[0011] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0012] In the description of the embodiments of the present utility model, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate an orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, it is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0013] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0014] In the description of the embodiments of the present invention, "multiple" means at least 2.

[0015] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0016] Example:

[0017] like Figure 1 As shown, the boiler heat collection energy-saving auxiliary water tank includes a heat collection tank 10 and an auxiliary water tank 20;

[0018] A heat collecting tube 11 is provided inside the heat collecting box 10, and a chimney inlet 12 and a chimney outlet 13 are provided at the upper and lower ends of the heat collecting tube 11, respectively;

[0019] The auxiliary water tank 20 is located at one side of the heat collecting tank 10 and is connected to the heat collecting tank 10 through a pipe 30. The auxiliary water tank 20 is provided with a float valve 21 and a water inlet 22;

[0020] In actual application, the flue gas generated when the boiler is running enters the heat collecting tube 11 through the chimney inlet 12, and is discharged from the chimney outlet 13 after heat exchange with the hot water. The design of the heat collecting tube 11 enables the heat energy in the flue gas to be effectively recovered and transferred to the hot water. As the temperature of the hot water increases, part of the hot water flows into the auxiliary water tank 20 through the pipeline 30 for storage. When the water level in the auxiliary water tank 20 reaches the set value, the float valve 21 automatically closes the water inlet 22 to prevent water overflow.

[0021] In addition, an interface 14 connected to the main tank is provided on the upper part of one side of the thermal collector box 1, so that the thermal collector box 10 can be connected to the main tank of the boiler to realize the circulation of hot water. A drain outlet 15 is provided on the lower part of the other side of the thermal collector box 10 to facilitate the discharge of sewage or cleaning and maintenance.

[0022] To sum up, the boiler heat collection energy-saving auxiliary water tank of the present invention, through the combination of the heat collection tank and the auxiliary water tank, collects the waste heat of the boiler and the steam generator chimney, so that the water temperature of the auxiliary water tank is increased by 50 degrees, thereby realizing efficient recovery and energy-saving utilization of thermal energy, improving the energy utilization efficiency of the boiler system, and saving a lot of fuel at the same time, and has broad application prospects.

[0023] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
