| abstract |
The utility model discloses a front multi-point and multi-source spraying smoke and dust and SO 3 coordinated removal system, which relates to the technical fields of energy, chemical industry, environmental protection and the like. It includes a multi-phase mixed injection chamber, a primary dust removal chamber, a gas-liquid injection chamber and a final-stage dust removal chamber. The multi-phase mixed injection chamber is provided with multi-layer three-phase mixing nozzles, and the gas-liquid injection chamber is provided with multi-layer gas-liquid mixing nozzles. There are ash hoppers at the bottom of the mixed jetting chamber, primary dusting chamber, gas-liquid jetting chamber and final dusting chamber. Based on the catalytic effect of H 2 O on the reaction between soot and SO 3 in the utility model, a spray chamber is set before each stage of bag-type dust chamber, and the synergistic removal effect of SO 3 and soot is fully utilized. Energy saving, low operating cost and other advantages. |
