Description

Technical Field

[0001] This application relates to the technical field of exhaust gas treatment, and in particular to a continuous water replenishment device for a gas scrubbing tower. Background Technology

[0002] A gas scrubbing tower is a common gas purification device in industrial production processes, frequently used in petrochemical, electronics, and pharmaceutical fields. During gas purification, the gas is drawn into the tower and passes through a scrubbing device. This device sprays a detergent onto the gas, and upon contact with the detergent, harmful components in the gas react chemically with and are absorbed by the detergent, thus achieving gas purification.

[0003] During the operation of the gas scrubbing tower, it is necessary to replenish the washing device in the tower with water in a timely manner through a water replenishment device to ensure the continuous spraying action of the washing device on the gas inside the scrubbing tower. Currently, the water replenishment device is mainly activated by the operator, and when the water replenishment device is activated to replenish water to the washing device, the air bubbles generated during the water replenishment process will enter the spray pipe along with the spray from the washing device, thus affecting the gas scrubbing effect in the gas scrubbing tower. Utility Model Content

[0004] In order to reduce the impact of water replenishment on the scrubbing effect of the scrubbing tower, this application provides a continuous water replenishment device for the scrubbing tower.

[0005] The continuous water replenishment device for a gas scrubbing tower provided in this application adopts the following technical solution:

[0006] A continuous water supply device for a gas scrubbing tower includes:

[0007] The first water tank has a first water supply chamber inside, a first water supply pipe is arranged at the bottom of the first water supply chamber, and the first water supply pipe is connected to the top of the first water supply chamber.

[0008] The second water tank has a second water supply chamber inside, a second water supply pipe is arranged at the bottom of the second water supply chamber, and a second water supply pipe is connected to the top of the second water supply chamber.

[0009] The first water replenishment detection mechanism is installed inside the first water replenishment tank. The first water replenishment detection mechanism is used to control the closure of the first water supply pipe, the opening of the second water supply pipe, and the opening and closing of the first water replenishment pipe.

[0010] The second water replenishment detection mechanism is located inside the second water replenishment tank. The second water replenishment detection mechanism is used to control the opening of the first water supply pipe, the closing of the second water supply pipe, and the opening of the second water replenishment pipe.

[0011] By adopting the above technical solution, during the operation of the air scrubbing tower, the first and second water supply tanks jointly provide a continuous water supply to the scrubbing device of the air scrubbing tower, and the first and second water supply tanks are not in water supply state simultaneously. When the first water supply tank is in water supply state, if the water level in the first water supply tank is detected by the first water supply detection mechanism as being too low and requiring water replenishment, the first water supply detection mechanism controls the first water supply pipe to close and the second water supply pipe to open, thereby controlling the first water supply tank to stop supplying water to the scrubbing device, while the second water supply tank supplies water to the scrubbing device in the air scrubbing tower, and the first water supply pipe replenishes water to the first water supply tank. When the water level in the first water supply tank reaches the full level, the first water supply detection mechanism controls the first water supply pipe to close, stopping water replenishment to the first water supply tank. When the water level in the second water supply tank is too low and requires water replenishment, the second water supply detection mechanism controls the first water supply pipe to open and the second water supply pipe to close, and controls the second water supply pipe to open and replenish water to the second water supply tank. The first and second water supply tanks are automatically identified and alternately supply water to the washing device inside the air scrubbing tower. The alternating water supply of the first and second water supply tanks reduces the probability of air bubbles generated during water replenishment entering the washing device, thereby reducing the impact of water replenishment on the air scrubbing effect of the air scrubbing tower.

[0012] Optionally, the first water replenishment detection mechanism includes a first water level detection element, a first switch trigger element, a first water supply switch, and a first water replenishment control switch. One end of the first water level detection element is disposed in the first water replenishment chamber, and the other end of the first water level detection element is connected to the first switch trigger element. The first switch trigger element is used to control the first water supply switch and the first water replenishment control switch.

[0013] By adopting the above technical solution, when the first water replenishment detection mechanism is working, the first water level detection element detects the water level in the first water replenishment tank. When the water level in the first water replenishment tank is too low, the first water level detection element sends a signal to the first switch trigger element. The first switch trigger element controls the first water supply switch and the first water replenishment switch, so that the first water supply pipe stops supplying water to the air scrubbing tower, and the first water replenishment pipe starts replenishing water into the first water replenishment tank. When the water level in the first water replenishment tank reaches the full level, the first water level detection element sends a signal to the first switch trigger element, which causes the first water replenishment switch to close, and the first water replenishment pipe stops replenishing water into the first water replenishment tank.

[0014] Optionally, the first water level detection device includes a first water level float, a first pull rope, and a first rotating rod. The first water level float is connected to one end of the first pull rope, and the other end of the first pull rope is connected to one end of the first rotating rod. The side wall of the first rotating rod is hinged to the interior of the first water replenishment tank. The inner wall of the first water replenishment tank has a first control cavity. The other end of the first rotating rod is disposed in the first control cavity and connected to the first switch trigger.

[0015] By adopting the above technical solution, when the first water level detection device is working, the first water level float moves with the water level in the first water replenishment tank. The first pull rope is connected to the first water level float, so that when the first water level float reaches a specific position, the water level information is fed back to the first rotating rod, thereby realizing the detection of the water level at a specific position (replenishment water level and full water level) in the first water replenishment tank.

[0016] Optionally, the first switch trigger includes a positioning partition plate and a flexible trigger head. One side of the positioning partition plate is fixedly connected to the cavity wall of the first control cavity opposite to the first rotating rod. The side of the positioning partition plate facing the first rotating rod is connected to the flexible trigger head. The end face of the flexible trigger head is used to abut against the first rotating rod. The distance between the flexible trigger head and the rotation center of the first rotating rod is less than the length of the first rotating rod on the side facing the flexible trigger head at the rotation center. The first water supply switch and the first water replenishment control switch are connected to the cavity wall of the first control cavity at one end separated from the positioning partition plate. The first rotating rod is used to move to both ends of the positioning partition plate respectively.

[0017] By adopting the above technical solution, the first switch trigger divides the space of the first control cavity into two parts through the positioning partition plate. When the first rotating rod rotates, the flexible trigger head abuts against the first rotating rod. In its natural state, the first rotating rod cannot reach the other end of the positioning partition plate from one end. When the water level in the first water tank is too low and water needs to be added, the first water level float transmits force to the first rotating rod through the first pull rope, causing the first rotating rod to move to one end of the first water supply switch and the first water replenishment control switch and abut against them. The positioning partition plate keeps the first rotating rod abutting against the first water supply switch and the first water replenishment control switch, thereby stopping the first water tank from supplying water, starting the second water tank from supplying water, and maintaining the state of the first water replenishment pipe replenishing the first water tank. When the water level in the first water tank reaches full, the first water level float transmits force to the first rotating rod through the pull rope, causing the first rotating rod to separate from the first water replenishment control switch and rotate past the flexible trigger head to the other end of the positioning partition plate, stopping the first water replenishment pipe from replenishing the first water tank.

[0018] Optionally, the first water replenishment control switch is connected to a reset spring, one end of which is connected to the cavity wall of the first control chamber, and the other end of which is connected to the end of the first water replenishment control switch away from the cavity wall of the first control chamber.

[0019] By adopting the above technical solution, after the first rotating rod separates from the first water replenishment control switch, the first water replenishment control switch is reset by the reset spring, thereby changing the water replenishment state of the first water replenishment pipe.

[0020] Optionally, the first control chamber is located near the top of the first water supply tank.

[0021] By adopting the above technical solution, the first control chamber is positioned at the top of the first water supply tank, which reduces the contact time between the first control chamber and the water in the water supply tank, thereby reducing the probability of leakage of components in the first control box.

[0022] Optionally, the second water replenishment detection mechanism includes a second water level detection element, a second switch trigger element, a second water supply switch, and a second water replenishment control switch. One end of the second water level detection element is disposed in the second water replenishment chamber, and the other end of the second water level detection element is connected to the second switch trigger element. The second switch trigger element is used to trigger the second water supply switch and the second water replenishment control switch.

[0023] By adopting the above technical solution, when the second water replenishment tank replenishes water to the washing device in the air scrubbing tower, the water level of the second water replenishment tank is detected by the second water level detection device in the second water replenishment detection mechanism. The second water level detection device feeds back the water level signal in the second water replenishment tank to the second switch trigger, which controls the second water supply switch and the second water replenishment control switch to control the water supply status of the second water replenishment tank to the washing device and the water replenishment status of the second water replenishment pipe to the second water replenishment tank.

[0024] Optionally, the second water supply tank has a second control chamber inside. The structure of the second water level detection element is the same as that of the first water level detection element. The structure of the second switch trigger element is the same as that of the first switch trigger element. The second water supply switch and the first water supply switch are connected to the cavity wall of the second control chamber and are arranged apart from the positioning partition plate.

[0025] By adopting the above technical solution, a second control chamber is opened in the second water supply tank. The water level in the second water supply tank is detected by the water level detection and water supply method in the first water supply tank. When the water level in the second water supply tank is too low, the second water supply tank is notified to supply water to the washing device, and the first water supply tank starts supplying water to the washing device. After the second water supply tank stops supplying water to the washing device, water is replenished to the second water supply tank, so that the second water supply tank can supply water to the washing device next time.

[0026] Optionally, a continuous water replenishment device for a gas scrubbing tower further includes a control trigger plate. Both the first water replenishment tank and the second water replenishment tank are provided with control grooves. The control trigger plate is arranged in the control grooves. The control trigger plate is provided with a first connecting hole and a second connecting hole. The first connecting hole is used to connect to the first water supply pipe, and the second connecting hole is used to connect to the second water supply pipe. The distance between the first connecting hole and the second connecting hole is at least one diameter of the first water supply pipe from the distance between the first water supply pipe and the second water supply pipe. The control trigger plate is connected to a driving component, and the driving component is electrically connected to the first water supply switch and the second water supply switch.

[0027] By adopting the above technical solution, when the first rotating rod abuts against the first water supply switch, the driving component drives the control trigger plate to slide within the control groove, causing the first connecting hole to separate from the first water supply pipe. The control trigger plate then blocks the first water supply pipe, and the second connecting hole connects to the second water supply pipe, achieving the effect that the first water supply tank stops supplying water to the washing device, while the second water supply tank begins supplying water to the washing device. When the second rotating rod abuts against the second water supply switch, the driving component drives the control trigger plate to move in the opposite direction within the control groove, causing the first connecting hole to connect with the first water supply pipe, and the second connecting hole to separate from the second water supply pipe. The second water supply pipe is then blocked by the control trigger plate, achieving the effect that the second water supply tank stops supplying water to the washing device, while the first water supply tank opens and supplies water to the washing device.

[0028] Optionally, the driving component includes a driving motor and a driving gear, and the side wall of the control trigger plate is provided with driving engagement teeth. The driving gear meshes with the driving engagement teeth, and the first water supply switch and the second water supply switch are both electrically connected to the driving motor.

[0029] By adopting the above technical solution, when the drive component is working, the drive motor drives the drive gear to rotate, and the rotating drive gear meshes with the drive meshing teeth on the side wall of the control trigger plate, thereby achieving the effect of driving the control trigger plate to move.

[0030] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0031] 1. During the operation of the air scrubbing tower, water is supplied to the scrubbing device jointly by the first and second water supply tanks to ensure continuous water supply. The first and second water supply tanks operate independently. When the first water supply tank detects that its water level is too low and requires replenishment, the first water supply detection device controls the first water supply pipe to close and the second water supply pipe to open, thus stopping the first water supply tank from supplying water to the scrubbing device. The second water supply tank then begins supplying water to the scrubbing device and replenishes the first water supply tank. Conversely, when the water level in the second water supply tank is too low and requires replenishment, the second water supply detection device controls the second water supply pipe to close and the first water supply pipe to open, thus stopping the second water supply tank from supplying water to the scrubbing device. The first water supply tank then begins supplying water to the scrubbing device and replenishes the second water supply tank. Water is supplied to the washing device through the first water supply tank and the second water supply tank respectively. When the first water supply tank stops supplying water to the washing device, water is added to the first water supply tank, and when the second water supply tank stops supplying water to the washing device, water is added to the second water supply tank. This reduces the probability of air bubbles generated during water replenishment entering the washing device, thereby reducing the impact on the washing effect of the air scrubbing tower during the water replenishment process.

[0032] 2. The first water level detection device detects the water level in the first water supply tank through the first water level float. When the first water level float reaches the water supply level and the full water level, it can transmit force to the first rotating rod through the first pull rope, causing the first rotating rod to change its position at both ends of the positioning partition plate, thereby controlling the first water supply switch and the first water supply control switch, and realizing the control of the water supply status and water supply status in the first water supply tank;

[0033] 3. When the first water supply switch and the second water supply switch are working, an electrical signal is transmitted to the drive motor through an electrical connection. The drive motor drives the drive gear to rotate. The drive gear meshes with the drive meshing teeth, thereby driving the control trigger plate to slide in the control groove. By sliding in the control groove, the control trigger plate controls the connection status of the first connecting hole and the first water supply pipe, and the connection status of the second connecting hole and the second water supply pipe, thereby controlling the water supply status of the first water supply tank and the second water supply tank.

[0039] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0040] This application discloses a continuous water replenishment device for a gas scrubbing tower. (Refer to...) Figure 1 and Figure 2 A continuous water replenishment device for a gas scrubbing tower includes a first water replenishment tank 1, a second water replenishment tank 4, a first water replenishment detection mechanism 7, and a second water replenishment detection mechanism 8.

[0041] The first water supply tank 1 has a first water supply cavity 11, the bottom of which is connected to a first water supply pipe 2, and the top of which is connected to a first water supply pipe 3; the second water supply tank 4 has a second water supply cavity 41, the bottom of which is connected to a second water supply pipe 5, and the top of which is connected to a second water supply pipe 6; a first detection mechanism is installed in the first water supply tank 1, and the first water supply detection mechanism 7 controls the closing of the first water supply pipe 2, the connection of the second water supply pipe 5, and the opening and closing of the first water supply pipe 3; a second water supply detection mechanism 8 is installed in the second water supply tank 4, and the second water supply detection mechanism 8 controls the connection of the first water supply pipe 2, the closing of the second water supply pipe 5, and the opening and closing of the second water supply pipe 6.

[0042] During gas scrubbing in the scrubbing tower, the first water supply tank 1 and the second water supply tank 4 are alternately supplied to the scrubbing device inside the scrubbing tower by the first water supply detection mechanism 7 and the second water supply detection mechanism 8. When the water level in the first water supply tank 1 is too low, the first water supply detection mechanism 7 detects the water level and controls the first water supply pipe 2 to close, the second water supply pipe 5 to open, and the first water supply pipe 3 to open and supply water to the first water supply tank 1. When the water level in the second water supply tank 4 is too low, the second water supply detection mechanism detects the water level and controls the first water supply pipe 2 to open, the second water supply pipe 5 to close, and controls the second water supply pipe 6 to supply water to the second water supply tank 4, so that the first water supply tank 1, after water replenishment, supplies water to the scrubbing device. This ultimately reduces the impact of the water replenishment process on the scrubbing effect of the scrubbing tower.

[0043] Reference Figure 2 and Figure 3 The first water replenishment detection mechanism 7 includes a first water level detection element 71, a first switch trigger element 72, a first water supply switch 73, and a first water replenishment control switch 74. One end of the first water level detection element 71 is arranged facing the first water replenishment cavity 11 and located inside the first water replenishment cavity 11. The middle part of the first water level detection element 71 is hinged to the inner wall of the first water replenishment tank 1. A first control cavity 12 is opened at the hinge point between the first water replenishment tank 1 and the first water level detection element 71. The other end of the first water level detection element 71 is located inside the first control cavity 12. The first switch trigger element 72, the first water supply switch 73, and the first water replenishment control switch 74 are all arranged inside the first control cavity 12. One side of the first switch trigger element 72 is connected to the middle part of the side of the first control cavity 12 facing the first water replenishment cavity 11. The first water supply switch 73 and the first water replenishment switch are both connected to the top of the first water replenishment cavity 11 and are spaced apart from the top of the first switch trigger element 72 by at least the thickness of the first water level detection element 71.

[0044] When the first water replenishment detection mechanism 7 is working, the first water level detection element 71 detects the water level in the first water replenishment tank 1 and feeds back the water level status to the first switch trigger element 72. The first switch trigger element 72 receives the water level signal from the first water level detection element 71. When the water level in the first water replenishment tank 1 is too low, it controls the first water supply switch 73 and the first water replenishment control switch 74 in the first control cavity 12, causing the first water supply pipe 2 to close, the second water supply pipe 5 to open, and the first water replenishment pipe 3 to open and replenish water into the first water replenishment tank 1. When the first water level detection element 71 detects that the water level in the first water replenishment tank 1 is full, the first switch trigger element 72 controls the first water replenishment control switch 74 to close the first water replenishment pipe 3, and the first water replenishment tank 1 stops replenishing water.

[0045] Reference Figure 2 and Figure 3The first control chamber 12 is positioned close to the top of the first water supply chamber 11. A hinge is connected to the wall of the first control chamber 12 facing the first water supply chamber 11. The first water level detection element 71 is connected to the first water supply tank 1 via the hinge. The positioning of the first control chamber 12 close to the top of the first water supply tank 1 reduces the probability of leakage of the first water supply switch 73 and the first water supply control switch 74 inside the first control chamber 12.

[0046] Reference Figure 2 and Figure 3 The first water level detection component 71 includes a first water level float 711, a first pull rope 712, and a first rotating rod 713. The first water level float 711 is installed in the first water supply tank 1. The first water level float 711 is connected to one end of the first pull rope 712. The other end of the first pull rope 712 is connected to one end of the first rotating rod 713. A hinge is connected to the middle of the first rotating rod 713. The other end of the first rotating rod 713 is installed in the first control cavity 12 and connected to the first switch trigger 72.

[0047] The first water level detection element 71 senses the water level in the first water replenishment tank 1 through the first water level float 711. When the water level in the first water replenishment tank 1 is too low and reaches the replenishment water level, the first water level float 711 drives the first pull rope 712 to tighten, thereby giving the first rotating rod 713 a downward rotational force, causing one end of the first rotating rod 713 located in the first control cavity 12 to rotate and abut against the first water supply switch 73 and the first water replenishment control switch 74, so that the first water replenishment tank 1 stops supplying water to the washing device, and the first water replenishment tank 1 starts replenishing water and the second water replenishment tank 4 replenishes water to the washing device.

[0048] Reference Figure 2 and Figure 3 The first switch trigger 72 includes a positioning partition plate 721 and a flexible trigger head 722. One side of the positioning partition plate 721 is fixedly connected to the middle of the cavity wall of the first control cavity 12 opposite to the first rotating rod 713. The positioning partition plate 721 divides the first control cavity 12 into two spaces arranged vertically. The flexible trigger head 722 is fixedly connected to the side of the positioning partition plate 721 facing the first rotating rod 713. The distance between the flexible trigger head 722 and the rotation center of the first rotating rod 713 is less than the length of the first rotating rod 713 located near the rotation center of the first control cavity 12. The first water supply switch 73 and the first water replenishment control switch 74 are both fixedly connected at one end to the top of the first control cavity 12. The distance between the positioning partition plate 721 and the first water supply switch 73 and the first water replenishment control switch 74 is greater than the thickness of the first rotating rod 713.

[0049] The first switch trigger 72 holds one end of the first rotating rod 713 located in the control cavity at one end of the positioning partition plate 721 under normal conditions through the positioning partition plate 721 and the flexible trigger head 722. When the first water level float 711 transmits force to the first rotating rod 713 through the first pull rope 712, the first rotating rod 713 passes over the flexible trigger head 722 and reaches the other end of the positioning partition plate 721 under the force transmitted by the first pull rope 712, thus changing the connection relationship between the first rotating rod 713 and the first water supply switch 73 and the first water replenishment control switch 74.

[0050] The first water replenishment control switch 74 and the first water supply switch 73 are equipped with reset springs. One end of the reset spring is fixedly connected to the cavity wall of the first control cavity 12, and the other end of the reset spring abuts against the end of the first water replenishment control switch 74 and the first water supply switch 73 away from the first control cavity 12.

[0051] The reset spring can restore the first water supply control switch 74 and the first water supply switch 73 to their original positions after the first rotating rod 713 is separated from the first water supply control switch 74 and the first water supply switch 73.

[0052] Reference Figure 2 The second water replenishment detection mechanism 8 includes a second water level detection element 81, a second switch trigger element 82, a second water supply switch 83, and a second water replenishment control switch 84. The side wall of the second water replenishment tank 4 is provided with a second control cavity 42. The structure of the second water level detection element 81 is the same as that of the first water level detection element 71. The structure of the second switch trigger element 82 is the same as that of the first switch trigger element 72. The second water supply switch 83 and the second water replenishment control switch 84 are both fixedly connected to the top of the second control cavity 42.

[0053] The second water replenishment detection mechanism 8 detects and provides feedback on the water level in the second water replenishment tank 4 through the second water level detection component 81, the second switch trigger component 82, the second water supply switch 83, and the second water replenishment control switch 84. The working principle of the second water replenishment detection mechanism 8 is the same as that of the first water replenishment detection mechanism 7.

[0054] Reference Figure 2 and Figure 4The bottom ends of the first water supply tank 1 and the second water supply tank 4 are provided with control grooves 13. A control trigger plate 9 is slidably connected within the control grooves 13. A drive component 10 is connected to one side of the control trigger plate 9. The drive component 10 is electrically connected to the first water supply switch 73 and the second water supply switch 83. The end face of the control trigger plate 9 is provided with a first connecting hole 91 and a second connecting hole 92 penetrating the control trigger plate 9. The distance between the first connecting hole 91 and the second connecting hole 92 is greater than the distance between the first water supply pipe 2 and the second water supply pipe 5 by the length of one diameter of the first water supply pipe 2. In another embodiment, the distance between the first connecting hole 91 and the second connecting hole 92 is less than the distance between the first water supply pipe 2 and the second water supply pipe 5 by the length of one diameter of the first water supply pipe 2.

[0055] The control groove 13 at the bottom of the first water tank 1 and the second water tank 4 allows the control trigger plate 9 to slide. When the drive component 10 drives the control trigger plate 9 to move, it drives the first connecting hole 91 to pass through the first water supply pipe 2 and the second connecting hole 92 to pass through the second water supply pipe 5. When the first connecting hole 91 is not connected to the first water supply pipe 2, the control trigger plate 9 blocks the first water supply pipe 2. When the second connecting hole 92 is not connected to the second water supply pipe 5, the control trigger plate 9 blocks the second water supply pipe 5, thereby realizing the control of the connection device between the first water supply pipe 2 and the second water supply pipe 5.

[0056] Reference Figure 4 The driving component 10 includes a driving motor 101 and a driving gear 102. The driving motor 101 is electrically connected to the first water supply switch 73 and the second water supply switch 83. The driving gear 102 is connected to the output shaft of the driving motor 101. The side wall of the control trigger plate 9 is provided with a driving engagement tooth 93, and the driving gear 102 engages with the driving engagement tooth 93.

[0057] The drive unit 10 drives the drive gear 102 to rotate through the drive motor 101, thereby causing the drive gear 102 to drive the control trigger plate 9 to move within the control slide 13 through the drive meshing teeth 93.

[0058] The implementation principle of the continuous water replenishment device for a gas scrubbing tower according to an embodiment of this application is as follows: During the operation of the gas scrubbing tower, the first water replenishment tank 1 first supplies water to the scrubbing device through the first water supply pipe 2 to meet the working conditions of the scrubbing device. When the water level in the first water replenishment tank 1 drops to the replenishment water level, the first water replenishment detection mechanism 7 controls the first water supply pipe 2 to close and the second water supply pipe 5 to open, allowing the second water replenishment tank 4 to supply water to the scrubbing device to meet the working conditions of the scrubbing device, and controls the first water replenishment pipe 3 to replenish water to the first water replenishment tank 1. When the water level in the second water replenishment tank 4 drops too low to the replenishment water level, the second water replenishment detection mechanism 8 controls the second water supply pipe 5 to close and the first water supply pipe 2 to open, allowing the first water replenishment tank 1, after replenishment, to supply water to the scrubbing device to meet the working requirements of the scrubbing device, and controls the second water replenishment pipe 6 to open and replenish water to the second water replenishment tank 4. This reduces the probability of air bubbles generated during the water replenishment process entering the scrubbing device, ultimately reducing the impact of the water replenishment process on the scrubbing effect of the gas scrubbing tower.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
