Description
Technical field
The utility model relates to a kind of waste water recycle device, especially rare earth waste gas spray waste water recycle device.
Background technology
Rare Earth Production is smelted and separation and Extraction process has produced large quantity of exhaust gas, and traditional emission-control equipment is that tail gas is processed through spray, and spray waste water after treatment passes through water treatment again.The general technique that adopts three grades of alkali lye sprays of spray waste water, it is acid that the waste water producing is, and contains a large amount of fluorides, COD and SO42-and total salt amount.The advantage of this technique is that scale of investment is little, easy to operate, and shortcoming is that the waste water treatment expense producing is higher, and water resources consumption is larger.
Utility model content
For above-mentioned technical problem, the utility model provides the concrete technical scheme of a kind of rare earth waste gas spray waste water recycle device to be:
Rare earth waste gas spray waste water recycle device, comprise waste gas collection device, waste gas collection device is connected with spray equipment gas access, and the gas vent of spray equipment is connected with cyclone separator air inlet, the air outlet of cyclone separator is connected with blower fan, and the air outlet of blower fan is connected with filter; Waste gas is after spray equipment spray is processed, and by cyclone separator, by gas-liquid separation, the waste gas of separating is discharge after filter filters;
The liquid outlet of spray equipment is connected with settling vessel, and the supernatant outlet of settling vessel is connected with treatment pond entrance, and the outlet for the treatment of pond is connected with postprecipitation device, and the supernatant outlet of final settling tanks is connected with the shower water entrance of spray equipment; Spray after waste water produces in spray equipment, flow in settling vessel precipitation of solid material is separated, and supernatant, after treatment pond carries out chemicals treatment, then is isolated the solid of chemicals treatment generation in final settling tanks, and supernatant is got back to spray equipment and carried out reuse;
The liquid outlet of described cyclone separator is connected with settling vessel.
Between described waste gas collection device and spray equipment, also comprise a condenser, condenser is to the waste gas processing of lowering the temperature, by heat recovery and utilization.
The liquid outlet of described spray equipment, the liquid outlet of cyclone separator are connected by triple valve with settling vessel entrance.
Described treatment pond has adding medicine mouth and agitator.
The rare earth waste gas spray waste water recycle device that the utility model provides, will reuse after spray wastewater treatment again, can reduce water resources consumption.
