Description

TECHNICAL FIELD

[0001] The present application relates to the field of high-temperature heat storage and energy-saving technology, and particularly relates to an energy-saving and efficient high-temperature device. BACKGROUND

[0002] The current paraffin heat storage technology mainly adopts the whole heat storage mode, needs more coil pipes, has low heat storage temperature, and has high investment. The water heat storage system has a large volume and occupies a large space in the building. There is a lack of heat storage devices with small volume in the current market. SUMMARY

[0003] In view of the above defects, the present application provides an energy-saving and efficient high-temperature device. During valley electricity, a control system controls a wind-cooled heat pump host to generate heat, and the heat is released to paraffin through a condenser. When the temperature of the paraffin reaches 65 DEG C, the wind-cooled heat pump host is turned off. If the heat storage capacity has met the subsequent heating demand at this time, the paraffin is not heated any more. If the heat storage capacity is insufficient at this time, the paraffin is further heated by an electric heating pipe until the subsequent heating demand is met or the paraffin reaches 120 DEG C. During peak electricity, the control system controls a pipe-external rotary blade to rotate, and the paraffin flows from the hot water supply pipe to the hot water return pipe through the blade. At the same time, the low-temperature water from the hot water return pipe is heated after flowing through the condensing pipe and flows out from the hot water supply pipe. Thus, the purpose of relieving peak electricity by using heat storage is achieved.

[0004] To achieve the purpose, the present application adopts the following technical scheme: An energy-saving and efficient high-temperature device comprises a hot water supply pipe, a hot water return pipe, a condensing pipe, a pipe-external rotary blade, paraffin, a heat storage tank, a condenser, a wind-cooled heat pump host, an electric heating pipe and a control system.

[0005] The control system can realize heat storage control and heat release control. During heat storage, the control system controls the wind-cooled heat pump host to supply high-temperature refrigerant to the condenser, so that the paraffin melts in the melting point range of 55 DEG C to 65 DEG C. After the temperature of the paraffin reaches 65 DEG C, the wind-cooled heat pump is stopped, and the paraffin is further heated to 120 DEG C by the electric heating pipe. During heat release, the paraffin is condensed after heat exchange with the liquid in the condensing pipe, and is scraped off by the rotating pipe-external rotary blade and falls back to the heat storage tank.

[0006] The condensing pipe and the pipe-external rotary blade are both horizontally installed, so that the heat of the liquid paraffin at the top can be fully utilized.

[0007] The melting point of the paraffin is 55 DEG C to 65 DEG C.

[0008] The condensing pipe, the pipe-external rotary blade, the condenser and the electric heating pipe are all installed in the heat storage tank.

[0009] The outer-rotating scraping blade of the pipe is a spiral blade, which stirs the top liquid paraffin while scraping the solid paraffin, so that the paraffin flows from the hot water supply pipe direction to the hot water return pipe direction.

[0010] The technical solution of the present application can include the following beneficial effects: 1. During off-peak electricity, the control system controls the air-cooled heat pump host to heat and release heat to the paraffin through the condenser, and after the paraffin temperature reaches 65℃, the air-cooled heat pump host is turned off. If the heat storage capacity at this time has met the subsequent heating demand, no further heating is required. If the heat storage capacity at this time is insufficient, the control system controls the electric heating pipe to further heat the paraffin until the subsequent heating demand is met, or the paraffin reaches 120℃. During peak electricity, the control system controls the outer-rotating scraping blade of the pipe to rotate, and the blade makes the paraffin flow from the hot water supply pipe direction to the hot water return pipe direction, while the low-temperature water from the hot water return pipe is heated after flowing through the condensing pipe and flows out from the hot water supply pipe. Thus, the purpose of using heat storage to relieve peak electricity is achieved. BRIEF DESCRIPTION OF DRAWINGS

[0016] The following describes an energy-saving and efficient high-temperature device according to an embodiment of the present application. Figure 1

[0017] An energy-saving and efficient high-temperature device, comprising a hot water supply pipe 1, a hot water return pipe 2, a condensing pipe 3, an outer-rotating scraping blade 4, paraffin 5, a heat storage tank 6, a condenser 7, an air-cooled heat pump host 8, an electric heating pipe 9 and a control system 10.

[0018] The control system 10 can realize heat storage control and heat release control. During heat storage, the control system 8 controls the air-cooled heat pump host 8 to supply high-temperature refrigerant to the condenser 7, so that the paraffin 5 melts at a melting point range of 55-65℃. After the temperature of the paraffin 5 reaches 65℃, the air-cooled heat pump stops; the paraffin 5 is heated by the electric heating pipe 9 to further increase the temperature to 120℃. During heat release, the paraffin 5 exchanges heat with the liquid inside the condensing pipe 3 and condenses, and the outer-rotating scraping blade 4 is scraped off and returned to the heat storage tank 6.

[0019] The condensing pipe 3 and the outer-rotating scraping blade 4 are horizontally installed, which facilitates full utilization of the heat of the top liquid paraffin 5.

[0020] The melting point of the paraffin 5 is 55-65℃.

[0021] The condensing pipe 3, the outer-rotating scraping blade 4, the condenser 7 and the electric heating pipe 9 are all installed in the heat storage tank 6.

[0022] The outer-rotating scraping blade 4 is a spiral blade, which stirs the top liquid paraffin 5 while scraping off the solid paraffin 5, so that the paraffin 5 flows from the direction of the hot water supply pipe 1 to the direction of the hot water return pipe 2.

[0023] ​During valley electricity, the control system 10 controls the air-cooled heat pump host 8 to heat, and releases heat to the paraffin 5 through the condenser 7. When the temperature of the paraffin 5 reaches 65℃, the air-cooled heat pump host 8 is turned off. If the heat storage amount at this time has met the subsequent heating demand, no further heating is needed. If the heat storage amount at this time is insufficient, the electric heating tube 9 is further controlled to heat the paraffin 5 until the subsequent heating demand is met, or until the paraffin 5 reaches 120℃. Thus, the purpose of heat storage using valley electricity is achieved. During peak electricity, the control system 10 controls the rotation of the outer-rotating blade 4, and the paraffin 5 flows from the hot water supply pipe 1 to the hot water return pipe 2 through the blade. At the same time, the low-temperature water from the hot water return pipe 2 is heated after flowing through the condensing pipe 3, and flows out from the hot water supply pipe 1. Thus, the purpose of relieving peak electricity demand by using heat storage is achieved.

[0024] The technical principles of the present application are described above in combination with specific embodiments. These descriptions are only for the purpose of explaining the principles of the present application, and cannot be interpreted in any way as a limitation on the scope of protection of the present application. Based on the explanations herein, those skilled in the art can think of other specific embodiments of the present application without creative labor, and these embodiments will fall within the scope of protection of the present application.
