Gas liquid distributor with incrustation sediment function

Abstract

The invention discloses a gas-liquid distributor with begrime function. It comprises a chassis, a bell cap, a begrime element and disperse oar. Wherein, said bell cap is mounted above the begrime element via the support element; the begrime element is mounted on the chassis which comprises a inner screen component, a outer screen component, a cover board and a chassis to form the annular space structure; stuffing or protective agent can be filled into annular space according to the demand; the inner cylinder formed by inner screen component is in the hollow cylinder structure; the part of chassis relative to the inner cylinder of inner screen component is on the open structure under which the disperse oar is mounted via the connection element. Compared to present technique, the inventive gas-liquid distributor integrates the functions of begriming and gas-liquid distribution, while ití»s reaction with begriming avoids significantly increase of pressure drop, the influence of begriming function on the gas-liquid distribution. And it can reduce the space of reactor, improve the processing ability of reactor and prolong the working period of activator. The invention can be used in variable gas-liquid fixed-bed reactor in the hydrogenation on the petroleum hydrocarbon.

Description

technical field [0001] The invention relates to a gas-liquid distributor, which belongs to the field of gas-liquid mixing and dispersing equipment, and is suitable for the distribution of gas and liquid under the working condition that the logistics are gas and liquid two-phase coexistence, and the dirt only exists in the liquid phase and the content is small. , especially a device used for gas-liquid distribution and interception, filtration and deposition of impurities, rust and other dirt in the liquid phase before the liquid phase enters the main catalyst bed of the reactor. Background technique [0002] The two phases of gas and liquid are evenly distributed in the hydrogenation reactor, so that the reactants are in good contact with the catalyst, which is the prerequisite for fully exerting the performance of the catalyst and the stable operation of the device. Specifically, since the hydrogenation reaction is an exothermic reaction, in the radial section of the cataly...

Problems solved by technology

Practice has proved that because the fouling baskets are mostly hung on the beams, strung together with chains, and filled with ceramic balls or protective agents around them, not only the installation is cumbersome and the uniformity is poor, but more importantly, the utilization rate of the fouling capacity is not high and the space occupied is relatively large. Big

In addition, since the fouling basket is directly placed on the upper surface of the catalyst bed, the length of the liquid phase flow path varies, which will directly affect the uniform distribution of the liquid phase on the catalyst bed

In addition, after a period of operation, the fouling basket often becomes clogged, causing problems such as an increase in pressure drop, and the above-mentioned fouling basket may also cause uneven gas-liquid distribution due to partial clogging in the late stage of the reaction.
