Description
Technical field
The present invention relates to sewage sludge process field, specifically a kind of multi-chamber sludge high-drying degree dehydration device.
Background technology
Sludge high-moisture percentage is the bottleneck for restricting specific resistance to filtration, and the high sludge of moisture content is not only bulky, and
Contained a large amount of organic matters, heavy metal and harmful microorganism is also easily degenerated or is discharged into environment, causes secondary pollution, to dirt
The follow-up landfill of mud, burning, recycling etc. all adversely affect.Therefore, deeply dehydrating sludge minimizing is sludge
Primary and foremost purpose is handled, minimizing is to realize the basis of sludge other " three change ", and sludge is more dry, subsequent treatment is disposed more favourable.
The conventional dehydration equipment of early stage sludge has plate and frame filter press, drum centrifuge and belt type filter filter press, through these
Equipment dehydration after, moisture percentage in sewage sludge typically in 75%-80%, these sludge because moisture content is too high, and cause transport inconvenience and into
This is higher, and in landfill yard Direct Disposal drying time can not be caused to grow, the large amount of organic that contains in sludge and abundant
The nutrients such as N P and K, perishable generation stench cause environmental pollution.
It is in the market diaphragm plate frame filter press with more deep dehydration device for sludge, but in dehydration, efficiency
Relatively low, squeeze pressure is only 1.6MPa, and it, which is squeezed, is injected sewage inside diaphragm plate frame by high-pressure hydraulic pump, and bulging barrier film reduces
Filter chamber area, the plastic deformation of diaphragm plate frame backup plate frame extrude；Diaphragm plate frame compression ratio is small, is grown with respect to the work period.In addition,
Common elasticity squeezing sheet frame is on structure construction on the market, and filter is all the injection module of an entirety, and filter is easy
Impaired deformation, and the filter after damage needs integral replacing so that maintenance cost is higher, it is often more important that, due to structure
Feature and squeeze pressure be not high, the currently employed diaphragm plate frame filter press may by municipal sludge press dewatering to 60% or so,
Reduced much than plate and frame filter press moisture content before, main cause is because barrier film bulging produces twice pressing to sludge, i.e.,
Sludge press filtration chamber is variable chamber, but the equipment needs to add the lime and molysite of over dry mud amount 30% or so, so as to big
The big amount for adding sludge, and the processing disposal that the lime added and iron chloride etc. can be follow-up to sludge brings unfavorable shadow
Ring, run counter to the minimizing of specific resistance to filtration and innoxious principle.
Currently there is a kind of superelevation compression elasticity squeezing sludge dewatering equipment, the equipment mainly includes high-voltage oil cylinder, superelevation press filtration
Plate, matching board, spring medium, filter cloth specialized, tailgate, push pedal, girder etc. form, the super-pressure squeezing sheet frame include filter frame, filter plate,
Filter cloth, operating room, spring and piston plate, spring are arranged between filter frame and filter plate, piston plate be arranged on operating room and filter plate it
Between so that filter plate produces compression by piston plate to operating room.Rammer board dehydration is broadly divided into two-stage, and the first order is
Filter chamber is transported material to by feed pump, carries out separation of solid and liquid by the pressure of feed pump while charging, i.e., once filtering is de-
Water；The second level is elastic squeezing, and one end of equipment is fixed, and the other end applies ambient pressure by hydraulic jack, is passed by elasticity
Power apparatus (spring) compresses chamber space and squeezing progress second dehydration is carried out to material.By carrying out super-pressure squeezing to sludge,
In 5MPa or so, high-pressure oil pump needs to provide 25-30MPa or so pressure squeeze pressure, moisture percentage in sewage sludge can be down into 50%
Left and right.Equally, the superelevation compression elasticity squeezer realizes the change to sludge pressing chamber volume to realize by setting spring
Super-pressure extrudes, and because spring often completes the processes such as elongation-compression, it is necessary to bear alternate load, fatigue easily occurs for spring
Destroy, spring is a kind of consumable accessory, and 10-20 high-strength spring is needed between every group of sheet frame, and 50-100 block sheet frames then need
Will nearly 1000-2000 high-strength spring, moreover, the elastic force for also needing to overcome spring initial when extruding spring is made
Actual squeeze pressure is smaller than the pressure that superpressure oil pump is supplied to suffered by sludge during, twice pressing.For example, charging pressure
When power is 1MPa, spring must be provided more than 1MPa elastic force so that the maximization of chamber can be kept between filter plate and filter frame, when entering
At the end of material squeezing, when high-pressure pump carries out second of high-pressure compressing to sludge, it is necessary to overcome spring to start possessed elastic force,
This partial pressure is the pressure of consumption, so as to cause high-pressure pump to be less than actual pressure to pressure caused by sludge.
Existing market also has a kind of super-pressure diaphragm plate frame filter press, and the equipment is on original diaphragm plate frame filter press
Upgrading, by barrier film inject 10MPa water to sludge provide nearly 10MPa pressure, and be two level expressing process,
Feed pressure is begun through, highly pressurised liquid is then injected in barrier film, carrying out bulging to barrier film further presses sludge
Dehydration is squeezed, municipal moisture percentage in sewage sludge can be down to 50% or so after equipment dehydration.A subject matter be present in the equipment
Barrier film influences the problem of the service life of barrier film under so high pressure and large deformation.
Analyzed more than, it can be seen that to realize that the deep dehydration of sludge has to realize sludge pressing chamber volume
Changeability, while to sludge carry out high-pressure compressing.Either diaphragm plate frame filter press or superelevation compression elasticity squeezer all has
There is the changeability of sludge pressing chamber, but deep dehydration device for sludge has following subject matter at present：(1) commonly
The sludge pressing pressure of diaphragm plate frame filter press is smaller, and super-pressure diaphragm plate frame filter press squeeze pressure is enough, but barrier film
Life-span is not high；(2) superelevation compression elasticity squeezer is the change for realizing sludge pressing chamber volume by spring, and spring is fragile

High-compressibility, high-moisture percentage and the sewage sludge that sludge has contain capillary water, absorption water and sludge dewatering caused by internal water
The characteristics of difficult, completely using mechanical pressure be difficult to sludge carry out high depth dehydration so that moisture percentage in sewage sludge reach one compared with
Low level；(5) all pressure arises directly from the pressure of high-voltage oil cylinder, not by the enlarger of any power, causes
Oil cylinder working-pressure and oil cylinder volume are excessive, to equipment sealing and reliability propose higher requirement.
