Description

TECHNICAL FIELD

[0001] The application relates to the technical field of trays, in particular to a novel anti-blocking efficient tray. BACKGROUND

[0002] The tray is a device for realizing gas-liquid or liquid-liquid mass transfer, and is a core part of unit operations such as distillation columns, absorption columns and extraction columns. The main function is to provide a space for full contact and mass transfer of gas-liquid two phases, and to realize separation and purification of a mixture through differences in physical or chemical properties of different components. There are various types of trays, including a slant-hole tray.

[0003] In the related art, the slant-hole tray is prone to be blocked due to its inclined structure during use. In order to prevent the tray from being blocked, for example, the prior art with the publication number CN209361891U provides an efficient anti-blocking slant-hole tray. The device drives the scraping plate to move around through the push rod to scrape the hole end of the screen hole, thereby avoiding blockage of the screen hole during use and helping to improve the use efficiency of the tray body.

[0004] Although the scraping plate can clean one side of the slant-hole tray and the hole end of the screen hole in the prior art, when the tray is used, the processed materials contain sticky substances, solid particles or components prone to scale formation. These substances are prone to accumulate at the screen hole, which can easily block the inner side of the screen hole. The blockage of the screen hole can reduce the gas-liquid contact area, resulting in a decrease in mass transfer efficiency and affecting the separation effect of the materials in the tower.

[0005] In view of this, a novel anti-blocking efficient tray is provided. CONTENT OF THE UTILITY MODEL
