What are the methods of industrial waste gas treatment? volume_up content_copy share

Due to the rapid development trend of the industry, there is a lot of organic waste gas that has not been processed in sewage treatment, which leads to environmental hazards and great harm to human body. In recent years, the environmental protection industry has been stubborn. What is the method, focus on it!

Industrial waste gas treatment cold doubt method:

According to condensation desuperheating, when the temperature is lower than the condensation point of harmful substances, the harmful substances in the vapor state are transformed into liquid state, obtained from the air, and then cleaned. Advantages: stable operation, efficient cleaning. Disadvantages: The investment project is very large, the staff standards for the geographical environment and the operation process are high, and the energy consumption is too large, and the operation cost is high.

Industrial waste gas treatment Incineration treatment:

Using the method of heating and high temperature, the industrial organic waste gas is immediately incinerated and processed to achieve the purpose of waste gas treatment. Advantages: high cleaning efficiency, reaching more than 96%. Disadvantages: There must be a lot of driving force, and a lot of power engineering driving force must be consumed. Rubber waste gas treatment equipment is also easy to convert into NOX under continuous high temperature, resulting in environmental pollution.

Activated carbon filter equipment adsorption method:

The large surface residual energy of the molecular formula level such as porous activated carbon, silicon bath soil, anthracite, etc. is used to adsorb the molecular formula of industrial waste gas to its surface, and then clean it up. Advantages: High efficiency (activated carbon filtration reaches about 98%), can be used all over the place, easy to use, low investment project cost, and relatively low operating cost.

Professional treatment of industrial waste gas of fine particulate matter pollutants

According to the particle size distribution specifications of fine particulate pollutants, the treatment methods of industrial waste gas include four types: semi-dry desulfurization, dry method, filtering and tip discharge. Desulfurization), plastic foam dust collector equipment (dry method), etc. With the improvement of high-efficiency standards for dust removal, electrostatic precipitators have gradually begun to be applied.

The electrostatic precipitator consists of 2 electric stages. After the current intensity is applied between the electrodes, an electric field is induced in the core of the electrodes. Fine particulate pollutants experience an electric field with the organic waste gas, and the objects are covalently collided and positively charged. The dust charged by induction moves to the pole of the dust removal equipment and reaches the pole piece. In this way, the pollutants in the vapor are absorbed on the pole piece, so that the air is cleaned, and the inhalable particles also fall into the silo due to their own weight.
