Adsorption type efficient waste gas purification device based on magnetic particles

Abstract

The invention discloses an adsorption type efficient waste gas purification device based on magnetic particles, and belongs to the technical field of waste gas treatment. According to the adsorption type efficient waste gas purification device based on the magnetic particles, a plurality of high-strength adsorption balls are adsorbed through an electromagnet disc to form an adsorption layer; the adsorption layer can be rotated, and blockage caused by non-uniform adsorption degree of the adsorption layer in each direction is avoided; meanwhile, different magnetic adsorption areas are sequentially arranged on the electromagnet disc from inside to outside, the magnetic adsorption areas are sequentially powered off from outside to inside during use according to the time limit, falling of the high-strength adsorption ball from outside to inside is realized, furthermore, uniform utilization of the high-strength adsorption balls laid inside and outside is further fully achieved, and adsorption blockage is avoided. When the falling high-strength adsorption balls are desorbed, breakage of the adsorption materials at the outer ends of the magnet balls is completed in combination with certaintemperature and rotary collision shearing, and subsequent collection and utilization of the magnet balls and the adsorption materials are facilitated.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, and more specifically, relates to a high-efficiency waste gas purification device based on magnetic particle adsorption. Background technique [0002] With the accelerating pace of social development, the environmental pollution caused by industrial development is becoming more and more serious, and people are gradually paying more and more attention to whether industrial emissions exceed the standard. Pollution pollutes, thereby affecting people's living environment, so the exhaust gases need to be treated before they are discharged. [0003] In the prior art, adsorbents are often used to adsorb harmful substances in the exhaust gas. During the use of the adsorbents, an adsorption filling layer is often set up, and the gas flows through the adsorption filling layer to adsorb particles.

Problems solved by technology

[0003] In the prior art, adsorbents are often used to adsorb harmful substances in the exhaust gas. During the use of the adsorbents, an adsorption filling layer is often set up, and the gas flows through the adsorption filling layer to adsorb particles. However, the adsorption filling layer in the existing device The layers are generally fixed. The side of the adsorption filling layer that first touches the gas will absorb too much, and the side that touches the gas later will absorb less, and the gas generally flows in one direction, which will cause adsorption blockage. At the same time, the utilization rate of the adsorption layer that is not completely adsorbed on the other side is low, which results in a poor adsorption circulation effect; in addition, some of the existing adsorbents can be desorbed and reused after use, when the utilization rate is low After use, the adsorbent is directly crushed and annihilated and no longer recycled, while the desorption effect in the prior art is poor, which leads to a low utilization rate in the later stage
