Problems solved by technology

[0003] At present, the fixed adsorption bed technology is basically used in the VOC organic waste gas treatment application market. No matter the process route chooses activated carbon, carbon fiber, adsorption resin, zeolite molecular sieve or honeycomb adsorption wheel, etc., its basic form is a fixed bed structure. The disadvantages of fixed adsorption beds gradually appear during long-term use, which affect the promotion and development of VOC organic waste gas treatment process with fixed bed structure
The fixed bed adsorption technology has the following d

Abstract

The embodiment of the invention discloses a box-type moving bed waste gas purification system which comprises an adsorption purification unit and a regeneration cooling unit, the adsorption purification unit is provided with multiple adsorption layers, and the adsorption purification unit is used for moving a perforated filler box of the upper adsorption layer downwards to the relative position of the lower adsorption layer, feeding a perforated filler box of the bottom adsorption layer into a regeneration cooling unit, andpurifying organic waste gas flowing from bottom to top through each stage of adsorption layer; the regeneration cooling unit is provided with a plurality of desorption cooling layers and is used for heating the filler of each stage of desorption cooling layer through hot nitrogen or water vapor flowing from bottom to top and cooling the filler of each stage of desorption cooling layer through air flowing from bottom to top after desorption is finished; and after cooling is finished, the perforated stuffing box of the upper desorption cooling layer is moved downwards to the relative position of the lower desorption cooling layer, and the perforated stuffing box of the bottom desorption cooling layer is fed into the adsorption purification unit.

Description

technical field [0001] The embodiments of the present application relate to the technical field of air treatment, and in particular to a box-type moving bed waste gas purification system. Background technique [0002] Production workshops (such as: gluing and bonding workshops in shoe factories, printing workshops in printing factories, paint and coating production workshops, various organic chemical products production workshops, fiberglass product production workshops, painting, spraying workshops, musical instruments, wooden furniture surface treatment workshops Adhesive tapes, leather, adhesive production workshops, etc.) will produce many harmful gases during the manufacturing process of products, such as a variety of common VOC organic waste gases. The quality of indoor air quality and the emission of exhaust gases have become the current research one of the important subjects. [0003] At present, the fixed adsorption bed technology is basically used in the VOC organ...
