The cavitation bubbles expand and grow along with the flow of the liquid. When the liquid pressure recovers, the cavitation bubbles are instantaneously collapsed to form micro jet and shock waves, and instantaneous local high temperature and instantaneous high pressure are generated. The energy released by the hydrodynamic cavitation phenomenon can also be utilized to realize the strengthening of the processes of chemistry, physics and the like, and achieve the effects of heating, efficiency enhancement, energy conservation and the like.

Detailed Description

Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.

Referring to fig. 1, a perspective view of an embodiment of a hydrodynamic cavitation heating apparatus according to the present invention is shown. The hydraulic cavitation heating equipment comprises a pressurizing device, a heating chamber, a water inlet valve and a water outlet valve, and is used for quickly heating liquid in the equipment.

Specifically, the heating chambers of the hydrodynamic cavitation heating apparatus 100 include at least a first heating chamber 110 and a second heating chamber 120, and the hydrodynamic cavitation heating apparatus 100 further includes a water inlet valve 130, a water outlet valve 140, and a pressure boosting device 160. Wherein the first heating chamber 110 and the second heating chamber 120 are provided in a separated form, as shown in fig. 1

In the first heating chamber 110, a first water sump 111, a first contraction device 112 and a second water sump 113 are included, the first contraction device 112 is arranged between the first water sump 111 and the second water sump 113, and the liquid in the first water sump 111 enters the second water sump 113 from the first contraction device 112 under the driving of extremely high pressure. The inner wall 114 of the second water sump 113 is provided with an irregular surface structure, which may be a convex structure.

As the liquid flows through the first constriction device 112, a pressure drop is created and gas dissolved in the liquid is released. When the pressure is reduced to the saturated vapor pressure of the liquid or even below, a large number of cavitation bubbles are generated due to the violent vaporization of the liquid, and the cavitation bubbles are accompanied by the hydrodynamic cavitation generated under certain hydraulic conditions. Wherein the first constriction device 112 may be implemented using a geometric orifice, a venturi, etc.

In the second heating chamber 120, a third water sump 121, a second contraction device and a fourth water sump 123 are included, the second contraction device is arranged between the third water sump 121 and the fourth water sump 123, and the liquid in the third water sump 121 enters the fourth water sump 123 from the contraction device under the driving of the pressure. The second constriction device may be of similar structural design to the first constriction device 112. The inner wall 124 of the fourth water chamber 123 is provided with an irregular surface structure, which may be a convex structure.

The liquid entering the second water sump 113 from the first contraction device 112 moves with high pressure, and when the liquid directly collides with the inner wall 114 of the second water sump 113, the heating effect of the hydrodynamic cavitation phenomenon is further promoted, so that the heating efficiency is improved.

After the liquid in the second water sump 113 undergoes hydrodynamic cavitation and collides with the inner wall at high pressure, the liquid enters the third water sump 121 through the first water guiding pipe 151 under the pushing of pressure and then undergoes hydrodynamic cavitation again, and since the inner wall 124 of the fourth water sump 123 can also be provided with an irregular surface, the liquid collides with the liquid which enters the fourth water sump 123 and moves at high speed again, the conversion efficiency of heating is further improved.

In some alternative implementations, the pressurizing device 160 may power the entire hydrodynamic cavitation heating apparatus with a motor 161, and the motor 161 may be placed on a placement table 166, as shown in fig. 2. The motor 161 includes a bearing 162, and the motor 161 has an impeller 163 and a pressurizing groove 164 therein. The motor 161 drives the bearing 162 to rotate the impeller 163, so that the water in the fourth water sump 1231 enters the pressurizing tank 164 through the second water guiding pipe 152 along the water flow direction 1520. The impeller 122 rotates at a high speed to pressurize water, and the pressurized water enters the first sump 111 through the third water guide pipe 153 in the water flow direction 1530. Wherein, along the water flow direction 150, water enters the plenum chamber 164 and passes through the plurality of openings 165 therein, where hydrodynamic cavitation is also created, causing the passing water temperature to increase and the molecules to become smaller. A plurality of openings 165 are located between the plenum groove 164 and the impeller 163.

The cavitation phenomenon in the hydrodynamic cavitation heating apparatus 100 may also be continuously circulated in the first heating chamber 110 and the second heating chamber 120 by the pressurizing device 160 until the water temperature reaches the desired temperature. At the same time, cavitation can also increase the water activity.

Fig. 3 shows one possible implementation of the first constriction device 112, using venturi tubes 1120 arranged side by side. Liquid flows in from the inlet pipe of venturi 1120, and because the sectional area reduces at the contraction section of inlet pipe, the liquid velocity of flow accelerates, and liquid pressure reduces, when reacing middle part choke department, throat pressure reduces to liquid saturated steam pressure down, and vapor overflows with the bubble of dissolving in aqueous, and liquid motion is to the choke end after, because liquid pressure fluctuation, partial bubble ulcerate takes place first cavitation. When the liquid continues to move forwards, the pressure of the liquid in the expansion pipe section is increased, and the bubbles are broken to generate strong cavitation. The energy released by the hydrodynamic cavitation phenomenon can also be utilized to realize the heating of the liquid. The shrinking device inside the second heating chamber 120 can also play a role in hydrodynamic cavitation heating.

In some alternative implementations, the arrangement of the first shrinking device 112 and the second shrinking device may not be particularly limited, and may be set according to actual situations.

The hydrodynamic cavitation heating apparatus 100 further includes a water inlet valve 130 and a water outlet valve 140.

In some alternative implementations, the inlet valve 130 is disposed on the first sump 111 and the outlet valve 140 is disposed on the fourth sump.

In some alternative implementations, the outlet valve 140 is provided with a temperature control device that automatically opens when the temperature of the water inside the heating chamber is above 50 °. The heated water can be used in bathtub, SPA and other items.

In some alternative implementations, as shown in fig. 4, the hydrodynamic cavitation heating apparatus 200 includes the first heating chamber 110 and the second heating chamber 120 which are integrally formed, but are spaced apart from each other by the inner wall 114, and communicate with each other through the first water conduit 151. Fig. 5 is a schematic sectional view of the hydrodynamic cavitation heating apparatus 200 in fig. 4. The other structure of the hydrodynamic cavitation heating apparatus 200 is the same as that of the hydrodynamic cavitation heating apparatus 100 in fig. 1.

In some alternative implementations, as shown in fig. 6, the entire exterior of the hydrodynamic cavitation heating apparatus 200 is covered by a sound-proof enclosure 301. The noise of the outside environment caused by the hydrodynamic cavitation heating equipment can be reduced in the using process.
