Title:
ELECTROSPRAY DEVICE FOR FLUIDIZED-BED APPARATUS, AND FLUIDIZED-BED APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/075603
Kind Code:
A1
Abstract:
Disclosed are an electrospray device (1) for a fluidized-bed apparatus (10), the fluidized-bed apparatus (10), and a fluidized-bed method. The electrospray device (1) comprises a spray gun (60) and a guide cylinder (50) coaxially and vertically positioned with the spray gun (60), wherein the spray gun (60) comprises a spray gun body (62), the top of the spray gun (60) is provided with a nozzle (61), the spray gun body (62) is provided with a cyclone generator (70) for generating a cyclone, and a power source (100) is directly or indirectly connected between the nozzle (61) and the guide cylinder (50) so as to apply voltages to the nozzle (61) and the guide cylinder (50). The fluidized-bed apparatus (10) comprises a product container (20), an inflation base (30) located at a lower portion, an air distribution plate (40) arranged between the product container (20) and the inflation base (30), and the electrospray device (1). When the power source (100) applies voltages of opposite polarities to the nozzle (61) and the guide cylinder (50), the fluidized-bed apparatus (10) is used for coating particles; and when the power source (100) applies voltages of the same polarity to the nozzle (61) and the guide cylinder (50), the fluidized-bed apparatus (10) is used for spray-drying a solution. The electrospray device (1) uses an electromagnetic hydrodynamics method to improve the performance of the fluidized-bed apparatus (10) and optimize the process of products.
