21.

[0014] like Figure 1-5 As shown, a waste gas pretreatment device includes a recovery and treatment box 1, dividing plates 12, a first insertion groove 14, a first-stage groove 141, a second-stage groove 142, a sealing structure 2, a filter structure 23, and a cleaning structure 3. The recovery and treatment box 1 is provided with a plurality of dividing plates 12. The recovery and treatment box 1 has a chamber for waste gas filtration and reuse, which facilitates the placement of the filter structure in the recovery and treatment box 1. The dividing plates 12 are equidistantly distributed in the recovery and treatment box 1, and the dividing plates 12 and the recovery and treatment box 1 can be welded or detachably connected in the recovery and treatment box 1 by bolts or the like. The plane where the highest point of the dividing plate 12 is located is lower than the plane where the highest point of the recovery and treatment box 1 is located. The surface of the dividing plate 12 has air holes, and each dividing plate 12 is provided with a first insertion groove 14. The first insertion groove 14 and the dividing plate 12 are integrated into one piece.

[0015] To facilitate the insertion of multi-stage filter plates into the recycling bin 1, the first insertion slot 14 includes a first slot 141 and a second slot 142. Specifically, the first slot 141 is located on one side of the second slot 142, and the first slot 141 and the second slot 142 are connected. The first slot 141 and the second slot 142 are designed in an "L" shape, and the plane where the lowest point of the first slot 141 is located is coplanar with the bottom surface of the recycling bin 1, reducing the probability of garbage accumulation in the first insertion slot 14.

[0016] To facilitate the insertion of the filter structure 23 and the first insertion slot 14, a second-section slot 142 is longitudinally opened inside the dividing plate 12, with the top of the second-section slot 142 extending to the outside of the dividing plate 12, and the filter structure 23 is inserted into the second-section slot 142.

[0017] In order to facilitate the processing of dust and light waste on the surface of the filter structure 23, a first-stage trough 141 is set on one side of the bottom of the second-stage trough 142. The first-stage trough 141 is horizontally connected to the dividing plate 12 and the recycling and processing box 1.

[0018] To facilitate the filtration and cleaning of the exhaust gas inside the recycling and treatment box 1, a portion of the sealing structure 2 is installed inside the recycling and treatment box 1. The sealing structure 2 includes a filter structure 23. Specifically, the filter structure 23 is inserted into the first insertion slot 14, and the top of the filter structure 23 extends above the top sealing plate 21 of the recycling and treatment box 1. The filter structure 23 includes an outer frame 4 and a dust particle filter screen 5 (such as filter cloth, non-woven fabric, glass fiber, HEPA, nylon, or other materials capable of filtering gaseous dust particles) fixed inside the outer frame 4. A cover plate 6 is installed on the top of the outer frame 4, located outside the recycling and treatment box 1. A sealing gasket is installed between the bottom of the cover plate 6 and the sealing plate 21. 6. The sealing plate 21 can be left unfixed or fixed with bolts for better sealing. Specifically, the filter structure 23 is inserted into the second-stage groove 142 in the dividing plate 12. After the filter structure 23 is inserted into the bottom of the second-stage groove 142, the exhaust gas will be filtered multiple times at multiple outlets 13 through the air holes of the dividing plate 12. When the filter structure 23 is replaced, the filter structure 23 is pulled. At this time, the filter structure 23 will be peeled off by the cleaning structure 3 on both sides, and the dust and light garbage on the surface will fall into the second-stage groove 142 and enter the recycling and treatment box 1 through the first-stage groove 141. When the machine is stopped for maintenance, the dust particles in the recycling and treatment box 1 are cleaned and collected.

[0019] Sealing gaskets are installed at the contact points between the outer frame 4 of the filter structure 23 and the inner side wall and bottom wall of the recycling and processing box 1 to ensure that gas can only pass through the dust particle filter screen 5. From the air inlet 11 to the air outlet 13, the precision of the dust particle filter screens of the three filter structures 2 increases from small to large, that is, the filtration capacity increases sequentially. The use of a graded filtration method results in better filtration effect.

[0020] The effect achieved by the entire embodiment 1 is that the filter structure 23 is inserted into the two-section groove 142 in the partition plate 12. When the filter structure 23 is inserted into the bottom of the two-section groove 142, the exhaust gas will be filtered multiple times through the air holes of the partition plate 12 at multiple air outlets 13. When the filter structure 23 is cleaned, the filter structure 23 is pulled (a handle is set on the top of the cover plate). At this time, the filter structure 23 will be stripped of the surface dust and light garbage under the action of the cleaning structures 3 on both sides and concentrated into the recycling and processing box 1.

[0021] The cleaning structure 3 includes a mounting frame 31 connected to the top of the interior of the partition plate 12, wherein the mounting frame 31 is as follows: Figure 3 The design is rectangular. The bottom of the mounting frame 31 is connected to the top of the partition plate 12. The mounting frame 31 and the partition plate 12 have threaded grooves at corresponding positions. The mounting frame 31 and the partition plate 12 are fixed by the threaded grooves and bolts. After the mounting frame 31 and the partition plate 12 are fixed, the plane where the highest point of the mounting frame 31 is located is coplanar with the plane where the highest point of the recycling and processing box 1 is located. The bottom of the mounting frame 31 is connected to a cleaning brush 32. The cleaning brush 32 is a soft brush design. The cleaning brush 32 abuts against the filter structure 23 and is used to clean both sides of the filter structure 23 (dust particle filter).

[0022] The mounting frame 31 has a second insertion slot 33 for the filter structure 23 to be inserted through it. The width of the second insertion slot 33 is slightly larger than the width of the filter structure 23.

[0023] Example 2: The connection method between the filter structure 23 and the sealing plate 21 on the top of the recycling tank 1 is different from that in Example 1. The recycling tank 1 is provided with a sealing plate 21. The sealing plate 21 is used to close the top of the recycling tank 1 and seal the recycling tank 1. The sealing plate 21 is connected to the recycling tank 1 by bolts. The bottom of the sealing plate 21 and the cover plate on the top of the filter structure 23 are detachably connected by bolts, etc., that is, the bottom of the sealing plate 21 and the top of the filter structure 23 abut against each other.

[0024] An air inlet 11 is provided on one side of the recycling and processing box 1. The air inlet 11 is connected to the exhaust gas conveying pipe. An air outlet 13 and a return air outlet 13 are connected to an external conduit on the side away from the recycling and processing box 1. The conduit has a suction pump. The suction pump at the air outlet 13 is controlled to guide the exhaust gas flow from the air inlet 11 to the air outlet 13.

[0025] Next, the filter structure 23 is inserted into the second-stage groove 142 within the dividing plate 12. After the filter structure 23 is inserted into the bottom of the second-stage groove 142, the exhaust gas will undergo multiple filtration processes at the multiple filter structures 23 through the air holes of the dividing plate 12. When cleaning the filter structure 23, first remove the connecting bolts between the sealing plate 21 and the recycling box 1, lift the sealing plate 21, and simultaneously pull the filter structure 23. At this time, under the action of the cleaning structures 3 on both sides, the filter structure 23 will peel off the surface dust and light waste, which will fall into the second-stage groove 142 and enter the recycling box 1 through the first-stage groove 141. Then, the recycling box 1 is cleaned, and the waste in the recycling box 1 is cleaned simultaneously, thus completing the work.

[0026] Example 3: Unlike Example 1, the filter structure 23 and cleaning structure 3 are different. Specifically, the filter structure 23 includes an outer frame 4, an inner skeleton 7, and a dust particle filter 5 (such as filter cloth, non-woven fabric, glass fiber, HEPA, nylon, or other materials capable of filtering gaseous dust particles). The dust particle filter 5 covers the inner skeleton 7, and the outer frame 4 and the inner skeleton 7 are fixed with screws. The dust particle filter 5 forms a cavity structure with an open top. The filter structure 23 is inserted into the first insertion slot 14. The top of the filter structure 23 extends above the top sealing plate 21 of the recycling and processing box 1, and the outer frame of the filter structure 23 is sealed and fixed to the top sealing plate 21 of the recycling and processing box 1. The top opening of the filter structure 23 is provided with... The cover 8 is detachably fixed to the outer frame 4 (it can be fixed with bolts). The cleaning structure 3 is provided with an air blowing port 9 on the cover. The air blowing port 9 is connected to an air pipe, a valve and an air pump 10. In this embodiment, the air pump 10 is used to supply air. The airflow enters the internal cavity of the filter structure 23 through the air blowing port 9 and blows out from the dust particle filter screen 5 in the opposite direction (the equipment should be stopped when performing this operation, and the air pump should be intermittently controlled during operation. After standing still for a period of time, the bottom opening of the recycling box 1 is opened to discharge the dust. The recycling box 1 is provided with a conical collection hopper 34 at the bottom between two adjacent filter structures 23, and a gate 35 is provided at the lower end of the conical collection hopper 34) so ​​that the dust on the dust particle filter screen is removed and falls into the bottom of the recycling box 1.

[0027] This embodiment is more time-saving and labor-saving in use compared to embodiments 1 and 2, because it does not require the active filter structure 23.
