Description

Technical Field

[0001] This utility model relates to the field of rotary adsorption technology, and more specifically, to a sealing structure for a rotary adsorption bed. Background Technology

[0002] The treatment of volatile organic compounds (VOCs) has been a focus of attention for governments, enterprises, and the public in recent years. VOCs have a wide range of sources, covering multiple industries such as fine chemicals, electronics manufacturing, petroleum refining, industrial coating, and packaging printing. They are diverse in type and characteristics, which poses challenges to their treatment. my country has put forward higher requirements for the prevention and control of VOCs.

[0003] Guided by the national "dual carbon" policy and the circular economy, waste gas adsorption and recovery technology is gaining increasing popularity. Adsorption and recovery technology is a greener solvent recovery technology. Nitrogen-based adsorption-desorption recovery technology has been widely used in the market due to its advantages such as not producing wastewater or secondary pollution, low water content in the recovered solvent, higher quality of the recovered solvent, and wider range of applications.

[0004] With the rapid development of my country's economy, VOCs are involved in more and more polluting industries. At present, one of the mainstream technologies for industrial VOCs treatment is granular carbon adsorption and desorption technology. The principle of granular carbon adsorption for treating organic waste gas is mainly to use the adsorption performance of granular carbon to adsorb organic pollutants in the waste gas onto the surface of the granular carbon, thereby achieving the purpose of purifying the waste gas. Then, the high-temperature desorption performance of granular carbon is used to remove pollutants from the surface of the granular carbon at high temperature.

[0005] In conventional rotary adsorption beds, during long-term adsorption use, the rotor core and the fan-shaped sealing cavity will continuously rub against each other, causing gaps to form. This will prevent the different zones from sealing each other, allowing exhaust gas to seep through the gaps and thus failing to achieve the desired design.

[0006] Therefore, how to provide a practical and effective sealing device has become a technical problem that urgently needs to be solved in this field. Utility Model Content

The threaded lifting mechanism 4 includes a first threaded rod 41, a second threaded rod 42, and a third threaded rod 43. On one side of the rotating core 1, the first threaded rod 41 is arranged along the axial direction of the rotating core 1.

On the other side of the rotor core 1, a first threaded rod 41 is arranged along the axial direction of the rotor core 1. One end of the first threaded rod 41 is connected to the sector-shaped sealing cavity 2 to drive the sector-shaped sealing cavity 2 to move toward or away from the rotor core 1.
