Abstract
The utility model relates to a cold hydrogen tank. The cold hydrogen tank comprises a cold hydrogen distributor, a mixing tank and a coarse liquid distribution disc, wherein the cold hydrogen distributor is arranged at the top of hydrogen cooling equipment, a liquid collecting tray is arranged below the cold hydrogen distributor, the mixing tank is arranged below the liquid collecting tray, the coarse liquid distribution disc is arranged below the mixing tank, and a gas-liquid distribution disc is arranged below the coarse liquid distribution disc. According to the cold hydrogen tank, the design is reasonable, the mixing of reactant streams is sufficient, and the temperature distribution is uniform; due to an annular mixing passage, the reactant streams can be sufficiently mixed with cold hydrogen and then flow along the circumferential direction; and due to two-stage screen meshes of the coarse liquid distribution disc and the gas-liquid distribution disc, the mixed reactant streams can be changed into droplets so as to drop off, so that the surface area is increased, the cooling effect is improved, and the pressure drop is small. The cold hydrogen tank has the advantages that the phenomena of the existing cold hydrogen tank that the residence time of the reactant streams is short, the mixing is insufficient, and the cooling is nonuniform are solved, and the deficiencies of the existing cold hydrogen tank can be excellently improved, so that the cold hydrogen tank has good economic and social benefits.
Description
Technical field

Background technology
In recent years, because the demand of domestic market to the high-quality distillate constantly increases, the environmental requirement increasingly stringent, and the heaviness of crude oil, in poor quality, impel oil plant be badly in need of to enlarge the production capacity of hydrogenation plant, and hydrocracking be at present unique can be by the technique of inferior distillate oil production high-quality light ends oil.Reactor is the nucleus equipment of hydrocracking process.In reactor, operated by rotary motion has the beds more than 2, and hydrocracking reaction is that the exothermic reaction exothermic heat of reaction is more, and the bed temperature rise is also high.In order to make catalyst performance stabilised and equipment safety, the temperature rise of beds and reaction temperature must be effectively controlled.Usually inject cold hydrogen between two beds.After the abundant hybrid cooling of cold hydrogen and reactant, then enter next beds and react.Cold hydrogen mixes in cold hydrogen box with product.
The conventional cold hydrogen box of domestic design is mostly fairly simple at present, pressure drop is less, exists the mixing of cold hydrogen and product abundant not, and the phenomenon that the logistics cooling is inhomogeneous has long lasting effect to subsequent reactions, may cause catalyst failure and potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of cold hydrogen box, to improve short, undercompounding of the existing cold hydrogen box mixture time of staying, cooling is inhomogeneous, catalyst member lost efficacy and has the technical problem such as potential safety hazard.
The utility model mainly solves the problems of the technologies described above by following technical proposals: a kind of cold hydrogen box comprises cold hydrogen distributor, blending bin, liquid crude distribution plate; Described cold hydrogen box top is provided with cold hydrogen distributor, is provided with the liquid collection dish below cold hydrogen distributor, is provided with blending bin below the liquid collection dish, is provided with the liquid crude distribution plate below blending bin, is provided with gas-liquid partition tray below the liquid crude distribution plate.
As preferably, described cold hydrogen distributor is dendriform or annular, and cold hydrogen dispenser bottom is provided with nozzle.
As preferably, be symmetrically arranged with spout hole on described liquid collection dish.
As preferably, described blending bin comprises cold hydrogen plate, shell body, inner housing, described cold hydrogen plate is arranged on bottom blending bin, symmetrically on shell body be partitioned into two semicircle hybrid channels, the entrance of hybrid channel is arranged on the blending bin end face, and the outlet of hybrid channel is arranged on the shell wall of inner housing, is provided with the arc deflector perpendicular to cold hydrogen plate near the outlet of hybrid channel, be provided with mounting rail in blending bin, blending bin central authorities are provided with throttle orifice.
As preferably, be provided with sieve aperture on described liquid crude distribution plate and gas-liquid partition tray, the sieve diameter of liquid crude distribution plate is less than the diameter of gas-liquid partition tray sieve aperture.
As preferably, described cold hydrogen distributor, liquid collection dish, blending bin, liquid crude distribution plate, gas-liquid partition tray support by I-beam.
The utlity model has reliable in structure, reasonable in design, the reaction logistics mixes fully, the characteristics of uniformity of temperature profile, mobile by circumferencial direction after adopting the design of annular hybrid channel can make the reaction logistics and cold hydrogen fully mixes, liquid crude distribution plate and gas-liquid partition tray two-stage sieve aperture can make mixed reactant stream become droplet and fall, increase its surface area, improve cooling-down effect, pressure drop is also very little.This utility model has been improved short, undercompounding of the existing cold hydrogen box logistics time of staying, the inhomogeneous phenomenon of cooling, can well suppress to have good good in economic efficiency social benefit because of the inhomogeneous catalyst failure that may cause of temperature drop and potential potential safety hazard.
