Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a multi-stage waste gas treatment device. Background Technology

[0002] A multi-stage activated carbon waste gas adsorption box is a multi-stage device used to treat industrial waste gas. It mainly removes organic matter, odors, and some inorganic pollutants from waste gas through the adsorption of multi-stage activated carbon to meet emission standards. Its core working principle is based on the porous structure and strong adsorption properties of activated carbon, which can efficiently remove VOCs, odors, and some inorganic pollutants from waste gas.

[0003] Existing multi-stage activated carbon adsorption boxes mainly treat waste gas through internal activated carbon boxes. However, the service life of the activated carbon boxes varies depending on the state of the waste gas being treated, so the activated carbon boxes need to be replaced regularly. Existing equipment requires stopping the supply of waste gas before the activated carbon boxes can be replaced, which leads to equipment downtime and reduces its working efficiency.

[0004] Therefore, this utility model provides a multi-stage waste gas treatment device to solve the above problems. Utility Model Content

[0005] This invention provides a multi-stage waste gas treatment device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage waste gas treatment device, comprising an adsorption box, wherein a guide plate, a hollow plate, and a partition are fixedly connected to the inner wall of the adsorption box, and the guide plate and the partition are respectively located at both ends of the hollow plate. A permeable plate is provided at both the upper and lower ends of the hollow plate, and two sets of activated carbon boxes are provided between the two hollow plates; an inspection cover, which is fitted over the inspection window of the adsorption box; and a sealing assembly, comprising a sealing cover, which is fixedly connected to the rear side of the adsorption box, and a screw is threadedly connected to the inside of the sealing cover. One end of the screw is rotatably connected to an adjusting plate, and the other end of the adjusting plate is fixedly connected to two sealing plates, which are inserted into the interior of the hollow plate.

[0007] As a preferred technical solution of this application, a handle is fixedly connected to the outer wall of the inspection cover, and an extrusion plate is placed above the handle. Both ends of the extrusion plate are provided with hinge frames, and the hinge frames are rotatably connected to the outer wall of the adsorption box.

[0008] As a preferred technical solution of this application, a hand-tightening bolt is threaded at the center of the hinge frame, and the hand-tightening bolt abuts against the outer wall of the extrusion plate. The outer wall of the adsorption box is provided with a baffle for vertically limiting the hand-tightening bolt.

[0009] As a preferred technical solution of this application, the guide plate is provided with two upper and lower parts, and a total of four hollow plates are provided, with the two hollow plates in the middle located at the ends of the two guide plates that are close to each other.

[0010] As a preferred technical solution of this application, a total of four screws are provided, and each screw corresponds to an adjustment plate. The connection end between the screw and the adjustment plate is I-shaped, and the other end of the screw is fixedly connected to an anti-slip handle.

[0011] As a preferred technical solution of this application, each set of activated carbon boxes has a sealing plate at both the upper and lower ends. Both the sealing plate and the ventilating plate are provided with ventilating holes, and the spacing between the ventilating holes is not less than the diameter of the ventilating holes. The outer wall of the sealing plate is wrapped with a sealing gasket.

[0012] The beneficial effects of this application are as follows:

[0013] This invention, through the setting of a sealing component, can seal each group of activated carbon boxes separately, thereby enabling the device to replace activated carbon boxes without shutting down the machine. This improves the continuity of the device's operation and greatly increases its working efficiency. The sealing component also prevents the leakage of waste gas during the replacement of activated carbon boxes, thus not only improving the continuity of equipment operation but also ensuring the safety of activated carbon box replacement.

[0014] This utility model, through the arrangement of an inspection cover, a positioning plate, a hinge frame, and bolts, enables the positioning plate to seal the inspection cover under the pressure of the bolts, thereby achieving a sealed installation of the cover. At the same time, the hinge frame can be rotated when the bolts are loosened, thereby releasing the pressure on the positioning plate and allowing the inspection cover to be opened. This makes disassembly and assembly more convenient and facilitates the replacement and maintenance of the activated carbon box. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 As shown, this utility model provides a multi-stage waste gas treatment device, including an adsorption box 1. A guide plate 11, a hollow plate 12, and a partition plate 13 are fixedly connected to the inner wall of the adsorption box 1. The guide plate 11 and the partition plate 13 are respectively located at both ends of the hollow plate 12. Ventilation plates 14 are provided at both the upper and lower ends of the hollow plate 12. Two sets of activated carbon boxes 5 are provided between the two hollow plates 12. An inspection cover 2 is fitted over the inspection window of the adsorption box 1. A sealing assembly 4 includes a sealing cover 41, which is fixedly connected to the rear side of the adsorption box 1. A screw 42 is threadedly connected to the inside of the sealing cover 41. One end of the screw 42 is rotatably connected to an adjusting plate 43, and the other end of the adjusting plate 43 is fixedly connected to two… A sealing plate 44 is inserted into the hollow plate 12. The rotation of the screw 42 drives the adjustment plate 43 to adjust its displacement. The movement of the adjustment plate 43 can then pull and adjust the sealing plate 44. When the sealing plate 44 and the air vent of the air vent 14 are aligned, gas can pass through. Conversely, when the sealing plate 44 and the air vent of the air vent 14 are misaligned, the activated carbon box 5 at the corresponding position can be sealed and wrapped. The activated carbon box 5 at that position can be disassembled and replaced without shutting down the adsorption box 1. This ensures that the activated carbon boxes 5 at other positions in the adsorption box 1 can still be purified, thus achieving non-stop maintenance of the device and greatly improving the continuity of the device's use.

[0024] Furthermore, a handle 21 is fixedly connected to the outer wall of the inspection cover 2, and a pressing plate 3 is placed above the handle 21. Both ends of the pressing plate 3 are provided with hinge frames 31, and the hinge frames 31 are rotatably connected to the outer wall of the adsorption box 1. A hand-tightening bolt 32 is threadedly connected to the center of the hinge frame 31, and the hand-tightening bolt 32 abuts against the outer wall of the pressing plate 3. The outer wall of the adsorption box 1 is provided with a baffle for vertically limiting the hand-tightening bolt 32. By rotating the hinge frame 31, the hand-tightening bolt 32 is perpendicularly distributed with the pressing plate 3, and then the hand-tightening bolt 32 is rotated, so that the hand-tightening bolt 32 presses against the pressing plate 3. The pressing of the inspection cover 2 by the pressing plate 3 completes the sealing treatment of the inspection window of the adsorption box 1. This pressing disassembly and assembly is more convenient than the bolt positioning disassembly and assembly, thus facilitating the later maintenance of the activated carbon box 5.

[0025] Furthermore, there are two guide plates 11, one at the top and one at the bottom, and four hollow plates 12 in total. The two hollow plates 12 in the middle are located at the ends of the two guide plates 11 that are close to each other. The exhaust gas enters between the hollow plates 12 through the center of the two guide plates 11 and is further guided upward and downward, so that the exhaust gas is separated and purified by contact with the activated carbon box 5 before being discharged.

[0026] Furthermore, there are four screws 42 in total, and each screw 42 corresponds to an adjusting plate 43. The connection end between the screw 42 and the adjusting plate 43 is in the shape of an I-beam. The other end of the screw 42 is fixedly connected to an anti-slip handle. The anti-slip handle facilitates the rotation drive of the screw 42. At the same time, the rotational connection between the screw 42 and the adjusting plate 43 ensures that the rotational displacement of the screw 42 can only achieve the pulling displacement of the adjusting plate 43, so that the sealing plate 44 and the vent plate 14 maintain good sliding limit.

[0027] Furthermore, each set of activated carbon boxes 5 has a sealing plate 44 at both the top and bottom. Both the sealing plate 44 and the vent plate 14 have vent holes, and the spacing between the vent holes is not less than the diameter of the vent holes. The outer wall of the sealing plate 44 is wrapped with a sealing gasket. The setting of the sealing gasket ensures the sealing performance of the sealing plate 44 and the vent plate 14. At the same time, the spacing between the vent holes is greater than the diameter of the vent holes, ensuring that the sealing plate 44 can meet the misalignment and sealing of the vent holes when it slides.

[0028] Working principle: First, the device is installed. After a certain period of use, a screw 42 is rotated, which in turn moves the adjusting plate 43, thereby controlling the tension of the sealing plate 44. When the air holes of the sealing plate 44 and the vent plate 14 are misaligned, the activated carbon box 5 is sealed. At this point, the pressing plate 3 at the corresponding position is disassembled, and the inspection cover 2 can be removed. Finally, the activated carbon box 5 can be disassembled and replaced without shutting down the exhaust gas purification system.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
