The equipment starts to work, the fluidized bed 2 blows upwards, and the materials are in a boiling state in the drying tower 1. At this point the spray units start working synchronously. The telescopic rod 32 reciprocates, and the limiting frame at the tail end of the telescopic rod 32 is driven to reciprocate up and down. When the limiting frame moves up and down, the threaded seat in the limiting frame is in threaded fit with the threaded shaft 31, the threaded seat rotates continuously, and the spray head 364 on the threaded seat rotates along with the threaded seat. The spray head 364 is connected with an external liquid supply device, the rotating spray head 364 can spray atomized liquid drops at a plurality of angles, and by matching up and down reciprocating movement, all directions in the drying tower 1 can be covered by the atomized liquid drops, and the powder and the liquid drops in the drying tower 1 are fully mixed. And the two threaded seats are provided with the spray heads 364, so that the atomized liquid drops sprayed out can be contacted with each other. The fluidized bed 2 at the bottom of the drying tower 1 blows air upwards, part of the air enters the space between the inner barrel and the tower wall of the drying tower 1 through the circular cylinder 44 and is discharged from the air outlet 42 under the action of the air deflector 43, in the embodiment, the air deflector 43 inclines downwards, the air blown out from the air outlet 42 is guided downwards, the materials adhered or about to be adhered on the inner barrel 41 are blown away, and the condition of wall adhesion is avoided. Meanwhile, the drying device provided by the application is a vertical parallel-flow upper-exhaust pressure spray drying tower 1, the air is exhausted upwards in the working process, and an annular air curtain is formed on the tower wall of the drying tower 1 in the upward movement of the air, so that the wet powder is isolated from the tower wall, the powder adhesion and deposition on the tower wall are prevented, and the function of preventing the wall adhesion is further achieved.
In this embodiment, a cyclone separator and a bag-type dust collector are further disposed at the top of the drying tower 1, about 15-20% of fine powder and wet air are sucked into the cyclone separator and the bag-type dust collector from an air outlet pipe at the top of the drying tower by a draught fan for separation, and tail gas is exhausted into the atmosphere through the draught fan. The fine powder separated from the cyclone separator and the bag-type dust collector returns to the drying tower 1 through a powder returning system to be agglomerated with the atomized material beads. If the fine particles screened at the bottom of the drying tower 1 do not meet the particle requirement, the fine particles can also be returned to the drying tower 1 by the powder returning system to be agglomerated into particles again. Improve the quality of the materials.
In this embodiment, an electrostatic field is disposed near the spray head 364, the externally supplied liquid is delivered from the liquid supply device to the spray head 364, and the high-voltage electrostatic field is applied to promote the rapid transfer of the more polar solvent in the suspension to the surface of the particles, so as to promote the electrostatic charge in the droplets to expel water molecules out of the droplets for evaporation, i.e., the moisture is transferred from the local or internal part to the surface of the droplets, and the transfer of the moisture allows the formation of the charged solid powder.
By controlling the voltage applied to the atomized droplets, some particles dry quickly while others dry gradually, leaving the surface more wet and sticky, the two types of particles aggregate together to form larger particles, and a very fluid product with predominantly large particles (less fine particles) is ultimately obtained.
In suspension or local agglomeration, the moisture is transferred from the droplets to the atomizing drying zone and the fluidized bed 2 and is then collected and de-energized via a grounded collection box. The manner of setting the electrostatic field in this embodiment is a conventional electrostatic spray setting manner.
This practice provides a spray fluidized granulation drying apparatus that produces a free flowing powder or granules during agglomeration forming or granulation that contains very little dust and which can dry thermoplastic and hygroscopic products that many other devices cannot process. The drying equipment of the heat-sensitive product is ideal because the temperature of the granules is always kept low. In addition, fluidization, drying and granulation are all finished at a lower exhaust temperature, so that efficient utilization of energy is facilitated, the lower the exhaust temperature is, the higher the heat exchange rate is, the higher the heat utilization rate is, and the more energy is saved.
