High-speed centrifugal drying method and drying system for implementing method

Abstract

The invention discloses a high-speed centrifugal drying method, which comprises the following steps of: installing a hot-air drying device, a to-be-dried material conveying device and a tail gas filtering device; when the hot-air drying device works, filtering air to form high-speed airflow; heating the airflow and then jetting the airflow into a drying tower through a pipeline to form high-speed rotary hot airflow; when the to-be-dried material conveying device works, filtering a to-be-dried material and then conveying to a centrifugal atomizer at the top part of a dryer to form atomized liquid drops jetted into a drying room; enabling the atomized liquid drops to be contacted with the high-speed rotary hot airflow, and then, drying to form finished products; delivering the finished product from an outlet at the bottom part of the drying tower; separating tail gas entering the tail gas filtering device through a plurality of cyclone separators in sequence; delivering the finished products mixed in the tail gas from outlets at the bottom parts of the cyclone separators; further filtering the tail gas to remove dust; and then, discharging to the air to finish a high-speed centrifugal drying process. The invention also discloses a drying system.

Description

technical field [0001] The invention relates to drying equipment, in particular to a high-speed centrifugal drying method for drying materials in the form of emulsion, suspension, paste or solution and a drying system for implementing the method. Background technique [0002] In the prior art, in many production industries, it is necessary to dry materials in the state of emulsion, suspension, paste, solution, etc. into powder or granular products. Widely used process. It is most suitable for producing powder, granular or block solid products from solutions, emulsions, suspensions and plastic paste liquid raw materials. Therefore, spray drying is an ideal process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet precise standards. However, the drying methods currently used in the industry are not very ideal. There are problems such as low drying efficiency, unstable drying quality, high loss ra...
