Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, be the treating apparatus of radioactive contamination waste water provided by the invention, this device comprises waste water circulation induction system and gas delivery system.
Waste water circulation induction system comprises the waste water storage groove 9, discharge pump 10, water leg 6, ebullator 7 and the high-pressure micro-mist system 5 that connect successively.Wherein, the water intake end of waste water storage groove 9 is connected with wastewater effluent pipeline.
Gas delivery system comprises aspiration leg 1 and steam heater 2, and one end of steam heater 2 is connected with aspiration leg 1, and the other end is connected with high-pressure micro-mist system 5; High-pressure micro-mist system 5 is provided with gas exhaust duct 12, and the end of gas exhaust duct 12 connects chimney 11.In order to ensure that the effect be vented reaches desirable, gas exhaust duct 12 is provided with exhaust blower 4.
Wherein, the bottom of high-pressure micro-mist system 5 is provided with Drainage pipe 13, and Drainage pipe 13 is connected with water leg 6.Thus not by the pollutant effluents that hot-air absorbs in high-pressure micro-mist system 5, collect in water leg 6 through Drainage pipe 13, and then enter pressure atomization system for high 5 through ebullator 7 and carry out spray absorber.
Connecting tube between steam heater 2 and high-pressure micro-mist system 5 is provided with air intake filtrator 3, in order to be filtered by the air through heating.
Connecting tube between ebullator 7 and high-pressure micro-mist system 5 is provided with effluent filter 8, in order to the bulky grain thing in filtered wastewater.
Two ebullators 7 and two discharge pumps, 10, two ebullators 7 and two discharge pumps 10 can be set up in parallel in waste water induction system can be used alone, also can use simultaneously.
Multiple waste water storage groove 9 is set in waste water induction system, ensures the output of pollutant effluents.
Outdoor air of the present invention is after aspiration leg 1 inertial dust collection removing bulky grain, heat through steam heater 2, granule is removed again through air intake filtrator 3, fully contact with the radioactive contamination waste water after atomization after entering high-pressure micro-mist system 5, pollutant effluents is vaporized, air moisture content increases, and the air-flow after humidification finally by chimney high altitude discharge, thus reaches the object of pollutant effluents to air venting.
The treating apparatus that the invention provides pollutant effluents overcomes the drawback adding hot-air dossal air carrier band scheme.By chimney high altitude discharge, make pollutant effluents enter the so infinitely-great acceptor of air, pollutant effluents is not accumulated, avoid polluting surrounding soil and water body, meet environmental protection requirement, guarantee the continuous trouble-free operation of factory and safety of surrounding environment.This device be easy to control, simultaneously investment and operating cost relatively low.
For condensation does not appear in the air-flow of using chimney, the temperature that should control out chimney draft is lower than environment temperature 1 DEG C, relative humidity about 70%.
It should be noted that, the pollutant effluents of process of the present invention is radioactive waste water or inactive waste water.
The treating apparatus of pollutant effluents of the present invention is not limited to above-mentioned embodiment, and those skilled in the art's technical scheme according to the present invention draws and other embodiment belongs to technological innovation scope of the present invention equally.
