Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, in particular to a waste gas purification box. Background Art

[0002] Waste gas is inevitably generated in the process of industrial production and fuel combustion. The waste gas contains solid particles, smoke, and toxic and harmful gases. Therefore, the waste gas must be treated before it is discharged. The waste gas treatment method is mostly spraying. Spraying the waste gas with liquid medicine can effectively reduce the content of solid particles, smoke, and toxic and harmful gases in the waste gas, thereby meeting the emission standards.

[0003] The existing activated carbon layer is usually set up in one layer, which makes the subsequent recovery and reuse process of the activated carbon cumbersome. The activated carbon needs to be taken out of the equipment for processing, and then needs to be refilled into the equipment after processing. The effective contact area between the exhaust gas and the activated carbon layer is low during the flow process, and the activated carbon in some areas cannot contact the exhaust gas. Summary of the invention

[0004] The object of the present invention is to provide an exhaust gas purification box to overcome the above-mentioned defects in the prior art.

[0005] According to an exhaust gas purification box of the present invention, it includes a box body, an open cavity opened up and down is provided in the box body, and fixed frames uniformly distributed on the left and right are fixed on the front and rear side walls of the open cavity, an activated carbon layer is provided in the fixed frame, and filters are connected to the left and right end surfaces of the fixed frame, and the filter abuts the left and right ends of the activated carbon layer, and guide slides symmetrically arranged on the left and right ends of the box body are provided on the left and right end surfaces of the box body, and sliding plates are fixed on the left and right end surfaces of the box body, and the sliding plates are slidably arranged in the guide slides, and fixed plates are provided on the upper and lower ends of the box body, and buckle grooves are provided on the fixed plates, and the ends close to each other of the two fixed plates are fixed with long plates and short plates distributed alternately, and the long plates and the short plates abut the filters on the left and right ends, and slots are provided between the upper and lower adjacent long plates and the short plates, and two left and right connecting boxes are provided on the upper and lower ends of the box body, and the two connecting boxes are connected with sliding ways, and the sliding ways are connected to the activated carbon layer in the box body, and two upper and lower connecting gas grooves distributed are respectively provided on the activated carbon layer at the leftmost end and the rightmost end.

[0006] Preferably, sliding grooves are provided at the front and rear ends of the connecting box, and sliding blocks are fixedly provided at the front and rear ends of the sliding channel to slidably cooperate with the sliding grooves, and the sliding grooves are arranged in a T-shape, and a guide sliding rod is fixedly provided in the sliding grooves, and the guide sliding rod slidably cooperates with the sliding block on the sliding channel, and a push spring is connected between the sliding block and the upper side wall of the sliding groove. The rear end surface of the box body has two rear openings arranged up and down and distributed left and right, and a clamping plate is fixedly provided on the fixing plate, and the clamping plate is clamped with the box body, and the clamping plate has elasticity, and a front opening is provided on the inner end surface of the rear end part of the fixing plate, and the angles between the front opening and the fixing plate and the rear opening and the box body surface are obtuse angles, and a heat absorption tube is inserted into the box body, and the heat absorption tube extends front and back and is arranged left and right at the heat absorption tube.

[0007] The beneficial effects of the present invention are:

[0008] By arranging the activated carbon layer in multiple sections at intervals, the thickness of a single activated carbon layer is reduced, thereby improving the heat absorption efficiency of the activated carbon layer and maintaining the temperature uniformity of the activated carbon layer, thereby speeding up the dehumidification and dust removal treatment of the activated carbon layer and facilitating the subsequent recycling and reuse of the activated carbon layer.

[0009] By setting the activated carbon layer in intervals and multiple sections, the flow distance of the exhaust gas is increased during the exhaust gas absorption process, thereby improving the absorption effect of impurities in the exhaust gas. By separating the long plates and the short plates, the exhaust gas can fully flow in the upper and lower parts of the activated carbon layer, thereby improving the utilization rate of the activated carbon layer and further improving the exhaust gas purification effect.

[0010] The sliding path provides support through spring force, and in contact with the front and rear ports, it realizes rapid disassembly and assembly, improves replacement efficiency, and absorbs heat in the exhaust gas through the liquid in the heat absorption tube, thereby reducing the temperature of the exhaust gas discharged through the lower end connecting air groove.

[0022] Embodiment 1:

[0023] Reference Figure 1-Figure 8According to an embodiment of the present invention, an exhaust gas purification box includes a box body 10, an open cavity 30 opened up and down is provided in the box body 10, and a fixed frame 18 evenly distributed on the left and right sides of the open cavity 30 is fixedly provided. An activated carbon layer 20 is provided in the fixed frame 18, and a filter screen 19 is connected to both left and right end surfaces of the fixed frame 18. The filter screen 19 abuts against both left and right ends of the activated carbon layer 20. Both left and right ends of the box body 10 are provided with a guide slide 23 symmetrical in upper and lower directions, and both left and right end surfaces of the box body 10 are fixedly provided with a sliding plate 24, and the sliding plate 24 is slidably arranged in the guide slide 23. Both upper and lower ends of the box body 10 are provided with A fixing plate 17, on which a buckle groove 25 is provided, and the two fixing plates 17 are fixed with staggered long plates 26 and short plates 27 at the ends close to each other, and the long plates 26 and short plates 27 abut against the filter screens 19 at the left and right ends, and a groove 22 is provided between the upper and lower adjacent long plates 26 and short plates 27, and two left and right connecting boxes 11 are provided at the upper and lower ends of the box body 10, and the two connecting boxes 11 are connected with a slideway 12, and the slideway 12 is connected to the activated carbon layer 20 in the box body 10, and two upper and lower connecting air grooves 28 are respectively provided on the activated carbon layer 20 at the leftmost end and the rightmost end;

[0024] The connection box 11 at the upper end is connected to the exhaust gas inlet pipe, and the connection box 11 at the lower end is connected to the exhaust pipe. The box body 10 is set on the left and right guide slides 23. The sliding plates 24 at the left and right ends of the box body 10 are inserted into the guide slides 23, and the sliding plates 24 are slidably matched at the guide slides 23, so that the box body 10 can slide back and forth between the two guide slides 23 until the box body 10 is installed. The front end of the guide slide 23 abuts against the rear end of the sliding plate 24. The slideway 12 is connected to the activated carbon layer 20 through two push springs 29, and the exhaust gas at the connection box 11 and the slideway 12 first enters the activated carbon layer 20 at the leftmost end from the upper end through the connecting air groove 28, and flows from top to bottom in the activated carbon layer 20. After being filtered by the activated carbon layer 20, the exhaust gas is discharged to the right through the filter screen 19. When the exhaust gas is blocked by the long plate 26 and the short plate 27, the exhaust gas in the activated carbon layer 20 at the leftmost end flows to the right side. The exhaust gas flows downward through the slot 22 provided and is discharged to the right, so that the exhaust gas entering the box body 10 flows up and down and left and right in the box body 10, and is finally discharged downward into the connection box 11 at the lower end through the connecting air slot 28 opened at the lower end, and is discharged outward through the exhaust pipe connected to the connection box 11 at the lower end. When disassembling and maintaining, the box body 10 is pulled forward so that the rear end part of the slide channel 12 abuts against the inclined surface at the front opening 15, and the slide channel 12 overcomes the force of the push spring 29 and shrinks into the connection box 11, so that the fixing plate 17 is partially disengaged from the abutment with the slide channel 12. The user removes the fixing plate 17 from the upper and lower ends of the box body 10 by removing the fixing plate 17 from the upper and lower ends of the box body 10. The user prevents the box body 10 from being heated in the heating device, removes the liquid absorbed in the activated carbon layer 20, and sets the box body 10 on the vibration device, and transmits the vibration force to the activated carbon layer 20, so that the dust adsorbed by the activated carbon layer 20 is discharged from the filter 19;

[0025] To disassemble and assemble the fixing plate 17 , the user can extract the fixing plate 17 by holding the buckle slot 25 and the opening at the other end of the fixing plate 17 . The filter screen 19 is used to prevent the activated carbon layer 20 from discharging dust.

[0026] Under the spring force of the push spring 29, the sliding channel 12 is provided with an activated carbon layer 20 evenly distributed on the left and right inside the box body 10. The activated carbon layer 20 absorbs impurities in the exhaust gas. The fixed plate 17 is installed at the upper and lower ends of the box body 10. The long plate 26 and the short plate 27 on the fixed plate 17 can separate the fixed frame 18 on the left and right.

[0029] Two fixing plates 17 are respectively inserted into the upper and lower ends of the box body 10. By pushing the fixing plates 17 with force, the card plates 31 on the fixing plates 17 are elastically deformed and clamped in the box body 10. The outer end surface of the fixing plates 17 abuts against the inner side wall of the cavity 30, and then the box body 10 is pushed backward, and the sliding channel 12 on the connecting box 11 abuts against the rear port 16 on the box body 10. Under the thrust of the inclined surface of the rear port 16, the sliding channel 12 overcomes the spring force at the push spring 29 and shrinks into the connecting box 11 until the installation of the box body 10 is completed. The sliding channel 12 moves downward and resets under the action of the spring force. A heat absorption pipe 21 is provided at the slot 22 of the exhaust gas flow path.
