Description

Technical Field

[0001] This utility model relates to the field of waste gas purification technology, and in particular to an industrial waste gas purification device. Background Technology

[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory area. If these waste gases are discharged directly without purification, they will cause serious harm to the environment and human health. Therefore, industrial waste gas needs to be purified before it is discharged.

[0003] Publication number CN210145821U discloses an industrial automated waste gas purification device, including a purification cylinder. An inlet pipe is fixedly connected to the lower end of the purification cylinder, and an outlet pipe is fixedly connected to the upper end. A liquid storage tank is fixedly connected to the outer end of the purification cylinder. A conduit with a valve is fixedly connected between the lower end of the liquid storage tank and the purification cylinder. An air-permeable mesh is provided inside the purification cylinder, and a limit rod is fixedly connected to the right end of the mesh. A circular groove is carved into the inner wall of the purification cylinder, and the limit rod is rotatably connected to the circular groove. A fixing plate is fixedly connected to the left end of the purification cylinder, and an inner groove and an outer groove are carved on the fixing plate, with the inner groove located to the right of the outer groove. This purification device can control the flow rate of waste gas within the purification cylinder by rotating the air-permeable mesh, thereby controlling the residence time of the waste gas within the purification cylinder, allowing the waste gas to react more thoroughly within the purification cylinder, and improving its purification effect.

[0004] The above-mentioned purification device has the following defects: when the air mesh rotates, it will create a gap with the inner wall of the purification cylinder, and the exhaust gas will pass directly through the gap, affecting the purification effect. This method of controlling the residence time of exhaust gas in the purification cylinder is not effective in actual use.

[0005] Therefore, an industrial waste gas purification device is proposed. Utility Model Content

[0029] Reference Figures 1-6 This invention provides an industrial waste gas purification device, which includes a purification tank 1. Four sets of support rods 17 for supporting the purification tank 1 are fixedly connected to the bottom of the purification tank 1. The side wall of the purification tank 1 is connected to an exhaust pipe 4, an air inlet pipe 2 and a drain pipe 3 from top to bottom. The exhaust pipe 4 and the air inlet pipe 2 are not at the same height, which can increase the exhaust distance of the waste gas, thereby improving the waste gas purification effect. The exhaust pipe 4 and the air inlet pipe 2 are centrally symmetrically distributed with a certain point on the axis of the purification tank 1 as the center.

[0030] Inside the purification tank 1, below the drain pipe 3, there is a sealed rotating lower turntable 5 with a rotating shaft at the bottom. The rotating shaft of the lower turntable 5 rotates through the purification tank 1. The bottom end of the rotating shaft of the lower turntable 5 is fixedly connected to a worm gear 11. A worm 12 is rotatably arranged below the purification tank 1. The worm 12 meshes with the worm gear 11. The turntable 5 can be rotated by rotating the worm 12.

[0031] The purification tank 1 is connected to the upper turntable 6 in a sealed rotatable manner above the exhaust pipe 4. This sealed rotatable connection can be achieved by setting an O-ring at the connection between the upper turntable 6 and the purification tank 1. The lower turntable 5 and the upper turntable 6 are fixedly connected to multiple sets of guide plates 7 for guiding the exhaust gas. The multiple sets of guide plates 7 are staggered and parallel to each other. The multiple sets of guide plates 7 cooperate with the purification tank 1 to form a serpentine channel inside the purification tank 1.

[0032] Multiple sets of spray nozzles 9, which spray adsorbent to purify exhaust gas, are fixedly installed on the upper turntable 6. These nozzles 9 are evenly distributed. Exhaust gas enters the device through the inlet pipe 2, and the multiple spray nozzles 9 spray adsorbent to purify the exhaust gas. When the multiple guide plates 7 are perpendicular to the inlet pipe 2, such as... Figure 4 As shown, the exhaust gas needs to pass through the serpentine channel formed by multiple sets of guide plates 7 and the purification tank 1 before it can be discharged from the exhaust pipe 4 to the next process. In this state, the exhaust gas stays in the purification tank 1 for the longest time, which can improve the exhaust gas purification effect when the exhaust gas concentration is high. When the multiple sets of guide plates 7 are parallel to the air inlet pipe 2, such as Figure 5 As shown, at this time, the exhaust gas can be directly discharged to the exhaust pipe 4 through the gaps between the multiple sets of guide plates 7. In this state, the exhaust gas can quickly pass through the purification tank 1, and the exhaust gas can be treated at the fastest speed when the exhaust gas concentration is low. By rotating the worm gear 12, the lower turntable 5 can be rotated through the worm wheel 11. The rotation of the lower turntable 5 can synchronously rotate the multiple sets of guide plates 7, thereby adjusting the relative position of the intake pipe 2 and the exhaust pipe 4 with respect to the serpentine channel.

[0033] like Figure 2 As shown, a limiting rod 15 is fixedly connected to the shaft of the lower turntable 5 between the worm gear 11 and the purification tank 1. The limiting rod 15 is set parallel to the guide plate 7. Two sets of limiting posts 16 are also fixedly connected to the bottom of the purification tank 1. When the limiting rod 15 abuts against the two sets of limiting posts 16 respectively, the guide plate 7 is parallel and perpendicular to the axis of the air inlet pipe 2 respectively. By setting the limiting rod 15 and the two sets of limiting posts 16 together, the operator can easily judge the status of the multiple sets of guide plates 7.

[0034] like Figure 3 As shown, a water tank 8 is fixedly connected to the top of the upper turntable 6, and multiple sets of spray heads 9 are fixedly connected to the water tank 8. An inlet pipe 10 is fixedly installed on the top of the purification tank 1. The water tank 8 and the inlet pipe 10 are connected in a sealed rotational manner. When in use, the adsorbent is introduced into the water tank 8 through the inlet pipe 10, and the adsorbent will be sprayed out through the multiple sets of spray heads 9 connected to the water tank 8 to purify the exhaust gas.

[0035] like Figure 2 As shown, two sets of bearing seats 13 are fixedly connected to the bottom of the purification tank 1. The worm gear 12 is rotatably connected to the two sets of bearing seats 13 and passes through the two sets of bearing seats 13. The worm gear 12 is rotatably set below the purification tank 1 through the two sets of bearing seats 13. A handwheel 14 is also fixedly connected to one end of the worm gear 12 shaft. The handwheel 14 is set to coincide with the axis of the worm gear 12. The handwheel is used to facilitate the rotation of the worm gear 12.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
