Problems solved by technology

[0003] Existing technology-Aiming at the practical problems of large air volume VOCs waste gas treatment, the technical solution of the electrothermal purification filter element is proposed for the enclosure structure, the air inlet surface, and the air outlet surface with one or more layers of porous sieve plates or adsorption beds filled with sieves. However, there is no solution for how to replace the electrothermal purification filter element in normal production after the adsorption of VOCs exhaust gas is saturated; prior art 2 proposes the use of molecular sieve runners and honeycomb activated carbon runners for VOCs exhaust gas adsorption and desorption for the practical problems of VOCs exhaust gas treatment , Concentration, and combustion technical solutions, it is undoubtedly feasible to use a mechanical runner to solve the technical solution of replacing the adsorbent after the VOCs exhaust gas is saturated, but the sealing problem must be solved for moving equipment such as the runner, especially the rotary The problem of VOCs exhaust gas leakage due to seal failure under continuous production conditions during wheel replacement

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 Shown, a kind of treatment VOCs exhaust gas cycle regeneration process system operation method is characterized in that:

[0039]Step 1. Before operation, the static test run debugging of desorption pyrolysis furnace Ⅰ and chain drive grate bed Ⅱ and joint debugging and joint test of induced draft system Ⅲ and adsorbent moving bed Ⅳ should be carried out. The flue 7 is filled with high-alumina ball packing, and the particle diameter of the high-alumina ball packing is 20-25 mm. The adsorbent to be desorbed is delivered to the vertical channel 6 in the desorption pyrolysis furnace body 5 through the feeding system 1, and the vertical channel 6 is And the material leg 15 is filled with adsorbent particles, cut off the flue collecting duct 10 to t...

Abstract

The invention relates to the technical field of environmental protection, and particularly to an operation method of a recycling process system for treating a VOCs (volatile organic compounds) waste gas. The operation method is characterized in that the effective treatment of the VOCs waste gas and the recycling of an adsorbent are realized through a desorption thermal decomposition furnace, a chain drive grate bed and an adsorbent moving bed.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an operating method for a VOCs waste gas recycling process system. Background technique [0002] Gaseous pollutants emitted by industry are the main source of atmospheric environmental pollutants, among which volatile organic compound waste gas (VOCs) is a gaseous pollutant that is seriously harmful to the environment, and it is also an occupational hazard that affects the health of operators in the workplace It is widely derived from chemical industries such as paints, coatings, coatings, lubricants, and rubber. Due to its huge destructive effect on the human body and the natural environment, the country has issued relevant laws and regulations to strictly control its governance and emissions. At present, the commonly used treatment methods of organic waste gas treatment technology include combustion method, chemical oxidation method, chemical absorption method...
