Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1, a kind of Extraction of rare eart wastewater treatment equipment, including evaporator 1, flash column 2, jet pump 3, cooling
Crystallizer 4, centrifuge 5, feeding pipe 6, slurry delivery tube 7;
The evaporator 1, the flash column 2, the cooler crystallizer 4, the centrifuge 5 pass sequentially through pipe from left to right
Road connects;The evaporator 1 is open-top receptacle, and 1 right side of the evaporator is provided with feeding mouth 11, and the feeding pipe 6 is set vertically
It sets between the flash column 2 and the cooler crystallizer 4, the feeding pipe 6 bends in 90 ° in bottom end and crosses over the flash distillation
Tower 2 is then connected to the feeding mouth 11;Connect by the slurry delivery tube 7 between the flash column 2 and the cooler crystallizer 4
It connects, it is in the horizontally disposed feeding pipe 6 that 7 front half section spiral windings of the slurry delivery tube, which are lived after bending,;
The jet pump 3 is arranged in the open top of the evaporator 1, the air entry of the jet pump 3 and the sudden strain of a muscle

31 are also equipped with spray equipment;The spray equipment includes spray head 33 and the connection spray head 33 and the jet exit
31 adapter 32;
The flash column is internally provided with temperature control equipment 21.
When work, after evaporator 1 evaporates waste water, flash column 2 is vacuumized by jet pump 3, useless to what is tentatively evaporated
The flash distillation process that water is depressured, and the temperature control equipment 21 being arranged in flash column 2 can pass through the sensor sense of itself
It by the temperature in tower, and is realized according to the heating device of the variation adjustment flash column 2 of temperature and adjusts temperature so that in waste water
NH4Faster, energy consumption is lower for the crystallization of Cl, while a large amount of waste-heat evaporators 1 that while being run using flash column 2 is generated, including
The upper surface of liquid in the evaporator 1 is ejected by jet pump 3 from the steam above flash column 2, and under flash column 2
7 spiral winding of slurry delivery tube of Fang Liuxiang cooler crystallizers 4 heats the waste liquid of pan feeding to feeding pipe 6, so that evaporator 1 is reduced and adds
Energy consumption needed for heated effluent, and the temperature of slurry in slurry delivery tube 7 is reduced simultaneously, make its more rapid cooling in cooler crystallizer 4
But.
Further, the jet pump 3 is steam ejector pump.
Jet pump 3 sprays into sucking gas by the high speed of medium and is vacuumized, then medium together with the gas of sucking
Eject the external world, one of this embodiment preferably in, using steam ejector pump, using vapor as medium sucking from sudden strain of a muscle
The steam that tower 2 transmits is steamed to spray together to the liquid level of evaporator 1.Heating effect can be enabled more preferable, do not introduce other impurities.
