Description of the invention (1) The technical field of the C invention printed by the Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Economics] The present invention is clearly described in a two-fluid nozzle, in particular, gas and liquid, or Gas-liquid mixed gas and liquid collide and mix with each other in order to make the granulated gas-liquid sprayer, which is used for high-grade objects or gas (gas) cooling, heavy oil and other combustion. [Conventional technology] K-way, for this two-fluid nozzle, there is an internal mixing method of collision mixing inside the nozzle, and an external mixing method of collision mixing protruding from the position of the nozzle outside. As for the external mixing method, there is a two-fluid nozzle shown in the 11th circle. These two-fluid nozzles supply liquid from the center hole la of the nozzle 1 while supplying air from the hole lb provided in the outer periphery, and make the air A collide with the liquid L outside the injection hole lc. As for the internal mixing method, there are two fluid nozzles shown in Figure 12. This two-flow skull nozzle supplies air A to the central hole 4a of the nozzle body 4, and at the same time supplies liquid "L" from the hole 4b that is open to the outside. In the inner chamber 4c of the nozzle body, the air and liquid collide and mix to mix the gas In this state, the injection is performed from the injection hole 5a of the nozzle tip 5 connected to the nozzle body 4. [Problems to be Solved by the Invention] According to the external mixing method shown in FIG. 11 above, when air and liquid are supplied as designed, if the gas-liquid collision is mixed, although the desired degranulation can be achieved, it is on the air side. It is troublesome to reduce the amount of air or air E. Moreover, if only the liquid jet is sprayed, the liquid becomes a stick flow from the jet port and jets and hits the jetted body. At this time, the liquid pressure is lkg / cm · ~ 8kg / cma (please read the precautions on the back before filling in this page)-Pack * Order. This paper size is applicable to China National Standard (CNS) A4 specification (210X297 mm) 4 313533 Α7 Β7 Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Invention Instructions (2), even if the jetted body is 3m away, there may be damage. In this respect, according to the internal mixing method, only the liquid brewing is also sprayed and diffused from the injection port to a desired angle, so the stick flow does not directly hit the object to be shot and thus does not cause the above-mentioned problems. However, according to this internal mixing method, if the gas-to-water ratio (gas / liquid) is set low, and the amount of supplied air is reduced, there is a problem that the particle size becomes larger. That is, the relationship between the gas-water ratio and the particle size is as shown in the 13th circle. If the gas-water ratio is set to a low value in order to reduce energy, there is a problem that the particle size becomes larger. The present invention is based on the above problem The purpose of the creator is to provide a two-piece mouth-mouthing. M Biandi makes trouble on the air side and only sprays liquid and does not become a stick flow, so that the spray body is not injured, and even if the air-water ratio is Decreasing * will not make the particle size as large as the internal mixing method. In other words, the shortcomings of the external mixing method and the internal mixing method can be eliminated. [Means to solve the problem] In order to achieve the above object, the present invention provides a two-fluid nozzle in item 1 of the scope of the patent application. Its special feature is: a liquid supply path is provided inside the nozzle, and a gas is provided at the outer peripheral position Fang supply channel; on the inner side of the injection port at the front end of the nozzle, a gas flow channel communicating from the gas supply channel to the injection port is provided oppositely, and then M is ejected from a front end of the liquid supply channel. The liquid eluent flows out of the liquid phase of the hole and collides with each other; it causes the gas-liquid mixture facing opposite near the injection port to collide. Since the inside of the nozzle near the injection port, from the outer periphery, the gas is directed towards the liquid smelt that is sniffered from the liquid rollout outlet, and collides in a substantially orthogonal direction,

Description of the invention (3) The body flow path intersects with the gas stream flow path, thereby colliding the liquid with the gas. * The K can reduce the particle size. In this way, the liquid and the gas are collided and mixed near the front of the injection port. Therefore, the particle size can be reduced by reducing the gas-water ratio. Furthermore, near the injection port, the gas-liquid mixture that first collided with the gas ram is collided with each other, so it can be disintegrated into a liquid. The closed barium wall at the front end of the ejection port used to surround the front end of the nozzle is formed as a shielding portion for ejecting the liquid phase from the liquid phase roll-out hole for liquid colliding. (Item 2 of the patent application scope) According to the nozzle constructed as described above, the liquid lead from the liquid supply path to the ejection port collides with the shielding portion of the periphery of the injection port and diffuses, so the gas supplied from the gas supply path There is little or no pith, and there is no liquid turned into a stick rolling from the ejection port. In addition, even if a viscous substance is used as the liquid, the particle size can be reduced by colliding with the shielding portion. In addition, since the gas is directed in a substantially orthogonal direction from the outer periphery, the liquid drawn toward the shielding part or the liquid spreading against the shielding part collides with each other, and the gas flow path is provided to face each other so that The gas-liquid mixture in the opposite direction collides, so the particle size can be reduced. The locking end wall of the liquid supply path is arranged at an inner side of the closed wall before the upper injection port is provided; a small-diameter cylindrical portion is protruded from the locking end wall to make it interfere with the injection port The inner surface of the locking wall at the front end of the peripheral edge; an opposing groove is provided on the peripheral wall of the small-diameter cylindrical portion; the air flow passage is provided to pass through the groove while the liquid outflow hole is directed toward the inner surface of the groove; The liquid flowing out of the liquid hole collides with the shielding part and crosses with the gas passing through the groove; and, the paper standard facing China near the nozzle is applied to the Chinese National Standard (CNS) Α4 specification (210X297 mm) (Please read the precautions on the back before filling in this page) -Installation.

(Item 4 of the patent application park) Along the gas flow path that connects the gas supply path at the outer peripheral position and the shielding portion of the emission port, two or more opposed gas flow paths are formed; and, The angle formed by the opposite gas flow path is set to 18 (Γ ~ 30 ·. (Patent Application Fifth Item)) If the angle formed by the opposite gas flow path is 180 degrees, the opposite gas ram will touch The position of the thump is the internal position of the injection port; if it is 6 (Γ ~ 30 °, the position where the opposing gas collides is the external position of the injection port. In either case, the gas is along the inner surface of the injection port peripheral wall The flow path allows the gas to collide with the nipple, so the clam and liquid collide and mix inside the nozzle near the nozzle. Also, if the angle is set to less than 30 degrees, the gas mixed and collided will flow in the same direction In the laminar flow state, the particles are integrated into one and cause coarsening. Also, if it is greater than 180 degrees, the gas is not easy to be ejected forward from the injection port. As mentioned above * Because the gas supplied from the outer peripheral position is at the injection port Nearby internal or external collisions, Moreover, the gas flowing out of these jets has crossed the liquid plaque and collided with it, so it can collide with the particle size.

Description of invention (8 A7 B7 Employee's Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs printed out the liquid outflow holes 19f, 19g to the grooves 19j, 19k, and hit the front end of the nozzle body 18 to close the barium wall 18b to achieve grain withdrawal On the one hand, the high-pressure air supplied to the air-branch supply path 16 located at the outer periphery of the liquid pulp supply path 14 is passed through a gas supply path 21 (flow (The cross-sectional area is small), then the scintillator flows through the gas supply channel 22, hits the blocking wall 18b at the front end of the nozzle body 18, and then folds at a right angle, and rolls toward the gas supply channel 23, so that it passes through the nozzle tip 19 The grooves 19j, 19k flow out to the ejection port 20. When passing through the grooves 19j, 19k, the high-pressure air flows with the liquid that rolls out of the liquid outflow holes 19f, 19g and the liquid that bounces back against the front locking wall 18b, positive Collisions at the intersection cause the liquid to degranulate. The gas-liquid mixture thus degranulated is then located at the center of the inner side of the ejection port 20. It can be said that a frontal collision from both sides results in further degranulation to reduce the particle size The trail is even smaller. The grain mist is shot from the injection port 20. In the case of a nozzle, if the air side is in trouble and air cannot be supplied, or if there is a small amount of air, after the liquid hits a shielding portion formed by the lock wall 18b in front of the nozzle body 18 and the granules are removed, the The ejection port 20 is ejected, so it does not become a stick flow. In addition, when the liquid is a viscous liquid, the viscous liquid can collide with the shielding part to withdraw the granules. Furthermore, the liquid and air roll through The straight supply path is not curved, so it is not easy to block the curved part, or the accumulation of foreign objects, without maintenance, can make the liquid and gas pass through. Figures 5 and 6 show the second embodiment, which The difference between the first embodiment and the first embodiment is that the grooves 19j, 19k, 19p, and 19q are provided at the small-diameter cylindrical portion 19d of the nozzle tip 19 at intervals of 90 degrees, and the paper size of the groove bottom is applicable to the Chinese country. Standard (CNS) Α4 specification (210X297mm) (please read the precautions on the back before filling in this page). Installed? Τ 11 A7 B7 printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 5. Invention description (9) Set fluid separately Hip outflow holes 19f, 19g, 19r, and 19s. According to the second embodiment described above, the liquid and the gas-liquid that have been collided and flowed out from the four directions to the ejection port 20 are collided with erbium inside the center of the ejection port After mixing and further granulating the liquid, the liquid is ejected from the shot port 20. Figure 7 shows the third embodiment, which differs from the first embodiment in that the diameter at the tip 19 'of the mouth is set While one of the cylindrical portions 19'd is inclined to the bottom surfaces of the grooves 19Ί and 19'k, the inner surface of the front end blocking wall 18'b of the mouthpiece body 18 'facing the grooves 19'j and 19'k is inclined to form, and The bottom surfaces of the grooves are parallel. Then, a gas flow path 23 'formed between the bottom surface of the groove and the front end blocking wall 18'b is inclined so that the angle Θ of the opposite gas flow path 23' becomes 120 degrees. When the angle formed by the opposing gas flow path 23 'is set to 120 degrees, the gas-liquid mixture containing the micronized liqueur flowing out of the opposing gas flow path 23 collides and mixes right inside the injection port 20 . According to the fourth embodiment shown in FIG. 8, the angle formed by the opposing gas flow path 23 "is made 60 degrees. At this time, the gas-liquid containing the granulated liquid rolled out from the opposing gas flow path 23" The mixture is collided and mixed outside the injection port 20. In this way, the position of the gas containing the liquid that has collided with the liquid to form a particle withdrawal in advance and collided with each other can be the inner side of the nozzle that is more internal than the injection port 20, or can be just inside the injection port, than the injection The port is more external to any position on the outer side of the jet port; that is, as long as it is near the jet port. This paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) (please read the precautions on the back before filling in this page). Binding-12-s〇33 A7 B7 V. Description of the invention (10) Ministry of Economic Affairs Printed by the Consumer Cooperative of the Central Bureau of Standards. However, before collision and mixing in the vicinity of the injection port, the liquid must hit the closed end wall in front of the periphery of the injection port in advance, and the flowing gas M will cross the collision liquid and make the liquid The snorkel collides and mixes. In addition, according to the fifth embodiment shown in the ninth garden, an injection port 40 is provided at the center of the closed barium end wall 30a of the nozzle 30 connected to the inner cylinder formed with the liquid supply channel, and the injection port The peripheral wall 30b of 40 is provided with a pair of opposed through-holes 30c; the stalk rolling path 36 between the nozzle tip 30 and the nozzle body 35 communicates with the through-hole 30c. A large-diameter opening 35b is formed on the front end wall 35a of the nozzle body 35; the peripheral edge of the front end surface of the latching end wall 30a of the tip 30 of the nozzle is in contact with the inner periphery of the large-diameter opening 35b; The peripheral wall 30d of the shot port 40 protrudes outside. The liquid outflow hole 30e is opened on the inner surface of the through hole 30c; the through hole 30c is at a position facing the tucker outflow hole 30e, and the injection port 40 is in communication; and in this state, the neem is ejected from the liquid outflow hole 30e The body crosses and collides with the gas passing through the perforated hole 30c; and the gas-liquid mixture ejected from the opposite position collides frontally with each other at the internal position of the ejection port 40. According to the fifth embodiment described above, although the liquid ejected from the liquid eel roll-out hole 30e does not come into contact with the shielding portion formed by the wall surface, the liquid is ejected from the opposite side of the ejection port while being mixed with the gas mixture The gas-liquid mixture collides and mixes with each other, whereby the de-granulation of the liquid tattoo can be achieved reliably. Therefore, the reduction of the gas-water ratio can also prevent the coarsening of the particle size. The 10th series shows the sixth embodiment, which differs from the fifth embodiment in that the position of the liquid outflow hole 30e is set to face the inside of the through hole 30c, and the opposite inner surface 30g of the M through hole 30c As a shield. --------- Invitation-- (Please read the precautions on the back before filling out this page) This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) 13-V. Description of invention ( 11) A7 B7 Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy Therefore, the liquid ejected from the liquid outflow hole 3 (^ to the through hole 30 collides with the inner surface 30g of the through hole which becomes the shielding part, making the liquid into a granule The state is reflected and diffused. The gas passing through the through-hole 30c collides with the liquid atomized by this shielding part and cross-collision mixes, so that the granulation is further efficiently performed. Also, the gas is caused by the gas side. There is no supply of gas, or the supply of gas is reduced, and the liquid also hits the shielding part and diffuses while being evacuated, so it can prevent the liquid from being injured and being sprayed due to the emergence of a stick flow. It is the same as the fifth embodiment, so it will not be repeated here. [Effects of the invention] As can be seen from the above description, if the two-fluid nozzle according to the first paragraph of the patent application according to the present invention is applied to the inner side of the injection port, the gas Cross contact with liquid Mix, and make the gas-liquid mixture collide near the injection port (the inner side of the nozzle inside the fcb injection port, the external supply of the nozzle, or the inside of the injection port), so that M can indeed be formed into a liquid snake Removal of granules. Therefore, Di makes the gas-water ratio smaller and lowers the energy, and the particle size will not be coarsened, and the particles can still be sprayed. As a result, the energy can be reduced to achieve cost reduction. According to item 2 of the patent application, fluid spray uses the closed barium wall at the front end of the ejection port as the shielding part. Before ejecting the liquid from the ejection port, it first hits the shielding part. Even if the erbium gas is in trouble and only the liquid is ejected, the liquid will not be turned into a stick roll and ejected from the injection port, which can prevent the liquid pressure generated when the stick is rolled from being injured and being shot by the plaque. Furthermore, due to the flow The gas M and the liquid paper that is squeezed out towards the shielding part are in accordance with the Chinese National Standard (CNS) Α4 specification (210Χ297mm) (please read the precautions on the back before filling out this page)-Packing-Order 14 V. Description of the invention (l2) Α7 Β7 The Ministry of Economy, Central Standards Bureau, Employee Consumer Cooperative printed a cross to make it collide with the shielding part and the granules were mixed with the gas, and the gas-liquid mixture facing the injection port collided, so a further implementation could be achieved Granulation. Also, as described above, since the liquid hits the shielding portion M to achieve the granulation, the granulation can be achieved even if the viscosity "I" of heavy oil or the like is used as the liquid skeleton. And since the liquid flow path is not Curved straight, so there will be no sticking and accumulation of viscous body in the curved part. It can be applied to liquid spray of high viscosity.
