Description
Technical field
The present invention relates to hydrogenation reactor inner member equipment technical field, more specifically a kind of turbine type cold hydrogen box is used
Gas-liquid two-phase in cold hydrogen and pyroreaction logistics are realized in hydrogenation reactor is sufficiently mixed the cold hydrogen box of heat transfer.
Background technology
Hydrogen addition technology is essential major technique during Clean Fuel Production, and hydrogenation reactor is that all kinds of oil add
Nucleus equipment in hydrogen production device.With the exploitation of hydrogenation catalyst as the improvement of hydrogenation technique, the design of hydrogenation reactor is excellent

The performance of hydrogenation technique is determined together.
Hydrogenation reaction belongs to exothermic reaction, it is necessary to control the speed of bed temperature rise by adding cold hydrogen.Cold hydrogen box is to add
One of important inner member in hydrogen reactor, its effect is the low temperature hydrogen and top catalyst bed laminar flow injected by cold hydrogen tube
Under pyroreaction logistics mix rapidly, fully exchange heat, to reduce the temperature of reaction mass, for next bed is provided evenly
Temperature and material are distributed, and give full play to catalyst performance.The quality of cold hydrogen box performance directly influence hydrogenation reaction stability,
The service cycle of catalyst life, product quality and device.
The function of cold hydrogen box mainly has two：1. heat is taken, temperature of charge is controlled；2. mix, the temperature of neutralization reaction material
Difference.The temperature rise of beds is effectively controlled, and reaction mass temperature is reacted no more than the normal temperature in use of catalyst
The radial temperature difference of device is smaller, illustrates that the contact heat transfer of cold hydrogen box is functional.
Chinese patent CN200620133859.0 discloses a kind of spiral-flow type cold hydrogen box, mixed by cold hydrogen tube, baffle plate, semicircle
Road, tangential flow guiding pipe, blending bin and sieve tray etc. is closed to constitute.Its feature is to be additionally arranged to help mixed structure and perforate deflection cone, is made
After cold hydrogen and hot logistics are first pre-mixed within semicircle mixes, then to eddy flow mixing is carried out in blending bin, improve
Contact heat transfer effect between cold hydrogen and hot logistics.But the body shared by the cold hydrogen box is caused due to tangential flow guiding pipe
Product is still larger, and because density contrast easily forms laminar flow during air-liquid two-phase cocurrent, depends merely on extension flow path to heat transfer
Effect increase is not obvious.
Chinese patent CN201220608970.6 discloses a kind of cold hydrogen box, including cold hydrogen distributor, liquid collection tray, mixed
Mould assembling, liquid crude distribution plate and gas-liquid partition tray.The structure makes reaction stream fully be mixed with cold hydrogen using annular hybrid channel
Circumferentially direction flowing after conjunction, and two-stage sieve aperture distribution plate is provided with, mixed reaction stream is fallen with droplet, increased gas
The heat transfer area of liquid two-phase, improves and takes temp effect, pressure drop also very little.But this structure is complex, and fluid is in blending bin
The maldistribution of lower floor.
Chinese patent CN201210408335.8 discloses a kind of chilling hydrogen case, from top to bottom including liquid collecting plate, dropping liquid plate,
Dividing plate and redistribution sieve plate, in the liquid phase that cold hydrogen tube is embedded in collecting tank in the form of the endless tube, cold hydrogen is ejected from cold hydrogen endless tube
To form agitation and bubbling to liquid phase, gas-liquid heat-transfer is strengthened using the larger temperature difference of cold hydrogen and liquid phase；Liquid warp in collecting tank
Fallen in droplets after the dispersion of dropping liquid plate, the contact area of gas-liquid two-phase is improve, so as to chilling hydrogen case greatly improved
Heat exchange efficiency.But the cold hydrogen box residence time of material is shorter, heat exchange inequality is easily caused, and when changing occurs in gas liquid ratio, meeting
There is a series of problem.
In recent years, with the improvement, quickening, the oil refining of oil quality upgrading paces that are hydrocracked with the technique such as hydrodesulfurization
The raising of industry environmental protection requirement, and crude oil heaviness, in poor quality, hydrogen addition technology obtained tremendous development.Reactor diameter
It is increasing, catalyst activity more and more higher, the bed temperature rise of catalyst is up to 20 DEG C.If the performance of cold hydrogen box is not good, reaction
The radial temperature difference of device causes catalyst performance to decline up to 30~40 DEG C, in addition produce temperature runaway phenomenon, cause catalyst failure and
Potential safety hazard.Therefore, new and effective cold hydrogen box is developed extremely urgent.
