Description
Technical field
The utility model relates to a kind of device for dehydrating sladge waste, particularly a kind of high mass dryness fraction dehydration equipment of high water content sludge.
Background technology
As everyone knows, the finished product water ratio that the belt dehydration obtains is generally greater than 75%, and its dewatering efficiency is lower, depends on gravity dehydration to a great extent.Slip through after the flocculation treatment at first will carry out gravity dehydration.When filtering beginning, filtrate only need overcome the resistance of filtration medium, the filtering rate of this moment is very fast, increase along with filtration time, the wadding piece sinks, the particle gap dwindles, pack density increases, filtering rate slows down, particularly mud is easy to form the comparatively fine and close filtering layer of one deck on the strainer surface in the gravity dehydration process, causes filtering rate to be reduced to zero very soon.Free water is trapped in the middle of the particle or separates out the slip surface and formed " pond " phenomenon like this.At this moment the gravity dehydration effect to be improved, except the enhanced flocculation effect, importantly the strainer mesh will be dredged.
Discovering that vibration can make in the slip solid particulate leave filtering net surface and move upward, is to solve " pond " problem one of method preferably.Adopt the vibration thickening that mud is carried out gravity dehydration.Mud with flow into vibration thickening band after flocculation agent mixes on, under the effect of vibration dehydration power, mud dewaters on one side, operation forward on one side, because oscillating action, make in the slip solid particulate leave filtering net surface and move upward, played the effect of mediation strainer mesh, namely improved mud gravity dehydration efficient.
Under the effect than strong vibration, solid particulate leaves filtering net surface and moves upward in the slip, has played the effect of mediation strainer mesh, and gravity dehydration is effective, and namely treatment capacity is relatively large, but water only depends on the vibration squeeze force to remove in the born of the same parents.
Osmosis belt filtering and dewatering process is: at first fall on the gravity dehydration band of belt filter press through flocculation mud, and then mud behind gravity dehydration enter into press dewatering and partly carry out press dewatering, mud behind the press dewatering enters the electroosmotic dewatering section again, under the effect of electrical forces with born of the same parents in water discharge, become filter cake shape through the belt press dewatering.
From above-mentioned introduction as can be seen, the characteristics of this scheme are water in the born of the same parents can be discharged, and are conducive to press dewatering, and this structure is though water has been released in the born of the same parents, because shorter filter cake moisture content of press dewatering time is difficult to drop to very low.
The dehydration of screw press formula utilizes gravity and screw extrusion finally to realize sludge dewatering.The slip of flocculation is sent into a diameter in the screw conveying structure that increases gradually, and screw rod is the jogging speed rotation in the screen cloth of a round tube type, and slip is extruded dehydration and is transported forward simultaneously in the spiral that pressure increases gradually.Material stands the pressure dehydration of long period in the screw extrusion filter.The slip that enters at screw shaft one end is along with screw shaft slowly becomes more and more drier in pressing to the process of the other end.The dehydration of screw press formula can only be carried out the preliminary hydro-extraction processing, if increase the time of screw extrusion, the treatment capacity in the unit time is diminished, and output is lower.
In sum, traditional belt squeezing sludge dewatering, filter cake moisture content after the dehydration is very high (75.0%～80.0%) still, its reason is that a lot of water leave the mud intramolecule in, be referred to as water in the born of the same parents, be not released, adopt traditional sludge dewatering method to be difficult to water in this part born of the same parents is discharged; And the electroosmotic dewatering method, mud is under the effect of electrical forces, and water will be easy to be pierced flow out in the born of the same parents.Though adopt the osmosis method very easily water in the born of the same parents to be discharged, the mud very high to the initial aqueous rate (water ratio is 99.2%～95.0%) directly adopts the osmosis method, obviously is uneconomic.
In order to solve the above-mentioned technical problem that prior art exists, the special the utility model that proposes.
Summary of the invention
The utility model provides a kind of spiral to concentrate belt osmosis vibration squeezing integration apparatus for solving the technical problem that exists in the known technology, this equipment is at high water content sludge (water ratio is 99.2%～95.0%), by integrated spiral concentrate, technology such as gravity concentrates, belt squeezing, electroosmotic dewatering and vibration squeezing realize multistage dehydration, reach the purpose of the high mass dryness fraction dehydration of mud, water ratio is reduced to below 60.0%.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of spiral concentrates belt osmosis vibration squeezing integration apparatus, be made up of feeding system, medicine system, Preblend system PBS, delivery system, spiral thickening system, belt press dewatering system, osmosis press dewatering system, vibration press dewatering system, delivery system is made of strainer, strainer automatic cleaning system, filter belt automatic deviation rectifying system, strainer auto-tensioning system.
Described spiral thickening system sends into a diameter in the screw conveying structure that increases gradually with the material of flocculation, screw rod is the jogging speed rotation in the screen cloth of a round tube type, and material is extruded dehydration and is transported forward simultaneously in the spiral that pressure increases gradually.Material stands the pressure dehydration of long period in the screw extrusion filter.At the material that screw shaft one end enters, press to along with screw shaft that water ratio descends gradually in the process of the other end.Described belt press dewatering system be the material of spiral thickening system output behind double-deck strainer parcel through vertical layout, the squeeze roll of descending arrangement, material are subjected to the effect of squeeze roll shearing force, water ratio further reduces, and forms filter cake shape.
Described osmosis press dewatering system be material under the effect of DC electric field, water is released in the born of the same parents, the water ratio of filter cake shape material further reduces under the squeezing action of squeeze roll.
Described vibration press dewatering system is made of squeeze roll, vibrations post, belt, excentric shaft.The excentric shaft high frequency rotates and to cause that belt is lax and tensioning state, drives the extruding of vibrations post and away from filter cloth.Under the effect of high-frequency vibration and squeeze force, the water ratio of filter cake shape material further reduces.
Advantage and the positively effect that the utlity model has are: (1) greatly reduces water ratio.This equipment directly is reduced to 99.2%～95.0% high water content sludge below 60.0%, has reduced the volume of mud greatly, for the ultimate disposal of mud is laid a good foundation.(2) save floor space.This equipment adopts vertical layout, compact construction, and floor space is little, the upgrading of the sewage work that is particularly useful for having built up.(3) improve the employee work environment, avoid environmental pollution.This equipment can be processed into hermetic type, and the hermetic type integration apparatus has not only guaranteed health of operators, and has avoided the pollution of foul gas to environment.(4) production and unattended operation continuously.This equipment is realized continuity production and the automated operation of the high mass dryness fraction dehydration of high water content sludge.(5) energy consumption is low, the dewatering efficiency height.This equipment integration technology such as belt press dewatering, osmosis press dewatering, vibration press dewatering, reduce the dehydration energy consumption, improve dewatering efficiency.
