초록 ▼

A holding tank receives waste water from a dishwasher or laundry machine having a rinse cycle and at least one wash cycle. A pump moves the waste water through a heat exchanger at the same time that the rinse cycle requires hot water from a hot water heater. The cold water feed for the hot water heater is also passed in countercurrent heat exchange relationship with the waste water to provide warmed or heated makeup water at the same time that hot water is being withdrawn therefrom. The cooled waste water from the heat exchanger may be collected in a tank and supplied to any one or more of several additional devices, such as a water cooled refrigerant compressor, a grease extraction ventilator having water contact means, a waste food grinder, etc. The ventilator and compressor may also be placed in series, while the cooling water heated in the compressor is recirculated to the heat exchanger. The holding tank may be mounted directly beneath the dishwasher, or the holding tank and countercurrent heat exchanger may be placed in a common housing, with the holding tank beneath the heat exchanger and a pump to transfer the waste water from the holding tank to the appropriate tubes of the coils of the heat exchanger, from which waste water may be discharged into a discharge area adjacent the holding tank. A removable screen for the waste water may be provided above the holding tank in each instance. When a discharge area is adjacent the holding tank, the screen will be self-cleaning, due to flow of incoming waste water across the screen and into the discharge area, when the screen is occluded.

Apparatus for energy recovery for a device using heated liquid from a liquid heater and producing waste liquid, comprising: a holding tank for collecting and releasing said waste liquid; an elongated outlet, adjacent said holding tank and into which waste liquid from said holding tank may overflow; upright baffle means separating said holding tank from said outlet; a generally horizontal screen disposed above the normal liquid level in said holding tank through which waste liquid normally flows but adapted to permit waste liquid to overflow into said outlet to carry material into said outlet which retards flow through said screen; an inlet for said waste liquid generally opposite to said outlet so that liquid from said inlet will carry material clogging said screen into said outlet; means for transferring waste liquid from said holding tank to a heat exchanger to preheat incoming liquid for use in said device; means for transferring said preheated liquid to means for heating said preheated liquid to a temperature sufficient for use in said device; and means for transferring waste liquid from said heat exchanger to an outlet. An apparatus for energy recovery for a dishwasher using heated water from a hot water heater, said dishwasher having separate rinse and wash cycles with said rinse cycle receiving heated water from said hot water heater and said wash cycle producing waste water, comprising: a holding tank for collecting and releasing said waste water, said holding tank having a capacity generally equal to the amount of waste water received from said wash cycle; means for transferring waste water from said holding tank to a heat exchanger to preheat incoming water for use in said dishwasher; means including pump means for transferring said preheated water directly to said hot water heater for heating said preheated water to a temperature sufficient for use in said dishwasher; means for controlling the transfer of waste water to said heat exchanger at a time corresponding to the flow of heated water from said hot water heater to said dishwasher, said control means being responsive to the level of waste water in said holding tank reaching a predetermined level for starting said pump and a predetermined lower level for stopping said pump when said waste water has been drawn down to said lower level; and means for transferring waste water from said heat exchanger to an outlet.
