Gas liquid distributor

Abstract

The invention discloses a gas liquid distributor, which comprises a top cover (1), a center pipe (2), and a connection board (3); the center pipe (2) comprises an inlet part (21), an outlet part (22), and a liquid-falling part (23) located between the inlet part and the outlet part; the top cover is fixed above the inlet part of the center pipe through the connection board; an annular space (4) is formed between the inner wall of the top cover and the outer wall of the inlet part; wherein a plurality of through holes (24) are formed on the liquid-falling part of the center pipe and are distributed along an axis direction of the center pipe. In the gas liquid distributor, the flow directions of the gas phase and the liquid phase is basically perpendicular, and thus better mixing effect is achieved. In addition, when a plurality of distributors with different mounting heights are mounted on a distribution disc, or the distribution disc is inclined or liquid level fluctuation occurs, the plurality of through holes which are distributed on cross sections with different heights along the axis direction of the center pipe can balance the flow distribution among the plurality of distributors, and thus the whole distribution uniformity of the plurality of distributors is improved.

Description

technical field [0001] The present invention relates to a gas-liquid distributor, in particular to a device for mixing and distributing in a gas-liquid two-phase co-current downward flow container, so as to realize the mixing of the gas-liquid two-phase mixed flow and promote the gas-liquid The concentration and temperature between the two phases are uniform, and the gas-liquid mixture flow is evenly distributed on the flow channel with a large cross-sectional area. Background technique [0002] In the field of petroleum processing, the fixed bed trickle flow hydrogenation reactor is widely used in the hydrofinishing of distillate oil, paraffin, lubricating oil, hydrocracking of wax oil and most of the residual oil hydrotreating. In the hydrogenation reactor, the gas-liquid mixture flows side by side through the catalyst bed to react. If the flow distribution at the entrance of the catalyst bed is uneven, the flow of the catalyst bed will form a channel or short circuit, an...

AI Technical Summary

Problems solved by technology

Therefore, in the above-mentioned existing gas-liquid distributor, the flow directions of the gas phase and the liquid phase are basically the same, so the mixing effect between the gas-liquid two phases is not ideal

Moreover, if multiple gas-liquid distributors with different installation heights are installed on the distribution plate, the liquid level of the liquid phase accumulated on the distribution plate may be different, resulting in mutual imbalance between multiple gas-liquid distributors, thereby Causes uneven distribution of multiple gas-liquid distributors

Or when the distribution plate tilts or the liquid level fluctuates, it will also cause uneven distribution of multiple gas-liquid distributors
