Description

Technical Field

[0001] The utility model relates to the field of industrial waste gas treatment, and more specifically, to industrial waste gas adsorption and desorption equipment. Background Art

[0002] Industrial waste gas refers to various pollutant-containing gases emitted during industrial production. It primarily originates from the energy and raw material processing sectors, the chemical industry, and manufacturing. It contains pollutants such as sulfur oxides, carbon oxides, and particulate matter. These gases must be treated to meet emission standards. A common device for treating waste gas in existing technologies is the zeolite rotor, which primarily consists of an adsorption zone, a desorption zone, and a cooling zone. Exhaust gas is introduced into the zeolite rotor's adsorption zone via a fan. Zeolite, with its unique molecular structure and strong adsorption capacity, effectively absorbs volatile organic compounds (VOCs) from the waste gas. When the adsorption is saturated, the zeolite wheel slowly rotates into the desorption zone, wherein the pretreatment of the particulate matter in the exhaust gas is mostly carried out by blocking the particulate matter through a filter or filter cloth, etc., for preliminary treatment to filter out larger particulate matter, and then passing it into the zeolite wheel equipment. During the pretreatment, the particulate matter adheres to the surface of the filter, which makes the filter holes on the surface of the filter become clogged after long-term use, thereby affecting the flow of exhaust gas. Therefore, the filter needs to be cleaned regularly. In the existing technology, when cleaning the filter, it is often necessary to shut down the machine to remove or replace the filter, which is always extremely inconvenient. Utility Model Content

Specific implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment:

[0023] Please refer to Figures 1 - 3 As shown, an industrial waste gas adsorption and desorption device includes a zeolite wheel 20 and a housing installed at the air inlet end of the zeolite wheel 20. The zeolite of the zeolite wheel 20 mainly consists of an adsorption area, a desorption area, and a cooling area. The waste gas is introduced into the adsorption area of the zeolite wheel 20 through a fan. The zeolite has a unique molecular structure and strong adsorption capacity, and can effectively adsorb volatile organic compounds (VOCs) in the waste gas. When the adsorption is saturated, the zeolite wheel slowly rotates into the desorption area. In the desorption area, the VOCs adsorbed on the zeolite are desorbed by high-temperature hot air to form high-concentration waste gas. When introducing the waste gas into the zeolite wheel 20, it will first pass through the housing 1 for pretreatment to achieve preliminary filtration.

[0024] Among them, an air inlet pipe 2 is provided at one end of the housing 1, and an air outlet pipe 3 is provided at the other end of the housing 1. Both the air inlet pipe 2 and the air outlet pipe 3 communicate with the inside of the housing 1, so that the waste gas can flow through the device to achieve the preliminary treatment of the waste gas. Connecting flanges 4 are provided on the sides of the air inlet pipe 2 and the air outlet pipe 3 facing away from each other to facilitate the connection of the device to the zeolite wheel device. An isolation plate 8 is provided inside the housing 1, and an adsorption net 801 is provided on the surface of the isolation plate 8. The adsorption net 801 is oval. The so-called oval is composed of two non-overlapping circular structures. An incomplete gear 9 is rotatably installed symmetrically about the center of the surface of the adsorption net 801. The incomplete gear 9 coincides with the centers of the two long axes of the oval adsorption net 801. A swing plate 10 is provided on the surface of the incomplete gear 9, and a cleaning brush 11 is provided on one side surface of the swing plate 10. The cleaning brush 11 is in contact with the surface of the adsorption net 801. When the incomplete gear 9 rotates, it can drive the cleaning brush 11 to move relative to the surface of the adsorption net 801, thereby realizing the cleaning work. A sliding rod 12 is vertically slidably installed above the inside of the housing 1. A bidirectional rack 15 is provided at the bottom of the sliding rod 12. The bidirectional rack 15 is placed between the two incomplete gears 9, and the bidirectional rack 15 meshes with the two incomplete gears 9 respectively, so as to drive the two incomplete gears 9 to rotate synchronously and in opposite directions through the bidirectional rack 15.

[0025] Among them, the cross-sectional dimension of the bidirectional rack 15 is larger than that of the sliding rod 12. A spring 14 is sleeved on the surface of the sliding rod 12. The top of the spring 14 is in contact with the upper surface inside the housing 1, and the bottom of the spring 14 is in contact with the upper surface of the bidirectional rack 15. The elastic force of the spring 14 is used to make the bidirectional rack 15 always at the bottom of the stroke, and then drive the two swing plates 10 to move vertically upward, so that when the bidirectional rack 15 moves upward, the two swing plates 10 can rotate outward and downward to clean the dust particles adsorbed on the surface of the adsorption net 801 from top to bottom.

[0026] Please refer to Figure 1 and Figure 2 As shown, the sliding rod 12 penetrates through the upper surface of the housing 1, and a pulling plate 13 is provided at the top of the sliding rod 12 to facilitate the control of the sliding rod 12 from the outside to drive the bidirectional rack 15 to move.

[0027] Please refer to Figure 2 and Figure 4 As shown, a dust collection box 5 is provided at the bottom of the housing 1. The dust collection box 5 communicates with the inside of the housing 1. The dust collection box 5 is placed below one side of the isolation plate 8 close to the air inlet pipe 2. The dust collection box 5 has a conical structure with a large top and a small bottom to collect the scraped dust particles.

[0028] Among them, a dust outlet hole 6 is opened at the bottom of the isolation plate 8, and a plug 7 is inserted and pulled at the bottom of the dust outlet hole 6, so that the dust collection box 5 can be cleaned without shutting down the machine.

[0029] Working principle: The device is installed in the industrial waste gas pipeline through the connecting flange 4, and it is ensured that the gas flows in through the intake pipe 2 and out through the outlet pipe 3. At this time, the waste gas will pass through the adsorption net 801, and the dust particles in the waste gas will be filtered. At this time, the dust particles in the waste gas will adhere to the surface of the adsorption net 801 on the side close to the intake pipe 2. At the same time, due to the existence of the spring 14, the double-sided toothed rod 15 always has a downward force and is placed at the lowest position when not affected by external forces, so as to keep the cleaning brush 11 vertically upward through the cooperation of the two double-sided toothed rods 15 and the incomplete gear 9. When cleaning is required, the lifting plate 13 can be pulled up to drive the spring 14 to move upward, and then the two incomplete gears 9 will rotate, and the rotation directions are opposite, so that the swing plate 10 rotates, and the particles attached to the surface of the adsorption net 801 are cleaned from top to bottom by the cleaning brush 11. The cleaned dust will fall into the dust collection box 5 for centralized treatment and can be discharged through the dust outlet hole 6.

[0030] The above is only a preferred specific implementation manner of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitutions or changes,

[0031] should be covered within the protection scope of the present utility model.
