Description

Collecting device for waste heat discharged to sewer.

The present invention aims at recovering the waste heat source by obtaining clean hot water from the hot-tempered waste water discharged from a bathhouse, a business office, or a hot-water utilization workplace to a sewer.

In the conventional waste heat recovery apparatus, a cold water pipe is installed in a hot water furnace or a hot water discharge pipe to prevent the freezing of the supply pipe or to supplement the preheating energy of the water by preheating the cold water supplied using a simple heat transfer effect. This complexity does not seem to have the greatest effect.

In the present invention, a warmth-keeping tank is installed in the passage for the sewer, and a hot water tank and a cold water tank are installed on the tank to overlap with each other. Then, the high temperature on the side of the waste water tank is arranged as a heat- To the upper side with a high effect, and the heated ascending heat is heated to warm the cold upper side, and the cold water pipe passing therethrough is heated to effectively obtain and reduce the waste heat.

Description of the Related Art [0002]

1: Wastewater pipe 2: Heated tank 3: Reservoir tank

4: inserting step 5: heat-dissipating shaft 6: water supply pipe

7: Drain pipe 8: Supporting end 9: Discharge tube

A separate water storage tank 3 is disposed on a hot water tank 2 connected to a waste water pipe 1 of a sewer and a superconducting water The heat transfer shaft 5 penetrates into the water storage tank 3 and the heat of the heat transfer shaft 5 heated by the high temperature water flowing into the water storage tank 3 from the water discharge pipe 1 is supplied to the water supply pipe 6 The water in the water storage tank 3 is warmed in the course of discharging the water discharge pipe 7 from the water storage tank 3 through the water storage tank 3 and eventually the heat of the water discharge pipe 1 of the sewage pipe is transferred to the heat storage tank 2 The supporting end 8 is installed at the intermediate side of the heating tank 2 as shown in FIG. 3, and the heating shaft 5 is inserted Cooled water pipe 6 is directly passed between the upper side of the heating tank 2 and heated to the high temperature water in the heating tank 2, To obtain clean hot water.

The heat transfer shaft 5 used in the present invention is made of a general thermally conductive material and is filled with a heat-transfer gas in a vacuum state. When the heat-transfer shaft 5 is heated from the lower end side, the built- Since the heat transfer shaft or the copper pipe is inserted into the hot water waste pipe discharged from the bathroom or the office or workplace using the property of transferring the heat to the upper side, the hot water transferred to the upper side of the heat transfer shaft or hot pipe is used to heat the cold water. It is an economical design that is used as clean hot water or heating water.

Claims (2)

The heat transfer shaft 5 is inserted into the insert plate 4 disposed on the inner surface of the high temperature tank 2 connected to the waste water pipe 1 of the sewer so that the upper part of the water storage tank 3 And the water in the low-temperature tank is heated. The hot water supply system according to claim 1, characterized in that hot water is passed through the hot water tank (2) through the water pipe (1) and the heating shaft (5) And a heat effect of the water supply pipe (6) is obtained simultaneously with heating.
