The technical scheme includes that the wet air waste heat recovery device comprises an inlet air blower, an air inlet section of the wet air waste heat recovery device, a heat exchange section of the wet air waste heat recovery device, a spraying section of the wet air waste heat recovery device and an exhaust section of the wet air waste heat recovery device. The wet air waste heat recovery equipment air-blower comprises air inlet fan, the section of admitting air is equipped with a wet air intake, and the air intake front end is equipped with the air-blower, the heat transfer section has a plurality of heat exchange tubes, the section of spraying comprises nonrust steel pipe, the exhaust section is direct to be discharged to outdoor through the gas vent, wet air waste heat recovery equipment below is equipped with a comdenstion water discharge port and overflow mouth, in time retrieves the comdenstion water after the humid air condensation.

Foretell humid air waste heat recovery equipment, wherein, the section of admitting air is blown the humid air into in the equipment by the air-blower, forms the condensation water layer after the heat transfer section condensation, low temperature steam in the condensation humid air heats the medium in the heat exchange tube, forms the comdenstion water after the humid steam releases the latent heat, recycle behind overflow mouth and the bottom discharge port outflow equipment, after the humid air releases partial heat behind the water layer, through exhaust section exhaust equipment, open the mouth that sprays when long-term use or equipment stop use, can rinse the heat exchange tube on line, improve heat exchange efficiency.

The wet air waste heat recovery equipment provided by the utility model has the following beneficial effects: 1. the latent heat of low-temperature steam in the wet air can be effectively recovered, and the purposes of waste heat recovery, energy conservation and consumption reduction are achieved; 2. condensed water formed after low-temperature steam in the humid air is condensed can be effectively recovered, so that the purpose of recovering and reusing the condensed water is achieved; 2. Can effectively reduce the discharge amount of wet steam in the wet air and beautify the environment.
