How to treat waste gas in biomass boiler

2021-08-04

Biomass boilers have many advantages, but there are also disadvantages. Due to the different characteristics of biomass fuels and fossil fuels, the fuel mechanism, reaction speed and fuel product composition of biomass fuels are quite different from those of fossil fuels. Biomass fuel has a high moisture content, the fuel requires a higher drying temperature and a longer drying time, the generated flue gas volume is large, and the flue gas loss is high.

1. Install the boiler exhaust gas treatment purification tower. The exhaust gas enters the purification tower tangentially from the air inlet below the exhaust gas treatment tower body. Under the power of the ventilator, it quickly fills the air inlet section space, and then evenly rises through the flow equalization section. , After the first-level and second-level filler absorption section, the purification effect can be effectively achieved.

2. Adopt clean combustion technology, develop high-efficiency combustion technology, and use clean burners to reduce the pollution of nitrogen oxides to the air.

3. Install desulfurization equipment. We are desulfurizing biomass boiler exhaust gas, removing harmful gases in biomass boiler exhaust gas, preventing acid rain and preventing air pollution.

4. Increase the altitude of the chimney. According to the survey, every time the height of the chimney rises by one meter, the area of ​​pollution diffusion is correspondingly expanded, thereby diluting the smoke pollution to the atmosphere. Increase the altitude of the chimney to spread pollution. Because the higher the chimney, the larger the pollution area, thereby diluting the smoke pollution to the atmosphere. This method is generally not advocated. We are just one earth and we breathe the same atmosphere. The editor reminds us not to adopt this method as much as possible.

6. Install desulfurization equipment to fix sulfur dioxide. We all studied chemistry in high school, and our chemistry teacher taught us the chemical formula of what sulfur reacts with to form a solid. Sulfur dioxide can form acid rain, which is bad for the atmosphere. In this way, we will prevent the appearance of acid rain. Desulfurization is divided into two categories: wet desulfurization and dry desulfurization.

7. Boiler factories and mines must increase their budget for dust removal equipment. The boiler flue gas contains a large amount of dust, which is collected by a dust collector to prevent secondary pollution to the atmosphere. There are many types of dust collectors, such as bag dust collectors, electric dust collectors, water mill Venturi dust collectors.
