Description

Technical Field

[0001] This utility model relates to the technical field of dip-impregnation production lines, specifically to a thermal energy storage device for dip-impregnation lines. Background Art

[0002] In the traditional copper clad laminate industry, the boards need to be dried after being impregnated with adhesive. The flue gas generated during the drying process is directly emitted after combustion. This process does not involve heat recovery and is directly emitted. The heat energy required by other equipment can only be provided by additional boilers, resulting in high production costs and significant waste of heat energy.

[0003] To improve the utilization rate of thermal energy, the current method is to exchange heat between flue gas and circulating water in the heat exchanger, and then store the hot water after heat exchange in an insulated water tank. However, the existing heat exchangers use a straight tube design, which results in fast water flow and short tube distance, leading to low heat exchange efficiency and requiring multiple heat exchange processes to complete thermal energy storage. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a heat storage device for dipped wires, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A heat storage device for impregnated wire includes a combustion boiler, the flue gas outlet of which is connected to a water circulation heat exchange box. A heat exchange tube is vertically arranged inside the water circulation heat exchange box. A heat storage tank is located outside the water circulation heat exchange box, and the heat storage tank has an inlet and an outlet. The inlet is connected to the outlet end of the heat exchange tube via an inlet pipe, and the outlet is connected to the inlet end of the heat exchange tube via an outlet pipe. The heat exchange tube includes a vertical tube, and a spiral tube is arranged outside the vertical tube. The upper end of the vertical tube is connected to the upper end of the spiral tube outside the vertical tube via a bend, and the lower end of the spiral tube is connected to the lower end of an adjacent vertical tube via a bend. Several vertical tubes and the spiral tube outside the vertical tube constitute the overall structure of the heat exchange tube inside the water circulation heat exchange box.

[0007] Furthermore, the vertical tube is located at the center of the spiral tube, and the spiral tubes outside the vertical tube are arranged in an alternating manner with the adjacent bolt tubes.

[0008] Furthermore, a circulating water pump is installed on the outlet pipe.

[0009] Furthermore, the exterior of the thermal energy storage tank is provided with an insulation layer.

[0010] Compared with the prior art, the heat exchange tube of this utility model adopts a spiral tube structure, which extends the tube length and improves the heat exchange efficiency. At the same time, the staggered arrangement of the spiral tubes reduces the size of the heat exchanger and reduces the area occupied by the equipment. Attached Figure Description

[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0015] like Figure 1 and Figure 2 As shown, a heat storage device for impregnated wire includes a combustion boiler 1. The flue gas outlet of the combustion boiler 1 is connected to a water circulation heat exchange box 2. A heat exchange tube 3 is vertically arranged inside the water circulation heat exchange box 2. A heat storage water tank 4 is arranged outside the water circulation heat exchange box 2. The heat storage water tank 4 is provided with an inlet and an outlet. The inlet is connected to the outlet end of the heat exchange tube 3 through an inlet pipe 5. The outlet is connected to the inlet end of the heat exchange tube 3 through an outlet pipe 6. A circulating water pump 7 is installed on the outlet pipe 6.

[0016] In this embodiment, the heat exchange tube 3 includes a vertical tube 311, and a spiral tube 312 is disposed outside the vertical tube 311. The upper end of the vertical tube 311 is connected to the upper end of the spiral tube 312 disposed outside the vertical tube 311 through a bend 313. The lower end of the spiral tube 312 is connected to the lower end of the adjacent vertical tube 311 through a bend 314. Several vertical tubes 311 and the spiral tubes 312 disposed outside the vertical tubes 311 constitute the overall structure of the heat exchange tube in the water circulation heat exchange box 2. The spiral tubes 312 disposed outside the vertical tubes 311 are used to form the overall structure of the heat exchange tube in the water circulation heat exchange box 2. The spiral tube 312 slows down the water flow rate, increases the tube length, and improves heat exchange efficiency. During heat exchange, when the water temperature in the water circulation heat exchange box 2 exceeds 70°C, the circulating water pump 7 starts to run, transporting the water in the thermal energy storage tank 4 to the water circulation heat exchange box 2 through the outlet pipe 6 for heat exchange, and then returning to the thermal energy storage tank 4 for storage through the inlet pipe 5. When the water temperature in the water circulation heat exchange box 2 is lower than 70°C, the circulating water pump 7 stops running, and at the same time, the outlet and inlet of the thermal energy storage tank 4 are closed through valves, allowing the thermal energy to be stored for a long time for future needs.

[0017] The thermal energy storage tank 4 is provided with an insulation layer 8 on the outside, which enables the hot water in the thermal energy storage tank 4 to be stored for a long time.

[0018] In this embodiment, the vertical tube 311 is located at the center of the spiral tube 312. The spiral tube 312 outside the vertical tube 311 and the adjacent bolt tube 312 are arranged in an alternating manner. The alternating arrangement can reduce the size of the heat exchange box and reduce the floor space.

[0019] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
