Abstract
The invention discloses a circulating system for secondary utilization of slime water. The circulating system comprises the slime water, a concentration device, coal slime, a concentrated pump tank, a secondary clarification and concentration device, a clean water tank and a production system, wherein the slime water is pressed and filtered by the concentration device to form the coal slime; the concentration device is connected with the concentrated pump tank; the concentrated pump tank is connected with the secondary clarification and concentration device; the clean water tank is connected with the production system. With the adoption of the manner, produced wastewater obtained by secondary clarification treatment through the circulating system for the secondary utilization of the slime water reaches standards of clean water for production and a production water supply system is improved.
Description
Technical field
The present invention relates to coal preparation technology field, particularly relate to the recycle system that a kind of black water secondary utilizes.
Background technology
Coal separation mainly utilizes coal and spoil physical properties and chemical qualitative difference and carries out sorting, in coal separating plant, removes the impurity in raw coal with mechanical means, it is divided into the product of different mass, specification, to adapt to the requirement of different user.Coal preparation method mainly divides wet coal preparation and dry coal preparation, wet coal preparation is mainly to adopt wet concentration, due to wet coal preparation run into coal moisture when high argillization serious, and there is frozen problem at extremely frigid zones, dry coal preparation can be avoided above contradiction, as wet coal preparation being done to necessary supplementing, dry coal preparation technical matters is simple, less investment, production cost be low, take up an area less, instant effect, more has Special Significance for the coal processing of building the vast middle-size and small-size local mine of coal separating plant's insufficient funds and drought and water shortage area, extremely frigid zones.There is a large amount of dusts in coal works, needs efficient cleaning apparatus.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the recycle system that a kind of black water secondary utilizes, and through post-defecation factory effluent after treatment, has reached and has produced the standard with clear water, has improved water of productive use system.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the recycle system that provides a kind of black water secondary to utilize, comprise: black water, concentrating unit, coal slime, concentrated pump pond, post-defecation concentrating unit, clean water basin and production system, described black water forms coal slime through concentrating unit press filtration, described concentrating unit is connected with concentrated pump pond, described concentrated pump pond is connected with post-defecation concentrating unit, and described clean water basin are connected with production system.
In a preferred embodiment of the present invention, described post-defecation concentrating unit is connected with clean water basin.
In a preferred embodiment of the present invention, described production system is accompanied with product tape water.
In a preferred embodiment of the present invention, described concentrated pump pond is made up of settling tank.
The invention has the beneficial effects as follows: the recycle system that black water secondary of the present invention utilizes, through post-defecation factory effluent after treatment, reach and produced the standard with clear water, improve water of productive use system.

In accompanying drawing, the mark of each parts is as follows: 1, black water, 2, concentrating unit, 3, coal slime, 4, concentrate pump pond, 5, post-defecation concentrating unit, 6, clean water basin, 7, production system, 8, product tape water.
Embodiment
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
The recycle system that a kind of black water secondary utilizes, comprise: black water 1, concentrating unit 2, coal slime 3, concentrated pump pond 4, post-defecation concentrating unit 5, clean water basin 6 and production system 7, through concentrating unit, 2 press filtrations form coal slime 3 to described black water 1, described concentrating unit 2 is connected with concentrated pump pond 4, described concentrated pump pond 4 is connected with post-defecation concentrating unit 5, and described clean water basin 6 are connected with production system 7.
In addition, described post-defecation concentrating unit 5 is connected with clean water basin 6.
In addition, described production system 7 is accompanied with product tape water 8.
In addition, described concentrated pump pond 4 is made up of settling tank, through post-defecation, makes recirculated water reach water of productive use standard.
The beneficial effect of the recycle system of black water secondary of the present invention utilization is:
Through post-defecation factory effluent after treatment, reach and produced the standard with clear water, improve water of productive use system.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
