Description
Известны способы сушки каиилл рно-порисгых материалов, наиример пиломатериалов, путем нагрева погруженного в воду высушиваемого материала с помощью размешенных в нем электродов.There are known methods for drying porous-porous materials, naimer lumber, by heating the material to be submerged in water using electrodes placed in it.
Цель изобретени - интенсификаци теплои массообмена.The purpose of the invention is the intensification of heat and mass transfer.
Достигаетс это благодар тому, что с помош ,ью теплообменника поддерживают температуру воды ниже температуры высушиваемого материала на .This is achieved due to the fact that with the help of the heat exchanger the water temperature is kept below the temperature of the dried material on.
Предложенный способ осуществл ют следующим образом. Высушиваемый материал с размещенными в нем электродами, .которые подключены к источнику тока, помещают в емкость с водой. Воду нагревают от 60 до 95°С от внешнего источника тепла и по достиженин заданной температуры включают электроды . Когда темнература высушивае.мого материала превысит температуру воды на 4- б°С, включают теплообменник дл отвода избытка тепла, выдел емого электродами, и поддержани данной разности температур.The proposed method is carried out as follows. The material being dried with electrodes placed in it, which are connected to the current source, is placed in a container with water. Water is heated from 60 to 95 ° C from an external heat source and, upon reaching a predetermined temperature, switches on the electrodes. When the dead temperature of the dried material exceeds the temperature of the water by 4B ° C, a heat exchanger is included to remove the excess heat generated by the electrodes and to maintain this temperature difference.
Пред.мет изобретени Prev Invention
Способ сушки .капилл рно-пористых материалов , например пиломатериалов, путем нагрева погруженного в воду высушиваемого материала при помощи размещенных в нем электродов , отличающийс тем, что, с целью интенсифика ции тепло- и массообмена, температуру воды с помощью теплообменника поддерживают ниже температуры высушиваемого материала на 4-6°С.The method of drying capillary-porous materials, such as lumber, by heating the submerged material to be dried by means of electrodes placed in it, characterized in that, in order to intensify heat and mass transfer, the temperature of the water is maintained below the temperature of the material being dried at 4-6 ° C.
