Organic gas withdrawal processing technique and device thereof

Abstract

The invention relates to an organic waste gas recycling and processing technique and a device thereof, absorption materials are adopted to absorb organic solvents in waste gas, the waste gas can be changed into clean gas after the absorption to be directly exhausted to atmosphere, when the absorption materials absorb a certain amount of the organic solvents, the absorption materials are carried out the desorption, thus desorbing the absorbed organic solvents, the absorption capacity of the absorption materials is recovered, then the absorption materials are re-input the absorption operation for the sequential circulating operation; at least two groups of absorption materials are adopted for alternate operation, when one group of the absorption materials are in the absorption process, the other group of the absorption materials are in the desorption process; the absorption materials take superfine molecular sieve powder or activated carbon powder as raw materials and are prepared by adding inorganic fibers or activated carbon fibers and inorganic binders, and the structure thereof is a cellular structure. The device can not only maintain the durable absorption capacity of the absorption materials, but can also have strong absorption capacity, low production cost and long service life.

Description

technical field [0001] The invention relates to an organic waste gas treatment technology, in particular to an organic waste gas recycling process and a device thereof. Background technique [0002] Volatile Organic Compounds (Volatile Organic Compounds, VOC) generally refer to organic compounds with a vapor pressure greater than 0.1mmHg under standard conditions (20. C, 760mmHg), and the environmental pollution problems caused by them widely exist in various industries, such as automobiles Painting, household appliance production, furniture production, iron printing cans, packaging printing, adhesive tape production, lithium battery production, shoemaking, electronic components, container production, etc. will all generate a large amount of organic waste gas. If these organic waste gases are directly discharged into the atmosphere, they will cause direct or indirect harmful effects on human health and the environment. [0003] With the rise of oil prices, people are more a...

AI Technical Summary

Problems solved by technology

[0004] (1) The resistance of the adsorption bed is large, and the power of the equipment fan is large, resulting in high operating costs;

[0005](2) The service life of activated carbon and activated carbon fiber is short, and the activated carbon or activated carbon fiber needs to be replaced regularly; activated carbon is combustible, and the activated carbon adsorption bed has potential safety hazards

[0006] (3) The operation of the equipment requires steam, and the consumption of steam is large;

[0007](4) The equipment is bulky, covers a large area and is heavy, which results in special requirements for the installation site and high equipment investment costs
