Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of valves, in particular to a valve device for a sulfur-containing gas recycling system. BACKGROUND

[0002] In industrial production, sulfur-containing gas is one of the common waste gases. When it is discharged, the sulfur-containing waste gas is recycled through a desulfurization tower system, which can not only avoid environmental pollution, but also recycle sulfur. The desulfurization tower can achieve the effects of dust removal and desulfurization (denitrification) by preparing different dust removal agents. The desulfurization tower has various types such as Venturi type, cyclone plate type, cyclone column type, floating ball type, sieve plate type, and pneumatic emulsification type. The equipment technology is becoming mature, and each has advantages and disadvantages. Enterprises can choose different types according to their needs.

[0003] When the desulfurization tower system is installed in the factory for use, the butterfly valve is one of the indispensable equipment. The butterfly valve is directly related to the operating efficiency, safety and economy of the system. It should be noted that the traditional butterfly valve is directly in contact with the liquid during use, so that the valve plate directly bears the pressure of the liquid, which can easily cause deformation of the valve plate and make it difficult to open and close the valve plate. At the same time, the valve plate of the butterfly valve is soaked in the liquid for a long time, which can easily cause the valve plate to be eroded by the liquid. In addition, as the environmental temperature changes, the temperature of the liquid will also change, which can further exacerbate the damage of the liquid to the valve plate, making the desulfurization system unable to operate stably.

[0065] In summary, the working principle of the valve device for the sulfur-containing gas recycling system provided by the embodiment of the present application is as follows:

[0066] When the valve plate 2 is opened by rotating the switch handle 3, the valve plate 2 extrudes the two follow-up push frames 701, so that the follow-up push frames 701 move on the mounting collar 601, and through the two stretching sleeves 702 extrude the two expansion springs 703 to shrink, so that the follow-up push frames 701 drive the arc-shaped pressure-bearing plate 604 to move, the arc-shaped pressure-bearing plate 604 drives the middle transfer sliding sleeve 602 to move, so that the multiple dispersed liquid inlet holes 603 on the middle transfer sliding sleeve 602 move to the other side of the mounting collar 601, and through the contact of the limiting ring 612 with the mounting collar 601, the position of the middle transfer sliding sleeve 602 is limited, at this time the liquid can enter into the valve body 1 through the multiple dispersed liquid inlet holes 603, and the liquid is filtered through the multiple filter plates 611, effectively reducing the impact force when the liquid flows, and at the same time, through the setting of the arc-shaped pressure-bearing plate 604, the problem that the valve plate 2 is extruded and damaged by the pressure of the liquid can be effectively avoided;

[0067] Further, when the follow-up push frame 701 moves, the push column 705 is driven to move in the mounting bracket 608, at the same time, the push column 705 extrudes the extrusion block 707 to rotate through the threaded drive groove 706, the extrusion block 707 rotates to drive the rotating plate 607 to rotate, so that the rotating plate 607 rotates in the rotating slot 609 through the rotating ring 610, the rotating plate 607 rotates to drive the rotating cleaning brush 605 to rotate, so that the rotating cleaning brush 605 rotates in the rotating limiting slot 606, and then the rotating cleaning brush 605 cleans the multiple filter plates 611 when rotating, ensuring the smoothness of the filter plates 611. In addition, it should be noted that when the middle transfer sliding sleeve 602 continuously moves, since the bristles of the rotating cleaning brush 605 are soft, the movement of the middle transfer sliding sleeve 602 will not be affected; in addition, it should be noted that when the rotating plate 607 rotates, the middle transfer rotating rod 708 is driven to rotate synchronously, the middle 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, avoiding that the impurities in the liquid are deposited to cause the impurities at the bottom side of the liquid inlet auxiliary pipe 4 to block or clog the middle transfer sliding sleeve 602;

[0068] Further, when the valve plate 2 is closed, the two follow-up push frames 701 are no longer extruded, and the follow-up push frames 701 are reset under the resilience of the two opening springs 703, the follow-up push frames 701 move the arc-shaped push plates 808 through the follow-up extrusion frames 803, the arc-shaped push plates 808 move the closing sleeves 807, the closing sleeves 807 move the lifting slide rods 805 in the support bases 804, and the lifting springs 806 are stressed, at the same time, the closing sleeves 807 move away from the liquid discharge holes 802, so that the liquid in the valve body 1 enters the emptying box 801, the liquid in the valve body 1 is prevented from accumulating, the problem that the liquid erodes and damages the valve plate 2 is avoided, and the safety of the valve plate 2 is ensured; in addition, when the liquid level in the emptying box 801 continuously rises, the floating detection plate 809 floats, the floating detection plate 809 drives the blocking support 810 to move, the switch handle 3 is blocked, and workers are reminded to discharge the liquid in the emptying box 801 in time, so that the emptying box 801 can be used again.

[0069] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, and all of them should be covered within the protection scope of the present application.
