In the utility model, described reaction tube is tightly connected by the 2-10 cylindrical section and forms.The height of described cylinder can be the same or different, preferred contour cylinder.
In the utility model, described woven wire can be installed in bottom of cylinder or cylinder top according to actual conditions.The aperture of woven wire is less than the catalyst of filling or the particle diameter of filler, and having at the woven wire center can be by the circular hole of Thermal couple casing pipe.
In the utility model, can adopt the methods such as thread seal connection or flange are connected and sealed between the socket, place sealing ring between the reaction tube.
In the utility model, the reaction tube loam cake adopts flange seal to be connected with reaction tube lower cover and reaction tube or thread seal connects, and places sealing ring between upper and lower covers and the reaction tube.
In the utility model, be covered with charging aperture on the reaction tube, charging aperture is preferably disposed on the middle place of reaction tube loam cake.
In the utility model, the Thermal couple casing pipe that the useful cutting ferrule in reaction tube lower cover center connects, the length of Thermal couple casing pipe is decided according to the height of combination afterreaction pipe.
In the utility model, sealing ring can be selected the withstand voltage materials of corrosion resistant such as white steel or graphite, and reaction tube is selected white steel matter, and the height of reaction tube can be decided with different cylinder heights by the number of selecting cylinder.
Compare with fixed bed reactors used in the existing experimental rig, the multi-stage fixed-bed reacting appliance of a kind of combined type of the present invention has the following advantages:
1, accurately because be test multistage reactor, the personnel operation of can ascending a height, the amount of loading catalyst more easily is guaranteed safe filling under normal conditions;
2, conveniently each section catalyst is taken a sample, such as need in the test temporary transient stop transport to catalyst wherein a certain section take a sample, just can carry out the catalyst dismounting to a certain section reactor targetedly, and other each section reactor need not to tear open, each section catalyst also need not again to load, and the catalyst of original bed can not mix string yet.
3, the woven wire of installing between the cylinder can not only be mentioned supporting role to catalyst and filler, and can play repeatedly the effect of Uniform Dispersion reaction logistics, places the generation of colluding stream and bias current;
4, the multi-stage fixed-bed reactor of combined type of the present utility model dismounting, easy for installation, and can adjust according to actual conditions the height of reactor, the use flexibility that has improved reactor.
5, the multi-stage fixed-bed reactor of combined type of the present utility model can be accurately, objectively the activity stability of catalyst is estimated, evaluation result is suitable for frequent operation, investigates the more scientific experimentation requirement of parameter closer to the commercial Application device.
