Local Scrubber Exhaust Gas Treatment System Việt Nam

The Local Scrubber exhaust gas treatment system is a widely used tail gas treatment equipment in industries such as solar photovoltaics, semiconductors, and microelectronics. It is primarily used to treat the excessive hazardous gases generated in these industries, including but not limited to SiH4, SiH2Cl2, PH3, B2H6, TEOS, H2, CO, NF3, SF6, C2F6, WF6, NH3, N2O, and so on. If not properly treated, these gases may pose hazards to the environment and human health.

The Local Scrubber exhaust gas treatment system effectively reduces the emissions of these harmful gases through specific treatment steps and methods such as combustion, cooling, and water scrubbing. Its working principle may involve guiding the exhaust gas to a combustion chamber for combustion, converting organic matter and other combustible substances into harmless substances. Then, it passes through a cooler for cooling to facilitate subsequent water scrubbing treatment. Finally, the exhaust gas enters a water scrubbing tower where harmful substances are adsorbed by water vapor and mixed with water, thus being effectively removed.

The purpose of this system is to prevent unexpected gas leaks, local accumulation, or mutual reactions during the exhaust process, thereby averting potential issues such as duct blockage, pipeline corrosion, leaks, and fire explosions. The treated gas is then further connected to other treatment systems for secondary disposal, reducing the load on subsequent treatment systems and meeting the requirements of air pollution control and emission standards in specific industries.

Overall, the Local Scrubber exhaust gas treatment system is an efficient and environmentally friendly tail gas treatment solution that is crucial for ensuring production safety, protecting the environment, and safeguarding human health.

The Local Scrubber exhaust gas treatment system operates based on a combination of chemical and physical principles to effectively treat harmful gases generated in various industrial processes. Its application scenarios are diverse, particularly in industries where the emission of hazardous gases is inevitable, such as solar photovoltaics, semiconductors, and microelectronics.

The principle behind the Local Scrubber lies in its ability to capture and neutralize harmful gases through a series of treatment steps. Initially, the exhaust gas is channeled into the scrubber unit, where it encounters a scrubbing solution, usually a liquid mixture designed to react with the specific gases present. As the gas passes through the scrubbing solution, harmful components are either absorbed or chemically reacted with the solution, converting them into safer substances or removing them from the gas stream.

The choice of scrubbing solution is crucial, as it must be tailored to effectively treat the specific gases emitted by the industry. For instance, in the solar photovoltaics and semiconductor industries, gases like SiH4, SiH2Cl2, PH3, and B2H6 are commonly emitted. The scrubbing solution is formulated to react with these gases, neutralizing their harmful effects.

In addition to chemical neutralization, the Local Scrubber may also utilize physical processes such as cooling and filtering to further purify the exhaust gas. Cooling helps to condense and remove certain components, while filters trap particulate matter, ensuring that only clean gas is released into the atmosphere.

The application scenarios of the Local Scrubber are vast. It is particularly suitable for industries that involve high-temperature processes, the use of toxic chemicals, or the production of harmful by-products. Solar photovoltaic manufacturing, for instance, often involves the use of hazardous gases during the production of solar cells. The Local Scrubber effectively treats these gases, ensuring that they do not escape into the environment.

Semiconductor and microelectronics manufacturing are also key application areas for the Local Scrubber. These industries often emit gases such as NF3, SF6, and other fluorinated compounds, which are both harmful to the environment and potentially corrosive to equipment. The scrubber effectively removes these gases, protecting both workers and the surrounding environment.

In summary, the Local Scrubber exhaust gas treatment system leverages both chemical and physical principles to neutralize and remove harmful gases from industrial exhaust streams. Its diverse application scenarios in industries like solar photovoltaics, semiconductors, and microelectronics demonstrate its importance in ensuring environmental safety and protecting human health.
