Technical field
The utility model belongs to petrochemical industry, fluidizing apparatus technical field, particularly a kind of catalyst regenerator.
background technology
Existing block form catalytic cracking unit spent agent enters fluid bed from the side, and most devices do not have spent agent distributor (minority device is provided with simple and easy distributor), and regenerative agent is all to draw from a certain quadrant in Huo Cong bottom, regenerator side.Thisly enter, lead-out mode causes spent agent in fluid bed burning process inhomogeneities.This inhomogeneous following problem that causes: it is long that the catalyst having burns the time, and regenerative agent carbon containing is just low, regenerative agent is active just high; And that some catalyst burn the time is short, regenerative agent carbon containing is just high, and regenerative agent activity is just low.After entering reactor, above-mentioned catalyst directly affects reaction selectivity and conversion ratio.Therefore by spent agent in fluid bed top distributed uniform, and make spent agent burn time consistency at fluid bed, make regenerative agent carbon containing consistent, regenerative agent is active consistent, is the target that regenerator and fluid bed are pursued.
summary of the invention
The purpose of this utility model is to provide a kind of catalyst regenerator, can realize spent agent and burn time consistency at fluid bed, and regenerative agent carbon containing is consistent, the active consistent target of regenerative agent.
The utility model solves the technical scheme that its technical problem adopts: comprise regenerator housing, fluid bed, spent agent feed pipe, regenerative agent carrier pipe, distributor pipe of cardinal wind, it is characterized in that: on fluid bed top, spent agent distributor is set, in fluid bed lower central position, regenerative agent center fairlead is set, fairlead bottom, center is connected with regenerative agent carrier pipe, and Bing center fairlead arranges heat removing tube.
Further, center fairlead is straight tube structure or variable-diameter structure, and upper end can also arrange horn mouth, and bottom can also arrange fluidizing agent distributor.
Further, heat removing tube is single form or band bobbin carriage form, and heat removing tube stretches into fairlead inside, center or stretch into from the side center fairlead inner from bottom.
Further, spent agent feed pipe is directly to stretch into spent agent distributor and be connected from regenerator side; Or be connected with spent agent distributor through spent agent riser, spent agent riser is to enter regenerator or enter separately regenerator through center fairlead.
Further, in fluid bed, grid can also be set.
Further, spent agent distributor is tubular type or slot type.
The utility model innovative point and good effect are:
The utility model innovative point is: on fluid bed top, spent agent distributor is set, in fluid bed lower central position, regenerative agent center fairlead is set, fairlead bottom, center is connected with regenerative agent carrier pipe, and Bing center fairlead arranges heat removing tube.
The utility model good effect is: can realize spent agent and burn time consistency at fluid bed, regenerative agent carbon containing is consistent, and regenerative agent is active consistent, and reduces regenerative agent temperature and improve device oil ratio.
