Abstract
The utility model relates to a catalyst recycling recovery system which comprises a pressure reactor and a storage tank. The storage tank is communicated with the pressure reactor through a material discharging pipe, and an inlet of the material discharging pipe is inserted to the lower portion of the pressure reactor. The catalyst is characterized by further comprising a buffer tank which is connected on the material discharging pipe in series, a material feeding back pipe is arranged at the bottom of the buffer tank, and the material feeding back pipe is communicated with a material pipe of the pressure reactor. The buffer tank is arranged on the material discharging pipe to be used to precipitate catalysts, and the catalysts are prevented from entering into a next working process after entering into the storage tank. After the catalysts are precipitated by the buffer tank, a valve can be used to cut off the connection between the buffer tank and the storage tank, the material feeding back pipe and the material pipe are communicated, so that materials which contain the catalysts enter into the pressure reactor again, and then the catalysts are recycled.
Description
Technical field
The utility model relates to a kind of catalyst recycling recovery system, particularly a kind of catalyst recycling recovery system of avoiding line clogging, improving catalyst utilization.
Background technology
In Chemical Manufacture, usually use the stress reaction that catalyst carries out material, for example the reaction of ortho-nitrochlorobenzene, ortho-nitraniline.In reaction, material and catalyst place pressure reacting container, and pressure reacting container is communicated with storage tank by drainage conduit.When utilizing pressure to discharge material, need to staticly settle catalyst, open again the valve of drainage conduit and discharge material.Usually because precipitation is not thorough, cause the catalyst of suspension to enter next procedure, thus blocking pipe, material pump and condenser, and not only impact is normal produces, and also has certain potential safety hazard.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of catalyst recycling recovery system of avoiding line clogging, improving catalyst utilization.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of catalyst recycling recovery system, comprise pressure reactor, storage tank, described storage tank is communicated with by drainage conduit with pressure reactor, the bottom of pressure reactor is stretched in the import of described drainage conduit, and its innovative point is: also comprise a surge tank, described surge tank is serially connected on the drainage conduit, the bottom of described surge tank is provided with the feed back pipe, and described feed back pipe is communicated with the materail tube of pressure reactor.
Further, the bottom of described surge tank is back taper.
Further, in the described surge tank paddle is set.
The utility model has the advantage of: in drainage conduit one surge tank is set, is used for precipitated catalyst, enter next procedure after avoiding catalyst to enter storage tank.After the surge tank precipitated catalyst, can cut off being connected of surge tank and storage tank by valve, connect feed back pipe and materail tube, again enter in the pressure reactor so that contain the material of catalyst, thereby recycle catalyst.
Description of drawings
Fig. 1 is the utility model catalyst recycling recovery system structural representation.
The specific embodiment
As shown in Figure 1, comprise pressure reactor 1, storage tank 2, drainage conduit 3, surge tank 4, feed back pipe 5.
Above-mentioned storage tank 2 is communicated with by drainage conduit 3 with pressure reactor 1, and the bottom of pressure reactor 1 is stretched in the import of drainage conduit 3.
Operation principle: during discharge, the material in the pressure reactor 1 enters surge tank 4 and storage tank 2 by drainage conduit 3 under pressure, and when entering surge tank 4, most of catalyst can accumulate in the surge tank 4, and few the continuation enters storage tank 2 with material.When surge tank 4 inner catalysts gather more after, cut off being communicated with of surge tank 4 and storage tank 2 by valve, connect feed back pipe 5 and materail tube 6, so that material and catalyst in the surge tank 4 enter pressure reactor 1 again with feed back pipe 5, so that catalyst is fully used.
