[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 described embodiments 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 creative work 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 embodiments.

[0031] like Figure 1 , Figure 2As shown, the present invention discloses a heating system, which includes: a heating component, which is connected to a user end and is used to provide heat to the user end; a heat exchange component 8, which has a heat exchange portion, 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 portion, 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 portion; 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 the 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 in the heating trough period is directly transferred to the heating component through the heat exchange medium, and then heating is provided to the user end; this not only enables the heating component to utilize the excess heat generated in 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; and while the heating system has the above-mentioned good economy, it also has good environmental benefits.

[0034] The first valve 9 is arranged between the second end of the first heat exchange pipe and the heat exchange part, so that the heat exchange medium in the heat exchange part can be transported to the heat storage component 4 after fully absorbing the heat of the heating component. This can be achieved by the operator regularly opening the first valve 9, or a temperature sensor can be arranged in the area of ​​the first heat exchange pipe located in the heat exchange part, and the temperature sensor is used to monitor the temperature of the heat exchange medium located in the heat exchange part in the first heat exchange pipe, thereby realizing a 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 automation degree of the heating system, a controller can be set to control the automatic opening of the first valve 9, the second valve and the third valve 10. When the controller needs 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. In order 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 flow of the heat exchange medium in the first heat exchange pipe, the second heat exchange pipe and the first heat supply pipe can be transported by a corresponding pump, or the first heat exchange pipe, the second heat exchange pipe and the first heat supply pipe can be tilted to achieve gravity flow by using the weight of the heat exchange medium. However, it should be noted that when the first heat exchange pipe, the second heat exchange pipe and the first heat supply pipe are tilted, the sight of other structural functions should not be interfered with, and the normal operation of the heating system should not be affected. In addition, the heat exchange medium transported to the heating component through the first heating pipe of the present invention can be directly used by the heating component to generate heat.

[0036] The heating component can be a boiler or other equipment that can generate or supply heat. When the heating component is a boiler, a deaerator 7 is also provided on the first heating pipe. The deaerator removes oxygen that may exist in the first heating pipe to avoid oxidation of the first heating pipe as much as possible. The specific structure of the heat exchange component 8 can refer to the existing heat exchanger settings, and it can meet the heat exchange between the first heat exchange pipe and the second heat exchange pipe. The specific structure of the heat exchange component 8 is not repeated here. The heat exchange medium also has a certain heat storage capacity. The heat exchange medium can be water, air, and other media that have both heat exchange and heat storage capabilities.

[0037] Furthermore, in the present invention, the first heat exchange pipe, the second heat exchange pipe and the third heat exchange pipe are also 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 treated by the desalted water tank 2, the probability of pipeline corrosion damage is reduced. The heat exchange medium treatment component can include a mixed bed 1 (the mixed bed 1 can be understood as an ion exchange column) arranged on the first heat exchange pipeline and located upstream of the heat exchange medium supply source. A valve 3 for controlling the treatment time of the heat exchange medium by the mixed bed 1 is provided between the mixed bed 1 and the heat exchange medium supply source. The mixed bed 1 can reduce the hardness, alkalinity and anions and cations in the water to make it softened water or deionized water. A cold slag pump 6 (the cold slag pump 6 shell is specifically a centrifugal pump) is arranged 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 conveying brine) is arranged on the first heating pipeline. The heat exchange cutoff treatment 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 treat 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 the valve on the pipeline between the heat exchange medium supply source and the heating component to be opened during the peak period of heating demand, 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. The heat exchange medium can be directly supplied to the heating component to reduce the heat exchange medium transportation time and improve the heating efficiency of the heating component.

[0039] The heat storage component 4 in the present invention has various forms. For example, the heat storage component 4 includes a heat storage tank; and / or, the heat storage component 4 includes a heat exchanger, and the heat exchanger is buried underground. And / or means that in the same sentence, the text content located before and / or and the text content located after and / or can exist at the same time or separately. For example, A and / or B. This includes the existence of A and B at the same time, and only A or B exists.

[0040] The heating system also includes a first insulation layer arranged outside the heat exchange component 8, and a second insulation layer arranged outside the first heating pipe. The first channel in the first insulation layer is connected to the second channel in the second insulation layer, and the first channel and the second channel are filled with heat-conducting medium. By filling the first insulation layer with heat-conducting medium, the heat emitted to the outside by the heat exchange component 8 is absorbed, and the heat is filled in the second insulation layer by the flow of the heat-conducting medium between the first insulation layer and the second insulation layer. The heat of the heat exchange medium in the first heating pipe is prevented from leaking out by the heat carried by the second insulation layer and the heat-conducting medium, thereby reducing the energy loss of the heat exchange medium in the process of being transported from the heat storage component 4 to the heating component, further meeting the heating demand of the heating component, and reducing the heating cost of the heating system. Similarly, a third insulation layer can be arranged outside the heat storage component 4, and the third channel in the third insulation layer is connected to the second channel, so as to utilize the heat emitted by the heat storage component 4 itself and avoid the energy loss of the heat exchange medium in the heating process as much as possible. 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 transported by corresponding conveying equipment such as pumps.

[0041] The heat exchange component also includes a third heat exchange pipeline, which is connected to the solar collector to form a closed loop, and the third heat exchange pipeline can exchange heat with the first heat exchange pipeline through the heat exchange part. By setting the third heat exchange pipeline, 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, so that the heat storage component has a stronger response capability during the peak heating period. The solar collector can specifically be a structure that generates heat using solar energy, and 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 using solar energy can be transported in the third heat exchange pipeline through the pump conveying equipment. 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 a plurality of heat storage tanks, each of which is connected to the second end of the first heat exchange pipe, 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 pipeline is provided with its own heat supply valve, the heat storage tanks are used to store heat exchange medium in the same temperature range, and the heat exchange medium 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 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 according to the number of divided temperature intervals, 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 in a closed state. When the controller receives the temperature signal output by the temperature sensor and determines the temperature interval to which the temperature signal belongs, the heat storage tank for storing the temperature interval is opened, that is, the heat storage valve at the inlet of the heat storage tank is opened, thereby realizing the hierarchical storage of heat of the heating component during the low-peak heating period, so that the heating valve on the corresponding heating pipe can be opened during the peak heating period to realize the hierarchical utilization of heat, thereby achieving the effective utilization of heat and further reducing the heating cost.

[0044] The present invention discloses multiple technical solutions, but there is no situation in which contrary technical inspiration is given.

[0045] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
