WASTE THERMAL DECOMPOSITION TREATMENT DEVICE AND CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To prevent leak of thermally decomposition gas to the outside caused by sudden rise of gas pressure of a thermal decomposition device in the event of a failure while enabling stable burning of a thermal decomposition gas combustion device. SOLUTION: The waste thermal decomposition treatment device comprises: the thermal decomposition device 2 for thermally decomposing wastes into the thermal decomposition gas and a thermal decomposition residue; the thermal decomposition gas combustion device 3 for burning the thermal decomposition gas and supplying the resulting combustion exhaust gas to the thermal decomposition device 2 to heat the wastes in the thermal decomposition device; induced blowers F1 and F2 for inducing combustion exhaust gas after heating the waste; pressure sensors S1 and S2 for detecting a first gas pressure P1 in the thermal decomposition device and a second gas pressure P2 in the thermal decomposition gas combustion device; and a control device D for controlling the induced blowers. The control device controls the induced blowing quantity of the induced blowers, based on the first gas pressure. A plurality of the induced blowers are preferably set in parallel or in series.
