【 摘 要 】

Industrial combustion flue gas contains fine dust, water vapor, in order to remove micro dust, and to recover water vapor at the same time. we have put forward a research on the technology of recovering water vapor and dust removal by using a cyclone separator for the first time. By studying the pressure drop, the separation efficiency and the efficiency of recovering condensed water of the flue gas, we can get the optimum technological parameters for the actual working conditions. The results show that the pressure drop increases with the increase of inlet velocity and temperature, and the rate of increase is increasing. When under the same cooling water flow rate, the dust separation efficiency increases first and then decrease with the inlet velocity increase. When the inlet velocity is near the 50 m3/h, the separation efficiency reaches the maximum, 96%. The amount of vapor recovery increases with the increase of cooling medium flow rate in 15 minutes. When at the same cooling medium flow rate, the recovery increases first and then decrease with the inlet velocity increase, and reaches the maximum when the inlet velocity is 60-80 m3/h.
