Embodiment
The present invention is described in further details with specific embodiment below, but the present invention is not only limited in detail below in fact
Apply example.
Embodiment
As Figure 1-3, a kind of vent cabinet smoke absorption cleaning system, including purifying box 1, through the purifying box 1
The blast pipe 3 that top plate inserts into the inner the air inlet pipe 2 in portion and connected with the purifying box 1；The outer wall of the air inlet pipe 2 with it is described
It is tightly connected between the top plate of purifying box 1；The end face of the outlet side of air inlet pipe 2 is recessed a cylindricality cavity 2.1, it is described enter
The cavity wall that the outer wall of tracheae 2 surrounds the cylindricality cavity 2.1 forms a cavity 2.2；In the side wall of the cylindricality cavity 2.1 uniformly
Provided with steam vent；The top plate of the purifying box 1 is provided with liquid distribution trough 4 and for by the liquid of the bottom of purifying box 1
It is pumped into the water pump 5 of the liquid distribution trough 4；The bottom of liquid distribution trough 4 is provided with along circumferentially distributed some of the air inlet pipe 2
Outage；Sprayer unit 6 is provided with the cylindricality cavity 2.1；The sprayer unit 6 is by being fixed on the bottom of purifying box 1
Water absorbent cotton core 6.1 and the atomizing piece 6.2 at the top of the water absorbent cotton core 6.1 form；Set on the roof of the cylindricality cavity 2.1
There is rounding vertebra shape projection 2.3；The rounding vertebra shape projection 2.3 is coaxial with the atomizing piece 6.2；The bottom of the purifying box 1 is set
There is the mandruka that upper surface is bonded with the opening of the cylindricality cavity 2.1；The purifying box 1 is sealed by upper and lower two parts and fastened
Form；The air inlet pipe 2 connects with vent cabinet；The blast pipe 3 is located at the top of the purifying box 1, is set on the blast pipe 3
There is air exhauster 7.
Middle part but the atomizing piece of the cylindricality cavity 2.1 are stretched into the one end of the water absorbent cotton core 6.1 provided with atomizing piece 6.2
6.2 do not contact with the rounding vertebra shape projection 2.3.
The liquid distribution trough 4 is stacked gradually by several coaxial annular grooves 4.1 and formed；The annular groove being coaxially distributed
4.1 bottom is flushed, and the height of the annular groove 4.1 is sequentially reduced from the inner to the outer.
The top plate of the inwall and the purifying box 1 of the annular groove 4.1 of the innermost layer of liquid distribution trough 4 is fixed.
The bottom of annular groove 4.1 of the liquid distribution trough 4 is circumferentially uniformly provided with outage.
The input pipe of the water pump 5 extends the bottom of purifying box 1, and efferent duct extends the innermost layer of liquid distribution trough 4
Annular groove 4.1 in.
The mandruka thickness is 1st/1st to three/5th of the height of purifying box 1.
Gap is left between the side wall of the liquid distribution trough 4 and the purifying box 1.
Illustrate the principle of the present invention exemplified by below using water as absorbing liquid, the present invention in purifying box 1 in use, note first
Enter the water that water level is mandruka thickness half, then open water pump 5, atomizing piece 6.2, the power supply of air exhauster 7；In vent cabinet
Flue gas enter air inlet pipe 2 after discharged from the steam vent of the side wall of cylindricality cavity 2.1, due to the row of the cylindricality cavity 2.1
Stomata is uniformly distributed around the atomizing piece 6.2；Therefore speed can be cancelled out each other so that flue gas can be with atomization after gas discharge
The fog that piece 6.2 is atomized has the sufficient time uniformly to mix, and most of flue gas has the sufficient time to be adsorbed by fog, without
Adsorption effect is influenceed because exhaust velocity is too fast, remaining flue gas and the fog of flue gas has been adsorbed and continues towards the cylindricality cavity
2.1 outlet is overflowed, into the duct of mandruka in continue contact with water in hole and be adsorbed, most of flue gas is brought into again
In water, the flue gas that residue is overflowed is with fog during being moved towards blast pipe 3, it is necessary to is sprayed by the liquid distribution trough 4
Cylindrical spraying zone, by remaining fog and scolding tin flue gas drench in water enter mandruka in；Air after purification passes through again
Blast pipe 3 is discharged, without influenceing air quality in can directly emptying；The effect of rounding vertebra shape projection 2.3 of the present invention is mist
Changing the fog that piece 6.2 sprays can converge thereon after the condensation of the roof of cylindricality cavity 2.1 and constantly be dropped in the center of atomizing piece 6.2
Continue to be atomized piece 6.2 and utilize, reach ringing, and solubility of the flue gas in fog can be increased.
It the above is only the feature implementation example of the present invention, the scope of the present invention be not limited in any way.It is all to use together
The technical scheme formed Deng exchange or equivalence replacement, all falls within rights protection scope of the present invention.
