Abstract

The invention discloses a method and device for drying sludge by utilizing thermal power plant waste heat. The device comprises a furnace, wherein a plate type feed conveying belt and a plate type discharge conveying belt are arranged in a hearth. Multiple layers of middle-layer plate type conveying belts are distributed between the plate type feed conveying belt and the plate type discharge conveying belt from top to bottom. The middle-layer plate type conveying belts divides an internal airflow channel of the hearth into S-shaped airflow channels. Drying air detours and flows in the hearth under the flow distributing effects of the airflow channels along an S-shaped flow track. Sludge falls to the first-layer middle-layer plate type conveying belt from the tail end of the plate type feed conveying belt, then sequentially falls to the plate type discharge conveying belt from the tail end of the first-layer middle-layer plate type conveying belt so that the sludge can move in the hearth along the S-shaped track from top to bottom, and finally the sludge is discharged out through the plate type discharge conveying belt. The device can save considerable high-grade electric energy, achieves drying by using lower-grade flue gas waste heat and has the advantages of being efficient, capable of saving energy, environmentally friendly, high in space utilization rate and facilitating large-scale drying.

The lower sides of described burner hearth 4 is provided with dry wind feedway;Dry wind passes sequentially through from bottom to top Board-like discharging conveyer belt 2-2, middle level board-like conveyer belt 2-3 and board-like charging conveyer belt 2-1, dry wind exists Under their shunting action, the most S-shaped flow trace is circuitous flow in burner hearth 4, finally by Burner hearth 4 top vent is discharged;
When mud is delivered in burner hearth 4 by board-like charging conveyer belt 2-1, mud is by board-like charging transport End with 2-1 tumbles to the board-like middle level conveyer belt of ground floor, then is transported by the board-like middle level of ground floor End of tape tumbles successively to board-like discharging conveyer belt 2-2, makes the most S-shaped track of mud at burner hearth 4 Interior motion, is finally sent by board-like discharging conveyer belt 2-2.
The described mud direction of motion in burner hearth 4 is contrary with dry wind flow direction in burner hearth 4.
The number of plies of described middle level board-like conveyer belt 2-3 is more than two-layer or two-layer, the board-like fortune in middle level of each layer The end of defeated band 2-3 is interlaced with each other.
Between board-like charging conveyer belt 2-1, middle level board-like conveyer belt 2-3 and board-like discharging conveyer belt 2-2, Also have additional hydraulic barrier 3;Hydraulic barrier 3 is interspersed on the medial wall of burner hearth 4.
Described dry wind feedway includes absorbed moisture removing device, heater heated by waste heat;Air is removed by absorption Wet device enters in heater heated by waste heat, then is sent in burner hearth 4 by heater heated by waste heat.
Described burner hearth 4 top vent is provided with exhaust gas processing device 1, is provided with movable rows bottom described burner hearth 4 Slag plate 5.
Described exhaust gas processing device 1 is catalyst filtration layer, the harmful substance in eliminating waste gas.
The wet drying method for sludge of a kind of combination steam power plant UTILIZATION OF VESIDUAL HEAT IN is as follows:
Step one: start dry wind feedway, dry wind is entered in burner hearth 4 by the bottom side of burner hearth 4;
Dry wind passes sequentially through board-like discharging conveyer belt 2-2, middle level board-like conveyer belt 2-3 and plate from bottom to top Formula charging conveyer belt 2-1, dry wind is under their shunting action, and the most S-shaped flow trace exists Circuitous flow in burner hearth 4, is finally expelled to air by burner hearth 4 top vent;
Step 2: start board-like charging conveyer belt 2-1, board-like discharging conveyer belt 2-2 and the board-like transport in middle level Band 2-3, makes them operate;
Mud is placed on board-like charging conveyer belt 2-1, board-like charging conveyer belt 2-1 is delivered to burner hearth 4 Inner top, mud, by the end of board-like charging conveyer belt 2-1, tumbles under gravity to ground floor On the conveyer belt of board-like middle level, then by the board-like middle level conveyer belt of ground floor end continue gradually tumble under On the board-like middle level conveyer belt of a layer, circulate and so forth;Make the most S-shaped track of mud at stove Turning movement in thorax 4, and be gradually dried;This increased periods mud and dry wind are in the burner hearth 4 Time of contact and contact area, make mud be fully dried;
Dried mud after send through board-like discharging conveyer belt 2-2.
The supply process of dry wind feedway described in above-mentioned steps one is as follows:
Outside air is first by vaporizer cool-down dehumidification, then improves temperature by condenser so that it is relative humidity Reduce, then through heater heated by waste heat, utilize remaining heat of flue gas from steam power plant again to heat so that it is relative humidity enters one Step reduces, and is now passed through in burner hearth 4.
The temperature of dry wind described in above-mentioned steps one is 100 DEG C~150 DEG C.
The present invention, relative to prior art, has such advantages as and effect:
The lower sides of burner hearth 4 of the present invention is provided with dry wind feedway;Dry wind depends on from bottom to top Secondary by board-like discharging conveyer belt 2-2, middle level board-like conveyer belt 2-3 with board-like charging conveyer belt 2-1, dry Dry wind is under their shunting action, and the most S-shaped flow trace is circuitous flow in burner hearth 4, Finally discharged by burner hearth 4 top vent;When mud is delivered to burner hearth 4 by board-like charging conveyer belt 2-1 Time interior, mud is tumbled to the board-like middle level conveyer belt of ground floor by the end of board-like charging conveyer belt 2-1, Tumbled successively to board-like discharging conveyer belt 2-2 by the board-like middle level conveyer belt end of ground floor again, make mud certainly Upper and under S-shaped track move in burner hearth 4, finally sent by board-like discharging conveyer belt 2-2.This Bright this structure, not only makes mud add in dry run and dry wind contacting in burner hearth 4 Time and contact area, make mud be more fully dried;And take full advantage of space, reduce Occupation area of equipment.
In order to preferably make dry wind in burner hearth 4 residence time and with mud time of contact, board-like Between charging conveyer belt 2-1, middle level board-like conveyer belt 2-3 and board-like discharging conveyer belt 2-2, also add Hydraulic barrier 3, further increases the baffling effect to dry wind, fully extends dry wind at burner hearth 4 Interior stroke;Further increase the time of staying, make mud be fully contacted with dry wind (hot-air), It is dried more complete.
The mud of the present invention direction of motion in burner hearth 4 and dry wind flow direction in burner hearth 4 On the contrary, i.e. motion between them is antikinesis, in limited space, further enhances mud Rate of drying and drying effect.
Slat conveyer of the present invention (the most board-like charging conveyer belt 2-1, middle level board-like conveyer belt 2-3 and Board-like discharging conveyer belt 2-2) speed can according to operating mode need regulation, increase arrangements for speed regulation;Consider Pollution waste gas can be produced to drying sludge, be provided with exhaust gas cleaner at drying oven top, reduce mud It is dried the negative effect to environment.
Relatively conventional drying mode, technical measure is simple and easy to do.A large amount of high-grade electric energy can be saved, And it is achieved that dry with more low-grade fume afterheat, and energy-efficient, environmental protection, space availability ratio height, The advantage being prone to maximization scale, can be widely applicable for the drying and other treatment of extensive wet mud.
