Abstract

The invention provides a wet washing device and a cooling method during flue gas washing, the wet washing device comprises a flue gas washing circulating system and a dehumidification circulating system, the flue gas washing circulating system is used for washing flue gas, the dehumidification circulating system is used for dehumidifying the flue gas, the wet washing device further comprises an inlet spraying system, the inlet spraying system comprises a water tank, a spraying liquid conveying pipeline, a spraying piece and an inlet flue, the water tank is connected with the spraying liquid conveying pipeline, the spraying liquid conveying pipeline is connected with the spraying piece, and the spraying piece extends into the inlet flue for spraying. When the wet washing device is used for washing the flue gas, the flue gas is sprayed to the inlet flue through the inlet spraying system so as to reduce the heat of the flue gas.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to a wet scrubbing device and a cooling method during flue gas scrubbing. Background technique [0002] In the current wet deacidification technology used in waste incineration plants, the original flue gas can only be cooled after entering the scrubber from the inlet flue. Due to the uneven gas flow field and insufficient gas-liquid contact, the high-temperature flue gas enters the scrubber After that, it is difficult to be cooled completely immediately, and there is still a local high temperature area in the lower part of the washing tower; high temperature will reduce the efficiency of the deacidification reaction, and will also reduce the solubility of the absorbent in the absorption liquid to promote salt crystallization. In addition, the lower cylinder of the washing tower generally needs to be lined Insulation materials such as fire-resistant flint or refractory...
