[0024] The tray body 1 is the basic structure of the whole tray, providing installation and working platform for other components. It carries the flow of liquid and the gas-liquid mixing and mass transfer process. The overflow weir 2 is arranged at the top of the tray body 1, used to maintain the liquid level height on the tray body 1. When the liquid flows into the tray body 1, the overflow weir 2 blocks the liquid to accumulate to a certain height on the tray body 1, and then the liquid overflows from the top of the overflow weir 2 to the next layer of tray. It ensures that the liquid has enough residence time on the tray body 1, so that the gas-liquid can fully contact. The liquid receiving plate 3 is installed on the right side of the tray body 1, used to receive the liquid overflowing from the upper layer of tray, and evenly distribute it to the tray body 1 of the current layer, reducing the impact of the liquid on the tray body 1, so that the liquid enters the tray body 1 smoothly. It plays the role of buffering and uniform distribution of liquid, ensuring that the initial distribution of liquid on the tray body 1 is uniform, which is conducive to the good contact and mass transfer of gas-liquid. The installation groove 10 is arranged on the bottom surface of the tray body 1, providing installation space and movement track for the moving plate 4. The moving plate 4 moves up and down in the installation groove 10 through the limiting of the fixed plate 9 under the impact of steam. It limits the movement track and space of the moving plate 4, and ensures the relative position relationship between the moving plate 4 and other components, so that the whole self-adaptive adjusting system can work in order. When the steam volume increases to a certain extent, the impact force on the moving plate 4 is greater than the elastic force of the return spring 12, the moving plate 4 will move upwards. The movement of the moving plate 4 drives the second float valve 8 installed on it to move upwards and open, thereby changing the air volume of the second through hole 6. According to the change of steam volume, the position is automatically adjusted, and then the second float valve 8 is driven to act, realizing the adjustment of the air volume of the second through hole 6, to adapt to the fluctuation of feed flow. The first through hole 5 is evenly distributed on the surface of the tray body 1 and the moving plate 4, which is one of the main channels for the steam to rise. After the steam passes through the first through hole 5 of the moving plate 4, it enters the sleeve 11 inside the first through hole 5 of the moving plate 4, and impacts the first float valve 7 inside the sleeve 11. The first through hole 5 provides a flow path for the steam, so that the steam can mix with the liquid at the top of the tray body 1. The second through hole 6 is also evenly distributed on the surface of the tray body 1 and the moving plate 4, and corresponds to the position of the first through hole 5 one by one. When the moving plate 4 moves upwards, it drives the second float valve 8 installed on it to move upwards and open, and the air volume of the second through hole 6 increases, allowing more steam to pass through to adapt to larger flow of liquid. As another flow path for steam, its air volume can be adjusted according to the movement of the moving plate 4, and it works with the first through hole 5 to realize flexible control of steam flux, adapting to the change of feed flow. The first float valve 7 penetrates the first through hole 5 and the sleeve 11, and is clamped with the tray body 1. When there is steam rising, the steam passes through the first through hole 5 of the moving plate 4 and enters the sleeve 11, impacting the first float valve 7 and making it open upwards. The opening degree of the first float valve 7 increases with the increase of steam volume, thereby allowing more steam to pass through the first through hole 5 and mix with the liquid at the top of the tray body 1.According to the steam quantity automatic regulation opening, the steam quantity through the first through hole 5 is controlled, the preliminary regulation of the gas-liquid mixing degree is realized, the gas-liquid contact efficiency and mass transfer effect are improved. The second float valve 8 cooperates with the movement of the moving plate 4, further adjusts the steam flux, and cooperates with the first float valve 7 to ensure that when the feed flow fluctuates greatly, the tray can still maintain good gas-liquid contact and mass transfer effect, and maintain the stable operation of the tower. The two fixed plates 9 are mirror images arranged with the mounting groove 10 as the center, and are screwed to the tray body 1, used to fix the position of the moving plate 4 in the mounting groove 10, limit the moving range of the moving plate 4, so that it can only move up and down within a certain range, prevent the moving plate 4 from deviating or leaving the mounting groove 10 under the impact of steam. The sleeve 11 is internally provided with the first float valve 7, and the sleeve 11 is arranged at a position corresponding to the position where the first through hole 5 is arranged, and the sleeve 11 is integrally formed with the tray body 1. The sleeve 11 provides a relatively closed space for the first float valve 7, so that the steam can concentrate on impacting the first float valve 7, and ensure that the first float valve 7 is accurate and sensitive. The reset spring 12 is arranged outside the second float valve 8, and when the steam quantity decreases and the impact force on the moving plate 4 is less than the elastic force of the reset spring 12, the reset spring 12 pushes the moving plate 4 to move downward, so that the second float valve 8 is closed or the opening is reduced, and returns to the initial state. Specific embodiment two:

[0026] Reference Figures 1-4 A self-adaptive flow regulation tray further based on the basic structure in specific embodiment one, the overall working process is that when the steam rises from below the tray body 1, first enters the sleeve 11 through the first through hole 5 of the moving plate 4, impacts the first float valve 7 in the sleeve 11, makes the first float valve 7 open upward, and the steam mixes with the liquid at the top of the tray body 1 through the first through hole 5. With the increase of the steam quantity, the opening of the first float valve 7 gradually increases, allowing more steam to pass through to adapt to the demand of gas-liquid mixing. When the feed quantity is too large, the operator can control the steam quantity to further increase through the control system of the float valve tower, so that the impact on the moving plate 4 is greater than the elastic force of the reset spring 12, and the moving plate 4 moves upward under the push of the steam. The upward movement of the moving plate 4 drives the second float valve 8 mounted thereon to move upward and open, and the air quantity of the second through hole 6 increases, thereby allowing more steam to pass through the second through hole 6 to make more sufficient contact and mass transfer with the liquid, so as to adapt to the larger flow of liquid. When the steam quantity decreases or the feed flow returns to normal, the reset spring 12 pushes the moving plate 4 to move downward, the second float valve 8 is closed or the opening is reduced, and at the same time, the first float valve 7 also automatically adjusts the opening according to the change of the steam quantity, the whole tray returns to the normal working state, realizes the self-adaptive regulation of the feed flow fluctuation, and ensures that the tower equipment can run efficiently and stably under various working conditions.

[0027] In summary:

[0028] 1. When steam rises, the steam enters the sleeve 11 inside the first through hole 5 of the moving plate 4 after passing through the first through hole 5 of the moving plate 4, and impacts the first float valve 7 inside the sleeve 11, so that the first float valve 7 is opened upward. The opening degree of the first float valve 7 increases with the increase of the steam amount, thereby allowing more steam to pass through the first through hole 5 and mix with the liquid at the top of the tray body 1. When the feed amount is too large, the air amount is further increased, so that the impact of the steam on the moving plate 4 is greater than the elastic force of the reset spring 12, so that the moving plate 4 is impacted and moves upward, and the second float valve 8 installed on the moving plate 4 is driven to move upward and open by the upward movement of the moving plate 4. The opening and closing degree of the second float valve 8 increases with the upward movement of the moving plate 4, and the upward movement degree of the moving plate 4 increases with the increase of the air amount, thereby allowing more steam to pass through the second through hole 6, and adapting to larger flow of liquid by increasing the air amount of the second through hole 6, thereby solving the problem that the air and liquid passing amounts are difficult to change flexibly when the float valve tray is faced with the feed flow fluctuation.
