Detailed Description
Feature
Mainly used in the coal mine coal chute, coal bunker, coal and other places of transfer point when the coal produced by coal dust, spray water spraying dust, clean air environment
By the master control box, electric ball valves, dust concentration sensor, heat release optical sensors, output in the main box electric dust concentration sensor and pyroelectric optical sensors and electric ball valve
Working status of dust sensors use a room according to the requirements set arbitrary dust concentration alarm value, when it comes to an alarm value for measuring the dust density, dust concentration sensor output alarm signal to the main control box, main box through the preset program control electric ball valve open spray dust,
when the dust concentration is lower than the sensor set alarm value electric ball valve shut down automatically to stop the spray, dust in transfinite spray dust fall out of fashion, when there are pedestrians or vehicles through, installed on the spray area of lee lane heat-release optical sensor detection to the human body heat release signals and mobile, spray will automatically stop spraying automatic recovery after spray or car.
ZPC - 127 mining the characteristics of automatic water spraying dust device.
