Preferably, the equal import of the secondary cyclone and primary cyclone bottom.
Preferably, first three-way pipe and the second threeway bottom of the tube are fixedly connected with outlet.
Preferably, it is fixedly connected with import at the top of first three-way pipe and the second three-way pipe.
Preferably, the short tube through reactor shell and extends to outside.
The technique effect and advantage of the utility model：The utility model is by being arranged small end socket and ball valve, when tremie pipe is sent out
It is raw when blocking, when clearing up primary cyclone and two level whirlwind tremie pipe in reactor, reactor release need to only be opened
Ball valve is fastened tup for one with rope, tup is put into whirlwind from ball valve, tup vertically downward, is detached by one cyclonic
Device and secondary cyclone enter in tremie pipe, and by stretching pulling cord back and forth, tup hits the material blocked, by block part
Cleaning, and with when clearing up the blanking blockage of reactor bottom, reactor, which need not replace, be not required to very important person will enter equipment
Catalyst need not be unloaded in internal, reactor, the time for clearing up tremie pipe in reactor can be made to greatly shorten, by original
- the day time shortens to-hour, saves human and material resources, financial resources, short tube stretches out reactor, by be arranged the short tube of setting with
The structure type of small end socket can be effectively relieved in reactor operational process because reason of expanding with heat and contract with cold makes primary cyclone and two
Grade cyclone separator deformation.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model；
