Referring to Figures 2A and 2B, there are shown schematic cross-sectional views of a gas-liquid mixing nozzle device according to another embodiment of the present invention, and a cross-sectional view taken along line 2B-2B of Figure 2A. In the embodiments of FIGS. 2A and 2B, the changes in the structures of the gas-liquid mixing nozzle device 10a and the relative relationship between the structures are similar to the gas-liquid hybrid type shown in FIGS. 1A and 1B. The change of each structure in the nozzle device 100 and the relative relationship between the respective structures are not described herein again, and only the differences will be described below. In the gas-liquid mixing nozzle device 10a, a throttle element 110 is used instead of the throttle element 106 which is substantially a columnar body in the gas-liquid mixing nozzle device 100.

The liquid system in the liquid recess 400 enters the gas-liquid mixing recess 500 via the flow path formed by the first passage 11b and the second passage 110c. In addition, a plurality of the above-described gas-liquid mixing nozzle device 100 or gas-liquid mixing nozzle device 10a are vertically arranged, and the gas-liquid mixing nozzle device 100 or the gas-liquid mixing nozzle device 100a is connected in parallel to The same gas supply source and the same liquid supply source can effectively suppress the uneven distribution of liquid flow caused by the hydrostatic difference, and the principle is explained as follows. Considering the case where the liquid passes through a small-aperture flow path (such as the small-aperture flow path in which the first portion 402 shown in FIGS. 1A and 2A is joined to the gas-liquid mixing recess 500), the energy conservation before and after the liquid passes through the small-aperture flow path , expressed in mathematical form as follows: p y2 U η---1---η gz + M + Q = Constant........................ ...........(1) Ρ _2 where U is internal energy, f is pressure energy, ^ is kinetic energy, gz is potential energy, ρ 2β

Therefore, the above formula (3) can be adjusted as follows: C=-^AP....... ............................(4) 乂p According to the above formula (4), when the small-aperture flow path is cut The smaller the area, the larger the pressure difference ΔΡ is required to maintain the same flow rate. In addition, the smaller the cross-sectional area of the small-aperture flow path, the smaller the flow rate change β caused by the variation of the pressure difference ΔΡ. The principle, when the plurality of gas-liquid mixing nozzle devices 100 or the gas-liquid mixing nozzle device 10a are vertically arranged as described above, by means of the throttling element 106 or the throttling element 110 The cross-sectional area of the first portion 402 is reduced to reduce the flow variation caused by the hydrostatic difference between the plurality of gas-liquid mixing nozzle devices 100 or the gas-liquid mixing nozzle device 100a. Therefore, the plurality of gas-liquid mixing nozzle devices 100 can be Or the variation of the overall flow distribution of the system composed of the gas-liquid mixing nozzle device l〇〇a is controlled within an acceptable range. ^ The following is a practical example and comparison. For comparison, the effect of the above principle is more specifically explained. Comparative Example First, twelve gas-liquid mixing nozzle devices are vertically arranged and numbered, and the height distribution of the twelve gas-liquid hybrid nozzle devices is first. And the corresponding hydrostatic difference system is shown in Table 1 below, wherein the height and hydrostatic difference are based on the gas-liquid mixing nozzle device No. 12. __表一__ Nozzle number relative height hydrostatic difference 11 201233446 [mm (mm)] [million kPa] 1 1986 0.0195 2 1768 0.0173 3 1557 0.0153 4 1353 0.0133 5 1157 0.0113 6 968 0.0095 7 782 0.0077 8 609 0.0060 9 445 0.0044 10 288 0.0028 11 140 0.0014 12 0 0.0000 In this comparative example, the structure of the gas-liquid hybrid nozzle is similar to that shown in Figures Β and 1Β, with the difference that it does not include the throttle element φ 106, and the first portion 402 of the first figure is shown. The aperture of the small-aperture flow path engaged with the gas-liquid mixing recess 500 is 6.6 mm. The twelve gas-liquid hybrid nozzles are connected in parallel to the same gas supply source and the same The body supply source is then applied to the twelve gas-liquid mixing nozzles with six different total liquid flows, wherein the total liquid flow is 25 liters/min (Ι/min), 37 Ι/min, 50 Ι/min, 75 Ι/min, 100 Ι/min and 125 1/min. When the total flow rate of different liquids is applied, the corresponding water flow rate of each gas-liquid mixing nozzle device is recorded as shown in Fig. 3. According to Fig. 3, the water flow rate of the gas-liquid mixing nozzle device 12 201233446 which is closer to the upper side is smaller. In addition, the lower the total flow rate, the greater the relative difference between the plurality of gas-liquid hybrid nozzle devices. Furthermore, when the total flow rate drops to 25 l/min and 37 l/min, there are four and two gas-liquid mixing nozzle devices that cannot eject liquid. Embodiment 1 In the first embodiment, the relevant experimental conditions are the same as those in the above comparative example, wherein the difference is that the gas-liquid mixing nozzle device of the first embodiment adopts the structure as shown in FIGS. 1A and 1B. That is, the throttling element | 106 is included. Further, the throttle element 106 is a columnar body having a diameter of 5 mm. The experimental results are recorded in Fig. 4. As can be seen from Fig. 4, the water flow distribution uniformity of the plurality of gas-liquid hybrid nozzle devices is significantly superior to the above comparative example in which the throttle element 106 is not provided. However, when the total flow rate drops to 25 l/min, there are still two gas-liquid hybrid nozzle devices that cannot eject liquid. Embodiment 2 In the second embodiment, the relevant experimental conditions used are the same as those of the above comparative example φ, wherein the difference is that the gas-liquid mixing nozzle device of the second embodiment adopts the structure as shown in FIGS. 2A and 2B. That is, the throttling element 110 is included, and the throttling element 110 is a throttling tube, and the first channel 11 Ob of the throttling tube has an aperture of 4 mm. The experimental results are recorded in Figure 5. According to Figs. 4 and 5, the water flow distribution uniformity of the plurality of gas-liquid hybrid nozzle devices is similar to the water flow distribution uniformity of the first embodiment. Embodiment 3 In the third embodiment, the relevant experimental conditions are the same as those of the above-mentioned comparative example 201233446, wherein the difference is that the gas-liquid mixing nozzle device of the third embodiment adopts the structure as shown in FIGS. 2A and 2B. That is, the throttling element 110 is included, and the throttling element 110 is a throttling tube, and the first channel 11 Ob of the throttling tube has a hole diameter of 3 mm. The experimental results are recorded in Figure 6. According to Figures 4, 5 and 6, it can be seen that the water flow distribution uniformity of the third embodiment is further improved compared to the water flow distribution uniformity of the plurality of gas-liquid mixing nozzle devices shown in Figs. 4 and 5. . Even when the total flow rate drops to 25 Ι/min, the gas-liquid mixing nozzle unit located at the upper No. 1 and 2 can eject the liquid.
