PULSE-6 TYPE DRIER FOR SOLUTIONS AND PULPS Russian patent published in 2009 - IPC F26B3/12 

Abstract RU 2348874 C1

FIELD: heating; drying.

SUBSTANCE: invention is referred to disperse material drying technologies and may be used in microbiological, food, chemical and other industries. The drier for solutions and pulps consists of a body, where pneumatic injector for dried solution or pulp supply is located. The solution or pulp is sprayed under furnace gases effect. The material granules being produced in the course of drying process are supplied to gas-distributing lattice and dried completely in the boiling bed created by coolant supplied to the lower part of the body under the lattice. The coolant at the temperature to 200°C is supplied to the lower part of the body under the lattice and though the part of the body, which is separated from the tapered part with gas-distributing lattice by means of the cup with perforated bottom. The coolant is removed through the perforations of cylindrical cup and supplied to entrapping system consisting of an acoustic plant, cyclone and sleeve filter. The pneumatic injector is made acoustic and contains housing with ultrasonic vibrator in the shape of nozzle and resonant cavity being installed inside and pipes for air and solution supply. In addition, the housing is implemented as a cup with bottom where cylindrical cavity is provided for solution supply through the pipe located in the lid. The upper part of the lid includes fastening element, which fixes the upper part of the resonant cavity rod in the nozzle. The upper part of the rod is hinge-connected with the lower part of resonant cavity in the lid of at least one fixing disc implemented in the shape of, at least, three elastic leaves interacting with the inner surface of conic opening of the lid. There is a slotted channel between the opening in the body bottom and inner surface of the nozzle. The solution is supplied through the above channel. The annular channel is made between the inner surface of the conic opening and outer surface of the lower rod part. The annular channel is used for spraying furnace gas supply.

EFFECT: increased drying efficiency.
