Problems solved by technology

Most of the existing technologies use a suction fan to extract the organic waste gas from the coating machine, and then process it. The existing treatment methods mainly include: absorption method, adsorption method, condensation method, membrane separation method, incineration method, biological treatment method , plasma treatment, etc., none of the above methods can achieve thorough treatment of organic waste gas at a lower cost

Abstract

The invention discloses a comprehensive utilization system and method for waste treatment for wallpaper processing. The comprehensive utilization system includes: a filter, a reactor, and the reactor is sequentially connected from top to bottom by a crushing pyrolysis chamber, an air chamber, and a secondary carbonization chamber. The inner cavity of the secondary carbonization chamber is fixed with a horizontal heating pipe, the outer side of the activation chamber is fixed with a secondary combustion chamber, the outlet at the bottom of the filter and the activated carbon inlet on the side of the secondary carbonization chamber connected. The production method is: the finished activated carbon filters the air containing high concentration of organic waste gas; the bed material and waste wood undergo crushing and pyrolysis reactions in the crushing pyrolysis chamber to generate carbonized material and biomass gas; The organic matter in the activated carbon undergoes pyrolysis and carbonization reaction; activation reaction. The invention can realize the coordinated treatment of waste wood and organic waste gas, and can realize the joint production of heat energy and high-quality activated carbon.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of wallpaper processing waste, and in particular relates to a system and method for comprehensive utilization of wallpaper processing waste. Background technique [0002] Wall decoration materials include wall coverings, wallpapers, decorative panels, ceramic tiles, etc. Wallpaper manufacturers often also involve the production of wooden wall panels and decorative panels. The production of wall coverings, wallpapers, and decorative panels involves coating processes. Coating The core item of the process is the coating. The coating not only needs to have chemical stability, good curing speed, and good wettability, but also needs to have a certain affinity for different substrates. Various solids used for adhesion in the coating The substance must be mixed well with the help of a solvent before it can be applied to the carrier manually or by equipment. [0003] The coating process ...
