Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to an industrial waste gas purification device. Background Art

[0002] Industrial waste gas purification mainly aims at treating waste gas generated in industrial sites, such as dust particles, flue gas and soot, odor gas, and toxic and harmful gases. In industrial applications, activated carbon waste gas treatment equipment can adsorb various different gases, and is especially suitable for places with malodorous smells such as garbage recycling stations, farms, slaughterhouses, and spraying workshops.

[0003] The adsorption capacity of activated carbon is not infinite. As time goes by and the adsorbed substances increase, its adsorption capacity will gradually decline. Therefore, it needs to be replaced regularly to extend its service life. However, in the process of replacing activated carbon in the existing activated carbon purification device, it usually requires shutdown operation, thus interrupting the waste gas purification process and affecting the purification efficiency of waste gas. Therefore, in order to solve the foregoing problems, we propose an industrial waste gas purification device. Summary of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention;

[0023] Referring to Figures 1-5 , an industrial waste gas purification device includes a box body 1. An air inlet 3 and an air outlet 4 are respectively fixedly installed on the left and right sides of the box body 1. A first baffle 5 and a second baffle 6 are respectively fixedly installed on the left and right sides inside the box body 1. A supporting mesh plate 7 is fixedly installed between the first baffle 5 and the second baffle 6. Two air inlet slots 19 are opened inside the first baffle 5. Air outlet slots 18 are opened on the upper and lower sides inside the second baffle 6. The two air inlet slots 19 are located between the two supporting mesh plates 7. A plurality of activated carbon placement boxes 11 are placed on the tops of the two supporting mesh plates 7;

[0024] Activated carbon for purifying waste gas can be placed inside the activated carbon placement box 11, and a plurality of through holes are opened at the bottom of the activated carbon placement box 11;

[0025] Industrial waste gas to be purified can enter the inside of the box body 1 through the air inlet 3, pass through the first baffle 5 through the air inlet slot 19. The waste gas will pass through the supporting mesh plate 7 and contact the activated carbon. The activated carbon can purify the waste gas, and the purified gas will be discharged through the air outlet slot 18 and the air outlet 4.

[0026] Two access openings are opened on the front surface of the box body 1. A detachable plugging plate 2 is fixedly installed on the front surfaces of the two access openings. The two access openings are respectively located on the front sides of the tops of the two supporting mesh plates 7;

[0027] When it is necessary to replace the activated carbon in the activated carbon placement box 11, the plugging plate 2 can be detached, the access opening can be opened, and the activated carbon placement box 11 can be taken out from the inside of the box body 1.

[0028] A partition chamber 8 is provided inside the box body 1. The partition chamber 8 is located between two supporting mesh plates 7. A movable plate 2 17 for closing the air inlet slot 19 is rotatably installed on the left side of the partition chamber 8. Two movable plates 1 12 for closing the air outlet slot 18 are slidably installed on the right side inside the box body 1. A driving mechanism is fixedly installed inside the partition chamber 8. The driving mechanism is in transmission connection with the movable plate 2 17 and the two movable plates 1 12. The movable plate 2 17 is semicircular and the center of the circle is located between the two air inlet slots 19. The spacing between the two movable plates 1 12 is smaller than the spacing between the two air outlet slots 18. A rack 13 is fixedly installed between the two movable plates 1 12. Two sliding rods 20 are fixedly installed between the top and the bottom of the right side inside the box body 1. The two movable plates 1 12 are slidably connected with the two sliding rods 20. The driving mechanism includes a gearbox 1 9, a gearbox 2 15, a motor 16, and a rotating shaft 10. The gearbox 1 9 is fixedly installed on the left side of the partition chamber 8 and is in transmission connection with the movable plate 2 17. The gearbox 2 15 is fixedly installed on the right side of the partition chamber 8. The output end of one side of the gearbox 2 15 extends to the right side of the baffle 2 6 and is fixedly installed with a driving gear 14. The driving gear 14 is meshed and connected with the rack 13. The motor 16 is fixedly installed on the front side of the gearbox 1 9 and is in transmission connection with the gearbox 1 9. The rotating shaft 10 is transmission-installed between the gearbox 1 9 and the gearbox 2 15.

[0029] The movable plate 12 and the movable plate 2 17 can seal the air outlet slot 18 and the air inlet slot 19 to prevent industrial waste gas from passing through;

[0030] The movable plate 2 17 can only close one air inlet slot 19. Since the distance between the two movable plates 12 is smaller than the distance between the two air outlet slots 18, the two movable plates 12 can only close one air outlet slot 18 at the same time.

[0031] When the movable plate 2 17 and the movable plate 1 12 simultaneously close the lower air inlet slot 19 and the air outlet slot 18, the industrial waste gas can only pass through the upper air inlet slot 19 and be discharged through the upper air outlet slot 18. At this time, only the activated carbon located inside the box 1 is used for waste gas purification.

[0032] When the activated carbon inside the box body 1 needs to be replaced, the motor 16 can be started to drive the movable plate 2 17 to rotate through the gear box 1 9, the rotating shaft 10, and the gear box 2 15, and the two movable plates 12 move upward, so that the movable plate 2 17 closes the upper air inlet slot 19, and the movable plate 12 closes the upper air outlet slot 18. The air inlet slot 19 and the air outlet slot 18 at the lower part of the box body 1 are opened, and the industrial waste gas can pass through and be purified from the lower part of the box body 1. Therefore, the device can still pass through and purify the industrial waste gas during the process of replacing the activated carbon.
