Hongfeng said exhaust gas purification tower waste gas treatment equipment, mainly the use of different techniques to reduce the harmful ingredients emissions through recycling or removal, to protect the environment, environmental protection equipment for air purification.

Types of waste gas treatment equipment

1. Absorption equipment

VOCs was absorbed by low volatile or non volatile solvents, and then separated by physical properties of VOCs and absorbent.

2. Adsorption equipment

In the use of porous solid material processing fluid mixture, fluid in one component or some components may be absorbed and concentrated on the surface, this phenomenon is known as adsorption. Adsorption treatment of waste gas, the adsorption of the object is gaseous pollutants, gas solid adsorption. The adsorbed gas component is called adsorbate, and porous solid material is called adsorbent.

3. Combustion and catalytic purification equipment of organic waste gas

For the treatment of high concentration Voc and malodorous compounds are effective combustion method, its principle is to use the excess air to generate most of these impurities are burning, carbon dioxide and water vapor, can be discharged into the atmosphere. However, when dealing with organic compounds containing chlorine and sulfur, HCl or SO2 in combustion products need further treatment of the gas after combustion.

4. Low temperature plasma treatment equipment for industrial organic waste gas

Hoffen exhaust gas purification tower is a gas in plasma was informed that the ionization state of the English, its name is plasma, it is by the scientific Muir, in 1927 on the phenomenon of low pressure mercury vapor discharge is named. The plasma is composed of a large number of sub, neutral atoms, excited atoms and photons and the free radicals and other components, but the number of electron and positive ion must exhibit electrically neutral, this is the meaning of "plasma". There are many aspects of the electric conduction and electromagnetic influence which are different from the solid, liquid and gas, so some people call it the fourth state of matter.  According to the state, temperature and ion density, plasma can be divided into high temperature plasma and low temperature plasma (the stuffed body and the cold plasma). The high temperature plasma ionization degree of various particle temperature close to 1, almost the same system in thermodynamic equilibrium, it is mainly used in the study of controlled thermonuclear reaction. The low temperature plasma is non-equilibrium, and the temperature of various particles is not the same.  The electron temperature (Te) = ion temperature (Ti), more than 104K, and the ion and neutral particle temperature can be as low as 300 ~ 500K. The general gas discharge electron belongs to the low temperature plasma.

5. Photocatalytic and biological purification equipment

Photocatalysis is a deep temperature reaction technique at room temperature. Photocatalytic oxidation at room temperature will completely oxidize organic pollutants into harmless products of water, air and soil, and the traditional high-temperature incineration technology is needed in high temperature contaminations can be destroyed only, that using conventional catalytic oxidation method, also need hundreds of high temperature.
