Description
Technical Field
The invention belongs to the technical field of waste gas treatment, and particularly relates to a waste gas treatment method.
Background
The main traditional methods for treating exhaust gas are: the spray tower is used for treating waste gas by using the principle of absorption, and the absorption method treatment is a process of treating a gas mixture by using a liquid absorbent to remove one or more gases in the gas mixture. During this process, a physical effect occurs in which some gas is dissolved in the solution, which is physical absorption. There is also a chemical reaction between the chemicals in the gas and liquid, which is chemical absorption. Absorption is commonly used for the treatment and recovery of gaseous pollutants.
The absorption method is characterized by absorbing harmful gas and removing dust in exhaust gas, and is divided into physical absorption and chemical absorption. Physical absorption is a purely physical dissolution process when harmful gases and vapors are absorbed with a liquid. It is suitable for harmful gas and vapor with high solubility in water and has low absorption efficiency. Chemical absorption is a process in which there is a significant chemical reaction accompanying the absorption process, and is not a pure dissolution process. The chemical absorption efficiency is higher, and the method is a harmful gas treatment method which is applied more at present.
And for the waste gas of the VOCs, physical absorption is mainly adopted, and different gases are used for selectively absorbing the waste gas of the VOCs according to different solubilities of the absorbents.
For VOC waste gas, in the prior art, absorption liquid is atomized into small water drops through a nozzle, the small water drops are sprayed in a high density mode in a space and act with the waste gas, the acting time is the space height, the acting time is short due to the fact that gas-liquid interaction physical acting time is too short, the absorption efficiency is poor, energy consumption is large, or the height is increased, investment is increased, the specific surface area is increased, the nozzle is small, the design difficulty is large, the blockage is easy, the VOC can be fully absorbed, and the maintenance cost is high.

step four: utilize ultrasonic wave shortwave to vibrate, destroy or extrude exhaust gas package and reaction gas package for the liquid film between exhaust gas package and the reaction gas package destroys the mixture, and the pressurization increases reaction power, gets rid of the pollutant with higher speed.
And in the third step, the gas inlet type and the liquid inlet amount of the reaction gas are adjusted to obtain reaction gas bags with different types and volumes, and the recyclable organic gas in the waste gas bag is absorbed by using a gas phase mode.
The invention has the following advantages:
the mode of traditional atomizing liquid is reformed to the creation miniature gas bag mode, can be in littleer space through a set of device, and different fluids are selected in the self control, contain gas and liquid, get rid of, the retrieval and utilization organic waste gas (VOCs), solve waste gas, reach the purpose of high-efficient multipurpose.
