This utility model discloses a comprehensive
industrial waste heat utilization
system for the liquor
brewing industry. It includes a two-stage high-temperature
heat pump and a
heat exchanger connected to the
process equipment. The two-stage high-temperature
heat pump is connected to a first-stage low-temperature
heat pump, which is connected to the fan coil units of an office building via pipelines, with a water pump II installed on the connecting pipelines. A control valve I and water pump I are connected between the
heat exchanger and the office building's
underfloor heating pipes. A control valve IX is connected between the
process equipment and the
heat exchanger. A
bypass valve is also installed between the
process equipment and the heat exchanger, connecting to a scrubbing
tower.
Control valves are installed at both the front and rear ends of the scrubbing
tower, and a
chimney is connected to the rear of the scrubbing
tower. The process equipment is also connected to the two-stage high-temperature heat pump, with a water pump V connecting them. This utility model utilizes a two-stage heat pump unit to achieve not only cooling of the
plant area but also heating and full-condition operation of the process heat source, realizing the comprehensive recycling and utilization of energy.
