Embodiment
The embodiment of the present invention is further illustrated below in conjunction with accompanying drawing.
Exemplary air cleaning unit of the invention as Figure 1-3, including casing 1 and circulating sprayer 7.
The air outlet 9 of air after the front and back end of casing 1 is respectively equipped with the air inlet 2 of air to be clean and purified；Casing 1 exists
Demister 10 is provided with before air outlet 9, and air sampling mouth 17 is provided between air outlet 9 and demister 10；Inside casing 1
Bottom be provided with and be used to accommodate the cistern 16 of absorbent solution；It is molten with absorbing into pipeline 3 that the side of casing 1 is provided with absorbent solution
Liquid floss hole 8.Circulating sprayer 7 includes circulating pump 13, circulation pump frame 14, spray branch pipe 11, sprays and is set on branch pipe 11
There is nozzle 12.Spray branch pipe 11 divides three groups to be arranged on the vertical plane of air-flow direction, and every group has five rows to spray branch pipe 11, often
There are 16 nozzles 12 on row's spray branch pipe 11, these nozzles 12 send absorbent solution forth the covering whole inside gas of casing 1 in vaporific
Body space.Absorbent solution in cistern 16 is squeezed into by the spray being arranged in casing 1 by the circulating pump 13 being arranged on outside casing 1
Drench branch pipe 11.Be provided with casing 1 for detect the liquid level in casing 1 liquid level emasuring device 6, for discharging unnecessary suction
Receive the overfall 4 of solution and the inspection manhole 5 for maintenance.Circulating pump 13 is fixed on circulation pump frame 14.Whole device is led to
Anchor bolt 15 is crossed to be fixed on equipment base.
The operation principle of the present apparatus is as shown in figure 4, specific explanations are as follows：
Before ventilating system puts into operation, by absorbent solution enter pipeline 3 first the cistern 16 in casing 1 absorb it is molten
Liquid (for desalination pure water) is filled, and reaches high level alarm when liquid level emasuring device 6 measures liquid level, now cistern 16 is full of suction
Receive solution (about 5m3Capacity), unnecessary absorbent solution is overflowed by overfall 4.Stop adding absorbent solution, now ON cycle
All valves of circulation loop on spray equipment 7, close all valves and absorbent solution discharge that absorbent solution enters pipeline 3
The valve of mouth 8.Start circulating pump 13, circulating sprayer 7 is started working, and covering housing interior volume is ejected by nozzle 12
Fog-like liquid.Starting ventilating system, air to be clean is flowed into through air inlet 2, and adverse current (should be cross-flow) is formed with spray water mist,
The aerosol and chemical drop being mingled with air to be clean are trapped and be detained, it is sunk to the water storage of the bottom of casing 1
In pond 16.Air after purification contains large quantity of moisture, it is necessary to retain steam by demister 10, and preliminary dehumidifying is carried out to air
And drying.Purification air after the processing of demister 10 can be sampled operation before being flowed out from air outlet 9 by air sampling mouth 17,
The content of aerosol, pollutant and moisture after being purified with detection in air.This need to be stopped when the air of sampling can not be up to standard
Plant running, the absorbent solution circulating pump 13 of recycling is driven from absorbent solution floss hole 8 and discharged, discharge behaviour now
Work should close all valves of circulation loop, open the valve of absorbent solution floss hole 8.It can be weighed after absorbent solution is emptied completely
It is new to carry out absorbent solution padding, and repeat above-mentioned washing absorption operation procedure.
The air purified by the present apparatus can remove the aerosol and chemical pollutant of the overwhelming majority well, make this nucleoid
The air of decontamination factory building substantially meets limit value condition of the radgas to environmental emission.The engineering for being actually passed through certain nuclear power station should
Show that contamination is far below limited value of discharge standard with the sampling analysis to absorbent solution, the chemical pollutant in air is gentle
Sol content significantly reduces after the solution absorption sprayed, can reach emission level.
The great advantage of the present apparatus is simple in construction, and essentially free of maintenance, reliability is high, service life length, structure chi
It is very little to be adjusted according to ventilation to be clean, the processing requirement of big flow ventilating system is disclosure satisfy that, clean-up effect is notable, can
Effectively improve the quality of purification air.
Obviously, those skilled in the art can carry out the essence of various changes and modification without departing from the present invention to the present invention
God and scope.So, if belonging to the model of the claims in the present invention and its equivalent technology to these modifications and variations of the present invention
Within enclosing, then the present invention is also intended to comprising including these changes and modification.Above-mentioned embodiment is illustrating to the present invention
Bright, the present invention can also be implemented with other ad hoc fashions or other particular forms, without departing from idea of the invention or originally
Matter feature.Therefore, it is regarded as from the point of view of the embodiment of description is in terms of any illustrative and non-limiting.The model of the present invention
