Description

Technical Field

[0001] The utility model relates to the technical field of fixed valve tower plates, in particular to a guided circular fixed valve tower plate. Background Art

[0002] Circular fixed valve trays are widely used in the petrochemical industry in the mass transfer processes of distillation, stabilization, absorption, desorption, etc. under pressure, atmospheric pressure, and reduced pressure. The diameter of the fixed valve trays currently used in China ranges from 200 to 6400 mm, and the use effect is good. It works very well for media with good fluidity, but it is not so good for media with poor fluidity.

[0003] The circular fixed valve tower structure mainly includes a tower plate with a circular fixed valve, an overflow weir, a cylinder, etc. There are many holes on the circular fixed valve tower plate, and the two sides of the holes serve as gas phase channels. The heat and mass transfer of the medium is carried out on the upper surface of the fixed valve tower plate. The upper liquid flows to the lower tower plate through the overflow weir, which is the main liquid channel. The overflow weir is mainly to maintain the normal medium height of the tower plate with a circular fixed valve to ensure the normal flow of mass transfer. For media with better fluidity, due to the good fluidity of the medium, the medium can easily flow from high to low on the circular fixed valve tower plate, and the use effect is very good; but for media with poor fluidity, due to the poor fluidity of the medium, it is difficult for the medium to flow from high to low on the circular fixed valve tower plate, and some of the media will even spin on the circular fixed valve tower plate, and the use effect is poor. Utility Model Content

[0004] Aiming at the deficiencies of the prior art, the utility model provides a guiding circular fixed valve tower plate.

[0005] The utility model is realized through the following technical scheme, which provides a guiding circular fixed valve tower plate, comprising a plate body and a plurality of circular fixed valves arranged on the upper end surface of the plate body, wherein the circular fixed valve comprises a stamping protrusion stamped upward from the plate body, the upper end surface of the stamping protrusion is provided with a through hole, a guide plate is fixedly connected to one side of the through hole close to the incoming direction of the medium, and the guide plate and the upper end surface of the stamping protrusion constitute a guide hole facing the flow direction of the medium.

[0006] The through holes in this scheme serve as gas phase channels, and the heat and mass transfer of the medium is carried out on the upper surface of the fixed valve tower plate. The guide holes face the flow direction of the medium, thereby increasing the flow rate of the medium and improving the fluidity of the medium.

[0007] As an optimization, the guide plate is tilted and the angle between the guide plate and the upper end surface of the stamping protrusion is 35 degrees to 65 degrees. In this solution, the guide plate is tilted and the angle between the guide plate and the upper end surface of the stamping protrusion is 35 degrees to 65 degrees, thereby ensuring the guidance of the airflow, thereby ensuring the flow rate of the airflow and guiding the airflow.

[0008] As an optimization, the upper end of the guide plate is provided with a downwardly bent arc guide plate. In this solution, the downwardly bent arc guide plate guides the airflow downward, so that the airflow contacts the medium better.

[0009] As an optimization, the angle between the tangent line of the end of the arc-shaped guide plate and the upper end surface of the stamping protrusion is 25 degrees to 50 degrees. In this solution, the angle of the tangent line of the end of the arc-shaped guide plate is limited to improve the guide effect.

[0010] As an optimization, the through hole is a punching hole formed by punching the guide plate upward. In this solution, the upper end surface of the punching protrusion is punched upward, one end of which is separated from the punching protrusion and the other end is connected, thereby punching the guide plate and the guide hole.

[0011] As an optimization, the upper end surface of the stamping protrusion is a plane, and the upper end surface is inclined to the connecting portion of the plate body and the angle between the upper end surface and the plate body is 25 degrees to 40 degrees. The upper end surface is inclined to the connecting portion of the plate body, so as to facilitate the flow of the medium to this portion.

[0018] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0019] like Figures 1 to 3 As shown, a guiding circular fixed valve tower plate of the utility model comprises a plate body 2 and a plurality of circular fixed valves 1 arranged on the upper end surface of the plate body 2 . The plate body 2 is a flat plate, and the circular fixed valves 1 are arranged in an array on the plate body 2 .

[0020] The circular fixed valve 1 includes a stamping protrusion 11 stamped upward from the plate body 2, the upper end surface of the stamping protrusion 11 is flat and circular, the upper end surface is inclined to the connecting portion of the plate body 2, and the angle between the upper end surface and the plate body 2 is 25 degrees to 40 degrees. The thickness of the stamping protrusion 11 is substantially equal to the thickness of the plate body 2.

[0021] The upper end surface of the punching protrusion 11 is provided with a through hole 12, and a guide plate 13 is fixedly connected to the side of the through hole 12 close to the medium supply direction. The through hole 12 is a punching hole formed by punching the guide plate 13 upward. In other words, by punching upward on the upper end surface of the punching protrusion 11, one end of the punching protrusion 11 is separated from the punching protrusion 11, and the other end remains connected to the punching protrusion 11, the punched plate forms the guide plate 13, and the hole formed after the guide plate 13 is punched out is the guide hole 14.

[0022] like Figure 3 As shown, the sides of the guide plate 13 are straight and parallel to each other, and the end of the guide plate 13 is arc-shaped with a central angle of 180 degrees. That is to say, the through hole 12 is also a long hole.

[0023] The guide plate 13 and the upper end surface of the stamping protrusion 11 form a guide hole 14 facing the flow direction of the medium. Therefore, after the airflow flows through the hole 12 from bottom to top, it is guided in the flow direction of the medium, increasing the flow velocity of the medium.

[0024] The guide plate 13 is tilted and the included angle with the upper end surface of the stamping protrusion 11 is 35 degrees to 65 degrees. Figure 2 As shown, the angle A is 35 degrees to 65 degrees.

[0025] The upper end of the guide plate 13 is provided with a downwardly bent arc guide plate 15, so as to guide the airflow obliquely downward. The angle between the tangent line of the end of the arc guide plate 15 and the upper end surface of the stamping protrusion 11 is 25 degrees to 50 degrees.

[0026] The use of the utility model:

[0027] like Figure 1 As shown, the fixed valve tower plate is arranged inside the cylinder 4, and a plurality of circular fixed valves 1 are provided on the fixed valve tower plate. A through hole 12 is opened on the circular fixed valve 1. The through hole 12 serves as a gas phase channel. The heat and mass transfer of the medium is carried out on the upper surface of the fixed valve tower plate. The upper layer of liquid flows to the lower tower plate through the overflow weir 3. The overflow weir 3 is used to maintain the normal medium height of the fixed valve tower plate to ensure the normal flow of mass transfer.

[0028] The upper end surface of the stamping protrusion 11 is stamped upward, one end of which is separated from the stamping protrusion 11 and the other end is connected, thereby stamping and forming the guide plate 13 and the guide hole 14, and the guide hole 14 faces the flow direction of the medium, thereby increasing the flow rate of the medium.
