Outlet and the described drying tower of heater are interconnected, and described drying tower sidewall is fixing is communicated with blowing machine, and described energy returns
Being fixed with nozzle and gas channel inside receiving apparatus, described gas channel sidewall is provided with opening, the outlet of described blowing machine
Being interconnected with described nozzle, described nozzle and described gas channel are interconnected, the company of rotation in the middle part of described gas channel sidewall
Being connected to drive link, described drive link is fixed with leaf grating, described drive link end is fixedly connected with electromotor, and described energy returns
Fixing bottom receiving apparatus and be communicated with Water Sproading case, described energy recycle device is by described air circulating umbilical and described air filtration
The entrance of device is interconnected.
Preferably, described air filter includes dust filtering device and Mist filtration device.
Preferably, described air circulating umbilical outer wall is enclosed with heat-insulation layer.
Technique effect of the present utility model and advantage: this has the spray drying case of waste heat recovery structure, passes through blowing machine
Tail gas in drying tower can be extracted out, be then sent in gas channel by nozzle, because the tail gas in drying tower contains
Substantial amounts of superheated vapor, superheated vapor, when nozzle enters gas channel, can produce expansion, during expanding, its enthalpy
Value can decline, and kinetic energy can improve, thus through leaf grating when, can the rotation of band moving blades, leaf grating drives drive link
Rotate, utilize drive link to drive the rotation of generator rotor shafts, can generate electricity, such that it is able to be that whole device supplements electricity
Can, and at superheated vapor after leaf grating, its kinetic energy can decline, and temperature also can decline, thus the part in superheated vapor
Steam can become aqueous water, can flow to carry out in Water Sproading case storing recycling, and the gas of remaining high temperature can pass through air
Circulation pipe enters in air filter, after filtering out steam, enters back in air heating apparatus and heats, thus real
Now recycle.Therefore, this utility model is reasonable in design, by utilizing the multilamellar of waste heat in tail gas in drying tower, improves
The utilization rate of waste heat, the effect of the energy-conserving and environment-protective reached, there is the strongest practicality.
