Claims (7)

1. Способ транспортировки раствора целлюлозы в водном третичном амин-оксиде через элементы конструкции, в которых раствор целлюлозы имеет различные скорости потока по длине, отличающийся тем, что элементы конструкции снабжены выходами, через которые часть раствора целлюлозы выгружается из этого элемента конструкции в точке, где скорость потока относительно мала.1. A method of transporting a solution of cellulose in an aqueous tertiary amine oxide through structural elements in which the cellulose solution has different flow rates in length, characterized in that the structural elements are provided with outlets through which part of the cellulose solution is unloaded from this structural element at the point where flow rate is relatively low. 2. Способ по п. 1, отличающийся тем, что выход, устанавливаемый на элементе конструкции, сконструирован так, что выгружается такая часть раствора целлюлозы, которая, при смешении с транспортируемой целлюлозой, имеет, при испытании термической стабильности, температуру подъема ниже чем у транспортируемого раствора целлюлозы в пределах 10oC.2. The method according to p. 1, characterized in that the output installed on the structural member is designed so that such a portion of the cellulose solution is discharged that, when mixed with transported cellulose, has, when testing thermal stability, the rise temperature is lower than that of the transported cellulose solution within 10 o C. 3. Способ по п. 2, отличающийся тем, что выход на данном элементе конструкции сконструирован так, что выгружается такая часть раствора целлюлозы, которая, при смешении с транспортируемой целлюлозой, имеет, при испытании термической стабильности, температуру подъема ниже, чем у транспортируемого раствора целлюлозы в пределах 5oC.3. The method according to p. 2, characterized in that the outlet on this structural member is designed so that such a portion of the cellulose solution is discharged that, when mixed with transported cellulose, has, when testing thermal stability, the lift temperature is lower than that of the transported solution cellulose within 5 o C. 4. Способ по одному из пп. с 1 по 3, отличающийся тем, что в качестве элементов конструкции используются фильтр, насос, вентиль, фланец или инжектор обратного потока. 4. The method according to one of paragraphs. 1 to 3, characterized in that the filter, pump, valve, flange or backflow injector are used as structural elements. 5. Устройство для производства продукции сформованной из целлюлозы по амин-оксидному процессу, включающее элемент конструкции для транспортировки раствора целлюлозы, имеющего различные скорости потока по длине элемента, отличающееся тем, что выход для выгрузки части раствора целлюлозы располагается в той части элемента, где скорость потока относительно мала. 5. A device for producing cellulose-molded products by an amine oxide process, comprising a structural member for transporting a cellulose solution having different flow rates along the length of the element, characterized in that the outlet for unloading part of the cellulose solution is located in that part of the element where the flow rate relatively small. 6. Устройство по п. 5, отличающееся тем, что выход на элементе конструкции сконструирован так, что выгружается такая часть раствора целлюлозы, которая, при смешении с транспортируемой целлюлозой, имеет, при испытании термической стабильности, температуру подъема ниже, чем у транспортируемого раствора целлюлозы в пределах 10oС.6. The device according to claim 5, characterized in that the outlet on the structural member is designed so that a portion of the cellulose solution is discharged which, when mixed with the transported cellulose, has, when tested for thermal stability, the lift temperature is lower than that of the transported cellulose solution within 10 o C. 7. Устройство по п. 6, отличающееся тем, что выход на элементе конструкции сконструирован так, что выгружается такая часть раствора целлюлозы, которая, при смешении с транспортируемой целлюлозой, имеет, при испытании термической стабильности, температуру подъема ниже, чем у транспортируемого раствора целлюлозы в пределах 5oС.7. The device according to claim 6, characterized in that the outlet on the structural member is designed so that a portion of the cellulose solution is discharged which, when mixed with the transported cellulose, has, when tested for thermal stability, the lift temperature is lower than that of the transported cellulose solution within 5 o C.
