Compared with prior art, the beneficial effects of the utility model are:
(1) drying shaping apparatus will wet mud drying and moulding is disposable finishes, and facility investment is saved along with the sludge drying degree is more and more littler in the drying machine space;
(2) utilize the low-grade steam turbine steam that has done work in the power plant that mud is carried out drying, fully save energy;
(3) mud is made the particulate state shaped fuel, helped further grinding and burning;
(4) with the calorific value that can make full use of behind the mud granule turning sludge into fuel in the mud, sludge drying is handled the back volume and is subtracted appearance more than 90%, has important use for the extremely urgent city sewage and sludge handling problem of solution China and is worth.

Embodiment
With reference to the accompanying drawings, below in conjunction with embodiment the utility model is described in detail.
Provide a kind of spiral and rotary type sludge drying shaping apparatus to be used for wet sludge treatment in the present embodiment, its structure as shown in Figure 1.
The hollow hot box 2 of two connection transmission rigs is installed in this spiral and rotary type sludge drying shaping apparatus inside, and some hollow wedge shape blades 6 are set on the hollow hot box 2, and its inside communicates.The two ends of hollow hot box 2 connect the thermal barrier import respectively, pass housing by hollow hot box 2 middle parts and draw heating medium outlet; Wedge shape blade 6 tilts to be installed on the hollow hot box 2, and vergence direction makes the mud material to move to the discharging direction under wedge shape blade 6 promotes, and can certainly adopt the blade of propeller type blade or other shapes.Shaper housing top is a loam cake 3, and loam cake 3 one ends are established a wet stock import, and a products export is established in housing the other end bottom.Blast inlet that feeds dry air and the exhaust outlet of discharging humid gas also are set on the housing.Chuck 5 is set on the housing, steam inlet and condensation-water drain are set on the chuck 5.The inboard of chuck 5 forms and two W type cell bodies 1 that hollow hot box 2 adapts.
In the present embodiment, transmission rig comprises swivel joint 9, sprocket wheel 10, speed regulation device 8, gear 7, bearing and stuffing box 4, and swivel joint 9 is connected with the motor equal power device.
The operation scheme of spiral and rotary type sludge drying shaping apparatus is as follows: the saturation steam after the acting of employing steam turbine is as heating thermal source, pressure 0.4～0.8MPa, 175 ℃ of temperature.From the saturation steam of boiler from steam inlet enter housing chuck 5, enter hollow hot box 2 and wedge blade 6 from the thermal barrier import, fuselage, hollow hot box 2 and wedge shape blade 6 are heated simultaneously, in the mode of conduction heating mud is carried out heat drying.The wet mud that is dried is sent into drying machine quantitatively continuously by the wet stock import, after mud enters fuselage, rotation by wedge blade 6 makes the mud upset, stirs, bring in constant renewal in the heating interface, fully contact with wedge blade 6 with heated fuselage, fully heated, made the contained surface-moisture evaporation of mud.Simultaneously, mud is carried to the products export direction with the rotation of blades axes, continues to stir in conveying, makes the moisture that oozes out in the mud continue evaporation.At last, the mud of uniform drying is discharged by products export.In this process, a small amount of boiler tail flue gas is introduced drying shaping apparatus, the water vapor that constantly produces in the drying sludge process is taken away.Flue gas enters from blast inlet, discharges from exhaust outlet.After the saturation steam heat exchange condensation, by condensation-water drain discharge carrying out reuse.
The utilization of equipment in the present embodiment in mud shaped fuel burning process is as follows:
With treatment capacity is that 300 tons/day mud shaped fuel burning project is an example: after 300 tons of/day primary sludges (water ratio 85%) are transported to sludge incineration factory, be stacked at airtight primary sludge and stack warehouse.Arrive the drying sludge factory building by sludge pump and pipe-line transportation.Mud adopts 2 spiral and rotary type sludge drying shaping apparatus to carry out drying, and the wet mud handling capacity of every drying machine is 150 tons/day.Drying sludge becomes the grain forming fuel of water ratio 30%, granularity 1～5mm.Dried mud is delivered to the dewatered sludge storehouse by belt.Mud in the dewatered sludge storehouse mixes by original coal conveyer belt with the coal of indoor coal storage yard sends into the stokehold coal bunker.Propellant combination in the coal bunker of stokehold can directly be sent in the circulating fluidized bed burning or be admitted to the original coal pulverizer of power plant, enters coal-powder boiler by coal burner and burns.
At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged, and comprises that drying source can adopt thermal oil or high temperature air or flue gas.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
