Summary of the invention
The purpose of this utility model is that design provides a kind of new moulded coal water Integrated Processing Unit, by each technology of comprehensive employing, thereby thoroughly solve treatment effect that prior art exists not significantly, can't accomplish the reuse of water and effectively reduce production costs and environmental issue.
The utility model adopts following technical scheme:
A kind of new moulded coal water Integrated Processing Unit, it comprises coal water equalizing tank, electrochemical flocculator, many reaction warehouses coal water treating device, strainer and coal slime dewatering device, the outlet of described coal water equalizing tank links to each other with the inlet of the electrochemical flocculator of a plurality of parallel connections, the outlet of each electrochemical flocculator feeds in described many reaction warehouses coal water treating device, the coal slime outlet of many reaction warehouses coal water treating device communicates with described coal slime dewatering device, and the water outlet of many reaction warehouses coal water treating device links to each other with described strainer.
Many reaction warehouses coal water treating device can adopt the existing various coal water treating device that a plurality of reaction warehouses are arranged, and a kind of preferred scheme adopts the many reaction warehouses coal water treating device with following structure:
Many reaction warehouses coal water treating device is made of reaction zone and settling region, it comprises water-in, water outlet and mud discharging mouth, described reaction zone adopts dividing plate to be separated into a plurality of reaction warehouses, aperture between each reaction warehouse communicates successively, two apertures in each reaction warehouse are arranged at the upper and lower part respectively, and adopt the axis to form certain included angle in design, and two apertures of the head and the tail in entire reaction district connect water-in and settling region respectively; Described settling region adopts the tube settling structure, and the inlet port position of settling region is arranged at the bottom; Described water outlet is arranged at the top of settling region; The bottom of described reaction zone and settling region all is connected with mud discharging mouth.The axis angle in two apertures in each reaction warehouse is designed to 90 degree.Because the aperture forms the diagonal angle in a pond body staggered, the jet action of consequent aperture is stronger, forms current and can produce swirling flow successively in each reaction warehouse, the suspended substance flocculation is quickened, thereby increased precipitation capacity.Described reaction zone, reaction warehouse design are rectangle.Both be easy to arrange the floor space of also saving whole device.
The coal water equalizing tank comprehensive adjustment water quality and the water yield, and reach the purpose of preliminary sedimentation.
The electrification flocculator comprises reactor, is located at the outer magnetic pole of reactor and is located at the interior magnetic fillers of reactor.Under magnetic action, electrochemical flocculator can be condensed into the subparticle in the coal water big floc sedimentation, and carries out preliminary separation.A plurality of (as more than two) electrochemical flocculator is parallel with one another can to solve the problem that electrochemical flocculator processing speed is slow, treatment capacity is little.
Described filter design adopts the quartz sand filtration device.After filtering, make suspended substance≤10mg/L in the water.
Contain that the suspended substance removal rate can be up to more than 99.9% in the coal waste water after the utility model is handled, its suspended substance mean value only is 10mg/L, and its discharge index all is lower than national specified discharge standard; A large amount of process waters has been saved in the recyclable utilization of waste water after treatment.The utility model is the waste water treatment efficiency height not only, can make waste water after treatment reach recycling: and science and engineering skill has also solved the fuel-burning power plant and has contained coal standard wastewater discharge problem herein, simultaneously after adopting present technique, can realize that also coal slime is by the direct utilization after separating, really realize the second stage employ of the energy, effectively reduced the production cost of coal-fired power plant.
