Embodiment 2

[0052] 1. An organic waste gas purification method integrating plasma and biological filtration, that is, using the purification system described in claim 1 to treat organic waste gas (such as figure 2 shown), the specific method is as follows:

[0053] When the organic waste gas purification system is turned on, the fan continuously feeds the organic waste gas into the injector, and the organic waste gas is sprayed and processed by the plasma reactor and the biological filter bed in turn, and the treated gas is discharged from the gas outlet. The water pump running at the same time continuously circulates the liquid in the water tank to the ejector, and the nutrient solution supplier and air bubble supplier continuously deliver microbial nutrient solution and air bubbles to the water tank to maintain the normal and continuous operation of the biological filter bed.

[0054] 2. In this purification method, not only the respective advantages of plasma and biological filter bed...

Abstract

The invention discloses an organic waste gas purifying system and method integrating plasma and biological filtration. The organic waste gas purifying system comprises a spraying system, a plasma reaction system and a biological filtration system, wherein a spraying device of the spraying system, a plasma reactor of the plasma reaction system and a biological filtration bed of the biological filtration system are sequentially arranged in a reaction tank from top to bottom. The organic waste gas purifying system is of an integral structure, and the plasma reactor and the biological filtration bed are arranged in a reactor in an up-down combined mode, so that under the condition of low pressure losses, the purification capacity is increased without increasing huge costs, the respective advantages of the plasma and the biological filtration bed can be kept, the complementary and coordinated effects are achieved, the treating effect is remarkable and stable, the load impact resisting capability is high, the size of the system can be reduced significantly, the occupied area is reduced, the system is simple in structure and convenient to install, and the cost is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment. More specifically, it relates to an organic waste gas purification system and method integrating plasma and biological filtration. Background technique [0002] In the industrial production process, especially the coating production process, a large amount of organic waste gas will be generated, which has the characteristics of complex composition, unstable air volume, and low concentration, making waste gas treatment difficult and costly. Due to the lack of effective treatment measures, many companies basically adopt direct high-altitude emissions. And because its concentration is lower than the emission standard, it is difficult to detect its emission concentration in real time, and it is generally difficult for environmental protection departments to supervise. For some places with high environmental protection requirements, enterprises usually use activated carbon adsorption to d...
