Abstract
The invention relates to a reforming reaction device. The reforming reaction device comprises reforming reactors, lower hoppers, lifters and upper hoppers, and is characterized in that the reforming reactors are arrayed in a row; each upper hopper is arranged at an obliquely upward position of the corresponding reforming reactor; the upper hoppers are arrayed in a row. By virtue of the reforming reaction device, the heights of frames of the reforming reactors can be greatly reduced, the number of catalyst legs can be greatly decreased, the cost is saved, and equipment such as reactors can be conveniently installed; during maintenance of the reactors, the workload can be reduced, and the maintenance time of the reactors is shortened.
Description
Technical field
The present invention relates to a kind of reforming reaction device, more particularly, to containing reforming reactor, top hopper and catalyst
The PETROLEUM PROCESSING continuous catalytic reforming device of filter.
Background technology
Catalytic reforming unit is the significant process of oil secondary operations, is by a series of specific responses, by low octane rating
Straight-run naphtha the catalytic reaction process that high octane gasoline component and aromatic hydrocarbons are is produced in the presence of catalyst.Reform anti-
The visual plant for answering device to be reformer, is also the core of whole reformer.Reforming reactor typically has 3～4, weight
Whole raw material（Oil gas）Plate type heat exchanger is entered after filter, heating furnace is entered after heat exchange, added to be entered after reaction temperature and reform
Reactor, product sequentially enters heating furnace, reactor, under the separated rear entrance of last reactor product out
One unit.The boosted device of catalyst come from regenerator enters the top hopper on reactor top after being lifted, by from heavy sensation of the body
Power, Jing diplegs enter reforming reactor, and contact of the oil gas with catalyst is realized in reactor.Participate in reacted catalyst to lean on
Self gravitation enters bottom hopper, and lifter catalyst is promoted to the top hopper of next reactor, is carried from last
Rise device catalyst out and be promoted to regenerator, complete the circular regeneration of catalyst.
In prior art, the top hopper in reformer is coaxially arranged with reactor, and top hopper is directly installed on instead
Answer directly over device, increased setting height(from bottom), and make the maintenance lifting of reactor inner member difficult, the top surge tank that need to dismantle, balance
The equipment such as tank, framework platform is of a relatively high.
The content of the invention
The technical problem to be solved in the invention is：For existing reforming reactor and top hopper, bottom hopper, lifted
Device is coaxially arranged, increased setting height(from bottom), and difficulty is lifted when reactor is checked, overhauled, and need to remove equipment component
And framework platform, inspection to reactor, maintenance bring larger difficulty.
To solve the above problems, the technical solution used in the present invention is：A kind of reforming reaction device, includes reforming reaction
Device, bottom hopper, lifter and top hopper, it is characterised in that the arrangement of multiple reforming reactors one is put, and top hopper is located at phase
The oblique upper of reactor, multiple arrangements of top hopper one is answered to put.
Reactor top hopper is changed into " arranged side by side with reactor dislocation by the present invention from current " with reactor centering arrangement "
High position arrangement ", the catalyst dipleg connected between top hopper and reforming reactor was arranged to avoid reaction by former centering
Many of device elbow（10～14）Arrangement can be reduced to 3～6, and there be not any platform on the positive top of reactor, is spacious
Open type.Directly central canal can be hung out inspection, process, return dress from reactor after opening reactor head in maintenance.
Preferably there is catalyst filter in reforming reaction device of the present invention, catalyst filter goes out positioned at reforming reactor
Between mouth and heating furnace, the benefit for increasing filter can be whether the pressure reduction change from before and after filter judges reforming reactor
Leakage catalyst, is preferably preferably between each reforming reactor outlet and heating furnace in multiple reforming reactors and is designed with catalysis
Agent filter.The multiple catalyst filters for being formed can an arrangement put, best filter with the hopper of top it is next arrangement put.
Description of the drawings
Fig. 1 show a kind of reforming reaction device schematic perspective view using the present invention.
Fig. 2 show a kind of reforming reaction device technique schematic flow sheet using the present invention.
In accompanying drawing：
1--- tops hopper 2--- heating furnace 3--- reforming reactors
4--- catalyst filter 5--- bottoms hopper 6--- lifters
7--- tops surge tank 8--- regeneratoies top surge tank 9--- locking hoppers
10--- regenerator A---- oil and gas import B---- oil gas vents
The reforming reaction device of the present invention has the advantages that：1st, reforming reactor framework can be greatly lowered high
Degree, it is cost-effective, it is easy to the installation of the equipment such as reactor；2nd, when reactor is overhauled, it is possible to reduce workload, reactor is shortened
Repair time.
Specific embodiment
Using the reforming reaction device installation diagram shown in Fig. 1, Fig. 2, reformer feed（Oil gas）Enter Jing after raw material filter
Plate type heat exchanger, the oil gas after heat exchange enters heating furnace（2）, add to and enter after reaction temperature reforming reactor（3）, product
Sequentially enter catalyst filter（4）, heating furnace, next reforming reactor, until the product from last reactor out
Next unit is entered after thing is separated.From the boosted device of catalyst that regenerator comes（6）Into reactor top after lifting
Top hopper（1）, by self gravitation, Jing diplegs enter reforming reactor（3）, realize oil gas with catalyst in reactor
Contact.Participate in reacted catalyst and enter bottom hopper by self gravitation（5）, lifter（6）Catalyst is promoted to next
The top hopper of individual reactor（1）, from last lifter（6）Catalyst out is promoted to regenerator top surge tank
（8）, by self gravitation locking hopper is entered（9）Regenerator（10）, after the next catalyst of regenerator is boosted, into top buffering
Tank（7）, top hopper（1）, enter in first reforming reactor by self gravitation, complete the circular regeneration of catalyst.
