Problems solved by technology

[0006] In the existing volatile organic waste gas treatment process, most enterprises discharge volatile organic waste gas VOCs in an unorganized manner, causing pollution to the surrounding environment, affecting the health of the surrounding people, causing complaints from the masses, and eventually leading to suspension of production for rectification; there is also a small Some enterprises collect and treat the volatile organic waste gas VOCs generated, but the waste gas treatment technology adopted is difficult to treat the waste gas up to the discharge standard. Excessive emissions will have adverse consequences for the atmospheric environment
[0007] In addition, during the operation of existing industrial plants, such as spraying industry, if the new supplementary gas contains dust and the temperature is too low, it will have a great impact on the quality of spraying
Therefore, it is necessary to remove dust and make up the temperature of the newly circulated air, which also increases the production cost of the enterprise.

Embodiment 1

[0027] Such as figure 1 The shown process for temperature supplementation, dust-freeization and VOCs near-zero emission of an industrial plant mainly includes the following steps:

[0028] (1) Use the fan 3 to collect the volatile organic waste gas (VOCs) in the industrial plant, and collect the waste gas;

[0029] (2) Transport the waste gas collected in step (1) to the waste gas treatment integrated system 4 for the treatment of volatile organic waste gas VOCs. Specifically, the waste gas is first sprayed and absorbed by water or surfactants, and then passed through Fe- C material for adsorption, and finally catalyzed by Fe-C material and oxidant for catalytic oxidation treatment; the oxidant is hydrogen peroxide or calcium hypochlorite or a mixture of the two; the volatile organic waste gas treated in step (2) is finally converted Small molecule, non-toxic and harmless CO 2 and H 2 O;

[0030] (3) The gas treated in step (2) is input into the factory building through t...

Embodiment 2

[0031] Embodiment 2 pilot test

[0032] In order to further verify the feasibility of the patented technology, a pilot test was carried out in the pilot laboratory of Nanjing Glote Environmental Engineering Co., Ltd.

[0033] Experimental program:

[0034] Such as figure 2As shown, in the experiment, a spraying container 2 with a size of 1m*1m*1m was used to simulate the factory building. The container 2 was made of plastic pp material, and the paint was atomized by a pump and an atomizing device in the container 2, forming a large amount of volatile organic waste gas The fan 3 is connected outside the container, the outlet of the fan 3 is connected with the waste gas treatment integrated system 4 , and the waste gas outlet of the waste gas treatment integrated system 4 is connected with the container 2 through the return fan 5 . The outside of the container 2 is wrapped by an outer shell packing box 1 of 1.5m*1.5m*1.5m. The details of the device are as figure 2 show...

Abstract

The invention discloses an industrial plant heating and dustless and volatile organic chemicals (VOCs) near zero emission process, which substantially comprises steps: (1) VOCs in industrial plants is collected by utilizing a gas collecting system, and waste gas is collected; (2) the waste gas which is collected in the step (1) is conveyed to a waste gas treatment device, and the VOCs is treated; and (3) gas which is treated in the step (2) is conveyed to plants through a gas send-back system, and is recycled. The industrial plant heating and dustless and volatile organic chemicals (VOCs) near zero emission process enables plants not to have dust and heating, and enables VOCs to be discharged near zero or at zero.

Description

Technical field [0001] The patent of the present invention is suitable for industrial production, and it is suitable for production enterprises with volatile organic exhaust gas (VOCs) in all or local areas in the plant. It is particularly suitable for dust -free and constant temperature and generate VOCS. It belongs to the field of environmental protection. Background technique [0002] VolatileorganicCompounds (VOCS) refers to the collective name of all organic compounds with corresponding volatile compounds under 20 ° C, or that the steam pressure is greater than or equal to 0.01kPa, or under specific applications.There are many types of VOCs produced in various industries, complicated, and common ingredients are carrocarmark compounds, benzene, alcohols, ketones, phenols, aldehyde, esters, amine, cyanocytes, etc.Most of the volatile organic pollutants (VOCs) are toxic and harmful, which will not only increase the oxidation of environmental atmosphere, but also cause the toxic...
