Problems solved by technology

The main characteristics of VOC in terms of environment, safety and hygiene are (1) toxic
(2) Derivative air pollution
(3) Destruction of the ozone layer
(4) Explosive, so there must be appropriate treatment technology for VOC, and it is regulated by national laws and regulations
[0004] There are two types of VOC control technologies: recycling and destructive. The former is commonly used for activated carbon adsorption, and then d...

Embodiment Construction

[0014] Please refer to Figure 1, which is a preferred embodiment of the volatile organic waste gas adsorption treatment system of the present invention, that is, a system diagram of activated carbon regeneration and heat recovery, and its composition at least includes:

[0015] The fluidized adsorption bed 1, mainly utilizes the large specific surface area of ​​activated carbon (100-1000m2 / g), produces large-area flow and increases the adsorption effect to meet the regulations and standards of clean air; as shown in the figure, the VOC waste gas is fluidized After the bottom side of the adsorption bed 1 is fed in, the VOC pollutants are adsorbed and removed by the adsorption of the evenly distributed bead-like activated carbon in the series of punching plates 10 above, and the air after the purification of VOC is removed from the fluidized adsorption bed 1 Discharge from the top. When the activated carbon adsorbs a large amount of VOC pollutants, it will be discharged from the bot...

Abstract

The invention provides a novel adsorption treatment system for volatile-organic-compound waste gas, mainly for solving the problem that the traditional active-carbon flow-type adsorption device along with a condensation recovery device may cause secondary pollution of the waste solution and big energy consumption. The invention is characterized in that volatile organic compound (VOC) is adsorbed in a fluidized way by granule-shaped active carbon and then sent to fluidized desorption bed for desorption by adopting the hot gas produced by a heat exchanger and a positive pressure windmill; the desorbed VOC of high concentration uses back-drafting windmill for entering a VOC oxidation heater; the VOC is urged to relieve the heat after being pyrolyzed in high temperature; then the heat is recovery and provides for the devices mentioned above. As the active carbon used for adsorption and desorption in the system of the invention is completely separated, with the nitrogen fire-extinguishing mechanism arranged and the heat source can be produced by the combustibility of the waste gas discharged during the production instead of using gas or heavy oil, the cost is reduced and the processing efficiency of the discharge standard for the environmental protection is quite high, so that the industrial competitive advantage can be improved greatly.

Description

Technical field [0001] The invention relates to an adsorption treatment technology for volatile organic compounds (Volatile Organic Componds, VOCs) waste gas, and the technology relates to a brand-new activated carbon regeneration and heat recovery system. Specifically, it relates to an activated carbon adsorption treatment system for volatile organic compound exhaust gas that can be cracked and used as fuel to reduce energy consumption and does not cause secondary pollution. Background technique [0002] The largest use category of volatile organic gases (Volatile Organic Componds, VOCs) is organic solvents, and they are widely used in various industries, such as coating industry, paint industry, chemical industry and semiconductor packaging industry solvent recovery and semiconductor manufacturing, Dilution and cleaning in the photovoltaic industry. [0003] At present, the main types of organic solvents commonly used in China include: (1) Alcohols-methanol, isopropanol, butano...
