[0002] In the production of chemical dyes, the dye slurry is spray-dried in the drying spray tower. The hot air used to dry the slurry flows out from the bottom of the tower. The hot air carries a large amount of dry dye powder. Generally, a cyclone separator is used to remove dust, The bag filter then uses a water film filter to remove dust and then empty it. This kind of dust treatment method, firstly, the condensed liquid cannot be recycled, and it takes a lot of energy to deal with it; secondly, the hot air carries a lot of heat and has not been effectively used. , resulting in a waste of energy. Once again, the waste gas from chemical production should be recycled as much as possible after being purified to meet the standard to reduce the total amount of waste gas emissions.

The invention relates to the technical field of waste gas purification and recycling and relates to a spraying tower waste gas purification and recycling device. The bottom of a chemical spraying tower is connected with a cyclone dust collection device; a waste heat recycling device is arranged between the cyclone dust collection device and a cloth bag dust collection device; the top of the wasteheat recycling device is connected with a cloth bag dust collector; the air outlet of the cloth bag dust collector is connected with one end of a draft fan; the other end of the draft fan is connectedwith a washing condensation absorption tower and a secondary UV (Ultraviolet) electric field purifier in sequence; the secondary UV electric field purifier is connected with a waste gas discharge tube and a recycling pipeline; and the recycling pipeline penetrates through the waste heat recycling device and a heater in sequence and is connected with the top of the chemical spraying tower. Compared with the prior art, the device has the beneficial effects that a backflow air flow has a high temperature, the air flow heating time and energy can be saved, moisture generated in the purification process is discharged into a material stirrer from a condensation accumulated liquid backflow tube, and thus accumulated liquid condensation, waste gas purification and cyclic utilization of production waste gases and waste heat can be achieved.
