漸產生明顯的消散現象。在噴流50演化的過程，喷流5〇的流體與外 鲁界環境的流體不斷進行動量、質量、與熱量的交換。如第1β圖所示， 顯示有一抽吸口 53由左往右吸氣，則在抽吸口 53附近的環境流體將 呈現如52所示的樣貌，且其較有效用的範圍僅在抽吸口幻下游大約 .K5倍(或更短)抽吸口 53直徑以内；而如第1C圖所示，當—個喷流5〇 •與一個抽吸口 53安置在相對的位置，且相隔一段距離，則隨著喷I與

other workplaces that produce smudgy gas, the escape of soot or toxic gases will not only cause environmental pollution, but will also be invisible. The human body causes damage. Take the traditional type of range hood as an example. Its structure and configuration are roughly as shown in Fig. 12. 4' row of hoods 1G is located below the upper air duct cabinet 15, and the rear end is opposite the rear wall ^ side - There may be a wall 13 at the distance, and there is usually an upper bridge = next to the air duct cabinet 15. The bottom of the range hood H) is equipped with a suction fan n, which is used to suck up the furnace σ or toxic gas, and is installed outdoors on the top of the inspection machine (1). The lower-section distance between the 1G and the upper air duct cabinet and the top view is the conditioning station 17, on which the stove 18 is placed directly below the range hood '. The gas stove has a gas burner 19 or an electric furnace. Induction cooker. The conditioning console has a lower cabinet 20. The slave h-type range hood and the top suction hood used in the workplace (_ below the Z 1 . This hood or the reduction of the effect of the franchise _ in the suction port,,,, ... or shorter Within the diameter of the suction port, as shown in the scope of Figure 13, she is _ thin, and the force of 1341916 is affected by side interference airflow from people walking, fan blowing, air-conditioning operation, door and window opening and closing. If there is side interference airflow, the surrounding flow field of a conventional range hood or top suction hood will generally become as shown in Figure 14. When this happens, the effective capture zone will shrink to a small range divided by a dividing streamiine as shown in Figure 14; the ratio of the crosswind speed to the inspiratory velocity The larger the effective capture area, the smaller it will shrink. > Wan Dystuffs will therefore dissipate with the interference of airflow, resulting in the kitchen wall is easy to accumulate grease, the housewife who often cooks in the kitchen (especially the cooking method is more fried, the fire of the Chinese housewife) And so on. Because the space above the stove needs to be left for the operation of the cabinet, the installation position of the hood is lowered, and the kitchen is more or less with people walking, fan blowing, air-conditioning operation, door and window opening and closing, etc. Factors, so the traditional way to make the _ wire hood is the same as the removal of the oil shaft _. . As shown in Figure 15, 'it is a product that is improved on the traditional type of range hoods'. The traditional lion hood of this design is reduced to the county, and the other is in the conditioning machine (four) left, right, top three Installed on each side - the cross-flow fan 21 (or a long blow, blowing the air up, together with the rear wall 14, surrounds the traditional type f with the space under the hood (embi^ingaiKurtain-ee). Although the design can improve the capture efficiency of the conventional traditional range hood in the interference-free airflow, because the four-way flow, the solid surface is _ system, when the range hood is pumping, the flow field under the smoke machine will It is financial (this riding _ mechanics, this Gu--), the second, the mining (10) Weitai to do three-dimensional Saki Wei. At this time, the long-term distraction field sees the two stable and stagnation points. However, in fact, the "large-scale pumping" strategy of the county-style hood is difficult to manufacture for the airflow == _ pull effect' (four) exhausted _ broken; _ lion heart 6 1341916 • does not meet the "push-pull air curtain" The principle of 'can't form a gas curtain with isolation and emission effect. Therefore, it will be produced The next two problems: (1) the soot and pollutants are surrounded by the gas wall and the solid body wall and move with the vortex of the fluid tumbling near the stove, so that the time of residence in the package (residence time) It will be much longer (if you put smoke near the stove, you can see the smoke on the top of the stove and the surrounding it is not easily sucked away by the top hood). When it is affected by the side interference airflow, these soots and pollutants Easy to dissipate; (2) Because the fluid vortex on the stove surrounds the furnace, it will cause the flame to flutter and cause the combustion efficiency to decrease. Therefore, the dynamic leakage is a traditional type of range hood and based on its structure (such as The challenge faced by the improved product (as shown in Figure 4). As mentioned above, 'the problem of the easy-to-leakage of the traditional type of range hood due to the poor flow field type' and such a bad flow field The type is caused by the basic hydrodynamic characteristics. Therefore, if the traditional basic structure (such as Figure 1) is improved, the effect is not easy to highlight. To solve this problem, the present invention provides a different form of learning. The design of the conventional type range hood is very good because it conforms to the principle of aerodynamics and has been experimentally verified. The main object of the present invention is to provide a pollutant discharge device by means of a platform. The two sides are respectively provided with parallel elongated blowing ends, and a structure of an elongated suction end is arranged in parallel above the two parallel elongated blowing ends, and two air curtains can be formed to exclude the surrounding of the double air curtain. Between soot or harmful gases, reducing the dissipation of contaminants and enhancing the ability to resist the surrounding disturbances. The secondary object of the present invention is to provide a dual air curtain type range hood 'by the front and rear sides of a table top A parallel elongated blowing end is provided and a long suction end is arranged in parallel above the two parallel elongated blowing ends, 俾7 > == the left and right sides of the table top are sucked in as qi The use of the shape of the curtain, in order to reduce the dissipation of soot, reduce the adhesion of the soot after the stove. The soil can make the flow field between W and the last two air curtains stable, which does not make the ~H financial-like stable belt to the cut suction hood and is discharged to effectively remove and block the fumes and harmful gases. The second blow, the hedgehog finds the miscellaneous touch (four) including the first, the 乂 罩 ° ° where 'the first ― two blows the air (4) respectively with the first - ^ and the younger two long blowing end, the first -, two The long blowing end system, before and after the parallel loss discharge port, the upper part _ J 2 is placed above the flat disturbance, and includes at least one elongated sleeve end, and the suction end is connected to a pumping _, And the pumping end is parallel to the first and second elongated blowing ends.

The shape between the gas ends is close to the __ 柏密's low oil _ escaping, and the ability to resist the disturbance of airflow. In order to facilitate the solution of the present invention, the following is described: [Embodiment] 8 1341916 Refer to the 1A~..C diagram for the 'contaminant discharge device of the present invention and 'double air curtain type using the device The basic principle used in the range hood is the "push-pull" phenomenon between the jet and the suction flow on the hydrodynamics. As shown in Fig. 3, if a jet 50 is ejected from left to right by a nozzle 51, the jet 5 will be gradually entrained as the downstream distance increases due to the entraining of the surrounding fluid. The extended method depends on the range of Reynolds numbers. After a momentum conservation phase of approximately 8 喷 nozzle diameter distances downstream of the spout, then a significant dissipating phenomenon is gradually produced after a distance of 100 to 150 spout diameters. In the process of the evolution of the jet 50, the fluid of the jet stream 5 and the fluid of the outer Lujie environment continuously exchange momentum, mass, and heat. As shown in Fig. 1β, it is shown that a suction port 53 is inhaled from left to right, and the environmental fluid in the vicinity of the suction port 53 will exhibit a appearance as shown in Fig. 52, and its effective range is only in pumping. The downstream of the suction nozzle is approximately .K5 times (or shorter) than the diameter of the suction port 53; and as shown in Fig. 1C, when a jet 5〇 is disposed at a position opposite to a suction port 53, and spaced apart For a distance, the flow field between the spout and the suction π 53 will exhibit different patterns depending on the distance between the spray I and the suction port 53, the Reynolds number of the jet 5 以及, and the suction strength. If the above money is adjusted properly, an aircurtain phenomenon can be generated. The air curtain has a certain degree of cohesive strength and can resist the influence of a certain degree of lateral interference airflow. Referring to Figures 2 and 3, which are preferred embodiments of the pollutant discharge device of the present invention, the first and second air blowing devices (6, 6,) and the suction hood 61 are included. among them, . The Haidi popular gas device (6, 6') is respectively provided with a first-shaped air blowing end & and a second long air blowing end 64, and the first and second long-shaped blowing ends (5) and (4) are arranged in parallel to the flat The front and rear sides of the disturbance discharge port 65 are respectively configured to eject the air nozzle flow upward; and the suction pump 61 is disposed above the platform 6", and includes at least one elongated suction end (6). The gas end 6〇 is formed—opening the downward suction port, the suction end is connected to the air extractor (not shown), 9 gas end (63 2) 60 is flushing the gas: another 'the long pumping The end 60 and the first and second elongated blows 62 are respectively extended on the two sides of the elongated suction end 60 with a flanged county 1 and a rear side of each of the two sides of the blowpipe 60 as a first- 2: pumping two ο (Γ上(4). When the first and second long blows (63, 64) are blown up to 60 (4), the platform 6, the scales = two = and almost Two-dimensional air curtains (66, 67). In this case, the existence of the near-square W π lacks the supplementary airflow from below, so in the formation of a recirculation zone, the airflow outside the recirculation zone will be expanded by turbulence = u= d_Gn) No tearing her __峨. On the recirculation zone ==__ on _ The cover 61 is discharged to the outside. On both sides of the flat edge 6, the heart or the slanted plate or grille having the slot is formed to allow the ambient fluid on both sides to be sucked into between the double air curtains to form a qi function. (As shown in Figure 3), the flow field structure shown in the figure is stabilized without dynamic thirst. See Figure 4, which is a double curtain with a pollutant discharge device! The preferred embodiment of the machine includes a first and a second air blowing device (7 air hood 70, the second air blowing device (7, 7,)) has a first long air blowing end and a second long shape. a blowing end 80', the first and second elongated blowing ends (10), the ribs on the front and back sides of the furnace head 77, for the flow of:: respectively; and the suction hood 70 is provided at Above the table top 77, the suction hood % includes: a small "long suction end 81' of the suction end phantom connection - an air extractor 72, and the suction end is illusory ~ two long blow end (10), Parallel.

The side view of the flow field in Figure 7 is no longer like the recirculation in the 5th circle near the furnace. The bubble structure, on the other hand, produces a source point (5〇_ ρ〇^), the velocity of the airflow between the _ below and the top of the table is small, and the influence of the smoldering flame is small 'in the furnace. The rear of the table = the curtain is trapped by the wall The effect is that the flow 'type' which is not completely symmetrical with the front air curtain and the air flow near the rear wall will be generated due to the flow topology and the corner full rotation. However, since the soot is still wrapped between the front and rear air curtains, it is appealed that the flow field change caused by the presence of the back wall does not affect the effect of the facility of the present invention. > In addition, the effect of the removal of the contaminant by this invention was examined using a tracergas method. Install the suction hood at a different distance from the conditioning table, and provide a turbulent airflow of 〇35m/s back and forth in front of the furnace table to simulate a person's walking or fan, cold air gust. The sulphur hexafluoride leaping gas is released through the pneumatic limb release A, which is installed on the stove. The amount of money measured above the upper end of the suction hood pipe 12 1341916 /, fluorination, agricultural degree and flow rate 'can be calculated and captured Efficiency (ea_ee running ency), which is the amount of % volume that the transposition time flows by the far end of the hood pipe divided by the volume of SF6 released by the gas release for the master. The result is shown in the 9th _. It is clear that the capture efficiency of the double-air curtain type range hood is much higher than that of the traditional view range hood, and the ability to resist interference with the airflow is much stronger. Referring to the i-th diagram, the system is a section of the oil collecting device 9 and the oil collecting device is mounted on the reducing end 81, and the |[1] is installed by the oil collecting device 9 to prevent adhesion to the pumping end 81 _ The liquid oil is dripped down and easily removed for cleaning. >
