Description

Technical Field

[0001] This utility model belongs to the technical field of heating network heaters, and specifically relates to an energy-saving heating network heater. Background Technology

[0002] Heat exchanger heaters are key equipment in urban district heating systems, primarily used to transfer heat from flowing hot water or steam to the heat exchanger network for end-user use. They typically employ a shell-and-tube heat exchanger structure, characterized by high efficiency and compactness, ensuring effective energy utilization and meeting heating demands in different seasons.

[0003] In existing heat network heaters, the heating medium is typically in the shell side, while the heated fluid is in the tube side. Furthermore, the flow path in the shell side is usually cylindrical, resulting in a short flow distance for the heating medium within the shell side. Consequently, the heating medium does not fully exchange heat with the heated fluid before flowing out of the shell side, leading to a certain degree of heat waste. Therefore, a new type of energy-saving heat network heater is needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses an energy-saving heating network heater.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An energy-saving heat network heater includes a tank body with a hollow end cap installed at the opening. A plurality of fixed concentric cylinders are coaxially fixedly connected to the inner cavity of the tank body. A plurality of movable concentric cylinders are coaxially fixedly connected to one side of the hollow end cap. The fixed and movable concentric cylinders are interleaved to divide the inner cavity of the tank body into a reciprocating tortuous flow channel extending from the axis to the annular outer wall. A plurality of heat exchange tubes extending in the same direction as the reciprocating tortuous flow channel are installed within the reciprocating tortuous flow channel. One end of each heat exchange tube passes through the hollow end cap and is connected to an integrated ring. The other end of each heat exchange tube is connected to an integrated plug. A separator is fixedly embedded in the tank body, and the integrated plug is connected to the inner cavity of the separator. The outer cavity of the separator is connected to the axis end of the reciprocating tortuous flow channel, and the annular outer wall end of the reciprocating tortuous flow channel is connected to the inner cavity of the hollow end cap.

[0007] As a preferred embodiment of this utility model, the opening of the integrated plug is connected to the separator, and the separator has several through holes that communicate with the integrated plug.

[0008] As a preferred embodiment of this utility model, the separator has several through holes for connecting its outer cavity with the reciprocating tortuous flow channel inside the tank.

[0009] As a preferred technical solution of this utility model, the hollow end cap is provided with a number of through holes for connecting its inner cavity with the reciprocating tortuous flow channel inside the tank.

[0010] As a preferred embodiment of this utility model, the heat exchange tube is provided with several turbulence rings, and each turbulence ring is provided with several annularly distributed spiral blades.

[0011] In a preferred embodiment of this invention, the turbulence ring is fixedly connected to the heat exchange tube.

[0012] As a preferred embodiment of this invention, the turbulence ring is rotatably connected to the heat exchange tube.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this application, the heating medium flows through a reciprocating tortuous flow channel within the tank, and several heat exchange tubes extending in the same direction as the reciprocating tortuous flow channel are installed within the channel. This extends the flow distance of the heating medium in the shell side, facilitating heat exchange between the tube side and the shell side. Simultaneously, the opposing flow of the heating medium and cold water within the tank results in high heat exchange efficiency. Furthermore, the initial inflow of the heating medium into the tank's axis minimizes heat dissipation to the outside. This application improves heat exchange efficiency, reduces heat loss, and is energy-efficient.

[0015] 2. After removing several sets of bolts and nuts between the tank body and the hollow end cover, the fixed concentric cylinder, the hollow end cover, the movable concentric cylinder, the heat exchange tube, the integrated ring and the turbulence ring can be coaxially extracted from the tank body together, reducing the difficulty of maintenance.

[0024] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0025] Please see Figure 1-6 An energy-saving heat network heater includes a tank 1 with a hollow end cap 3 installed at the opening of the tank 1. Several coaxial fixed concentric cylinders 2 are coaxially fixedly connected to the inner cavity of the tank 1. The tank 1 and the hollow end cap 3 are fixedly connected by several sets of bolts and nuts. Several coaxial movable concentric cylinders 4 are coaxially fixedly connected to one side of the hollow end cap 3, and the fixed concentric cylinders 2 and movable concentric cylinders 4 are interleaved to divide the inner cavity of the tank 1 into a reciprocating tortuous flow channel extending from the axis to the annular outer wall. Several heat exchange tubes 5 extending in the same direction as the reciprocating tortuous flow channel are installed in the reciprocating tortuous flow channel, and the heat exchange tubes 5 are evenly distributed in a ring. One end of each heat exchange tube 5 passes through the hollow end cap 3 and is connected to an integrated ring 6; the other end of each heat exchange tube 5 is connected to an integrated plug 8. Both the hollow end cap 3 and the integrated ring 6 extend to flange joints for connection with external pipelines. A separator 7 is fixedly embedded in the tank body 1, and an integrated plug 8 communicates with the inner cavity of the separator 7. The outer cavity of the separator 7 communicates with the axial end of the reciprocating tortuous flow channel, and the annular outer wall end of the reciprocating tortuous flow channel communicates with the inner cavity of the hollow end cover 3. Flange joints for connecting to external pipelines extend from the inner and outer cavities of the separator 7, respectively.

[0026] The opening of the integrated plug 8 is inserted into the splitter 7, and the splitter 7 has several through holes communicating with the integrated plug 8. Specifically, the splitter 7 has several through holes communicating with the integrated plug 8 evenly distributed in a ring.

[0027] The separator 7 has several through holes for connecting its outer cavity with the reciprocating tortuous flow channel inside the tank 1. Specifically, the separator 7 has several through holes that are evenly distributed in a ring shape to connect with the reciprocating tortuous flow channel inside the tank 1.

[0028] The hollow end cap 3 has several through holes for connecting its inner cavity with the reciprocating tortuous flow channel inside the tank 1. Specifically, the hollow end cap 3 has several through holes that are evenly distributed in a ring shape to connect with the reciprocating tortuous flow channel inside the tank 1.

[0029] The heat exchange tube 5 is fitted with several turbulence rings 9, and each turbulence ring 9 is equipped with several evenly distributed annular spiral blades. The turbulence rings 9 can be fixedly connected to the heat exchange tube 5, or they can be rotatably connected. When the heating medium flows, it is disturbed by the blades of the turbulence rings 9, which ensures that the heating medium has full contact with the heat exchange tube 5 during flow.

[0030] Working principle:

[0031] During operation, the outer cavity of the separator 7 is vented with heating medium from the outside, and the integrated ring 6 is vented with cold water (the fluid being heated) from the outside. Then, the heating medium flows into the reciprocating tortuous flow channel inside the tank 1. The heating medium flows from the axis of the tank 1 to the annular outer wall in the reciprocating tortuous flow channel. Then, the heating medium flows into the hollow end cap 3 and then flows out. At the same time as the heating medium flows, the cold water flows from the integrated ring 6 into several heat exchange tubes 5. When the cold water flows in the heat exchange tubes 5, it exchanges heat with the heating medium flowing in the shell side and is heated. After the cold water is heated into hot water, it flows into the inner cavity of the separator 7 through the integrated plug 8 and finally flows out. The heat exchange efficiency is high because the heating medium and cold water flow in opposite directions in the tank 1, and the initial flow of the heating medium into the axis of the tank 1 minimizes the heat loss to the outside.

[0032] After removing several sets of bolts and nuts between the tank body 1 and the hollow end cover 3, the fixed concentric cylinder 2, the hollow end cover 3, the movable concentric cylinder 4, the heat exchange tube 5, the integrated ring 6 and the turbulence ring 9 can be coaxially pulled out from the tank body 1 together for easy maintenance.

[0033] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
