Combined jet cavitation nozzle

Abstract

The invention provides a combined jet cavitation generating nozzle. The nozzle comprises a shell body, a high-pressure shunt chamber, a low-pressure chamber, a mixing chamber and a nozzle. The shell body is provided with the low-pressure chamber and the mixing chamber which are connected with each other, and the low-pressure chamber is connected with low-pressure fluid. The low-pressure chamber isprovided with a high-pressure shunt chamber which is not connected with the low-pressure chamber. The high-pressure shunt chamber is connected with high-pressure fluid, A plurality of staggered nozzles are arranged high-pressure shunt chamber, and the nozzles pass through the low-pressure chamber and enter into the mixing chamber for shear mixing of low-speed fluid and high-speed fluid. The high-pressure fluid enters into the high-pressure shunt chamber through the inlet pipe, and uses a plurality of misaligned nozzles for high-speed fluid injection after the diversion, so as to solve the problem of mutual interference of outlet fluids when multiple nozzles are sprayed in parallel.

Description

technical field [0001] The invention relates to the field of cavitation or the field of cavitation decontamination, in particular to a combined jet cavitation generating nozzle. Background technique [0002] Cavitation refers to the process of the formation, development and collapse of vapor bubbles inside the liquid or on the liquid-solid interface when the local pressure in the liquid drops below the critical pressure. The cavitation phenomenon will lead to the performance degradation of hydraulic mechanical equipment, causing vibration, noise and cavitation damage. 2 o 2 , O 3 And the -OH in the free state, if this feature is used to strengthen the chemical and physical processes, it will achieve the effects of increasing efficiency, saving energy, and reducing consumption. If it is applied in the field of sewage degradation treatment, better economic benefits can be produced. [0003] Jet cavitation is a way to produce cavitation effects. It is through the conditions...
