Description
Technical field
The present invention relates to sewage sludge process field, specifically a kind of high throughput sewage sludge depth minimizing side
Method.
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
Landfill, burning, the recycling of mud subsequently etc. is all adversely affected.Therefore, deeply dehydrating sludge minimizing is sludge
Primary and foremost purpose is handled, minimizing is the basis for realizing sludge other " three change ", and sludge is more dry, disposes more favourable to subsequent treatment.
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 is typically in 75%-80%, and these sludge are too high because of moisture content, and cause transport inconvenience and into
This is higher, and in landfill yard Direct Disposal drying time can not be caused long, the large amount of organic that contains in sludge and abundant
The nutrients such as N P and K, perishable generation stench causes 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 is extruded；Diaphragm plate frame compression ratio is small, long 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
Being damaged the filter after deformation, and 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,
Plate and frame filter press moisture content reduction than before is many, and 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 that greatly
The meetings such as the amount of sludge, and lime and iron chloride of the addition processing disposal follow-up to sludge is added greatly 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. constitute, 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, separation of solid and liquid is carried out by the pressure of feed pump while charging, i.e., once filters 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, passes through elasticity biography
Power apparatus (spring) compresses chamber space and squeezing progress second dehydration is carried out to material.By carrying out super-pressure squeezing to sludge,
Squeeze pressure is in 5MPa or so, and high-pressure oil pump needs to provide 25-30MPa or so 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 by setting spring to realize
Super-pressure is extruded, and because spring often completes the processes such as elongation-compression, it is necessary to bear alternate load, fatigue easily occurs for spring
Destruction, spring is that 10-20 high-strength spring is needed between a kind of consumable accessory, and every group of sheet frame, and 50-100 block sheet frames are then needed
Will nearly 1000-2000 high-strength spring, moreover, the elastic force for also needing to overcome spring initial when extruding spring is made
With squeeze pressure actual suffered by sludge is smaller than the pressure that superpressure oil pump is supplied to 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 had elastic force,
This partial pressure is the pressure of consumption, so as to cause high-pressure pump to be less than actual pressure to the pressure produced 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, provide nearly 10MPa pressure by injecting 10MPa water in barrier film to sludge, be also for two grades of 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.The equipment is in the presence of a subject matter
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 at present there is following subject matter in deep dehydration device for sludge：(1) it is common
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
And substantial amounts of squeeze pressure can be consumed；(3) pressure is bigger, more solid in the sludge being close on filter plate, easily forms one
The closely knit sludge blanket of layer, the sludge blanket is bonded on filter cloth, increase moisture discharge resistance, influences dehydrating effect；(4) due to sewage
High-compressibility, high-moisture percentage and the sewage sludge that sludge has contain capillary water, adsorb sludge dewatering caused by water and internal water
Difficult the characteristics of, 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 seal and reliability propose higher requirement.
The content of the invention
In view of this, the consumable accessory that the present invention exists for above-mentioned prior art is more, high energy consumption, oil cylinder working-pressure requirement height,
Dehydrated sludge moisture content still higher technical problem, proposes that a kind of few easy workout part, energy consumption are low, dehydrated sludge moisture content is relatively low
