Background

The quenching tower mainly has the functions of cooling the incineration flue gas to be within 200 ℃ within 2s and deacidifying, and is equipment for preventing the rear-end flue gas from condensing. The quenching tower does not introduce too much water, so the SDA (rotating spray drying) deacidification tower belongs to a semi-wet deacidification method. In actual production, the cheap alkaline material stone is often adopted and is prepared into lime milk to be sprayed into a quench tower, and in order to realize rapid evaporation and uniform distribution of the lime milk, the lime milk is required to be uniformly sprayed into the tower to keep the same with the airflow direction in order to contact with acid gas.

The traditional lime milk spray gun adopts a spray gun positioned at the central position of the upper part of a quench tower, and the spray gun device adopts a stone milk and compressed air double-fluid. However, in order to realize a larger amount of spraying, the lime milk must be atomized farther, the sprayed umbrella-shaped area is larger, a plurality of spray heads are adopted, when the lime milk flies farther away from the center, the kinetic energy is lower, the lime milk is difficult to resist the upward acting force of water vapor at the bottom, so that the wall sticking phenomenon is generated, after the wall sticking effect is accumulated to a certain degree, the tower wall becomes thicker, the gas channel becomes narrower, the lime milk is easy to splash onto the wall when the lime milk is not dried to dryness and is left along the wall, and the wet bottom is caused.
