DETAILED DESCRIPTION

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043] Embodiment 1: A waste gas purifier for chemical production, such as Figures 1 to 9As shown, it includes a purifier body 1, an air inlet pipe 11 is connected to the upper left side of the purifier body 1, a transparent window 12 is fixedly connected to the right front side of the purifier body 1 for observing the internal situation of the purifier body 1, a rotating door is rotatably connected to the left front side of the purifier body 1 for easy maintenance of the inside of the purifier body 1, an air outlet pipe 13 is connected to the lower right side of the purifier body 1, a mounting plate frame 14 is fixedly connected to the right inside the purifier body 1, the inside of the mounting plate frame 14 is used as a purification unit to purify the exhaust gas, and an activated carbon adsorption plate 14 is fixedly connected to the upper side of the inside of the mounting plate frame 14 01, a metal oxide catalyst layer 1402 is fixedly connected to the middle of the mounting plate frame 14, a photocatalytic reaction layer 1403 is fixedly connected to the lower side of the mounting plate frame 14, a mounting shell 15 is fixedly connected to the left part of the purifier body 1, the mounting shell 15 is used as a pre-treatment unit to remove dust and water from the exhaust gas, the upper and lower sides of the mounting shell 15 are fixedly connected to dust removal plates 1501, the dust removal plates 1501 are umbrella-shaped, and two water absorption plates 1502 are fixedly connected to the mounting shell 15, and the water absorption plate 1502 is located between the two dust removal plates 1501, A guide tube 1503 is connected between the top of the mounting plate frame 14 and the bottom of the mounting shell 15. A collecting shell 17 is fixedly connected to the lower left part of the interior of the purifier body 1. A collecting bucket 16 for collecting dust is placed in the collecting shell 17. A plurality of filter holes are opened at the bottom of the collecting bucket 16. The collecting shell 17 is connected to an air guide tube 18 symmetrically distributed along the front and rear of the collecting shell 17. A collecting frame 19 is fixedly connected to the mounting shell 15. The collecting frame 19 longitudinally penetrates the water absorption plate 1502. The collecting frame 19 is used to collect dust on the two dust removal plates 1501. The inner wall on the left side of the purifier body 1 A dust suction pump 110 is fixedly connected to the lower part, the top side of the dust suction pump 110 is connected to the collecting frame 19, the bottom side of the dust suction pump 110 is connected to the collecting shell 17, a cavity frame 111 is fixedly connected to the side of the mounting shell 15 close to the air inlet pipe 11, the air guide pipe 18 is connected to the cavity frame 111, the cavity frame 111 and the air inlet pipe 11 are connected through two one-way pipes, the one-way pipe limits the exhaust gas in the cavity frame 111 to flow into the air inlet pipe 11 in one direction, the air guide pipe 18 is fixedly connected to a one-way valve 112, the one-way valve 112 limits the exhaust gas in the collecting shell 17 to flow into the cavity frame 111 in one direction.

[0044] When the exhaust gas purifier is turned on, the exhaust gas enters the installation shell 15 from the air inlet pipe 11, passes through the upper dust removal plate 1501, the water absorption plate 1502 and the lower dust removal plate 1501 in turn for multiple dust removal and water removal pretreatment to reduce the burden of the subsequent purification unit, and then enters the installation plate frame 14 through the guide pipe 1503, and then passes through the activated carbon adsorption plate 1401, the metal oxide catalyst layer 1402 and the photocatalytic reaction layer 1403 in turn. The activated carbon adsorption plate 1401 can effectively absorb organic matter and some inorganic matter in the exhaust gas, and the metal The oxide catalyst layer 1402 can catalytically oxidize harmful substances in the exhaust gas at a relatively low temperature and convert them into harmless substances. The photocatalytic reaction layer 1403 uses light energy to excite the catalyst to undergo an oxidation-reduction reaction with harmful substances in the exhaust gas and convert them into harmless substances. In this way, after the exhaust gas undergoes multiple composite purification treatments, the harmful substances therein can be largely removed, thereby improving the purification efficiency and stability of the exhaust gas. The exhaust gas that has been pretreated and purified is finally discharged through the exhaust pipe 13. After the exhaust gas treatment is completed, the exhaust gas purifier is turned off.

[0045] When the exhaust gas purifier is started, the dust suction pump 110 is started at the same time. Under the action of suction, the dust blocked by the dust removal plate 1501 slides down the curved surface into the collection rack 19, and then is sucked into the collection bucket 16 by the dust suction pump 110 to achieve the effect of collecting dust. When the dust in the collection bucket 16 accumulates to a certain extent, the rotating door of the purifier body 1 is opened, and the collection bucket 16 is pulled forward to remove the collection bucket 16 for cleaning. After cleaning, the collection bucket 16 is put back in place.

[0046] During the dust suction process of the dust suction pump 110, a small amount of exhaust gas will be sucked into the collecting bucket 16 together with the dust. The dust will remain in the collecting bucket 16, and the exhaust gas will enter the air duct 18 through the filter holes of the collecting bucket 16 and then go up into the cavity frame 111, and then flow back into the air intake pipe 11. The one-way valve 112 prevents the exhaust gas from flowing back. In this way, this part of the exhaust gas can be pre-treated for a second time to improve the exhaust gas treatment effect.

[0047] like Fig.10 As shown, it also includes two mounting frames 23, and the two mounting frames 23 are respectively fixedly connected in the mounting shell 15, and the bottom of the mounting frames 23 is fixedly connected with the circumferentially distributed second pull ropes 25, and the connecting frame 21 is fixedly connected between the circumferentially distributed second pull ropes 25 on the same side, and the bottom of the connecting frame 21 is fixedly connected with the circumferentially distributed first pull ropes 22, and the first pull ropes 22 are fixedly connected with the knocking block 2, and the knocking block 2 is in contact with the adjacent dust removal plate 1501, and is used to shake off the dust on the dust removal plate 1501, and three guide plates 24 are fixedly connected to the connecting frame 21, and the guide plates 24 are wavy.

[0048] Since the dust on the dust removal plate 1501 is subjected to the downward pressure of the exhaust gas, it is difficult for it to slide into the collection rack 19, which affects the collection of dust. To assist the dust in sliding down, the specific operation is as follows: When the exhaust gas enters the mounting plate frame 14, it will first pass through the guide plate 24. Under the action of the guide plate 24, the exhaust gas blows the connecting frame 21, causing the connecting frame 21 to shake, thereby driving the knocking block 2 to shake through the first pull rope 22. The surface of the dust removal plate 1501 is knocked irregularly, and the dust accumulated on the dust removal plate 1501 is effectively shaken into the collection rack 19.

[0049] like Figures 11 to 13 As shown, it also includes a fixed plate 3, which is fixedly connected to the inner rear side of the collecting bucket 16, and a baffle 31 is fixedly connected to the front of the collecting shell 17. The collecting bucket 16 is slidably connected to the magnetic plate 32 along the front and rear directions. When the collecting bucket 16 is pulled forward, the fixed plate 3 moves forward with the collecting bucket 16 and magnetically cooperates with the magnetic plate 32. The magnetic plate 32 and the baffle 31 are magnetically cooperated. A folding frame 33 is fixedly connected to the front side of the collecting bucket 16, and a cover cloth 34 is fixedly connected between the magnetic plate 32 and the folding frame 33. The cover cloth 34 is used to cover the collecting bucket 16 when the collecting bucket 16 is pulled forward.

[0050] When taking out the collecting bucket 16, in order to prevent the dust in the collecting bucket 16 from flying everywhere, the collecting bucket 16 needs to be covered. The specific operation is as follows: when the collecting bucket 16 is pulled forward, the collecting bucket 16 drives the gathering frame 33 to move forward, thereby driving the gathering frame 33 to move forward together. Since the magnetic plate 32 is adsorbed by the baffle 31, the magnetic plate 32 is stationary. In this way, the side of the cover cloth 34 fixedly connected to the magnetic plate 32 does not move, and the side fixedly connected to the gathering frame 33 moves forward with the gathering frame 33, so that the cover cloth 34 gradually unfolds and covers the collecting bucket 16. In addition, the fixed plate 3 moves forward with the collecting bucket 16. When the fixed plate 3 moves to contact with the magnetic plate 32, the magnetic plate 32 is adsorbed on the fixed plate 3 to fix the magnetic plate 32, thereby fixing the back side of the cover cloth 34.

[0051] When the collecting bucket 16 is put back to its original position, the magnetic plate 32 will stop moving due to the action of the baffle 31, and the folding frame 33 and the fixed plate 3 will move backwards together with the collecting bucket 16. In this way, the fixed plate 3 is separated from the magnetic plate 32, and the side of the cover cloth 34 fixedly connected to the magnetic plate 32 remains stationary, and the side fixedly connected to the folding frame 33 moves backwards together with the folding frame 33, so that the cover cloth 34 is gradually folded and folded, and the collecting bucket 16 is opened to collect dust.

[0052] Embodiment 2: Based on embodiment 1, Figure 14 to Figure 15As shown, six rotating shafts 41 are also included, and every three rotating shafts 41 are rotatably connected to a mounting frame 23. The rotating shafts 41 are fixedly connected to the rotating blades 4 symmetrically distributed along the rotating shafts 41. The rotating shafts 41 are fixedly connected to the turbulence frames 42, and the turbulence frames 42 are wound around the corresponding rotating shafts 41 like springs.

[0053] When the exhaust gas enters the mounting plate frame 14, it drives the rotating blades 4 to rotate, thereby driving the turbulence frame 42 to rotate through the rotating shaft 41, so that the exhaust gas is disturbed and dispersed. In this way, the exhaust gas can blow the guide plate 24 more evenly, enhancing the effect of shaking off the dust on the dust removal plate 1501.

[0054] Embodiment 3: Based on embodiment 2, Figure 16 to Figure 17 As shown, it also includes a storage tank 5 symmetrically distributed along the front and back of the cavity frame 111, and fluorescent powder or other pigment powder can be stored in the storage tank 5. The storage tank 5 is connected to the cavity frame 111, and the storage tank 5 is connected to the discharge block 51 through the guide pipe 53. The cavity frame 111 is rotatably connected to the impeller 52 symmetrically distributed along the front and back of the cavity frame 111, and the impeller 52 has circumferentially distributed grooves, and the discharge block 51 is in contact with the adjacent impeller 52.

[0055] The storage tank 5 is pre-filled with fluorescent powder, and part of the exhaust gas entering the cavity frame 111 through the air guide pipe 18 will blow the impeller 52 to rotate, so that the groove on the outer periphery of the impeller 52 intermittently rotates to the bottom of the discharge block 51, and the fluorescent powder in the storage tank 5 falls into the groove of the impeller 52 through the guide pipe 1503 and the discharge block 51 in turn. When the groove of the impeller 52 turns away from the discharge block 51, the fluorescent powder carried by the groove of the impeller 52 floats into the exhaust gas in the cavity frame 111, and is collected and processed together with the dust in the exhaust gas. Under ultraviolet light, if the gas discharged through the outlet pipe 13 has no fluorescent color or a lighter fluorescent color, and there is a lot of fluorescent powder in the collecting bucket 16, it indicates that the purification effect of the exhaust gas purifier is good. If the gas discharged through the outlet pipe 13 has a darker fluorescent color, or there is no fluorescent powder or very little fluorescent powder in the collecting bucket 16, it indicates that the purification effect is poor, and it is necessary to promptly check the problem and perform maintenance and replacement.

[0056] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above-mentioned embodiments, but should be determined not only by the appended claims, but also by the equivalents of the appended claims.
