Description

Изобретение относитс к технике сушки сыпучих термолабильных материалов и может найти применение в химической , металлургической и других отрасл х промышленности.This invention relates to a technique for drying loose thermolabile materials and may find application in the chemical, metallurgical and other industries.

Известен аппарат, в котором имеютс смесители непрерывного действи , состо щие из набора V-образных элементов , соединенных между собой в .разных плоскост х и вращанвдихс вокруг горизонтальной или наклонной оси СП.Недостатком данного аппарата вл етс то, что в нем невозможно проводить процесс адсорбционно-контактной сушки совместно с регенерацией адсорбента.A device is known in which there are continuous mixers consisting of a set of V-shaped elements interconnected in different planes and rotated inverters around a horizontal or inclined axis SP.The disadvantage of this apparatus is that it is impossible to carry out the process of adsorption in it. -contact drying together with the regeneration of the adsorbent.

Наиболее близким к предлагаемому, вл етс тепломассообменный аппарат, содержащий вращавшейс барабан с зигзагообразными трубчатыми элементами , расположенными вдоль барабана в диаметральных плоскост х и подключенными по концам к входной и выходной распределительным камерам, и систему патрубков ввода и вывода теплоносител С 2.Closest to the present invention, there is a heat and mass transfer apparatus containing a rotating drum with zigzag tubular elements located along the drum in diametrical planes and connected at the ends to the input and output distribution chambers, and a system of C 2 input and output nozzles.

Недостаток известного аппарата также заключаетс в том, что в нем невозможно осуществить контактно адсорбционную сушку совместно с регенерацией адсорбента.A disadvantage of the known apparatus is also that it is impossible to carry out contact adsorption drying together with the regeneration of the adsorbent.

Цель изобретени - обеспечение проведени контактно-адсорбционной сушки и регенерации гранулированного адсорбента.The purpose of the invention is to ensure the conduct of contact-adsorption drying and regeneration of the granular adsorbent.

Поставленна цель достигаетс тем, что трубчатые элементы расположены снаружи барабана, а со сто10 роны выходной распределительной камеры внутрь барабана введен патрубок ввода теплоносител дл регенерации адсорбента, причем барабан снабжен системой черпаков и кольцеклх пере15 городок, а выходна распределительна камера - отделителем адсорбента от высушиваемого материала, выполненным в виде цилиндрической перфорированной перегородки.The goal is achieved by the fact that the tubular elements are located outside the drum, and from the side of the outlet distribution chamber, the heat carrier inlet pipe is inserted into the drum for regeneration of the adsorbent, the drum is equipped with a scoop and ring-transfer system, and the outlet distribution chamber is an adsorbent separator from the material being dried, made in the form of a cylindrical perforated partition.

Claims

The device contains a rotating drum 1 mounted on po-peak supports 2. The cavity of drum 1 section 25 has compartments 3 with annular partitions 4. Each compartment 3 has a hopper device in the form of buckets 5. On the outside of drum 1 there are zigzas 0 along the generatrix mixing tubular elements b adjacent to the input 7 and output 8 distribution chambers. The outlet distribution chamber 8 is equipped with a perforated partition 9 and scoops 10, and the drum on this side is provided with a coolant inlet pipe 11. Drum 1 has a full-time 12 and unloading 13 devices. The device works as follows. When the drum 1 rotates together with the mixing tubular elements 6 rigidly connected with it, wet porous material is fed through the device 12 into the inlet distribution chamber 7 and distributed over all the mixing elements 6. At the same time, the regenerated granular adsorbent from the upper drum 3 compartment 1. The mixture of material and adsorbent moves in the tubular elements in the direction of the inclination of the axis of the drum 1, making a complex reciprocating motion. When this occurs, the transfer of moisture from the material to the adsorbent, due to the difference in their capillary potentials. From the mixing elements, the mixture of dry powder and the wet granulated adsorbent enters the chamber 8, equipped with a cylindrical perforated partition 9, where the dried material separates from the adsorbent, and the material passed through the perforation is discharged through the device 13, and the wet adsorbent from the annular chamber 8 with scoops 10 is supplied to the lower compartment 3 of the drum 1 for thermal regeneration. Next, the granulated adsorbent moves towards the top of the drum head 1 prc, using the scoops 5, while the ONM adsorbent is heated by a hot coolant flowing through the nozzle 11, and is regenerated. From the upper head of the drum 1, the regenerated adsorbent re-enters the mixing elements 6. The spent heat carrier is removed from the upper head of the drum 1 together with a small amount of dust from the end of the adsorbent. Combining the process of drying and regeneration of the adsorbent in one unit allows reducing the production area occupied by the equipment. The invention The heat and mass transfer apparatus containing a rotating drum with zigzag tubular elements located along the drums of diametrical planes and connected at the ends to the inlet and outlet distribution chambers, and a system of inlet and outlet heat carrier, which distinguishes RH from the fact that, in order to provide carrying out contact-and sorption drying and regeneration of the granulated adsorbent, the tubular elements are located outside the drum, and from the side of the exhaust distribution chamber in The drum inside is provided with a heat transfer agent inlet for regeneration of the adsorbent, the drum is equipped with a scoop and ring partitions system, and the outlet distribution chamber is equipped with a separator of the adsorbent from the material being dried made in the form of a cylindrical perforated partition.
