Generally, the flue gas treatment equipment used in waste incineration plants is divided into two categories: dust removal equipment and acid gas removal equipment. Now, with the improvement of people's requirements for environmental quality, most waste incineration plants have added activated carbon adsorption heavy metal equipment to the flue gas treatment process.

[0003] However, when the traditional injection device uses activated carbon powder to adsorb and purify the flue gas in the flue, since the powder is driven by a fan to be injected into the flue, the amount of fly ash and activated carbon injected into the flue is not easy to control and is not uniform. The concentration of adsorption powder in one area is too high, while the concentration of adsorption powder in another area is too low, which will lead to uneven adsorption effect and reduce the overall removal efficiency. The pollutant concentrations in different areas vary greatly, which may cause fluctuations in the concentration of flue gas emissions and fail to meet the emission standards. In view of the above problems, a fly ash and activated carbon mixed injection device is proposed to solve them. Utility Model Content
