Abstract

Изобретение относитс к электрофизическим и электрохимическим методам обработки . Цель изобретени - обеспечение стабильности приготовлени газожидкостной смеси при измен ющемс давлении и расходе жидкости. Устройство содержит камеру 1 смешени , сопло 2, выполенное в виде патрубка с фланцами и внутренней полостью со стороны входа жидкости в форме конфузора, а со стороны выхода - в форме диффузора со ступенью и острой кромкой по линии их перехода. Под ступенью по окружности равномерно выполнены всасывающие отверсти . Сопло 2 установлено по центру камеры 1 на упругих диафрагмах 3, закрепленных на фланцах, и имеет возможность перемещени вдоль оси камеры 1 смешени от давлени жидкости. Наружные стенки сопла и диафрагмы образуют в камере смешени герметичную от попадани жидкости полость. В центре внутренней полости сопла 2 установлен рассекатель 4, который закреплен неподвижно на камере 1 имеет форму ступенчато-конического центра и установлен с возможностью регулировки его положени относительно сопла 2 вдоль продольной оси. Рассекатель 4 имеет коническую поверхность со стороны выхода жидкости из сопла 2, сопр гаемую с поверхностью конфузора. 1 з.п.ф-лы, 3 ил. (Л СThis invention relates to electrophysical and electrochemical processing methods. The purpose of the invention is to ensure the stability of the preparation of a gas-liquid mixture under varying pressure and fluid flow. The device contains a mixing chamber 1, a nozzle 2 made in the form of a pipe with flanges and an internal cavity from the liquid inlet in the form of confuser, and from the output in the form of a diffuser with a step and a sharp edge along the line of their transition. Under the step circumferentially, the suction inlets are uniformly made. The nozzle 2 is mounted in the center of the chamber 1 on elastic diaphragms 3 attached to the flanges, and has the ability to move along the axis of the mixing chamber 1 from the fluid pressure. The outer walls of the nozzle and the diaphragm form an airtight cavity in the mixing chamber. In the center of the inner cavity of the nozzle 2, a divider 4 is installed, which is fixed fixedly on the chamber 1 has the shape of a stepped-conical center and is installed with the possibility of adjusting its position relative to the nozzle 2 along the longitudinal axis. The divider 4 has a conical surface on the liquid outlet side of the nozzle 2, which mates with the confuser surface. 1 hp ff, 3 ill. (Ls

Claims

Claim

1. A device for producing a gas-liquid mixture for electrochemical processing, consisting of a mixing chamber with nozzles for gas and liquid inlet and outlet, and having openings for suctioning gas, nozzles located inside the mixing chamber, characterized in that. in order to expand technological capabilities by self-regulating the nozzle orifice, the nozzle is made in the form of a confuser on the liquid inlet side and in the form of a diffuser on the liquid outlet side. and the line of transition of the confuser to the diffuser forms a step with a sharp edge, while in the transition section of the confuser to the diffuser, the diameter of the confuser is larger than the diameter of the diffuser, between which holes are made that absorb gas, the nozzle is installed in the center of the mixing chamber on elastic diaphragms, and into the device, a divider made in the form of a step-conical center, fixed motionless on the housing of the mixing chamber. ·

2. The device pop. 1, characterized in that. that the divider is installed with the ability to adjust its positions along the axis of the nozzle.
