Hot -blast and coal slime drying control system of high temperature is prepared in colliery low concentration gas oxidation

The utility model relates to a hot -blast and coal slime drying control system of high temperature is prepared in colliery low concentration gas oxidation, hot -blast subsystem of high temperature and safe chain control subsystem are produced in air distribution subsystem of low concentration gas, the oxidation of gas heat adverse current including connecting gradually, air distribution subsystem of low concentration gas adopt the gas pipeline and install in proper order and taking out combined type spark arrester on adopting the gas pipeline, air distribution machine, methane consistency transmitter including taking out, gas heat against the current the oxidation prepare the hot -blast subsystem of high temperature and include mixing controller, oxidation unit forced draught blower, heat oxidation unit against the current, the chain control of safety subsystem including installing material sensor, the temperature sensor who installs at the drying drum entry on coal slime material loading machine, installing pressure sensor on the pipeline is given vent to anger to low temperature, installing at heat oxidation unit high temperature hot air exitus's high temperature governing valve and controller against the current. Compared with the prior art, the utility model has the advantages of the security is high.
