    Abstract
  • Based on the principles and advantages of jet bubbling reactor and cyclone separator, a novel type of bubbling tower, cyclone-jet bubbling tower, was designed aiming at the disadvantages of traditional bubbling tower which could not be applied to the flue gas contained large dust content. The distribution of gas phase, the separation property of gas-solid and the efficiency of demisting were analyzed by computational fluid dynamics (CFD) technology. The design integral equation of demisting ring was obtained according to the principle of force balance. The results showed that the uniform distribution of flue gas in the entrance cabin area and the separation of gas-solid at the external tower were achieved by the structure of volute cut-in entrance. The removal efficiency of 5-100 μm and 1-10 μm size dust were 99.43% and 53.70%, respectively. The demisting efficiency was improved from 98.39% to 99.08% by the structure of demisting ring. And the critical particle size of droplet was decreased from 0.047 mm to 0.021 mm. Under the condition of the critical droplet diameter, the demisting efficiency of the swirl plate demister with the demisting ring was 96.20%.
