Кои са често срещаните замърсители, контролирани от система с термичен окислител?

In modern industrial processes, thermal oxidizers are an essential part of the air pollution control system. Thermal oxidizers help remove pollutants from industrial exhaust streams. In the following paragraphs, we will discuss the common pollutants controlled by a термична окислителна система.

1. Volatile Organic Compounds (VOCs)

Volatile Organic Compounds (VOCs) are one of the most common pollutants that thermal oxidizers control. VOCs are carbon-based chemicals that have a high vapor pressure at room temperature. The sources of VOCs include petrochemical plants, paint and coating plants, and printing industries. When the VOCs are released into the atmosphere, they react with nitrogen oxides and sunlight to produce ozone (O3) and smog. The thermal oxidizer system can oxidize the VOCs by raising the temperature in the combustion chamber to a high temperature, which will break down the VOCs into less harmful substances.

2. Hazardous Air Pollutants (HAPs)

Hazardous Air Pollutants (HAPs) are another common group of pollutants that thermal oxidizers control. HAPs are chemicals known to cause cancer, birth defects, and other serious health effects. The sources of HAPs include chemical plants, petroleum refineries, and waste incinerators. The thermal oxidizer system will treat HAPs by oxidizing them at high temperatures, which will transform them into less hazardous chemicals.

3. Nitrogen Oxides (NOx)

Nitrogen Oxides (NOx) are the third most common pollutants that thermal oxidizers control. NOx is a group of highly reactive gases that form when fuels are burned at high temperatures. The sources of NOx include power plants, industrial boilers, and diesel engines. When NOx is released into the atmosphere, it reacts with other compounds and sunlight to form smog and acid rain. The thermal oxidizer system will control NOx by reducing the temperature in the combustion chamber, which will prevent the formation of NOx and convert them into nitrogen and oxygen.

4. Carbon Monoxide (CO)

Carbon Monoxide (CO) is a colorless, odorless gas that is highly toxic to humans and animals. CO is produced when fuels are burned in insufficient oxygen conditions. The sources of CO include power plants, industrial furnaces, and internal combustion engines. The thermal oxidizer system will remove CO by oxidizing it at high temperatures, which will transform it into carbon dioxide (CO2).

5. Particulate Matter (PM)

Particulate matter (PM) is a complex mixture of tiny particles that can cause serious health effects when inhaled. The sources of PM include power plants, industrial boilers, and diesel engines. The thermal oxidizer system will control PM by passing the exhaust stream through a series of filters, which will remove the particles before they are released into the atmosphere.

6. Sulfur Dioxide (SO2)

Sulfur dioxide (SO2) is a gas produced when fuels containing sulfur are burned. SO2 is a major contributor to acid rain, which can cause damage to crops, forests, and buildings. The sources of SO2 include power plants, smelters, and diesel engines. The thermal oxidizer system will control SO2 by oxidizing it into sulfur trioxide (SO3) and then into sulfuric acid (H2SO4), which can be removed from the exhaust stream using scrubbers.

7. Hazardous Organic Air Pollutants (HAPs)

Hazardous Organic Air Pollutants (HAPs) are a group of organic chemicals known to cause serious health effects. The sources of HAPs include chemical plants, refineries, and waste incinerators. The thermal oxidizer system will remove HAPs by oxidizing them at high temperatures, which will transform them into less harmful substances.

8. Heavy Metals

Heavy metals are a group of metallic elements that can cause serious health effects when they are inhaled. The sources of heavy metals include power plants, smelters, and waste incinerators. The thermal oxidizer system will control heavy metals by capturing them using filters or scrubbers.
