Description

Technical Field

[0001] The invention relates to the technical field of gas-liquid distributors, and in particular to a gas-liquid distributor with adjustable distribution angle. Background Art

[0002] A gas-liquid distributor is a device used to distribute gas and liquid to various locations in a device or system to achieve uniform and precise gas-liquid distribution. Among gas-liquid distributors, the pipeline distributor is the most common one, which guides gas and liquid to different outlets through pipelines and pipe joints, and achieves uniform distribution of gas and liquid through pipeline layout and fluid flow control.

[0003] Packed tower technology is a separation technology widely used in oil refining, petrochemical and coal chemical industries. Gas or liquid distributors are important internal components of packed towers. In industrial applications, there is also a need to evenly distribute liquid and gas at the same time, so there is a need for facilities to evenly distribute gas and liquid at the same time.

[0004] The existing gas-liquid distributor adopts an intermittent drive component, so that the main body of the gas-liquid distributor can rotate intermittently when distributing liquid, so that the liquid can be more comprehensively distributed in the packing layer in the distillation tower. In this way, an additional drive mechanism is required to drive the gas-liquid distributor to rotate, and the existing fan in the packing tower cannot be directly used, which increases the cost. In addition, the intermittent rotation makes the effect of uniform distribution of gas and liquid poor, which is not conducive to improving the uniformity of gas-liquid distribution.

[0005] The existing pipeline gas-liquid distributor uses two sets of motors to control the movement of the dispensing pipe, thereby controlling the front and back and left and right angles of multiple discharge heads on the dispensing pipe to achieve angle distribution adjustment of the discharge heads. In this method, two sets of motors are required to control the front and back and left and right angles of the discharge heads, which increases the cost, and the angle control effect of the discharge heads is poor. It is impossible to control the angle of each discharge head according to the needs of temperature control, which reduces the regulation and control of the local temperature above the filler and reduces the uniform distribution effect of the liquid.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] The present invention arranges a gas distributor. When the fan in the top air outlet of the counterflow cooling tower is working, the hot and humid air from the outside quickly enters the air distribution pipe through the air inlet pipe, the vertical pipe and the spiral tube, and is sprayed to the bottom of the filler through the air jet port on the air distribution pipe. After the air flow flows out of the air distribution pipe, it drives the air distribution pipe to rotate, causing the spiral tube to rotate. The air is evenly distributed at the bottom of the filler through the rotation, thereby improving the gas distribution effect.

[0022] The present invention provides a sealing component, and the water storage pipe is filled with water to form a liquid seal effect on the vertical pipe and the spiral pipe, which effectively prevents air from leaking from the rotating gap between the vertical pipe and the spiral pipe, and improves the gas distribution effect. When the humid hot air passes through the gas distribution pipe, the temperature is reduced and moisture is precipitated. The moisture flows back into the spiral pipe through the gas distribution pipe, enters the annular flow channel under the obstruction of the boss, and enters the water storage pipe, and finally overflows and flows into the bottom of the counterflow cooling tower, which effectively prevents water from flowing into the vertical pipe and ensures the gas outlet effect of the gas distributor.

[0023] The present invention sets a liquid distributor, and the controller receives the signal of the temperature sensor to control the operation of the air supply component and the inflation component. When the temperature is high, the airbags in the corresponding direction are inflated and expanded, and when the temperature is low, the airbags in the corresponding direction are evacuated and contracted. Under the changes of inflation or evacuation of the airbags around, the metal hose is pushed to deflect toward the low temperature direction, so that the nozzle sprays hot water in the direction where the hot water is too little in the filler. The hot water in the filler is evenly distributed by continuously adjusting the distribution angle of the nozzle.

[0024] The present invention provides a coil, which generates an induced magnetic field after being energized, so that the interior of the counterflow cooling tower is in the magnetic field, and the condensed water at the bottom of the filler is magnetized under the action of the magnetic field, so that the condensed water falls into the bottom of the counterflow cooling tower under the influence of the magnetic field and gravity; at the same time, when hot water enters the pipeline through the water inlet pipe, the hot water is magnetized into magnetized water in the magnetic field, which reduces the generation of scale in the liquid distributor, effectively prevents the clogging of the nozzle, and improves the surface tension and evaporation rate of the hot water, so that the hot water can quickly exchange heat with the cold air after being sprayed into the filler from the nozzle and evaporate more to the air, thereby improving the cooling efficiency and reducing the maintenance frequency.

DETAILED DESCRIPTION

[0034] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0036] The gas distributor 4 includes an air inlet pipe 41, one end of which is connected to the air inlet, and the other end extends into the counterflow cooling tower 1 and is connected to a vertical pipe 43. The top of the vertical pipe 43 is rotatably connected and is connected to a spiral tube 45. The spiral tube 45 is connected to a plurality of air distribution pipes 46 on the periphery. The air distribution pipe 46 is provided with a plurality of jet ports 461, and the jet ports 461 are axially inclined upward to point to the bottom of the filler 2.

[0037] The water outlet pipe 14 has its top end connected to the bottom of the counterflow cooling tower 1 and a valve installed on the water outlet pipe 14 .

[0038] The air inlet pipe 41 is trumpet-shaped, and the end with a smaller diameter is connected to the vertical pipe 43 , and the end with a larger diameter is connected to the air inlet. The diameter of the air distribution pipe 46 is smaller than the diameter of the vertical pipe 43 .

[0039] A baffle 42 is fixedly connected to one end of the air inlet pipe 41 that is connected to the air inlet, and the baffle 42 is a porous structure.

[0040] A stainless steel bearing 47 is installed between the outer circumference of the vertical pipe 43 and the inner circumference of the spiral pipe 45 . The vertical pipe 43 and the spiral pipe 45 are rotatably connected via the stainless steel bearing 47 .

[0041] A sealing assembly is connected between the riser 43 and the coil 45, and the sealing assembly includes a water storage pipe 44, and a plurality of air distribution pipes 46 are arranged obliquely upward away from one end of the coil 45. A boss 431 is connected to the top of the riser 43, and the top of the boss 431 is connected to the inside of the coil 45. The water storage pipe 44 is fixedly connected to the outer peripheral side of the riser 43, and the inner peripheral side of the bottom end of the coil 45 and the outer peripheral side of the riser 43 form an annular flow channel, wherein a stainless steel bearing 47 is located in the annular flow channel, and the bottom of the annular flow channel is connected to the inside of the water storage pipe 44, and the top of the water storage pipe 44 is higher than the bottom end of the annular flow channel, and the water storage pipe 44 is filled with water.

[0042] The law of conservation of momentum states that in a closed system, the total momentum of the system remains constant. This means that when one object accelerates, another object must decelerate to keep the total momentum of the system constant. In this scenario, when the air flows out of the positive pressure pipe, i.e., the air distribution pipe 46, into the negative pressure environment, i.e., the counterflow cooling tower 1, it will accelerate. In order to maintain the conservation of momentum, the pipe must move in the opposite direction, thereby generating a recoil force.

[0043] Reference Figure 1 , Figure 2 , Figure 6-Figure 8 , liquid distributor 3, the liquid distributor 3 includes a water inlet pipe 31, one end of the water inlet pipe 31 is connected to the output end of the external hot water source, and the other end extends into the counterflow cooling tower 1 and is connected to a pipeline, a plurality of metal hoses 341 are connected to the bottom of the pipeline, a nozzle 34 is connected to the bottom of the metal hose 341, the output end of the nozzle 34 points to the top of the filler 2, and an angle adjustment component is connected to the bottom of the metal hose 341, and the angle adjustment component is used to sense the temperature around the metal hose 341 and control the angle of the metal hose 341.

[0044] The pipeline includes a main water pipe 32, the middle part of which is connected to the water inlet pipe 31, and multiple branch pipes 33 are connected on both sides. The multiple branch pipes 33 are fitted with the inner wall gap of the counterflow cooling tower 1 at one end away from the main water pipe 32, and multiple metal hoses 341 are evenly distributed and connected at the bottom of the branch pipes 33.

[0045] The angle adjustment assembly includes a bracket 345, which is fixedly connected to the water distribution pipe 33. An adjustment groove is opened through the bottom of the bracket 345, and the inner side of the adjustment groove is gap-matched with the outer side of the bottom end of the metal hose 341. A plurality of temperature sensors 346 are installed around the bracket 345, and a plurality of air bags 347 are fixedly connected to the inner side of the adjustment groove. The plurality of air bags 347 correspond one-to-one to the plurality of temperature sensors 346. The sides of the plurality of air bags 347 away from the inner wall of the adjustment groove are all against the outer side of the metal hose 341. The plurality of air bags 347 are all connected with an inflatable component, which is connected to the bracket 345. The input ends of the plurality of inflatable components are connected with the same air supply component, which is connected to the counterflow cooling tower 1. A controller is installed on the counterflow cooling tower 1. The temperature sensor 346, the inflatable component and the air supply component are all electrically connected to the controller. The controller is used to receive signals from the plurality of temperature sensors 346 and control the working states of the air supply component and the plurality of inflatable components.

[0046] The inflatable component includes an air pipe 343, one end of which is connected to the air supply component, and the other end is connected to a multi-way reversing valve 342. The multi-way reversing valve 342 is installed on the top of the bracket 345. Multiple working ends of the multi-way reversing valve 342 are all connected to an air pipe 344. Multiple air pipes 344 are connected to multiple air bags 347 one by one away from one end of the multi-way reversing valve 342. The multi-way reversing valve 342 is electrically connected to the controller.

[0047] The air supply component includes an air extraction and inflation dual-purpose pump 13, which is installed on the outside of the counterflow cooling tower 1. The working end of the air extraction and inflation dual-purpose pump 13 is connected to an air pipe 131. The air pipe 131 is sealed and penetrates into the counterflow cooling tower 1 away from one end of the air extraction and inflation dual-purpose pump 13, and is connected to multiple air pipes 343. The air extraction and inflation dual-purpose pump 13 is electrically connected to the controller.

[0048] A coil 12 is wound around the outer circumference of the counterflow cooling tower 1 , and the coil 12 is connected to an external power supply wire.

[0049] When the present invention works in a humid and hot environment, the external power supply energizes the coil 12, and the coil 12 generates an induced magnetic field after being energized, so that the interior of the counterflow cooling tower 1 is in the magnetic field;

[0050] The fan in the air outlet 11 at the top of the counterflow cooling tower 1 works to discharge the hot air in the counterflow cooling tower 1 to the outside, so that negative pressure is generated in the counterflow cooling tower 1. Under the action of the negative pressure, the outside air enters the gas distributor 4 from the air inlet, and the baffle 42 with a porous structure blocks the debris in the air to prevent the debris from entering the gas distributor 4;

[0051] When the outside air enters the air intake pipe 41 through the air inlet, the trumpet-shaped air intake pipe 41 gradually increases the flow rate of the air passing through it. The air with increased flow rate enters the vertical pipe 43 through the air intake pipe 41, and then enters the spiral tube 45 through the vertical pipe 43. Each air distribution pipe 46 is slightly inclined upward from the center of the spiral tube 45 to the outside. Since the gas flow rate is inversely proportional to the temperature, the air that quickly enters the air distribution pipe 46 is cooled and moisture is precipitated. The precipitated moisture gradually condenses into water droplets in the air distribution pipe 46. The condensed water flows along the slope of the air distribution pipe 46 toward the spiral tube 45, and the condensed water that flows out is blocked by the inclined surface of the boss 431. It falls into the annular flow channel, flows through the stainless steel bearing 47 and enters the water storage pipe 44. The top of the water storage pipe 44 is higher than the bottom of the spiral 45 and slightly lower than the top of the boss 431 and is filled with water in advance. The condensed water in the gas distribution pipe 46 flows into the water storage pipe 44, and the water in the water storage pipe 44 forms a liquid seal effect on the vertical pipe 43 and the spiral 45, so that the air in the gas distributor 4 cannot enter the counterflow cooling tower 1 through the stainless steel bearing 47, ensuring the normal operation of the gas distributor 4. When too much water enters, the water will automatically overflow the water storage pipe 44 and fall to the bottom of the counterflow cooling tower 1, effectively preventing water from flowing into the vertical pipe 43;

[0052] The air in the air distribution pipe 46 is finally throttled and continuously ejected at high speed from the suddenly narrowed jet port 461, enters the bottom of the packing 2 and greatly reduces the temperature. After being ejected through the air distribution pipe 46, the high-speed ejected air gives the air distribution pipe 46 a force in the opposite direction of the air ejection, causing the spiral tube 45 to rotate, and the air is evenly distributed at the bottom of the packing 2 through the rotation;

[0053] As the air is ejected at high speed and the temperature is greatly reduced, some moisture and some condensed water will be precipitated from the air. Under the action of the magnetic field, the water will be magnetized and fall to the bottom of the counterflow cooling tower 1 under the influence of the magnetic field and gravity.

[0054] The air distribution pipe 46 rotates while jetting and continuously hits the cooling water falling from the packing 2 to form turbulence. The ejected air forms bubbles in the water and enters the packing 2 upward to exchange heat with the hot water. In the turbulence, the bubbles are continuously broken into countless small bubbles and enter the packing 2, thereby increasing the heat exchange efficiency in the packing 2. The air is dry and low in temperature, further improving the cooling effect.

[0055] The output end of the external hot water source outputs hot water into the water inlet pipe 31. The hot water enters the liquid distributor 3 through the water inlet pipe 31 and is magnetized into magnetized water in the magnetic field, which reduces the generation of scale in the liquid distributor 3, reduces the blockage of the nozzle 34, and improves the surface tension and evaporation rate of the hot water, so that the hot water can quickly exchange heat with the cold air after being sprayed into the filler 2 from the nozzle 34 and evaporate more into the air, thereby improving the cooling efficiency and reducing the maintenance frequency;

[0056] In the initial state, the pressures of the air bags 347 are the same and they respectively press against the metal hose 341. Under the force balance, the nozzle 34 sprays hot water vertically toward the filler 2.

[0057] When the dual-purpose pump 13 for pumping and exhausting air is working, its working end is used to inflate or exhaust air through the air pipe 131;

[0058] When the temperature sensor 346 in a certain direction of the metal hose 341 detects that the hot air temperature is too high, it is determined that there is too much hot water in the filler 2 below the temperature sensor 346 and a feedback signal is given. The controller receives the signal, controls the dual-purpose pump 13 for air extraction and inflation to work, inflates air to the outside through the air pipe 1 131, and controls the multi-way reversing valve 342 to work, connects the corresponding air pipe 2 343 and air pipe 3 344, and inflates the airbag 347 in the same direction; when the temperature sensor 346 in a certain direction of the metal hose 341 detects that the hot air temperature is too low, the dual-purpose pump 13 for air extraction is controlled to work for air extraction, so that the airbag 347 in the corresponding direction is deflated;

[0059] As the air bags 347 around the packing 34 are inflated or contracted, the metal hose 341 is pushed to deflect in the opposite direction of the inflated air bags 347 and in the same direction of the contracted air bags 347, thereby changing the direction of the nozzle 34, so that the nozzle 34 sprays hot water in the direction where there is too little hot water in the filler 2. By continuously adjusting the distribution angle of the nozzle 34, the hot water in the filler 2 is evenly distributed, and evaporates and exchanges heat with the evenly distributed dry low-temperature air rising from the bottom, thereby increasing the cooling rate, saving energy and reducing water waste.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
