Problems solved by technology

[0003] VOCs exhaust gas treatment is of great significance to human health. At present, there are systems for VOCs exhaust gas treatment. However, due to the presence of other pollutants and impurities in the air, when VOCs exhaust gas is treated, poor filtration in the early stage often occurs, resulting in VOCs in the later stage. Additional reaction occurs during treatment to produce new pollutants, resulting in poor tail gas treatment effect

Embodiment 1

[0027] A VOCs tail gas treatment device is provided with a VOCs tail gas collection device 1, a dust removal chamber 2, a cooling treatment device, a biochemical spray filter mechanism, a demister mechanism 13, an adsorption mechanism 14, and an online monitoring mechanism 15, which are sequentially connected by pipelines. The dust removal chamber 2 is provided with a dust remover for removing solid particles in the tail gas. The biochemical spray filter mechanism includes a sequentially connected chemical agent scrubber 5 and a biological agent scrubber 10; the chemical agent scrubber 5 includes a chemical scrubber body, a first atomizing nozzle 7, a chemical agent storage tank 6, a first The air inlet 4, the second air inlet 8, the first outlet, and the chemical agent collection port; the first air inlet 4 and the second air inlet 8 are located on one side of the chemical scrubber body, and the first air inlet 4 and the cooling The outlet of the processing device is connecte...

Embodiment 2

[0036] It is basically the same as Example 1, except that the chemical agent uses dimethylformamide, and the biological agent uses Citrobacter freundii and its culture solution.

Embodiment 3

[0038] It is basically the same as in Example 1, except that dimethyl sulfoxide is used as the chemical agent, and Bacillus and its culture fluid are used as the biological agent.

Abstract

The invention discloses a VOCs (volatile organic compounds) tail gas treatment device and method. According to the method, the tail gas passes through a VOCs tail gas collection device, a dedusting chamber, a cooling treatment device, a biochemical spray filtering mechanism, a demisting mechanism and an adsorption mechanism sequentially, the VOCs tail gas is treated through dedusting, chemical, biological and physical treatment processes, and the method has the remarkable advantages of low energy consumption, high treatment efficiency, stable work and the like.

Description

technical field [0001] The present invention relates to the technical field of tail gas treatment, in particular to a VOCs tail gas treatment device and method. Background technique [0002] With the development of society, people's awareness of environmental protection is gradually increasing. On the one hand, economic development will inevitably produce a certain amount of pollution at the current stage of people's understanding; on the other hand, human progress has also put forward higher requirements for the living environment in which they live, and the masses have strong reactions to environmental pollution. Environmental protection departments at all levels have also imposed stricter restrictions on pollutant discharge. How to achieve the unity of economic benefit and environment is a new problem faced by human beings. [0003] VOCs exhaust gas treatment is of great significance to human health. At present, there are systems for VOCs exhaust gas treatment. However,...
