Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger components, and particularly relates to a novel shell-and-tube heat exchanger component. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in many industrial productions such as chemical industry, petroleum, power, food and others. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators, reboilers, etc., and are widely used.

[0003] Generally, the water inlet and outlet of a shell-and-tube heat exchanger are separated and only one pipeline is used for heat exchange operation, resulting in low efficiency. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a novel shell-and-tube heat exchanger component, which has a simple structure. During the heat exchange process, the liquid to be heat-exchanged and the coolant are completely separated without leakage. At the same time, multiple heat exchange pipelines increase the heat exchange area and further enhance the heat exchange effect. The water inlet and outlet are arranged on the same side, and the liquid to be heat-exchanged has to contact the coolant twice, improving the heat exchange efficiency.

[0005] To solve the above technical problem, the utility model provides a novel shell-and-tube heat exchanger component, which is characterized in that it includes a heat exchange mechanism, and an inlet / outlet water component and a sealing component are respectively arranged at both ends of the heat exchange mechanism; the heat exchange mechanism includes a housing and heat exchange pipelines. Support plates are arranged at intervals inside the housing, and the heat exchange pipelines penetrate through the support plates and are connected to the inlet / outlet water components and the sealing components on both sides. A coolant inlet is arranged on the housing near the inlet / outlet water component, and a coolant outlet is arranged on the housing near the sealing component.

[0006] Further, symmetric hanging ear components are arranged at the top of the housing.

[0007] Further, the heat exchange mechanism includes two flange components arranged at the ends, and the flange components are adapted to the inlet / outlet water components and the sealing components.

[0008] Further, the inlet / outlet water component includes a first protective shell and a first connecting flange. The first connecting flange is adapted to the flange component. An inlet and an outlet are respectively arranged at the upper and lower ends of the first protective shell, and a first baffle is arranged inside the first protective shell.

[0009] Further, the sealing component includes a second protective shell and a second connecting flange. The second connecting flange is adapted to the flange component, and a second baffle with the same position as the first baffle is arranged inside the second protective shell.

[0010] Furthermore, a support base is provided at the bottom of the heat exchange mechanism.

[0011] Advantages of the present utility model: When the device is in use, the water inlet is opened. The heat exchange pipes are divided into upper and lower parts by the first baffle. The liquid to be heat-exchanged enters the inner part of the upper heat exchange pipes from the water inlet. At this time, the coolant inlet is opened simultaneously, and the coolant enters the interior of the housing and contacts the heat exchange pipes. Since there are multiple heat exchange pipes, the contact area is wide and the heat exchange efficiency is high. At this time, the liquid to be heat-exchanged enters the sealing assembly after primary heat exchange. The second baffle in the sealing assembly is in the same position as the first baffle but does not completely block the upper and lower heat exchange pipes. Therefore, the liquid to be heat-exchanged will enter the lower heat exchange pipes from the upper heat exchange pipes, and thus can conduct secondary contact heat exchange with the coolant, further improving the heat exchange efficiency. Then, it flows out from the water outlet at the bottom of the water inlet and outlet assembly to complete the heat exchange operation, and the coolant flows out from the coolant outlet for recycling.

[0022] Referring to Figures 1 to 3 As shown, an embodiment of a novel shell-and-tube heat exchanger assembly of the present utility model includes a heat exchange mechanism. Both ends of the heat exchange mechanism are respectively provided with a water inlet and outlet assembly 3 and a sealing assembly 4; the heat exchange mechanism includes a housing 1 and heat exchange pipes 2. Support plates 5 are arranged at intervals inside the housing 1. The heat exchange pipes 2 penetrate through the support plates and are connected to the water inlet and outlet assembly 3 and the sealing assembly 4 on both sides. A coolant inlet 6 is provided at a position on the housing 1 close to the water inlet and outlet assembly 3, and a coolant outlet 7 is provided at a position on the housing 1 close to the sealing assembly 4;

[0023] The water inlet and outlet assembly 3 includes a first protective shell 31 and a first connecting flange 32. The first connecting flange 32 is adapted to the flange assembly 9. An inlet 33 and an outlet 34 are respectively provided at the upper and lower ends of the first protective shell 31. A first baffle 35 is arranged inside the first protective shell 31; the sealing assembly 4 includes a second protective shell 41 and a second connecting flange 42. The second connecting flange 42 is adapted to the flange assembly 9. A second baffle 43 having the same position as the first baffle 35 is arranged inside the second protective shell 41.

[0024] During use, the inlet 33 is opened. The heat exchange pipes 2 are divided into upper and lower parts by the first baffle 35. The liquid to be heat-exchanged enters the interior of the upper heat exchange pipes 2 from the inlet 33. At this time, the coolant inlet 6 is also opened simultaneously. The coolant enters the interior of the housing 1 and contacts the heat exchange pipes 2. Since there are multiple heat exchange pipes 2, the contact area is wide and the heat exchange efficiency is high. At this time, the liquid to be heat-exchanged enters the interior of the sealing assembly 4 after the primary heat exchange. The second baffle 43 in the sealing assembly 4 has the same position as the first baffle 35 but does not completely block the upper and lower heat exchange pipes 2. Therefore, the liquid to be heat-exchanged will enter the lower heat exchange pipes 2 from the upper heat exchange pipes 2, thereby enabling secondary contact heat exchange with the coolant and further improving the heat exchange efficiency. Then, it flows out from the outlet 34 at the bottom of the water inlet and outlet assembly 3 to complete the heat exchange operation, and the coolant flows out from the coolant outlet 7 for recycling.

[0025] There are symmetrical hanging ear components 8 arranged on the top of the outer shell 1, which facilitates the hoisting and handling of the overall equipment by objects such as cranes; the heat exchange mechanism includes two flange components 9 arranged at the ends, and the flange components 9 are adapted to the water inlet and outlet components 3 and the closing components 4, which facilitates the disassembly and installation at both ends; a support base 10 is arranged at the bottom of the heat exchange mechanism, and the overall pipeline is placed on the workbench to prevent damage to the outer shell 1 and the like.

[0026] The above-described embodiments are only preferred embodiments given to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are within the protection scope of the present invention. The protection scope of the present invention is subject to the claims.
