Problems solved by technology
Since there is a porous layer on the surface of the tray, it can vaporize and separate relatively volatile components in the liquid phase on the surface of the tray when there is a small temperature difference (0.2-1°C) between the upper and lower sides of the tray. It is mainly aimed at the improvement of the rectification operation tray, and is invalid for the absorption operation

Embodiment
[0025] Example A new type of tray with a microporous bubble hood
[0026] This embodiment discloses a novel tray with a microporous bubble cover, such as Figure 1-3 As shown, it includes a tray 10 and a plurality of micropore bubble covers, and a plurality of installation holes 11 are opened on the tray 10, and each micropore bubble cover is detachably installed on the tray 10 through the corresponding installation holes 11 respectively. , the microporous bubble cover is used to refine the gas into microbubbles and make the microbubbles blow out at an angle to the horizontal direction. The gas is blown out from the side micropores of the microporous bubble cover and the horizontal square at an angle a, a is 0-90°, forming bubbles with the same size as the mesh, which not only increases the liquid disturbance, but also prolongs the contact time. The smaller the mesh, the micro The smaller the bubble, the larger the gas-liquid contact area, and the higher the heat transfer and...

The invention discloses a novel tray with microporous bubble caps. The novel tray includes a tray. The multiple microporous bubble caps for refining gas into microbubbles and blowing the microbubblesat an angle to a horizontal direction are arranged on the try at intervals. The microporous bubble caps include multiple full-mesh bubble caps mounted at a central area of the tray and multiple half-mesh bubble caps which are mounted at an arc-shaped area of the tray and form corners with a center line of an overflow weir, wherein the full-mesh bubble caps mounted at a liquid inlet end are higherthan the full-mesh bubble caps mounted at the overflow weir end. The novel tray with the microporous bubble caps has the characteristics of reducing a liquid level gradient to reduce a non-activated area, making a liquid flow uniform and stable, increasing a gas-liquid contact area, promoting bubbling of the liquid, increasing the disturbance of the liquid when a gas flow passes through the liquidlayer and improving the gas-liquid contact efficiency, is suitable for gas-liquid and liquid-liquid contact mass transfer equipment, and can complete unit operations such as absorption, distillationand heat exchange.
Description
technical field [0001] The invention belongs to the technical field of gas-liquid and liquid-liquid contact mass transfer equipment, and in particular relates to a novel tray with a microporous bubble cover. Background technique [0002] The tower is a gas-liquid, liquid-liquid contact mass transfer equipment widely used in the petroleum, chemical, light industry, and pharmaceutical industries to complete unit operations such as absorption, rectification, and heat exchange. The tray is the most basic and important part, which determines the performance of the tower. According to the structure, it can be divided into bubble cap tray, sieve tray, valve tray, tongue tray and so on. [0003] (1) The bubble cap tray is the earliest industrially used tray, which is mainly composed of a gas riser and a bubble cap. The blister is installed on the top of the air riser, and is mostly circular, and there are many tooth gaps around the bottom of the blister. Its structure is complex,...
