Abstract
The invention provides a reactor with an inner supporting structure. The reactor comprises a barrel, material entering and exiting openings arranged on the barrel and the inner supporting structure arranged on the inner wall of the barrel, wherein the inner supporting structure comprises a supporting flange and a supporting rack and the flange surface of the supporting fits the supporting rack and is used for supporting the supporting rack. According to the invention, supporting is realized in the manner that the supporting flange fits the supporting rack through the flange surface of the supporting flange; compared with direct welding of a supporting plate and the inner wall of a barrel of a traditional supporting structure, such a manner has the advantages that strength difference between the supporting flange and the barrel is reduced, local stress concentration between the supporting flange and the inner wall of the reactor is lowered and the supporting flange can bear internal pressure, high temperature and gravitational load at one time, is easy to weld and has low cost; and through usage of the improved inner supporting structure, the reactor can resist corrosion and fatigue and does not crack in operation of the reactor, and has longer service life.
Description
Technical field
The application relates to for the various high-temperature high-voltage reaction device technical fields in petroleum refining and chemical industry, Coal Chemical Industry, chemical fertilizer industry and other various chemical equipment, particularly carries out a kind of reactor with inner supporting structure in the hydrogenation reactor that reacts or desulfurization reactor field by catalyst.
Background technology
The basic structure of chemical reactor as shown in Figure 1, include cylindrical shell, be arranged at the end socket at cylindrical shell two ends and turnover material opening, detect opening and supporting structure, cylindrical shell is made up of steel plate or forging, comprises the pressure vessel inside surfacing applied corrosion resistant lining of support lug (or claiming boss).Usually, oil refining hydrogen reactor, desulfurization reactor and petrochemical reactors or Coal Chemical Industry reactor all need to ensure carrying out smoothly of reaction by catalyst, in order to ensure the uniformity of reacting, the most vertical installation of reactor, the internal supporting structure of supporting catalyst is connected on cylinder inboard wall, by stretching into the thermocouple observing and controlling reaction temperature of catalyst different parts.Because reactor often operates at high temperature under high pressure, or there is circulation repeatedly to operate, external and internal compositions on cylinder can cause the stress deformation between itself and cylindrical shell inharmonious, structure heavy wall place intensity is high, non-lipped cylinder strength is low, both involve and cause very large local stress, are easy to cause cracking in the junction of interior outer member and cylindrical shell, so reactor shell seldom arranges opening-nozzle structure under fluid impurity or the effect of fluctuation operating mode.
Along with the large-scale development of petrochemical plant, the volume of reactor reaches 500m
3above, the total catalyst weight of filling also reaches hundreds of ton.Normally run from top to bottom to control vertical reactor, on cylindrical shell, differing heights place has cold hydrogen inlet, uniform balance distribution is developed rapidly after entering reactor for making hydrogen, at the required installation distributor in corresponding entrance height place, make the catalyst in reactor be split up into several layers like this, every one deck must have and independently supports.Like this, there is following problem in support lug: should bear the stress that catalyst gravitational load causes, and bears the local stress that deformation causes again, and the connecting corner place of support lug upper surface and cylindrical shell often ftractures.If penetration of cracks cylindrical shell wall thickness, the oil leak of band HTHP hydrogen can be blasted in air, and the poisonous impurities such as hydrogen sulfide leak in air can cause human body casualty accident.
Traditional solution ensures support lug and the quality of connection with cylindrical shell thereof in manufacturing, during reactor runs, held stationary operation reduces stress, periodic detection support lug section cylindrical shell in maintenance, finds that namely crackle arranges device reparation of stopping, has a strong impact on safety in production and economic benefit.
But traditional solution cannot meet to be taken into account by requirements such as weight load, interior pressure, high temperature and endurances simultaneously.Therefore, research and develop a kind of inner supporting structure can simultaneously taken into account by weight load, interior pressure, high temperature and fatigue proof reactor, be applied to petrochemical industry reactor, to safety in production and economic benefit, there is important engineering significance.
