ABSTRACT:
A treating facility for treating sintering waste gas comprises a first electric dust collector receiving the waste gas and a main blower connected to the first dust collector for moving the waste gas through the first dust collector. A heat exchanger is coupled to receive the waste gas from the blower. A waste gas purifying device is coupled to the heat exchanger for purifying the waste gas discharged from the first dust collector. A second wet electric dust collector is coupled to receive the waste gas from the purifying device and a pressure riser is coupled to the second dust collector for raising the pressure of the output gas of the second dust collector. The output gas from the pressure riser is returned to the heat exchanger and after heat exchange with the gas discharged from the blower is exhausted to atmosphere. A pressure adjusting valve coupled to the exhaust or output side of the main blower, is ordinarily closed but opens to exhaust the gas to atmosphere when an abnormal temperature or pressure exists downstream of the blower.
