Description
Technical field
The utility model relates to a kind of key equipment of switching through of natural gas straight system ethylene process, can be applicable to the gas solid catalytic reaction in fields such as chemical industry, petrochemical industry and petroleum refining.
Background technology
Radial reactor is a kind of energy-efficient consersion unit; Have that resistance is little, air speed is big, can use advantage such as catalyst particle, the application of in process units such as chemical industry such as synthetic ammonia, methyl alcohol, styrene, catalytic reforming, petrochemical industry and petroleum refining, having succeeded.
The moving bed radial reactor be a kind ofly can realize that catalytic reaction is carried out continuously, radial reactor that catalysts or adsorbent can be realized cyclic regeneration.Because the activity of this catalyst reactor descends with the prolongation of operating time; Reaction conversion ratio reduces thereupon gradually; Make side reaction increase, if can not catalysts effectively be removed, extreme case even catalyst complete deactivation phenomenon occurs; Can therefore reaction time or the time of staying of catalyst in bed, and catalyst evenly remove from reactor is the key point of moving bed radial reactor.
Summary of the invention
The utility model aims to provide a kind of even moving bed radial reactor; Can satisfy the production requirement of switching through of natural gas straight system ethene under high-speed, the strong heat release condition; Can from reaction bed, remove by equably that activity is lower catalyst, effective adjusting and the control of the catalyst time of staying in the realization response bed take place thereby reduce side reaction; Guarantee that catalyst reactor can be in optimum Working all the time, avoid catalyst in reaction zone inactivation or transition consumption.
The utility model is realized through following technical scheme:
A kind of even moving bed radial reactor, it comprises reactor shell, beds, heat exchanger and central tube; Said reactor shell top is provided with the catalyst charge door, and the bottom is provided with the catalyst discharging opening; Beds top is catalyst storing district; The bottom is the catalyst discharge zone; It is characterized in that: said catalyst discharge zone is provided with catalyst and shifts out structure; This shifts out structure is the marmon clamp nested structure that a bottom and a spacer by reactor shell form, and its spacer upper end is connected in the beds bottom.
The further design of the utility model is that the spacer shape and the reactor shell bottom of shifting out structure are suitable, and the spacer bottom is taper.
The advantage of the utility model and the beneficial effect of generation:
1, catalyst reactor can evenly pass through the reaction zone beds by the gravity effect, guarantees that reaction is continuous, stable, side reaction is few, and product yield is high.
2, the time of staying of catalyst in the reaction zone, can realize controllable operating through the catalyst flow that the reactor bottom outlet draws off.Catalyst in the reactor catalyst bed does not have " dead band " basically.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-catalyst agent storing district; 2-beds; 3-catalyst shifts out structure; The 4-reactor shell; The 5-spacer; A-reacting gas inlet; B-product gas outlet; C-catalyst charge door; D-catalyst discharging opening; E-heat transferring medium import; F-heat transferring medium outlet; α 1, α 2-inclination angle (being not less than the catalyst angle of repose).
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe:
As shown in Figure 1, the even moving bed radial reactor of the utility model design, it comprises reactor shell 4, beds 2, heat exchanger and central tube.Reactor shell 4 tops are provided with catalyst charge door c, and the bottom is provided with catalyst discharging opening d; Reactor shell 4 both sides are respectively equipped with reacting gas inlet a and product gas outlet b.Beds 2 tops are catalyst storing district 1, and the bottom is the catalyst discharge zone, and the catalyst discharge zone is provided with catalyst and shifts out structure 3.
This shifts out structure 3 is marmon clamp nested structures that a bottom and a spacer 5 by reactor shell 4 form, and spacer 5 shapes and reactor shell 4 bottoms are suitable, and promptly spacer 5 tops are cylindric, and it is coniform that the bottom is.Spacer 5 upper ends are connected in beds 2 bottoms; Spacer 5 bottoms are to catalyst discharging opening d top; Form jacket type thus and between housing and shift out structure, deliver to catalyst discharging opening d so that the catalyst that catalytic bed is fallen is concentrated through the chuck that shifts out structure 3, thereby discharging is controlled more easily.
The utility model medium dip angle α 1, α 2 all should be not less than the catalyst angle of repose.The heat transferring medium import e of heat exchanger and heat transferring medium outlet f are like figure.
The structural design of the utility model guaranteeing that reacting gas reliably passes in and out under the condition of reactor, has satisfied the catalyst storing district that catalyst reactor evenly removes simultaneously, and has satisfied bed catalyst charge and bed catalyst.The time of staying of catalyst in reactor, realize through the catalyst flow that the outlet of control reactor bottom draws off.Take place thereby can reduce side reaction, avoid the generation of catalyst in phenomenons such as reaction zone inactivation or transition consumption.
