Description

Technical Field

[0001] This utility model belongs to the field of heat exchange devices, specifically relating to a tiered water circulation device. Background Technology

[0002] The existing tiered water circulation device involves spirally winding a single pipe around the outer wall of a hot fluid pipe. Hot water or hot smoke flows through the hot fluid pipe, while cold water flows through the spiral pipe. As the cold water circulates in the spiral pipe, it absorbs the heat emitted by the hot fluid pipe, thus playing a role in heat exchange.

[0003] This technology has many drawbacks. For example, the inlet and outlet of a single spiral pipe are unique, making it impossible to classify the absorbed heat and then output it in stages. Another example is that the heat is high near the inlet of the hot fluid pipe and low far from the inlet, resulting in low heat absorption efficiency of the spiral pipe. Utility Model Content

[0004] The present invention provides a tiered water circulation device that can effectively solve the problems in the background art.

[0005] This utility model provides a tiered water circulation device, comprising:

[0006] Fluid conduits used for the flow of hot fluids;

[0007] It includes several arc-shaped pipes connected end to end to form a circulation pipe that can fit the outer arc surface of the fluid pipe, and the circulation pipe is provided with no less than two sets;

[0008] And a three-way valve that connects the water inlets of several sets of circulating pipes in series.

[0009] As a further optimization of this utility model, the circulation pipeline is provided in two sets, and each circulation pipeline is formed as a semi-circular arc surface corresponding to the outer arc surface of the fluid pipeline.

[0010] As a further optimization of this utility model, the circulation pipeline is provided in three sets, and each set of circulation pipelines is formed as a one-third arc surface corresponding to the outer arc surface of the fluid pipeline.

[0011] As a further optimization of this utility model, the three-way valve adopts a solenoid valve.

[0012] As a further optimization of this utility model, the arc-shaped pipes in the circulation pipeline are arranged in a linear array.

[0013] As a further optimization of this utility model, the arc-shaped pipes in the circulation pipeline are arranged at unequal intervals.

[0014] As a further optimization of this utility model, the arc-shaped pipe in the circulation pipe has a smaller distance between the hot fluid inlet end of the fluid pipe and the hot fluid inlet end of the fluid pipe.

[0015] As a further optimization of this utility model, the circulation pipeline is provided in two sets, and the two sets of circulation pipelines are formed as a whole into an arc shape corresponding to the outer arc surface of the fluid pipeline. The arc-shaped pipelines of the two sets of circulation pipelines are staggered and inserted.

[0016] This utility model provides a tiered water circulation device, in which several sets of circulation pipes can be freely disassembled and assembled without interfering with each other; the water circulation path can be adjusted by a three-way valve to select the heat level; and it makes full use of the characteristic that the heat of the fluid gradually decreases from the inlet end to the outlet end of the hot fluid in the fluid pipe, so as to absorb heat more fully.

[0020] Among them, fluid pipe 1, circulation pipe 2, arc-shaped pipe 2a, U-shaped pipe 2b, and three-way valve 3. Detailed Implementation

[0021] Example 1

[0022] like Figure 1-3 As shown, this embodiment includes a fluid pipeline 1, a circulation pipeline 2, and a three-way valve 3.

[0023] Fluid pipe 1 is a large circular pipe used to circulate hot fluids, including hot water, heated smoke, or gas.

[0024] The circulation pipe 2 includes an arc-shaped pipe 2a and a U-shaped pipe 2b.

[0025] The arc shape of the arc-shaped pipe 2a corresponds to that of the fluid pipe 1, and the arc-shaped pipe 2a can fit precisely with the outer arc surface of the fluid pipe 1. There are several arc-shaped pipes 2a arranged in a linear array.

[0026] The two ends of the U-shaped pipe 2b are respectively connected to one end of two adjacent arc-shaped pipes 2a, and several U-shaped pipes 2b connect several arc-shaped pipes 2a in series to form a connected pipe.

[0027] In this embodiment, the arc-shaped pipe 2a is a semi-circular arc shape corresponding to the outer arc surface of the fluid pipe 1. Therefore, the entire set of circulation pipes 2, including the arc-shaped pipe 2a and the U-shaped pipe 2b, forms a semi-circular arc shape corresponding to the outer arc surface of the fluid pipe 1.

[0028] This embodiment is provided with two sets of circulation pipes 2, which can just hold the fluid pipe 1.

[0029] Two of the valve ports of the three-way valve 3 are respectively connected to one of the water pipe ports of the two sets of circulation pipes 2. Under the action of the three-way valve 3, the water entering from one set of circulation pipes 2 can be discharged directly from the other valve port of the three-way valve 3 after heat exchange, or the water entering from one set of circulation pipes 2 can enter the next set of circulation pipes 2 for secondary heat exchange after heat exchange under the action of the three-way valve 3.

[0030] This embodiment has at least the following advantages:

[0031] 1) Two sets of circulation pipes 2 can be installed in one or two sets without interference. Alternatively, after installing two sets, one set can be used or both sets can be used for water circulation heat exchange.

[0032] 2) The three-way valve 3 can be used to adjust the water circulation path, choosing either a longer path for more thorough heat exchange or a shorter path for faster heat exchange.

[0033] 3) As the heat of fluid pipe 1 gradually decreases from the inlet end to the outlet end of hot fluid, when cold water passes through a set of circulation pipes 2, it flows from the end with high heat to the end with low heat in fluid pipe 1. Then, when it passes through the second set of circulation pipes 2, it flows back from the end with low heat to the end with high heat in fluid pipe 1, thus making the cold water absorb heat more fully.

[0034] Example 2

[0035] This embodiment is basically the same as Embodiment 1, except that it has three sets of circulation pipes. The curvature of the arc-shaped pipe in each set is only one-third of the curvature of the outer arc surface of the fluid pipe. Therefore, the circulation pipe as a whole forms a one-third arc surface corresponding to the outer arc surface of the fluid pipe. The three sets of circulation pipes can also hold the entire fluid pipe.

[0036] The three sets of circulation pipes are connected in series through two three-way valves.

[0037] This embodiment further improves the heat absorption effect by circulating the fluid back and forth between the high-heat end and the low-heat end of the fluid pipe through a circulation pipe.

[0038] Example 3

[0039] This embodiment is basically the same as Embodiment 1, except that in this embodiment, the several arc-shaped pipes of the circulation pipe are arranged at unequal intervals, that is, the spacing between adjacent arc-shaped pipes is not equal.

[0040] Specifically, in this embodiment, the distance between the hot fluid inlet end near the fluid pipe and the hot fluid inlet end far from the fluid pipe is smaller. This setting allows the water circulation path to be longer at the end of the fluid pipe with high heat, thus improving the heat absorption effect at this stage. At the same time, the water circulation path is shorter at the end of the fluid pipe far from the hot fluid, which shortens the heat absorption time of the water at this stage and reduces heat loss.

[0041] Example 4

[0042] This embodiment is basically the same as Embodiment 1, except that the two sets of circulation pipes in this embodiment are formed as a superior arc surface corresponding to the outer arc surface of the fluid pipe, and the arc-shaped pipes of the two sets of circulation pipes are staggered and inserted.

[0043] This embodiment improves heat absorption by increasing the contact path between the circulation pipe and the fluid pipe.

[0044] Preferably, in this example, the three-way valve is a solenoid valve, which can achieve automatic control.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
