Description
Technical field
The present invention relates to a kind of tertiary industry product liquid-solid fluid bed separation coarse slime system and its techniques, are particularly suitable for coal point
Select the difficult desulfurization and deashing for selecting coarse slime in technique.
Background technique
China is one using coal as the country of main energy sources, and it is most effective that the sorting of coal is that Coal Clean efficiently utilizes
Measure, coal preparation technique and method gradually mature and perfect, form " major diameter heavy medium cyclone sorting+separation of coarse slime+floating
The three-stage prevailing technology of choosing ".And limit for height (being greater than 1mm) under the sorting granularity of major diameter heavy medium cyclone, flotation is suitable
For upper size boundary in 0.25mm or so, this makes the sorting of coarse slime with regard to necessary.In separation of coarse slime equipment, with two products
Using relatively broad, material size bound fineness ratio controls within 4 times liquid-solid fluid bed separation machine, and the difficult choosing of its sorting
When coal, the efficiency of separation is often low, causes to carry the higher middle coal of ash content in cleaned coal secretly, and is mingled with coal in a large amount of in spoil, most
Showing as cleans ash and ash content in refuse eventually can not guarantee simultaneously.Therefore providing a kind of sorting hardly possible selects the technique of coarse slime just to have very much
It is necessary.
Summary of the invention
Technical problem: the purpose of the present invention is to solve current coarse slime material size narrow ranges, sort difficulty and select rough coal
When mud, cleans ash and the problem that ash content in refuse can not guarantee simultaneously and the efficiency of separation is low provide three product liquid of one kind and flow admittedly
Change bed fine coal system and technique, which can relax material size range in fine coal, particularly suitable
The sorting of coarse slime is selected in hardly possible, can guarantee cleans ash and ash content in refuse simultaneously, and have the relatively high rate of recovery.
Technical solution: tertiary industry product liquid-solid fluid bed separation coarse slime system of the invention, including desliming screen, dense media eddy flow
Device, cleaned coal magnetic separator, closes Jie's bucket, classifying cyclone, the product liquid-solid fluid bed separation of coarse slime machine of tertiary industry and rough coal at middle coal magnetic separator
Coal sieve bend in mud, the heavy medium cyclone are connected with the oversize of desliming screen, and stream device and desliming screen are applied in the classification
Screenings is connected, and the product liquid-solid fluid bed separation of coarse slime machine of tertiary industry is connected with classifying cyclone underflow, the rough coal
Coal sieve bend is connected with the outlet of the middle coal slime of the product liquid-solid fluid bed separation of coarse slime machine of tertiary industry in mud, coal sieve bend in coarse slime
On-the-sieve material outlet with conjunction Jie's bucket be connected, conjunction Jie's bucket is connected with heavy medium cyclone by the road.
Using the tertiary industry product liquid-solid fluid bed separation coarse slime technique of above system, the underflow including classifying cyclone enters
The product liquid-solid fluid bed separation of coarse slime machine of tertiary industry, through the product liquid-solid fluid bed separation of coarse slime machine of tertiary industry generate cleaned coal mud, middle coal slime,
Three kinds of products of tail coal mud, further includes:
The middle coal slime is sent into coal sieve bend in coarse slime to be dehydrated, allows the oversize of coal sieve bend in coarse slime
Into Jie's bucket is closed, Jie's ladle mixing material will be closed and be sent into heavy medium cyclone, mixed with the oversize of desliming screen, through dense media
After cyclone sorting, underflow and overflow respectively enter the link that middle coal de-mediated dehydration and cleaned coal de-mediated are dehydrated.
The slot size of the desliming screen and the revolving speed of heavy medium cyclone can be adjusted as needed, and can be used for 3
~0.25mm separation of coarse slime, can be used for the sorting of -0.5mm coal slime.
The sorting that the mixed material closed in Jie's bucket enters dense medium cyclone is pressurized feeding, and coarse granule on desliming screen
It is unpressurized feeding into dense medium cyclone, realizes the combination of a cyclone coarse grain unpressurized feeding and coarse slime pressurized feeding.
The utility model has the advantages that stating technical solution due to having used upper, the present invention can relax material size model in fine coal
It encloses, is applicable not only to two product dense medium cyclones, is also applied for three-product HM cyclone, select coarse slime especially suitable for hardly possible
Sorting, and can guarantee cleans ash and ash content in refuse simultaneously, and have the relatively high rate of recovery.By column diameter expansion or multistage string
Connection is formed by multi-product liquid-solid fluid bed separation of coarse slime, solves current coarse slime material size narrow range, sorts difficult choosing
When coarse slime, cleans ash and the problem that ash content in refuse can not guarantee simultaneously and the efficiency of separation is low, compared with the prior art, energy
By adjusting the screen slot size of desliming screen, to the adaptable of raw coal coal slurry content variation, due to being three products, middle coal slime according to
Concrete condition can mix tail coal mud either cleaned coal mud, the strong flexibility of technique, middle coal slime and enter in heavy medium cyclone again
Sorting, the clean coal recovery made improve.
