With the increasing awareness of environmental protection, people are paying more and more attention to the emission problem of coal-fired boilers. As an important supporting equipment for coal-fired boilers, dust collectors play a crucial role in reducing smoke and dust emissions and improving air quality. This article will introduce several common dust collectors suitable for small coal-fired boilers to help readers make the right choices.
- Wet electrostatic precipitator
Wet electrostatic precipitator is a common dust removal equipment with advantages such as high dust removal efficiency, wide applicability, and stable operation. Its working principle is to charge the dust particles through the action of an electric field, and to use water film wet washing for dust removal. Wet electrostatic precipitators can not only effectively remove dust, but also simultaneously remove harmful substances such as sulfur and nitrogen from pollutants.
- Bag filter
Bag filter is a common mechanical filtration equipment that achieves dust removal effect relatively simply by passing smoke through the filter bag and utilizing physical action. Due to its simple structure, high dust removal efficiency, and wide adaptability, bag filters have been widely used in small coal-fired boilers. However, it should be noted that bag filters need to be cleaned regularly to ensure their dust removal efficiency.
- Electrostatic precipitator
An electrostatic precipitator is a device that uses electric field force to concentrate and separate particles. It charges the dust particles through the action of a high-voltage electric field, and then forms an electric field on the conductor plate, causing the dust particles to be subjected to the action of the electric field force, ultimately achieving the dust removal effect. The electrostatic precipitator has the characteristics of high dust removal efficiency, wide adaptability, and stable operation. It is an ideal dust removal equipment for small coal-fired boilers.
- Induced draft dust collector
The induced draft dust collector is a device that further pressurizes the flue gas through a fan and removes dust through a rotating exhaust fan. Its characteristics are significant dust removal effect, high reliability, and wide applicability. The induced draft dust collector is suitable for the flue gas purification of small coal-fired boilers and can effectively remove particulate matter in the flue gas.
