Carry out the reactor of gas-solid phase reaction process.
At present, the fluidized-bed reactor using in industry includes housing, and air inlet is arranged at the bottom of this housing, and air inlet passes through
Pipeline connects having heaters and blower fan, and gas outlet is arranged at the top of housing, and gas outlet is connected with aggregate tank by communicating pipe.Described shell
Have in horizontally disposed air distribution plate in vivo, be in that fixing seal shape coordinates, between the surrounding of air distribution plate and inner walls on air distribution plate all
It is furnished with fresh air inlet, the housing sidewall above air distribution plate has manhole, manhole has sealing plate.During use, first open sealing plate, will urge
Catalyst particles are sent in housing from manhole；Then, cover sealing plate, start blower fan and heater, by the gas of question response
It is sent in the import of blower fan；Then, the gas of question response sequentially passes through heater, air inlet, fresh air inlet enter into air distribution plate
In the housing of top, gas enters into from fresh air inlet blows out " boiling " state by catalyst granules during the housing above air distribution plate,
In the process, gas is contacted with catalyst and completes to react；Finally, reacted gas enters into through communicating pipe from gas outlet
In aggregate tank.During the course of the reaction, catalyst granules can collide with each other or collide with inner walls, thus producing broken fluid bed
Slag.This fluidized-bed reactor, when using, produces catalyst disintegrating slag and enters directly in aggregate tank with air-flow, in housing
Catalyst slowly tails off so that work efficiency slowly step-down.
Utility model content
Problem to be solved in the utility model is to provide a kind of fluidized-bed reactor, the work efficiency of this fluidized-bed reactor
Higher.
For solving the above problems, provide technical scheme below：
A kind of fluidized-bed reactor of the present utility model includes housing, and air inlet is arranged at the bottom of this housing, and air inlet passes through
Pipeline connects having heaters and blower fan, and gas outlet is arranged at the top of housing, and gas outlet is connected with aggregate tank by communicating pipe.Described shell
Have in horizontally disposed air distribution plate in vivo, be in that fixing seal shape coordinates, between the surrounding of air distribution plate and inner walls on air distribution plate all
It is furnished with fresh air inlet, the housing sidewall above air distribution plate has manhole, manhole has sealing plate.It is characterized in thering is rotation on described communicating pipe
Wind separator, this cyclone separator will be divided into two sections communicating pipe, and communicating pipe, one section one end was connected with gas outlet, the other end and rotation
The import of wind separator is connected, and communicating pipe, another section one end was connected with the gas outlet of cyclone separator, the other end with gather materials
Tank is connected.The solid outlet of described cyclone separator is connected with the housing cavity above air distribution plate by pipeline.
It is to have poly- second on that piece housing medial wall above described air distribution plate to further improvement of the utility model scheme
Alkene layer.The improved advantage of sample is that polyethylene layer can provide cushion effect, thus the shock to inner walls for the catalyst granules can be reduced
Power, extends the service life of housing.
Take above scheme, there is advantages below：
There is cyclone separator due on the communicating pipe of fluidized-bed reactor of the present utility model, this cyclone separator will connect
Pipe is divided into two sections, and communicating pipe, one section one end was connected with gas outlet, and the other end is connected with the import of cyclone separator, and communicating pipe is another
One section one end is connected with the gas outlet of cyclone separator, and the other end is connected with aggregate tank, the solid outlet of cyclone separator
It is connected with the housing cavity above air distribution plate by pipeline.The catalyst disintegrating slag that air-flow carries can be separated using cyclone separator
Out, and be again fed in housing so that the catalytic amount in housing is kept approximately constant, thus ensure that the effect of work
Rate.
Brief description
Fig. 1 is a kind of structural representation of fluidized-bed reactor of the present utility model.
