Abstract
It is a kind of for the three phase slurry bed gas reactor distributor nozzle that Open Side Down, connect by screw head with distribution grid, air inlet pipe 1, variable diameter pipe-blocking-proof 2, anti-blocking ball 3 and escape pipe 4 form.The structure of distributor advantages of simple not only ensure that gas gas after the gas distributor with nozzle was uniformly distributed in bed, but also can efficiently solve the problem of slurries adverse current leads to blocking.
Description
Technical field
The invention belongs to a kind of nozzles for three phase slurry bed gas reactor distributor.
Background technique
Three-phase (Gu gas-liquid -) paste state bed reactor is widely applied during industrial reaction, for reaction heat
Very big catalytic reaction process can effectively remove reaction heat using three phase slurry bed reactor, realize the isothermal of reactor
Operation, guarantees the normal operation of reactor.In three phase slurry bed reactor, gas distributor is to guarantee gas in bed
The important component of even distribution, and nozzle is the key that the important component.Main problem existing for nozzle used at present is slurries
Adverse current causes to block.
Summary of the invention
The purpose of the invention is to overcome the problems of the above-mentioned prior art and provide it is a kind of simple and reasonable, both
It ensure that gas gas after the gas distributor with nozzle is uniformly distributed in bed, and slurries adverse current can be efficiently solved and led
The problem of causing blocking.
The purpose of the present invention can be achieved through the following technical solutions: one kind is for three phase slurry bed gas reactor point
The nozzle of cloth device, which is characterized in that the nozzle opening is downward, which is made of screw head, anti-blocking ball and air jet pipe.
The screw head is that nozzle head outer ring has screw thread, for being connected with gas distributor.
The anti-blocking ball is stainless steel ball, support masterpiece of the anti-blocking ball by gravity, the motive force of gas and air jet pipe
With.When gas sprays outward, gas push power suffered by anti-blocking ball is greater than the gravity of ball itself and the holding power two of air jet pipe
The resultant force of person, therefore anti-blocking ball shifts another side by gas；When not having gas, anti-blocking ball comes back to lowest order due to gravity
To prevent the adverse current of slurries.
The air jet pipe is the hollow air jet pipe of irregular variable diameter, and upper hollow diameter is less than during lower hollow diameter is less than
Portion chamfers hollow diameters and is equal to anti-blocking bulb diameter.
Detailed description of the invention
Fig. 1 show nozzle mounting plate cross-sectional view.
Fig. 2 show the distribution of nozzle mounting plate top nozzle.
Fig. 3 show the monnolithic case of nozzle.
Fig. 4 show nozzle top view.
Fig. 5 show nozzle along central axes cross section.
Specific embodiment
Example one:
It is dynamic in the entrance of nozzle since gas enters nozzle when device goes into operation, suffered by the anti-blocking ball in nozzle
Gas push power is greater than the resultant force of both the gravity of ball itself and the holding power of air jet pipe, therefore anti-blocking ball is pushed to another side,
Gas, which sprays, enters bed.
Example two:
When device is stopped work, due to there is no gas to enter nozzle, there is no power in the entrance of nozzle, the anti-blocking ball in nozzle
Outlet is blocked because being come back to lowest order by gravity, prevents slurries adverse current into nozzle.
The following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
As shown in Fig. 1~2, a kind of distribution grid of simple designs, (such as Fig. 1) includes gas inlet pipe 1, gas distribution tube 2
With 3, nozzle 4；(such as Fig. 2) gas inlet pipe 1 is located at distribution grid center, has two connected distributor pipes 2, each gas point from center
2 (can be more) gas annular distributor pipes 3 are connected on stringing 2.Gas distribution tube 2 and annular spread pipe 3 are provided with multiple sprays
Mouth, nozzle are located at the lower section of gas distribution tube 2 and annular spread pipe 3.
As seen in figures 3-5, the specific processing method of nozzle is considered in the processing and fabricating of nozzle, design, and (such as Fig. 3) can be by
A piece cylindrical body, one section of processing screw thread 1 are used as upper end of nozzle；(such as Fig. 5) creeps into tracheae from upper end drilling tracheal orifice 1, from lower end
Hole 5, the pipe-blocking-proof hole path 2 for being suitble to anti-blocking ball to move from side face drilling, seal the aperture 4 of side after being finally putting into anti-blocking ball 3.
