Description

Technical Field

[0001] This application relates to the field of evaporation equipment technology, and in particular to a gas-liquid separation device for an evaporation chamber. Background Technology

[0002] In the evaporation process, the evaporation chamber is one of the core pieces of equipment. Inside, heating causes the moisture in the material to evaporate, generating secondary steam. This secondary steam tends to carry some liquid droplets as it rises. If this secondary steam directly enters the subsequent heater or condensation system, it will affect heat transfer efficiency, increase energy consumption, and even lead to a decrease in product purity. Therefore, installing a gas-liquid separation device at the top of the evaporation chamber is crucial for improving the overall performance of the evaporation system.

[0003] Currently, most commonly used gas-liquid separation devices in evaporation chambers adopt a baffle structure, which separates liquid droplets by changing the airflow direction.

[0004] Regarding the aforementioned technologies, the inventors believe that the separation of droplets in the secondary steam by the baffle is incomplete, and the secondary steam still carries a large number of droplets, resulting in a decrease in the heat exchange efficiency of the subsequent heater. Utility Model Content

[0005] The purpose of this application is to provide an evaporation chamber gas-liquid separation device to improve the problem that the secondary steam still carries a lot of liquid droplets, which leads to a decrease in the heat exchange efficiency of the subsequent heater.

[0006] The gas-liquid separation device for the evaporation chamber provided in this application adopts the following technical solution: An evaporation chamber gas-liquid separation device includes an evaporation chamber body and a separation chamber disposed on the top of the evaporation chamber body. The separation chamber is connected to the interior of the evaporation chamber body. The top of the evaporation chamber body is provided with a mounting tube seat corresponding to the interior of the separation chamber. The mounting tube seat has a mounting groove that communicates with the gas outlet of the evaporation chamber body. A wire mesh demister is disposed in the mounting groove. The side wall of the separation chamber is connected to a gas outlet pipe that communicates with a heater. A guide plate is disposed around the mounting tube seat on the inner side wall of the separation chamber.

[0007] By adopting the above technical solution, a separation chamber connected to the top of the evaporation chamber body is set up to provide an independent space for gas-liquid separation. The wire mesh demister in the mounting tube serves as the core separation element, which can directly intercept liquid droplets in the secondary steam. The guide plate in the separation chamber can guide the steam flow along a preset path to ensure that the steam flows orderly through the wire mesh demister and from the outlet pipe to the heater, thus ensuring the stability of gas-liquid separation.

[0008] Optionally, the guide plate is arranged in a ring around the mounting tube seat, and a flow channel is formed between the guide plate and the side wall of the mounting tube seat and the side wall of the separation cavity.

[0009] By adopting the above technical solution, the guide plate is arranged in a ring around the mounting pipe seat, so that it, together with the side wall of the mounting pipe seat and the side wall of the separation chamber, forms a guide channel. This allows the secondary steam to flow through the guide channel into the outlet pipe after passing through the wire mesh demister, preventing the steam from forming turbulence or eddies in the separation chamber after passing through the wire mesh demister.

[0010] Optionally, the height of the guide plate is higher than the height of the mounting base, so that the guide plate and the mounting base are staggered, causing the guide channel to bend multiple times.

[0011] By adopting the above technical solution, the height of the guide plate is higher than the height of the mounting pipe seat, so that the guide channel forms a multiple bending structure. The bending guide channel can change the airflow direction and generate inertial force, causing the liquid droplets carried in the steam to collide with the guide plate or the side wall of the mounting pipe seat under the action of inertia. This causes the liquid droplets remaining in the steam to collide with the guide plate and condense into large liquid droplets, which further improves the overall effect of gas-liquid separation.

[0012] Optionally, the inner wall of the mounting groove is provided with an annular plate that abuts against the bottom of the wire mesh demister, and a sealing layer is provided between the inner wall of the mounting groove and the wire mesh demister.

[0013] By adopting the above technical solution, the ring plate on the inner side wall of the mounting tank supports the wire mesh demister, ensuring that the wire mesh demister maintains structural stability under the impact of airflow and avoiding the separation gap from increasing due to vibration; the sealing layer between the inner side wall of the mounting tank and the wire mesh demister eliminates the gap between the two, preventing steam from flowing through the gap without being intercepted by the wire mesh demister, and ensuring that all steam is separated by the wire mesh demister.

[0014] Optionally, a drain pipe is provided inside the separation chamber at the top of the evaporation chamber body, and the drain pipe passes through the side wall of the evaporation chamber body and faces into the evaporation chamber body.

[0015] By adopting the above technical solution, the drain pipe located at the top of the evaporation chamber body inside the separation chamber penetrates the side wall and faces into the evaporation chamber body. The droplets carried in the steam, under the action of inertia, hit the guide plate or the side wall of the mounting pipe seat and drip down. The droplets then return to the evaporation chamber body through the drain pipe, draining the water accumulated in the separation chamber back into the evaporation chamber.

[0016] Optionally, the drain pipe extends inside the evaporation chamber body and is provided with an arc-shaped pipe. The curved part of the arc-shaped pipe faces the bottom of the evaporation chamber body and there is enough liquid inside the arc-shaped pipe to prevent air leakage.

[0017] By adopting the above technical solution, the drain pipe is an arc-shaped pipe extending inside the evaporation chamber body, with its curved part facing the bottom of the evaporation chamber body. Sufficient liquid is reserved in the pipe to form a water seal structure. The sealing property of the liquid blocks the path of steam leakage from the drain pipe, preventing steam from being lost from the drain channel due to pressure difference during the separation process. At the same time, it does not affect the liquid being discharged back into the evaporation chamber under the action of gravity. While ensuring the gas-liquid separation effect, it improves the sealing performance and energy utilization efficiency of the system and reduces steam loss.

[0018] Optionally, the top of the evaporation chamber body is arranged in a convex arc shape outside the mounting pipe seat, and the arc-shaped pipe is arranged along the connection position between the inner wall of the separation chamber and the evaporation chamber body.

[0019] By adopting the above technical solution, the top of the evaporation chamber body is set in a convex arc shape outside the mounting tube seat, so that the droplets dripping from the inner wall of the separation chamber and the side wall of the guide plate gather at the connection between the evaporation body and the separation chamber and are discharged from the drain pipe, reducing the possibility of water remaining in the separation chamber for a long time.

[0020] Optionally, the top of the separation chamber is provided with a detachable sealing plate fixed with bolts, the guide plate is connected to the sealing plate, and the top of the sealing plate is provided with a handle.

[0021] By adopting the above technical solution, the detachable sealing plate at the top of the separation chamber is fixed with bolts, which facilitates disassembly and assembly. The guide plate is connected to the sealing plate, so that the guide plate can be moved synchronously when the sealing plate is disassembled and assembled, which facilitates the cleaning, replacement or maintenance of components such as the wire mesh demister and guide plate inside the separation chamber.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a separation chamber connected to the top of the evaporation chamber body, an independent space is provided for gas-liquid separation. The wire mesh demister in the mounting tube serves as the core separation element, which can directly intercept liquid droplets in the secondary steam. The guide plate in the separation chamber can guide the steam flow along a preset path, ensuring that the steam flows orderly through the wire mesh demister and from the outlet pipe to the heater, thus ensuring the stability of gas-liquid separation. 2. The ring plate on the inner side wall of the installation tank supports the wire mesh demister, ensuring that the wire mesh demister remains structurally stable under the impact of airflow and preventing the separation gap from increasing due to vibration; the sealing layer between the inner side wall of the installation tank and the wire mesh demister eliminates the gap between the two, preventing steam from flowing through the gap without being intercepted by the wire mesh demister, and ensuring that all steam is separated by the wire mesh demister. 3. The drain pipe is an arc-shaped pipe extending inside the evaporation chamber body. Its curved part faces the bottom of the evaporation chamber body, and the pipe is filled with liquid of sufficient height to form a water seal structure. The sealing property of the liquid blocks the path of steam leakage from the drain pipe, preventing steam from being lost from the drain channel due to pressure difference during the separation process. At the same time, it does not affect the liquid being discharged back into the evaporation chamber under the action of gravity, thus reducing steam loss. Attached Figure Description

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0026] Evaporation chamber gas-liquid separation device, refer to Figure 1 and Figure 2 The system includes an evaporator body 1 and a separation chamber 2 welded to the top of the evaporator body 1. A mounting pipe seat 3 corresponding to the interior of the separation chamber 2 is welded at the air outlet position on the top of the evaporator body 1. An installation groove 31 communicating with the air outlet of the evaporator body 1 is opened in the mounting pipe seat 3. A wire mesh demister 4 is fixed in the installation groove 31 with bolts. When the secondary steam flows through the wire mesh demister 4, the droplets are intercepted by the wire mesh and condensed into liquid droplets, which can directly intercept the droplets in the secondary steam. An air outlet pipe 21 connecting to the heater is welded to the side wall of the separation chamber 2. A guide plate 22 is arranged around the mounting pipe seat 3 on the inner side wall of the separation chamber 2. A detachable sealing plate 26 fixed with bolts is arranged on the top of the separation chamber 2. The guide plate 22 and the sealing plate 26 are welded together. A handle 27 is welded to the top of the sealing plate 26. A sealing gasket is adhered between the sealing plate 26 and the separation chamber 2 for sealing.

[0027] Reference Figure 2 and Figure 3The guide plate 22 is arranged in a ring around the mounting pipe seat 3, and a guide channel 23 is formed between the guide plate 22 and the side wall of the mounting pipe seat 3 and the side wall of the separation chamber 2. The height of the guide plate 22 is higher than that of the mounting pipe seat 3, so that the guide plate 22 and the mounting pipe seat 3 are staggered, and the guide channel 23 bends multiple times. This causes the liquid droplets carried in the steam to collide with the guide plate 22 or the side wall of the mounting pipe seat 3 under the action of inertia, and causes the liquid droplets remaining in the steam to collide with the guide plate 22 and condense into large liquid droplets, which further improves the overall effect of gas-liquid separation.

[0028] Reference Figure 2 and Figure 3 A ring plate 24 is welded to the inner wall of the mounting groove 31 of the mounting pipe seat 3, which abuts against the bottom of the wire mesh demister 4. The top surface of the ring plate 24 abuts against the bottom of the wire mesh demister 4, providing support for the wire mesh demister 4. A rubber sealing gasket 55 is bonded between the inner wall of the mounting groove 31 and the wire mesh demister 44 to eliminate the gap between them.

[0029] Reference Figure 2 and Figure 3 Inside the separation chamber 2, at the top of the evaporation chamber body 1, there is a drain pipe 6. One end of the drain pipe 6 extends into the separation chamber 2, and the other end passes through the side wall of the evaporation chamber body 1 and faces into the evaporation chamber body 1. The part of the drain pipe 6 inside the evaporation chamber body 1 is welded with an arc-shaped pipe 61. The curved part of the arc-shaped pipe 61 faces the bottom of the evaporation chamber body 1, and there is a sufficient height of liquid reserved in the arc-shaped pipe 61 to form a water seal to prevent air leakage. The top of the evaporation chamber body 1 is in the shape of a convex arc outside the mounting pipe seat 3. The arc-shaped pipe 61 is set along the connection position between the inner side wall of the separation chamber 2 and the evaporation chamber body 1, so that the droplets dripping from the inner side wall of the separation chamber 2 and the side wall of the guide plate 22 collect at the connection position between the evaporation body and the separation chamber 2 and are discharged from the drain pipe 6, reducing the possibility of water remaining in the separation chamber 2 for a long time.

[0030] The implementation principle of this application embodiment is as follows: The secondary steam generated by the evaporation chamber body 1 enters the separation chamber 2 through the mounting pipe seat 3 at the outlet. When it flows through the wire mesh demister 4, the droplets are intercepted by the wire mesh and condense into liquid droplets. The liquid droplets fall back into the evaporation chamber body 1 under the action of gravity. Then it enters the annular guide channel 23 formed by the mounting pipe seat 3 and the guide plate 22. Since the guide plate 22 is higher than the mounting pipe seat 3, the steam needs to flow along the curved guide channel 23. During the flow, the change in direction generates inertial force. Some of the residual liquid droplets in the steam collide with the guide plate 22 or the side wall of the mounting pipe seat 3 and then converge and drip. After converging, they are discharged back into the evaporation chamber body 1 through the drain pipe 6 along the inner side wall of the separation chamber 2, ensuring the stability of gas-liquid separation and preventing the liquid droplets carried in the secondary steam from affecting the heat exchange efficiency of the heater.
