DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to an emulsifying device, and more particularly to a device for emulsifying high-pressure gas and liquid by cavitation. [Prior Art] The microbubbles released after decompression of air-dissolved water are widely used in water treatment and other procedures. The smaller the bubble, the longer it stays in the water and the greater the effect. The density of the bubbles in the water is emulsified when it reaches the highest • high state. The diameter of the bubbles required for emulsification is less than a few microns. Therefore, how to obtain a bubble having a smaller diameter and a higher density is an important subject of the pressure floating method. The purpose of Taiwan Patent No. 245667 is to provide an "ultra-fine bubble generator" which uses a multi-stage pump to dissolve air in water to generate a gas and liquid, and sends the gas to the decompression device to make the gas and liquid instantaneous. The pressure was reduced and discharged to produce ultrafine bubbles. According to the structural relationship, the bubbles generated by the former patents are limited in size and density, so that the conditions of emulsification are not obtained. SUMMARY OF THE INVENTION According to the inventors, in a high-speed water flow path, when the speed changes, the partial pressure is lower than the evaporation pressure of the water, causing the water to evaporate into a tiny cavitation bubble, which then Internal collapse (c〇丨丨叩) and release can still be awkward. This phenomenon is called "cavitation" in fluid mechanics (flujd mechanjcs). The inventors have further found that when gas and liquid flow through the cavitation zone (cavitation 5 201020023 zone), fine bubbles (such as (10)) are released from the water; and when the cavitation bubble collapses, the air contained therein is decomposed into Small bubbles, while the high energy released by the cavitation bubbles will excite more bubbles from the water, resulting in an emulsification effect. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an emulsifying apparatus which utilizes cavitation in a fluid dynamics to cause an air bubble to form an emulsified state as it can be diffused in water. The emulsification device of the present invention comprises a mixing pump; a water source is connected to the hydrazine mixing pump to supply water to the mixing pump; and a water inlet regulator is connected to the mixing pump to adjust the flow rate of the water into the mixing pump; An air intake regulator, in communication with the mixing pump to regulate the flow of air into the mixing pump, and the mixing pump dissolves the air into the water to output a high pressure gas liquid; and an emulsifier, in communication with the mixing pump, including a housing therein The space is partitioned into a front chamber and a rear chamber by a partition. The partition has a plurality of narrow holes, and when the high-pressure gas and liquid flows through the narrow holes, an emulsified state is formed due to cavitation. In a preferred embodiment, the narrow width of the emulsifier is less than 0.3 mm, such that the area of the milk occupies accounts for more than 20% of the area of the narrow hole. In a preferred embodiment, the emulsifier further comprises a lashing plate movably disposed on one side of the partition plate. The lashing plate has a plurality of slit holes, and the slit hole can be adjusted relative to the partition plate via the movable lash plate The position of the slit allows the gap between the two narrow holes facing each other to be adjusted due to the staggering. In a preferred embodiment, the mixing pump is centrifugal, comprising at least one moving impeller that rotates with its pump shaft, and at least one static impeller fixed to its pump casing, the impeller and the stationary impeller respectively having a disc disposed thereon The multiple channels of the outer edge are for 6 201020023. The technical contents and other objects and features of the present invention will be fully understood from the following detailed description of the accompanying drawings. [Embodiment] In the first drawing, a plane of an emulsifying device 1 is shown, and the technical contents of the present invention can be explained. The emulsifying device 10 comprises a water source 20, a mixed fruit 30, a water inlet regulator 4A, an air intake regulator 5A, a check valve 6A, an emulsifier 70 and the necessary piping. Wherein: the water source 20 is in communication with the mixing pump 30 via a first line 25 to supply water to the pump 3 〇. In order to ensure that the water entering the mixing pump 3 is clean, a filter 21 is provided at the outflow port of the water source 20, so that solid impurities in the water can be filtered to prevent the emulsification passage described later from being clogged. The water inlet regulator 40 is disposed on the first line 25 for adjusting the flow rate of water supplied from the water source 20 to the mixing pump 3〇. The intake regulator 50' is disposed on a second line 45 for regulating the flow of air into the mixing pump 30. The second line 45 communicates with the first line 25' and is located between the water inlet regulator 4A and the mixing pump 3''. The mixing pump 30, in communication with the water source 20, is used to create a low pressure at the inlet, induces water to enter the pump casing, and draws in air to dissolve it into the water to output a saturated gas liquid having a pressure greater than 4_0 kg/cm2. As shown in the second, the mixed sigma pump 30 is of a centrifugal type, but unlike the conventional centrifugal pump, it includes a movable impeller 33 that rotates with its pump shaft 31, and a stationary impeller 34 that is fixed to its pump casing. The disk 35 of the impeller 33 is provided with a plurality of passages 37, and the disk 36 of the impeller 34 is also provided with a plurality of passages 38 for the high-pressure gas to be liquid-cooled. The function of the shaft is over, and the effect is left to be described later. In the embodiment of the drawings, the passages 36 and 38 are circular, and other shapes such as an elongated shape may be employed without being limited by the circular shape. Further, the combination of the movable impeller 33 and the stationary impeller 34 can be duplicated to form a multi-stage mixing pump, and a higher pressure saturated gas liquid can be produced. The check valve 60 is disposed on the second line 45 and located between the first line 25 and the intake regulator 50 to prevent water in the first line from flowing back through the second line 45. Gas regulator 50. The check valve 6 〇 and the air intake φ θ 50 can also be a combined device in parallel. The emulsifier 70 is in communication with the mixing pump 3 via a third line 55. As shown in the fourth figure, the emulsifier 70 includes a housing 71 having an inner space partitioned by a partition 72 into a front chamber 73 and a rear chamber 74, and the partition 72 has a plurality of slits 75, and the slits 75 constitute An emulsification pathway can create cavitation when gas and liquid flow. Since the cavitation action only occurs at the edge of the slot 75, so in order to obtain a higher proportion of cavitation zones, the width a of the slot 75 should be less than 33 mm, so that the cavitation® zone can be occupied. More than 20% of the area of the narrow hole 75. When the emulsifying device 10 is in operation, the mixing pump 30 starts to operate, on the one hand, sucking in the water supplied from the water source 20 via the first line 25, and also sucking in the appropriate amount of air from the intake regulator 50 via the second line 45. . When water and air enter the shell 32 and the impeller 33 rotates together, the energy of the impeller 33 is received to raise the pressure, and the speed is increased, and the air is dissolved in the water to form a high-pressure saturated gas. When the gas-liquid passive impeller 33 is brought to the discharge port 39, the gas-liquid can flow in the axial direction through the passage of the movable impeller 33 and the stationary impeller 34. 20102, 2003, 3, 36 and 38', because the impeller 33 rotates relative to the stationary impeller 34. The resulting shearing action breaks up the bubbles that have not yet been uniform, so that the bubbles can be evenly distributed in the water's time to shorten the time in which the air dissolves in the water. The gas liquid leaving the mixing pump 3 is sent to the front chamber 73 of the emulsifier 70 via the third line 55; when the gas liquid flows through the slit 75 of the emulsifier 70, the emulsification is completed due to cavitation, and then The rear chamber 74 flows out to the sink 80 via a fourth conduit 65 or back to the same water source 20. The fifth figure shows another embodiment of the emulsifier 70a. The emulsifier 7A shown in the present embodiment is provided with a lash plate 76 as compared with the emulsifier 70 described above. The shims 76 are movably disposed on one side of the partition 72 and have a plurality of slits 77. In the present embodiment, the slits 72 and the slits 75 and 77 of the lashing plate 76 are equidistantly disposed while having a width of several mm. Thus, by moving the lashing plate 76, the position of the narrow hole 77 relative to the spacer slot 75 can be adjusted, so that the two narrow holes 75 and 77 facing each other are staggered, or the gap b generated by the same axis can be The adjustment is not limited by the above-mentioned slit width a fixed to suit different fluid conditions, and the gap b can be adjusted to the maximum to discharge solid impurities when the emulsification passage is blocked. Of course, the above embodiments may be modified without departing from the scope of the invention, and all the matters included in the above description and the drawings are to be considered as illustrative and not limiting the scope of the invention. .
