Embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is described in further detail.
As shown in figure 1, it is the processing unit of radioactive pollution waste water provided by the invention, it is defeated that the device includes waste water circulation
Send system and gas delivery system.
Waste water circulation induction system include be sequentially connected waste water storage groove 9, delivery pump 10, water leg 6, circulating pump 7 with
And high-pressure micro-mist system 5.Wherein, the water intake end of waste water storage groove 9 is connected with wastewater effluent pipeline.
Gas delivery system includes induced draught tower 1 and steam heater 2, and one end of steam heater 2 is connected with induced draught tower 1
Connect, the other end is connected with high-pressure micro-mist system 5；High-pressure micro-mist system 5 is provided with discharge duct 12, the end of discharge duct 12
Connect chimney 11.In order to ensure that the effect of exhaust reaches preferable, discharge 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.So as to
The pollutant effluents not absorbed in high-pressure micro-mist system 5 by hot-air, is collected into water leg 6, Ran Houzai through Drainage pipe 13
It is secondary to enter the progress spray absorber of pressure atomization system for high 5 through circulating pump 7.
Connecting pipe between steam heater 2 and high-pressure micro-mist system 5 is provided with air intake filter 3, in order to pass through
The air of heating is filtered.
Connecting pipe between circulating pump 7 and high-pressure micro-mist system 5 is provided with effluent filter 8, in order in filtered wastewater
Bulky grain thing.
Can be set up in parallel two circulating pumps 7 and two delivery pumps 10 in waste water induction system, two circulating pumps 7 and two it is defeated
Send pump 10 can be used alone, can also use simultaneously.
Multiple waste water storage grooves 9 are set in waste water induction system, ensure the output of pollutant effluents.
Outdoor air of the present invention heats after the inertial dust collection of induced draught tower 1 removes bulky grain through steam heater 2, then through entering
Wind filter 3 remove little particle, into high-pressure micro-mist system 5 after fully contacted with the radioactive pollution waste water after atomization, make dirt
Waste water vaporization is contaminated, air moisture content increases, and the air-flow after humidification is most afterwards through chimney high altitude discharge, so as to reach pollutant effluents to sky
The purpose of gas discharge.
The drawbacks of processing unit that the present invention provides pollutant effluents overcomes heating air dossal air carrier band scheme.Pass through
Chimney high altitude discharge, pollutant effluents is entered such a infinitely great acceptor of air, pollutant effluents is not accumulated, avoid polluting
Surrounding soil and water body, meet environmental protection requirement, it is ensured that the continuous trouble-free operation of factory and safety of surrounding environment.The device is easy to
Control, while invest relatively low with operating cost.
Condensation is occurred without to use the air-flow of chimney, the temperature of chimney draft should be controlled out lower than environment temperature 1 DEG C, phase
To humidity about 70%.
