Description
Technical field:
The utility model relates to a kind of anti-block apparatus, and in particular to a kind of fluidized bed charge flow rate anti-block apparatus.
Background technique:
In Melamine Production, since trapping ability of the cyclone separator to dust is limited, catalysis in reactor
Agent has a small amount of run and damages, to guarantee that the urea of catalyst feeds intake load within the scope of the ability to bear of catalyst, it is necessary to periodically mend
Add catalyst.Generally, about 3~10 kilograms of catalyst consumption of melamine permission per ton, therefore 2~3 days mend to fluidized bed
Add 2-3 tons of catalyst.Since catalyst interruption number of days is added, cause to add process fluid blocking every time, it is necessary to largely
Nitrogen blow it is stifled, when pipeline is blown it is logical after, a large amount of silica gel are gone out from pipeline in fluidized bed, cause environmental pollution.If avoiding line clogging,
Stifled nitrogen valve will be blown to be open always, then a large amount of invalid nitrogen enter fluidized bed participation side reaction, and by-product is easy blocking material more
Leg and cause run silica gel loss.
Utility model content:
The prior art is difficult to meet the needs of people, and to solve the above problems, the utility model proposes one
Kind fluidized bed charge flow rate anti-block apparatus.
To achieve the above object, the utility model provides the following technical solutions: a kind of fluidized bed charge flow rate anti-block apparatus,
Tank, fluidized bed, connecting tube are added including catalyst, it is characterised in that: the catalyst adds pot bottom equipped with connecting branch, institute
Connecting branch bottom to be stated to connect with connecting tube, the connecting tube other side is connect with fluidized bed, and connecting tube and connecting branch
Junction is equipped with the nitrogen tube being connected, and the nitrogen tube, which is equipped with, blows stifled ball valve, and described blow locates to be equipped with fixed connect in stifled ball valve
The blind plate connect is equipped with metering hole at the blind plate center.
Preferably, the diameter of the blind plate is 25mm, and the diameter of the metering hole is 3mm.
Preferably, described to blow stifled ball valve for DN25 valve.
Preferably, control valve is equipped in the connecting tube of the connecting branch and fluidized bed side.
Compared with prior art, the utility model has the beneficial effects that
Stifled nitrogen charge flow rate is blown by changing, that is, ensure that and fluidized-bed reaction is not impacted, and improve operation
Environment.Do not increase any practical technology of investment, constructs and easy to operate；Reduce nitrogen usage amount, reduces nitrogen making machine electricity
Consumption；The human and material resources for blowing blocked pipeline are saved；Atmosphere pollution is avoided, operating environment is improved；Implement from after transformation so far, fortune
Row is good, is practical environmental transformation project.
The design operation is simple, and comprehensive practical is strong, use easy to spread.

Specific embodiment:
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Embodiment 1, a kind of fluidized bed charge flow rate anti-block apparatus, including catalyst add tank 5, fluidized bed 1, connecting tube
3, the catalyst adds 5 bottom of tank equipped with connecting branch 4, and 4 bottom of connecting branch is connect with connecting tube 3, the connection
3 other side of pipe is connect with fluidized bed 1, and connecting tube 3 is equipped with the nitrogen tube 7 being connected, the nitrogen with the junction of connecting branch 4
Tracheae 7, which is equipped with, blows stifled ball valve 6, and described blow is located to be equipped with the blind plate 9 being fixedly connected in stifled ball valve 6, is equipped at 9 center of blind plate
Metering hole 8.
The diameter of the blind plate 9 is 25mm, and the diameter of the metering hole 8 is 3mm.
It is described to blow stifled ball valve 6 for DN25 valve.
Control valve 2 is equipped in the connecting tube 3 of 1 side of the connecting branch 4 and fluidized bed.
The utility model makes the blind plate 9 of one piece of ∮ 25, blind when in use for fluidized bed charge flow rate anti-block apparatus
3mm metering hole 8 is beaten at 9 center of plate, this blind plate 9 is inserted after blowing stifled ball valve 6DN25 valve to fluidized bed, and it is normally opened that opening blows stifled ball valve 6,
3 line clogging of connecting tube can be prevented.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
