Research on design and application of spray dust removal system for coal mine driving face
The traditional spray dust suppression system uses a spray type device to spray dust to make the air carry away the dust.The dust diffuses to the working area,but the dust reduction rate is uneven.Therefore,the design and application practice of spray dust re-duction system in the driving face of coal mine were studied.In the hardware design of the system,dust sensors and infrared sensors are added,and the low-pressure spray pump is replaced by the high-pressure spray pump;in terms of software design,the dust sensor is used to monitor the concentration of coal mine dust,obtain dust data in real time,determine spray parameters,dynamically adjust the nozzle points in combination with spray parameters,spray water mist into the air by spraying device,so that the dust can be wetted,con-densed and precipitated,and remove dust.Through the above design,the spray dust suppression system of coal mine driving face is com-pleted.The practice results showed that:17 intelligent spray points were set up,and five sampling points of No.201 and No.109 working faces were selected for measurement respectively.The dust concentration at the sampling points was significantly reduced,and the dust fall rate can reach about 40％,making the dust fall rate in each area even.
