Description

Technical Field

[0001] This application relates to the field of steam emission, and in particular to a steam emission mechanism with gas-liquid separation. Background Technology

[0002] In cooked food production, key processes such as steaming, sterilization, thawing, and drying all rely on steam as a heat source. Steam venting is a crucial step in ensuring process continuity and safety: on the one hand, venting allows for the timely removal of condensate and low-quality steam, maintaining stable system pressure and preventing water hammer damage to equipment; on the other hand, proper venting prevents excessive steam accumulation that could lead to uncontrolled temperature and humidity in the workshop, ensuring uniform product cooking and thorough sterilization, while also reducing energy consumption and meeting the hygiene and energy efficiency standards for food processing.

[0003] In the production of cooked food, the steam contains a high moisture content. Existing steam emission equipment generally uses a fan to extract the steam, which cannot separate the high moisture content in the steam, easily leading to substandard emissions and waste. Summary of the Invention

[0004] In order to improve the technical problem of steam emission without gas-liquid separation in cooked food production, this application provides a steam emission mechanism with gas-liquid separation.

[0005] The steam emission mechanism with gas-liquid separation provided in this application adopts the following technical solution:

[0006] A steam emission mechanism with gas-liquid separation includes a centrifugal fan equipped with a drive motor. The air inlet of the centrifugal fan is connected to an air inlet pipe, and the end of the air inlet pipe is connected to an air suction hood. The air outlet of the centrifugal fan is connected to an exhaust pipe, and the bottom of the exhaust pipe is connected to a water collection tank that is internally connected to the exhaust pipe. The bottom of the water collection tank is connected to a first drain pipe. The water collection tank contains inclined cold water plates, each composed of multiple parallel thin water pipes. The lower end of the cold water plate is connected to a water inlet pipe, and the upper end of the cold water plate is connected to a water outlet pipe.

[0007] By adopting the above technical solution, the centrifugal fan draws air from the inlet pipe and discharges air from the exhaust pipe. The suction hood is set at the top of the steam generation source. Steam enters from the suction hood and moves downward along the cold water plate when passing through the water collection tank. It passes through the bottom of the cold water plate and, upon contact with the cold water plate, the continuously flowing cold water in the plate condenses the moisture in the steam into water droplets, which are then discharged downward through the first drain pipe. Gas-liquid separation is achieved while discharging steam.

[0008] Preferably, a U-shaped water trough is provided below the bottom edge of the air intake hood, and an installation plate is provided between the side end of the U-shaped water trough and the outer side of the air intake hood, and a second drain pipe is connected to the lower end of the U-shaped water trough.

[0009] By adopting the above technical solution, water droplets will condense on the inner wall of the air intake hood when steam passes through, and the U-shaped water tank can gather the water droplets together and collect them in a centralized manner through the second drain pipe.

[0010] Preferably, the exhaust pipe has an installation port on its upper side, and first connecting plates are provided on both sides of the installation port. A positioning element is provided in the installation port, and an arc-shaped groove matching the water outlet pipe is provided at the bottom of the positioning element. Second connecting plates are provided on both sides of the positioning element, and the second connecting plates are connected to the first connecting plates by bolts. A first connecting flange is provided at the side end of the water outlet pipe, and several connecting bolt holes are provided on the first connecting flange. A connecting pipe is provided on the outside of the water collection tank, and a second connecting flange is provided on the connecting pipe. The second connecting flange is connected to the first connecting flange by bolts.

[0011] By adopting the above technical solution, the arc-shaped groove at the bottom of the positioning component can abut against the water outlet pipe, which can stabilize the cold water plate on the one hand, and reduce the gap above the cold water plate on the other hand, ensuring that the steam moves along the cold water plate. Moreover, it can be installed from the outside, making installation and disassembly more convenient.

[0012] Preferably, the inside of the water collection tank is fixed with a first guide plate and a second guide plate, which are located on both sides of the cold water plate, respectively.

[0013] By adopting the above technical solution, the space of the water tank is restricted by the first guide plate and the second guide plate, which restricts the flow path of the steam, so that the steam can fully contact the cold water plate during the flow.

[0014] Preferably, a third drain pipe is connected to the bottom of the centrifugal fan.

[0015] By adopting the above technical solution, condensate will be generated in both the air intake pipe and the centrifugal fan. The condensate in the air intake pipe enters the centrifugal fan along with the steam and can be discharged through the third drain pipe together with the condensate in the centrifugal fan.

[0016] Preferably, a wind baffle is fixed to the bottom inner side of the water collection tank, and the wind baffle is located directly above the first drain pipe. A water flow hole is opened at the lower end of the wind baffle, and a curved plate is connected to the bottom of the second guide plate, and the curved plate is located above the water flow hole.

[0017] By adopting the above technical solution, when the steam flows above the first drain pipe, it is blocked by the baffle plate and will not rush into the first drain pipe. Moreover, under the guidance of the curved plate, the steam will flow upward along the baffle plate, while the condensate can enter the first drain pipe through the water outlet.

[0018] Preferably, the second guide plate has a mounting groove in the middle, a rotating shaft is provided in the middle of the mounting groove, a plurality of circumferentially distributed rotating plates are fixed on the rotating shaft, and a soft scraper is installed on the side of the rotating plate away from the rotating shaft.

[0019] By adopting the above technical solution, the flow of steam will drive the rotating plate to rotate along the rotating shaft. On the one hand, it can disrupt the airflow and make the steam contact with the cold water plate more evenly. On the other hand, it can drive the soft scraper to scrape off the condensate on the surface of the cold water plate, thereby improving the cooling effect of the cold water plate.

[0020] Preferably, a flexible connecting sleeve is provided between the centrifugal fan and the air inlet pipe.

[0021] By adopting the above technical solution, the flexible connecting sleeve can reduce the vibration transmission between the centrifugal fan and the air inlet pipe, and prevent the joint from loosening and leaking water.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The steam is cooled by a continuously circulating cold water plate, which accelerates the condensation of water vapor and improves the gas-liquid separation effect. The condensate is discharged through the first drain pipe for centralized collection and treatment, which improves the emission standards and realizes the recycling of condensate.

[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0032] This application discloses a steam emission mechanism with gas-liquid separation.

[0033] Example 1:

[0034] Reference Figures 1-5 A steam emission mechanism with gas-liquid separation includes a centrifugal fan 1, a drive motor 2 for driving the centrifugal fan 1 is arranged on the side of the centrifugal fan 1, a third drain pipe 19 is connected to the bottom of the centrifugal fan 1, a flexible connecting sleeve 29, an air inlet pipe 3 and an air suction hood 5 are connected sequentially to the air inlet of the centrifugal fan 1, an exhaust pipe 4 is connected to the air outlet of the centrifugal fan 1, an internally interconnected water collection tank 6 is connected to the bottom of the exhaust pipe 4, a first drain pipe 10 is connected to the bottom of the water collection tank 6, and inclined cold water plates 7 are arranged inside the water collection tank 6. The cold water plates 7 are composed of multiple parallel connected thin water pipes, and a water inlet pipe 8 is connected to the lower end of the cold water plates 7. The upper end is connected to a water outlet pipe 9. An installation port is opened on the upper side of the exhaust pipe 4. A positioning component 17 is provided in the installation port. An arc-shaped groove matching the water outlet pipe 9 is opened at the bottom of the positioning component 17. A first connecting plate 16 is provided on both sides of the installation port. A second connecting plate 18 is provided on both sides of the positioning component 17. The second connecting plate 18 is connected to the first connecting plate 16 by bolts. A first connecting flange 14 is provided on the side end of the water outlet pipe 9. Several connecting bolt holes are opened on the first connecting flange 14. A connecting pipe 15 is provided on the outside of the water collection tank 6. A second connecting flange is provided on the connecting pipe 15. The second connecting flange is connected to the first connecting flange 14 by bolts.

[0035] With the above setup, steam is drawn into the suction hood 5 and passes sequentially through the intake pipe 3, centrifugal fan 1, exhaust pipe 4, and water collection tank 6. The steam generates condensate in the suction hood 5 and centrifugal fan 1, which can be discharged through the third drain pipe 19. When the steam passes through the water collection tank 6, the steam moves downward along the cold water plate 7 and passes through the bottom of the cold water plate 7. When it comes into contact with the cold water plate 7, the continuously flowing cold water in the cold water plate 7 will condense the moisture in the steam into water droplets, which are then discharged downward through the first drain pipe 10. At the same time as the steam is discharged, gas-liquid separation is achieved.

[0036] Furthermore, the arc-shaped groove at the bottom of the positioning component 17 can abut against the water outlet pipe 9, which can stabilize the cold water plate 7 on the one hand, and reduce the gap above the cold water plate 7 on the other hand, ensuring that the steam moves along the cold water plate 7.

[0037] Reference Figure 6 A U-shaped water trough 11 is provided below the lower edge of the suction hood 5, and the bottom of the suction hood 5 is completely located inside the U-shaped water trough 11. The side end of the U-shaped water trough 11 is connected and fixed to the outside of the suction hood 5 by a mounting plate 12. The lower end of the U-shaped water trough 11 is connected to a second drain pipe 13.

[0038] With the above configuration, the U-shaped water tank 11 can collect the condensate that slides down the inner wall of the air intake hood 5 and discharge it through the second drain pipe 13, thus recycling and preventing condensate from dripping and reducing product quality.

[0039] The implementation principle of this application embodiment is as follows:

[0040] Steam is discharged by centrifugal fan 1. Condensate is collected in three steps during the discharge process. First, the condensate that slides down the inner wall of the suction hood 5 is collected by the U-shaped water tank 11 and discharged through the second drain pipe 13. Then, the condensate generated in the suction hood 5 and centrifugal fan 1 is discharged through the third drain pipe 19. Finally, when the steam passes through the water collection tank 6, the steam moves downward along the cold water plate 7 and passes through the bottom of the cold water plate 7. When it comes into contact with the cold water plate 7, the continuously flowing cold water in the cold water plate 7 condenses the moisture in the steam into water droplets, which are discharged downward through the first drain pipe 10. Through three drainages, gas-liquid separation is achieved while the steam is being discharged.

[0041] Example 2:

[0042] refer to Figure 2 and Figure 4Inside the water tank 6, there are a first guide plate 20 and a second guide plate 21 located on both sides of the cold water plate 7. The second guide plate 21 has an installation groove 25 in the middle, and a rotating shaft 26 is rotatably installed in the middle of the installation groove 25. Several rotating plates 27 are evenly distributed around the circumference and fixed on the rotating shaft 26. A soft scraper 28 is installed on the side of the rotating plate 27 away from the rotating shaft 26.

[0043] With the above configuration, the first guide plate 20 and the second guide plate 21 restrict the flow path of the steam, allowing the steam to make more thorough contact with the cooling water plate 7. Furthermore, the steam flow can drive the rotating plate 27 to rotate, which on the one hand disrupts the airflow, making the contact between the steam and the cooling water plate 7 more uniform; on the other hand, it can drive the soft scraper 28 to scrape away the condensate on the surface of the cooling water plate 7, improving the cooling effect of the cooling water plate 7.

[0044] A baffle plate 22 is fixed to the bottom of the inner side of the water collection tank 6, and the baffle plate 22 is located directly above the first drain pipe 10. A water flow hole 24 is opened at the lower end of the baffle plate 22. A curved plate 23 is connected to the bottom of the second guide plate 21, and the curved plate 23 is located above the water flow hole 24.

[0045] With the above configuration, the baffle plate 22 can prevent steam from rushing into the first drain pipe 10. With the guiding effect of the curved plate 23, the steam will flow upward along the baffle plate 22, while the condensate can enter the first drain pipe 10 through the drain hole 24.

[0046] The implementation principle of this application embodiment is as follows:

[0047] The steam moves along the cold water plate 7 through the first guide plate 20 and the second guide plate 21, fully separating the condensate. The condensate can flow into the first drain pipe 10 through the water outlet 24, while the steam will continue to flow upward along the wind baffle 22 and the first guide plate 20 under the guidance of the curved plate 23.

[0048] In summary, this device can collect condensate multiple times during the steam emission process, accelerate the condensation of water vapor, optimize the gas-liquid separation effect, thereby improving emission standards and reducing waste.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
