A quenching hydrogen tank

Abstract

The invention discloses a novel quenching hydrogen tank. The quenching hydrogen tank consists of a liquid collecting plate, a dripping plate, a partition and a redistribution sieve plate from top to bottom; a baffle tube is provided at the central opening of the liquid collecting plate; The tank is provided with a ring of cold hydrogen pipes; the central opening of the partition is provided with a mixing pipe; the center of the redistribution sieve plate is provided with a diversion cone, and small holes are opened around the diversion cone. The present invention collects the liquid phase of the upper bed layer in the liquid collection tank by setting the liquid collection tank; the cold hydrogen pipe is buried in the liquid phase of the liquid collection tank in the form of a ring pipe, and the cold hydrogen is ejected from the cold hydrogen ring pipe to The liquid phase forms agitation and bubbling, and the large temperature difference between the cold hydrogen and the liquid phase is used to enhance the gas-liquid heat transfer. First, the liquid phase is heated; The heat exchange efficiency of the quenching hydrogen tank is improved.

Description

Technical field [0001] The invention relates to a gas-liquid-fluid mixing heat transfer device that flows downwards in a petrochemical process. More specifically, it is used in a fixed-bed hydrogenation reactor to make cold hydrogen and hydrocarbon reactants interact with heat in a petroleum processing process. A quenched hydrogen tank with fully mixed hydrogen. Background technique [0002] Due to the increasingly strict global environmental regulations, the 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 production of clean fuels. Therefore, like hydrogenation catalysts and hydrogenation processes, the performance and design of hydrogenation reactor systems have naturally attracted the attention of people in the industry. Internal components are an important part of the reactor system. In...

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.
