Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of rectifying column tray, especially a novel tray bubble cap structure. BACKGROUND

[0002] The rectifying column is a tower type gas-liquid contact device for rectification, and is also a mass transfer and heat transfer device widely used in petroleum and chemical production. The common plate type rectifying column mainly comprises a main tower body, a feed heat exchanger, a tower bottom product heat exchanger, a tower top condenser, a tower top liquid product heat exchanger and a reboiler. The main tower body has a plurality of single-channel bubble cap tray plates arranged in a staggered manner. Each tray plate has a weir flow plate and a plurality of riser pipes. Each riser pipe has a downward cap-shaped bubble cap above it, and the bubble cap does not contact the top and outer wall of the riser pipe. In this way, a gas passage is formed.

[0003] According to the search, the plate tower assembly of the rectifying column disclosed in Patent No. CN218011146U only needs to fix and connect an integrated frame to the tray body by a fixing mechanism when connecting the bubble cap to the top of the riser pipe. At this time, the top of each riser pipe is located in a bubble cap respectively. In this way, the riser pipe and the bubble cap can normally play the role of guiding gas. At the same time, a plurality of long strip-shaped gas dispersion holes are vertically arranged at the bottom of the bubble cap, which can cut and disperse the gas, so that the gas phase can better exchange heat with the liquid phase. At the same time, although the tray body has a plurality of riser pipes and a plurality of bubble caps, only one integrated frame needs to be fixed to the tray body during actual installation and use, which is simple and convenient.

[0004] However, the above-mentioned tray plate structure still has certain defects. The integrated frame is used to fix the bubble cap, and the integrated frame does not have an adjusting structure, so that the spacing between the bubble caps is fixed. When the spacing between the bubble caps needs to be adjusted according to the position of the riser pipe, different sizes of integrated frames need to be replaced, so that many different specifications of integrated frames need to be made, which is high in use and manufacturing cost. In addition, the bubble cap and the integrated frame are fixedly connected, and the entire integrated frame needs to be disassembled and replaced when a single bubble cap is damaged, which is high in replacement cost. Therefore, a novel tray bubble cap structure capable of installing a plurality of bubble caps at one time and adjusting the spacing between the bubble caps is needed to be designed.

It is convenient to individually detach and replace damaged bubble cap cover, and a plurality of bubble cap covers are connected through tension springs, so that the spacing between the bubble cap covers can be adjusted according to the position of the lift pipe on the tower plate body, the bubble cap covers can be increased or reduced to meet different installation requirements, and the installation efficiency of the bubble cap covers is effectively improved by adopting the assembled installation mode.

[0007] According to the novel tower plate bubble cap structure, one side of the tower plate body is fixedly connected with a downcomer, and the height of the downcomer is higher than the height of the tower plate body. In order to prevent liquid backflow

[0008] According to the novel tower plate bubble cap structure, the diameter of the positioning rod is matched with the diameter of the positioning ring. It is convenient to plug and install the bubble cap cover.

[0009] According to the novel tower plate bubble cap structure, the bubble cap cover and the lift pipe are both square, and the lower opening area of the bubble cap cover is greater than the opening area of the lift pipe. It is convenient to form a gas passage.

[0010] According to the novel tower plate bubble cap structure, the inner wall of the upper lift pipe is symmetrically fixedly connected with a connecting rod, and the connecting rod is fixedly connected with the positioning ring. It is convenient to support and fix the positioning ring.

[0011] According to the novel tower plate bubble cap structure, the two ends of the tension spring are in the form of hooks, and the tension spring is detachably connected with the semicircle fixed ring. It is convenient to assemble a plurality of bubble cap covers, and when a single bubble cap cover is damaged, it is also convenient to individually detach and replace, thereby reducing the replacement cost.
