Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model technology.It should be appreciated that specific embodiment described herein is only used to
It explains the utility model, is not used to limit the utility model.
As shown, box tunnel water curtain dust fall device, including depositing dust case 1 and exhaust fan 2, the depositing dust case 1 and exhausting
It is connected between machine 2 by air hose 3, dust laden air can be sent in depositing dust case 1 by exhaust fan 2 by air hose 3；It is set in depositing dust case 1
It is equipped with spray head 13, dust in water spray capture dust laden air can be passed through.
When the device for reducing dust works, exhaust fan 2 is placed in tunnel tunnel face, and depositing dust case 1 is located at outside tunnel face or is located at the palm
In tunnel construction sections behind sub- face.More than 100 meters, maximum can achieve 200 meters for the distance between the exhaust fan 2 and depositing dust case 1.
The depositing dust case 1 is enclosed construction, and is provided with air inlet 11 and air outlet 12, and depositing dust case 1 includes several
Water mist spraying head 13, and the setting being spaced is in inner wall surrounding.
The air inlet 11 and air outlet 12 are located in opposite two end plates, so that dust laden air is in depositing dust case
Formed it is longer, to increase the capture rate to dust.
Water mist spraying head 13 haves three layers along the inner wall setting of depositing dust case, to reinforce the effect of water mist dust-removing.
The lower part of air intake end plate is arranged in the air inlet 11 of the depositing dust case 1, and is located under bottom water mist spraying head 13；
Air outlet 11 is located at the top of opposite side outlet air end end plate.
The depositing dust case 1 further includes drainpipe 14, and the import of the drainpipe 14 is located on 1 mud position of depositing dust case, and position
Under the bottom of air inlet 11.
The bottom plate of the depositing dust case 1 is equipped with the gradient from inlet end towards outlet side, is arranged in the endplate root of inlet end
There is the spray head 17 of removing contamination of removing sludge of the row towards outlet side；The outlet side of bottom plate is provided with sewage pipe 16, for excluding
Precipitating sludge.Generally speaking, the equal slope aspect sewage pipe 16 of the bottom plate of depositing dust case 1 is arranged on sewage pipe 16 so that spoil disposal is more smoothly
There is mud valve, when needing spoil disposal, directly opening mud valve be can be completed, and cooperate spray head 17 of removing contamination, and may make spoil disposal more extra bus
Bottom.
1 both side plate of depositing dust case is staggered to be provided with partition 15, so that air forms the gas of detour from inlet end to end of going out
Road further increases stroke of the air-flow in depositing dust case, increases the probability captured by water mist.The bottom end of partition 15 and drop
Gap 151 is equipped between the bottom plate of dirt case 1, i.e., two pieces of adjacent partitions 15 are separately fixed on both side plate, and with opposite side side plate
With certain spacing, the spacing is not less than the bore of air inlet 11.The presence in gap 151 obtains the precipitating sludge of bottom
To be easily discharged, spoil disposal will not be caused difficult because of partition 15 is provided with.
The air hose 3 is flexible duct, and what is be spaced is fixed in the tunnel wall in tunnel 4 by fixing piece 31.With tunnel
Road is tunneled to depth, constantly lengthens the length of air hose 3, and longest can be lengthened to 200 meters or so, only needs frequently mobile exhausting in this way
Machine 2, and depositing dust case 1 is because volume and weight is bigger, can with the movement of rather low-frequency time, such as with exhaust fan 2 away from
It when from more than 200 meters, then is disposably moved, to reduce the manipulation strength of Field Force.
Water mist spraying head 13 is unified to be connected on water distributor 131, and by water inlet pipe 132 to around water distributor 131
It supplies water.
Depositing dust case 1 is additionally provided with idler wheel 18, is moved in tunnel with facilitating.Further, the depositing dust case 1 of this device for reducing dust
Mountable exhaust fan 2 and air hose 3 can also be accommodated on special-purpose vehicle in the non-use state on special-purpose vehicle, be turned with facilitating
Fortune and operation.
In the present embodiment, depositing dust case 1 is welded using 6mm steel plate, and relevant pipeline uses high-pressure water pipe, water mist spraying head
13 are arranged three rows in cabinet from top to bottom, and every row is arranged 20.When work, face exhaust fan 2 is by the dust laden air in construction
It is pumped in depositing dust case 1 by air hose 3, dust is caught by the water droplets that the three draining fog spray heads 13 that water tank is arranged are sprayed
It obtains, and falls into bottom, dirt mud is deposited to bottom, and supernatant is discharged by sewage pipe 16, and the air by purification is from air outlet 12
Discharge.
The dust removing effects of the present apparatus are significant, and the capture rate of dust can reach 95-97%, have high popularization and application valence
Value.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
