Problems solved by technology

In terms of pollution control technologies through various removal of volatile solvents (such as condensation method, adsorption method, absorption method, combustion method, biological method, membrane separation method, plasma method, photocatalytic oxidation method), although the treatment systems and methods continue to Renewal, the removal rate or recovery rate is constantly improving (some methods are as high as 98%), but there is always residual VOCs emissions, more of which cannot meet the emission standards, and some sewage treatment methods even produce secondary pollution
With the further strengthening of the government's supervision of air pollution control, the emission standards of various regions and industries have been further improved, making it difficult for the existing treatment systems and methods to adapt to the ever-increasing emission standards.

Embodiment 1

[0038] Please refer to figure 1 As shown, the VOCs exhaust gas treatment system of the present embodiment 1 includes an organic matter treatment device 2 for removing VOCs, a fan 3, and a tail gas recovery pipeline 4, and the organic matter treatment device 2 is an existing absorption recovery method, adsorption recovery One or more of the devices used in the method, condensation recovery method, incineration method, catalytic incineration method, plasma method or biological method.

[0039] The organic matter treatment device 2 and the tail gas recovery pipeline 4 are connected sequentially, and the gas inlet end of the organic matter treatment device 2 and the gas outlet end of the tail gas recovery pipeline 4 are respectively connected with the VOCs waste gas source 5, and the VOCs waste gas source 5, organic matter The processing device 2 and the exhaust gas recovery pipeline 4 form a closed loop (exhaust gas circulation system), and the fan 3 is arranged on the closed loo...

Embodiment 2

[0050] When the organic matter treatment device 2 is an adsorption recovery device including an adsorption tank, and the organic matter treatment method is to adsorb VOCs:

[0051] Please refer to figure 2 As shown, on the basis of Embodiment 1, the VOCs exhaust gas treatment system of Embodiment 2 also includes an adsorption system, a desorption system, a condensation system and a separation system of the adsorption recovery method, and the dehumidification of the adsorption tank of the second fan 10, cooling system.

[0052] The second fan 10 is connected to the adsorption tank of the organic matter treatment device 2, and a cooling and dehumidification channel is opened on the adsorption tank, one end of the cooling and dehumidification channel is connected to the second fan 10, and the other end of the cooling and dehumidification channel is connected to the outside world Pass.

[0053] Please continue to refer to figure 2 Shown, the VOCs waste gas treatment method of...

Embodiment 3

[0058] When the organic matter treatment device 2 is an organic matter treatment device 2 used to absorb or incinerate VOCs, and the organic matter treatment method is to absorb or incinerate VOCs:

[0059] can be used as figure 1 For the VOCs waste gas treatment system shown, the treatment method can refer to the description in Example 1.

[0060] The difference between this embodiment 3 and embodiment 2 is that the second blower fan 10 is not included, because there will be no intermittent temperature rise and water in the desorption process of the adsorption recovery method in the organic matter treatment device 2 for absorbing or incinerating VOCs. Steam is a problem, so there is no need for cooling and removal of water vapor.

Abstract

The invention relates to a VOCs waste gas treatment device. The VOCs waste gas treatment device comprises a VOCs waste gas source, an organic matter treatment device, a fan and an exhaust recovering pipeline, wherein the organic matter treatment device and the exhaust recovering pipeline are sequentially connected, a gas inlet end of the organic matter treatment device is connected with a waste gas emission outlet pipeline of the VOCs waste gas source, a gas outlet end of the exhaust recovering pipeline is connected with a fresh air inlet end pipeline of the VOCs waste gas source, a closed circulating loop is formed by the VOCs waste gas source, the organic matter treatment device and the exhaust recovering pipeline, the fan is arranged on the closed circulating loop, and the organic matter treatment device is also connected with an organic solvent collecting device pipeline. The VOCs waste gas treatment device provided by the invention realizes zero emission of VOCs waste gas, and thoroughly eliminates the pollution of VOCs waste gas emission to the environment; and the whole treatment process is simple and easy to operate, high in treatment efficiency, less in required equipment, and low in energy consumption of equipment, and well meets the requirements of modern enterprises for energy conservation and emission reduction, and improvement of production effectiveness, thus being of great significance for saving resources and lowering cost.

Description

technical field [0001] The invention relates to a VOCs waste gas treatment device, and relates to the technical field of environmental protection treatment. Background technique [0002] As we all know, PM2.5 (fine particulate matter) and smog weather have an increasingly serious impact on people's life and health, and VOCs (volatile organic compounds) are one of the main factors that make the concentration of PM2.5 abnormal. The total emission of VOCs has reached more than 20 million tons per year. In various occasions where organic solvents are used, such as painting, printing, metal degreasing and degreasing, adhesives, pharmaceuticals, plastics, rubber, petroleum and other processing and production sites, volatile organic compounds (VOCs for short) are polluting the air. In terms of pollution control technologies through various removal of volatile solvents (such as condensation method, adsorption method, absorption method, combustion method, biological method, membrane...
