Waste gas treatment in the electronics industry: efficient solutions and advanced technologies

With the advancement of science and technology and the acceleration of industrialization, the electronics industry has become one of the important pillars of the global economy. However, the problem of exhaust emissions in the electronics industry has become increasingly prominent and has become a major challenge for environmental protection. Exhaust gas contains a variety of harmful substances, such as volatile organic compounds (VOCs), heavy metals, acid gases, etc., with complex components, which pose a serious threat to the environment and human health. Therefore, the development and adoption of efficient waste gas treatment technology has become an urgent need for the electronics industry.

electronic industry waste gas treatment approach:

Electronic industry waste gasIt has the characteristics of many kinds and complex components. In general, the air volume of exhaust gas is large and the concentration is low. Especially in the semiconductor manufacturing process, in addition to the common volatile organic compounds (VOCs), but also produce some acid gases, alkaline gases and toxic gases, these waste gas components on the environment is particularly serious.

The electronics industry involves more VOCs, mainly photovoltaic manufacturing and electronic component manufacturing. Taking the manufacture of electronic components as an example, electronic components include capacitors, electrical positives, potentiometers, inductors, electronic variable instruments, control components, electronic sensitive components, sensors and printed circuit boards.

In view of the characteristics of electronic industry waste gas,waste gas treatment technologyThe choice is crucial. Depending on the use scenario, there are usually three main technical paths, such as adsorption, combustion, and spray absorption, each of which has its scope of application and characteristics.

high concentration of VOCs exhaust gas:For high-concentration VOCs waste gas, condensation recovery technology or adsorption recovery technology should be preferred to recover valuable organic solvent resources. On this basis, the exhaust gas can be further treated by catalytic combustion or direct combustion technology to ensure that the final emission meets the requirements of environmental protection standards.
Medium and low concentration VOCs exhaust gas:For medium and low concentrations of VOCs waste gas, a combination of "adsorption concentration-regeneration recovery" technology or "adsorption concentration-combustion" technology is usually used. First, the VOCs in the exhaust gas are captured by adsorption materials such as activated carbon, and then the organic matter in the adsorbent is recovered by thermal regeneration, and finally the concentrated exhaust gas is sent to the combustion device for thorough oxidation treatment.
Waste gas containing non-water soluble VOCs:Waste gases containing non-water-soluble VOCs shall not be treated only by water or aqueous solution spray absorption. This kind of waste gas usually needs to be purified by special organic solvent absorption or other physical and chemical methods.
solvent type coating process waste gas:The waste gas generated in the solvent-based coating process is usually pretreated by spray absorption process to remove paint mist and particulate matter. An appropriate subsequent processing technique can then be selected depending on the circumstances.
waterborne coating process waste gas:The waste gas generated by the water-based coating process can be treated by spray absorption process, and the organic matter in the waste gas can be removed by water or aqueous solution spray absorption. In some cases, other techniques can be combined to further improve the purification efficiency.

Exhaust gas treatment in the electronics industry is a complex process, and it is necessary to select the appropriate treatment technology according to the specific composition and concentration of the exhaust gas. Through the use of efficient technology and equipment, not only can significantly reduce the content of harmful substances in the exhaust gas, but also meet strict environmental standards, and promote the sustainable development of the electronics industry.
