Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a standing double-panel heat exchanger. Background Technology

[0002] A heat exchanger is a device whose main function is to transfer some of the heat from a hot fluid to a cold fluid, thereby achieving heat exchange between two fluids at different temperatures. Heat exchangers play an important role in many industrial production processes such as chemical, petroleum, power, and food industries, and can be used as heaters, coolers, condensers, evaporators, and reboilers.

[0003] Traditional heat exchangers use a single tube sheet design, which results in low structural strength, small heat exchange area, and a risk of cross-contamination between different materials. They are only suitable for working conditions with low hygiene requirements, and the material heat exchange efficiency is low, leading to heat energy waste. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a standing double-section heat exchanger, which overcomes the shortcomings of the prior art and effectively solves the problems of easy cross-contamination between different materials and low heat exchange efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A standing double-section heat exchanger includes a shell, a tube box is fixedly connected to one end of the outer wall of the shell via a flange, and an outer cover is fixedly connected to the other end of the outer wall of the shell via a flange. A hot fluid inlet and a cold fluid outlet are welded to both sides of the tube box, and a cold material inlet is welded to the bottom of one side of the outer wall of the shell, and a hot material outlet is welded to one side of the outer wall of the outer cover.

[0007] The housing contains a tube bundle, and a baffle plate is fixedly connected to the outer wall of the tube bundle.

[0008] Preferably, a front fixed tube sheet and a rear floating tube sheet are fixedly connected to both ends of the housing, and the tube bundle is installed between the front fixed tube sheet and the rear floating tube sheet.

[0009] Preferably, a spacer tube is welded to the outer wall of the baffle plate.

[0010] Preferably, a floating head is fixedly connected to one side of the outer wall of the rear floating tube plate via a flange, and the floating head is located inside the outer cover.

[0011] Preferably, a gasket is provided between the housing and the tube box, and gaskets are provided in the inner wall grooves of the front fixed tube plate and the rear floating tube plate.

[0012] Preferably, anti-impact plates are fixedly connected to both ends of the outer wall of the tube bundle.

[0013] Preferably, a partition plate is welded to the inner wall of the tube box, and an inlet chamber and an outlet chamber are respectively provided on both sides of the partition plate inside the tube box.

[0014] Preferably, a base is welded at the center of the bottom outer wall of the pipe box.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The standing double-layer heat exchanger designed in this paper has a tube box and an outer cover at each end of the shell. Compared with the traditional single tube sheet heat exchanger, it has high structural strength and a larger heat exchange area, eliminates the possibility of contact between the two materials, and improves the quality of the materials after heat exchange.

[0017] 2. The standing double-section heat exchanger designed in this paper has multiple vertically distributed baffles inside the shell. As the cold material enters the shell through the cold material inlet and exits through the hot material outlet, the flow velocity of the fluid is slowed down, the heat transfer time is increased, and the heat exchange efficiency is improved.

[0018] 3. The standing double-panel heat exchanger in this design adopts a standing double-panel structure, which makes it easier to ventilate and keep the inside of the shell clean. The double tube sheet structure avoids the risk of cross-contamination that is common in conventional heat exchangers and can be applied to more hygienic working conditions.

[0026] In this embodiment, a tube box 2 and an outer cover 3 are added to each end of the shell 1. Compared with the traditional tube sheet heat exchanger, it has high structural strength and a larger heat exchange area, eliminates the possibility of contact between the two materials, and improves the quality of the materials after heat exchange.

[0027] Example 2, refer to Figure 1 A standing double-section heat exchanger, wherein hot fluid inlet 4 and cold fluid outlet 5 are welded to both sides of the tube box 2, and cold material inlet 6 is welded to the bottom of one side of the outer wall of the shell 1, and hot material outlet 7 is welded to one side of the outer wall of the outer cover 3.

[0028] In this embodiment, multiple vertically distributed baffles 12 are provided inside the shell 1. As the cold material enters the shell 1 through the cold material inlet 6 and exits through the hot material outlet 7, the flow rate of the fluid is slowed down, the heat transfer time is increased, and the heat exchange efficiency is improved.

[0029] Example 3, refer to Figure 3 A standing double-section heat exchanger, wherein a tube bundle 10 is provided inside the shell 1, and a baffle plate 12 is fixedly connected to the outer wall of the tube bundle 10.

The double tube sheet structure avoids the risk of cross-contamination that is common in conventional heat exchangers and can be applied to more hygienic working conditions.

[0031] Reference Figure 3 The two ends of the housing 1 are respectively fixedly connected to a front fixed tube sheet 8 and a rear floating tube sheet 9, and the tube bundle 10 is installed between the front fixed tube sheet 8 and the rear floating tube sheet 9.

[0037] Reference Figure 1 A base 20 is welded to the center of the bottom outer wall of the pipe box 2.

[0038] Working principle: During the process of cold material entering the shell 1 through cold material inlet 6 and exiting through hot material outlet 7, the cold material will continuously come into contact with the baffle plate 12 and undergo multiple up and down flow. The hot fluid enters the tube box 2 through the hot fluid inlet 4, then flows into the floating head 13 along one side of the tube bundle 10, and then returns to the other side of the tube bundle 10 and exits through the cold fluid outlet 5. The cold material and the hot fluid will exchange heat to complete the heat exchange operation.
