Abstract

The invention relates to a rotary kiln type spray-drying system with a compact structure. The system comprises a feeding system, a hot air system, a tail gas purification device and a spray-drying device, wherein the spray-drying device comprises a horizontal drying cavity and a wheel set, the horizontal drying cavity comprises a front portion, a rear portion and a middle portion movably connected with the front portion and the rear portion, and the front portion comprises an air guiding and distributing hood and an atomization nozzle which are arranged in sequence; the feeding system is communicated with the atomization nozzle, the hot air system is communicated with the front portion of the cavity, and the tail gas purification device is communicated with the rear portion of the cavity. An atomizing system is installed in a traditional rotary kiln type drier creatively, so that the rotary kiln type drier has the characteristics of a spray drier. Meanwhile, the dwell time of materials in the drying cavity is prolonged greatly, so that a drying effect which can not be realized by means of ordinary spray-drying equipment is realized. Due to the fact that the horizontal rotary kiln type drier cavity is adopted in the technical scheme, equipment height is reduced greatly, the yield is high after drying, and practicality is high.

Description

Technical field [0001] The invention relates to the technical field of structure design of spray drying device products, and more specifically to a rotary kiln type spray drying system with a compact structure. Background technique [0002] The application of ordinary spray drying equipment is very extensive. It has been applied in the fields of milk (egg) product processing, chemistry, pharmaceuticals, food, ceramics, environmental protection, new materials, aerospace and other industries, covering almost most of the existing industries field. The spray drying device can make the slurry with higher solid content be atomized and granulated, and dried into spherical granular or powdered products. The principle of the spray drying process is: spray liquid raw materials into mist droplets in the drying chamber, and then use hot air to dry the droplets to obtain granular or powdered products. The drying chamber of the existing spray drying device adopts a "cylindrical + cone" tower...
