Thermal power plant

The application of filter bags in pollution control in power plants can involve the following aspects

1.Flue Gas Purification: Power plant flue gases contain various pollutants such as dust, sulfides, nitrogen oxides, etc. Filter bags are widely used in the flue gas purification systems of power plants. By passing the flue gas through cloth bags, solid particles are captured using the pores and surface of the filter material, thus purifying the flue gas and reducing the concentration of emitted pollutants

2.Dust Removal from Coal-Fired Boilers: Coal combustion in boilers produces a large amount of dust and particulate matter in the flue gas. By installing filter bag systems, these particulate matters can be captured as the flue gas passes through, ensuring that the emitted flue gas meets environmental standards.

3.Gas Treatment: Apart from coal-fired boilers, other processes in power plants may also generate exhaust gases containing harmful substances. Filter bags can be used to capture particulate matter and pollutants in these exhaust gases, purifying them and protecting the environment.

4.Desulfurization and Denitrification: Filter bags can also be part of desulfurization and denitrification systems. In these systems, the flue gas passes through specific treatment units such as spray towers or absorption towers, and then undergoes further purification through filter bags to remove sulfur compounds and nitrogen oxides, among other harmful substances.

5.Recycling: Solid waste collected by filter bags in power plants, such as dust and particulate matter, can be recycled in some cases. For example, some metal particles can be reclaimed, while other materials can be processed into landfill or other solid waste applications.

The application of filter bags in power plants helps to protect the environment, reduce pollutant emissions, and is typically a necessary means to comply with regulations and standards.
