GENERATOR OF OSCILLATING GAS-LIQUID FLOW Russian patent published in 2000 - IPC

FIELD: surface-cleaning apparatus. SUBSTANCE: generator can be used for cleaning of solid surfaces of various configuration. Made in generator body are units for inflow of gas and liquid, liquid and gas mixing units, and unit for discharge of gas-liquid flow. Additionally introduced in generator is unit with two chambers for formation of oscillating gas-liquid flow. First chamber is connected with liquid and gas mixing chamber. Second chamber is connected to outlet neck of discharge unit and to diffuser in discharge of working oscillating gas-liquid mixture. Correlation of number of main parameters characterizing major design features of generator is optimal. For example, relation of minimal dimension L₁ passing through geometrical center of generator and its maximal dimension L₂ is to be within limits of following expression: 1,05≤(L₁+αL₂)/L₂≤2,6, where α - experimental parameter taken depending on preset frequency of flow oscillation and preset range of working pressure of liquid and gas to be within limits of 0,3≤α≤1,6. Aforesaid embodiment of generator improves quality of washing of parts having complex configuration, and also washing of passages with blind sections. EFFECT: higher efficiency. 1 dwg
