  • Treating facility for sintering waste gas
    Patent number: 4187085
    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.
