Chain-driven grate bed for cooling and activation of VOCs waste gas adsorbent

Abstract

The invention relates to the technical field of environmental protection, specifically to a chain-driven grate bed for cooling and activation of a VOCs waste gas adsorbent. The chain-driven grate bedis characterized by comprising material columns and a chain-driven grate bed body, wherein the chain-driven grate bed body is designed with a kiln box and a chain-driven grate bed raft; the kiln box is designed with a smoke outlet; the chain-driven grate bed raft comprises a chain wheel, a chain, a grate bed raft and air distribution plates; two ends of a horizontal pin are fixedly bonded on the chain; the chain wheel drives the chain to rotate, so the grate bed raft is driven to move; discharged tail gas treated by a VOCs waste gas environmentally-friendly purification facility is introducedthrough the air distribution plates, then sent into the kiln box from gaps among adjacent grate bed raft sheets, purged, cooled and spread to an adsorbent on the chain-driven grate bed raft, and discharged out through the smoke outlet.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a chain-driven grate bed for cooling and activating a VOCs waste gas adsorbent. 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 abso...

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
