Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, but protection scope of the present invention be not limited to it is following
The range of described specific embodiment.
Referring to Fig.1-4, a kind of Novel tunnel spray dust-reducing system, including sensor of dust concentration 1, infrared induction probe 2,
Buzzer siren 3, water pipe 4, air hose 5, electrical ball valve 6, Main Control Tank 7, dust suppressant addition pump 8, Venturi tube 9, depositing dust branch pipe 10,
Wash away branch pipe 11, spraying device 12.
As shown in Fig. 2, above-mentioned apparatus includes monitoring modular, signal processing module and signal output module, monitoring modular with
For dust concentration as monitoring object to determine whether switch is spraying, device enters signal processing module after obtaining data, then
Information is sent into corresponding main control singlechip circuit and carries out data analysis, is carried out 1 monitoring data of sensor of dust concentration by algorithm
Integration processing, if being more than setting early warning value, carrying out buzzing alarm and opening spraying.When work, sensor of dust concentration 1 is to lane
Dust concentration in road carries out real-time monitoring, sends a signal to Main Control Tank 7 by electric wire, and the information that Main Control Tank 7 receives is sent
To main control singlechip circuit carry out data analysis, then the early warning value of the result of monitoring modular and setting is compared and analyzed and
Classification, generates corresponding abnormity early warning information, warning information is sent to control room on well, and buzzer siren 3 sounds the alarm,
Neighbouring personnel are reminded.
Main Control Tank 7 is equipped with timing opening apparatus, and setting per tour previous hour automatically turns on depositing dust branch pipe 10 and washes away branch pipe
11 electrical ball valve 6 carries out daily atomizing de-dusting and rinses lane side.Dust in 1 real-time monitoring tunnel of sensor of dust concentration is dense
Degree reaches Main Control Tank 7, records data by Main Control Tank 7 and uploads to control room on well, when dust concentration is higher than early warning value in tunnel,
Main Control Tank 7 issues the electrical ball valve 6 that signal opens air hose 5, water pipe 4 and depositing dust branch pipe, opens dust suppressant addition pump 8, passes through text
Modified high-pressure atomization water mist is sprayed at drift section by spraying device 12 by venturi 9.Main Control Tank 7 issues alarm simultaneously
On the one hand signal opens buzzer siren 3, remind drift section personnel nearby, alarm signal is on the other hand reached well up-regulation
Room is spent, early warning value is lower than by the tunnel dust concentration after atomizing de-dusting, closes electrical ball valve 6 and dust suppressant addition pump 8 immediately,
Stop being sprayed for drift section.If dust concentration is persistently higher than early warning value and is reached by the control room person of sending someone on well within an hour
The tunnel reduces dust concentration using other depositing dust methods；When infrared induction probe 2 monitors that someone or mine car pass through, Main Control Tank
7, which issue signals, stops spraying, and personnel and mine car continue spraying after passing through.Can depositing dust and the tunnel length washed away as needed, lead to
It crosses threeway 15 and connects multiple rows of spraying device 12.The spray head 13 of flush pipe road can be adjusted the angle according to specific section configuration, make to rush
The range of brush lane side is bigger, achievees the purpose that section spraying depositing dust and washes away lane side.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
