Description

A kind of super-pressure sludge high-drying degree dehydration device

Technical field

Sewage Sludge Treatment Techniques field is the utility model is related to, specifically a kind of super-pressure sludge high-drying degree dehydration Device.

Background technology

Sludge high-moisture percentage is the bottleneck that govern specific resistance to filtration, and the high sludge of moisture content is not only bulky, and It is right and contained a large amount of organic matters, heavy metal and harmful microorganism is also easily degenerated or be discharged into environment, causes secondary pollution All adversely affected in the follow-up landfill of sludge, burning, recycling etc..Therefore, deeply dehydrating sludge minimizing is Treatment of Sludge primary and foremost purpose, minimizing are to realize the basis of sludge other " three change ", and sludge is more dry, and subsequent treatment disposal more has Profit.

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 dehydrated sludge moisture content typically in 75%-80%, these sludge because moisture content is too high, cause transport inconvenience and cost compared with Height, and in landfill yard Direct Disposal drying time can not be caused to grow, the large amount of organic and abundant nitrogen phosphorus contained in sludge The nutrients such as potassium, perishable generation stench cause environmental pollution.

It is in the prior art diaphragm plate frame filter press with more deep dehydration device for sludge, squeeze pressure is only 1.6MPa, less efficient, moisture percentage in sewage sludge is higher.As shown in Figure 1-2, when Fig. 1 is barrier film non-bulging, barrier film is close to filter plate On, now dehydration is dehydrated by the feed pressure of mud, pressure typically in 0.8-1.0MPa, Fig. 2 be high-pressure hydraulic pump inject water into every Diaphragm plate inframe portion, bulging barrier film reduce filter chamber area, now diaphragm deflection, but as seen from the figure, diaphragm edge is fixed, deformation Measure very little, and centre position deformation is then very big, the structure inevitably results in sludge and differed by barrier film bulging degree, edge sludge by Bulging degree is small, and middle big by bulging degree, sludge compression degree can be brought different, moisture content is also different, diaphragm plate frame pressure Than small, chamber variable amplitude is small for contracting.In addition, on the market on common elasticity squeezing sheet frame its structure construction, filter is all one Individual overall injection module, filter easily be damaged deformation, and damage after filter need integral replacing so that safeguard into This is higher, it is often more important that, because design feature and squeeze pressure be not high, the currently employed diaphragm plate frame filter press may be by city Political affairs sludge pressing is dehydrated to 60% or so, is 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 over dry mud amount 30% or so lime and molysite, so as to considerably increase the amount of sludge, and after the lime added and iron chloride etc. are to sludge Continuous processing disposal brings detrimental effect, runs counter to the minimizing of specific resistance to filtration and innoxious principle.

There is a kind of super-pressure diaphragm plate frame filter press in the prior art, the equipment is in original diaphragm plate frame filter press On upgrading, provide sludge nearly 10MPa pressure by the water that 10MPa is injected in barrier film, and squeezed for two level Journey, that is, feed pressure is begun through, highly pressurised liquid is then injected in barrier film, carry out bulging to barrier film is further carried out to sludge Press dewatering, municipal moisture percentage in sewage sludge can be down to 50% or so after equipment dehydration.Except prior figures 1-3 be present in the equipment The problems of it is outer, an also subject matter be barrier film under so high pressure and large deformation, the service life of barrier film Problem.

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.

The compressibility of sewage sludge is good, and compression ratio is big, wants to realize to the dehydration of sludge high-drying degree, then sludge must be carried out Depth-compression, so, the changeability of press filtration chamber size and significantly changeability are to realize the key of high mass dryness fraction dehydration.

Sludge thickness is typically in 25-35mm, from filtration theory, sludge filtration effect and mistake after current press dewatering It is directly proportional to filter power, is inversely proportional with filtration resistance, mud cake is thicker, and the resistance of moisture outflow is bigger, and filtration resistance is bigger, filtering effect Fruit is poorer, so, in order to mitigate filtration resistance, filter effect is improved, sludge should be thinner；But sludge is excessively thin, can influence to locate Efficiency is managed, now it is necessary to ensure mud handling capacity and treatment effeciency by reducing the squeezing time.

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 problems；(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, and the sludge on filter plate is close to is more solid, easily forms one The closely knit sludge blanket of layer, the sludge blanket are bonded on filter cloth, increase moisture discharge resistance, influence dehydrating effect；(4) due to sewage 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, it is difficult that high depth dehydration is carried out to sludge completely using mechanical pressure；(5) all pressure arises directly from height The pressure of compressing cylinder, not by the enlarger of any power, cause oil cylinder working-pressure and oil cylinder volume excessive, to equipment sealing and Reliability propose higher requirement；(6) sludge is blocked up, increases filtration resistance, causes costs and poor dehydration results, mud cake inner aqueous Rate is still higher, and sludge overall moisture content is difficult to drop to lower degree.
