Description of the invention: [Technical field to which the invention pertains] The present invention relates to a pollutant discharge device, and more particularly to a method for utilizing the principle of gas dynamics to form an oblique air curtain above a platform to exclude Encloses the contaminant between the inclined single air curtain and the wall, and enhances the ability to resist the surrounding airflow. 'Applicable to kitchen hoods, restaurant kitchens, laboratories, dust workshops and other operations that generate polluting gases. place. [Prior Art] For users working in general restaurant kitchens, laboratories, dust-operated workshops or other workplaces that generate polluting gases, the dissipation of soot or toxic gases will not only cause environmental pollution, but will also be invisible. Inflicts damage on the human body. Taking the conventional conventional range hood as an example, its structure and configuration are substantially as shown in Fig. 12. The hood is fixed below the upper air duct cabinet 15, and the rear end is opposite the side wall 14' side. There may be a wall 13 at the distance, and the side of the air duct 15 usually has an upper aspect π. The bottom of the range hood 10 is equipped with a draft fan η, which is sucked up by the exhaust fan, and the toxic gas is sucked up on the stage, and is read by installing the air duct 12 on the exhaust hood U). To the outdoors. The range hood (1), the upper air duct cabinet 15 and the lower section of the upper side 16 are the conditioning station 17, on which the furnace table 18 is placed directly under the hood, and the furnace has a gas spring 19 or an electric furnace. Induction cooker. Below the conditioning station 17, a lower cabinet 20 is generally provided. The above-mentioned conventional range hoods are not much different from the top suction hoods generally used in the workplace. The range of effective use of such a smoke extractor or exhaust hood = approximately U times (or shorter) under the suction port, as shown in Figure 13, is not shown below this, the speed of the fluid upwards Already the cake is small, the suction 3 201013124 is not enough, and it is very vulnerable to the influence of people walking, fan blowing, air-conditioning operation, and the sneak _ side thief flow. If there is side interference airflow, the surrounding flow field of the hood or top suction hood will usually become as shown in Figure 14. When this condition occurs, the effective capture zone will shrink to a small range divided by a dividing streamline as shown in Figure 14; the ratio of crosswind speed to inspiratory velocity The larger the 'effective capture area, the smaller it will shrink. Contaminants will therefore shout with the disturbing airflow', causing the kitchen walls to be easy for lion scales, often cooked in the kitchen. ◎ The housewife (especially 疋), the 隹 隹 较多 、 、 , , , , , , , , , , Being threatened and so on. Because there is space left on the top of the stove for the operation of the bridge, the position of the screen of the recorder is not very low. The kitchen may have more people walking, fan blowing, air-conditioning operation, door and window opening and closing, etc. Therefore, the traditional way of using a top suction hood is obviously not suitable for the removal of kitchen fumes and sweat stains. However, as shown in Figure I5, it is a product that is improved on the conventional type of range hood. The suction device of this design maintains the conventional conventional range hood, and the other externally adjusts the left side of the table. , right and front three sides are installed - put horizontal _ 21 (or long popular air trough) 'toss the work up, together with the rear wall 14, the traditional type of excursing air-curtain device» The efficiency of the traditional type of range hood in improving the catching efficiency of the undisturbed airflow is 'but because of the relationship between the jet and the solid wall, when the range hood is pumping, the scales under the hood will appear. Insufficiency (this is the ten dynamics of the basic principles of gas dynamics (four) coffee swirling _ Weitai do three-dimensional _ lining. The long-term average flow field at this time seems to show a stable pair and stagnation point, but the actual The situation has evolved over time. The situation is very high. Moreover, because the suction method used in the 4 201013124 method is still the “large-area pumping-rolling” strategy of the original conventional range hood, it is difficult. Pushing a long distance for rolling The effect, and the spray-flow is easily broken by diffusion; physically, this design does not conform to the principle of "push-pull air curtain", and it is impossible to form an "air curtain" with isolation and emission effects. Two questions: (1) The soot and pollutants are surrounded by the walls of the gas wall and move with the swirling fluid near the stove, so that the time spent in the surrounding area will be much longer (residence time) If smoke is placed near the stove, it can be seen that the smoke above the stove and the compartment are not easily sucked away by the upper hood. When the side interferes with the airflow side, the fumes and pollutants are dissipated; 2) Because the fluid vortex on the stove surrounds the furnace, it will cause the phenomenon of fire and fiber, and cause the combustion efficiency to decrease. As mentioned above, because of the (four) flow field type _ _ _ _ ly hood has easy Lin The problem is that the poor flow field is difficult due to the basic hydrodynamic characteristics. Therefore, if the nucleus of the nucleus is improved, the effect is not easy to highlight. To solve this problem, the present invention provides a different kind of Conventional use The traditional % oil-based design, gj conforms to the principle of gas-mechanism, and has been proved by experiments to be very good. [The invention] The main purpose of the present invention is to provide a pollutant discharge device by means of a platform- The side ax has a long-shaped blowing end' and a long-shaped lower end structure is arranged in parallel on the obliquely upper end of the long blowing end, and the 俾 can form an oblique air curtain to exclude the surrounding single-secret and the wall Between the fumes or harmful nuisances, reducing the dissipation of contaminants and enhancing the ability to resist ambient disturbances. The secondary object of the present invention is to provide an oblique single-air curtain hood with 5 201013124 0

As shown in Fig. 1A, if a jet 5 is ejected from the left to the right by a nozzle 51, the spray is entrained. The surrounding fluid will gradually expand as the distance to the downstream increases. The method of expansion depends on the Reynolds number (Rey_s numbe (10) range. After squirting about 8G, such as diameter _ total amount, then 100~150 After the diameter of the nozzle is gradually increased, the phenomenon of dissipating gradually becomes apparent. During the process of the evolution of the jet 50, the fluid flowing in the jet 5 and the fluid in the external environment continuously exchange momentum, mass and heat. As shown in Fig. 1B, - the suction port 53 is inhaled from left to right' then the ambient fluid in the vicinity of the suction port 53 will assume the appearance as shown at 52' and its more effective range is only about 1.5 below the suction port 53.

In addition, the left and right sides of the table top 77 are deliberately left blank, so that the air can be deflated by the air curtains on both sides as the air supply, so that the flow field between the rolling curtain and the wall 82 can be stabilized without In order to cause unsteady three-dimensional reversal, the left and right sides of the table top 77 may be provided with a flat plate or a grille with holes. Thereby, the fire can be stabilized and not easily fluttered, and the inclined single air curtain and the wall are The % soot between 82 can be stably taken up by the airflow to the upper suction hood 70, and discharged by the long suction end 81 to effectively remove and block the fumes and harmful gases. The gas method (du acer gas me^〇(j) simulates the effect of the invention on the removal of contaminants. The suction hood is installed at a different distance from the conditioning station' in front of the furnace table with an upright large board. Interference airflow swept back and forth 35m/s When simulating a person's walking or fan or cold air gust, the sulfur hexafluoride (SF6) gas is released at a certain flow rate and concentration through a gas release device installed on the stove, and then the upper suction hood pipe is measured far. At the end of the sulphur hexafluoride concentration and flow rate, the capture efficiency can be calculated, that is, the SF-product accumulated per unit time of 201013124 unit time measured by the far end of the suction hood pipe is divided by the gas release device. The 6-volume of the certificate is released per unit time. The result is shown in Figure 8. Obviously, the capture efficiency of the inclined single-air curtain type hood is far more efficient than that of the traditional top-loading range hood. It is much higher and has a much stronger ability to resist the interference of airflow. In the implementation, the rear side of the burner head 79 on the table top 77 is located between the long blowing end 80 and the step 82, and another long blow can be set. The gas end is 8 〇, (as shown in Fig. 9), so that the two long-shaped blowing ends (10), 8〇, are arranged in parallel on the front and rear sides of the furnace head 79 of the table junction β 77, respectively for upward A jet of air is ejected. Referring to FIGS. 10 and 11 , 'the oil collecting device 9 and the oil collecting device 9 are mounted on the suction end 81 '. FIG. 3 is installed by the oil collecting device 9 to prevent adhesion to the suction end 81 The liquid oil on the inner wall drops and is easily removed for cleaning. In practice, the gas end 81 is a rectangular tube that protrudes downward from the flange 71 and has a downward opening, and the oil collecting device 9 is a rectangular box with a σ upper, including a bottom plate 91 and parallel a first side panel %, a first vertical panel 93, a second vertical panel 94 and a second side panel 95 on the bottom plate 91, the bottom plate 91 is provided with a filter a first oil storage space 97 is formed between the side plate 92, the first vertical plate 93 and the bottom plate, and a second oil storage space 98 is formed between the second vertical plate 94, the second side plate% and the bottom plate. The filter 96 is provided with two auxiliary bars 99. The two sides of the one of the auxiliary bars 99 are respectively connected to the first vertical plate 93 and the second vertical plate 94 to form a selection. Thereby, when the oil collecting device 9 is pressed upward to engage the first and second side plates (92, 95) to the outside of the pumping end 81, the soot can be passed through the screen 96 to enter the pumping end 81. After that, the inner wall of the pumping end 81 is condensed into liquid oil, and is dropped into the first and first oil storage spaces (97, 98) along the inner σ to achieve the purpose of oil collecting. From the above description, it will be apparent to those skilled in the art that the product can indeed achieve the aforementioned objectives of 201013124, and has already met the requirements of the Patent Law and filed a patent application. However, the above description is only the preferred embodiment of the product, and the scope of the present invention cannot be limited thereto. Therefore, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the creation manual should remain within the scope of this patent.
