Description

TECHNICAL FIELD

[0001] The utility model belongs to physical separation operation device technical field, especially, relate to a fixed valve tray. BACKGROUND

[0002] The fixed valve tray is also called fixed valve tray, which is one of the trays and is used for mass transfer and separation of liquid and gas. The fixed valve covers the gas phase channel on the tray plate and is supported to a certain height, separating the gas and liquid, so as to achieve the purpose of mass transfer and separation. In the fixed valve tray, the gas flow speed is fast, and when the gas flow passes through the plug hole on the fixed valve tray, the kinetic energy of the gas flow is converted into pressure energy, which sprays the liquid onto the tray above the plug hole, forming liquid droplets. The liquid droplets and the gas pass through the tray in opposite directions and are separated, and the liquid accumulates on the tray and then flows out through the plug hole.

[0003] However, the fixed valve in the prior art is directly stamped from the tray body, which is limited by the material properties. The tray itself is usually made of steel, and the lifting height, i.e. the distance between the upper end of the fixed valve and the tray, is greatly limited, otherwise it is easy to cause metal tensile fracture. Therefore, the application field is limited.

[0004] For example, a high-efficiency large-flux fixed valve tray is disclosed in a Chinese invention patent application [application number: CN02155028.X]. The application comprises a tray, a fixed valve and a downcomer. The fixed valve is directly stamped from the tray body, and the fixed valve is composed of a fixed valve face, a liquid-inlet valve leg and a liquid-outlet valve leg. The fixed valve face is connected to the tray through the liquid-inlet valve leg and the liquid-outlet valve leg. The fixed valve face has a downward-bent fixed valve fold edge, and the angle α of the downward-bent fixed valve fold edge is 10°-60°. The fixed valve fold edge is 3-10 mm away from the tray surface. The fixed valve face is circular, rectangular or trapezoidal. When the fixed valve face is circular, its diameter is 15-60 mm. The liquid-inlet valve leg and the liquid-outlet valve leg are on the diameter line of the fixed valve face, which is perpendicular to the downcomer of the tray. The width of the liquid-inlet valve leg is greater than or equal to that of the liquid-outlet valve leg. When the fixed valve face is rectangular or trapezoidal, the length of the fixed valve face is 20-80 mm, and the width is 10-40 mm. The liquid-inlet valve leg and the liquid-outlet valve leg are on the center line of the fixed valve face, which is perpendicular to the downcomer of the tray. The width of the liquid-inlet valve leg is greater than or equal to that of the liquid-outlet valve leg.

[0026] The utility model will be further explained in detail in combination with the drawings and specific embodiments.

[0027] In combination with Figure 1 and Figure 2 shown, a fixed valve tray, comprising a tray 1, the tray 1 is provided with a plurality of medium holes 2 penetrating the tray 1, and a plurality of fixed valves 3 are detachably connected to the tray 1, the fixed valve 3 covers the upper side of the medium hole 2, and the fixed valve 3 and the medium hole 2 are one-to-one correspondingly arranged.

[0028] In the present invention, when in use, the fixed valve 3 is machined as a separate component to the desired lifting height and then detachably connected to the tray 1. Therefore, the fixed valve 3 of the present invention is a separate component that is detachably connected to the tray 1. The lifting height of the fixed valve 3 is not limited by the material of the tray 1 and can be designed as needed. Furthermore, the detachable connection allows for timely replacement of the fixed valve 3 in the event of natural wear and tear, thereby avoiding affecting the overall performance of the tray 1 or causing the entire tray 1 to be scrapped.

[0029] Combine Figures 2-4 As shown, the fixed valve 3 includes a panel 31, a supporting leg 32 and a fixed leg 33. The panel 31 is located directly above the medium hole 2. One end of the supporting leg 32 is connected to the bottom surface of the panel 31, and the other end extends to the bottom surface of the tower plate 1 through the through hole 4 opened on the tower plate 1 and is connected to the fixed leg 33. The upper surface of the fixed leg 33 is in contact with the bottom surface of the tower plate 1.

[0030] The final lifting height of the fixed valve 3 is determined by the length and tilt angle of the support leg 32 , and the length and tilt angle of the support leg 32 have a large selection range, so that the lifting height also has a large value range.

[0031] Preferably, the panel 31 is circular and the diameter of the panel 31 is larger than the diameter of the medium hole 2. This ensures that the panel 31 can completely cover the medium hole 2.

[0033] The fixing leg 33 is detachably connected to the supporting leg 32 through the cooperation of the clamping block 34 and the clamping groove 35, making the overall installation of the fixed valve 3 simpler and more convenient.

[0034] like Figure 2As shown, the bottom surface of the panel 31 is further provided with connecting grooves 36 matched with the supporting legs 32, and the ends of the supporting legs 32 away from the fixed legs 33 extend into the connecting grooves 36. The connecting grooves 36 are parallel to each other, and a plurality of the connecting grooves 36 are arranged along the radial direction of the panel 31, and the distance between two adjacent connecting grooves 36 is equal. The panel 31 is provided with a plurality of connecting grooves 36 distributed along the radial direction and matched with the ends of the supporting legs 32, and the supporting legs 32 can be connected with different connecting grooves 36 to make the panel 31 have different lifting heights, so that the change of the lifting height can be realized by only replacing the supporting legs 32 with different lengths, thereby reducing the cost.

[0035] As shown in Figure 2 The supporting legs 32 are provided with two and are symmetrically arranged along the axis of the panel 31, and the fixed legs 33 are connected with the supporting legs 32 one by one. In this way, the stability of the support during use can be ensured.

The lower surface of the limiting part 37 is pressed on the upper surface of the tower plate 1, and the lower surface of the limiting part 37 is parallel to the upper surface of the panel 31. The limiting part 37 can limit the downward movement of the fixed valve 3 as a whole, and the fixed leg 33 can limit the upward movement of the fixed valve 3 as a whole, so that the stability of the position of the fixed valve 3 in the vertical direction is ensured by the cooperation of the two.
