Novel rapid cooling hydrogen tank

Abstract

The invention discloses a novel rapid cooling hydrogen tank. The novel rapid cooling hydrogen tank comprises, from the upper part to the lower part, a liquid collecting plate, a liquid dropping plate, a separating plate, and a redistributing sieve plate; a center opening of the liquid collecting plate is provided with a traverse baffle; a center opening of the liquid dropping plate is provided with a liquid collecting groove; a cold hydrogen pipe coiled pipe is arranged in the liquid collecting groove; a center opening of the separating plate is provided with a mixing pipe; the center of the redistributing sieve plate is provided with a diversion cone; and the periphery of the diversion cone is provided with small holes. The novel rapid cooling hydrogen tank is provided with the liquid collecting groove, and the liquid collecting groove is used for collecting liquid phase materials of an upper bed layer; the cold hydrogen pipe is arranged in the liquid phase materials in the liquid collecting groove in a coiled manner, cold hydrogen is sprayed out from the cold hydrogen pipe so as to stir and bubble the liquid phase materials, the relatively high temperature difference of the cold hydrogen and the liquid phase materials is used for enhancing gas-liquid heat transferring, heat is transferred from the liquid phase materials to the cold hydrogen, and then the cold hydrogen is mixed with oil gas for heat transferring, so that heat exchange efficiency of the novel rapid cooling hydrogen tank is increased greatly.

Description

technical field [0001] The invention relates to a gas-liquid fluid mixing heat transfer equipment flowing downwards in a petrochemical process, more specifically, it is used in a fixed-bed hydrogenation reactor in a petroleum processing process to make cold hydrogen and hydrocarbon reactants and heat Quenching hydrogen tank with hydrogen fully mixed. Background technique [0002] Due to the increasingly stringent global environmental protection regulations, the issue of sulfur content in petroleum products has attracted much attention. In response to the problem of reducing sulfur content, major oil companies in the world have made many efforts. Hydrogenation technology is an essential technology in the process of clean fuel production. Therefore, like hydrogenation catalysts and hydrogenation processes, the performance and design of hydrogenation reactor systems have naturally received the same attention from the industry. Internals are an important part of the reactor sy...

Problems solved by technology

Due to the prolonged operation period of the hydrogenation unit, the flow state of the material in the initial stage and the final stage of the reaction changes greatly, and the material needs a certain flow rate to form a rotation. It is not advisable to enhance heat transfer by means of swirling flow; the gas and liquid two-phase flow in parallel Due to the difference in density, it is easy to form stratified flow, and the effect of increasing the heat transfer effect is not obvious by simply extending the flow path.
