The invention discloses a
drying calcining
treatment system of drilling well waste mud. The
system comprises a rotary type
drying calcining device, a rotary driving mechanism and a rotary support mechanism, wherein the rotary type
drying calcining device passes through the rotary driving mechanism and the rotary support mechanism, the drying end of the rotary type drying calcining device is provided with a
raw material feeding
system and a drying heat-supplying device, the calcining end of the rotary type drying calcining device is provided with a pulverized
coal burner and a
screw conveyor, the rotary type drying calcining device is inclined, the drying end is higher than the calcining end, the gas outlet of the drying heat-supplying device is connected with the hot wind inlet of the rotary type drying calcining device, the burning end of the pulverized
coal burner extends into the calcining end, and the middle part of the rotary type drying calcining device is connected with a dust removal purification
system. The system is quick, high efficient, convenient and low dissipative, the treatment of the drilling well waste mud does not need the
secondary treatment, the treated ultimate products can be used as recycling materials and the
pollution problem of the drilling well waste mud is thoroughly solved.
