  • SLUDGE PROCESSING EQUIPMENT
    Publication number: 20150336832
    Abstract: A sludge processing equipment includes a separation set, a mixer, a blower and a heat recovery unit. The mixer includes a mixing chamber, a feeder and an air compressor. The mixing chamber is communicated with the separation set. The feeder is configured to deliver a sludge into the mixing chamber. The air compressor is configured to provide a first compressed air to the feeder. The air compressor generates a wasted heat during operation. The blower is configured to provide a transporting airflow to the mixing chamber, so as to deliver the sludge to the separation set. The heat recovery unit is configured to deliver the wasted heat generated by the air compressor to the transporting airflow.
