Description

(54) СПОСОБ УПРАВЛЕНИЯ ПРОЦЕССОМ СУШКИ ТРУБ(54) METHOD FOR MANAGING THE DRYING OF PIPES

Изобретение относитс  к энергетике , в частности к управлению процессом сушки труб, и может быть использовано в авиастроении,химической и других отрасл х промышленности. Известен способ управлени  процессом сушки труб путем продувки через них воздуха 1 . Однако способ не позвол ет дости - нуть требуемого качества сушки и требуемый КПД, так как при этом не учитывают степень качества сушки и не контролируют величины нагрева. Цель изобретени  - повышение качества сушки и снижение энергозатрат. Поставленна  цель достигаетс  тем, что продувку производ т путем просасы вани  через трубы наружного воздуха при одновременном их нагреве. Кроме того, нагрев труб производ т до температуры кипени  воды при созда ваемом в трубах разрежении. На чертеже представлена схема сушилки , реализующей данный способ управлени . Сушка производитс  через полость 1, осушитель 2, выводной наконечник 3, дроссель 4, входной наконечник S, указатель влажности 6 и датчик 7. Устройство работает следующим образом. Сушка полости трубы 1 производитс  продувкой через нее под разрежением осушенного в сушителе 2 атмосферного воздуха. Продувка под разрежением достигаетс , например, за счет откачки воздуха из полости трубы 1 через выводной наконечник 3, соединенный с вакуумным устройством, и дросселировани  воздуха на входе в трубу 1 с помощью дроссел  4, размещенного во входной магистрали . Одновременно с продувкой трубу 1 нагревают по контуру, например, методом электросопротивлени , подвод The invention relates to the energy sector, in particular, to the control of the drying process of pipes, and can be used in the aircraft industry, chemical and other industries. There is a known method for controlling the drying process of pipes by blowing air through them 1. However, the method does not allow to achieve the required quality of drying and the required efficiency, since it does not take into account the degree of quality of drying and does not control the amount of heat. The purpose of the invention is to improve the quality of drying and reduce energy consumption. This goal is achieved by blowing through the external air pipes while heating them. In addition, the pipes are heated to the boiling point of water at the underpressure created in the pipes. The drawing shows a diagram of the dryer that implements this method of control. Drying is carried out through cavity 1, desiccant 2, outlet tip 3, throttle 4, inlet tip S, humidity indicator 6 and sensor 7. The device works as follows. Drying of the cavity of the pipe 1 is carried out by blowing through it under vacuum of atmospheric air dried in the dryer 2. Purging under vacuum is achieved, for example, by pumping air from the cavity of the pipe 1 through the outlet tip 3 connected to a vacuum device and throttling the air entering the pipe 1 with the help of throttles 4 located in the inlet line. Simultaneously with the purge, the pipe 1 is heated along the contour, for example, by the method of electrical resistivity, the supply
