[0002] The existing heating technology mainly heats the heat medium through the heat source and then heats the air to increase the ambient temperature after heat exchange. This technology requires a fixed boiler room to generate heat and heat the heat medium, and transmit the heat medium to each Users also need a dedicated transmission line, which occupies a large area and has high maintenance and operating costs; and the energy loss of existing transmission pipelines is also worth utilizing. If the heat lost and generated can be utilized, it can be invested in transmission pipelines more fully use of energy

Embodiment Construction
[0023] An embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0024] In this embodiment, a waste heat utilization device used for power transmission pipelines utilizes the heat emitted by the internal conductors of power transmission pipelines in a heat exchange manner to firstly treat the 25# transformer oil in the high temperature resistant insulating liquid 25# transformer oil chamber. Heating, transfer heat to the high temperature resistant insulating liquid, meanwhile the high temperature resistant insulating liquid heats the metal heat exchange layer, the metal heat exchange layer heats the water inside, and the hot water is used by users in residential areas, such as Figure 1-2 As shown, a waste heat utilization device for power transmission pipelines includes:
[0025] Hollow copper tube 1, metal heat exchange layer 3, shell 4, oil conservator 5, buffer water tank 6 and thermometer 7;
[0026] The met...

The invention provides a waste heat utilization device used for a power transmission pipeline, and belongs to the technical field of power-transmission heat supply. The waste heat utilization device used for the power transmission pipeline comprises a hollow copper pipe, a metal heat-exchange layer, a shell, an oil conservator, a buffering water tank and a thermometer, wherein the metal heat-exchange layer is arranged outside the hollow copper pipe, and high-temperature-resistant insulating liquid is injected into a cavity between the metal heat-exchange layer and the hollow copper pipe; the metal heat-exchange layer is of a hollow structure, and water is injected into the metal heat-exchange layer; the shell is arranged outside the metal heat-exchange layer, high-temperature-resistant insulating liquid is injected into a cavity between the shell and the metal heat-exchange layer, and the two ends of the hollow copper pipe are connected with a hollow copper pipe in the power transmission pipeline; the oil conservator communicates with a high-temperature-resistant insulating liquid chamber, and both the buffering water tank and the thermometer communicate with the metal heat-exchange layer; and a water inlet valve and a water outlet valve which are connected with a user heat supply side are arranged on the two sides of the metal heat-exchange layer. According to the waste heat utilization device used for the power transmission pipeline, a heat-supply heating place does not need to be specially established, and the temperature of heating media can meet the requirement by means of the loss of the power transmission pipeline; the heat utilization device can be selectively mounted on the power transmission pipeline nearby according to the position of a user, the heating medium transmission distance is shortened, temperature fall of the heating media in the transmission process is decreased, and the length of the pipeline is decreased.
