Summary of the invention:
The present invention is exactly to the problems referred to above, and a kind of device and treatment process that utilizes the Heat Treatment mud of boiler smoke discharge is provided.
For realizing above-mentioned purpose; The present invention adopts following technical scheme; It adopts like lower device: the present invention includes boiler; Boiler links to each other with coal conveyer belt device, exhaust smoke processing device respectively, and the flue of its structural feature exhaust smoke processing device links to each other with drying machine with drying machine and through induced draft fan, cyclonic separator respectively, and the side of drying machine links to each other with the mud storage silo; The bottom of drying machine, cyclonic separator links to each other with finished bin through rotary conveyor, and finished bin links to each other with the coal conveyer belt device through worm conveyor.
The present invention adopts following treatment process:
At first the flue gas with the boiler exhaust gas road feeds drying machine, with drying sludge; Tail gas after dry in the mud is to the boiler exhaust gas road, and remaining mud is participated in burning in the back boiler again.
Beneficial effect of the present invention:
The present invention makes full use of the waste heat of heat power plant discharging flue gas, is fully utilized, and the temperature of power plant's smoke evacuation is reduced, and has reached the purpose of energy-conservation, reduction of discharging, environmental protection.
The invention solves the wet sludge treatment problem of the long-term puzzlement in city, and make dried mud powder and the particle that contains certain calorific value after the processing, participate in burning, resource is fully used as low-heat fuel.
