FIELD OF THE INVENTION The present invention relates to fluid contacting and dispersing devices and, inter alia, to valve trays for use in fractional columns and other related devices.

That is, the present invention relates to a fixed valve of a distillation column for separating substances on the basis of distillation, absorption, and cooling in petroleum refinery, petrochemical and fine chemistry, washing towers and absorption towers for removing harmful gases or organic substances. The purpose is to be able to produce a large number of fixed valves at a time using a mold, and at the same time to minimize the failure rate, and to simply adjust the height of the valve to the user's requirements.

In general, fractional column trays are initially used with bubble cap trays and sieve trays. Recently, valve trays have been widely used for cost reduction and performance improvement.

The valve tray has a moving type and a fixed type, and the moving type has a wide operating range, but has a disadvantage in that the manufacturing cost is higher than that of the fixed valve because the assembly must be produced by assembling a separate valve.

That is, the above method is designed to allow fluid to pass through the upper part of the tray deck and the moving valve to the upper side of the moving valve, thereby improving performance.

However, the above method has a disadvantage that the manufacturing cost is expensive by manufacturing and then assembling a separate valve after drilling in the tray thanks to the moving type, and also the valve is detached during installation and operation by having to assemble the valve one by one thanks to the tray. As a result, when the valve is largely separated, the performance of the valve and the separated valve are affected, thereby affecting the car device.

In addition, the invention of the present invention forms an opening 8 in the middle of the tray (7), as shown in Figure 5 a, b, the cover plate (9) is formed in the center and several legs (10) between the cover plate and the tray (10). It is supported by using a) but the end portion of the leg is configured to be formed by bending the incision (6) to the inside of the tray.

However, in the above method, the leg of the cover plate is formed by cutting the tray, so that the end of the leg is broken when bending by bending the leg after the leg is cut into the tray.

Summarizing the latter patent, a device for contacting and dispersing a fluid is provided for a fluid contacting column, including a perforated cover plate and a device for positioning and securing the cover plate over the tray hole.

A member to be deflected in each hole of the cover plate is caught so that the fluid can be prevented from hitting the bottom of the tray which is directly raised.

The deflecting member also provides a surface for dispersing the lighter, lighter fluid that passes straight through the hole past the center of the cover plate into the concentrated fluid flowing across the tray in the passage of the cover plate. do.

The cover plate is positioned above the tray hole by being formed integrally with the cover plate and supported by the movable legs which slide into the hole of the tray.

The fluid contacting and dispersing device is designed in the form of a fixed assembly or a movable valve assembly that can be replaced directly by a light fluid.

In the above invention, as shown in FIGS. 4A and 4B, the cover plate 12 is formed to protrude upward from the tray 11, and an opening is formed between the tray and the cover plate, and the tray and the cover plate are formed by several legs 13. ) Is formed integrally.

However, in the above method, when the cover plate is manufactured in the tray, since the leg is directly at an angle of 90 ° of the opening, there is a big problem such that the leg part is broken and a defective product is generated when the leg is actually manufactured.

In addition, in the above method, when the height of the cover plate is to be increased in the tray, the length of the leg portion is constant, and thus the height cannot be adjusted.

The present invention has been invented to solve the above problems, but is formed by integrally forming several legs between the stationary valve and the tray while cutting the upper surface of the valve inward and then bending.                         

The present invention as described above is configured by cutting the leg between the tray and the valve to the inside of the valve, it is easy to adjust the height and prevent the occurrence of defects, the present invention in detail by the accompanying drawings The explanation is as follows.

In a fixed valve formed with a valve in the tray, and is supported by several legs between the valve and the tray,

In the space formed in the tray 1, several legs 2 are respectively configured, but the start of the legs is started in the space, and the valve 3 side forms incisions 4 on both sides from the outside to the inside. Thus, the leg 2 is configured to be bent at the end of the inner cutout of the valve 3, the upper side of the valve is formed by the inclined portion 5 to be inclined downward.

At this time, when the bridge 2 and the space where the meeting portion is formed in a semi-circular shape to bend when forming a strong metal can prevent the leg portion is damaged.

On the other hand, the leg 2 formed in the valve 3 is preferably formed by cutting the length L inwardly from about 55% to 85% from the center of the valve to form the leg portion.

Referring to the operation of the present invention as described above is as follows.

In the tray 1, the valve 3 is configured, but since the end of the valve 3 is bent downward, the flow of fluid is easy, and the leg portion of the valve 3 has an incision 4 formed therein. Since the leg 2 is bent inside the valve 3, it is easy to adjust the height of the valve 3 in the tray 1.

That is, in the present invention, the three legs 2 are arranged close to the upper center of the valve 3, so that the height adjustment of the valve 3 is easy (6-11 mm), and the brittle metal such as titanium or zirconium is strong. In the case of the length of the leg by the incision is also long, it is easy to adjust the height (6-9㎜)

And the present invention can be installed more about 12-15% than the existing products because the bridge supporting the valve is not formed to the outside when installed in the tower interior.

 In addition, in the present invention, since the bridge is formed to the inside of the upper part of the valve, the fluid can pass through the open part, and thus the entire tray can be uniformly gas-liquid contacted, thereby improving the performance of the valve to the best. .

On the other hand, when the valve is made of metal (titanium, etc.) of high strength, the meeting part of the space formed in the leg part and the tray part is formed in a round shape so that there is no angled part when manufacturing the valve, which causes damage during molding. It can be prevented.

That is, since the point where the leg 2, which is bent downwardly inclined at the dead part, meets in the space part of the tray 1 is formed in a circular shape, the leg part can be manufactured without damage even when the metal brittlely formed to be inclined with a valve is formed. By doing so, occurrence of a defect can be minimized.

When both sides of the leg are incised to form the leg 2 in the valve 3, the efficiency is maximized when the leg is formed by cutting about 55% -85% from the outside with its length as the center. You can get a good effect.

On the other hand, since the inclined portion 5 is formed to be inclined downward on the outer side of the upper surface of the valve 3, when the product is used, the rising surface of the gas is maximized by buffing from the bottom surface and dispersing to the outer surface of the valve. The contact efficiency can be maximized.

As described above, in the present invention, several legs are integrally formed between the fixed valve and the tray, and the leg portions of the valve are cut inward and then bent. The structure is simple and easy to manufacture. Because of its long length, it is easy to adjust the height of brittle metals, and the legs supporting the valve are not formed on the outside, so more valves can be installed in the tower tunnel. It is a useful invention that can have a uniform gas-liquid contact with the whole of the valve by passing the fluid through this part is open to form a bridge on the upper surface.

As described above, the present invention has been described in detail only with respect to the described embodiments, but it will be apparent to those skilled in the art that various modifications and variations are possible within the technical spirit of the present invention, and such modifications and modifications belong to the appended claims. will be.
