Since there is no disclosure of any adjustment means for the water supply and drainage lines, the present invention is unsuitable for use as a water heating device using waste hot water such as the present invention, that is, as a waste water reuse device for public baths and the like.

る。(Function) Since the device of the present invention is configured as described above, the waste water overflowing from the bathroom 11 and other used waste water are collected in the storage tank 12 via the settling tank 36, and the pump 13 As the pump 20 operates, fresh tap water is pumped up to the exhaust line 8 and then fed into the heat exchanger 1 from its upper end, and as the pump 20 operates, fresh tap water is pumped from the water tank 16 to the water supply line 17. It is then sent to the heat exchanger 1 from its lower end. Therefore, in the heat exchanger 1, the discharged hot water swirls and descends through the internal pipe 6, while the tap water swirls and ascends through the external pipe 5, and in this process, the internal pipe 6 The required heat exchange is performed through the wall, and tap water, that is, hot water whose temperature has been increased by the heat exchange, is supplied to the boiler 10 and the bathroom 11 via the hot water supply line 7, and conversely, by the heat exchange, The waste water whose temperature has decreased is discharged to the sewer through the drainage line 18. At this time, in the heat exchange pipe 4, the surface area of the internal pipe 6, that is, the heat exchange area is larger than the cross-sectional area of the tap water flowing through the external pipe 5, and the heat exchange pipe 4 is arranged in a spiral shape with multiple sections. Because the pipe length is long (that is, the heat exchange time is long) due to the structure, the heat exchange rate is high.

In order to avoid the inconvenience of the pipe being damaged by internal pressure and the discharged hot water mixing with the tap water in the external pipe 5, the water pressure of the tap water is made higher than the discharged hot water pressure. Specifically, this adjustment is carried out by using the pressure regulating valves 15, 22 while watching the pressure gauges 26, 27.
In each line 8, 17, a certain amount of waste water and tap water discharged from the respective pumps 13, 20 is regulated by the pressure regulating valves 15, 22. Only the flow rate that has been removed is sent to the heat exchanger 1, and the remaining waste water and tap water are returned to the storage tank 12 and water storage tank 16 via bypass lines 14 and 21, respectively.
