Hydrodynamic super-cavitation apparatus

Abstract

The present invention relates to a hydrodynamic super-cavitation apparatus in which effects of biodiesel production, emulsification, water treatment, descaling, and particle crushing or the like are doubled according to a significant increase in an acting force of an outlet side of the apparatus where a water vapor bubble-type cavitation collapses. The hydrodynamic super-cavitation apparatus according to the present invention comprises: a main body having one side connected to a fluid supply line for supplying fluid, and an interior having a cross-section decreasing space with a gradually decreasing transverse cross-section area, wherein the cross-section decreasing space has one side having a large space communicated to the fluid supply line and the other side having a small space; an outlet cap which is coupled to one end of the main body and which has an interior with one side having a first cross-section increasing space communicated to the small space of the main body and the other side having a second cross-section increasing space which gradually increases the transverse cross-section area beginning from a transverse cross-section area smaller than the first cross-section increasing space; a closing cap coupled to the other end of the main body in order to close the other end of the main body; and a center bar one end of which is supported by and coupled to the closing cap, and which passes through the interior of the main body so as to be extended to the second cross-section increasing space of the outlet cap.

Description

technical field [0001] The invention relates to a hydrodynamic cavitation device, specifically, when a fluid flows through a pipeline including a Venturi portion whose cross-section decreases to increases, due to the pressure difference between the front and rear of the Venturi portion, the water vapor bubbles form Forces are exerted when the vacuoles are created, expanded and ruptured. This force is used in hydrodynamic cavitation devices in the fields of biodiesel production, emulsification, water treatment, descaling, and particle crushing. Background technique [0002] Generally speaking, when the fluid flows through the pipeline including the Venturi part whose cross-section decreases to increases again, the flow velocity slows down and the pressure rises in the part where the cross-section decreases, and the flow speed accelerates in the part where the cross-section increases. The pressure drops. At this time, due to the pressure difference on both sides, many cavita...

Problems solved by technology

[0005] However, for the traditional hydrodynamic cavitation device, only the generation, expansion and rupture of the cavitation in the form of water vapor bubbles are simply used. In fact, the force at the outlet of the cavitation in the form of water vapor bubbles is low.
