Abstract
The invention discloses a rapid mechanical type sludge dewatering system which can reduce the moisture content of sludge to the level meeting the requirements within a shorter time. The system comprises a crushing and stirring system, a conveying system and a belt-type pressing filter, wherein one end of the conveying system is fixed below the discharge port of the crushing and stirring system; and the other end of the conveying system is fixed on a rack of the belt-type pressing filter. The system is characterized in that the crushing and stirring system comprises a stirring device and a feeding, crushing and mixing device; a modifier feeding device and a sludge feeding device are fixed above the feeding, crushing and mixing device; the stirring device is fixed below the feeding, crushing and mixing device; and an accelerant feeding device is arranged on the stirring device. According to the system, sludge containing more than 80% of water is rapidly and continuously squeezed and dewatered on the belt-type pressing filter after being modified, so that the moisture content of the sludge is greatly reduced, that is, the water content of the dewatered sludge is less than 50%; the difficulty in storing, transporting and storing the sludge are solved; and the sludge treatment cost is lowered.
Description
Technical field
The present invention relates to environmental protection equipment, especially relate to a kind of can within a short period of time, the moisture percentage in sewage sludge after dehydration is down to satisfactory sludge dewatering system.
Background technology
The whole nation sewage work wet mud of annual discharging is more than 5,000,000 tons.A large amount of mud not stabilized, harmless treatment have become the heavy burden of sewage work, again environment have been produced secondary pollution simultaneously.For the transportation that facilitates mud, deposit and processing and utilization, must carry out further drying to the mud after preliminary hydro-extraction, with reduce mud volume and transport management expense, and create conditions for next step recycling (as doing fuel, building materials etc.).Therefore the processed of mud is very necessary.
Domesticly start late for sludge dewatering gordian technique and research, most achievements in research rest on laboratory level, be short of relative with the ability of industrialization combination.([1] is prosperous refined for Lv Bin etc., Wang Hongyu, Yang Xiaojun. dewatering performance of sludge conditioning technology progress [J]. Shanxi architecture, 2009,35 (9): 180-182) adopt microwave technology to carry out the pre-treatment of dewatered sludge, obviously reduce moisture percentage in sewage sludge, but be not suitable for carrying out Industry Promotion from economic angle, lack the recycling sludge utilization that sludge treatment facility that, conditioning concentrated with mud, mechanical dehydration be integrated and technology reach all kinds of forms that are connected with it.([2] Xu Wenyi such as Xu Wenyi, Li Xing, the Southern Army. impact and the membrane fouling detection technique applied research [J] of polymeric flocculant characteristic on sludge conditioning and dehydrating effect. Treatment of Industrial Water, 2009, 21 (10): 26-29) reported that the polymeric flocculant characteristic is used the impact of sludge conditioning and dehydrating effect and membrane fouling detection technique and ground, beautiful young light plum etc. ([3] beautiful young light plum etc. the impact research [J] of Inorganic Conditioner on Sludge Reuse as Building Materials. Chinese water supply and drainage, 2006, 22 (13): 82-85) reported the impact research of Inorganic Conditioner on Sludge Reuse as Building Materials, their rational Application low-molecular inorganic amendment can reach the requirement of sludge treatment technique, can effectively reduce water ratio and the resistivity thereof of sludge cake, improve the dewatering efficiency of mud, more be conducive to subsequent disposal and the building materials utilization of mud.But only inquired into the use of amendment to the impact of excess sludge dewatering.([4] Zhao Hong such as Zhao Hong, open and sharpen a man of virtue and ability. the application [J] of van-type plate-and-frame filter press in sludge dewatering. Chinese water supply and drainage, 2007,33 (7): 96-99) reported the application of van-type plate-and-frame filter press in sludge dewatering, but the design calculation, type selecting and the application notice that only plate-and-frame filter press are applied in the sludge dewatering engineering are analyzed discussion, cause research to lack systematicness, with the requirement of actual industrial application, certain distance is arranged still.
Existing mud dewatering method has nature mummification, mechanical dehydration and sludge drying etc.Nature drying bed simple structure, floor space people, open type, unhygienic, easily form secondary pollution.Sludge drying, energy consumption is large, invests high.
At present, extensively adopting the mechanical dehydration method both at home and abroad, is the material of difficult dehydration due to mud, directly carries out mechanical dehydration, dehydration difficulty lacks the recycling sludge utilization that the sludge treatment facility that is integrated with sludge modification, mechanical dehydration and technology reach all kinds of forms that are connected with it.Currently used dewatering machine is mainly whizzer, plate-and-frame filter press, belt filter press and vacuum filter etc.The centrifuge noise is large, energy consumption is high, and manufacturing and running cost are all quite high, very uneconomical.The belt filter press floor space is large, operation running environment is relatively poor.The vacuum filter auxiliary facility is many, complex procedures and working cost high.
Summary of the invention
The object of the invention is to adopt the mechanical dehydration machine directly to carry out sludge dewatering to have the problems such as dewatering is poor, a kind of mud rapid dewatering system that is integrated with sludge modification, mechanical dehydration is provided for existing.Can significantly reduce moisture percentage in sewage sludge, the volume of reduce mud solves mud transportation and the difficulty that stores, and reduces the sludge treatment expense.
the present invention is achieved in that a kind of mechanical type mud rapid dewatering system, it is by broken stirring system, delivery system and belt filter press form, one end of described delivery system is fixed on the below of described broken stirring system discharge port, its the other end is fixed on the frame of described belt filter press, it is characterized in that: described broken stirring system comprises whipping appts and charging breaking mixing apparatus, be fixed with properties-correcting agent adding set and mud adding set above described charging breaking mixing apparatus, its below is fixed with described whipping appts, be provided with the promotor adding set on described whipping appts.
On the frame of described belt filter press, delivery system below be fixed with lying device.
Described promotor adding set comprises storage tank and volume pump.
The present invention compared with prior art has following advantage:
1. this system carries out continuous press dewatering fast after moisture mud more than 80% is passed through modification on belt filter press, significantly reduce moisture percentage in sewage sludge, make sludge moisture content after dehydration below 50%, solve sludge dewatering, transportation and a difficult problem that stores, reduction sludge treatment expense.
2. be provided with lying device on the frame of belt filter press, mud is distributed to rapidly on the conveying belt of belt filter press equably, improve the squeezing effect of pressure filter, extend the work-ing life of pressure filter conveying belt.
