[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] like Figure 1 、 Figure 2As shown, the utility model discloses a heating system, which includes: a heating component, which is connected to the user end and is used to provide heat to the user end; a heat exchange component 8, which has a heat exchange part, a first heat exchange pipe and a second heat exchange pipe, the first heat exchange pipe and the second heat exchange pipe can exchange heat through the heat exchange part, the first end of the first heat exchange pipe is connected to a heat exchange medium supply source, and the second heat exchange pipe forms a loop with the heating component; a heat storage component 4, which is connected to the second end of the first heat exchange pipe, and the heat storage component 4 is connected to the heating component through the first heat supply pipe; a first valve 9, which is arranged on the first heat exchange pipe and is located between the second end of the first heat exchange pipe and the heat exchange part; a second valve, which is arranged on the second heat exchange pipe; and a third valve 10, which is arranged on the first heat supply pipe.

[0032] When the heating component is in the heating trough period, the first valve 9 and the second valve are opened, and the heat of the heating component is transferred to the heat exchange medium in the first heat exchange pipe through the second heat exchange pipe and the heat exchange part, and the heat exchange medium storing excess heat of the heating component is stored in the heat storage component 4 through the first heat exchange pipe; when the heating component is in the heating peak period, the third valve 10 is opened, and the excess heat generated by the heating component during the heating trough period is directly transferred to the heating component through the heat exchange medium, and then heat is provided to the user end; this not only enables the heating component to utilize the excess heat generated during the heating trough period during the heating peak period, thereby reducing the heating cost of the heating system, but also avoids the energy loss generated in the process of transferring the heat in the heat storage component 4 to the heating component through the heat exchanger, thereby improving the utilization efficiency of the heat stored in the heat storage component 4, and further reducing the heating cost of the heating system.

[0033] At the same time, due to the presence of the heat storage component 4, the heating system can operate within a relatively high thermal efficiency range, thereby improving the thermal efficiency of the heating system. In addition to the good economic performance mentioned above, the heating system also has good environmental benefits.

[0034] The first valve 9 is disposed between the second end of the first heat exchange pipe and the heat exchange portion, so that the heat exchange medium in the heat exchange portion can be transported to the heat storage component 4 after fully absorbing the heat of the heat supply component. This can be achieved by the operator periodically opening the first valve 9. Alternatively, a temperature sensor can be disposed in the area of ​​the first heat exchange pipe located in the heat exchange portion, and the temperature sensor can be used to monitor the temperature of the heat exchange medium located in the heat exchange portion of the first heat exchange pipe, thereby achieving more accurate opening of the first valve 9. The first valve 9, the second valve, and the third valve 10 can be opened manually by the operator, or, in order to improve the degree of automation of the heating system, a controller can be provided to control the automatic opening of the first valve 9, the second valve, and the third valve 10. When the controller is required to control the opening of the valve, the first valve 9, the second valve, and the third valve 10 are all connected to the controller signal. To facilitate the control of the controller, the first valve 9, the second valve, and the third valve 10 can be specifically solenoid valves.

[0035] The heat exchange medium can flow through the first heat exchange pipe, the second heat exchange pipe, and the first heat supply pipe by means of corresponding pumps, or by tilting the first heat exchange pipe, the second heat exchange pipe, and the first heat supply pipe so as to utilize the heat exchange medium's own weight to achieve gravity flow. However, it should be noted that when tilting the first heat exchange pipe, the second heat exchange pipe, and the first heat supply pipe, it is necessary not to interfere with the line of sight of other structural functions and not to affect the normal operation of the heating system. In addition, the heat exchange medium delivered to the heating component through the first heat supply pipe of the present invention can be directly used by the heating component to generate heat.

[0036] The heating component can specifically be a boiler or other equipment capable of generating or supplying heat. When the heating component is a boiler, a deaerator 7 is also provided on the first heating pipe to remove any oxygen that may be present in the first heating pipe, thereby minimizing oxidation of the first heating pipe. The specific structure of the heat exchange component 8 can refer to existing heat exchanger configurations and only requires that the heat exchange between the first and second heat exchange pipes be sufficient. The specific structure of the heat exchange component 8 is not further described here. The heat exchange medium also has a certain heat storage capacity and can specifically be a medium with both heat exchange and heat storage capabilities, such as water or air.

[0037] Furthermore, in the present invention, the first heat exchange pipe, the second heat exchange pipe and the third heat exchange pipe are further provided with a heat exchange medium processing component, and / or the heat exchange medium supply source is connected to the heat supply component. Figure 1As shown, the heat exchange medium supply source can specifically be a desalted water tank 2. At this time, the heat exchange medium is water, and after being processed by the desalted water tank 2, the probability of pipeline corrosion damage is reduced. The heat exchange medium processing component may include a mixed bed 1 (the mixed bed 1 can be understood as an ion exchange column) provided on the first heat exchange pipeline and located upstream of the heat exchange medium supply source. A valve 3 is provided between the mixed bed 1 and the heat exchange medium supply source for controlling the time for the heat exchange medium to be processed by the mixed bed 1. The mixed bed 1 can reduce the hardness, alkalinity and anions and cations in the water, making it softened water or deionized water. A cold slag pump 6 (the cold slag pump 6 shell is specifically a centrifugal pump) is provided between the heat exchange medium supply source and the heating component, and a desalted water pump 5 (the desalted water pump 5 can be understood as a special pump for transporting brine) is provided on the first heating pipeline. The heat exchange cutoff processing component is not limited to the above-mentioned mixed bed 1, cold slag pump 6 and desalted water pump 5, and can also be set to activated carbon and other structures that can process the heat exchange medium to prevent pipeline corrosion damage and blockage.

[0038] In addition, the heat exchange medium supply source is connected to the heating component through a pipeline. This allows for when the sum of the heat exchange medium stored in the heat storage component 4 and the heat generated by the heating component itself is insufficient to meet the heating demand during peak periods of heating demand. The valve on the pipeline between the heat exchange medium supply source and the heating component can be opened to directly supply the heat exchange medium to the heating component, thereby reducing the heat exchange medium delivery time and improving the heating efficiency of the heating component.

[0039] The thermal storage assembly 4 in this utility model can take various forms. For example, the thermal storage assembly 4 may include a thermal storage tank; and / or, the thermal storage assembly 4 may include a heat exchanger, which is buried underground. The phrase "and / or" means that within the same sentence, the text preceding and / or and the text following and / or can exist simultaneously or separately. For example, "A and / or B" includes both A and B, as well as only A or B.

[0040] The heating system also includes a first insulation layer disposed outside the heat exchange component 8, and a second insulation layer disposed outside the first heat supply pipe. The first channel within the first insulation layer is connected to the second channel within the second insulation layer, and both the first channel and the second channel are filled with a heat-conducting medium. By filling the first insulation layer with the heat-conducting medium, heat dissipated from the heat exchange component 8 to the outside is absorbed. The heat is then transferred to the second insulation layer by the heat-conducting medium flowing between the first and second insulation layers. The heat carried by the second insulation layer and the heat-conducting medium prevents heat from leaking out of the heat exchange medium within the first heat supply pipe, thereby reducing energy loss during the heat exchange medium's transfer from the heat storage component 4 to the heat supply component, further satisfying the heat supply needs of the heat supply component and reducing the heating cost of the heating system. Similarly, a third insulation layer can be disposed outside the heat storage component 4, and the third channel within the third insulation layer is connected to the second channel, thereby utilizing the heat dissipated by the heat storage component 4 itself and minimizing energy loss during the heat exchange medium's transfer to the heat supply process. The flow of the heat-conducting medium between the first insulation layer and the second insulation layer, and the flow between the third insulation layer and the second insulation layer can be respectively transported by corresponding conveying equipment such as pumps.

[0041] The heat exchange component also includes a third heat exchange pipe, which is connected to the solar collector to form a closed loop, and the third heat exchange pipe can exchange heat with the first heat exchange pipe through the heat exchange part. By setting the third heat exchange pipe, the excess heat generated by the solar collector is also transferred to the heat exchange medium, and then stored in the heat storage component, thereby increasing the heat storage capacity of the heat storage component and making the heat storage component have a stronger response capability during the peak heating period. The solar collector can specifically be a structure that generates heat using solar energy. The heat can exist in the form of hot water, steam, etc., or be stored in other types of heat exchange media; hot water, steam or other heat exchange media that store heat generated by solar energy can be transported in the third heat exchange pipeline through a pump conveying device. It should be noted that at this time, the heating component in the present invention does not include a structure that can generate heat using solar energy.

[0042] A temperature sensor is provided at the second end of the first heat exchange pipe; the heat storage assembly includes several heat storage tanks, each of which is connected to the second end of the first heat exchange pipe, and a heat storage valve is provided at the inlet of each heat storage tank. Each heat storage tank is connected to the heat supply assembly through its own heat supply pipe, and each heat supply pipe is provided with its own heat supply valve. The heat storage tanks are used to store heat exchange media in the same temperature range, and the heat exchange media in each temperature range is stored by at least one heat storage tank; the temperature sensor and the heat storage valve are both connected to the controller signal; wherein the heat storage valve is in a normally closed state; the temperature sensor is used to detect the temperature of the heat exchange medium located at the second end of the first heat exchange pipe and output a temperature signal to the controller; the controller is used to receive the temperature signal, determine the temperature range to which the temperature signal belongs, and open the corresponding heat storage valve according to the temperature range to which the temperature signal belongs.

[0043] A sufficient number of heat storage tanks and heat storage valves are provided based on factors such as the number of temperature zones, the heat storage capacity of the heat exchange medium, and the amount of heat to be stored. The second end of the first heat exchange pipe is connected to the inlet of each heat storage tank. Before the first heat exchange pipe transports the heat exchange medium into the heat storage tank, the heat storage valves are all closed. When the controller receives the temperature signal output by the temperature sensor and determines the temperature zone to which the temperature signal belongs, it opens the heat storage tank used to store heat in that temperature zone, that is, opens the heat storage valve located at the inlet of the heat storage tank, thereby achieving hierarchical storage of heat in the heating component during low-peak heating periods, so that the heating valves on the corresponding heating pipes can be opened during peak heating periods to achieve hierarchical utilization of heat, achieving efficient heat utilization and further reducing heating costs.

[0044] The present invention discloses a plurality of technical solutions, but does not provide any contrary technical suggestions.

[0045] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
