Technical field
The utility model belongs to field of sludge treatment, is specifically related to a kind of sludge dewatering drying forming system.
Background technology
Current sludge drying dewatering type mainly contains following several:
1. centrifuge dehydration: the moisture in mud is thrown away by centrifugal force, but due to the mud of mud, water degree of adhesion high, moisture taken off to 60% and even once difficulty especially by centrifugal force, and energy expenditure is large.
2. press dewatering: sludge slurry is put into canvas bag and binds, is squeezed the water out by pressing machine squeezing, but this kind of mode energy expenditure is large, and the slow water rem oval of pressing machine operational process is low.
3. add lime mixture to dewater: its principle utilized is the water-absorbent of lime, because lime itself can absorb water, can react, removed by moisture with the moisture in mud.But this mode can cause sludge activity to disappear, and the mud after mummification is useless; And, follow-up very difficult when processing the mixture of the mud of these mummification and lime; In addition, because needs use lime in a large number, make this kind of mode cost high.

For the problems referred to above, it is good that the utility model aims to provide mummification dehydrating effect, and water rem oval is high, the sludge dewatering drying forming system that energy expenditure is little.
The technical scheme that the utility model is dealt with problems is: a kind of sludge dewatering drying forming system, comprise A heating tube, air pump, the diffusion column that pipeline and top are opened wide, side, diffusion column lower end is provided with discharge port, diffusion column inner chamber bottom is provided with slope mud can being guided into discharge port be connected with discharge port, diffusion column intracavity bottom is provided with the nozzle ducted gas and mud can spurted into radially in diffusion column, mud is that particulate state is attached to diffusion column inwall, jet exit upward, nozzle inlet end connects air pump by pipeline, A heating tube is provided with between air pump and nozzle,
Pipeline upper bifurcation between A heating tube and nozzle is connected with sludge pump, and sludge pump extracts mud input channel from sludge sump.
Further, the check valve preventing gas backstreaming is provided with between described A heating tube and tapping point.
For preventing in equipment running process, the heat losses of diffusion column is too fast, and the sidewall of described diffusion column is provided with heating and thermal insulation layer, to make mud can as early as possible by hot air dries.
The temperature and operational throughput that add warm air effectively can be regulated for making whole system, this system also comprises warm air reserve tank and B heating tube, the exit end of B heating tube is connected with the import of warm air reserve tank, and the exit end of warm air reserve tank is connected by pipeline with air pump inlet end; Stopping valve and throttling valve is provided with successively between air pump and A heating tube.
For the safety of securing system, the outlet side of described air pump is parallel with the surplus valve to system overload protection.
Further, for making entered air purer, the inlet end of described A heating tube and B heating tube is provided with air filter.
Preferably, be provided with rotary conveyor below described discharge port, the output terminal of rotary conveyor is provided with can, by the pressure roller of the mud compression moulding after dehydration, be convenient to after compression moulding store transport.
The operational process of this system is: air enters from B heating tube under the effect of air pump, in B heating tube, elementary heating is carried out to air, warm air enters warm air reserve tank afterwards, approach air pump and each valve arrive A heating tube, again air is heated in A heating tube, and through Cemented filling to nozzle place;
Meanwhile, sludge pump extracts mud from sludge sump and is delivered to nozzle, and sludge slurry is sprayed into diffusion column through nozzle by the warm air of compression radially, and the mud through nozzle ejection is particulate state, be attached to diffusion column inwall, warm air fully diffuses to whole diffusion column space.Moisture is separated with sludge slurry and is discharged into air from diffusion column top by warm air, is sunk down into the slope of diffusion column bottom, finally export rotary conveyor to by discharge port by the mud of drying due to deadweight.Mud is delivered to its afterbody by rotary conveyor, is rolled to by mud shaping by pressure roller.
In this system, the effect of major parts is as follows:
Warm air reserve tank: for store heat air, so as by control its discharge quantity of hot air number control warm air flow in the duct.
Diffusion column: the place that mud is dried by warm air, its heating and thermal insulation layer can keep the temperature in diffusion column in constant scope.
Nozzle: for mud and warm air are sprayed into diffusion column is tiny particulate state from the mud of nozzle ejection.
A heating tube and B heating tube: air is heated.When elementary heating and secondary heating, the temperature of temperature needed for sludge drying dehydration of heating sets, the object of setting two-step heating is to regulate air themperature in operational process, and secondary heating can be opened according to practical situation or close.
Unusual effect of the present utility model is:
1., owing to being provided with nozzle arrangements, after the granular mud of nozzle ejection is attached to diffusion column inwall, warm air and mud fully contact and contact area improves greatly, and drying efficiency comparatively traditional way significantly improves.Because mud is fine particle, fully expose, it is more thorough that warm air takes away moisture, and dehydrating effect is better.Be proven, the sludge moisture content after the dehydration of this system can to less than 50%.
2. Multi-stage heating pipe, warm air reserve tank and various valve be arranged so that can according to the situation of actual sludge moisture content to hot air flowrate in system operation, hot air temperature regulates, and then can control the ratio that dewaters of mud.Avoid unnecessary energy loss, and dewater by the mode that air is dried, energy expenditure is less.
