Specific implementation mode
A kind of specific embodiment of the proposition present invention as shown in Figure 1, a kind of blowing and drawing type dust pelletizing system of the underground space, including
The top of the underground space 1, the underground space 1 is equipped with several air outlets 2, and the quantity of air outlet 2 can be according to the underground space 1
Size reasonable is arranged, and air blowing hood 2-1 is additionally provided at air outlet 2, improves the intensity into 1 wind-force of the underground space, the air outlet 2
Be respectively connected with ajutage 3, the ajutage 3 is equipped with the wind turbine 4 for blowing to the underground space 1, the underground space 1 and away from
It is equipped with several inlet scoops 5, the suspended hood 5-1 on inlet scoop 5, and the quantity of inlet scoop 5 from the side of air outlet 2 farther out
It is corresponding with the quantity of air outlet 2, air-flow stream identical with 1 airflow direction of the underground space is formed between air outlet 2, inlet scoop 5
To even the underground space 1 is air-flow clockwise, then setting forms air-flow clockwise between air outlet 2, inlet scoop 5, if underground is empty
Between 1 be air-flow counterclockwise, then between air outlet 2, inlet scoop 5 setting form air-flow counterclockwise, the inlet scoop 5 is respectively connected with suction
Air hose 6 is equipped with the first suction ventilator 7 for drawing underground space turbid air on the aspiration channel 6, the aspiration channel 6
End connects dirt pocket 8, and the front side on 8 top of the dirt pocket is equipped with multiple spray nozzles 9, rear side is connected with exhaust duct 10, sprays
The quantity of atomizing nozzle 9 is according to the size of the underground space 1 and the scientific and reasonable setting of the flow of gas, the i.e. underground space 1 and gas
The flow of body is big, then the quantity setting of spray nozzle 9 is more, and vice versa, the water system of the spray nozzle 9 and high pressure
It connects, the second suction ventilator 11, air purifier 16 is successively equipped on the exhaust duct 10, the lower end of the dirt pocket 8 is connected with
Drainpipe 12, the wind turbine 4, the first suction ventilator 7, the second suction ventilator 11, air purifier 16 are connect with driving device.
The rear end of the drainpipe 12 be equipped with grey water system 13, and the front end of drainpipe 12 successively be equipped with may filter that volume compared with
Strainer 14, the gate valve 15 for opening and closing drainpipe 12 of big impurity, after grey water system 13 carries out processing up to standard to sewage,
Spray nozzle 9 can be given to supply water, the occasion of other undrinkable water can also be connected, achieved the purpose that recycle sewage, avoid
Environmental protection and energy saving are realized in the waste of water resource.
The aspiration channel 6 and the connector setting of dirt pocket 8 are in horn-like structure, and horn mouth is connect with dirt pocket 8, is protected
The connection of card dirt pocket 8 and aspiration channel 6 is inclined, and inclined angle is preferably provided greatly a bit, effectively prevent impurity in air
After squirting, generation reaction force flows back into aspiration channel 6 and enters in the underground space 1, influences dust removing effects.
The 45 ° of settings diagonally downward windward of the spray nozzle 9, i.e. spray nozzle 9 are tilted to the left downward 45 ° and are arranged, water particle
Contact effect of the dust with water particle is decide with the relative velocity of grit, and the more high then kinetic energy of water particle speed is bigger, is contacted with grit
Dust is moistened and is captured by the surface tension for being conducive to overcome water, and 45 ° of settings diagonally downward increase the speed relatively of water particle and grit
Degree, to which the covering section range of the sprinkling of spray nozzle 9 is wide, good dedusting effect.
The aperture setting of aperture≤1mm of the spray nozzle 9, firm discharge, spray nozzle 9 are smaller, and spray nozzle 9 is got over
Energy high pressure spray goes out water mist, expands the dispersion degree of water mist and increases the relative velocity of water mist and grit, is conducive to improve dust removing effects.
The air outlet 2 is arranged diagonally downward, and with angle of inclination≤45 ° of vertical direction, the different underground spaces 1 is high
To spend different, difference should be also arranged in the angle of inclination of air outlet 2 and vertical direction, if the height of the underground space 1 is relatively low, air outlet
2 is bigger than normal with the angle of inclination setting of vertical direction, if the height of the underground space 1 is higher, air outlet 2 inclines with vertical direction
Rake angle setting is less than normal, effectively avoids the dust raising phenomenon on 1 ground of the underground space, while ensureing the wind entered from air outlet 2
Area covers the entire underground space 1, good dedusting effect as far as possible.
First suction ventilator 7 is set as powerful air-suction fan, and the attraction of powerful air-suction fan is high, ensures absorption ground as far as possible
All turbid airs of down space 1, it is ensured that the air of the underground space 1 effectively exchanges, while greatly improving dust removing effects.
The wind turbine 4 is that low-noise fan will produce noise, especially night, low-noise fan when wind turbine 4 is run
It avoids generating the larger noise of decibel, prevents a series of generation of bad phenomenons.
When the present invention uses：In the underground space 1, most dust deposit on the ground, with impurity such as dust in air,
Start blowing and drawing type dust pelletizing system, wind turbine 4 is blown to the underground space 1, and the joint that blowing-suction type air-stream is constituted in conjunction with the first suction ventilator 7 is made
With, dust is blown near wind inlet 5, then by the first suction ventilator 7 by after dust inspiration aspiration channel 6, into dirt pocket 8,
Spraying nozzle 9 sprays high-pressure water mist and is contacted with dust, to by the impurity such as dust moistening, the impurity of moistening due to gravity,
8 bottom of dirt pocket is fallen into, since the dust of inspiration can not possibly all be drenched by water mist, some dirty air exists,
The air of this part dirt is removed by the absorption of the second suction ventilator 11 into after exhaust duct 10, then by the purification of air purifier 16
Miscellaneous to be discharged to outdoor, the sewage in trash chamber 8, which is entered after filter screen 14 in grey water system 13, to be handled, the non-drink after processing is qualified
It can be used to supply water to spray nozzle 9 or be supplied for other, the working condition chart run as shown in Figure 2 with water.Lock on drainpipe 12
Valve 15 often it is in the open state, if strainer 14 blocks, can closing gate valve 15, clean out strainer 14 and reopen again.
Certainly, only the preferred embodiments of the disclosure is described in detail in conjunction with attached drawing above, not with this
Limit the practical range of the present invention, equivalence changes made by all principles under this invention, construction and structure should all be covered by this
In the protection domain of invention.
