Description

The black water down-hole treatment system
Technical field
The present invention relates to a kind of solid-liquid isolated by filtration system, particularly a kind of black water down-hole treatment system.
Background technology
Coal is as important basic energy resource and raw material, and in the draining outward simultaneously of mining, various water sources contact with coal, rock in the exploitation process, and it is the maximum waste water of discharging in the coal production process that generation one is listed as the mine water that reacts and produce.The energy-saving and environmental protection of coal mine recycling of water resource can solve the problem of colliery lack of water, are the keys that solves Sustainable Development in Mining Areas, also are must selecting then of sustainable development.
Suspended solids content is higher in the mine water; Conventional process is a dosing coagulant, and again through precipitation process, this just need add a large amount of medicaments; And disposal ability is limited, is because big material of coal water causes with each kind part, rubble etc. more than 80% in the sewage disposal system mechanical breakdown.In the mine water processing procedure, the preliminary treatment of coal water cinder is the technical barrier of whole technical process, and pretreating effect directly closes the economic benefit, social benefit and the service life of equipment to mine water treatment system.
In the prior art; The down-hole black water is handled all over the traditional coal water cinder pretreatment mode of employing, and mostly sets up on the ground, and the processing of water and reuse fed distance are long; Power-equipment and pipeline investment are big; In running, there are technology backwardness, inefficiency, operating cost is too high, floor space is big, service life of equipment is short, equipment corrosion-vulnerable, maintenance cost high and safeguards problems such as loaded down with trivial details, and all will stop production during the annual maintenance of equipment, cause waste water directly to efflux.Simultaneously, there are problems such as volume is big in conventional black water separator, and the lane space in the mine is limited, has limited the application of existing black water separator in the down-hole.
Summary of the invention
The purpose of this invention is to provide a kind of slurry circulating system practical, simple to operate, that operating cost is low, small-sized, that can be used for the down-hole.
The objective of the invention is to realize through following technical scheme:
Black water down-hole treatment system of the present invention, this system layout comprise collecting-tank, inclined-plate clarifying basin, intermediate pool, black water separator and clear water reserviors in the down-hole;
The import of said collecting-tank is provided with water inlet pipe; The outlet of said collecting-tank is connected with the import of said inclined-plate clarifying basin through elevator pump; The bottom of said collecting-tank is provided with discharge pipeline, and the outlet of said collecting-tank is connected with the import of said intermediate pool, and the outlet of said intermediate pool is connected with said black water separator through measuring pump; The outlet of said black water separator is connected with said clear water reserviors, and the outlet of said clear water reserviors is provided with supply-water pump.
Technical scheme by the invention described above provides can be found out, slurry circulating system provided by the invention is owing to be applied to the mine water pretreatment stage with the black water separator; Can be arranged in the down-hole; And in processing procedure, need not to add chemical coagulator and flocculant, solved many shortcomings that present slurry circulating system exists; Have practical, simple to operate, operating cost is low, characteristics such as efficient, safe, is particularly suitable for the down-hole treatment of black water.
