Description

Technical Field

[0001] This application relates to the field of multi-energy complementary heating technology, and in particular to a solar-biomass multi-energy complementary heating system. Background Technology

[0002] With the continuous development of the economy and the improvement of people's living standards, more and more families are using heaters for heating in winter. Most heating equipment on the market uses solar energy as the main heating source. As a renewable and clean energy source, solar energy is widely loved by people. However, the thermal energy of solar energy is limited by weather conditions. Therefore, there is an urgent need for multi-energy complementary heating and energy storage systems to solve people's problems.

[0003] Chinese patent CN114636185A, entitled "A Multi-Energy Complementary Central Heating Control System and Method Thereof," utilizes a photosensitive sensor in conjunction with a servo motor to align the rotation of the water heater with the direction of sunlight. Simultaneously, steam flows into the gap between the inner and outer casings, forming an insulation layer to prevent heat loss from the inner casing. The steam then flows into the circulation pipe to heat the water inside the water heater. In this way, the combined heat of the steam and the sunlight accelerates the heating of the water in the water heater, thus utilizing the heat and avoiding resource waste.

[0004] Chinese patent CN211781379U, entitled "A Multi-Energy Complementary Clean Heating System," utilizes a solar collector as the primary energy source and an electric boiler operating during off-peak hours as a secondary energy source to store heat in a phase change thermal storage device. During periods of continuous cloudy or rainy weather, the electric boiler primarily stores heat. The heat stored in the phase change thermal storage device is used to supply heat to the outside environment. When the phase change thermal storage device is in its storage period, a water source heat pump system provides the external heating. This system enables uninterrupted heating for users around the clock while simultaneously reducing heating costs.

[0005] In existing technologies such as the aforementioned patents, when using clean energy for complementary heating, solar energy and biomass energy are usually combined to heat circulating water to achieve complementary heating. However, the heating efficiency of the circulating water is low, and after prolonged heating, a large amount of impurities and dirt will be generated in the circulating water. The circulating water cannot be cleaned and replaced regularly, which affects the heating transfer effect of the circulating water. Based on this, there is still room for improvement on the existing multi-energy complementary heating system. Summary of the Invention

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Please see Figures 1-8 This invention provides a solar-biomass multi-energy complementary heating system, comprising a photovoltaic substrate 1 and a heating geothermal pipe 2, and further comprising: multiple support frames 3; a circulating heating furnace 4, which is fixedly installed on the upper part of the support frames 3, with a water storage chamber in the middle of the circulating heating furnace 4; the photovoltaic substrate 1 is connected to the circulating heating furnace 4; the circulating heating furnace 4 heats the inside of the water storage chamber in a multi-energy complementary manner; when the solar energy conversion efficiency of the photovoltaic substrate 1 is high, the circulating heating furnace 4 uses solar energy for heating; when the solar energy conversion efficiency is low, the circulating heating furnace 4 can be heated by electric heating or by biomass fuel; a connecting component 5, which is installed on one side of the circulating heating furnace 4, and is used to circulate the circulating hot water inside the circulating heating furnace 4 to the heating geothermal pipe 2; and a flue pipe 6, which is installed on the upper part of the circulating heating furnace 4, and is used to discharge the flue gas generated during the combustion of biomass energy.

[0030] Meanwhile, an energy storage power supply is also installed above the circulating heating furnace 4. When the solar energy conversion efficiency is high, the solar energy heats the circulating water inside the circulating heating furnace 4 to the required temperature. The electrical energy converted by the solar energy is stored inside the energy storage power supply so that it can be used when the solar energy conversion efficiency is low. This allows the solar energy, biomass and electric heating energy to complement each other, reducing energy waste and saving resources.

[0031] Specifically, solar energy is the primary energy source. When solar energy is abundant, the photovoltaic substrate 1 converts solar energy into electrical energy. The electrical energy first powers the circulating heating furnace 4 for electric heating. When the temperature of the circulating water inside the circulating heating furnace 4 reaches the required level, the photovoltaic substrate 1 stores the electrical energy converted from solar energy in the energy storage power supply for subsequent use inside the circulating heating furnace 4. When there is no sunlight for a long time, the circulating heating furnace 4 is connected to an external power source and can continue to perform electric heating. When burning biomass fuel, the heat generated during the combustion of biomass energy heats the circulating water inside the circulating heating furnace 4. At this time, the electrical energy and the electrical energy stored in the energy storage power supply stop being used, thereby reducing energy waste.

[0032] See Figures 2-3 As shown, in this preferred embodiment, the circulating heating furnace 4 includes a heating furnace body 41, a spiral frame 42, a combustion frame 43, and a heating frame 44. The heating furnace body 41 has a cylindrical hollow structure. The combustion frame 43 is installed at the lower end of the heating furnace body 41 and is connected to the interior of the heating furnace body 41. A ring-shaped water storage cavity is provided in the middle of the heating furnace body 41. The spiral frame 42 is installed in the middle of the water storage cavity. A spiral groove is provided between the spiral frame 42 and the interior of the heating furnace body 41. A ring-shaped mounting groove is provided on the outer side of the heating furnace body 41. The heating frame 44 is installed on the ring-shaped mounting groove. An opening is provided on the right side of the heating frame 44, and a connecting component 5 is installed in the opening.

[0033] In the above technical solution, the spiral frame 42 can divide the interior of the heating furnace body 41 into spiral grooves, so that the circulating water inside the heating furnace body 41 can flow along the spiral grooves. When the heating frame 44 heats the heating furnace body 41, the heat generated by the heating frame 44 heats the circulating water through the outer wall of the heating furnace body 41. When the combustion frame 43 burns biomass fuel, the heat generated by the combustion frame 43 heats the circulating water through the inner wall of the heating furnace body 41.

[0034] See Figures 2-3 As shown, as a preferred technical solution in this embodiment, the spiral frame 42 is made of heat-conducting metal and is used to transfer the heat generated by the inner and outer walls of the heating furnace body 41 to the circulating water in the water storage chamber.

[0035] In the above technical solution, when solar energy or biomass energy heats the heating furnace body 41, the spiral frame 42 not only guides the circulating water but also transfers heat, so that the heat can be accurately transferred to the circulating water.

[0036] See Figure 4As shown, as a preferred technical solution of this embodiment, the combustion rack 43 includes a mounting rack 431 disposed at the bottom of the heating furnace body 41. The mounting rack 431 has an L-shaped cross-section, and a sliding rack 432 is slidably disposed at the upper end of the mounting rack 431. The sliding rack 432 is used to support the biomass fuel.

[0037] In the above technical solution, when the solar energy conversion efficiency is low, the heating furnace body 41 can be heated by biomass combustion. When biomass combustion is carried out, the biomass fuel is placed on the upper end of the sliding frame 432, and the heat generated by the combustion of biomass fuel heats the inner wall of the heating furnace body 41, thereby realizing the function of biomass energy for heating.

[0038] See Figures 4-5 As shown, in this preferred embodiment, the heating rack 44 has an arc-shaped groove evenly arranged on its inner wall, and a heating tube 441 is installed in the arc-shaped groove. The heating tube 441 has an arc-shaped structure, and an electrical terminal 443 is provided at the end of the heating tube 441. A heat-conducting frame 442 is wrapped around the outside of the heating tube 441. The heat-conducting frame 442 is in close contact with the outer wall of the heating furnace body 41, and the heat-conducting frame 442 is made of heat-conducting material.

[0039] In the above technical solution, the heating tube 441 can heat the furnace body 41, and the heat conduction frame 442 can conduct heat, so that the heat generated by the heating tube 441 can be accurately transferred to the interior of the furnace body 41, ensuring accurate heating of the circulating water inside the furnace body 41.

[0040] See Figures 6-8 As shown, in this preferred embodiment, the connection component 5 includes a connecting frame 51, an electrical connection frame 52, a filter component 53, an inlet pipe 54, and an outlet pipe 55. The connecting frame 51 has a rectangular structure and is installed at the opening by screws. The electrical connection frame 52 is symmetrically installed on the inner side of the connecting frame 51. The electrical connection frame 52 cooperates with the electrical connection terminal 443 on the heating tube 441. The filter component 53 is installed in the middle of the connecting frame 51, and the inner side of the filter component 53 is located inside the spiral groove. The inlet pipe 54 is installed at the lower front end of the connecting frame 51, and the outlet pipe 55 is installed at the upper front end of the connecting frame 51. The inner sides of the inlet pipe 54 and the outlet pipe 55 are connected to the inside of the spiral groove.

[0041] In the above technical solution, after the connecting frame 51 is installed, the electrical connection frame 52 can accurately cooperate with the electrical connection terminal 443, so that the electrical connection terminal 443 can heat the heating tube 441. The liquid inlet pipe 54 and the liquid outlet pipe 55 are connected to the circulating water pump. When the circulating water pump drives the hot water circulation, the filter component 53 can accurately filter and clean the circulating water to prevent impurities from accumulating and depositing in the circulating water.

[0042] See Figures 7-8As shown, in a preferred embodiment, the filter assembly 53 includes a connector 531, a sealing plate 532, and a filter frame 533. The connector 51 has a through groove in the middle, the connector 531 is located inside the through groove, the sealing plate 532 is installed between the connector 531 and the through groove, and sealing gaskets are evenly distributed on the sealing plate 532. The filter frame 533 is evenly installed inside the connector 531, and the filter frame 533 is located inside the spiral groove. Sealing frames that cooperate with the filter frame 533 are evenly distributed inside the spiral groove.

[0043] In the above technical solution, the filter frame 533 can be evenly arranged inside the spiral groove on the filter frame 533. The filter frame 533 is sealed and matched with the sealing frame inside the spiral groove, so that the circulating water can only pass through the inside of the filter frame 533. When the circulating water flows inside the spiral groove, the filter frame 533 can filter and remove the circulating water, prevent impurities from settling in the circulating water, and facilitate the circulation and heating of the circulating water.

[0044] See Figure 8 As shown, as a preferred technical solution of this embodiment, the filter frame 533 includes a filter frame 5331, a wire mesh frame 5332, and a filter screen 5333. The filter frame 5331 has a parallelogram structure, the middle part of the filter frame 5331 is hollow, the wire mesh frame 5332 is installed inside the filter frame 5331, and the filter screen 5333 is installed on the outer surface of the filter frame 5331.

[0045] In the above technical solution, the wire mesh frame 5332 can support the filter screen 5333. Under the action of high-pressure circulating water, it prevents the filter screen 5333 from being deformed by pressure, so that the filter screen 5333 can accurately filter the circulating water and prevent the accumulation of circulating water from affecting the heating effect of the heating pipe 2.

[0046] Continue reading Figure 8 As shown, as a preferred technical solution in this embodiment, the filter holes of the internal filter screen 5333 of the heating furnace body 41 gradually decrease from bottom to top, and a collection net bag 5334 is uniformly arranged on the outer surface of the filter screen 5333.

[0047] In the above technical solution, the filter holes of the filter screen 5333 inside the heating furnace body 41 gradually decrease from bottom to top, so that the filter screen 5333 can filter the circulating water layer by layer, and impurities on the outside of the circulating water can stay on the outside of the filter screen 5333. The collection bag 5334 can collect the impurities and avoid secondary pollution of the circulating water by the impurities.

[0048] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
