Problems solved by technology

[0002] The installation of the existing domestic and foreign tower equipment trays is directly fixed on the inner wall of the tower. The disadvantage is that when the tower body deflects under the action of wind load, the trays from the top of the tower to the bottom of the tower will have different degrees of inclination, thus The gas-liquid phase on the tray is severely unevenly distributed, and the tray near the top of the tower even appears dry liquid, which greatly reduces the separation efficiency of the tray

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] see figure 1 , figure 2 , image 3 , the constant level tray assembly member of the present invention is used for installing the tray 5 in the tray tower 7, and is formed by tailor welding of different materials according to different technological conditions; The arched beam 1 is used to bear the quality of the tray 5 and the process operation medium. For the benefit of bearing, the middle part of the arched beam 1 protrudes upwards, and the two ends are respectively located at the two ends of a certain horizontal diameter in the tower; in order to improve The bearing capacity of the arched beam 1 should be designed according to the different inner diameters of the tower, according to the tangent angle θ of the convex arc in the middle of the arched beam to be 10° to 30°. From figure 1 It can be seen that the upper and lower ends ...

Abstract

The invention belongs to the field of machinery, and particularly relates to a constant horizontal tray combined member suitable for all tray columns in the industries of petrochemical engineering, medicines, food and the like. The technical scheme provided by the invention is that the constant horizontal tray combined member comprises a bow-shaped beam fixedly connected in a column tray tower; the middle of the bow-shaped beam protrudes upward, and two ends of the bow-shaped beam are respectively positioned at two ends of a certain horizontal diameter in the tower; the upper and lower ends of a vertical connecting rod are respectively and movably connected with the center of the lower surface of the bow-shaped beam and the center of the upper surface of the column tray; when a tower body generates large deflection under the effect of wind loads, the connecting rod and the column tray are always mutually perpendicular under the gravity effect. According to the combined member, the tray column can move along with the column body by removing fixed constraint when an original column tray is installed, can swing freely at 360 degrees in space, maintains a constant horizontal state, and can guarantee the best separation efficiency of the column tray under any natural condition and working condition.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a constant level tray combination member suitable for all tray towers in petrochemical, pharmaceutical, food and other industries. Background technique [0002] The installation of the existing domestic and foreign tower equipment trays is directly fixed on the inner wall of the tower. The disadvantage is that when the tower body deflects under the action of wind load, the trays from the top of the tower to the bottom of the tower will have different degrees of inclination, thus As a result, the gas-liquid phase on the tray is seriously unevenly distributed, and the tray near the top of the tower even appears dry liquid, which greatly reduces the separation efficiency of the tray. Contents of the invention [0003] The object of the present invention is to provide a new type of constant-level tray assembly for the above-mentioned defects in the installation of trays in the ...
