Problems solved by technology

Industrial emissions are the main source of VOCs pollution, and industrial enterprises are also conducting related treatment of VOCs gases. However, the traditional VOCs gas treatment methods have low purification rates and are likely to cause secondary pollution. They cannot effectively control VOCs gases. How to deal with industrial emissions The effective treatment of VOCs gas has become an important issue we need to solve

Embodiment Construction

[0026] use Figure 1-Figure 5 A method for purifying VOCs gas according to an embodiment of the present invention will be described as follows.

[0027] like figure 1 and figure 2Shown, the purifying method of a kind of VOCs gas of the present invention, this method comprises the steps:

[0028] Step 1: Centrally collect VOCs gas;

[0029] Step 2: after collecting in step 1, remove large particles such as dust from VOCs gas;

[0030] Step 3: After removing large particles in step 2, the VOCs gas is purified by photocatalysis and biological bed composite VOCs purification equipment;

[0031] Step 4: After the purification in step 3 is completed, detect the purified gas, discharge the gas that meets the emission standard, and perform secondary purification on the gas that does not meet the standard;

[0032] Wherein, the photocatalytic and biological bed composite VOCs purification equipment described in step 3 includes a reaction chamber 1, an elution tank 2, a photocatal...

Abstract

The invention belongs to the technical field of VOCs gas treatment, and specifically relates to a method for purifying VOCs gas. The method includes the following steps: collecting VOCs gas in a concentrated manner; removing large particles such as dust from VOCs gas; The biological bed compound VOCs purification equipment purifies VOCs gas; detects the purified gas, discharges the gas that meets the emission standard, and performs secondary purification on the gas that does not meet the standard; the invention is suitable for the purification of a large amount of VOCs gas , At the same time, the purification rate of the present invention is high, effectively avoiding the harm of VOCs gas to the environment and human beings.

Description

technical field [0001] The invention belongs to the technical field of VOCs gas treatment, in particular to a method for purifying VOCs gas. Background technique [0002] VOCs (Volatile Organic Compounds) refer to volatile organic compounds, mainly including hydrocarbons, aromatic hydrocarbons, alcohols, aldehydes, ketones, lipids, amines and organic acids, etc., which have strong volatility, special odor, irritation and Toxicity and other characteristics will not only badly affect the ecological environment, but also cause serious harm to human health. Industrial emissions are the main source of VOCs pollution, and industrial enterprises are also conducting related treatment of VOCs gases. However, the traditional VOCs gas treatment methods have low purification rates and are likely to cause secondary pollution. They cannot effectively control VOCs gases. How to deal with industrial emissions The effective treatment of VOCs gas has become an important issue we need to solv...
