The invention discloses an energy-saving recycling
combination system for industrial circulating cooling water. The
system comprises two circulating cooling water systems, namely, a sealed-type circulating cooling water
system and an open-type circulating cooling water
system and specifically comprises a cold water tank, a
water treatment process device, a cooling
water supply pump, a
pressure sensor, a flow sensor, a cooled device, an intermediate water tank, a lift pump, a
cooling tower, a
heat pump set, a hot water tank, a liquid-
level sensor and an electronically controlled device and is an energy-saving and water-saving optimized
combination system for industrial circulating cooling water. Serial-type
water supply is adopted in the sealed-type circulating cooling water system, parallel-type
water supply is adopted in the open-type circulating cooling water system, the
utilization rate of the cooling water is increased to a maximize extent and the water supply amount of the cooling water is decreased. Since the system is provided with the
water treatment process device, the
water quality of the circulating water is improved, the
sewage discharge capacity is decreased and the concentration multiple of the circulating water is increased. By arranging the
heat pump set in the system, the low-temperature
waste heat of the return water of the cooling water is effectively recovered, the
evaporation amount is reduced and the effective utilization of the heat source is achieved and the system has important practical values.
