Description of the Invention: [Technical Field] The present invention relates to a liquid atomizing device' and can be used for a fire extinguishing system, a sanitary engineering, a device for burning a liquid fuel, an irrigation device, and the like. [Prior Art] It is known that a prior art atomizer comprises a sleeve having a plurality of liquid flow forming channels and a connecting tube for supplying a liquid, wherein the axes of the respective pairs are configured to flow Mutual impact and combination to produce a single-cone of a mist I-spray, and a minimum displacement from the central axis of the atomizer (see US Patent No. 5,044,562, published on September 3, 1991, ipc F02M) 51/G6). Many of the difficulties experienced by existing devices relate to the loss of substantial kinetic energy during liquid atomization, which is due to the formation of an annular flow. It is also known that the atomizer comprises a sleeve having a plurality of liquid flow forming channels and a connecting tube for supplying a liquid. An exit hole for supplying a liquid passage is provided in an axially symmetrical v-shaped surface. The liquid atomization is provided in prior art devices because the liquid cells collide with each other in a specific spatial region opposite to the outlet hole of the liquid supply channel (see Japanese Patent Publication No. 1-076871, issued March 23, 999 Patent, ipc b〇5b 1/26). The atomizer of the above construction allows the atomized droplet spray to be generated separately due to the collision of the liquid flow, and the feasibility is minimized in minimizing the energy consumption for generating the atomized spray. Most similar to the present inventors is an atomizer comprising a sleeve having a plurality of arcuate passages for the formation of a liquid stream and a connecting tube for supplying a liquid (see 丨994 U.S. Patent No. 5,358,179, published on the 25th, 100959.doc 1251509, 1/26. The "recording line of the hole" intersects the atomizer sleeve & the fine atomized spray is produced in the liquid *Shiya # which is initially generated in the channels. Because in the fog The arcuate passages available in the casing are flowed into the shaped portion of the passage at another angular velocity before the inlet point of the liquid flow, the axis of which intersects in the space outside the atomizer casing. °, due to the flow The increase in the relative flow rate caused by the initial rotation and the corresponding angular velocity of the night machine increase the flow of the liquid into an atomizing gas-droplet effluent. However, regardless of the prior art device There is an advantage of how to 'excessive kinetic energy loss due to the increased hydraulic resistance of the liquid supply passage. The present invention is directed to providing a liquid atomizer, Allowing a finely atomized droplet effluent of a predetermined spatial structure to be produced in the liquid supply line at a flow rate and pressure. The technical result to be achieved is the reduced energy used to generate a fine atomizing gas-droplet effluent Consumption. The technical result is provided by the use of a liquid atomizer comprising a sleeve having a plurality of liquid flow forming channels U for: - a liquid connection tube. According to the invention, the liquid flow forms a passage The system, the second mode is extended such that the skewed axial line intersects downstream of the exit section of the (four) track in the formation space region of the atomizing spray. The minimum distance between one of the skewed axial lines of the channel is not Exceeding the average hydraulic radius of one of the channel sections.

It should be noted that Figure 4 reveals the velocity of the flow S1, s2 V1, v2, which respectively have a normal component Vni, Vn2 extending perpendicular to the plane Located in the plane of the drawing: line direction components ντ1, ντ2. • In the collision area of the liquid streams S1 and S2, a vortex forming zone is generated by the action of the velocity in the tangential direction S ντ1, V: 2 (Fig. 4). In the middle of the circular arrow, the liquid flow is decomposed violently, thus producing a fine atomized gas droplet spray. In the vortex forming zone, the liquid flow is trapped in the turbulent flow and at an angular velocity ω and a linear velocity V r rotation. When the liquid flows Si, S2 are close to each other and carry away The vortex forming zone is enlarged when the liquid flow in the process of the outlet section of the channel 2. The axial displacement of the vortex forming zone is performed at a velocity Vn, that is, the rate of generation of droplets in the flow collision zone (see Fig. 4). 5) The angular velocity ω of the flow of the liquid in the vortex formation zone of the flow collision center can be estimated. The flow velocity in the flow collision zone is several meters per second. Up to several tens of meters. The axial displacement of the axial flow of the flow is 1 mm and less. It is expected that the flow of the axial line at a distance of not more than 80 Rg from the exit section of the passage relative to the passage Κ!, & The displacement of the axial line of s! and S2 is not obvious. Depending on the given parameters, the vortex rotation rate in an atomized ejected material generation zone can range from a few revolutions per second to hundreds of thousands of revolutions. Due to a centrifugal force, the generated high velocity vortex decomposes the colliding stream. As a result, the thin liquid film is converted into small droplets. The distance between the exit section of the passage and the area of the intersecting oblique axial line of the passage K and the intersecting axial line at which the atomized liquid ejecting material is to be produced is preferably not exceeded. (10) times the average hydraulic radius of the channels. This is because at a large distance from the exit section of the passage, the flow Sl S2 expands and its flow path is offset by the accompanying kinetic energy loss. The impact force of the intersecting liquid stream is combined with the centrifugal force of the generated vortex to provide a uniform droplet ejection of the fine atomized liquid in the region where the atomized liquid is sprayed. In addition, the centrifugal force allows smaller droplets to be produced at lower pressure differentials. The collision of the liquid stream produces a spatially uniform droplet ejection. Therefore, at the initial kinetic energy of the equal liquid flow, the efficiency of the liquid atomization process is increased continuously, and the uniformity of the empty gate of the fine atomized liquid droplet discharge is improved by using the present invention. . The minimum distance between the axial line 4 of the field channel 2 (Κι, K: 2) and the axial line of the liquid flow &, & (see Figure 4) does not exceed the average hydraulic radius Rg of the channel 2, respectively. The above effects are presented in all measurements. The dependence of the text should be the greater the distance between the axial lines of the test channel and the vortex rotation 100959.doc 13 1251509 The smaller the angular velocity ω, the effect of the liquid atomization caused by the centrifugal force is Presented to a lesser extent. It should also be borne in mind that an increase in the number of channels 2 results in a more uniform spray of atomized liquid droplets due to the full force of the flow impinging on the centrifugal force of the vortex. However, for the effect of liquid atomization caused by centrifugal force, there is a continuous limit on the number of channels, which is present in all measurements: in the preferred embodiment of the liquid atomizer, the number of channels should not exceed six . Has a range of 1 to 179. The use of a liquid nebulizer projected before the skewed axial line 4 of channel 2 in the range of 3 (see Figures 5 to 7) allows the liquid spray to achieve a variety of cone angles and various surface spray intensities . In one embodiment in which the cross-sectional area of one of the channels 2 exceeds that of the other channels 2, a finely atomized droplet ejection having a divergent atomized liquid spray relative to the axis of symmetry 7 of the sleeve 1 is produced. Produce. However, the cross-sectional area of one of the channels should not exceed twice that of the other channels. In the case where there is a difference in the cross-sectional area of the channel 2, the given limit is attributed to the reduction of the liquid flow bifurcation because the substantial difference in the cross-sectional area of the channel causes the atomic process of the centrifugal force to be substantially reduced. . The loss of liquid flow energy due to a frictional force limits the length of the channel 2 to 20 times its diameter. Increasing the length of the channel means that the pressure difference in one of the channels 2 defining the kinetic energy value is reduced and, as a result, the flow rate from the channel 2 is reduced. The distance between the exit section of the channel and the boundary 10 of the spatial region where an atomized liquid effluent is to be produced (see the figure selected under the condition that the liquid maneuvering energy loss associated with a medium resistance is at a minimum. When the flow draws a large kinetic energy (velocity) close to the impact zone, it will provide a more complete score of 100959.doc -14 - 1251509 flow 'this distance should not exceed 80 feet. g The maximum uniformity of a drop of spray Provided that the exit aperture of the channel 2 is equidistant from the axis of symmetry 7 of the sleeve 1. In this example, the flow system rushes into each other in a single focal plane extending perpendicular to the axis of symmetry 7 of the sleeve i. The displacement of the outlet hole of the passage 2 relative to the equidistant position allows the generation of atomized droplet discharges of a plurality of spatial structures. The atomization effect of accumulating the atomization flow and increasing the liquid flow in a predetermined space area The litter is provided with a chamber 9 located downstream of the exit section of the passage 2 (> see Figure 3). In the example of the atomizer embodiment shown in Figure 3, the chamber is a main cylindrical shape. When the liquid in channel 2 flows, a low pressure is because The flow discharge effect is generated in the outlet section. During the flow of the liquid μ through the passage 2, a countercurrent flow is formed in the chamber 9 due to the inflow of gas from the surrounding medium, and the gastric flow contributes to the flow. Liquid atomization process. The length LK is increased to a value exceeding 20 DK (where DK is the diameter of the circular shape chamber 9) causing the effect to be reduced under the action of friction - in the given example of the atomization embodiment The optimum ruler of the chamber 9 is based on the material ratio Dk/Lk=1.7. Another reduction in the hydraulic loss of the good size liquid is attributed to the inlet and outlet of the channel 2 and the generation line of the tapered surface. , 6 extends parallel to and perpendicular to the axial line 4 of the channel 2. The cone angle of the atomized liquid effluent can be varied by using a tactical sleeve having a symmetry axis relative to the atomizer The taper surface of 7 forms a non-fourth oblique angle of the line 6. The cone angle of the atomized liquid ejecting material can also be changed and intersected by acting on the generated area of the atomized liquid ejecting material, that is, the area The liquid flow collides with each other, or the effect is on a production of 100959.doc 1251509 The axial passage 8 of the tube 1 is shown in Figures 1 to 3). In the region where the axial flow is generated (refer to the liquid atomizer shown in the fine atomized droplet discharge device), it is connected to the hole of the connecting tube sleeve 15 of the liquid supply line.

In consideration of the use of the tapered population portion 8 in the embodiment of the atomizer structure, the hydraulic loss at the channel = port can be reduced, thereby increasing the flow rate of the liquid stream. The intersecting oblique axial lines of the channels 12 in the dry perimeter intersect at a 179 degree angle. Since the axial line 11 of the passage p in the embodiment of the atomizer of the consideration is different from the distance of -1, only the peripheral portion of the flow in the area where the atomized liquid is ejected will mutually Shock. As a result, the vortex structure occurs in the impact region of the liquid flow (i.e., the region in which the atomized liquid is ejected), which is similar to the embodiment of the atomizer shown in Figs. The vortex generated by an angular rotational speed can provide decomposition of the liquid flow by centrifugal force, thereby converting the liquid stream into droplets. The tapered shape of the surface of the outlet section of the channel 丨2 in a given embodiment of the atomizer structure provides for the liquid flow to impact each other near the exit section of the passage 12. In this region, the kinetic energy (speed) of the liquid flow is very close to the maximum value to facilitate a more complete decomposition of the liquid stream in the region where the atomized spray is generated. Furthermore, the tapered surface of the exit section of the 5H channel defines a hole in the cylindrical sleeve 14 where the liquid flow impinges upon each other and the vortex forming zone is created. 100959.doc -16- 1251509 The interaction between the faces contributes to the accumulation of droplets and a fine atomization structure that requires the atomized liquid stream and the cone of the sleeve 14 to be in a particular spatial region.
