Description

Technical Field

[0001] The present invention relates to the technical field of purifiers, and in particular to a waste gas purifier used in chemical production. Background Art

[0002] Chemical production processes often release waste gases containing harmful chemicals, such as sulfur dioxide, nitrogen oxides, and volatile organic compounds. If these pollutants are released directly into the atmosphere without treatment, they can cause serious environmental pollution, affect air quality, and harm ecological balance and human health. Exhaust gas purifiers can effectively reduce the emission of these pollutants, complying with national environmental protection regulations.

[0003] At present, the patent with publication number CN113856390A discloses a multi-treatment purifier for organic waste gas from a chemical plant, comprising: a shell; a purification mechanism, the purification mechanism being arranged inside the shell; an air suction mechanism, the air suction mechanism being slidably connected to the inside of the shell and connected to the purification mechanism; wherein the purification mechanism comprises: a spray assembly, the spray assembly being arranged inside the shell and connected to the suction mechanism; a purification assembly, the purification assembly being arranged inside the spray assembly and connected to the spray assembly through an exhaust pipe; and a transmission assembly, the transmission assembly being arranged between the suction mechanism and the spray assembly. By arranging the suction mechanism and the purification mechanism, the operation of the suction mechanism can achieve absorption and filtration of the waste gas while cooperating with the purification mechanism, so that the purification mechanism can perform multiple and sufficient purification of the waste gas. However, the dust purified and filtered by the purification mechanism still accumulates and remains in the purifier, and cannot be cleaned in time during the purification process of the purifier.

[0020] The present invention utilizes exhaust gas to make the knocking block shake, so that the surface of the dust removal plate is knocked irregularly, and the dust accumulated on the dust removal plate is effectively shaken into the collection rack, solving the problem that the dust on the dust removal plate is subjected to the downward pressure of the exhaust gas, making it difficult to slide into the collection rack.

[0021] When the collecting bucket is pulled forward, the cover cloth automatically unfolds and covers the collecting bucket, so as to prevent the dust in the collecting bucket from being scattered everywhere when the collecting bucket is taken out.

[0022] The present invention utilizes the exhaust gas to drive the turbulence frame to rotate, so that the exhaust gas is disturbed and dispersed. In this way, the exhaust gas can blow the guide plate more evenly, thereby enhancing the effect of shaking off the dust on the dust removal plate.

[0023] The present invention utilizes fluorescent powder to visually observe the gas discharged from the gas outlet pipe and the dust in the collection bucket, so as to timely discover the abnormality of the purifier, and to conduct problem investigation, repair and replacement.

DETAILED DESCRIPTION

[0042] The present invention will be further described below with reference to the accompanying drawings and examples.

[0043] Example 1: A waste gas purifier for chemical production, such as Figures 1 to 9As shown, it includes a purifier body 1, the upper left side of the purifier body 1 is connected to an air inlet pipe 11, the front right side of the purifier body 1 is fixedly connected to a transparent window 12 for observing the internal situation of the purifier body 1, the front left side of the purifier body 1 is rotatably connected to a rotating door for easy maintenance of the inside of the purifier body 1, the lower right side of the purifier body 1 is connected to an air outlet pipe 13, the right side of the purifier body 1 is fixedly connected to a mounting plate 14, the interior of the mounting plate 14 serves as a purification unit to purify the exhaust gas, and the upper side of the interior of the mounting plate 14 is fixedly connected to an activated carbon adsorption plate 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 side of the purifier body 1, the mounting shell 15 serves 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 the dust removal plate 1501, the dust removal plate 1501 is in the shape of an umbrella, 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 side 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 back of the collecting shell 17. A collecting rack 19 is fixedly connected to the mounting shell 15. The collecting rack 19 longitudinally penetrates the water absorption plate 1502. The collecting rack 19 is used to collect dust on the two dust removal plates 1501. The inner wall of the left side of the purifier body 1 The lower part is fixedly connected to a dust suction pump 110, the top side of the dust suction pump 110 is connected to the collection frame 19, the bottom side of the dust suction pump 110 is connected to the collection shell 17, and the side of the installation shell 15 close to the air intake pipe 11 is fixedly connected to a cavity frame 111, the air guide pipe 18 is connected to the cavity frame 111, and the cavity frame 111 and the air intake 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 intake 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 collection 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 oxide catalyst layer 1402 can effectively absorb organic matter and some inorganic matter in the exhaust gas. The oxide catalytic layer 1402 can catalytically oxidize harmful substances in the exhaust gas at a lower 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 the harmful substances in the exhaust gas, converting them into harmless substances. In this way, after the exhaust gas undergoes multiple composite purification treatments, the harmful substances therein can be greatly removed, thereby improving the purification efficiency and stability of the exhaust gas. The exhaust gas that has undergone pretreatment and purification treatment 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 is then 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 level, 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 collection process of the above-mentioned 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 guide pipe 18 through the filter holes of the collecting bucket 16 and enter the cavity frame 111 upward, and then flow back to the 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 the second time to improve the exhaust gas treatment effect.

[0047] like Figure 10 As shown, it also includes two mounting brackets 23, and the two mounting brackets 23 are respectively fixedly connected in the mounting shell 15. The bottom of the mounting bracket 23 is fixedly connected with a circumferentially distributed second pull rope 25, and the second pull ropes 25 distributed circumferentially on the same side are fixedly connected with a connecting bracket 21. The bottom of the connecting bracket 21 is fixedly connected with a circumferentially distributed first pull rope 22, and the first pull rope 22 is fixedly connected with a knocking block 2. The knocking block 2 contacts the adjacent dust removal plate 1501 and is used to shake off the dust on the dust removal plate 1501. Three guide plates 24 are fixedly connected to the connecting bracket 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 to slide into the collection rack 19, which affects the collection of dust. In order to assist the dust in sliding, 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 inside of the 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 connected to a magnetic plate 32 for sliding 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. The front side of the collecting bucket 16 is fixedly connected to a folding frame 33, 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 sealed. The specific operation is as follows: when the collecting bucket 16 is pulled forward, the collecting bucket 16 drives the folding frame 33 to move forward, thereby driving the folding 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 is stationary, and the side fixedly connected to the folding frame 33 moves forward with the folding 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 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 gathering frame 33 and the fixed plate 3 will move backward 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 does not move, and the side fixedly connected to the gathering frame 33 moves backward with the gathering frame 33, so that the cover cloth 34 is gradually folded and gathered, and the collecting bucket 16 is opened to collect dust.

[0052] Example 2: Based on Example 1, Figures 14 and 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 blade 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] Example 3: Based on Example 2, Figures 16 and 17 As shown, it also includes a storage tank 5 symmetrically distributed along the front and back of the cavity frame 111. The storage tank 5 can store fluorescent powder or other pigment powder. The storage tank 5 is connected to the cavity frame 111. 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. 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. Part of the exhaust gas entering the cavity frame 111 through the air guide pipe 18 will blow the impeller 52 to rotate, causing the grooves on the outer periphery of the impeller 52 to rotate intermittently to the bottom of the discharge block 51. The fluorescent powder in the storage tank 5 falls into the grooves of the impeller 52 through the air guide pipe 1503 and the discharge block 51 in turn. When the grooves of the impeller 52 rotate away from the discharge block 51, the fluorescent powder carried by the grooves 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 the problem needs to be checked and repaired in time.

[0056] Although the present disclosure has been shown and described with reference to certain exemplary embodiments thereof, it will 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-described embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
