Abstract
It the utility model is related to a kind of tunnel construction sprinkling dust-removing device, especially wet method device for reducing dust.It includes casing, water system, spray system and waste water recovery system, casing includes rigid support, seal closure is covered with rigid support, water system is installed on casing, water system connects spray system, spray system is located at casing top inwall, is gutter below casing, and the import of casing connects negative pressure axial flow blower.The utility model sets sprinkling dust-removing device outside tunnel portal, the import connection negative pressure axial flow blower of sprinkling dust-removing device, the dusty gas in tunnel is pumped into device using negative pressure axial flow blower and carries out spray dust's processing.Dust processing in hole and qualified discharge problem when can effectively solve the dust pollution in tunnel construction and can not use wet type dust-removing method because formation geology is bad, country rock meets the water easily reason such as softening; ensure that the air quality in hole reaches occupational health Con trolling index requirement; atmospheric environment is simultaneously effective protected, avoids having an impact nearby residents life.
Description
Technical field
It the utility model is related to a kind of tunnel construction device for reducing dust, especially wet method device for reducing dust.
Background technology
In tunnel construction, development machine excavate caused by one of a large amount of ground dust an important factor for being atmosphere pollution, simultaneously
Also the health and safety of job site personnel is directly endangered, the dust pollution of construction area must be reduced for this.It is domestic at present
Tunnel excavation use brill is quick-fried or tunneler construction method, coordinate wet drilling and spraying to control dust mostly, it is this
The shortcomings of depositing dust mode is there is humid environment and dust-laying effect difference in hole is easily made, especially when running into, formation geology is bad, encloses
When rock meets the situation that water easily softens, the use of wet type depositing dust method is limited.It is therefore desirable to provide one kind to improve tunnel
Interior construction environment and the good tunnel device for reducing dust of dust-laying effect.
The content of the invention
Problem to be solved in the utility model is insufficient aiming at more than and providing one kind can effectively solve in tunnel construction
In, dust processing when can not use wet type dust-removing method because formation geology is bad, country rock meets the water easily reason such as softening in hole
With the device for reducing dust of qualified discharge problem.Its technical scheme is as follows：
It includes casing, water system, spray system and waste water recovery system, and casing includes rigid support, rigid support
On be covered with seal closure, water system is installed on casing, water system connection spray system, spray system is located in casing top
Wall, casing lower section are gutters, and the import of casing connects negative pressure axial flow blower.
The water system includes elevated tank and high-pressure water pipe, and high-pressure water pipe connects water main, spray is installed on water main
Head is drenched, water main and spray head form spray system.
The gutter connects sedimentation basin.
The casing afterbody sets air outlet, and geomembrane is set on the inside of air outlet.
Compared with prior art, the utility model has an advantageous effect in that：
Sprinkling dust-removing device is set outside tunnel portal, the import connection negative pressure axial flow blower of sprinkling dust-removing device, utilized
Dusty gas in tunnel is pumped into device and carries out spray dust's processing by negative pressure axial flow blower.Effectively can solve in tunnel construction
Dust pollution and because formation geology is bad, country rock is met when water easily softening etc. can not use wet type dust-removing method reason in hole
Dust processing and qualified discharge problem, it is ensured that the air quality in hole reaches occupational health Con trolling index requirement, simultaneously effective
Atmospheric environment is protected, avoids having an impact nearby residents life.
Brief description of the drawings
Fig. 1, it is the utility model structure diagram.
Embodiment
Referring to Fig. 1, the utility model includes casing, water system, spray system and waste water recovery system.Casing includes firm
Property support 1, seal closure 2 is covered with rigid support 1；Water system is installed on casing, water system includes the height that eminence is set
Position water tank 5 and high-pressure water pipe 6, high-pressure water pipe 6 connect water main 9, spray head 10, water main 9 and spray head are installed on water main 9
10 form spray system, are flowed out by spray head 10 and form spraying, and spray system is located at casing top inwall；The ground in casing
Middle part sets gutter 13 along casing axis direction, and gutter 13 connects sedimentation basin 14, and gutter 13 and sedimentation basin 14 form dirt
Water reclamation system, the both sides ground of gutter 13 is slightly higher, when the sewage that dust and shower water combine to form falls when on casing ground,
Sewage self-flowing imports gutter 13, is recycled after gutter 13 flow in sedimentation basin 14 and precipitated；The rigidity branch of casing
Frame 1 is firmly connected with blower bracket 12, and negative pressure axial flow blower 11 is installed on blower bracket 12, using negative pressure axial flow blower 11 by tunnel
Dusty gas in hole, which is pumped into device, carries out spray dust's processing.
Booster water pump 8 is set up in high-pressure water pipe 6, in case being used during insufficient pressure.
Valve 7 is also installed in high-pressure water pipe 6, water spray is controlled by valve 7.
Pressure energy to ensure in casing is discharged in time, sets air outlet 3 in casing afterbody, the inner side of air outlet 3 sets soil
Work film 4 carries out dust-filtering, to prevent flour dust overflow.
