Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent temperature control, and particularly relates to an intelligent temperature control device for a heat exchange station. Background Art

[0002] With the continuous advancement of industrialization and urbanization, centralized heating systems have become an important part of modern urban infrastructure, especially an important part of municipal work in northern cities in my country. With the continuous expansion of the scale of urban centralized heating and the improvement of people's quality of life, cities, enterprises, and factories have increasingly higher requirements for heat exchange technology. As a key link in the centralized heating system, the operating efficiency and stability of the heat exchange station directly affect the heating quality and energy consumption.

[0003] Heat exchange stations, also known as heating stations, are where heat is concentrated and exchanged. Based on the type of heat supplied, they are categorized as direct-supply stations and indirect-supply stations. The former, where power plants directly supply heat to users, results in high temperatures, difficult control, and wasteful heat energy. This is a legacy of the original use of waste heat from power plants for welfare heating. With the development of the commodity economy and the commercialization of heat, heating companies have begun to improve the quality of their heat supply.

[0004] The secondary feed water temperature control of the heat exchange station has always been an important factor in the energy consumption of the heat exchange station. Because the feed water temperature is usually lower than the secondary return water temperature, the secondary network return water temperature will usually be lowered after being injected into the secondary network. After the secondary return water enters the heat exchanger, it needs to be heated up and turned into secondary supply water to be supplied to heat users again. If the secondary return water temperature is lowered, more energy will be consumed to heat it up after entering the heat exchanger, which will directly affect the energy saving efficiency of the heat exchange station.

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Please also refer to Figures 1 to 5 The intelligent temperature control device for a heat exchange station of the present invention is described below. The intelligent temperature control device for a heat exchange station includes a heat supply unit 10, a water supply unit 20, and a temperature rise unit 30. The heat supply unit 10 includes a heat exchanger 101, and a water supply pipeline 102 and a return pipeline 103 connecting the heat exchanger 101 and the heat user. The water supply unit 20 includes a water tank 201, and a water supply pipeline 202 connecting the water tank 201 and the return pipeline 103, with a valve installed on the water supply pipeline 202. The temperature rise unit 30 includes a power storage unit that converts solar energy into electrical energy, a heating unit that converts electrical energy into thermal energy, and a heat transfer unit that transfers heat to the water supply pipeline 202.

[0028] Compared with the prior art, the self-cleaning and dust removal equipment provided in this embodiment has the following advantages:

[0029] Solar energy is converted into electrical energy, which is then converted into thermal energy. This thermal energy is then used to heat the water in the feed water line 202, thereby aligning the temperature of the water in the feed water line 202 with the water in the return water line 103. When the water in the feed water line 202 and the water in the return water line 103 merge, the water in the feed water line 202 does not lower the temperature of the water in the return water line 103. Consequently, the water in the return water line 103 consumes less energy when it enters the heat exchanger 101, improving the energy efficiency of the heat exchange station.

[0030] In some embodiments, see Figure 2 and Figure 3 The intelligent temperature control device of the heat exchange station also includes a positioning unit 40; the temperature rising unit 30 includes a solar cell panel 301 forming a power storage unit; the positioning unit 40 has a mounting portion for fixing the solar cell panel 301, a rotation portion for rotating the solar cell panel 301, and a control portion for controlling the rotation angle of the rotation portion.

[0031] It should be noted that the solar panel 301 is always aligned with the sun.

[0032] The solar panel 301 converts solar energy into electrical energy, and uses the converted electrical energy to power the heating unit, thereby the heating unit 30 heats the water in the water supply pipeline 202 to increase the temperature.

[0033] The control unit adjusts the rotation angle of the indexing unit so that the solar panel 301 rotates along the sun's trajectory, thereby always aligning the solar panel 301 with the sun, thereby achieving the best solar energy absorption and conversion effect of the solar panel 301.

[0034] In some embodiments, see Figure 3 The positioning unit 40 includes a mounting frame 401 forming a mounting portion, and a plurality of limiting plates 4011 are fixed to the circumferential side of the mounting frame 401. The solar cell panel 301 is arranged in an area surrounded by the plurality of limiting plates 4011. The limiting plates 4011 are internally threadedly connected to a limiting screw 4012, and the limiting screw 4012 abuts against the solar cell panel 301.

[0035] After placing the solar panel 301 in the area surrounded by the plurality of limiting plates 4011, screw the limiting screw 4012 so that the limiting screw 4012 is pressed against the side of the solar panel 301. Figure 3 The structure in FIG. 4 is a method for positioning the limiting plate 4011. There are no restrictions on the position of the limiting plate 4011. Multiple limiting plates 4011 can be arranged in a square or triangle. The position of the limiting plates 4011 can be determined based on actual needs. The limiting plates 4011 can be directly fixed to the mounting frame 401, such as by welding. Alternatively, the limiting plates 4011 and the mounting frame 401 can be detachably fixed, such as with bolts. This allows the mounting frame 401 to be used to mount solar panels 301 of various sizes and shapes, thereby increasing the applicability of the mounting frame 401.

[0036] In some embodiments, see Figure 3The adjustment unit 40 includes a turntable 402 and a motor 403 forming an indexing portion. The turntable 402 rotates around its own central axis. The mounting portion is fixed to the turntable 402 , and the output shaft of the motor 403 is fixed to the turntable 402 .

[0037] In some embodiments, see Figure 4 The positioning unit 40 includes a computer forming a control part, and the computer controls the rotation angle of the output shaft of the motor 403 according to the daily movement trajectory of the sun.

[0038] The computer presets the sun's trajectory according to the daily weather conditions, generates a rotation instruction based on the preset sun's trajectory, and then transmits the rotation instruction to the motor 403. After receiving the rotation instruction, the motor 403 drives the turntable 402 to rotate through its own output shaft, and the turntable 402 drives the solar panel 301 to rotate through the mounting portion.

[0039] In some embodiments, see Figure 3 and Figure 5 The heating unit 30 includes a heating box 302 containing water, a heat pipe 303 forming a transfer part, and an electric heating rod 304 forming a heating part. The heat pipe 303 has an inlet end connected to the heating box 302 and an outlet end connected to the heating box 302. A power pump is installed on the heat pipe 303, and the electric heating rod 304 is electrically connected to the solar cell panel 301.

[0040] In some embodiments, see Figure 5 The heat conducting pipe 303 is spirally wound around the outer periphery of the water supply pipeline 202 .

[0041] The solar panel 301 supplies electricity to the electric heating rod 304, and the electric heating rod 304 generates heat. The heat heats the water in the heating box 302 and the heated water circulates in the heat pipe 303. The heated water transfers heat to the water supply pipeline 202 during the circulation process, thereby heating the water in the water supply pipeline 202.

[0042] In some embodiments, the outer periphery of the heat pipe 303 is wrapped with a heat-insulating material. Specifically, the heat-insulating material can be a glass fiber wool board or a polyurethane foam material. The heat-insulating material can reduce the heat exchange between the heat pipe 303 and the external environment, thereby playing a role in keeping the heat pipe 303 and the water supply pipeline 202 warm.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
