Problems solved by technology

The trays of the current composite bubble-cap towers are mainly connected to the tower body by welding, but due to the large working temperature difference of this type of tower, the expansion coefficient of the lining material is relatively large
And because the tower body is made of composite material and protected by glass fiber reinforced plastics, there will be a large gap between the expansion coefficient of the tower body and the expansion coefficient of the tray, and it is very easy to cause weld cracks under the condition of large temperature difference
Once the weld cracks, the liquid in the upper layer of the tray and the gas in the lower layer of the tray will no longer flow through the exclusive channel, but will be lost from the crack, reducing the contact between liquid and gas, and affecting the working efficiency of the bubble cap column

Embodiment 1

[0033] Such as figure 1 As shown, the present embodiment provides a liquid seal device for the bubble column tray 2, the tray 2 and the liquid seal device are arranged in the tower body 1 of the bubble column, and the liquid seal device includes a support structure 3 and a liquid seal structure 4 . The supporting structure 3 is a supporting ring plate, which is arranged horizontally, and the outer circumference of the supporting ring plate is seamlessly fixedly connected with the inner wall of the tower body 1, preferably by welding. The tray 2 is placed on the supporting ring plate and is not welded with the tower body 1 .

[0034] The liquid seal structure 4 includes a first liquid seal plate 41 and a second liquid seal plate 42 coaxial with the tray 2 and arranged along the circumference of the tray 2, and the second liquid seal plate 42 is arranged on the first Inside the liquid seal plate 41, the upper end of the second liquid seal plate 42 is seamlessly fixedly connect...

Embodiment 2

[0046] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that, in the liquid sealing device of the bubble column tray 2 of this embodiment, the horizontal annular baffle 421 and the vertical annular baffle 422 of the second liquid sealing plate 42 are integrated Formed, the vertical annular baffle 422 is located on the inner peripheral edge of the horizontal annular baffle 421 , and the horizontal annular baffle 421 and the vertical annular baffle 422 smoothly transition to form an arc-shaped second liquid seal plate 42 .

[0047] The second liquid seal plate 42 of this embodiment is integrally formed, has good stability and is easy to install, and forms an arc from top to bottom, and the side of the second liquid seal plate 42 in contact with the liquid has less blocking effect on the flow of liquid , and it is not easy to accumulate residues.

Embodiment 3

[0049] The difference between this embodiment and Embodiment 1 is that, in the liquid seal device of the bubble column tray 2 of this embodiment, the second liquid seal plate 42 is an annular baffle plate arranged obliquely, and faces the tray from top to bottom. The direction of the central axis of 2 gradually shrinks, and the section of the formed liquid seal chamber 43 is approximately triangular. The upper end of the second liquid seal plate 42 is welded to the tower body 1 at the upper end of the first liquid seal plate 41, and the lower end is horizontal and connected to the tray. 2 touch or stick.

[0050] Further, a reinforcement plate parallel to the first liquid seal plate 41 is provided inside the liquid seal chamber 43 , the upper end of the reinforcement plate is welded to the second liquid seal plate 42 , and the lower end of the reinforcement plate is in contact with or closely attached to the tray 2 . In this way, the strength of the second liquid seal plate 42...

Abstract

The invention discloses a liquid seal device of a tower tray of a bubble-cap tower. The tower tray and the liquid seal device are arranged in a tower body of the bubble-cap tower; the liquid seal device comprises a supporting structure and a liquid seal structure; the supporting structure is connected with the tower body seamlessly and fixedly; the tower tray is arranged on the supporting structure; the liquid seal structure is arranged on the tower tray; and the liquid seal structure is provided with a liquid seal chamber for avoiding loss of gas and liquid. The tower tray and the tower body are separated and the liquid seal device is provided, so the liquid and the gas can be prevented from losing from the welded joint of the tower tray and the tower body, the gas and the liquid walk the dedicated channel, contact of the liquid and the gas is effectively enlarged, and the working actual effect of the tower is improved.

Description

technical field [0001] The invention belongs to the field of bubble cap towers, in particular to a liquid seal device for bubble cap tower trays. Background technique [0002] A column in which gas or vapor bubbles through a liquid within the column; especially a tray column (as used in the fractionation of petroleum distillates) in which there are many bubbles on the tray. Therefore, it is also called bubble cap tower and bubble cap tower. The trays of the current composite bubble-cap towers are mainly connected to the tower body by welding, but due to the large working temperature difference of this type of tower, the expansion coefficient of the lining material is relatively large. And because the tower body is made of composite material and protected by glass fiber reinforced plastics, there will be a large gap between the expansion coefficient of the tower body and the expansion coefficient of the tray, and it is very easy to cause weld cracking under the condition of ...
