Description

Technical Field

[0001] This utility model belongs to the field of gas-liquid separation technology of marine power systems, and specifically relates to a gas-water separator structure for marine heat exchangers. Background Technology

[0002] In marine propulsion systems, heat exchangers (air coolers) are used to cool the heat generated in the engine room, ensuring that the temperature inside the engine room meets the equipment operating requirements. Due to the high humidity of the marine environment, condensate will be generated in the heat exchanger during the cooling process. If this condensate diffuses into the engine room with the airflow, it will pose a serious threat to the normal operation and safety of the equipment inside. Therefore, a gas-liquid separator needs to be installed on the outlet side of the heat exchanger to achieve gas-liquid separation based on the principle of inertial separation.

[0003] The mainstream inertial air-water separators on the market currently use corrugated or hooked water separator plates. Corrugated water separator plates have a small contact area with the gas, resulting in weaker separation performance. Although hooked water separator plates increase the contact area and improve the separation effect by adding water-retaining grooves, their molding process is complex and difficult to produce. Furthermore, both types of water separator plates suffer from insufficient strength and are prone to cracking under conditions of large air volumes and humid air, affecting the structural stability of the separator. Utility Model Content

[0004] The purpose of this utility model is to provide a marine heat exchanger gas-water separator structure to solve the problems mentioned in the background art, such as limited water separation efficiency, insufficient structural strength, and inconvenient maintenance of existing inertial gas-water separators.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a marine heat exchanger gas-water separator structure, comprising a fixed frame and multiple water-distributing plates disposed within the fixed frame. The fixed frame is composed of four bent plates spliced ​​together. The water-distributing plates are integrally bent and formed, with one end of the water-distributing plate having an arc-shaped structure. The front and rear sides of the water-distributing plates are provided with reinforcing ribs that are movably connected to the fixed frame. The side of the reinforcing rib facing the water-distributing plate has a slot that matches the water-distributing plate. A cavity is formed inside the reinforcing rib, and two fixing mechanisms are fixed inside the cavity of the reinforcing rib. A water collection tank is fixed on the surface of the lowest bent plate, and drainage holes are formed at corresponding positions of the water collection tank and the bent plate. A drainage pipe is fixed inside the drainage hole.

[0006] In a further embodiment, the fixing mechanism consists of a fixing block and a fixing pin. The fixing block is fixed in the cavity of the reinforcing rib. The fixing block has a moving hole for the fixing pin to move. The fixing pin extends out of the reinforcing rib. The opposing surfaces of the two bending plates each have a plurality of fixing holes that match the fixing pin.

[0007] In a further embodiment, a movable block extending below the bending plate is fixed to the outer wall of the fixing pin, and a fixing spring for supporting the movable block is sleeved on the outside of the fixing pin.

[0008] In a further embodiment, a magnetic ring is adsorbed on the surface of the drain pipe, and a filter screen is installed inside the magnetic ring.

[0009] In a further embodiment, the fixing block has multiple rolling grooves, and the rolling grooves of the fixing block are connected to sliding balls that are in contact with the fixing pin.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] The gas-liquid separator structure of this marine heat exchanger features a water separator plate that is integrally bent and has an arc-shaped structure at one end. Compared with the traditional wave-shaped water separator plate, it increases the contact area with the humid airflow. When the airflow flows through the arc-shaped surface, the droplets in it will be subjected to stronger inertial and centrifugal forces, which will cause them to quickly impact and adhere to the surface of the water separator plate, and then collect to form a liquid film. This effectively solves the problem of weak separation performance of the traditional structure, and the gas-liquid separation is more thorough.

[0012] Reinforcing ribs are provided on both the front and rear sides of the water distributor. They are precisely engaged with the water distributor through slots, forming a two-way support for the water distributor. Combined with the water distributor's own one-piece bending molding process, it avoids the defect of traditional water distributors being prone to cracking under high air volume and humid air conditions. At the same time, the reinforcing ribs are firmly connected to the fixed frame through the fixing mechanism, which further improves the stability of the overall structure and extends the service life.

[0013] The fixing mechanism inside the reinforcing rib adopts a combination design of fixing pin, moving block and fixing spring. Pressing the moving block can drive the fixing pin to disengage from the fixing hole of the bending plate, and quickly disassemble the reinforcing rib and water separator plate, which is convenient for later cleaning and replacement of parts. The magnetic ring adsorption filter screen on the drain pipe can be directly removed for cleaning, avoiding blockage of the drain hole and reducing maintenance difficulty. The gas-water separator structure of this marine heat exchanger solves the problems of limited separation efficiency, insufficient structural strength and inconvenient maintenance of the existing gas-water separator water separator plate.

[0022] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0023] This utility model provides, for example Figure 1-5 The structure of a marine heat exchanger gas-water separator shown includes a fixed frame and multiple water-distributing plates 2 disposed within the fixed frame. The fixed frame is composed of four bent plates 1 spliced ​​together, and the contact positions of the four bent plates 1 are fixed by bolts. The water-distributing plates 2 are integrally bent and formed, and one end of the water-distributing plate 2 has an arc-shaped structure. The front end of the water-distributing plate 2 is the windward side. The front and rear sides of the water-distributing plate 2 are provided with reinforcing ribs 3 that are movably connected to the fixed frame. The side of the reinforcing rib 3 facing the water-distributing plate 2 has a slot that matches the water-distributing plate 2. The water-distributing plate 2 is snapped into the slot of the reinforcing rib 3, which can restrict the position of the water-distributing plate 2. At the same time, the reinforcing ribs 3 on the front and rear sides of the water-distributing plate 2 can improve the strength of the water-distributing plate 2. The reinforcing rib 3 has a cavity, and two fixing mechanisms are fixed in the cavity of the reinforcing rib 3.

[0024] The fixing mechanism consists of a fixing block 4 and a fixing pin 5. The fixing block 4 is fixed inside the cavity of the reinforcing rib 3. The fixing block 4 has a moving hole for the fixing pin 5 to move. The fixing pin 5 extends outside the reinforcing rib 3. The opposite surfaces of the two bent plates 1 each have multiple fixing holes that match the fixing pin 5. The fixing block 4 has multiple rolling grooves, and the rolling grooves of the fixing block 4 are connected to sliding balls 6 that fit against the fixing pin 5. The sliding balls 6 enable the fixing pin 5 to move more smoothly inside the fixing block 4. The outer wall of the fixing pin 5 is fixed with a moving block 7 extending to the bottom of the bent plate 1. The bottom of the reinforcing rib 3 has two... The movable slot allows the movable block 7 to move, and the fixed pin 5 is externally sleeved with a fixed spring 8 to support the movable block 7. The elastic force of the fixed spring 8 can be set according to actual usage requirements, which can stably support the movable block 7. By supporting the movable block 7 with the fixed spring 8, the fixed pin 5 is inserted into the fixed hole of the bending plate 1, which can fix the position of the reinforcing rib 3, further ensuring the stability of the positions of multiple water dividers 2. By moving the fixed pin 5 through the movable block 7, the fixed pin 5 is separated from the bending plate 1, which can quickly complete the disassembly of the reinforcing rib 3, making it easier to disassemble the water dividers 2 and making subsequent maintenance more convenient.

[0025] A water collection tank 9 is fixed to the surface of the bottom bending plate 1. The bottom wall of the inner cavity of the water collection tank 9 is provided with an inclined surface to guide the collected droplets. Drainage holes are opened at corresponding positions of the water collection tank 9 and the bending plate 1. A drain pipe 10 is fixed in the drain hole. A magnetic ring 11 is adsorbed on the surface of the drain pipe 10, and a filter screen 12 is installed inside the magnetic ring 11. The filter screen 12 inside the magnetic ring 11 can filter the collected droplets and prevent the drain pipe 10 from being blocked. All components of this device are treated with rust prevention and corrosion prevention to adapt to the high humidity and high salt spray characteristics of the marine environment and extend the service life. During use, the airflow enters the water separator 2 and flows along the arc surface of the water separator 2. Under the action of inertial force and centrifugal force, the droplets hit the arc surface and gather along the arc surface to form a liquid film. The liquid film flows into the water collection tank 9 at the bottom under the action of gravity and is finally discharged through the drain pipe 10.

[0028] Working principle:

[0029] The gas-liquid separator structure of this marine heat exchanger has a fixed frame installed on the outlet side of the air heat exchanger. After the humid airflow enters the gas-liquid separator from the outlet side of the heat exchanger, it flows through multiple arc-shaped water-distributing plates 2 within the fixed frame. As the airflow flows along the arc-shaped surface of the water-distributing plates 2, under the combined action of inertial force and centrifugal force, the condensate droplets carried in the airflow are thrown towards the surface of the water-distributing plates 2 and collide. Subsequently, the droplets gradually gather on the surface of the water-distributing plates 2 to form a continuous liquid film. Under the action of its own gravity, the liquid film flows downward along the surface of the water-distributing plates 2 and finally flows into the water collection tank 9 at the bottom. The inclined surface in the water collection tank 9 guides the condensate to converge towards the drain hole and is discharged outside the separator through the drain pipe 10. At the same time, the filter screen 12 in the magnetic ring 11 on the drain pipe 10 can filter impurities in the water to prevent the drain hole from being blocked, thus realizing continuous and stable operation of gas-liquid separation and directional drainage. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
