System for centralized management of haze in cities

The invention provides a system for centralized management of haze in cities. The system comprises an air outlet pipe, an air discharge hole and related connecting pipes, wherein a haze intake hole iscommunicated with the lower part of an air purification tower through an air inlet, and a water outlet is formed at the bottom of the air purification tower; a sewage treatment tank is in communication with the water outlet through a pipeline, and a reservoir is connected to a liquid inlet through a pipeline; the liquid inlet is connected with a nozzle in the air purification tower; the nozzle isarranged at the upper part of the air purification tower; the air outlet pipe is arranged at the top of the air purification tower and is in communication with the air discharge hole. The system introduces haze contained air through the haze intake hole and processes the air by atomizing water to perform dust removal, acid removal, desulfurization and haze removal, so as to finally purify the air. The system is designed a
