Изобретение относитс к водораспылительным устройств и может найти щплМенеиие в энергетике при декарбонизации воды и ржиганви жидкого топлива.в водоснабжении при удалении двухвалентного железа из подземных вод.при окислении сточвых вод в химической промышленности - при десорбции газов.The invention relates to water-spray devices and can be found in the power industry in the decarbonization of water and liquid fuel in the water supply in the removal of ferrous iron from groundwater in the oxidation of wastewater in the chemical industry — in the desorption of gases.

Известна распылительна головка, содержаща конусное сопло и закрепленную „ на его выходном конце ступенчатую насад ку с увеличивающа с по ходу движени жидкости диаметром Г I.A spray head is known, which contains a tapered nozzle and a stepped nozzle attached to its outlet end, which increases with the flow of a fluid with a diameter of DI.

Недостатком ее вл етс низка диоперсность распыла, незначительна зона вакуума.Its disadvantage is the low diopersity of the spray, a slight vacuum zone.

Известна также вакуумно-распылительна головка, содержани конусообразное сужаклщеес по ходу движени жидкости сопло, закрепленный на его выходном це цилиндрический насадок и охватыван ший сопло с насадком с образованием кольцевой камеррз цилиндрический патру. бок 2.Also known is a vacuum-spray head, a cone-shaped nozzle narrowing in the direction of the fluid flow, a cylindrical nozzle attached to its outlet and a covered nozzle with a nozzle with the formation of an annular chamber chamber cylindrical patra. bock 2.

Данна вакуумно-распылительна головка овп етс наиболее блажим к изс бретению по технической сущности и достигаемому результату-.This vacuum spray head is most suitable for the technical essence and the achieved result.

Недостатке ее вл етс звачительное давление перед головкой, сложность конструкции и недостаточна эффективность работы вследствие многоступенчатости .насадки..Its disadvantage is the pressure in front of the head, the complexity of the design and the lack of operational efficiency due to the multi-stage nozzle.

Целью изобретени вл етс упрощение конструкции и повышение эффективности распылени .The aim of the invention is to simplify the design and increase the spray efficiency.

Claims

Specified; The goal is achieved by the fact that in a vacuum nozzle head containing a cone-shaped nozzle tapering in the direction of fluid flow, a cylindrical nozzle fixed to the exit of its end, and a cylindrical nozzle enveloping the nozzle with a nozzle to form a collar chamber . I The drawing shows a vacuum-spray head, general view. The vacuum-sprayed head contains a cone-shaped nozzle 1 tapering in the direction of fluid flow, a cylindrical nozzle 2 attached to its outlet end and a cylindrical nozzle 4 enclosing the nozzle 1 with nozzle 2 to form an annular chamber 3 A cylindrical nozzle 4 5. Vacuum spray head works as follows. The transit jet flows from the cone-shaped nozzle 1 into the nozzle 2, in which a spherical vacuum zone 6 is formed during compression. From the nozzle 2, the jet enters the cylindrical nozzle 4 of a much larger diameter and length which it creates an annular vacuum zone 7. Vacuum in this zone contributes to the breakthrough of air through the holes 5 (perforation) from bottom to top towards the two existing jet. In its upward movement, the air saturates the moving jet and carries out the fragmentation of the flow of a couple of drops of water. A part of the air rises to the annular vacuum zone 7, from where a part of it is sucked off by a jet stream. In this case, the driving force of the desorption increases as the process takes place in a vacuum. The propulsive jet, the passage of the nozzles 2 and the nozzle 4 are constantly located in the vacuum zone, and the countercurrent movement of water and air in the nozzle 4 contributes to a more intensive formation of a water-air emulsion and the use of the end effect: both removal of CO and saturation 0-2 in the moment of crushing and coalescence of water droplets. This contributes to a more intensive desorption-absorption process. The use of this vacuum-spray head in systems with reduced pressure in front of the head when decarbonizing free carbon dioxide from make-up water at a CHP gives an economic effect of up to 90 thousand rubles. per year in the processing of 9OO t / h of water and the saving of metal ZO-50%. The use of a vacuum-spray head during the deferrization of underground water gives an economic effect of up to 1OO rub. per year when processing 1ooo water. The invention includes a vacuum nozzle head comprising a cone-shaped nozzle tapering in the direction of fluid flow, a cylindrical nozzle attached to its outlet end and a cylindrical nozzle encompassing the nozzle to form an annular chamber, so as to simplify the design spraying efficiency, holes are made at the exit end of the lateral surface of the cylindrical tube.
