Mouth, thermal source outlet；It is characterized in that the side of at least one baffle plate is provided in the baffle plate that reactive tank is installed
There is the diversion pipe of upper and lower opening, the under shed of the diversion pipe is located at the bottom of reactive tank, and the upper opening of diversion pipe is located at anti-
Answer the top of slot；Discharge port is located at the groove body bottom center of reactive tank；Modification two of the discharge port through liquid pump and spray-drying installation
Silica slurry import is connected；The spray-drying installation includes drying tower, is provided with centrifugal spray at the top of drying tower and sets
Standby, the bottom of drying tower is improved silica discharge port, and improved silica discharge port connects the bag hose of a tape pulse,
The left and right sides of drying tower are provided with stream pressure spraying apparatus, and stream pressure spraying apparatus includes compressed air inlet and changes
Property silica slurry import.
Blender, liquid pump, centrifugal spray equipment and the stream pressure spraying apparatus is connect with microprocessor respectively.
The advantages of the utility model: the utility model is installed additional on the baffle plate side of the reactive tank of original reforming apparatus
Diversion pipe, the installation direction of diversion pipe are generally with the axis direction of reactive tank parallel or similar to parallel, open under diversion pipe
Mouth is located at the bottom of reactive tank, and the upper opening of diversion pipe is located at the top of reactive tank, and not every baffle plate all installs water conservancy diversion
Pipe, the installation number of diversion pipe is to install on demand；Reactive tank makes in reactive tank under the stirrer paddle effect of blender in this way
The under shed that bottom reaction liquid passes through diversion pipe is entered the upper opening water conservancy diversion of diversion pipe to upper layer, thus just in the middle part of diversion pipe
It is faster uniformly mixed in reaction mass, can not only increase the stability of reaction in this way, but also the quality of product can be improved.This
The spray-drying installation of utility model has stream pressure spraying apparatus.The finished particle degree of this press atomization equipment production can be thick
Change, centrifugal spray equipment and stream pressure spraying apparatus both equipment are combined together, to reach the multi-purpose effect of a tower
Fruit.
