The lower end of the rotating part penetrates through the shell and is located in the base to be connected with a linkage part. According to the rotary drum type zeolite concentration device structure for concentration of low-concentration VOCs, the linkage component not only ensures stable transmission of power, but also converts high-speed power into low-speed power suitable for rotation of the rotating component through the built-in speed reducing mechanism. And the rotating part decelerates again, so that the power output is milder and more stable, and the zeolite rotating drum is driven to rotate at a proper speed. The rotation action not only maintains the adsorption efficiency of the zeolite rotary drum, but also realizes the reutilization of energy released in the combustion process of the concentrated VOCs gas.

Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, in particular to a rotary drum type zeolite concentration device structure for concentrating low-concentration VOCs. Background Art

[0002] VOCs, short for Volatile Organic Compounds, are a class of organic compounds that evaporate readily at room temperature and pressure. These compounds typically have low boiling points, allowing them to exist as gases in the environment. There are many types of VOCs, including but not limited to hydrocarbons, alcohols, aldehydes, ketones, esters, and amines.

[0003] When treating exhaust gases containing volatile organic compounds (VOCs), the use of purification equipment is crucial. Zeolite drums, as highly efficient adsorption devices, are often used in this process. These devices utilize the porous structure of zeolite to effectively adsorb VOCs from exhaust gases, thereby purifying the air.

[0004] However, existing zeolite drum systems have limitations in their VOC desorption process. Typically, desorbed VOCs are transferred to a dedicated container for combustion. While this process removes harmful organic compounds, it also consumes energy that could otherwise be recycled, making it inefficient in terms of energy efficiency.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original rotary drum type zeolite concentration device. Utility Model Content

[0008] Preferably, the rotating component includes a gear disc, a first full gear, and a vertical shaft. The bottom of the shell is rotatably connected to the gear disc, and a zeolite drum is installed on the top of the gear disc. The side of the gear disc is meshed with the first full gear, and the first full gear is connected to the vertical shaft, and the lower end of the vertical shaft passes through the bottom of the shell and is connected to a linkage component.

[0009] Preferably, the diameter of the toothed disc is larger than the diameter of the first full gear.

[0010] Preferably, the linkage component includes a first bevel gear set, a horizontal shaft, a second bevel gear set, a connecting shaft, a full gear set, an auxiliary shaft, and a chain. The lower end of the vertical shaft is connected to the first bevel gear set, and the first bevel gear set is connected to the horizontal shaft. One end of the horizontal shaft is rotatably connected to the inner wall of one end of the base, and the other end of the horizontal shaft is connected to the second bevel gear set. The second bevel gear set is connected to the connecting shaft, and the two ends of the connecting shaft are respectively connected to the inner walls on both sides of the base, and the outer wall of the connecting shaft is connected to the full gear set. The full gear set is connected to the auxiliary shaft, and the end of the auxiliary shaft passes through the outer wall of the base and is connected to the chain through a sprocket, and the chain is connected to the Stirling machine through the sprocket.

[0011] Preferably, the diameter of the bevel gear on the horizontal axis of the first bevel gear set is larger than the diameter of the bevel gear on the vertical axis, the diameter of the bevel gear on the second bevel gear set is larger than the diameter of the bevel gear on the horizontal axis, and the diameter of the full gear on the connecting shaft of the full gear set is larger than the diameter of the full gear on the auxiliary shaft.

[0012] Preferably, the combustion component includes a box body, a guide block, an igniter, and an open partition. The top of the base is connected to the box body, and the bottom of the box body is connected to the guide block, and the guide block is provided with an igniter. The box body is connected to an open partition, and the opening on the open partition is located above the igniter, and the end of the Stirling engine cylinder is located above the opening of the open partition.

[0013] Compared to existing technologies, the present invention offers the following advantages: This rotary drum zeolite concentrator for low-concentration VOCs concentration utilizes a rotating component, linkage components, a Stirling engine, and combustion components. The zeolite drum, through its fine pore structure, effectively adsorbs volatile organic compounds (VOCs) from exhaust gas. After these VOCs are released and concentrated during thermal desorption, they are directed into a specialized combustion chamber, where an igniter ignites the organic gases.

[0014] As VOCs burn, the heat generated by the combustion process is absorbed by the cylinder end of the Stirling engine, which converts it into mechanical energy, setting the engine in motion. The Stirling engine's design cleverly utilizes the principles of thermal expansion and cold compression of gases, converting heat directly into power. This power is transmitted to the linked components via a chain.

[0015] The linkage not only ensures smooth power transmission but also, through a built-in reduction mechanism, converts high-speed power into a low-speed power suitable for the rotating components. The rotating components then further reduce speed, resulting in a gentler and more stable power output, which in turn drives the zeolite drum to rotate at an appropriate speed. This rotational action not only maintains the zeolite drum's adsorption efficiency but also recycles the energy released during the combustion of concentrated VOCs. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Working principle: According to Figure 1As shown, first, the exhaust gas containing VOCs is transported into the shell 2.

The vertical shaft 403 drives the toothed disc 401 and the toothed disc 401 to rotate through the first full gear 402, so that the zeolite drum 3 rotates to adsorb the VOCs in the exhaust gas.

In addition, the air after combustion in the box 701 enters the zeolite drum 3 through the box 701, and is used to desorb the zeolite drum 3, and the cycle is repeated. This is the working principle of the drum-type zeolite concentration device structure for concentrating low-concentration VOCs.
