Description

Technical Field

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

[0002] VOCs (volatile organic compounds) refer to organic compounds that are volatile at room temperature, and they come from waste gases in various industrial processes and daily activities. These VOCs are harmful to the environment and human health to a certain extent, so they need to be recovered and treated. Common VOCs treatment methods generally achieve treatment by means of adsorbent adsorption and condensation.

[0003] The existing Chinese patent application with the publication number CN112403196A discloses a VOCs waste gas treatment purifier, which includes a reaction tank, a rotating plate and a partition plate; a partition plate is fixedly connected to the middle of the reaction tank, and the partition plate divides the reaction tank into a non-communicating left chamber and right chamber; a condensation 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 to the inside of one end of the rotating plate relative to the rotating ring, and the first magnet block and the second magnet block are designed in one-to-one correspondence; a graphite layer and an activated carbon layer are arranged inside the rotating plate; a collection bin is fixedly connected to the outer surface of the lower end of the reaction tank; an air outlet pipe is fixedly connected to the upper end of the left side wall of the reaction tank; in this invention, gas adsorption and desorption are carried out by rotating the rotating plate, so as to obtain pure VOCs gas, improve the utilization rate of VOCs gas, and avoid frequent replacement of the adsorbent.

[0004] However, the condensation adsorption device has the following defects in specific use:

[0005] 1. When the existing condensation adsorption device separates VOCs (volatile organic compounds) impurities in waste gas, it generally separates the two by adsorbing VOCs (volatile organic compounds) impurities in the waste gas with an adsorbent. At this time, it is difficult to reuse the adsorbent for adsorbing VOCs (volatile organic compounds) impurities, and the loss of the adsorbent is relatively large. At the same time, other metal particle impurities in the waste gas will also adhere to the surface of the adsorbent. On the one hand, it is not convenient for the subsequent recovery operation of this part of metal particle impurities. On the other hand, the weight of the adsorbent will increase sharply, affecting the reuse operation of the adsorbent;

[0006] 2. When the existing condensation adsorption device treats the VOCs (volatile organic compounds) impurities in the waste gas, it generally uses the condensation method to condense the gaseous VOCs and separate them from the mixed waste gas to achieve the separation operation of VOCs (volatile organic compounds). However, in actual operation of the traditional scheme, the operation of condensing VOCs (volatile organic compounds) takes a lot of time, and the separation operation efficiency of VOCs (volatile organic compounds) is low.

[0091] In the VOCS condensation adsorption device of the present invention, when the stirring roller 603 rotates to stir the waste gas, it will also drive the lower connecting rod 801 connected to its bottom to rotate, and make the transmission gear 802 installed at the bottom of the lower connecting rod 801 rotate. When the transmission gear 802 rotates, it will drive another group of transmission gears 802 meshed with its side to rotate, and make the side connecting rod 803 connected to the bottom of the other group of transmission gears 802 rotate. At this time, when the side connecting rod 803 rotates, it will drive the bevel gear 804 installed at its bottom to rotate, and make another group of bevel gears 804 and the horizontal rod 806 meshed with the side of the bevel gear 804 rotate.

[0092] Limited to this, any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
