Description

Technical Field

[0001] The invention relates to the technical field of impurity adsorption and separation, in particular to a VOCS condensation adsorption device. Background Art

[0002] VOCs (volatile organic compounds) refer to organic compounds that are volatile at room temperature. They come from waste gases in various industrial processes and daily activities. These VOCs are harmful to the environment and human health, so they need to be recycled and processed. Common VOCs treatment methods generally use adsorbent adsorption and condensation to achieve treatment.

[0003] The existing Chinese patent application with publication number CN112403196A discloses a VOCs waste gas treatment purifier, including a reaction tank, a rotating plate and a partition; a partition is fixedly connected to the middle of the reaction tank, and the partition divides the reaction tank into a left chamber and a right chamber that are not connected to each other; a condensing device is arranged inside the upper end of the right chamber; a rotating ring is rotatably connected to the outer surface of the reaction tank, and a uniformly arranged first magnet block is fixedly connected inside the rotating ring; a rotating plate is rotatably connected inside the reaction tank; a second magnet block is connected inside the rotating plate relative to one end of the rotating plate, and the first magnet block and the second magnet block are designed in a one-to-one correspondence; a graphite layer and an activated carbon layer are arranged inside the rotating plate; a collecting bin is fixedly connected to the outer surface of the lower end of the reaction tank; an exhaust pipe is fixedly connected to the upper end of the left side wall of the reaction tank; the invention, through the rotation of the rotating plate, gas adsorption and desorption are carried out, so as to obtain pure VOCs gas, improve the utilization rate of VOCs gas, and avoid frequent replacement of adsorbents.

[0004] However, the condensation adsorption device has the following defects when used:

[0005] 1. When existing condensation adsorption devices separate VOCs (volatile organic compounds) impurities in exhaust gas, they generally use adsorbents to adsorb VOCs (volatile organic compounds) impurities in exhaust gas to achieve the separation operation. At this time, it is difficult to reuse the adsorbent that adsorbs VOCs (volatile organic compounds) impurities, and the loss of the adsorbent is relatively large. At the same time, other metal particle impurities in the exhaust gas will also adhere to the surface of the adsorbent. On the one hand, it is inconvenient to subsequently recover these metal particle impurities. On the other hand, the weight of the adsorbent will increase sharply, affecting the reuse of the adsorbent.

[0006] 2. When existing condensation adsorption devices treat VOCs (volatile organic compounds) impurities in exhaust gas, they generally use condensation to condense VOCs in a gaseous state and separate them from the mixed exhaust gas to achieve VOCs (volatile organic compounds) separation operation. However, in actual operation, the traditional solution requires a lot of time to condense VOCs (volatile organic compounds), and the efficiency of VOCs (volatile organic compounds) separation operation is low.
