Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reactors, in particular to an upflow liquid hydrogenation conversion reactor. Background Art
[0002] An upflow liquid hydrogenation conversion reactor is a device with important applications in the chemical industry, especially in liquid reactions that require hydrogenation conversion. This reactor adopts an upflow design so that the reactant flow flows from bottom to top, thereby bringing a series of unique advantages. The upflow liquid hydrogenation conversion reactor has good adaptability to high-metal inferior raw materials. Since the reactant flow flows from bottom to top, the residence time of the raw materials in the reactor is relatively long, which is conducive to fully carrying out the hydrogenation conversion reaction. At the same time, this design can also effectively reduce the pressure loss in the reactor and improve the overall operating efficiency of the equipment. The upflow liquid hydrogenation conversion reactor has a high space utilization rate. Since the flow direction of the reactants is opposite to the gravity direction, the mass transfer and heat transfer effects inside the reactor are improved, which is conducive to accelerating the reaction speed and improving the conversion rate. In addition, the spatial layout inside the reactor is more reasonable, which can accommodate more catalyst beds and further improve the processing capacity of the equipment.
[0003] In the operation process of the existing reactor, the mixed gas generally has a large flow rate and is concentrated in the center of the reactor cross section and directly rushes onto the distribution plate, which can easily damage the portion of the distributor corresponding to the gas inlet, rendering the entire distributor unusable. The distributor needs to be replaced frequently, which not only increases production costs but also delays the desulfurization process, that is, reduces work efficiency. In addition, the mixed gas in the reactor cannot fully and quickly contact the catalyst, resulting in a low reaction rate. For this reason, we propose an upflow liquid hydrogenation conversion reactor. Utility Model Content
