Along with the progress of hydrogen addition technology, catalyst activity is more and more higher, the diameter of catalytic bed is also increasing, meeting as uneven in heat exchange makes the temperature in beds radial direction there will be very large difference and causes hot-spot, this hot-spot is not if solved, catalyst coking can be caused, not only damage the performance of catalyst, reactor also there will be Biased flow phenomenon, thus greatly reduce the life cycle of catalyst, also induce reaction device operation fluctuation, this is just also more and more higher to the requirement of cold hydrogen box, and the cold hydrogen box used at present, volume ratio is larger, fluid baffling in cold hydrogen box body is few, the time of staying is short, cold hydrogen and hot logistics undercompounding, heat exchange is uneven, therefore its radial temperature difference is larger,
Utility model content
The utility model mainly solve existing cold hydrogen box stop long-pending larger, fluid baffling in cold hydrogen box body is few, the time of staying is short, and cold hydrogen and hot logistics undercompounding, the technical problems such as heat exchange is uneven, and radial temperature difference is larger, provide a kind of cold hydrogen injection dish.This cold hydrogen injection is coiled cold hydrogen and hot logistics and to be mixed fully and heat exchange is even, from the mixed material that this cold hydrogen injection coils out, can be distributed to equably in the working sections of whole reactor, its radial temperature difference is little, what ensure that lower floor reacts carries out smoothly, and the service life of extending catalyst greatly.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of cold hydrogen injection dish, comprise: columnar casing, the end face of described casing is provided with cold hydrogen dish, injection dish is provided with at the middle part of casing, bottom is provided with gas-liquid partition tray, this gas-liquid partition tray is distributed with multiple spiral grooved gas-liquid distributor equably, the center of described cold hydrogen dish is provided with cold hydrogen and material head piece, the below of this cold hydrogen and material head piece is provided with the deflection plate coiled perpendicular to described injection, described deflection plate and cold hydrogen dish and injection dish form mixing chamber, and the position that described injection dish is not surrounded by deflection plate is provided with spray-hole.
Optimize, above-mentioned one cold hydrogen injection dish, described cold hydrogen and material head piece and deflection plate are two and are symmetrical arranged, and described deflection plate is the rectangular configuration being provided with trapeze cut, and the both sides of described deflection plate are provided with two deflectors be parallel to each other.
