Description

Technical Field

[0001] This utility model relates to the field of boiler cluster heating technology, and more specifically, to a distributed heating architecture and heating system based on boiler clusters. Background Technology

[0002] Currently, centralized heating systems, as an important component of modern social infrastructure, provide basic guarantees for residents' lives, industrial production, and public services, and significantly improve the quality of life during the cold season.

[0003] Boiler clusters, as the core heat source of a heating system, typically consist of several boilers. In traditional heating models, each boiler corresponds to a different heating terminal to provide heat. Currently, for terminals with high heating demands, in addition to the heat supplied by the corresponding boiler, these boilers often need to borrow heat from other boilers to meet their needs. This is especially problematic when the number of terminals connected to the boiler cluster is large, easily leading to a complex overall piping structure and cumbersome control valve settings, making subsequent inspection and maintenance difficult.

[0044] like Figures 1 to 2 As shown, this utility model embodiment provides a distributed heating architecture based on a boiler cluster and a heating system including the distributed heating architecture. The distributed heating architecture includes an outer boiler structure 1, a convergence and diversion structure 2, a heat source storage structure 3, and a supplementary heating boiler structure 4. The outer boiler structure 1 effectively forms a boiler cluster, serving as the heat source foundation for the overall architecture. Simultaneously, the convergence and diversion structure 2 can transfer heat from the outer boiler structure 1 and further directly distribute it to each heating terminal on demand, significantly reducing the complexity of the pipeline architecture. Furthermore, the heat source storage structure 3 can effectively serve as a temporary storage for the convergence and diversion structure 2 when there is an excess of internal heat source or as a supplementary heat storage for when there is a lack of internal heat source. The supplementary heating boiler structure 4 can further supplement heat directly to the convergence and diversion structure 2 or supplement heat after transmission heating based on the heat source storage structure 3, effectively ensuring the simplicity and functional stability of the overall pipeline architecture and improving subsequent maintenance efficiency. Specific settings are as follows:

[0045] Please refer to Figure 1 and Figure 2 The peripheral boiler structure 1 is provided in at least two sets, and the at least two sets of peripheral boiler structures 1 are arranged in an array to form a boiler cluster architecture as the heat source basis.

[0046] The agglomeration and diversion structure 2 includes an annular agglomeration chamber 21, agglomeration heat inlet pipe body 22, a heat distribution pipe body 23, and a flow control valve 24. The annular agglomeration chamber 21 is configured as an annular pipe body, and at least two agglomeration heat inlet pipe bodies 22 are connected to it. Each of the at least two agglomeration heat inlet pipe bodies 22 is connected to at least two sets of heat source outlet ends of the peripheral boiler structure 1, allowing the heat source output from the peripheral boiler structure 1 to be diverted to the annular agglomeration chamber 21 via pipes. Several heat distribution pipe bodies 23 are provided, and these pipes are distributed and assembled in a decentralized manner within the annular agglomeration chamber 21. Each of the heat distribution pipes 23 is equipped with a flow control valve 24, enabling direct, on-demand heat distribution to each heating terminal without the need for separate pipework for heat source borrowing, thus ensuring simplicity.

[0047] As a preferred embodiment, several of the heat distribution pipes 23 are arranged to cross each other with at least two of the heat collection pipes 22 to improve the flow of heat sources inside the annular heat collection chamber 21.

[0048] More preferably, the annular agglomeration chamber 21 is also equipped with at least two sets of agglomeration temperature sensors 25 in a distributed manner to monitor the local temperature of the flowing heat source inside the annular agglomeration chamber 21 in real time.

[0049] Please continue to refer to this. Figure 1 and Figure 2 The heat source storage structure 3 includes a storage container body 31, a storage heat inlet pipe body 32, and a storage pumping pipe body 34. The storage container body 31 is located inside the annular accumulation chamber 21, and its bottom side is connected to the annular accumulation chamber 21 via the storage heat inlet pipe body 32 in a closed-loop manner. This allows the storage container body 31 to effectively serve as a temporary storage chamber for the accumulation and diversion structure 2 when there is an excess of internal heat source. One end of the storage pumping pipe body 34 is connected to the storage container body 31, and the other end is connected to the annular accumulation chamber 21. This allows the storage container body 31 to effectively serve as a supplementary heat storage chamber for the accumulation and diversion structure 2 when there is a lack of internal heat source.

[0050] As another preferred embodiment, the storage container body 31 is also equipped with a storage temperature sensor 33, which is used to monitor the internal heat source temperature of the storage container body 31 in real time, thereby avoiding the impact on the internal heat source temperature of the annular accumulation chamber 21 due to insufficient heat source temperature requiring supplemental heating.

[0051] More preferably, the bottom side of the storage container body 31 is also connected to a heating transmission pipe 35, and the supplementary heating boiler structure 4 includes a supplementary heating boiler body 41 and a supplementary heating pump pipe 42; wherein, the storage container body 31 is closed-loop connected to one of the input ends of the supplementary heating boiler body 41 through the heating transmission pipe 35, and the heat source output end of the supplementary heating boiler body 41 is closed-loop connected to the annular agglomeration chamber 21 through the supplementary heating pump pipe 42, so that the supplementary heating process can be completed by secondary heating of the low-temperature heat source inside the storage container body 31 with the help of the supplementary heating boiler body 41, effectively ensuring the overall heating function stability of the annular agglomeration chamber 21.

[0052] More preferably, another input end of the supplementary heating boiler body 41 is also connected to a supplementary heating water inlet pipe 43, which serves as a separate water inlet, enabling the supplementary heating boiler body 41 to function as an independent heat source, thereby significantly improving the overall heating function stability.

[0053] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
