Description

Technical Field

[0001] This invention relates to the field of valve technology, and in particular to a valve device for a sulfur-containing gas recovery and utilization system. Background Technology

[0002] In industrial production, sulfur-containing gases are a common type of waste gas. When these gases are discharged, a desulfurization tower system is used to recover them, which not only avoids environmental pollution but also recovers the sulfur. Desulfurization towers can achieve both dust removal and desulfurization (denitrification) effects by using different dust removal agents. There are various types of desulfurization towers, including Venturi type, cyclone plate type, cyclone column type, float type, sieve plate type, and pneumatic emulsification type. The technology of these towers is becoming increasingly mature, each with its own advantages and disadvantages. Enterprises can choose different types according to their own needs.

[0003] When a desulfurization tower system is installed and used in a factory, the butterfly valve is an essential piece of equipment, directly affecting the system's operating efficiency, safety, and economy. It should be noted that traditional butterfly valves, during use, are in direct contact with the liquid, causing the valve plate to bear the liquid pressure directly. This can easily lead to valve plate deformation and difficulty in opening and closing the valve. Furthermore, the valve plate is susceptible to corrosion due to prolonged immersion in liquid. In addition, changes in ambient temperature cause fluctuations in the liquid temperature, further exacerbating the damage to the valve plate and preventing the desulfurization system from operating stably. Summary of the Invention

[0004] The purpose of this invention is to provide a valve device for a sulfur-containing gas recovery and utilization system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A valve device for a sulfur-containing gas recovery and utilization system includes a valve body, a valve plate installed inside the valve body, a switch handle for controlling the valve plate installed on the valve body, and an inlet auxiliary pipe and an outlet auxiliary pipe respectively installed on both sides of the valve body. It also includes a dispersion transfer device, which is installed in the liquid inlet auxiliary pipe and the liquid outlet auxiliary pipe. The dispersion transfer device is used to disperse the pressure of the liquid. The dispersion transfer device includes two mounting rings, which are respectively installed in the liquid inlet auxiliary pipe and the liquid outlet auxiliary pipe. A transfer sliding sleeve is provided in the liquid inlet auxiliary pipe. The transfer sliding sleeve is slidably installed in the mounting ring. Multiple dispersion liquid inlet holes are evenly spaced along the circumferential direction on the outer side of the transfer sliding sleeve, and a filter plate is installed in the dispersion liquid inlet holes. An arc-shaped pressure plate is installed on one side of the mounting ring. It also includes a follow-up agitator, which is installed in the liquid inlet auxiliary pipe and the liquid outlet auxiliary pipe. The follow-up agitator is used to agitate the liquid in the liquid inlet auxiliary pipe. The follow-up agitator includes two follow-up pushers, which are respectively movably mounted on two mounting rings. A central rotating rod is rotatably mounted on the arc-shaped pressure plate. An agitating scraper is mounted on the central rotating rod. The central rotating rod is connected to the follow-up pushers in a transmission manner. An active venting device is installed on the liquid inlet auxiliary pipe and the liquid outlet auxiliary pipe. The active venting device is used to vent the liquid on both sides of the valve body. The active venting device includes a venting box, which is connected to the liquid inlet auxiliary pipe and the liquid outlet auxiliary pipe. Both the liquid inlet auxiliary pipe and the liquid outlet auxiliary pipe are provided with a drain hole, and both drain holes are located inside the venting box.

[0006] Furthermore, in a preferred embodiment of the present invention, the dispersion transfer device further includes a rotating cleaning brush, which is located inside the liquid inlet auxiliary pipe; The mounting ring has a rotation limiting groove, and the rotating cleaning brush is rotatably installed in the rotation limiting groove. The rotating cleaning brush is used to clean the multiple filter plates.

[0007] Furthermore, in a preferred embodiment of the present invention, a mounting bracket is mounted on the mounting collar, a rotating plate is rotatably mounted on the mounting bracket, the rotating cleaning brush is mounted on the rotating plate, and the central rotating rod is mounted at the center position of the rotating plate; The mounting bracket has a rotating groove, and a rotating ring is rotatably installed in the rotating groove. The rotating ring is mounted on the rotating plate.

[0008] Furthermore, in a preferred embodiment of the present invention, a limiting ring is installed on the transfer sleeve, the limiting ring being used to limit the position of the transfer sleeve.

[0009] Furthermore, in a preferred embodiment of the present invention, the follow-up stirring device further includes a pushing column, the pushing column being located inside the liquid inlet auxiliary pipe, and the pushing column being mounted on the follow-up pusher; The push column has a threaded drive groove, and the inner wall of the rotating plate is equipped with a pressing push block, which is movably installed in the threaded drive groove.

[0010] Furthermore, in a preferred embodiment of the present invention, a telescopic sliding hole is provided on the transfer rotating rod, and the pushing column is pushed to move within the telescopic sliding hole; The arc-shaped pressure plate has a connecting sliding hole, through which the transfer rotating rod passes.

[0011] Furthermore, in a preferred embodiment of the present invention, two tension sleeves are installed on the follower pusher, and a spreading spring is installed between the tension sleeve and the mounting ring; An outer sheath is installed between the tension sleeve and the mounting ring, and the spreading spring is located inside the outer sheath.

[0012] Furthermore, in a preferred embodiment of the present invention, the active venting device further includes a floating detection plate, which is located inside the venting box; The floating detection plate is equipped with a blocking bracket, which is used to block the switch handle.

[0013] Furthermore, in a preferred embodiment of the present invention, the venting box is provided with two sealing sleeves, which are used to seal the two drain holes; The venting box is equipped with two support bases, and each of the two support bases is movably installed with a lifting slide rod. The lifting slide rod is installed on the sealing sleeve, and a lifting spring connects the lifting slide rod and the support base.

[0014] Furthermore, in a preferred embodiment of the present invention, each of the two follower pushers is equipped with a follower extrusion frame, and each of the two closed sleeves is equipped with an arc-shaped push plate on its top side. The movement of the follower extrusion frame pushes the arc-shaped push plate to move, thereby driving the closed sleeve to move downward.

[0015] The beneficial effects of the valve device for a sulfur-containing gas recovery and utilization system proposed in this invention are: In this invention, by setting up a dispersion transfer device, the pressure of the liquid can be effectively dispersed by the arc-shaped pressure plate, avoiding the problem of the valve plate being directly squeezed by the liquid and damaged by the pressure of the liquid. In addition, when the valve plate is opened by turning the switch handle, the liquid can enter the valve body through multiple dispersion inlet holes and be filtered by multiple filter plates, which can effectively reduce the impact force when the liquid flows. Furthermore, when the transfer sleeve is opened, the rotating plate drives the rotating cleaning brush to rotate, cleaning the multiple filter plates and ensuring that the filter plates are unobstructed.

[0016] Furthermore, in this invention, by setting up a follower agitator, when the follower pusher moves, it drives the push column to move within the mounting bracket. At the same time, the push column squeezes the squeeze push block to rotate through the threaded drive groove. The rotation of the squeeze push block drives the rotating plate to rotate. And when the rotating plate rotates, it synchronously drives the transfer rotating rod to rotate. The transfer rotating rod drives the agitating scraper to rotate, so that the agitating scraper agitates the liquid in the liquid inlet auxiliary pipe, avoiding the deposition of impurities in the liquid, which would cause impurities on the bottom side of the liquid inlet auxiliary pipe to block or clog the transfer sleeve.

[0017] Furthermore, in this invention, by setting up an active venting device, when the valve plate is closed, the two follower pushers are no longer squeezed. At this time, under the rebound force of the two spreading springs, the follower pushers are reset. The follower pushers squeeze the arc-shaped push plate to move through the follower squeezing frame. The movement of the arc-shaped push plate drives the sealing sleeve, thereby causing the sealing sleeve to disengage from the drain hole. The liquid in the valve body enters the venting box, avoiding the problem of liquid accumulation in the valve body and causing liquid to corrode and damage the valve plate, thus ensuring the safety of the valve plate.

[0026] Please refer to the attached instruction manual. Figures 1-12 The present invention provides a valve device for a sulfur-containing gas recovery and utilization system, which includes a valve body 1, a valve plate 2 installed inside the valve body 1, a switch handle 3 for controlling the valve plate 2 installed on the valve body 1, and an inlet auxiliary pipe 4 and an outlet auxiliary pipe 5 respectively installed on both sides of the valve body 1.

[0027] Further, please refer to the appendix to the instruction manual. Figures 3-8 The valve device for a sulfur-containing gas recovery and utilization system provided in this embodiment of the invention also includes a dispersion transfer device 6. The dispersion transfer device 6 is installed in the liquid inlet auxiliary pipe 4 and the liquid outlet auxiliary pipe 5. The dispersion transfer device 6 is used to disperse the pressure of the liquid. Specifically, the dispersion transfer device 6 includes two mounting rings 601, which are respectively installed in the liquid inlet auxiliary pipe 4 and the liquid outlet auxiliary pipe 5. A transfer sliding sleeve 602 is provided in the liquid inlet auxiliary pipe 4. The transfer sliding sleeve 602 is slidably installed in the mounting rings 601. A plurality of dispersion liquid inlet holes 603 are equally spaced along the circumferential direction on the outer side of the transfer sliding sleeve 602. A filter plate 611 is installed in the dispersion liquid inlet holes 603. An arc-shaped pressure plate 604 is installed on one side of the mounting rings 601.

[0028] It should be noted that, in this embodiment of the invention, the arc-shaped pressure plate 604 can effectively prevent the valve plate 2 from being damaged by the pressure of the liquid. When the valve plate 2 is opened by rotating the switch handle 3, the arc-shaped pressure plate 604 causes the transfer sleeve 602 to move, thereby causing the multiple dispersed liquid inlet holes 603 on the transfer sleeve 602 to move to the other side of the mounting ring 601. The liquid enters the valve body 1 through the multiple dispersed liquid inlet holes 603 and is filtered by the multiple filter plates 611, which can effectively reduce the impact force when the liquid flows and ensure the safe use of the valve body 1.

[0029] More specifically, in this embodiment of the invention, a follow-up agitator 7 is also included. The follow-up agitator 7 is installed inside the liquid inlet auxiliary pipe 4 and the liquid outlet auxiliary pipe 5. The follow-up agitator 7 is used to agitate the liquid in the liquid inlet auxiliary pipe 4. The follow-up agitator 7 includes two follow-up pushers 701, which are respectively movably mounted on two mounting rings 601. A transfer rotating rod 708 is rotatably mounted on the arc-shaped pressure plate 604. An agitating scraper 709 is mounted on the transfer rotating rod 708. The transfer rotating rod 708 is connected to the follow-up pushers 701 in a transmission manner. It should be noted that in this embodiment of the invention, when the rotating plate 607 rotates, it synchronously drives the transfer rotating rod 708 to rotate. The transfer rotating rod 708 drives the agitating scraper 709 to rotate, so that the agitating scraper 709 agitates the liquid in the liquid inlet auxiliary pipe 4, avoiding the deposition of impurities in the liquid that could cause impurities on the bottom side of the liquid inlet auxiliary pipe 4 to block or clog the transfer sleeve 602.

[0030] More specifically, in this embodiment of the invention, an active evacuation device 8 is installed on the inlet auxiliary pipe 4 and the outlet auxiliary pipe 5. The active evacuation device 8 is used to drain the liquid on both sides of the valve body 1. The active evacuation device 8 includes an evacuation box 801, which is connected to the inlet auxiliary pipe 4 and the outlet auxiliary pipe 5. Both the inlet auxiliary pipe 4 and the outlet auxiliary pipe 5 are provided with drainage holes 802, and both drainage holes 802 are located inside the evacuation box 801. It should be noted that in this embodiment of the invention, when the valve plate 2 is closed, the two follower pushers 701 are no longer squeezed, causing the sealing sleeve 807 to disengage from the drainage hole 802. This allows the liquid inside the valve body 1 to enter the evacuation box 801, avoiding the problem of liquid accumulation inside the valve body 1 and causing liquid erosion and damage to the valve plate 2, thus ensuring the safety of the valve plate 2.

[0031] Please continue to refer to the instruction manual appendix. Figures 3-8 Furthermore, the valve device for a sulfur-containing gas recovery and utilization system provided in this embodiment of the invention, the decentralized transfer device 6 further includes a rotating cleaning brush 605, which is located inside the liquid inlet auxiliary pipe 4; Furthermore, the mounting ring 601 has a rotation limiting groove 606, and the rotating cleaning brush 605 is rotatably installed within the rotation limiting groove 606. The rotating cleaning brush 605 rotates to clean the multiple filter plates 611. It should be noted that, in this embodiment of the invention, the rotation of the rotating plate 607 drives the rotating cleaning brush 605 to rotate, causing the rotating cleaning brush 605 to rotate within the rotation limiting groove 606, thereby enabling the rotating cleaning brush 605 to clean the multiple filter plates 611 during rotation, ensuring the unobstructed flow of the filter plates 611.

[0032] More specifically, in this embodiment of the invention, a mounting bracket 608 is mounted on the mounting ring 601, a rotating plate 607 is rotatably mounted on the mounting bracket 608, a rotating cleaning brush 605 is mounted on the rotating plate 607, and a central rotating rod 708 is mounted at the center of the rotating plate 607; furthermore, a rotating groove 609 is formed on the mounting bracket 608, and a rotating ring 610 is rotatably mounted in the rotating groove 609, which is mounted on the rotating plate 607. It should be noted that, in this embodiment of the invention, when the rotating plate 607 rotates, the rotating ring 610 rotates within the rotating groove 609, and the rotation of the rotating plate 607 drives the central rotating rod 708 to rotate synchronously. The central rotating rod 708 drives the stirring scraper 709 to rotate, thereby achieving the purpose of stirring the liquid in the liquid inlet auxiliary pipe 4 through the stirring scraper 709.

[0033] More specifically, in this embodiment of the invention, a limiting ring 612 is installed on the transfer sleeve 602, which is used to limit the position of the transfer sleeve 602. It should be noted that, in this embodiment of the invention, when the transfer sleeve 602 moves, the limiting ring 612 is blocked by the mounting ring 601, thereby achieving the purpose of limiting the position of the transfer sleeve 602.

[0034] Please refer to the attached instruction manual. Figures 3-5 and Figures 8-11 Furthermore, in this embodiment of the invention, the follower agitator 7 further includes a pusher column 705, which is located inside the liquid inlet auxiliary pipe 4 and is mounted on the follower pusher frame 701. Additionally, the pusher column 705 has a threaded drive groove 706, and a compression pusher block 707 is mounted on the inner wall of the rotating plate 607, movably mounted within the threaded drive groove 706. It should be noted that in this embodiment of the invention, when the pusher column 705 moves, it compresses the compression pusher block 707 through the threaded drive groove 706, causing the compression pusher block 707 to rotate. The rotation of the compression pusher block 707 drives the rotating plate 607 to rotate, thus achieving the purpose of automatic rotation of the rotating plate 607.

[0035] More specifically, in this embodiment of the invention, the transfer rotating rod 708 is provided with a telescopic sliding hole 710, and the pushing column 705 is pushed to move within the telescopic sliding hole 710; in addition, the arc-shaped pressure plate 604 is provided with a connecting sliding hole 711, through which the transfer rotating rod 708 passes. It should be noted that, in this embodiment of the invention, when the pushing column 705 is pushed, it moves within the telescopic sliding hole 710, and simultaneously, the pushing column 705 drives the transfer rotating rod 708 to rotate, and the transfer rotating rod 708 rotates within the connecting sliding hole 711.

[0036] Please continue to refer to the instruction manual appendix. Figures 3-5 and Figures 8-11 More specifically, in a valve device for a sulfur-containing gas recovery and utilization system provided in this embodiment of the invention, two tension sleeves 702 are installed on a follower pusher 701, and a spreading spring 703 is installed between the tension sleeve 702 and the mounting ring 601; an outer protective sleeve 704 is installed between the tension sleeve 702 and the mounting ring 601, and the spreading spring 703 is located inside the outer protective sleeve 704. It should be noted that in this embodiment of the invention, when the valve plate 2 is opened by rotating the switch handle 3, the valve plate 2 presses against the two follower pushers 701, causing the follower pushers 701 to move on the mounting ring 601, and the two tension sleeves 702 compress the two spreading springs 703 to contract. Furthermore, the outer protective sleeve 704 protects the spreading springs 703, preventing damage to them.

[0037] Further, please refer to the appendix to the instruction manual. Figures 3-5 and Figure 12 The present invention provides a valve device for a sulfur-containing gas recovery and utilization system. The active venting device 8 further includes a floating detection plate 809, which is located inside the venting box 801. Furthermore, a blocking bracket 810 is installed on the floating detection plate 809, which is used to block the switch handle 3. It should be noted that in this embodiment of the invention, when the liquid level in the drain tank 801 continues to rise, the floating detection plate 809 floats upwards. The floating detection plate 809's upward movement causes the blocking bracket 810 to move, blocking the switch handle 3 and thus reminding the worker to promptly drain the liquid from the drain tank 801.

[0038] More specifically, in this embodiment of the invention, the venting box 801 is provided with two sealing sleeves 807, which are used to seal the two drain holes 802. Two support bases 804 are installed inside the venting box 801, and each support base 804 has a movably mounted lifting slide rod 805. The lifting slide rod 805 is mounted on the sealing sleeve 807, and a lifting spring 806 connects the lifting slide rod 805 and the support base 804. It should be noted that in this embodiment of the invention, when the follow-up extrusion frame 803 extrudes the arc-shaped push plate 808, the movement of the arc-shaped push plate 808 drives the sealing sleeve 807, which in turn drives the lifting slide rod 805 to move within the support base 804, causing the lifting spring 806 to be stressed, thus achieving the vertical movement of the sealing sleeve 807 and its disengagement from the drain hole 802.

[0039] Please continue to refer to the instruction manual appendix. Figures 3-5 and Figure 12 More specifically, in this embodiment of the invention, each of the two follower pushers 701 is equipped with a follower squeezing frame 803, and each of the two sealing sleeves 807 has an arc-shaped push plate 808 installed on its top side. The movement of the follower squeezing frame 803 pushes the arc-shaped push plate 808 to move, thereby driving the sealing sleeve 807 to move downward. It should be noted that, in this embodiment of the invention, when the follower pusher 701 is reset, the follower squeezing frame 803 squeezes the arc-shaped push plate 808 to move. The movement of the arc-shaped push plate 808 drives the sealing sleeve 807, causing the sealing sleeve 807 to disengage from the drain hole 802, thereby allowing the liquid in the valve body 1 to enter the emptying box 801, achieving the purpose of automatically emptying the valve body 1.

[0040] In summary, the working principle of the valve device for a sulfur-containing gas recovery and utilization system provided in this embodiment of the invention is as follows: When the valve plate 2 is opened by turning the switch handle 3, the valve plate 2 presses the two follower pushers 701, causing the follower pushers 701 to move on the mounting ring 601. The two tension sleeves 702 press the two spreading springs 703 to contract, causing the follower pushers 701 to drive the arc-shaped pressure plate 604 to move. The arc-shaped pressure plate 604 drives the intermediate sliding sleeve 602 to move, causing the multiple dispersed liquid inlet holes 603 on the intermediate sliding sleeve 602 to move to the other side of the mounting ring 601. The position of the intermediate sliding sleeve 602 is restricted by the contact between the limiting ring 612 and the mounting ring 601. At this time, the liquid can enter the valve body 1 through the multiple dispersed liquid inlet holes 603 and be filtered by the multiple filter plates 611, effectively reducing the impact force when the liquid flows. At the same time, the arc-shaped pressure plate 604 can effectively prevent the valve plate 2 from being damaged by the pressure of the liquid. Furthermore, when the follower pusher 701 moves, it drives the pusher column 705 to move within the mounting bracket 608. Simultaneously, the pusher column 705 squeezes the squeeze pusher block 707 to rotate through the threaded drive groove 706. The rotation of the squeeze pusher block 707 drives the rotating plate 607 to rotate, causing the rotating plate 607 to rotate within the rotating groove 609 via the rotating ring 610. The rotation of the rotating plate 607 drives the rotating cleaning brush 605 to rotate, causing the rotating cleaning brush 605 to rotate within the rotating limiting groove 606. Thus, the rotating cleaning brush 605 cleans the multiple filter plates 611 during rotation, ensuring the unobstructed flow of the filter plates 611. In addition, it should be noted that when the transfer sleeve 602 moves continuously, the bristles of the rotating cleaning brush 605 are soft, so they will not affect the movement of the transfer sleeve 602. Furthermore, it should be noted that when the rotating plate 607 rotates, it synchronously drives the transfer rotating rod 708 to rotate. The transfer rotating rod 708 drives the stirring scraper 709 to rotate, so that the stirring scraper 709 stirs the liquid in the liquid inlet auxiliary pipe 4, preventing impurities in the liquid from accumulating and causing impurities on the bottom side of the liquid inlet auxiliary pipe 4 to block or clog the transfer sleeve 602. Furthermore, when valve plate 2 is closed, the two follower pushers 701 are no longer compressed. At this time, under the rebound force of the two spreading springs 703, the follower pushers 701 are reset. The follower pushers 701 compress the arc-shaped push plate 808 through the follower compression frame 803. The movement of the arc-shaped push plate 808 drives the sealing sleeve 807. The movement of the sealing sleeve 807 drives the lifting slide rod 805 to move within the support base 804, and causes the lifting spring 806 to be stressed. At the same time, the sealing sleeve 807 disengages during movement. The drain hole 802 allows liquid in the valve body 1 to enter the drain box 801, preventing liquid accumulation in the valve body 1 and thus avoiding liquid corrosion and damage to the valve plate 2, ensuring the safety of the valve plate 2. In addition, when the liquid level in the drain box 801 continues to rise, the floating detection plate 809 floats up. The floating detection plate 809 floats up and drives the blocking bracket 810 to move, blocking the switch handle 3 and reminding the worker to drain the liquid in the drain box 801 in time so that the drain box 801 can be reused.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
