[0023] Traditional spray deodorization equipment mainly mixes the spray liquid with pollutants in the exhaust gas through the spray system, so that the pollutants are absorbed into water or chemical agents to achieve deodorization and purification of the exhaust gas.

The small amount of deposited water mist is discharged or reused through the drain port 11. Under the action of the atomizing nozzle 6, the atomized particles of the deodorant are very small. The extremely small atomized particle size can be more fully mixed with the pollutants in the waste gas to improve the treatment efficiency, which solves the problem of loss of purification ability due to saturation of pollutant concentration in the spray liquid. At the same time, under the action of the air circulation structure, the atomized deodorant can be fully mixed with the pollutants to improve the purification efficiency.
