Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing, in which:
Fig. 1 is the structural schematic diagram of one preferred embodiment of abrasive material waste residue water circulation separation system of the present invention.
Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of abrasive material waste residue water circulation separation system, including cesspool 1, clear water reserviors 2, mixing pit 3, dissolving 4 and flotation tank
5。
Cesspool 1 is connected to clear water reserviors 2, and in common output to mixing pit 3, mixing pit outlet is connect with dissolving 4.
When handling the more sewage of abrasive material waste residue, the abrasive material waste residue content by dilution of sewage, in mixing pit 3 is needed with clear water
After reduction, in output to dissolving 4.
The outlet of dissolving 4 is connected with dissolved air water release 6, and the release 6 is set in flotation tank 5, and flotation tank 5 is equipped with
Waste residue outlet and clear water output, bottom of pond portion are equipped with gathering ground 7, and clear water circulating reflux is formed between the clear water output and clear water reserviors
System 8.
Waste residue outlet can be connected to sludge sump or sludge treatment device, and clear water output a part flow to clear water canal through overflow weir
Afterwards, along discharge of pipes or into next processing unit, separately some is returned in clear water reserviors by clear water circulating reflux system 8.
Gathering ground 7 is set to below clear water output, and there are part water in flotation tank always for gathering ground 7, is equipped in gathering ground 7
Dosing mouth 9, coagulant and flocculant are out of dosing mouth investment flotation tank 5, with remaining clear water fusion reaction.
Coagulant preferred polymeric aluminium chloride；The preferred polyacrylamide of flocculant.
Wherein, heating device is equipped in gathering ground 7, to accelerate merging for coagulant and flocculant and sewage.
Cesspool 1 leads directly to connection with dissolving 4, when abrasive material waste residue content is lower in cesspool 1, can be sent directly into molten
In gas tank 4, export after forming dissolved air water to flotation tank 5.
Scraping machine 10 is equipped with above flotation tank 5.After dross accumulates to certain thickness, start scraping machine 10, by scraping machine 10
Row is subsequently discharged to sludge-tank to dross canal after scraping air floatation machine sludge-tank.
Gas is provided by pneumatics device 12 in dissolving 4, ground floating ball lever meter control pneumatics device opening and closing in dissolving 4.Due to
Dissolved air water constantly takes away air in tank, and air gradually decreases in tank, and water level rises.When the water level rises to a certain position, it floats
Ball liquidometer works air compressor machine 12 is controlled, and makes have enough air capacities in tank.
Release 6 is the key device of this system, it to the size of bubble formation, distribution and to flotation waste water treatment effect and
Operating cost has a significant effect.The outgassing efficiency of current adopted release is up to 99.2%.Dissolved air water is when depressurizing energy dissipating
The release rule of bubble is different from situation of the bubble in hydrostatic；The appearance of air pocket is attributed to the bad institute of release when low pressure
It causes.In addition to release largely stable micro-bubble, it is important to how to prevent from blocking.The selection of dissolved air release should basis
Oily wastewater water quality, process flow and release performance determine.
Therefore, the present invention devises Self-cleaning system on release 6, and Self-cleaning system includes pumped vacuum systems and clear water
Cleaning system opens the tongue piece of release when cleaning, opens pumped vacuum systems and clear water cleaning system is rinsed.
When release 6 blocks, openable vacuum pumping valve opens release tongue piece, makes its self-cleaning with clear water,
Tamper is rinsed, this valve is then shut off, which generally need to only open 10-20 seconds.
Dissolving 4 is equipped with pressure gauge 11, and when circulation separation system is run, the reading of pressure gauge 11 must not exceed 0.6MPa.
Working principle is: opening the outlet valve in the pond of clear water, sewage, after mixing in mixing pit, opens dissolving water inlet
The gage pressure of control valve, dissolving is gradually increasing, and should generally reach 0.4-0.5MPa.Dissolving outlet water control valve door, makes
Dissolved air water is discharged by release to flotation tank；At this point, the dosing of the gathering ground of air bearing bottom of pond portion is completed, dissolved air water and medicine
Object is mixed, and is adhered to floccule body on fine gas bubbles, subsequently into air flotation zone.Floccule body floated under the action of lift of gas to
The water surface forms dross, the clear water of lower layer or is back to clear water reserviors, or after overflow weir flow to clear water canal, along discharge of pipes or entrance
Next processing unit.Dross on the flotation tank water surface accumulates to after certain thickness, after scraping air floatation machine sludge-tank by scraping machine
It is discharged to dross canal, is subsequently discharged to sludge-tank.
Processing capacity of the present invention is big, high-efficient, land occupation is few；Technical process and simple in equipment are easy to use, maintenance；
To going the abrasive material waste residue in water removal to have obvious effects on, simultaneously because aeration increases the dissolved oxygen in water, mentioned for subsequent processing
Advantage is supplied；With water circulation system, while good pulp water separating effect can be reached, the energy has been saved, has been reduced
Cost.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
