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 structural design of spray drying device products, and more specifically relates to a compact rotary kiln spray drying system. Background technique [0002] Ordinary spray drying devices are widely used. At present, they have been used in dairy (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 atomize and granulate the slurry with high solid content, and dry it into spherical granular or powdery products. The principle of the spray drying process is: spray the liquid raw material into mist droplets in the drying chamber, and then dry the droplets with hot air to obtain granular or powder products. The drying chamber of the existing spray drying device adopts a "cylindrical + conical" tower structure design. The atomizing head is ...
