Claims (14)

1. Устройство обработки среды, содержащее по меньшей мере две камеры, а именно первую камеру и вторую камеру, выполненные с обеспечением возможности протекания среды через них, причем эти две камеры разделены по меньшей мере одним запираемым соплом, причем указанное запираемое сопло имеет суживающуюся часть на входе, узкую часть, уступ, обращенный назад, сразу после узкой части и выходную часть на выходе, ведущем во вторую камеру, причем запираемое сопло сконструировано для обеспечения кавитации в результате воздействия запертого потока в нормальных рабочих условиях.
2. Устройство обработки среды по п. 1, отличающееся тем, что сужающаяся часть, узкая часть и выходная часть имеют круглую форму в поперечном сечении, а выходная часть расширяется.
3. Устройство обработки среды п. 1, отличающееся тем, что устройство включает смешивающие сопла для смешивания сред до попадания в запираемое сопло или после выхода из запираемого сопла, либо в обоих местах сразу, причем смешивающее сопло имеет суживающуюся часть на входе, узкую часть, уступ, обращенный назад, сразу после узкой части и выходную часть на выходе, ведущем во вторую камеру.
4. Устройство обработки среды по п. 1, отличающееся тем, что сужающаяся часть сопла имеет угол раскрытия от 1 до 35°.
5. Устройство обработки среды по п. 4, отличающееся тем, что угол раскрытия составляет от 15 до 35°.
6. Устройство обработки среды по п. 1, отличающееся тем, что уступ запираемого сопла, обращенный назад, выступает в радиальном направлении наружу за пределы узкой части на 3-10% диаметра узкой части.
7. Устройство обработки среды по п. 6, отличающееся тем, что уступ, обращенный назад, выступает в радиальном направлении наружу за пределы узкой части на 4-8%.
8. Устройство обработки среды по п. 1, отличающееся тем, что выходная часть расширяется с углом раскрытия от 1 до 8°.
9. Устройство обработки среды по п. 8, отличающееся тем, что выходная часть расширяется с углом раскрытия от 2 до 8°.
10. Устройство обработки среды по п. 1, отличающееся тем, что устройство предназначено для диффузии газа в среде, причем вторая камера содержит один или несколько впусков газа, чьи оси перпендикулярны оси сопла, чтобы газ мог направляться в сторону потока, который обычно двигается по касательной относительно сопла или имеет завихряющее действие.
11. Устройство обработки среды по п. 1, отличающееся тем, что расширяющаяся часть сопла имеет дополнительные уступы, обращенные назад, вдоль выходной части.
12. Способ улучшения химических или физических реакций, возникающих при использовании запертого потока, причем такой способ включает прохождение среды через запираемое сопло, содержащее суживающуюся часть на входе, узкую часть, уступ, обращенный назад, сразу после узкой части и выходную часть, причем направленный поток, угловая скорость, центробежное ускорение и прямолинейное ускорение среды создают условия, обеспечивающие запертый поток через запираемое сопло.
13. Способ по п. 12, отличающийся тем, что способ включает диффузию газа в среде и создание пузырьков в среде, которая ускоряется через узкую часть и затем обеспечивает разрыв пузырьков и образование множества пузырьков меньшего размера.
14. Способ по п. 12, отличающийся тем, что способ является частью способа отделения золота и других металлов от руды, в котором кислород или воздух достаточно диффундированы в суспензии измельченной руды, воды и цианида кальция или натрия для достаточного окисления руды с целью снижения потребления цианида и/или улучшения выщелачивания металлов и/или упрощения флотации частиц золота из руды.
