Abstract

Изобретение относитс к технике сушки и может быть использовано в различных отрасл х промышленности. Цель изобретени - интенсификаци процесса сушки и повышение ее равномерности. Установка состоит из теплогенератора 1, воздуходувки 2,с эксгаустера 3, питател 4 сыпучего материала и пневмосушилки 5 Последн имеет спиральную пневмотрубу 6, обечайки 7 и 8, теплообменник с центральной трубой 10, насадкой-завихрителем 11 потока и ребрами 9. Пневмотруба с обечайками образуют камеру 12, в верхней части которой расположена выхлопна труба 13 с жалюзийным отводом 14 и дроссельной заслонкой 15 Надсепарационным пространством камеры 12 расположен двухходовой регенеративный теплообменник 16. Коническа часть обечайки 7 имеет патрубок 17 и выгрузное устройство 18. Внутренн обечайка 8 в нижней цилиндрической части 19 имеет профилированную винтообразную поверхность с каналами, совпадающими с направлением потока, образованного насадкой-завихрителем 11.1 з. п. ф-лы, 8 ил.This invention relates to a drying technique and can be used in various industries. The purpose of the invention is to intensify the drying process and increase its uniformity. The installation consists of a heat generator 1, a blower 2, an exhauster 3, a feeder 4 bulk material and a pneumatic dryer 5 The latter has a spiral pneumatic tube 6, shells 7 and 8, a heat exchanger with a central tube 10, a flow swirl nozzle 11 and fins 9. A pneumatic tube with shells form chamber 12, in the upper part of which there is an exhaust pipe 13 with a louver outlet 14 and throttle valve 15; the over-separation space of chamber 12 is a two-way regenerative heat exchanger 16. The conical part of the shell 7 has a pat ubok Unloading device 17 and 18. The inner shroud 8 in the lower cylindrical part 19 has a profiled surface with helical channels coinciding with the flow direction, a nozzle-formed swirler 11.1 h. the item of f-ly, 8 ill.

Claims

Claim

1. Installation for drying dispersed materials, containing a spiral pneumatic tube enclosed in cylindrical shells, limiting the separation space and the drying chamber and connected at the inlet to the feeder of the dried material, and at the outlet communicated with the separation space, over which a two-way heat exchanger is installed, one stroke of which is turned on to the exhaust coolant discharge line and connected to the separation space, and its other stroke is connected to the blower on one side and connected to the gap on the other between the shells, and also an additional heat exchanger in the form of a central pipe installed coaxially with the pneumatic tube with radial hollow ribs connected to the gap between the shells, while the shells are conical in the lower part, characterized in that. in order to intensify the drying process, the installation additionally contains an exhaust pipe, the central pipe in the upper part is equipped with a swirl nozzle, and the inner shell in its lower cylindrical part is made in the form of a profiled spiral surface, the spiral pipe is tangentially connected to the separation space, the exhaust pipe is made with a louver a tap connected to the discharge path of the waste coolant of a two-way heat exchanger is equipped with a throttle and is connected to the heatlog to the nerator.

2. Installation pop. 1, characterized in that, in order to increase the uniformity of drying, the hollow ribs of the Central pipe are connected by means of additionally installed one or more concentric annular partitions, Fig.2 fi? 3
