Description

Technical Field

[0001] The utility model relates to the technical field of floating valve tower plates, in particular to an anti-corrosion high-efficiency floating valve. Background Art

[0002] The floating valve tray is a commonly used packing support and liquid distribution device. It has many square or circular holes on the tray, and each hole is equipped with a valve plate. The gas pushes the valve plate upward through the valve hole and shoots out horizontally. When passing through the liquid layer, the gas and liquid phases form a foam state to transfer heat and mass. Since the valve plate opening can change with the gas speed, the valve plate can be automatically closed under the action of gravity at low gas speed. Therefore, it has the advantages of high efficiency and high elasticity; and it has a simple structure, low cost and high processing capacity.

[0003] According to a floating valve tower plate disclosed in Chinese patent number CN 212881107 U, it includes a tower plate and a floating valve, and a mounting hole is provided on the tower plate. The floating valve includes a valve body and a valve cover arranged on the top of the valve body, and the valve cover is provided with a tongue hole. The valve body is a trapezoidal platform, and a plurality of air-lifting holes are provided on both sides of the valve body. Limit plates are provided at both ends of the bottom of the valve body; the mounting hole on the tower plate is a rectangle that matches the valve body. The valve body of the utility model is a trapezoidal platform, and the space becomes smaller as it goes up, resulting in a higher gas phase flow rate. The gas phase enters the liquid phase at a higher flow rate, and the injection distance in the liquid phase is large, so that the gas and liquid phases are fully in contact, achieving an ideal effect. Thereby improving product quality, increasing processing volume, and obtaining good economic benefits.

[0004] The tower plate in the prior art can effectively disperse the airflow and promote full contact between gas and liquid, but the following problems may exist during actual use: 1. The size of the liquid outlet of the float valve cannot be automatically adjusted, resulting in the inability of gas and liquid to quickly and fully contact according to actual needs. Secondly, the inside of the float valve is easily corroded, so a corrosion-resistant and high-efficiency float valve is needed to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problems in the prior art that the size of the float valve liquid outlet cannot be automatically adjusted, resulting in the inability of gas and liquid to quickly and fully contact according to actual needs, and secondly, the interior of the float valve is easily corroded, and proposes a corrosion-resistant and high-efficiency float valve.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a corrosion-resistant and high-efficiency float valve, including a tower plate and a power connection plate, a filter element plate is clamped inside the tower plate, filter holes are opened on the top of the filter element plate, a valve seat is provided in an annular array at the top of the tower plate, and a power plug is provided in an annular array at the bottom of the power connection plate, and the positions of the power plug and the valve seat are adapted to each other.

[0007] Preferably, both ends of the valve seat are penetrated by connecting plugs, and the valve seat and the tower plate are bolted together via the connecting plugs.

[0008] Preferably, the interior of the valve seat is hollow, a sleeve is welded on the top of the valve seat, arc-shaped liquid outlet grooves are provided on the front and back sides of the sleeve, and there are two groups of arc-shaped liquid outlet grooves in the same direction.

[0009] Preferably, slides are embedded on both sides of the sleeve, a cover cap is slidably connected to the outside of the sleeve, sliding grooves are opened on both sides of the cover cap, the sliding grooves and slides are adapted to each other, and a limit block is embedded at the bottom of the sliding groove.

[0010] Preferably, a top column is embedded inside the cap, and a top head is clamped at the bottom of the top column.

[0011] Preferably, the front and back sides of the cap are both embedded with bayonet holes, a scraper blade is snapped onto the surface of the bayonet hole, and the surface of the scraper blade is provided with grinding patterns.

[0012] Preferably, a power plug hole is provided on the top of the cap, and the bottom of the power plug and the power plug hole are adapted to each other.

[0013] Beneficial Effects

[0014] In the utility model, a plug-in hole is provided on the top of the cap, and the bottom of the power plug and the plug-in hole are adapted to each other. In the device, there are mainly two anti-corrosion methods, namely surface treatment and cathodic protection. The first is cathodic protection, in which the bottom end of the power plug is inserted into the plug-in hole corresponding to the bottom end, and the power plug is externally powered. By applying an external current, the float valve becomes the cathode of the corrosion battery, thereby preventing corrosion from occurring. At the same time, the power connection plate can store electrical energy transmitted from the outside.

[0015] In the utility model, when the liquid level in the tower rises, the cap will be pushed up by pushing the top head. When the cap is pushed up, it will slide up along the sliding groove. The limit block at the bottom of the sliding groove can play a limiting role to prevent the cap from falling when it slides up. At the same time, in the process of the cap sliding up, the arc-shaped liquid outlet groove will be exposed, and the internal liquid will overflow from it. The more internal liquid, the higher the cap will be pushed up, and the more arc-shaped liquid outlet grooves will be exposed. At the same time, in the process of the cap sliding up and down in a cycle, the scraper will rub the inside of the cap through the grinding pattern to remove dirt and impurities on the surface, prevent the surface from sticking to the surface and corroding the inside of the cap, and at the same time improve the surface flatness and roughness, and solve the problem that the size of the float valve outlet cannot be automatically adjusted in the prior art, resulting in the inability of gas and liquid to quickly and fully contact according to actual needs, and secondly, the inside of the float valve is easily corroded.

The positions of the electrical plug 5 and the valve seat 4 are adapted to each other. When the liquid at the bottom of the tower tray 1 rises, it will be filtered by the filter element plate 2. There are multiple groups of valve seats 4 in the top array of the tower tray 1, and the valve seats 4 on each group of the tower tray 1 can be opened automatically.

[0030] A power plug hole 8 is provided on the top of the cap 9, and the bottom of the power plug 5 and the power plug hole 8 are adapted to each other. In this device, there are mainly two anti-corrosion methods, namely surface treatment and cathodic protection. The first is cathodic protection, in which the bottom end of the power plug 5 is inserted into the power plug hole 8 corresponding to the bottom end, and the power plug 5 is externally powered. By applying external current, the float valve becomes the cathode of the corrosion battery, thereby preventing corrosion. At the same time, the power connection plate 6 can store electrical energy transmitted from the outside. Specific embodiment 2:

The front and back sides of the sleeve 10 are provided with arc-shaped liquid outlet grooves 12. There are two groups of arc-shaped liquid outlet grooves 12 in the same direction. The liquid rising from the bottom of the tower will overflow from the arc-shaped liquid outlet grooves 12, and then the vapor and liquid will come into contact.

[0033] Slides 11 are embedded on both sides of the sleeve 10, and the outer part of the sleeve 10 is slidably connected to the cover cap 9. Sliding grooves 13 are opened on both sides of the cover cap 9.

The surface of the scraper blade 16 is provided with grinding patterns 17 , and the grinding patterns on the scraper blade 16 are granular.

[0036] When the liquid level in the tower rises, the cap 9 will be pushed up by pushing the top 14. When the cap 9 is pushed up, it will slide up along the sliding groove 13. The limit block 19 at the bottom of the sliding groove 13 can play a limiting role to prevent the cap 9 from falling when sliding up. At the same time, when the cap 9 slides upward, the arc-shaped liquid outlet groove 12 will be exposed, and the internal liquid will overflow from it. The more internal liquid, the higher the cap 9 will be pushed up, and the more arc-shaped liquid outlet grooves 12 will be exposed.

[0038] In summary:

[0039] 1. A plug-in hole 8 is provided on the top of the cap 9. The bottom of the power plug 5 and the plug-in hole 8 are adapted to each other. In the present device, there are two main anti-corrosion methods, namely surface treatment and cathodic protection. The first is cathodic protection. The bottom end of the power plug 5 is inserted into the plug-in hole 8 corresponding to the bottom end. The power plug 5 is externally powered. By applying an external current, the float valve becomes the cathode of the corrosion battery, thereby preventing corrosion. At the same time, the power connection plate 6 can store electrical energy transmitted from the outside.

[0040] 2. When the liquid level in the tower rises, the cap 9 will be pushed up by pushing the top 14. When the cap 9 is pushed up, it will slide up along the sliding groove 13. The limit block 19 at the bottom of the sliding groove 13 can play a limiting role to prevent the cap 9 from falling when sliding up. At the same time, when the cap 9 slides upward, the arc-shaped liquid outlet groove 12 will be exposed, and the internal liquid will overflow from it. The more internal liquid, the higher the cap 9 will be pushed up, and the more arc-shaped liquid outlet grooves 12 will be exposed.

[0041] At the same time, when the cap 9 slides up and down in a cycle, the scraper 16 will rub the inside of the cap 9 through the wear pattern 17 to remove dirt and impurities on the surface, prevent them from sticking to the surface and corroding the inside of the cap 9, and at the same time improve the surface flatness and roughness.
