[0034] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely expressed in combination with the drawings in the embodiments of the present invention. The embodiments expressed in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the present invention.

[0035] like Figures 1 to 13 As shown, the high-efficiency waste gas treatment equipment described in the present invention comprises:

[0036] The hollow dust removal container 2 has activated carbon sheets 58, porous ceramic sheets 59, charcoal screens 60 and coke screens 61 arranged from high to low in the dust removal container 2, which perform dust removal treatment on the exhaust gas in sequence so that it meets environmental protection requirements and is sent out to the discharge channel. The lower part of the dust removal container 2 is connected to the annular columnar discharge channel; the discharge channel is connected to the hollow area in the dust removal container 2.

[0037] The high-efficiency exhaust gas treatment equipment also includes a hollow pre-treatment container 3, which is connected to the dust removal container 2 via a cylindrical exhaust gas channel 4. A top-extrusion dust removal part is installed in the pre-treatment container 3, and the top-extrusion dust removal part includes a rectangular top sheet 5 and a dust removal side sheet 6. The cross-section of the hollow area of ​​the pre-treatment container 3 can be rectangular, and the top sheet 5 can run vertically on the pre-treatment container 3. A pair of mirror-image side walls of the top sheet 5 are attached to the inner surface of the pre-treatment container 3, and the other two side walls of the top sheet 5 are movably connected to the dust removal side sheet 6. A gap 7 is formed between the end of the dust removal side sheet 6 farther from the top sheet 5 and the inner surface of the pre-treatment container 3, and both sides of the dust removal side sheet 6 are attached to the side walls of the pre-treatment container 3. The top sheet 5 A cylindrical plastic air supply channel 8 is arranged on the top, one end of which is connected to the exhaust channel 4, and the other end of which is accompanied by the top plate 5. A pneumatic piston 44 is vertically arranged on the upper wall of the front disposal container 3, and the piston rod of the pneumatic piston 44 is connected to the top plate 5. A stepped operating port 45 is provided on the upper wall of the front disposal container 3, and a stepped sealing head 46 is matched and filled in the stepped operating port 45. The stepped sealing head 46 is connected to the front disposal container 3 through a pin rod. A sealing piece 47 is fixed on the step of the stepped operating port 45. The stepped sealing head 46 pushes the sealing piece 47 to form a considerable strain, so that one end of the plastic air supply channel 8 is tied to the piston rod of the pneumatic piston 44, so that The plastic channel 8 for air delivery can be operated along with the top sheet 5 to transfer the waste gas. A cylindrical air inlet channel connected to the inside of the pre-treatment container 3 is arranged on one side of the pre-treatment container 3, and an air suction motor is arranged on the air inlet channel. The air inlet channel is used to be connected to the cylindrical air outlet channel on the waste gas tank (the air outlet channel is connected to the hollow interior of the waste gas tank, and the waste gas to be treated is stored in the waste gas tank) through a flange. By starting the air suction motor, the waste gas with particulate dust in the waste gas tank can be delivered to the pre-treatment container 3 through the air inlet channel. When the waste gas is delivered to the pre-treatment container 3, the pneumatic piston 44 pulls the top sheet 5 to run above the air inlet channel, so that the particulate dust in the exhaust gas is under the top sheet 5. Then, the pneumatic piston 44 pulls the top sheet 5 runs downward to squeeze the exhaust gas, and the exhaust gas surges to the top plate 5 through the gap 7. An exhaust motor is installed on the exhaust gas channel 4, and the exhaust gas from the pre-treatment container 3 is transmitted to the dust removal container 2 through the exhaust motor. Because the air supply plastic channel 8 can run along with the top plate 5, the air supply plastic channel 8 can run along with the surge of the exhaust gas, and can better transmit the exhaust gas with the particulate dust removed to the dust removal container 2, and the particulate dust is blocked under the top plate 5, and the particulate dust is squeezed by the top plate 5 to gather the particulate dust, so as to perform pre-treatment on the exhaust gas before sending it into the dust removal container 2, remove the particulate dust in the exhaust gas, reduce the hidden danger of the dust removal container 2 being blocked, and increase the working life of the dust removal container.

One end of the lower sheet is attached to the inner surface of the front disposal container 3, and the other end of the lower sheet is connected to the piston rod of the pneumatic piston 44 after passing through the front disposal container 3. After the granular dust is squeezed and gathered, the lower sheet is moved outward to allow the granular dust squeezed and gathered on the lower sheet to be discharged through the front disposal container 3. To ensure the sealing function, the periphery of the lower sheet is wrapped with a sealing piece of PTFE material, and the sealing piece is attached to the inner surface of the front disposal container 3 in a top-extrusion state to achieve a good sealing function.

[0039] In a preferred but non-limiting embodiment of the present invention, the outer surfaces of the activated carbon sheet 58 , the porous ceramic sheet 59 , the charcoal grid 60 and the coke screen 61 are all tightly engaged with the inner surface of the dust removal container 2 .

[0040] In a preferred but non-restrictive embodiment of the present invention, because some fine dust will be sent to the dust removal container 2 through the gap 7, a dust removal part is installed in the dust removal container 2, and the dust removal part is located on the activated carbon sheet 58. The dust removal part includes a rectangular ring 9 tightly engaged with the inner surface of the dust removal container 2, a left-right screen wire 10 and a front-back screen wire 21, and a plurality of left-right screen wires 10 are densely arranged horizontally from left to right in the rectangular ring 9, and a plurality of front-back screen wires 21 are densely arranged horizontally from front to back in the rectangular ring 9, and the left-right screen wires 10 and the front The rear screen wire 21 is a dust removal grid formed by vertically sticking to each other. One end of the left and right screen wire 10 and one end of the front and back screen wire 21 are fixedly connected to the rectangular ring 9, and the other end of the left and right screen wire 10 and the other end of the front and back screen wire 21 are movable. The exhaust gas sent into the dust removal container 2 is first screened out of the fine dust in the exhaust gas through the dust removal part, thereby improving the dust removal and management function of the exhaust gas, reducing the hidden danger of blockage of the activated carbon sheet 58, the porous ceramic sheet 59, the charcoal grid 60 and the coke screen 61, and increasing the service life of the activated carbon sheet 58, the porous ceramic sheet 59, the charcoal grid 60 and the coke screen 61.

[0041] In a preferred but non-limiting embodiment of the present invention, the left and right screen wires 10 and the front and back screen wires 21 have two modes, namely, a straightening mode and a sagging mode. When dust removal is performed on the exhaust gas, the left and right screen wires 10 and the front and back screen wires 21 are in the straightening mode. When the dust removal part is to be turned on, the left and right screen wires 10 and the front and back screen wires 21 are in the sagging mode, which can efficiently achieve the unobstructed and clean state of the dust removal part.

[0042] In a preferred but non-restrictive embodiment of the present invention, the upper surface of the dust removal container 2 is open, the upper surface of the dust removal container 2 is connected to the cover body 52, the inner surface of the dust removal container 2 is fixedly connected to the annular protrusion 53, the rectangular ring member 9 is pinned to the annular protrusion 53 via a pin rod, and an annular groove 54 is opened between the inner and outer surfaces of the rectangular ring member 9, and the left and right rollers 55 (the center line of the left and right rollers 55 is horizontal to the left and right) and the front and back rollers 56 (the center line of the front and back rollers 56 is horizontal to the front and back) are rotated in the annular groove 54, the movable end of the front and back screen wires 21 is wound around the left and right rollers 55, the movable end of the left and right screen wires 10 is wound around the front and back rollers 56, and the left and right rollers One end of 55 and one end of the front-rear roller 56 are movably connected to the tensioning screw 57 which is arranged thereon, and the tensioning screw 57 is connected to the thread opening on the rectangular ring 9. The inner surface of the left-right roller 55 and the inner surface of the front-rear roller 56 are provided with guide openings along the center line of the left-right roller 55 and the center line of the front-rear roller 56. The end of the tensioning screw 57 is fixedly connected to the guide piece, and the guide piece is placed in the guide opening. When the dust removal part needs to be cleaned or the dust removal part is blocked and needs to be cleaned, the cover body 52 is opened, the rectangular ring 9 is separated from the circular protrusion 53, and then the tensioning screw 57 on the left-right roller 55 and the front-rear roller 56 is unscrewed, and the left-right roller 55 is pulled to rotate and send out the front-rear screen wire 21 and the front screen wire 21. The rear roller 56 rotates to send out the left and right screen wires 10, so that the front and rear screen wires 21 and the left and right screen wires 10 are in a loose mode, so that the obstructions between the front and rear screen wires 21 and the left and right screen wires 10 can be efficiently cleaned, and the conduction of the dust removal part can be well achieved. After the conduction and sorting are achieved, a pair of tensioning screws 57 are tightened again, and the left and right rollers 55 are rotated in the opposite direction to tighten the front and rear screen wires 21, and the front and rear rollers 56 are rotated in the opposite direction to tighten the left and right screen wires 10, so that the left and right screen wires 10 and the front and rear screen wires 21 are in a straightening mode again, and then the rectangular ring 9 is installed on the annular protrusion 53; the tensioning screw 57 is used to pull the left and right rollers 55 and the front and rear rollers 56 to rotate , so that after the tensioning screw 57 is tightened, it can clamp the location of the left and right rollers 55 and the front and back rollers 56 through its thread mouth, ensuring that the front and back screen wires 21 and the left and right screen wires 10 can always maintain the straightening mode, and the operation of the tensioning screw 57 is to move inward, and the left and right rollers 55 and the front and back rollers 56 are all rotating. It is necessary to prevent mutual interference between the left and right rollers 55 and the tensioning screw 57, and between the front and back rollers 56 and the tensioning screw 57, so that the left and right rollers 55 and the tensioning screw 57, and between the front and back rollers 56 and the tensioning screw 57 can all move, that is, the floating structure of the guide plate and the guide mouth, so that the tensioning screw 57 can pull the left and right rollers 55 and the front and back rollers 56 to rotate without the defect of mutual interference.

[0043] In a preferred but non-restrictive embodiment of the present invention, both ends of the top sheet 5 are provided with rectangular strip openings 22, the strip openings 22 penetrate the two sides of the top sheet 5, the dust removal side sheet 6 is placed in the strip openings 22, the end of the dust removal side sheet 6 farther from the front disposal container 3 is fixedly connected to a floating roller 23, the floating roller 23 is movably arranged on the top sheet 5, a hollow chamber 24 is opened in the top sheet 5, one end of the floating roller 23 extends into the hollow chamber 24 and is fixedly connected to a worm 25, a pair of worms 25 connected to the dust removal side sheet 6 are arranged facing each other, a roller body 27 is arranged between the pair of worms 25, the roller body 27 is screwed to the top sheet 5, and the roller body 27 is arranged on the roller body 27. The hoop is connected to the worm gear 28, and a pair of worms 25 are engaged with the worm gear 28. The upper surface of the top sheet 5 is provided with a circular opening 29, and a columnar sheet 30 is movably arranged in the circular opening 29. The roller body 27 is fixedly connected to the columnar sheet 30, and a hexagonal columnar opening is provided on the head wall of the columnar sheet 30 farther from the roller body 27. A circular sealing sheet 31 of PTFE material is arranged between the columnar sheet 30 and the lower surface of the circular opening 29, and the circular sealing sheet 31 is squeezed into a compressed state by the columnar sheet 30. Before the pre-treatment of the exhaust gas is performed, the position of the dust removal side sheet 6 is first configured, and the pneumatic piston 44 pulls the top sheet 5 to run close to the upper surface of the pre-treatment container 3. Next, remove the terraced end cap 46, operate the columnar sheet 30 through the terraced operating port 45, use a tool such as a wrench to pull the columnar sheet 30 to rotate, the columnar sheet 30 pulls the roller body 27 to rotate, the roller body 27 pulls the worm wheel 28 to rotate, the worm wheel 28 pulls the pair of worms 25 to run linearly, the worm 25 pulls the dust removal edge sheet 6 to run through the movable roller 23, because the pair of worms 25 are arranged facing each other, the running directions of the pair of worms 25 are opposite, so that the running directions of the pair of dust removal edge sheets 6 are opposite, and the gap 7 formed by the pair of dust removal edge sheets 6 can be changed together, and the dust removal can be achieved by only rotating the columnar sheet 30 remotely. The change of the dust removal edge piece 6 is convenient to operate and has a wide range of uses. After the position change of the dust removal edge piece 6 is completed, the stepped head 46 can be installed again. The stepped head 46 pushes the closing piece 47 to make it produce a considerable strain, which can well close the stepped operation port 45 to prevent the defect of exhaust gas leakage. The gap between the circular port 29 and the columnar piece 30 is sealed through the annular closing piece 31, and the closing ring of the PTFE material is clamped on the movable roller 23. The closing ring of the PTFE material is statically matched with the top piece, thereby improving the sealing of the hollow chamber 24, making it difficult for the exhaust gas to be sent into the hollow chamber 24.

[0044] In a preferred but non-restrictive embodiment of the present invention, the above structure cannot perform positioning on the roller body 27, because the dust removal side piece 6 needs to push the granular dust. Therefore, there is a considerable pushing force between the dust removal side piece 6 and the granular dust, which will exert force to pull the dust removal side piece 6 to run. In addition, the exhaust gas surges through the gap 7, which will push the dust removal side piece 6 to run close to the top piece 5. Therefore, the size of the gap 7 cannot be maintained constantly. Therefore, a pair of toothed disc positioning parts are installed in the hollow chamber 24, and the pair of toothed disc positioning parts are arranged along the vertical cross of the top piece 5.

[0045] In a preferred but non-limiting embodiment of the present invention, the tooth plate positioning portion includes a tooth plate 32, a roller member 33, a curved wedge block 34 and a positioning strip 35. The tooth plate 32 is hooped on the roller body 27. A plurality of curved protruding teeth are evenly and densely distributed on the circumferential wall of the tooth plate 32. Each protruding tooth has the same shape and the same bending direction. The roller member 33 can run vertically along the top plate 5. The wedge block 34 is hooped on the roller member 33 via a disc spring. The positioning strip 35 is fixed to the top plate 5. When the disc spring is not rotated, the wedge block 34 is inserted into the tooth plate. The tooth space between the protruding teeth of the toothed disc 32 and the positioning strip 35 are attached to the inner side wall of the wedge block 34 to achieve the function of unidirectional positioning. The rotation direction of the toothed disc 32 in the pair of toothed disc positioning parts is opposite. The toothed disc positioning part also includes a guide roller 26, one end of the guide roller 26 is fixedly connected to the top plate 5, and the other end of the guide roller 26 has a columnar opening 36, and a tension spring 37 is installed in the columnar opening 36. One end of the roller member 33 is placed in the columnar opening 36, and the two ends of the tension spring 37 are respectively connected to the roller member 33 and the guide roller 26. The side of the columnar opening 36 The wall is provided with a guide opening 38 extending along the center line of the columnar opening. The side wall of the roller member 33 is fixedly connected to a movable piece 39. The movable piece 39 is placed in the guide opening 38. When the tension spring 37 is not stressed, the wedge block 34 penetrates into the protruding teeth of the tooth plate 32. Because the rotation directions of the tooth plates 32 in the pair of tooth plate positioning parts are opposite to each other, the pair of tooth plate positioning parts respectively position the pair of rotation directions of the roller body 27. That is, when the tooth plate 32 in the tooth plate positioning part and the wedge block 34 are combined, the roller body 27 is restricted from rotating from the right to the left. When the toothed disc 32 and the wedge block 34 in the other toothed disc positioning part are combined, the rotation of the roller body 27 from left to right is restricted, but the rotation of the roller body 27 from right to left is not interfered. Because the wedge block mechanism has a single-direction positioning function, in order to position the roller body 27 for two-way rotation, the present application introduces a pair of toothed disc positioning parts arranged inversely to position the rotation of the roller body 27, thereby positioning the direction of the dust removal edge sheet 6 to ensure the constancy of the gap 7;Here, the rotation of the roller body 27 from right to left is defined as the dust removal side piece 6 running away from the top piece 5, and the rotation of the roller body 27 from left to right is defined as the dust removal side piece 6 running close to the top piece 5. When the gap 7 is to be enlarged, the roller body 27 is rotated from left to right to compress the roller member 33 in the toothed plate positioning part that restricts the rotation of the roller body 27 from left to right, so that the roller member 33 compresses the tension spring 37 to run toward the guide roller 26, and the roller member 33 pulls the wedge block 34 to run downward and the corresponding The toothed disc 32 is separated, so that the toothed disc 32 stops the positioning function, because the other toothed disc positioning part does not interfere with the rotation of the roller body 27 from left to right, so there is no need to perform the configuration, and the rotating columnar sheet 30 can pull the roller body 27 to rotate from left to right, because the rotation interval of the roller body 27 from right to left is restricted by the other toothed disc positioning part, so that the roller body 27 can only rotate in one direction, that is, from left to right, and the wrong rotation cannot occur, so that the dust removal edge sheet 6 is more correct. After the change is achieved, the roller 33 is released, and the roller 33 is restored upward under the reverse force of the tension spring 37, so that the wedge 34 on it is combined with the toothed disc 32 again to restrict the roller body 27 from rotating from left to right. When the gap is to be reduced, the roller body 27 is rotated from right to left to press the roller 33 in the toothed disc positioning part that restricts the roller body 27 from rotating from right to left, so that the wedge 34 on the roller 33 and the corresponding toothed disc 32 are separated. Then, the columnar sheet 30 is rotated to pull the roller body 27 to rotate from right to left, so as to change the gap 7. In short, the rotation interval of the roller body 27 is restricted by a pair of toothed plate positioning parts. When the roller body 27 is to be rotated from right to left or from left to right to change the gap 7, it is only necessary to release the toothed plate positioning parts that restrict the positioning from right to left or from left to right. The operation is convenient, and the restriction function of the roller body 27 is good, ensuring the constant position of the dust removal edge sheet 6.

[0046] In a preferred but non-limiting embodiment of the present invention, when it is difficult for the worker to maintain the operation of the pressing roller 33, the worker can also rotate the columnar sheet 30 to pull the roller body 27 to rotate, so that an inner thread opening 40 is opened on the upper surface of the top sheet 5 relative to the location of the roller 33, and a through-opening 41 is opened on the lower surface of the inner thread opening 40. The closed ring 31 of the PTFE material is fixedly connected to the through-opening 41, and the end of the roller 33 farther from the guide roller 26 extends through the closed ring 31 to the inner thread opening 40. In the opening 40, the closing ring 31 is statically matched with the roller member 33 through its own strain. The inner thread opening 40 is threaded with a columnar member 43 with an outer thread opening on the outer surface. The columnar member 43 is used to press the roller member 33 to separate the wedge block 34 and the tooth plate 32. The head wall of the columnar member 43 farther from the roller member 33 is provided with a hexagonal columnar opening. The columnar member 43 is threadedly connected to the inner thread opening 40. The threaded structure can locate the position of the columnar member 43. When the tooth plate positioning part here is to be changed, the corresponding The columnar member 43 corresponding to the toothed disc positioning part is rotated to allow the columnar member 43 to move close to the roller member 33. The columnar member 43 pushes the roller member 33 downward to separate the wedge block 34 on the roller member 33 from the toothed disc 32. The thread connection of the columnar member 43 can position the columnar member 43, thereby positioning the roller member 33. The worker does not need to press the roller member 33 all the time. After the columnar member 43 is in place, it is only necessary to rotate the columnar sheet 30 again to allow the columnar member 43 to move. The operation of the cylindrical piece 30 can be executed independently in sequence, reducing the complexity of the operation. After the position change of the dust removal edge piece 6 is achieved, the cylindrical piece 43 is rotated upward to allow the roller piece 33 to be restored under the reverse force of the tension spring 37, so that the wedge block 34 on the roller piece 33 is combined with the toothed disc 32 again to achieve the positioning of the roller body 27; the introduction of the closing ring 31 shields the gap between the through-hole 41 and the roller piece 33, improves the closing force, and the cylindrical piece 43 can also achieve a closing effect.

[0047] In a preferred but non-restrictive embodiment of the present invention, when the top sheet 5 pushes the granular dust, driven by the airflow, the granular dust will be blocked in the gap 7 and will scale on the side wall of the dust removal side sheet 6. Therefore, a strip channel 48 is opened on the side wall of the gap 7 formed by the front disposal container 3 and the dust removal side sheet 6, and a tidying tension spring 49 is installed in the strip channel 48. A cleaning sheet 50 is movably connected in the strip channel 48. The two ends of the tidying tension spring 49 are respectively connected to the front disposal container 3 and the cleaning sheet 50. The end of the cleaning sheet 50 farther from the tidying tension spring 49 extends into the front disposal container 3. The upper and lower surfaces of the end of the cleaning sheet 50 farther from the tidying tension spring 49 are provided with inclined walls 51. When the gap 7 is blocked or the granular dust scales on the dust removal side sheet 6, the top sheet 5 moves upward, and the dust removing side sheet 6 pushes the lower inclined wall 51 of the cleaning sheet 50. Driven by the lower inclined wall 51, the cleaning sheet 50 presses the tidying tension spring 49 to move into the strip-shaped channel 48, so that the end of the cleaning sheet 50 farther from the tidying tension spring 49 can be attached to the side wall of the dust removing side sheet 6. Under the reverse force of the tidying tension spring 49, there is a considerable fitting force between the cleaning sheet 50 and the top sheet 5, and the top sheet 5 then moves upward, so as to peel off the granular dust on the side wall of the dust removing side sheet 6 through the cleaning sheet 50, so as to clean the dust removing side sheet 6. When the top sheet 5 moves downward, driven by the inclined wall 51 on the upper wall of the cleaning sheet 50, the dust removing side sheet 6 can smoothly pass through the cleaning sheet 50, thereby achieving the function of pushing the granular dust.

[0048] The beneficial function of the present invention is that, compared with the prior art, the present invention allows the waste gas of granular dust to be first sent into the pre-treatment container, the waste gas is squeezed through the top sheet, and the waste gas is dusted through the gap, so that the waste gas surges to the top of the top sheet through the gap, and the airflow after dust removal is sent to the dust removal container through the air delivery plastic channel and the waste gas channel, while the granular dust is maintained under the top sheet, and the granular dust is squeezed through the top sheet to gather the granular dust, so that the waste gas is pre-treated before being sent into the dust removal container, the granular dust in the waste gas is removed, and the hidden danger of the dust removal container being blocked is reduced. , increasing the service life of the dust removal container; because some fine dust will be sent to the dust removal container through the gap, so before the exhaust gas is subjected to dust removal treatment, the fine dust in the exhaust gas is first screened out through the dust removal part to improve the dust removal and management function of the exhaust gas. The left and right screen wires and the front and back screen wires have two modes, namely the straightening mode and the drooping mode. When the exhaust gas is subjected to dust removal, the left and right screen wires and the front and back screen wires are in the straightening mode. When the dust removal part is to be turned on, the left and right screen wires and the front and back screen wires are in the drooping mode, which can efficiently achieve the unobstructed and clean state of the dust removal part.
