Abstract
Present invention relates particularly to tower coal bunker dust falling system.Including main jet spray pipe, multiple annular auxiliary spray header, multiple dust density detectors and controllers, the multiple dust density detector is arranged at coal bunker inner wall and vertically even portion, the main jet spray pipe is vertically arranged in coal bunker, multiple annular auxiliary spray headers are axially disposed in coal bunker and are connected by main jet spray pipe, multiple high-pressure water nozzles are set on main jet spray pipe, multiple spray apertures are set on annular auxiliary spray header, the multiple dust density detector and multiple high-pressure water nozzles are connected with controller respectively.When coal pours into coal bunker, the dust concentration difference of different height is very big in coal bunker, in the technical program, the dust concentration of different height in multiple dust detector real time monitoring coal bunkers, the high-pressure water nozzle for triggering corresponding height forms water mist, and water utilization rate is high, energy conservation and environmental protection.
Description
Technical field
The invention belongs to mineral engineering field, and in particular to tower coal bunker dust falling system.
Background technology
Currently, the coal newly adopted usually is pre-stored in shaft coal pocket by underground coal mining, ground is transported to when reaching a certain amount of, so
And in the coal bunker of relative closure, since toppling over for coal can produce substantial amounts of dust, up to 50000mg/m sometimes3, such as electricity
Spark or underground electrical leakage, it is likely that explosion occurs and destroys coal bunker, consequence is hardly imaginable, explosion-suppressing method currently on the market
Mainly for the processing after explosion, such hysteresis quality brings very big security risk to underground site operation.
The content of the invention
The purpose of the present invention is：Tower coal bunker dust falling system is provided, to overcome it is above-mentioned in the prior art the defects of.
The adopted technical solution is that：
Tower coal bunker dust falling system, it is characterized in that：Including main jet spray pipe, it is multiple annular auxiliary spray header,
Multiple dust density detectors and controller, the multiple dust density detector are arranged at coal bunker inner wall and vertically even
Portion, the main jet spray pipe are vertically arranged in coal bunker, and multiple annular auxiliary spray headers are axially disposed in coal bunker and lead to
The connection of main jet spray pipe is crossed, multiple high-pressure water nozzles are set on main jet spray pipe, multiple sprays are set on annular auxiliary spray header
Hole is drenched, the multiple dust density detector and multiple high-pressure water nozzles are connected with controller respectively.
Further, from top to bottom radius gradually increases the multiple annular auxiliary spray header.
Further, a plurality of straight slot is radially set on the annular auxiliary spray header, the spray apertures are arranged on straight slot
It is interior.
Further, multiple flushing bend pipes certainly that Open Side Down are set on the main jet spray pipe, are set from rinsing on bend pipe
Radio magnet valve is put, the radio magnet valve is connected with controller.
Further, the spacing of adjacent annular auxiliary spray header is from top to bottom gradually reduced.
Further, the high-pressure water nozzle uses injection type secondary atomized spray head.
The beneficial effects of the invention are as follows：When coal pours into coal bunker, the dust concentration difference of different height is very big in coal bunker,
In the technical program, multiple dust detectors monitor the dust concentration of different height in coal bunkers in real time, trigger the height of corresponding height
Sprinkler head is pressed to form water mist, water utilization rate is high, energy conservation and environmental protection, meanwhile, auxiliary spray header further ensures that spraying effect.
From rinse bend pipe can periodic flushing main jet spray pipe, prevent from blocking.

Embodiment
Below in conjunction with the attached drawing of the present invention, technical scheme is clearly and completely described.Based on this hair
Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained without creative efforts
Example, belongs to the scope of protection of the invention.
As Figure 1-Figure 4, the present embodiment provides a kind of tower coal bunker dust falling system, including 1,3 ring of main jet spray pipe
Shape aids in spray header 2,3 dust density detectors 3 and controllers, and 3 dust density detectors 3 are arranged at 4 inner wall of coal bunker
And vertically even portion, main jet spray pipe 1 are vertically arranged in coal bunker 4,3 annular auxiliary spray headers 2 are axially disposed
Connected in coal bunker 4 and by main jet spray pipe 1,3 high-pressure water nozzles 5, annular auxiliary shower water are set on main jet spray pipe 1
Multiple spray apertures 6 are set on pipe 2, and multiple dust density detectors 3 and multiple high-pressure water nozzles 5 are connected with controller respectively.
From top to bottom radius gradually increases by 3 annular auxiliary spray headers 2.Radially set on annular auxiliary spray header 2
A plurality of straight slot 7, spray apertures 6 are arranged in straight slot 7.Multiple flushing bend pipes 8 certainly that Open Side Down are set on main jet spray pipe 1, from
Rinse and radio magnet valve 9 is set on bend pipe 8, radio magnet valve 9 is connected with controller.Between adjacent annular auxiliary spray header 2
It is gradually reduced away from from top to bottom.High-pressure water nozzle 5 uses injection type secondary atomized spray head.
During work, each dust density detector is formed by controller and level high-pressure water nozzle to be fed back, and is visited
When the dust concentration of survey is higher than predetermined threshold, start corresponding high-pressure water nozzle, otherwise close, meanwhile, auxiliary spray header is protected
Normally open is held, controller is periodically opened from the radio magnet valve rinsed on bend pipe and rinses main jet spray pipe.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
