Description

Technical Field

[0001] This invention relates to the field of chemical exhaust gas treatment technology, and in particular to a dynamic wave scrubber and its usage method. Background Technology

[0002] Flue gas desulfurization is divided into dry desulfurization and wet desulfurization. Dry desulfurization uses powdered or granular absorbents or catalysts, while wet desulfurization uses absorbents such as water or alkaline solutions to remove acidic substances such as SO2 from the exhaust gas. Currently, wet desulfurization is the most widely used method, mainly utilizing the full contact between gas and liquid to increase the probability of collision between the absorbent and pollutants, thereby improving the desulfurization efficiency of the equipment.

[0003] Application No. CN202011102206.7 discloses a high-efficiency reverse washing device for the production of sponge titanium. When the second rotating rod contacts the protrusion on the limiting block, a reaction force pushes the second rotating rod to move in the opposite direction, causing the second rotating rod to turn, thereby driving the washing nozzle to turn. This process is repeated, causing the washing nozzle to move back and forth, which increases the contact area between the liquid and the gas and achieves a better reverse washing effect.

[0004] Application No. CN201920709241.1 discloses a dynamic wave scrubbing flue gas dust removal and desulfurization device. The device sprays scrubbing liquid through nozzles, and at the same time, an electric telescopic rod drives the nozzles to move left and right, which can adjust the spray angle of the nozzles and expand the spray area of ​​the scrubbing liquid. This allows the scrubbing liquid to come into more full contact with the flue gas, thereby improving the purification effect of the device.

[0005] Although existing desulfurization devices can improve the contact effect between the scrubbing liquid and the flue gas to a certain extent, they require the installation of multiple nozzles in practical applications. At the same time, the spray area is relatively narrow, which cannot fully react with the flue gas and thus cannot meet people's requirements for flue gas purification.

[0006] Therefore, it is necessary to invent a dynamic wave washer and its usage method to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a dynamic wave scrubber and its usage method to solve the technical problem mentioned in the background art, which is that the spray area of ​​the nozzle inside the tower body is narrow and cannot fully react with the flue gas.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A dynamic wave scrubber includes a tower body. A scrubbing pipe communicating with the interior of the tower body is fixedly connected to the side wall of the tower body. A water pump is connected to the bottom of the tower body via a conduit. The water pump is connected to a water supply pipe via a conduit, which is located inside the scrubbing pipe. A rotating head is rotatably connected to the top of the water supply pipe. The top of the rotating head has an array of spray holes. An adjustment component for controlling the size of the spray holes is located above the rotating head. A drive component for driving the rotating head to rotate and for driving the adjustment component to move is located inside the rotating head. The adjustment component includes an array of sliders located above the rotating head. The slider has a connecting hole corresponding to the water spray hole inside. An elastic hose is provided between the water spray hole and the connecting hole. One end of the elastic hose is fixedly connected to the bottom of the water spray hole, and the other end of the elastic hose is fixedly connected to the top of the connecting hole. A limit block is fixedly connected to one end of the slider near the center of the water supply pipe. A wedge block is fixedly connected to one end of the limit block, and a stop block is fixedly connected to the middle of the limit block. A sleeve is connected to the stop block and the slider through an elastic element. A limiting groove corresponding to the limit block is provided on the sleeve. The outer wall of the sleeve is connected to the rotating head through a locking component. The sleeve covers the top of the drive component. Both the spray hole and the connecting hole are inclined holes, and the inclination angle and inclination direction of the spray hole and the connecting hole are consistent. One end of the spray hole faces the inner wall of the tower body, and the other end faces the center of the tower body. The slider is driven by the drive device to slide on the top of the rotating head. The bottom of the slider is in contact with the top of the rotating head, so that the connecting hole on the slider gradually coincides with the spray hole on the rotating head. Thus, the spray pressure of the washing liquid under different working conditions can be controlled by controlling the overlap range of the connecting hole and the spray hole.

[0010] Preferably, the drive assembly includes a water wheel fixedly connected to the inner wall of the bottom of the rotating head. A telescopic assembly is fixedly connected to the middle of the water wheel, a top block is fixedly connected to the top of the telescopic assembly, and a conical head is fixedly connected to the top of the top block. An array of limiting grooves is formed on the outer wall of the conical head, and the limiting grooves are adapted to the wedge-shaped blocks. The telescopic assembly can be configured as an electric push rod or a hydraulic push rod, etc. By controlling the extension of the telescopic assembly, the limiting grooves on the conical head press against the wedge-shaped blocks and the limiting blocks, thereby causing the slider to slide on the top of the rotating head. This causes the connecting hole on the slider to gradually coincide with the water spray hole on the rotating head. The overlap range between the connecting hole and the water spray hole is controlled by controlling the extension and retraction of the telescopic assembly.

[0011] Preferably, the wedge block includes a large head and a small head. The large head is located inside the limiting groove. One end of the small head is fixedly connected to the large head, and the other end of the small head is fixedly connected to the end of the limiting block away from the slider. The large head is inclined, and the inclination angle of the large head is consistent with the inclination angle of the conical head. The limiting groove is also inclined, and the inclination angle of the limiting groove is consistent with the inclination angle of the conical head.

[0012] Preferably, the inner wall of the flexible hose is provided with a spiral guide groove. By providing a spiral guide groove on the inner wall of the flexible hose, the washing liquid rotates through the spiral guide groove during the spraying process. This increases the outlet speed of the washing liquid when it is sprayed from the end of the flexible hose connected to the connecting hole, and at the same time increases the range of the washing liquid rotation and dispersion, fully reaching and impacting the entire washing pipe plane, thus achieving a better spraying effect.

[0013] Preferably, the flexible hose has a small hole in the middle, with the water outlet of the small hole facing the inner wall of the washing tube. By controlling the extension of the telescopic component, the slider is disengaged from the top of the rotating head, thereby stretching the flexible hose. During the stretching process, the diameter of the small hole in the middle of the flexible hose is enlarged, allowing the washing liquid to spray out from the small hole, thus expanding the spray range of the washing liquid.

[0014] Preferably, a sleeve is fixedly connected to the bottom of the top block, and the inner ring of the sleeve is slidably and sealingly connected to the fixed end of the telescopic assembly. By providing the sleeve, washing liquid is prevented from entering the connection between the fixed and movable ends of the telescopic assembly, thus avoiding damage to the telescopic assembly.

[0015] Preferably, the top of the tower body is provided with an exhaust port, the interior of the tower body is provided with a demister, a water inlet pipe is fixedly connected to the outer wall of the tower body, the water inlet pipe is located below the demister, and the bottom of the tower body is provided with a drain port. After the flue gas and liquid momentum reach equilibrium, preliminary gas-liquid separation occurs in the scrubbing pipe. The liquid and solid mixture falls to the bottom of the tower body and flows out from the drain port. The flue gas is redirected and passes from bottom to top through the demister inside the tower body to remove the liquid droplets remaining in the flue gas, and is discharged from the exhaust port.

[0016] Preferably, the number of demisters is set to two, and both demisters are equipped with an electric heating device inside. By incorporating an electric heating device inside the demister, the demister can more effectively remove liquid droplets remaining in the flue gas.

[0017] Preferably, a control terminal is provided on the outside of the tower body, and a control system is provided inside the control terminal. The control system is used to control the electrical components on the device.

[0018] A method of using a dynamic wave washer, the method being used with any of the aforementioned dynamic wave washers, the method comprising the following steps:

[0019] S1: The control system controls the external water supply device to input washing liquid into the tower body through the water inlet pipe, and the liquid level is set below the connection between the washing pipe and the tower body; the control system controls the electric heating device inside the demister to preheat.

[0020] S2: The control system controls the operation of the water pump, so that the washing liquid is sprayed out from the elastic hose on the rotating head through the water supply pipe; the control system controls the external flue gas pipe to discharge flue gas into the interior of the washing pipe; the flue gas enters from the top of the washing pipe and flows from top to bottom, while the washing liquid is sprayed from bottom to top. The washing liquid and the flue gas come into counter-current contact, and the collision between the flue gas and the washing liquid generates a turbulent zone. Rapid and continuous heat exchange occurs on the surface of the flue gas and the liquid in the turbulent zone.

[0021] S3: The control system controls the telescopic component to extend and retract, causing the limiting groove on the conical head to squeeze the wedge block, causing the slider to gradually move towards the inner wall of the tower, and then causing the connecting hole on the slider to gradually overlap with the water spray hole on the rotating head, thereby restoring the elastic hose between the connecting hole and the water spray hole from the squeezed state to the flat state.

[0022] S4: After the momentum of the flue gas and liquid is balanced, preliminary gas-liquid separation is carried out in the scrubbing tube. The liquid and solid mixture falls to the bottom of the tower. The flue gas is turned and passes from bottom to top through two sets of demisters inside the tower to remove the liquid droplets remaining in the flue gas.

[0023] The technical effects and advantages of this invention are as follows:

[0024] 1. This invention, by setting up a telescopic component and an adjustment component, allows the control system to control the telescopic component to reciprocate and retract. Since the large head of the wedge block is located inside the limiting groove, when the control system controls the telescopic component to reciprocate and retract, the conical head drives the slider to reciprocate and reciprocate along the joint between the limiting block and the sleeve through the large head of the wedge block. This ensures that the connecting hole on the slider and the water spray hole on the rotating head are always in a cyclical state of first coinciding and then misaligning, so that the washing liquid sprayed from the elastic hose presents a pulsed form, thereby ensuring that the vapor and liquid phases are fully mixed.

[0025] 2. This invention, by setting up a telescopic component and an elastic hose, and controlling the telescopic component to extend, causes the slider to gradually disengage from the rotating head. As the slider moves upward, the elastic hose between the connecting hole and the spray hole is stretched. During the stretching process, the diameter of the elastic hose in the middle decreases while the diameters at both ends remain unchanged. This disrupts the stress structure of impurities adhering to the inner wall of the elastic hose, increasing the pressure of the washing liquid entering the elastic hose, thereby removing impurities adhering to the inner wall of the elastic hose.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0037] Reference Figures 1 to 9 A dynamic wave scrubber includes a tower body 1. A scrubbing pipe 2, communicating with the interior of the tower body 1, is fixedly connected to the side wall of the tower body 1. A water pump 3 is connected to the bottom of the tower body 1 via a conduit. The water pump 3 is connected to a water supply pipe 4 via a conduit. The water supply pipe 4 is located inside the scrubbing pipe 2. A rotating head 5 is rotatably connected to the top of the water supply pipe 4. The top of the rotating head 5 has an array of spray holes 6. An adjustment component 7 for controlling the size of the spray holes 6 is located above the rotating head 5. A drive component 8 for driving the rotating head 5 to rotate and for driving the adjustment component 7 to move is located inside the rotating head 5. The adjustment component 7 includes an array of sliders 701 located above the rotating head 5. The sliders 701 have openings corresponding to the spray holes 6 inside. A flexible hose 703 is provided between the connecting hole 702 and the water spray hole 6. One end of the flexible hose 703 is fixedly connected to the bottom of the water spray hole 6, and the other end of the flexible hose 703 is fixedly connected to the top of the connecting hole 702. A limit block 704 is fixedly connected to one end of the slider 701 near the center of the water supply pipe 4. A wedge block 705 is fixedly connected to one end of the limit block 704. A stop block 706 is fixedly connected to the middle of the limit block 704. A sleeve 708 is connected between the stop block 706 and the slider 701 through an elastic element 707. A limiting groove corresponding to the limit block 704 is opened on the sleeve 708. The outer wall of the sleeve 708 is connected to the rotating head 5 through a locking component. The sleeve 708 covers the top of the drive component 8. Both the spray hole 6 and the connecting hole 702 are inclined holes. The inclination angle and inclination direction of the spray hole 6 and the connecting hole 702 are the same. One end of the spray hole 6 faces the inner wall of the tower body 1, and the other end of the spray hole 6 faces the center of the tower body 1. The slider 701 is driven by the driving device to slide on the top of the rotating head 5. The bottom of the slider 701 is in contact with the top of the rotating head 5, so that the connecting hole 702 on the slider 701 gradually coincides with the spray hole 6 on the rotating head 5. Thus, the spray pressure of the washing liquid under different working conditions can be controlled by controlling the overlap range of the connecting hole 702 and the spray hole 6.

[0038] Specifically, the drive assembly 8 includes a water wheel 801 fixedly connected to the inner wall of the bottom of the rotating head 5. A telescopic assembly 802 is fixedly connected to the middle of the water wheel 801, a top block 803 is fixedly connected to the top of the telescopic assembly 802, and a conical head 804 is fixedly connected to the top of the top block 803. The outer wall of the conical head 804 is provided with arrayed limiting grooves 805, which are adapted to the wedge block 705. The telescopic assembly 802 can be configured as an electric push rod or a hydraulic push rod, etc. By controlling the extension of the telescopic assembly 802, the limiting grooves 805 on the conical head 804 squeeze the wedge block 705 and the limiting block 704, thereby causing the slider 701 to slide on the top of the rotating head 5, so that the connecting hole 702 on the slider 701 gradually coincides with the water spray hole 6 on the rotating head 5. By controlling the extension and retraction of the telescopic assembly 802, the overlap range between the connecting hole 702 and the water spray hole 6 is controlled.

[0039] Specifically, the wedge block 705 includes a large head 7051 and a small head 7052. The large head 7051 is located inside the limiting groove 805. One end of the small head 7052 is fixedly connected to the large head 7051, and the other end of the small head 7052 is fixedly connected to the end of the limiting block 704 away from the slider 701. The large head 7051 is inclined, and the inclination angle of the large head 7051 is consistent with the inclination angle of the conical head 804. The limiting groove 805 is also inclined, and the inclination angle of the limiting groove 805 is consistent with the inclination angle of the conical head 804.

[0040] Specifically, the inner wall of the flexible hose 703 is provided with spiral guide grooves 9. By providing spiral guide grooves 9 on the inner wall of the flexible hose 703, the washing liquid rotates through the spiral guide grooves 9 during the spraying process. This increases the outlet speed of the washing liquid when it is sprayed from the end of the flexible hose 703 connected to the connecting hole 702, and at the same time increases the range of the washing liquid rotation and dispersion, so that it can fully reach and impact the entire plane of the washing pipe 2, achieving a better spraying effect.

[0041] Specifically, the flexible hose 703 has a small hole 10 in the middle, with the water outlet of the small hole 10 facing the inner wall of the washing tube 2. By controlling the extension of the telescopic component 802, the slider 701 is disengaged from the top of the rotating head 5, thereby stretching the flexible hose 703. During the stretching process, the diameter of the small hole 10 in the middle of the flexible hose 703 is enlarged, and the washing liquid can be sprayed out from the small hole 10, thereby expanding the spray range of the washing liquid.

[0042] Specifically, a sleeve 11 is fixedly connected to the bottom of the top block 803, and the inner ring of the sleeve 11 is slidably and sealingly connected to the fixed end of the telescopic component 802. By setting the sleeve 11, the washing liquid is prevented from entering the connection between the fixed end and the movable end of the telescopic component 802, thus preventing damage to the telescopic component 802.

[0043] Specifically, the top of the tower body 1 is provided with an exhaust port 12, the inside of the tower body 1 is provided with a demister 13, and a water inlet pipe 14 is fixedly connected to the outer wall of the tower body 1, located below the demister 13. The bottom of the tower body 1 is provided with a drain port 15. After the momentum of the flue gas and liquid is balanced, preliminary gas-liquid separation is carried out in the washing pipe 2. The liquid and solid mixture falls to the bottom of the tower body 1 and flows out from the drain port 15. The flue gas is turned and passes from bottom to top through the demister 13 inside the tower body 1 to remove the liquid droplets remaining in the flue gas, and is discharged from the exhaust port 12.

[0044] Specifically, the number of demisters 13 is set to two, and both demisters 13 are equipped with electric heating devices inside. By installing electric heating devices inside the demisters 13, the demisters 13 can better remove liquid droplets remaining in the flue gas.

[0045] Specifically, a control terminal is installed on the outside of the tower body 1, and a control system is installed inside the control terminal. The control system is used to control the electrical components on the device.

[0046] The washing pipe 2 is equipped with a smoke sensor inside, and a solenoid valve is installed at the drain outlet 15. The locking component is an electromagnetic pin. In the initial state, the solenoid valve in the drain outlet 15 is in the closed state; when the locking component pops out, the outer wall of the sleeve 708 and the top of the rotating head 5 are locked.

[0047] In operation, the control system controls the external water supply device to input washing liquid into the tower body 1 through the inlet pipe 14. When the washing liquid injected into the tower body 1 reaches the set level, the control system controls the external water supply device to stop supplying water, and the level is set below the connection between the washing pipe 2 and the tower body 1. Then, the control system simultaneously controls the operation of the electric heating device inside the demister 13 and the water pumping assembly 3. The electric heating device preheats the demister 13, and the water pumping assembly 3 transports the washing liquid to the water supply pipe 4 through the conduit. The washing liquid entering the water supply pipe 4 is sprayed out from the elastic hose 703 on the rotating head 5. The control system controls the external flue gas pipe to discharge flue gas into the washing pipe 2. Since the flue gas flows from top to bottom in the washing pipe 2, and the washing liquid flows from top to bottom in the washing pipe... The trajectory of the jet in section 2 is from bottom to top, which causes the washing liquid and flue gas to come into countercurrent contact in the washing pipe 2. The collision between the flue gas and the washing liquid creates a turbulent zone, where rapid and continuous heat exchange occurs on the surface of the flue gas and liquid in the turbulent zone. When the momentum of the flue gas and liquid is balanced, the flue gas and liquid undergo preliminary gas-liquid separation in the washing pipe 2. The liquid and solid mixture falls to the bottom of the tower body 1 and is transported again to the water supply pipe 4 through the water pumping assembly 3, and then sprayed out from the elastic hose 703 for recycling. The purified flue gas is redirected and passes from bottom to top through two sets of demisters 13 inside the tower body 1 to remove the liquid droplets remaining in the flue gas. The electric heating device in the demister 13 heats and removes the liquid droplets remaining in the flue gas, thereby enabling the demister 13 to better remove the liquid droplets in the flue gas.

[0048] As the washing liquid in the water pipe 4 flows towards the spray hole 6 at the top of the rotating head 5, it first contacts the water wheel 801 at the bottom of the rotating head 5. The washing liquid drives the water wheel 801 to rotate, and as the water wheel 801 rotates, it synchronously drives the rotating head 5 to rotate. Since the outer wall of the sleeve 708 is locked to the top of the rotating head 5 at this time, and the limiting block 704 is slidably connected to the sleeve 708 through the limiting groove, the rotating head 5 drives the slider 701 to rotate synchronously through the sleeve 708 and the limiting block 704 during rotation. After the washing liquid enters the interior of the rotating head 5, it flows from the top of the rotating head 5. The water sprays out from the nozzle. Because the amount of flue gas entering the washing pipe 2 is large, the pumping rate of the water pumping assembly 3 is increased by the flue gas sensor. However, it cannot quickly reach the rotating head 5, resulting in the washing liquid sprayed from the rotating head 5 not being able to fully absorb the flue gas. Therefore, when the flue gas sensor in the washing pipe 2 detects a large amount of flue gas entering the washing pipe 2, the control system controls the connecting hole 702 on the slider 701 and the water spray hole 6 on the rotating head 5 to be misaligned. That is, the middle of the elastic hose 703 between the connecting hole 702 and the water spray hole 6 is under compression (specifically as shown in...). Figure 7 and Figure 8(As shown); the large head 7051 of the wedge block 705 is located at the end of the limiting groove 805 near the top of the conical head 804. Simultaneously, because the kinetic energy generated by the washing liquid entering the rotating head 5 is relatively small, the rotational speed of the water wheel 801 inside the rotating head 5 is low, causing the telescopic component 802 to temporarily not move. This keeps the connecting hole 702 on the slider 701 and the spray hole 6 on the rotating head 5 misaligned, and the elastic hose 703 between the connecting hole 702 and the spray hole 6 is under compression (specifically as shown). Figure 8 As shown), one end of the flexible hose 703 is fixedly connected to the top of the connecting hole 702, and the other end is fixedly connected to the bottom of the spray hole 6. The middle part of the flexible hose 703 is in a movable state (the middle part of the flexible hose 703 is the squeezed part). Thus, after the washing liquid enters the rotating head 5, it is sprayed out through the flexible hose 703 between the connecting hole 702 and the spray hole 6. At the same time, since the flexible hose 703 is in a squeezed state at this time, and the flexible hose 703 has a spiral guide groove 9 inside, the squeezed part of the flexible hose 703 pressurizes the washing liquid entering the flexible hose 703, so that the flexible hose 703... The sprayed washing liquid has a wider range; the spiral guide groove 9 on the elastic hose 703 provides a rotational force to the washing liquid entering the elastic hose 703, thereby increasing the outlet speed when the washing liquid is sprayed out of the elastic hose 703, and increasing the range of the washing liquid rotation and dispersion, fully reaching and impacting the entire plane of the washing pipe 2, achieving a better spraying effect; at the same time, since the rotating head 5 and the sliding block are also rotating at this time, after the liquid is sprayed out, the small rotation in the elastic hose 703 and the large rotation of the rotating head 5, under the double superposition, the direction of the liquid jet is more complex, thereby achieving a better mixing effect between the vapor and liquid phases.

[0049] When the rotational speed of the washing liquid-driven water turbine 801 is increased (i.e., the water pressure inside the rotating head 5 is increased), the control system controls the telescopic component 802 to extend. The telescopic end of the telescopic component 802 drives the conical head 804 to move upward through the top block 803. During the upward movement of the conical head 804, the limiting groove 805 cooperates with the wedge block 705, causing the limiting block 704 to move towards the inner wall of the tower body 1. Since the large head 7051 of the wedge block 705 is inclined, and the inclination angle of the wedge block 705 is... The wedge block 705 is tilted at the same angle as the limiting groove 805, so that the wedge block 705 will not get stuck in the limiting groove 805 during the upward movement of the conical head 804; as the limiting block 704 moves toward the inner wall of the tower body 1, the stop block 706 squeezes the elastic element 707, causing the elastic element 707 to contract; at the same time, the limiting block 704 pushes the slider 701 toward the inner wall of the tower body 1, so that the connecting hole 702 on the slider 701 gradually coincides with the water spray hole 6 on the rotating head 5.

[0050] When the large head 7051 of the wedge block 705 is pressed by the conical head 804 and moves to the bottom of the limiting groove 805, the connecting hole 702 on the slider 701 completely overlaps with the water spray hole 6 on the rotating head 5. At this time, the elastic hose 703 located between the connecting hole 702 and the rotating head 5 returns to a flat state, thereby ensuring that the washing liquid sprayed from the elastic hose 703 expands the spray range while ensuring the spray range, so that the vapor and liquid phases are fully mixed.

[0051] The control system can control the contraction of the telescopic component 802 according to the actual working conditions of the tower body 1. For example, when the control system controls the telescopic component 802 to reciprocate, since the large head 7051 of the wedge block 705 is located inside the limiting groove 805, when the control system controls the telescopic component 802 to reciprocate, the conical head 804 drives the slider 701 to reciprocate along the joint between the limiting block 704 and the sleeve 708 through the large head 7051 of the wedge block 705. This makes the connecting hole 702 on the slider 701 and the spray hole 6 on the rotating head 5 always in a cycle of first overlapping and then misaligning, so that the washing liquid sprayed from the elastic hose 703 presents a pulse form, thereby making the vapor and liquid phases fully mixed.

[0052] After the flue gas washing is completed, the control system controls the telescopic component 802 to retract to its initial state. During the retraction of the telescopic component 802, under the influence of the elastic restoring force of the elastic element 705 and the inclination of the limiting groove 805, the slider 701 is pulled towards the sleeve 708, thereby causing the connecting hole 702 on the slider 701 to be misaligned with the water spray hole 6 on the rotating head 5 again, ready for the next use.

[0053] When the flexible hose 703 becomes clogged, the control system controls the locking assembly to retract, thereby releasing the locking state between the outer wall of the sleeve 708 and the top of the rotating head 5. Then, the control system controls the telescopic assembly 802 to extend. The telescopic end of the telescopic assembly 802 drives the conical head 804 upward via the top block 803. During the upward movement of the conical head 804, the wedge block 705 is displaced in the limiting groove 805, causing the limiting block 704 to move towards the inner wall of the tower body 1. When the large head 7051 of the wedge block 705 moves to the bottom of the limiting groove 805 under the pressure of the conical head 804, the connecting hole 702 completely overlaps with the spray hole 6. At this point, the control system... The system continues to control the extension of the telescopic component 802. Since the large head 7051 of the wedge block 705 is located inside the limiting groove 805, when the large head 7051 of the wedge block 705 moves to the bottom end of the limiting groove 805, the bottom end of the limiting groove 805 abuts against and limits the large head 7051 of the wedge block 705. At the same time, since the sleeve 708 and the rotating head 5 are in an unlocked state at this time, and the limiting block 704 is slidably connected to the sleeve 708 through the limiting groove, during the extension of the telescopic component 802, the telescopic component 802 drives the slider 701 to move upward through the conical head 804 and the sleeve 708, so that the slider 701 gradually disengages from the rotating head 5.

[0054] As the slider 701 moves upward, the elastic hose 703 between the connecting hole 702 and the spray hole 6 is stretched. Since one end of the elastic hose 703 is connected to the top of the connecting hole 702 and the other end is connected to the bottom of the spray pipe, the diameter of the middle part of the elastic hose 703 decreases during the stretching process, while the diameters at both ends of the elastic hose 703 remain unchanged. At this time, the shape of the elastic hose 703 takes the form of an hourglass. Due to the change in the inner diameter of the elastic hose 703, the stress structure of the impurities adhering to the inner wall of the elastic hose 703 is destroyed. At the same time, because the elastic hose 701 moves upward, the elastic hose 703 is stretched. The shape of 03 is hourglass-shaped, which increases the pressure of the washing liquid entering the flexible hose 703, thereby removing impurities adhering to the inner wall of the flexible hose 703. Since the flexible hose 703 has a small hole 10 in the middle, the diameter of the small hole 10 on the flexible hose 703 gradually increases during the stretching process. As the water outlet end of the small hole 10 faces the inner wall of the washing pipe 2, during the stretching process of the flexible hose 703, some washing liquid can be sprayed out from the small hole 10 and mix with the flue gas, reducing the phenomenon that the washing liquid cannot mix with the flue gas due to the blockage of the flexible hose 703.

[0055] This invention also provides a method of using a dynamic wave washer, the method comprising the following steps:

[0056] S1: The control system controls the external water supply device to input washing liquid into the tower body 1 through the water inlet pipe 14, and the liquid level is set below the connection between the washing pipe 2 and the tower body 1; the control system controls the electric heating device inside the demister 13 to preheat.

[0057] S2: The control system controls the operation of the water pump 3, so that the washing liquid is sprayed out from the elastic hose 703 on the rotating head 5 through the water supply pipe 4; the control system controls the external flue gas pipe to discharge flue gas into the interior of the washing pipe 2; the flue gas enters from the top of the washing pipe 2 and flows from top to bottom, while the washing liquid is sprayed from bottom to top. The washing liquid and the flue gas come into counter-current contact, and the collision between the flue gas and the washing liquid generates a turbulent zone. Rapid and continuous heat exchange occurs on the surface of the flue gas and the liquid in the turbulent zone.

[0058] S3: The control system controls the telescopic component 802 to extend and retract, causing the limiting groove 805 on the conical head 804 to press against the wedge block 705, causing the slider 701 to gradually move towards the inner wall of the tower body 1, thereby causing the connecting hole 702 on the slider 701 to gradually overlap with the water spray hole 6 on the rotating head 5, thus causing the elastic hose 703 between the connecting hole 702 and the water spray hole 6 to return from the compressed state to the flat state.

[0059] S4: After the momentum of the flue gas and liquid is balanced, preliminary gas-liquid separation is carried out in the scrubbing pipe 2. The liquid and solid mixture falls to the bottom of the tower body 1. The flue gas is turned and passes from bottom to top through the two sets of demisters 13 inside the tower body 1 to remove the liquid droplets left in the flue gas.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
