Description

Easy-to-clean fixed bed hydrogenation reactor equipment Technical Field The utility model relates to the technical field of petroleum refining and chemical equipment, in particular to easy-to-clean fixed bed hydrogenation reactor equipment. Background The fixed bed hydrogenation reactor is used as one of core equipment in the petrochemical industry field, and the fixed bed hydrogenation reactor is used for carrying out hydrogenation reaction with sulfur, nitrogen, oxygen and other impurities in raw materials under the action of a catalyst, so that the quality of oil products is obviously improved, and the increasingly strict environmental protection regulation requirements are met. The equipment is widely applied to key processes of reforming, cracking, hydrofining and the like in oil refineries, and is an indispensable technical means for realizing high-efficiency conversion and clean utilization of crude oil. Along with the continuous increase of global energy demand and the continuous improvement of environmental protection standards, the fixed bed hydrogenation reactor has more remarkable effects in improving the quality of oil products and reducing the emission of pollutants, and has important significance in ensuring the energy safety and promoting the development of green chemical industry due to the stable operation and high efficiency. Therefore, developing a high-efficiency and reliable fixed bed hydrogenation reactor device becomes a key problem to be solved urgently in the petrochemical industry at present. The traditional fixed bed hydrogenation reactor equipment has a plurality of defects in the design and application process, and severely restricts the performance improvement and long-term stable operation. The primary problem is that the difficulty of cleaning and maintenance is that the internal structure of the traditional reactor is complex, key components such as a catalyst bed layer and a distributor are difficult to disassemble, so that sediments such as scale scraps and coke are easy to accumulate in the reactor, the pressure drop of the bed layer is increased, the reaction efficiency is reduced, the problems of catalyst poisoning, deactivation and the like are possibly caused, and the service life of the catalyst is shortened. Secondly, the traditional reactor has the defects in the aspects of tightness, corrosion resistance and thermal stability, is difficult to meet the long-term operation requirements under severe working conditions such as high temperature, high pressure, strong corrosion and the like, and increases the equipment failure rate and the maintenance cost. In addition, conventional designs often ignore concerns about operator safety, such as lack of effective emergency pressure relief devices, overheat protection mechanisms, etc., and pose a potential threat to production safety. These technical bottlenecks not only affect the overall performance of the fixed bed hydrogenation reactor, but also limit the sustainable development of petrochemical industry, so that the development of a fixed bed hydrogenation reactor device easy to clean is urgent, and for this reason we propose a fixed bed hydrogenation reactor device easy to clean.
