摘要：

PM2.5 refers to fine particles with a diameter of 2.5 mu m or less in the air. With PM2.5 continuously impacting people's lives, researchers are starting to pay more attention on the treatment of flue gas emitted from coal-fired boilers. This paper introduces a treatment device for ejected fine flue gas. The device uses ejectors to effectively remove acid substances and large dust particles contained in flue gas, and uses air dynamic ultrasonic atomizer to eliminate micro dust particles effectively. The overall scheme of the flue gas processing device is designed, the principle and simulation results of the main components of the ejector are studied, and the optimal value of the ejector ratio is determined by experiments. Finally, the efficiency of processing dust and sulfur dioxide in the flue gas is tested during experiments on the industrial worksite. For the gas emissions from domestic small- and medium-sized coal-fired boilers, this device is more efficient and costs less energy.
