Description

Technical Field

[0001] This utility model relates to the field of fluid distributor technology, and in particular to a novel intelligent fluid distributor. Background Technology

[0002] According to a liquid distributor for a desulfurization absorption tower disclosed in Chinese Publication No. CN103920372A, the feed pipe is connected to the liquid guide pipe, and a distribution pipe is connected to the lower part of the liquid guide pipe. Baffles are provided on both sides of the distribution pipe, and the baffles are located in a first-stage tank. A second-stage tank is located below the first-stage tank, with multiple second-stage tanks arranged in a near-circular interval. The second-stage tanks are connected by connecting pipes. Distribution holes are provided in the first-stage tank section below the baffles and above the second-stage tank, and in the lower part of the second-stage tank. This liquid distributor can balance and distribute uneven liquids, exhibiting good liquid distribution effect, high efficiency, and simple structure. It is suitable for application as a liquid distributor in the chemical industry.

[0003] In chemical production processes, the fluid flow rate of the aforementioned and existing distributors is not constant. Significant fluctuations occur during startup, shutdown, and load adjustments. Distributors with fixed orifice sizes cannot adjust to these flow rate changes. When the flow rate is too low, the fluid cannot evenly cover the entire distribution area, resulting in insufficient distribution in some areas and affecting mass transfer and reaction efficiency within the chemical tower. Conversely, when the flow rate is too high, the excessive flow velocity causes a large pressure drop within the distributor, increasing energy consumption and potentially damaging the distributor structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot adjust the orifice size of the distributor surface based on flow rate, and to propose a novel intelligent fluid distributor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel intelligent fluid distributor, comprising a primary tank, a secondary tank arranged horizontally at the bottom of the primary tank, a distribution tank inside the primary tank, a first water pipe at the top of the distribution tank, a second water pipe at the top of the secondary tank, a third water pipe arranged horizontally at the bottom of the second water pipe, two pistons inside each of the third water pipes, and a return spring sleeved on the outside of each piston, two movable plates at the bottom of the secondary tank, two guide grooves on the bottom surface of the secondary tank, a first through hole arranged in an array on the surface of each movable plate, a second through hole arranged on one side of each first through hole on the surface of the movable plate, and a first through hole arranged in an array on the bottom surface of both the secondary tank and the primary tank, and a temperature sensor arranged on one side of the primary tank.

[0006] Preferably, the primary groove is installed on the top surface of the secondary groove, and the primary groove is installed in the middle position of the top surface of the secondary groove. The primary groove and the secondary groove are bolted together. The temperature sensor is installed on the side of the primary groove and is bolted together with the primary groove.

[0007] Preferably, the distribution groove is installed inside the primary groove and in the middle position of the primary groove, and the distribution groove is welded to the primary groove.

[0008] Preferably, the first water pipe is installed on the top surface of the primary tank and is bolted to the primary tank; the second water pipe is installed on the top surface of the secondary tank and is snapped into the secondary tank; and the vertical central axes of the first water pipe, the second water pipe, the primary tank, and the distribution tank are aligned.

[0009] Preferably, the third water pipes arranged in the horizontal array at the bottom of the second water pipes correspond one-to-one with the positions of the secondary grooves arranged in the horizontal array at the bottom of the second water pipes, and one end of each third water pipe penetrates the bottom surface of the secondary groove and is threadedly connected to the second water pipe.

[0010] Preferably, the two movable plates at the bottom of the secondary tank are mirror images of each other with the second water pipe as the center, and both ends of the movable plates are installed in the two guide grooves on the bottom surface of the secondary tank.

[0011] Preferably, the third water pipe is T-shaped, and the two pistons inside the third water pipe are mirror images of the second water pipe. One end of each piston extends through the third water pipe, and the end of each piston extending through the third water pipe is bolted to the movable plates on both sides of the third water pipe. The two return springs sleeved on the outside of the two pistons are installed inside the third water pipe.

[0012] Beneficial effects

[0013] In this invention, when the orifice size needs to be changed, the water pump connected to the second water pipe is turned on through the control system of the chemical tower. The water pump delivers liquid into the interior of the second water pipe, and then into the interior of the third water pipe. When the water pressure is further increased, the high-pressure water flow squeezes two pistons inside the third water pipe, causing the two pistons to extend and retract outwards. The pistons push the moving plate at the bottom of the secondary tank, causing the moving plate to move to both sides. This moves the second through hole on the surface of the moving plate to the position of the second through hole on the bottom surface of the secondary tank and aligns it with the second through hole, thereby increasing the size of the through hole in the secondary tank. This solves the problem of not being able to change the orifice size of the distributor surface according to the flow rate. Attached Figure Description

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0025] Reference Figure 1-6A novel intelligent fluid distributor includes a primary tank 1, a secondary tank 2 horizontally arranged at the bottom of the primary tank 1, a distribution tank 3 inside the primary tank 1, a first water pipe 4 at the top of the distribution tank 3, a second water pipe 5 at the top of the secondary tank 2, a third water pipe 6 horizontally arranged at the bottom of the second water pipe 5, two pistons 7 inside each of the third water pipes 6, and a return spring 8 sleeved on the outside of each piston 7. Two movable plates 9 are located at the bottom of the secondary tank 2, and two guide grooves 12 are located on the bottom surface of the secondary tank 2. The surfaces of the movable plates 9 are arranged with a first... A second through hole 11 is provided on one side of the first through hole 10 on the surface of the movable plate 9, and the bottom surfaces of the secondary groove 2 and the primary groove 1 are arrayed with first through holes 10. A temperature sensor 13 is provided on one side of the primary groove 1. The primary groove 1 is installed on the top surface of the secondary groove 2, and the primary groove 1 is installed in the middle position of the top surface of the secondary groove 2. The primary groove 1 and the secondary groove 2 are bolted together. The temperature sensor 13 is installed on the side of the primary groove 1, and the temperature sensor 13 is bolted together with the primary groove 1. The distribution groove 3 is installed inside the primary groove 1, and the distribution groove 3 is installed with... At the middle position of the primary trough 1, the distribution trough 3 is welded to the primary trough 1. The first water pipe 4 is installed on the top surface of the primary trough 1 and is bolted to the primary trough 1. The second water pipe 5 is installed on the top surface of the secondary trough 2 and is snapped into the secondary trough 2. The vertical central axes of the first water pipe 4, the second water pipe 5, the primary trough 1, and the distribution trough 3 are aligned. The third water pipe 6, which is horizontally arrayed at the bottom of the second water pipe 5, corresponds one-to-one with the positions of the secondary troughs 2 horizontally arrayed at the bottom of the second water pipe 5. One end of each third water pipe 6 penetrates the bottom surface of the secondary trough 2 and connects to the distribution trough 1. The second water pipe 5 is threaded. The two movable plates 9 at the bottom of the secondary tank 2 are mirror images of the second water pipe 5. Both ends of the movable plates 9 are installed in the two guide grooves 12 on the bottom surface of the secondary tank 2. The third water pipe 6 is T-shaped. The two pistons 7 inside the third water pipe 6 are mirror images of the second water pipe 5. One end of each piston 7 extends through the third water pipe 6. The ends of the pistons 7 extending through the third water pipe 6 are bolted to the movable plates 9 on both sides of the third water pipe 6. The two return springs 8 sleeved on the outside of the two pistons 7 are installed inside the third water pipe 6.

[0026] The primary tank 1 serves as the upper liquid receiving and initial distribution structure. The first through-hole 10, arranged horizontally inside, guides the liquid downwards to the secondary tank 2. Its position and number correspond to those of the secondary tank 2, ensuring uniform liquid distribution throughout the secondary tanks 2. The secondary tank 2 receives the liquid flowing down from the primary tank 1 and further distributes it downwards. A movable plate 9 is located at the bottom to control the size of the liquid outflow orifice. A guide groove 12 on the bottom surface guides the movement of the movable plate 9. The distribution tank 3 is located inside the primary tank 1, receiving the liquid flowing in from the first water pipe 4. When the tank is full, the liquid overflows to both sides and flows into the primary tank 1, serving as a buffer and initial uniform liquid distribution. The first water pipe 4 is connected to a water pump connected to the chemical tower control system, receiving the delivered liquid. Multiple through-holes are evenly spaced on the bottom surface, allowing the liquid to flow into the distribution tank 3. The second water pipe 5 is installed at the top of the secondary tank 2, and the water pump delivers the liquid to its interior, where it flows into the third water pipe 6. The third water pipe 6 is T-shaped, with two pistons 7 at its bottom. When high-pressure water flows into the second water pipe 5, it compresses the piston 7, causing it to extend and retract outwards. The piston 7, inside the third water pipe 6, is compressed by the high-pressure water flow, with one end extending through the third water pipe 6 and bolted to the movable plate 9. Its extension and retraction pushes the movable plate 9, thereby changing the through-hole state of the secondary tank 2. A return spring 8 is fitted around the piston 7 and installed inside the third water pipe 6. When the water pressure decreases, the return spring 8 resets the piston 7, and the movable plate 9 returns to its initial position, restoring the initial through-hole state of the secondary tank 2. The movable plate 9 is located at the bottom of the secondary tank 2, and its surface is arrayed with a first through-hole 10 and a second through-hole 11. Normally, the second through-hole 11 is aligned with the first through-hole 10 on the bottom surface of the secondary tank 2 to control the liquid flow rate; under the push of the piston 7, it can move to both sides, changing the alignment of the through-holes and adjusting the flow rate. A guide groove 12 is formed on the bottom surface of the secondary tank 2, providing directional guidance for the movement of the movable plate 9 and ensuring its smooth movement. Temperature sensor 13 is installed on the side of primary tank 1 to monitor the liquid temperature in primary tank 1 in real time and feeds the temperature data back to the chemical tower control system, providing a basis for adjusting the system's operating parameters. When the temperature inside the chemical tower changes, the resistance value of the thermistor in temperature sensor 13 changes accordingly. The internal circuit of temperature sensor 13 converts the change in resistance value into an electrical signal, which is then converted into a voltage change through a Wheatstone bridge circuit. This voltage signal is amplified, filtered, and then transmitted to the intelligent control system. The control system converts the received electrical signal into the actual temperature value according to the preset temperature-resistance value correspondence. If the detected temperature exceeds or falls below the set threshold range, the control system will issue corresponding instructions, such as adjusting the operating parameters of the fluid distributor, to ensure that the fluid is distributed at a suitable temperature and maintain the stability of the reaction or operation within the chemical tower. Temperature sensor 13 is existing technology and is not an innovation of this technology.

[0027] It should be noted that the position and number of the first through holes 10 in the internal horizontal array of the first-level tank 1 correspond one-to-one with the number and position of the second-level tanks 2 set in the bottom horizontal array of the first-level tank 1, so that when the liquid flows down into the second-level tanks 2 set in the array through the first through holes 10 on the bottom surface of the first-level tank 1, the number of second-level tanks 2 can be determined according to the specific implementation situation. Specific Implementation Example 2:

[0029] Reference Figure 1-6 A novel intelligent fluid distributor, further based on the basic structure in Specific Embodiment 1, performs normal flow distribution as follows: The water pump connected to the first water pipe 4 is activated by the chemical tower control system. Liquid enters the first water pipe 4 and flows into the distribution tank 3 through its bottom through-hole. When the distribution tank 3 is full, the liquid overflows into the primary tank 1, and then flows into the secondary tank 2 through the first through-hole 10 on the bottom surface of the primary tank 1. Since the first through-hole 10 on the bottom surface of the secondary tank 2 is blocked by the moving plate 9, and the second through-hole 11 of the moving plate 9 is usually aligned with the first through-hole 10 on the bottom surface of the secondary tank 2, the flow rate flowing downwards in the secondary tank 2 is reduced due to the smaller diameter of the second through-hole 11 compared to the first through-hole 10, thus completing the liquid distribution under normal flow conditions.

[0030] Orifice Diameter and Flow Rate Adjustment: When the orifice size needs to be changed, the chemical tower control system starts the water pump connected to the second water pipe 5, and liquid flows into the second water pipe 5 and the third water pipe 6. The water pressure continues to increase, and the high-pressure water flow squeezes the piston 7 inside the third water pipe 6. The piston 7 pushes the bottom moving plate 9 of the secondary tank 2 to move to both sides, causing the second through hole 11 on the surface of the moving plate 9 to shift out of position from the first through hole 10 on the bottom surface of the secondary tank 2, aligning the first through hole 10 with it. This enlarges the through hole of the secondary tank 2, thereby increasing the liquid flow rate and realizing the function of changing the orifice size of the distributor surface according to flow requirements. Simultaneously, the temperature sensor 13 monitors the internal temperature of the chemical tower in real time, providing temperature data support for the overall operation control of the chemical tower.

[0031] In summary:

[0032] 1. When the orifice size needs to be changed, the water pump connected to the second water pipe 5 is turned on through the control system of the chemical tower, so that the water pump delivers the liquid into the interior of the second water pipe 5 and flows into the interior of the third water pipe 6 through the second water pipe 5. When the water pressure is further increased, the high-pressure water flow will squeeze the two pistons 7 inside the third water pipe 6, causing the two pistons 7 to extend and retract outwards. The pistons 7 push the moving plate 9 at the bottom of the secondary tank 2, causing the moving plate 9 to move to both sides, so that the second through hole 11 on the surface of the moving plate 9 moves to the position of the second through hole 11 on the bottom surface of the secondary tank 2 and aligns with it, thereby increasing the through hole of the secondary tank 2. This solves the disadvantage that the orifice size of the distributor surface cannot be changed according to the flow rate.
