Description
Technical field
The present invention relates to the black water treatment unit, be specifically related to the defeated coal terminal black water treatment unit of a kind of long-distance pipe and method.
Background technology
Along with improving constantly of mining mechanization degree, in China coal separating plant feed coal＜also increasing year by year of the fine grain content of 0.5mm level, process and coal slime dewatering reclaims and increased difficulty to black water.Present black water dewatering process both domestic and external can better reclaim large coal particles, but relatively poor to the organic efficiency of fine particulate coal, causes the loss of a large amount of fine particulate coal, causes coal recovery rate to reduce the wasting of resources.
Summary of the invention
The objective of the invention is to improve to a great extent the rate of recovery of coal for pipe water delivery coal slurry terminal provides a kind of high-level efficiency, high-quality black water treatment process, increase the defeated coal terminal black water treatment unit of long-distance pipe of coal production.
Another object of the present invention is treatment process.
In order to overcome the deficiencies in the prior art, technical scheme of the present invention is to solve like this: a kind of long-distance pipe is failed coal terminal black water treatment unit, this terminal black water treatment unit comprises medicament adding device, one thickner, another thickner, the accident thickner, circulating water pool, sewage works, the power house pressure filter, special character of the present invention is that two sections of design employings are concentrated, described medicament addition device is to add flocculation agent and coagulant aids in black water, the centrifugate of described power house Sedimentation centrifugel, the sewage works underflow advances a thickner through pipeline, described power house pressure filter filtrate and a thickner overflow water advance another thickner through pipeline, and described another thickner overflow water flows into circulating water pool and is delivered to the described thickner of sewage works by water circulating pump through pipeline through pipeline, another thickner and accident thickener underflow carry out processed through pipeline entrance pressure filter.
Described medicament adding device is quadruplet, and dual-purpose two is standby.
Add medicament and comprise flocculation agent: polyacrylamide (PAM), coagulant aids: polymerize aluminum chloride (PAC); The flocculation agent consumption is 2g/m
3Black water, coagulant aids consumption are 50g/m
3Black water; Flocculation agent is added on the pressure filter filtrate pipe and the Sedimentation centrifugel filtrate pipe is said the power house place, and flocculation agent is added on thickner pan feeding buffer barrel place.It is in good time in the variation that comes coal character that dosing is wanted, and adds test according to the black water medicament, finely tunes on above-mentioned dosing basis.
A kind of long-distance pipe of described device is failed coal terminal black water treatment process, carries out in the steps below successively:
1), centrifugate and pressure filter filtrate, the drainage of sewage works underflow with the power house Sedimentation centrifugel enters a thickner;
2), power house pressure filter filtrate and a thickner overflow water drainage are entered another thickner;
3), another thickner overflow water is delivered to circulating water pool, be delivered to sewage works by water circulating pump;
4), a thickner, another thickner and accident thickener underflow are sent into pressure filter and carry out processed.
Long-distance pipe is failed coal uninterrupted duty in 24 hours, requires the non-stop run of black water treatment unit energy, and the accident thickner of setting can fully guarantee the uninterrupted processing of black water.The thickner accident is divided into simultaneously three kinds of situations of accident of a thickner accident, another thickner accident and another thickner.
1., a thickner accident: when a thickner broke down, the black water that enters a thickner transfers to the accident thickner to be processed, and several times the black water in the thickner is delivered to the accident thickner with underflow pump simultaneously, emptying rear maintenance.
2., another thickner accident: when another thickner has an accident, the coal slime that enters another thickner is transferred to the accident thickner and is processed, utilize simultaneously closed tube and underflow pump between the thickner several times the black water in another thickner to be delivered to the accident thickner, emptying rear maintenance.
3., another thickner while accident: when another thickner has an accident simultaneously, the moisture of coal fines that enters another thickner repeatedly all transfers to the accident thickner and processes, utilize underflow pump that the moisture of coal fines in another thickner repeatedly is delivered to the accident thickner, emptying rear maintenance.
The work of recovery thickner after above-mentioned break down maintenance is finished is delivered to a thickner with the whole moisture of coal fines Multiple through then out underflow pumps in the accident thickner and processes, and it is for subsequent use simultaneously the accident thickner to be overhauled, maintain rear continuation.
Pressure filter pan feeding concentration is 350～500g/L, and the moisture of product is 20%～24% after processing, and dehydration rate reaches 58%～71%.
In the ore pulp of 4,500,000 tons of coals was processed, by 1,170,000 tons of 1 year recyclable delivering dry coal slurries of this kind technique, consequent direct economic benefit was at least more than hundred million yuan; Reduced in addition the overflow water concentration after processing, reduced follow-up cost of sewage disposal, consequent indirect economic effect is also very considerable.
The present invention compared with prior art provides a kind of high-level efficiency, high-quality black water treatment process for managing defeated coal slurry terminal.The defeated coal slurry terminal black water treatment process of this pipe can be widely used in the further processing of instructing slurries in the paste materials filtered liquid.Adopt this method can improve to a great extent the rate of recovery of coal, increase coal production.
