Изобретение относитс к химической, микробиологической и пищевой промышленности и может быть использовано дл контакта газа и жидкости в процессах хемо- сорбции, физической абсорбции, дл выращивани микроорганизмов, дл очистки сточных вод.The invention relates to the chemical, microbiological and food industries and can be used for the contact of gas and liquid in the processes of chemisorption, physical absorption, for the cultivation of microorganisms, for the purification of wastewater.
Цель изобретени - повышение эффективности работы устройства.The purpose of the invention is to increase the efficiency of the device.
На фиг.1 изображено устройство, провырезах ). Засасываемый сверху газ вступает сначала в контакт со свежей жидкостью из форсунок, а затем уже с подсасываемой снизу жидкостью. Последующий контакт происходит при прохождении дисперсии через направл ющий лопаточный аппарат 3 и в результате эффективного перемешивани уже в объеме жидкости за счет встречного движени вращающихс потоков дисперсии: от струи - в сторону, противодольный разрез; на фиг.2 - то же, вид ю положную направлению вращени колеса 4,Figure 1 shows the device, the notches). The gas that is sucked from above comes first into contact with fresh fluid from the nozzles, and then with the fluid that is sucked from below. The subsequent contact occurs when the dispersion passes through the guide vane apparatus 3 and, as a result of effective mixing, already in the liquid volume due to the oncoming movement of the rotating dispersion flows: from the jet to the side, the anti-slit cut; 2 is the same, as seen from the direction of rotation of the wheel 4,

Устройство содержит статор 1 со средством подвода газа в виде центрального патрубка 2 и лопаточным направл ющим аппаратом 3, внутри которого концентрично расположено полое колесо 4,- образованное двум дисками 5 и 6 с наружными радиальными лопатками 7, и имеющее отверсти 8 на периферии.The device comprises a stator 1 with a means for supplying gas in the form of a central nozzle 2 and a blade guide device 3, inside which a hollow wheel 4 is concentrically arranged, formed by two disks 5 and 6 with outer radial blades 7, and having openings 8 at the periphery.
Колесо 4 выполнено с вырезами на периферии, каждый из которых образован радиальной 9 и наклонной к ней 10 перегородками . Отверсти 8 размещены в радиальных перегородках 9 и снабжены тангенциально направленными форсунками 11.Wheel 4 is made with peripheral notches, each of which is formed by a radial 9 and 10 partitions inclined to it. The holes 8 are located in the radial partitions 9 and are equipped with tangentially directed nozzles 11.
Колесо 4 снабжено сообщенным с его полостью центральным трубопроводом подачи жидкости 12 и установлено на нем свободно . Полость колеса сообщена с трубопроводом посредством отверстий 13. Конец трубопровода заглушен. Колесо 4 снабжено ко- 30, ническими кольцами 14, размещенными на лопатках 7.Wheel 4 is supplied communicated with its cavity by the Central pipeline supply fluid 12 and installed on it freely. The wheel cavity communicates with the pipeline through the holes 13. The end of the pipeline is plugged. The wheel 4 is equipped with banana rings 14 placed on the blades 7.
Устройство работает следующим образом.The device works as follows.
Жидкость по трубопроводу 12 через отверсти 13 поступает в полость колеса 4 и выходит стру ми из форсунок между коническими кольцами 14. Под действием реактивных сил вытекающих струй жидкости колесо 4 с форсунками 11, лопатками 7, коническими кольцами 14 вращаетс , осуществл всасывание в полость между лопатками газа - сверху из патрубка 2 и жидкости - снизу из объема жидкости.The fluid through the conduit 12 through the holes 13 enters the cavity of the wheel 4 and jets out of the nozzles between the conical rings 14. Under the action of the reactive forces of the outgoing jets of liquid, the wheel 4 with the nozzles 11, the blades 7, the conical rings 14 rotates, sucking into the cavity between the blades gas - from the top of the pipe 2 and the liquid - from the bottom of the liquid volume.
Самовсасывающий эффект устройства усиливаетс за счет эжектировани струей газа и жидкости из форсунок 11, расположенных р зоне пониженного давлени (вThe self-priming effect of the device is enhanced by the ejection of a jet of gas and liquid from the nozzles 11 located in the reduced pressure zone (in
и от направл ющего лопаточного аппарата 3.and from the guide vane apparatus 3.
Таким образом, струи, выход щие из форсунок, служат не только дл гидропривода , но и дл дополнительного эжектировани газа и жидкости, что способствует увеличению количества подсасываемого газа и циркулирующей жидкости и увеличению скорости процесса массопередачи.Thus, the jets emanating from the nozzles serve not only for the hydraulic drive, but also for additional ejection of gas and liquid, which contributes to an increase in the amount of suction gas and circulating fluid and an increase in the speed of the mass transfer process.
При этом происходит контакт со свежим газом всего свежего количества жидкости, 2Q подаваемой через форсунки, что увеличивает скорость процесса и эффективность использовани газа.When this happens, fresh gas comes in contact with all the fresh amount of liquid 2Q supplied through the nozzles, which increases the process speed and gas utilization efficiency.
Кроме того, благодар расположению форсунок в зоне пониженного давлени , уменьщаетс расход энергии на подачу жид- 25 кости.In addition, due to the location of the nozzles in the zone of reduced pressure, the energy consumption for the liquid supply is reduced.
