Linear liquid distributor

Abstract

The invention relates to a linear liquid distributor. The distributor mainly comprises a tower wall, a filler, a filler pressing ring, a calandria liquid distributor, an annular collector and a funnel, wherein the filler is arranged in the tower wall; the upper part of the filler is pressed by the filler pressing ring; the filler pressing ring is fixed in the tower wall through bolts; the calandria liquid distributor is placed on the filler pressing ring and combined with the filler pressing ring into a whole body; the upper part of the calandria liquid distributor is sequentially provided with the funnel and the annular collector from the bottom to the top; the annular collector is communicated with the funnel; the lower part of the funnel is provided with a liquid level tube which is communicated with the calandria liquid distributor; and the filler pressing ring is provided with a flow guide plate. The distributor of the invention has the advantages of increasing the anti-block performance, improving the distribution quality of the liquid, increasing the circulation area, and reducing the using amount of the material; and parallel grid plates in the filler pressing ring are heightened to play a certain role in improvement of a flow field of vapor phase in a tower, make the air flow stably flow upwards and improve the distribution of the vapor phase.

Description

technical field [0001] The invention mainly relates to the field of gas-liquid mass transfer equipment, and mainly relates to a line type liquid distributor. Background technique [0002] The liquid distributor is the most important internal part of the tower. A liquid distributor with good distribution performance can provide a uniform initial liquid distribution, weaken the adverse effects of the amplification effect and the end effect, and can further improve the separation efficiency of the packed tower. The liquid distributor can It is divided into several types such as trough type, disc type, riser type and row type. The above three forms of liquid distributors are used in the occasions of high vacuum rectification (small liquid-gas ratio) in fine and small chemical industries because the distribution quality is easily affected by the level of installation, the distribution area is small and the processing is complicated. The limitations of the liquid distributor are ...

AI Technical Summary

Problems solved by technology

However, due to the relatively small liquid gas in the high-vacuum rectification of the traditional pipe-type liquid distributor, in order to achieve the liquid spraying point density required for efficient structured packing, the number of liquid distribution holes is often large, the hole diameter is small, and the holes are opened in the distribution area. The bottom of the liquid pipe is easily blocked by solid particles in the liquid distribution pipe, resulting in uneven distribution of the liquid, resulting in a decrease in the effective wetted area of ​​the filler and the generation of channeling, resulting in a decrease in separation efficiency
