Description
Изобретение относитс к холодильной технике , а точнее к способам разделени воздуха в вихревой трубе. Известны способы разделени воздуха в вихревой трубе, имеющей сопловой ввод и камеру энергетического разделени , путем предварительного охлаждени воздуха, последующей подачи одной его части в сопловой ввод дл образовани холодного и нагре того потоков, а второй части - в камеру энергетического разделени со стороны выхода нагретого потока 1). Однако этими способами нельз получать в холодном потоке чистый азот, а в нагретом - чистый кислород. Дл получени в холодном потоке чистого азота а в нагретом - чистого кислорода в процессе предварительного охлаждени воздух довод т до влажного состо ни и после его разделени из второй части отдел ют полученную жидкость, переохлаждают последнюю холодным потоком до температуры , на 2-5°С превышающей температуру этого же потока, и в камеру энергетического разделени подают эту переохлажденную жидкость, а оставшийс после отделени жндкостн осушенный воздух смешивают с первой частью перед ее подачей в сопловой ввод. На фиг. 1 показана установка дл осуществлени предлагаемого способа (переохлажденна жидкость подаетс в камеру энергетического разделени по оси вихревой трубы); на фиг. 2 - то же, но переохлажден на жидкость подаетс в камеру энергетического разделени тангенциально; на фиг. 3 показана та же установка в положении, когда жидкость переохлаждаетс холодным потоком внутри камеры энергетического разделени , после чего подаетс по оси вихревой трубы. Предлагаемый способ осуществл етс следующим образом. Охлажденный до влажного состо ни воздух раздел ют на две частн, одну из которых подают по линии 1 в отделитель 2 жидкости , а вторую - в сопловой ввод 3 вихревой трубы дл образовани в камере 4 энергетического разделени холодного и подогретого потоков. Холодный поток, содержащий чистый азот, направл ют через диафрагму 5 и теплообменник 6 к потребителю. а подогретый поток, содержащий чистый кислород, через патрубок 7 такжг напраThe invention relates to refrigeration, and more specifically to methods for separating air in a vortex tube. Methods are known for separating air in a vortex tube having a nozzle entry and an energy separation chamber by pre-cooling the air, then feeding one part of it into the nozzle input to form cold and heated flows, and the second part entering the energy separation chamber from the exit side of the heated flow one). However, these methods cannot produce pure nitrogen in a cold stream, and pure oxygen in a heated stream. To obtain pure nitrogen in the cold stream and pure oxygen in the pre-cooling process, the air is brought to the wet state and, after its separation, the resulting liquid is separated from the second part, supercooled the latter with a cold stream to a temperature 2-5 ° C higher than the temperature of the same flow, and this supercooled liquid is supplied to the energy separation chamber, and the dried air remaining after separation is mixed with the first part before it is fed to the nozzle entry. FIG. Figure 1 shows an installation for carrying out the proposed method (the supercooled liquid is supplied to the energy separation chamber along the axis of the vortex tube); in fig. 2 - the same, but supercooled liquid is supplied tangentially into the energy separation chamber; in fig. Figure 3 shows the same installation in the position where the liquid is supercooled with a cold stream inside the energy separation chamber, after which it is fed along the axis of the vortex tube. The proposed method is carried out as follows. The air cooled to the wet state is divided into two parts, one of which is fed through line 1 to the liquid separator 2, and the second to the nozzle inlet 3 of the vortex tube to form cold and heated flows in the chamber 4. A cold stream containing pure nitrogen is directed through diaphragm 5 and heat exchanger 6 to the consumer. and the preheated stream containing pure oxygen through pipe 7 is also directed to
