Description

Technical Field

[0001] This invention belongs to the technical field of gas-liquid reaction devices, specifically a method and device for improving the efficiency of gas-liquid reactions. Background Technology

[0002] Venturi wet scrubbing towers are commonly used in petroleum refining and chemical industries. These include the VSS (Venturi Scrubbing System) technology imported from Norton Engineering in the United States, and the WGS (Wet Gas Scrubber) technology from ExxonMobil and Hamon. This process uses an alkaline solution as the scrubbing agent (scrubbing liquid). The flue gas first enters a Venturi tube equipped with scrubbing liquid nozzles. The negative pressure created by the scrubbing liquid being sprayed into the Venturi throat draws the flue gas into the scrubbing tower. The scrubbing agent enters the Venturi tube in the same direction as the flue gas, and the absorption process occurs in the turbulent section of the Venturi tube.

[0003] The alkaline detergent sodium hydroxide solution forms a thin film on the wall of the narrowing section, and is then broken into droplets at the entrance of the throat section. Due to the relative velocity difference, inertial collisions occur between the gas and the droplets, and the soot particles are captured and removed in the throat section. SOx is absorbed in the throat section and the widening section, forming sodium sulfite and sodium sulfate.

[0004] The gas-liquid mixture enters the scrubbing tower and passes through the mass transfer element (i.e., the porous toothed flue gas flow equalization and efficiency improvement device) to generate a chaotic gas-liquid state, improve the utilization efficiency of the scrubbing liquid, promote the mass transfer efficiency between gas and liquid, enhance the sufficiency and uniformity of gas-liquid contact, and help the gas and liquid phases react better. The gas and liquid rotate in the scrubber to separate the clean gas from the dirty detergent liquid. The de-entraining device in the scrubbing tower is characterized by high efficiency, low clogging, and low pressure drop. It removes the detergent liquid entrained in the gas and returns it to the bottom of the tower through the external circulation line. The detergent solution in the external circulation downcomer also agitates the slurry at the bottom of the tower, so that the catalyst dust in the slurry at the bottom of the tower is in a uniform suspended state. The clean gas is discharged into the atmosphere through the chimney at the top of the separator. In the prior art, when gas passes through a mass transfer element, some impurities in the flue gas tend to adhere to the bottom surface of the mass transfer element. If the deposition time is too long, the impurities will block the star-shaped holes on the mass transfer element, resulting in a reduction in the flow rate of flue gas through the star-shaped holes, which in turn affects the washing and purification efficiency of the flue gas. Although the surface of the mass transfer element is rinsed by spraying cleaning liquid through the washing nozzle above, the bottom of the mass transfer element cannot be directly rinsed and the top impurities have a strong adhesion force and cannot be rinsed clean, which affects the cleaning effect of the mass transfer element. To address this issue, we propose a gas-liquid reaction efficiency improvement method and device. Summary of the Invention

[0005] The purpose of this invention is to provide a method and apparatus for improving the efficiency of gas-liquid reaction, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for improving the efficiency of gas-liquid reactions, specifically comprising the following steps: S1. External flue gas enters the scrubbing tower through a venturi tube and is flow-equalized and efficiency-enhanced through mass transfer components. S2. When flue gas impurities adhere to the bottom surface of the mass transfer component, the upper motor is turned on to drive the rotating column to rotate, which in turn drives multiple sets of strip brushes to rotate and clean the attached impurities. S3. Turn on the motor to drive the bidirectional lead screw to rotate, which drives the two sets of nut seats to move in opposite directions, thereby driving multiple sets of strip brushes to move in opposite directions, so as to adjust the contact pressure of the strip brushes on the mass transfer component. S4. After passing through the mass transfer element, the flue gas enters the area above the mass transfer element. The surface of the mass transfer element is rinsed by the cleaning fluid sprayed through the washing nozzle. Then, the gas mist enters the demister to remove the liquid droplets in the mist state. Subsequently, the clean gas is discharged from the top of the scrubbing tower.

[0007] Preferably, the washing tower in step S1 includes a mass transfer element installed inside the washing tower. The mass transfer element has multiple sets of star-shaped holes inside. The mass transfer element is equipped with a cleaning mechanism, which includes: A rotating column is rotatably disposed inside the mass transfer element and multiple sets of strip brushes are located outside the rotating column. Two sets of limiting strips are fixedly disposed on the outer wall of the rotating column. Two sets of mounting rings are slidably disposed outside the rotating column and the limiting strips. Multiple sets of extending bristles are fixedly disposed at the top and bottom of the mass transfer element.

[0008] Preferably, a sliding ring is sleeved on the outside of the rotating column, and a fixed bearing is fixedly installed on the outside of the sliding ring.

[0009] Preferably, an upper bevel gear two is fixedly installed on the outer top of the rotating column, and an upper bevel gear one meshes with the outer side of the upper bevel gear two. An upper rotating rod is rotatably installed inside the washing tower, and an upper motor is fixedly installed outside the washing tower. A conical box is installed outside the upper bevel gear two and the upper bevel gear one, and a central rotating rod is fixedly installed between the conical box and the inner wall of the mass transfer element.

[0010] Preferably, the outside of the rotating column is provided with an adjusting member for adjusting the spacing between multiple sets of strip brushes, the adjusting member comprising: A bidirectional lead screw is rotatably mounted on the outside of the rotating column. Two sets of nut seats are provided on the outside of the bidirectional lead screw to drive the strip brush to move.

[0011] Preferably, two sets of connecting bearings are fixedly installed on the outer wall of the rotating column, and the bidirectional lead screw is rotatably disposed inside the connecting bearings.

[0012] Preferably, an outer bearing is also fitted and fixed to the outside of the rotating column, and a lower bevel gear II is fixedly installed on the outer wall of the outer bearing. A lower bevel gear I meshes with the outer wall of the lower bevel gear II. A lower rotating rod is rotatably installed inside the washing tower, and a lower motor is fixedly installed on the outer wall of the washing tower.

[0013] Preferably, the washing tower is provided with two sets of limiting members, each including a hydraulic rod fixed on the washing tower, and a limiting rod fixedly provided at the working end of the hydraulic rod.

[0014] Preferably, the inner wall of the washing tower is fixedly provided with two sets of spray pipes, the bottom of the spray pipes is fixedly provided with multiple sets of washing nozzles, the inner wall of the washing tower is fixedly provided with multiple sets of support plates, the support plates are fixedly provided with demisters, the top inner wall of the washing tower is fixedly provided with two sets of connecting pipes, the bottom of the connecting pipes is fixedly provided with multiple sets of rinsing nozzles.

[0015] Preferably, a rinsing water tank is provided on one side of the washing tower, and a left pipeline is provided on the rinsing water tank, while a right pipeline is provided on the other side of the washing tower.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention has a cleaning mechanism in which the strip brush can rotate with the rotating column and its end can extend into the star-shaped hole to directly clean the impurities in the hole and the bottom and top surfaces of the mass transfer component. At the same time, when the strip brush comes into contact with the extended bristles of the mass transfer component, they clean each other and can automatically remove the soft bristles and impurities attached to the strip brush and the extended bristles, reducing the frequency and difficulty of cleaning and indirectly improving the cleaning effect on the mass transfer component. At the same time, with the flushing action of the washing nozzle, the cleaning effect on the mass transfer component can be further increased, ensuring the star-shaped hole is unobstructed and improving the smoothness of the flue gas passing through the mass transfer component.

[0017] (2) The present invention uses a designed adjustment component to drive two sets of nut seats and mounting rings to move in opposite directions or in opposite directions by a bidirectional screw, thereby adjusting the contact pressure between the brush and the mass transfer component. By adjusting the contact pressure between the brush and the mass transfer component, the wear of the soft bristles on the brush caused by excessive squeezing can be reduced. At the same time, the problem of frequent cleaning due to impurities caused by insufficient pressure is avoided, which reduces the replacement frequency of the brush and the cost of manual maintenance, and improves the economy and continuous operation capability of the device.

[0018] (3) The present invention uses a designed limiting component to drive the limiting rod to contact the upper or lower rotating rod and limit its rotation through a hydraulic rod. In the non-cleaning state, limiting the upper rotating rod can prevent the upper motor from starting unexpectedly and causing the rotating column and strip brush to rotate erroneously, thus preventing unnecessary wear of the strip brush or additional friction on the mass transfer components. In the non-adjustment state, limiting the lower rotating rod can prevent the lower motor from starting unexpectedly and causing the bidirectional lead screw to rotate erroneously, thus preventing abnormal changes in the strip brush spacing from affecting the cleaning effect. This avoids the misoperation of key components from the source and ensures the stable operation of the device. Attached Figure Description

Detailed Implementation

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figures 1-5 This invention provides a technical solution: a method for improving the efficiency of gas-liquid reactions, specifically including the following steps: S1. External flue gas enters the scrubbing tower 106 through the venturi tube 101, and is uniformly flowed and efficient through the mass transfer element 109. After passing through the mass transfer element 109, the flue gas becomes a mist. S2. When flue gas impurities adhere to the bottom surface of the mass transfer component 109, the upper motor 208 is turned on to drive the rotating column 201 to rotate, which in turn drives multiple sets of strip brushes 202 to rotate and clean the attached impurities. S3. Turn on the lower motor 204 to drive the bidirectional lead screw 214 to rotate, which drives the two sets of nut seats 217 to move in opposite directions, thereby driving multiple sets of strip brushes 202 to move in opposite directions, so that the strip brushes 202 adjust the contact pressure of the mass transfer element 109. S4. After passing through the mass transfer element 109, the flue gas enters the area above the mass transfer element 109 and is rinsed by the cleaning liquid sprayed out by the washing nozzle 103. Then the gas mist enters the demister 105 and the demister 105 removes the liquid droplets in the gas mist state. Subsequently, the clean gas is discharged from the top of the scrubbing tower 106. The scrubbing tower 106 in step S1 includes a mass transfer element 109 installed inside the scrubbing tower 106 and a demisting flushing water skid system outside the scrubbing tower 106. The system automatically flushes according to the pressure difference of the demister 105 and also has a timed flushing program. During normal operation, the system flushes at regular intervals, and when the pressure difference exceeds the limit, it immediately flushes until the pressure difference is normal. The scrubbing tower 106 employs low-pressure, low-flow nozzles, extending nozzle lifespan several times over. Damage to individual nozzles does not affect scrubbing efficiency. Due to full utilization of the scrubbing liquid, the scrubbing liquid flow rate is reduced, resulting in approximately 90% reduction in scrubbing pump power, approximately 80% reduction in total energy consumption, and approximately 10-fold increase in scrubbing efficiency. System reliability and stability are also enhanced. The scrubbing tower 106 includes a de-entraining device characterized by high efficiency, low clogging, and low pressure drop, effectively removing the scrubbing agent entrained in the gas. The mass transfer element 109 is based on patent application number 2019213725. The mass transfer element 109 in 05.5 has multiple sets of star-shaped holes inside for the passage of flue gas, simultaneously mixing the flue gas and washing liquid into an aerosol state. The mass transfer element 109 is equipped with a cleaning mechanism. When the rotating column 201 rotates, its outer wall restraint strip 215 guides two sets of mounting rings 219 to rotate synchronously. The mounting rings 219 drive multiple sets of brushes 202 fixed thereon to rotate, cleaning impurities adhering to the bottom surface of the mass transfer element 109. The cleaning mechanism includes: A rotating column 201, located inside the mass transfer element 109, and multiple sets of brushes 202 located outside the rotating column 201, rotate. The ends of the brushes 202 can extend into the star-shaped hole to clean impurities adhering to the inner wall of the star-shaped hole. Simultaneously, when the brushes 202 rotate, they can contact multiple sets of extended bristles 203 on the mass transfer element 109. The extended bristles 203 contact clean impurities adhering to the soft bristles in the brushes 202, and the soft bristles can also clean impurities adhering to the extended bristles 203. Through this mutual cleaning, they achieve... The soft bristles and extended bristles 203 on the strip brush 202 are self-cleaning. Two sets of limiting strips 215 are fixedly installed on the outer wall of the rotating column 201. Two sets of mounting rings 219 are slidably installed on the outside of the rotating column 201 and the limiting strips 215. The end of the strip brush 202 is fixed on the mounting ring 219. The inner walls of the mounting ring 219 and the sliding ring are provided with limiting grooves for the end of the limiting strip 215 to pass through. Multiple sets of extended bristles 203 are fixedly installed on the top and bottom of the mass transfer component 109. The multiple sets of extended bristles 203 are arranged in a straight line to form a straight line shape. A sliding ring is sleeved on the outside of the rotating column 201. When the rotating column 201 rotates, the sliding ring slides in the fixed bearing 216, which neither hinders the rotation of the rotating column 201 nor restricts its lateral displacement. The fixed bearing 216 is fixedly installed on the outside of the sliding ring and is fixed inside the mass transfer element 109. An upper bevel gear 210 is fixedly installed on the outer top of the rotating column 201. An upper bevel gear 209 meshes with the outer side of the upper bevel gear 210. An upper rotating rod 205 is rotatably installed inside the washing tower 106. An upper motor 208 is fixedly installed on the outer side of the washing tower 106. One end of the upper rotating rod 205 is fixedly connected to the upper bevel gear 209, and the other end of the upper rotating rod 205 is fixedly connected to the working end of the upper motor 208. A conical box 200 is installed outside the upper bevel gear 210 and the upper bevel gear 209. The conical box 200 protects each bevel gear, extends its service life, and prevents impurities from entering the bevel gear meshing point and causing wear. A central rotating rod 206 is fixedly installed between the conical box 200 and the inner wall of the mass transfer component 109.

[0022] Example 2 Please refer to Example 1. Figures 1-5 The rotating column 201 is externally provided with an adjusting component for adjusting the spacing between multiple sets of strip brushes 202. The adjusting component includes: A bidirectional lead screw 214, rotatably mounted on the outside of the rotating column 201, passes through a connecting bearing 218 and can rotate independently of the rotating column 201. When the rotating column 201 rotates, the connecting bearing 218 rotates synchronously with the rotating column 201 without obstructing the rotation of the bidirectional lead screw 214 itself. When the bidirectional lead screw 214 rotates on the outside of the rotating column 201, the positive and negative threads on its surface drive two sets of nut seats 217 to move in opposite directions along the lead screw. Two sets of nut seats 217 are provided on the outside of the bidirectional lead screw 214. Annular brushes are fixedly mounted on the top and bottom of each nut seat 217. As the nut seats 217 move along the bidirectional lead screw 214, the annular brushes clean impurities adhering to the bidirectional lead screw 214 (the surface of the bidirectional lead screw 214 that the nut seats 217 are about to pass over). The nut seat 217 is fixedly connected to the outer wall of the mounting ring 219, and the mounting ring 219 is fixedly connected to the nut seat 217. Therefore, the mounting ring 219 slides on the rotating column 201 and the limiting strip 215 with the nut seat 217, thereby driving the strip brush 202 to move. The spacing between multiple sets of strip brushes 202 is adjusted. By adjusting the spacing of the strip brushes 202, the contact pressure between them and the mass transfer component 109 is changed to adapt to the degree of impurity adhesion, improve cleaning flexibility, and at the same time reduce the pressure of the soft bristles on the strip brush 202 when they contact the mass transfer component 109. This reduces the wear caused by excessive pressure on the soft bristles when they contact the mass transfer component 109, and also reduces the situation where the cleaning effect is poor due to insufficient pressure on the surface of the mass transfer component 109. Two sets of connecting bearings 218 are fixedly installed on the outer wall of the rotating column 201, and the bidirectional screw 214 is rotatably installed inside the connecting bearings 218. An outer bearing 213 is also fixedly fitted on the outside of the rotating column 201. A lower bevel gear 212 is fixedly installed on the outer wall of the outer bearing 213. A lower bevel gear 211 meshes with the outer wall of the lower bevel gear 212. A lower rotating rod is rotatably installed inside the washing tower 106. A lower motor 204 is fixedly installed on the outer wall of the washing tower 106. One end of the lower rotating rod is fixedly connected to the lower bevel gear 211, and the other end of the lower rotating rod is fixedly connected to the working end of the lower motor 204.

[0023] Example 3 Please refer to Example 2. Figures 1-5The washing tower 106 is equipped with two sets of limiting components. In the non-cleaning state, the upper rotating rod 205 is fixed to limit the rotating column 201, preventing the upper motor 208 from being accidentally started, which would cause the rotating column 201 and the strip brush 202 to rotate, thus improving the stability of operation. Moreover, during operation, the lower rotating rod can be fixed to prevent the lower motor 204 from being accidentally started, which would cause the bidirectional lead screw 214 to rotate and change the spacing between the multiple sets of strip brushes 202. The limiting components include a hydraulic rod 300 fixed on the washing tower 106. The working end of the hydraulic rod 300 is fixedly provided with a limiting rod 301, and the end of the limiting rod 301 can contact the upper rotating rod 205 and the lower rotating rod.

[0024] In this embodiment, two sets of spray pipes 108 are fixedly installed on the inner wall of the scrubbing tower 106. The scrubbing nozzles 103 are vortex nozzles at the front and rear ends of the spray pipes 108, and spiral nozzles in the middle. The spray pipes 108 on the inner wall of the scrubbing tower 106 deliver the cleaning liquid to the multiple sets of scrubbing nozzles 103 at the bottom. The scrubbing nozzles 103 spray the cleaning liquid to rinse the surface of the mass transfer element 109. Multiple sets of scrubbing nozzles 103 are fixedly installed at the bottom of the spray pipes 108. Multiple sets of support plates 104 are fixedly installed on the inner wall of the scrubbing tower 106. The support plates 104 are fixed to the inner wall of the scrubbing tower 106 to support the demister 105. A demisting resistance detection device is provided to detect the upper and lower pressures of the demister 105, the pressure difference, and the gas flow rate change of the demister 105. When the flow rate increases, the resistance increases, and the pressure difference between the upper and lower parts of the demister 105 increases. The demister 105 processes the incoming gas mist and separates the liquid droplets. The demister 105 is fixedly installed on the support plate 104. Two sets of connecting pipes are fixedly installed on the inner wall of the top of the scrubbing tower 106. Multiple sets of flushing nozzles 107 are fixedly installed at the bottom of the connecting pipes. The connecting pipes on the inner wall of the top of the scrubbing tower 106 deliver flushing water to the multiple sets of flushing nozzles 107 at the bottom. The flushing nozzles 107 spray liquid to flush the deposits on the surface of the support plate 104.

[0025] In this embodiment, a rinsing water tank 100 is provided on one side of the washing tower 106. A left pipe is provided on the rinsing water tank 100 and connected to the connecting pipe. A right pipe is provided on the other side of the washing tower 106. One end of the right pipe is connected to the end of the spray pipe 108, and the other end of the right pipe is connected to the bottom of the washing tower 106. Two sets of water pumps and filters are respectively provided on the right pipe. The filters can filter the liquid with impurities flowing out from the bottom of the washing tower 106 and filter the impurities. The water pumps can make the filtered water flow back into the washing nozzle 103 for continued use. The filter is located below the washing tower 106.

[0026] Working principle and usage process of this invention: When in use, external flue gas enters the scrubbing tower 106 after passing through the venturi tube 101 and the flue 102. The flue gas first flows through the mass transfer element 109. The star-shaped holes inside the mass transfer element 109 make the flue gas flow evenly and at the same time mix with the scrubbing liquid to form an aerosol state (enhancing the gas-liquid reaction efficiency). After passing through the mass transfer element 109, the flue gas rises. The spray pipe 108 sprays the filtered liquid transported by the right pipe through the scrubbing nozzle 103 to wash away some residual impurities on the surface of the mass transfer element 109. Then the aerosol enters the demister 105, which separates the liquid droplets in the aerosol. The flushing water tank 100 transports water to the connecting pipe through the left pipe. The flushing nozzle 107 at the bottom of the connecting pipe sprays liquid to wash away the impurities deposited on the surface of the support plate 104. When impurities adhere to the bottom of the mass transfer component 109 and the star-shaped hole, the upper motor 208 starts, and its working end drives the upper rotating rod 205 to rotate. The upper rotating rod 205 drives the rotating column 201 to rotate through the meshing transmission of the upper bevel gear 1 209 and the upper bevel gear 210. When the rotating column 201 rotates, the limiting strip 215 on the outer wall guides the mounting ring 219 to rotate synchronously. The mounting ring 219 drives the strip brush 202 to rotate. The strip brush 202 extends into the star-shaped hole to clean impurities and remove impurities attached to the upper and lower surfaces of the mass transfer component 109. At the same time, it contacts the extended hair 203 of the mass transfer component 109, and the two clean each other (to avoid impurity residue). The conical box 200 is fixed by the central rotating rod 206 to protect the upper bevel gear 1 209 and the upper bevel gear 210 from wear caused by impurity contamination. If it is necessary to adjust the contact pressure between the brush 202 and the mass transfer element 109, the lower motor 204 is started, and its working end drives the lower rotating rod to rotate. The lower rotating rod drives the outer bearing 213 to rotate through the meshing of the lower bevel gear 1 211 and the lower bevel gear 212. The outer bearing 213 drives the double-acting screw 214 to rotate. The double-acting screw 214 rotates independently of the rotating column 201 through the connecting bearing 218. The positive and negative threads on its surface drive the nut seat 217 to move in opposite directions. The nut seat 217 drives the brush 202 to move through the mounting ring 219. At this time, the brush 202 and the mass transfer element 109 move closer or further apart, realizing the adjustment of the spacing and pressure. In the non-cleaning state, by opening the hydraulic rod 300 located above the upper motor 208, the working end of the hydraulic rod 300 extends outward, driving the limiting rod 301 to move and extend. Then, the end of the limiting rod 301 contacts and locks the upper rotating rod 205, which can limit the upper rotating rod 205, thereby limiting the rotating column 201 and preventing the upper motor 208 from starting unexpectedly, causing the rotating column 201 and the strip brush 202 to rotate, thus improving the stability during use. During operation, the lower rotating rod can be fixed and limited to prevent the lower motor 204 from starting unexpectedly, which would cause the bidirectional lead screw 214 to rotate and change the spacing between multiple sets of strip brushes 202, affecting the cleaning effect. When limiting the lower rotating rod, the lower motor 204 located below the lower motor 204 is started. The working end of the lower motor 204 extends outward, driving the limiting rod 301 to extend. Then, the end of the limiting rod 301 contacts and clamps the lower rotating rod, thus limiting the lower rotating rod.

[0027] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
