Abstract
Description
Technical Field
[0001] This utility model relates to the field of shell-and-tube condenser technology, and in particular to a shell-and-tube condenser structure. Background Technology
[0002] A condenser is a device that uses the property of steam or gas to condense upon contact with cold air. It achieves condensation by exchanging heat between the gas in the condenser tube and the cooling liquid or gas outside the tube and carrying away the heat. Condensers generally use tubular condenser tubes and achieve condensation by flushing the condenser tube with cooling liquids such as cold water.
[0003] When using a condenser to dissipate heat and condense high-temperature gas, the high-temperature gas is introduced into the condenser. Due to the high flow rate of the introduced high-temperature gas, the flow speed of the high-temperature gas in the condenser is fast, resulting in a short heat dissipation and condensation time for the high-temperature gas, thereby reducing the heat dissipation and condensation effect of the high-temperature gas. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where high-temperature gas flows rapidly within the condenser, resulting in a short condensation time and reduced heat dissipation efficiency. Therefore, this invention proposes a shell-and-tube condenser structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A shell-and-tube condenser structure is designed, including a condenser shell. A first partition is fixedly connected to one side of the condenser shell, forming a first chamber between the first partition and the inner wall of the condenser shell. A second partition is fixedly connected to the other side of the condenser shell, forming a second chamber between the second partition and the inner wall of the condenser shell. A condensation mechanism is connected between the first partition and the second partition. An inlet pipe is connected to the first chamber, and an outlet pipe is connected to the second chamber. A liquid inlet pipe is connected to the upper end of the condenser shell, and a liquid drain pipe is connected to the bottom end of the condenser shell. A buffer mechanism for gas deceleration is connected inside the first chamber.
[0007] The buffer mechanism includes a perforated plate, which is fixedly connected to the first chamber. Several buffer plates are connected to the perforated plate, and each buffer plate has several air holes.
[0008] Preferably, the condenser shell is coated with an anti-corrosion layer.
[0009] Preferably, the buffer plate is an arc-shaped plate.
[0010] Preferably, the condensation mechanism includes a plurality of condenser tubes, all of which are connected between the first partition and the second partition, and each condenser tube is connected with a plurality of heat dissipation plates at equal intervals along the axial direction.
[0011] Preferably, the condenser is a stainless steel condenser, and the condenser and the heat sink are an integral structure.
[0012] Preferably, each of the heat sinks has heat dissipation holes, and the heat dissipation holes are distributed at equal intervals along the length direction.
[0013] The shell-and-tube condenser structure proposed in this utility model has the following advantages:
[0014] The high-temperature gas entering the first chamber comes into contact with the buffer plate, which buffers and slows down the gas. After slowing down, the high-temperature gas passes through the vent and the perforated plate in sequence before entering the condensation mechanism. This reduces the flow velocity of the high-temperature gas entering the condensation mechanism, thereby prolonging the contact time between the high-temperature gas and the condensation mechanism and improving the condensation effect of the high-temperature gas.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Example 1: Refer to Figure 1-3 A shell-and-tube condenser structure includes a condenser shell 1, which is coated with an anti-corrosion layer. A first partition 2 is fixedly connected to one side of the interior of the condenser shell 1, forming a first chamber 3 between the first partition 2 and the inner wall of the condenser shell 1. A second partition 5 is fixedly connected to the other side of the interior of the condenser shell 1, forming a second chamber 6 between the second partition 5 and the inner wall of the condenser shell 1. A condensation mechanism 8 is connected between the first partition 2 and the second partition 5. An inlet pipe 4 is connected to the first chamber 3, and an outlet pipe 7 is connected to the second chamber 6. A liquid inlet pipe 9 is connected to the upper end of the condenser shell 1, and a drain pipe 10 is connected to the bottom end of the condenser shell 1. A buffer mechanism 11 for gas deceleration is connected inside the first chamber 3.
[0023] The buffer mechanism 11 includes a perforated plate 112, which is fixedly connected to the first chamber 3. Several buffer plates 111 are connected to the perforated plate 112. The buffer plates 111 are arc-shaped plates, and each buffer plate 111 has several air holes.
[0024] Work process:
[0025] High-temperature gas enters the first chamber 3 through the inlet pipe 4. The high-temperature gas in the first chamber 3 comes into contact with the buffer plate 111, which buffers and slows down the high-temperature gas. After slowing down, the high-temperature gas passes through the air hole and the perforated plate 112 in sequence and enters the condensing mechanism 8. Coolant is introduced into the condenser shell 1 through the liquid inlet pipe 9. The coolant comes into contact with the condensing mechanism 8 and cools and condenses the high-temperature gas in the condensing mechanism 8. After the coolant in the condenser shell 1 is heated, it is released from the drain pipe 10. The high-temperature gas that has been cooled and condensed enters the second chamber 6 and is released from the outlet pipe 7. The buffer plate 111 and the perforated plate 112 buffer and slow down the high-temperature gas, reducing the flow speed of the high-temperature gas entering the condensing mechanism 8, thereby prolonging the contact time between the high-temperature gas and the condensing mechanism 8, and thus improving the condensation effect of the high-temperature gas.
[0026] Example 2: In Example 1, the high-temperature gas is cooled and condensed by the condensing mechanism 8. However, the contact area between the condensing mechanism 8 and the coolant is small, thus reducing the condensation effect on the high-temperature gas. (Refer to...) Figure 4-5As another preferred embodiment of this utility model, the difference from embodiment 1 is that the condensing mechanism 8 includes a plurality of condensing tubes 81, all of which are connected between the first partition 2 and the second partition 5. Each condensing tube 81 is connected with a plurality of heat dissipation plates 82 at equal intervals along the axial direction. The condensing tubes 81 are stainless steel condensing tubes, and the condensing tubes 81 and the heat dissipation plates 82 are integral structures. Each heat dissipation plate 82 is provided with heat dissipation holes 83, and the heat dissipation holes 83 are provided with a plurality of holes at equal intervals along the length direction. The heat dissipation plates 82 are fixed on the condensing tubes 81 to increase the contact area between the condensing tubes 81 and the coolant. At the same time, the heat dissipation holes 83 on the heat dissipation plates 82 improve the heat dissipation effect of the heat dissipation plates 82, thereby improving the condensing effect of the condensing tubes 81 on high-temperature gases.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
