Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-8, the natural gas nozzle suitable for the wind tunnel environment comprises a kiln wind tunnel 1, wherein a plurality of air supply pipes 2 are radially and uniformly distributed at the bottom of the kiln wind tunnel 1, and one ends of the air supply pipes 2 penetrate through the kiln wind tunnel 1 and extend to the inside and are connected with nozzles 3. Four transverse spray holes 31 are formed in the inner end of the spray head 3, five longitudinal spray holes 32 are formed in the top of the inner end of the spray head 3, and a windward platform 33 for shielding wind for the transverse spray holes 31 is fixedly connected to the bottom of the inner end of the spray head 3. As shown in fig. 1, the nozzle 3 is installed inside the wind tunnel 1 and connected to the air supply pipe 2, so that natural gas can be supplied through the air supply pipe 2, the transverse nozzle hole 31 and the longitudinal nozzle hole 32 are respectively formed at the end and the top, and the situation that strong wind mixed with materials blows the nozzle from bottom to top can be avoided, and the situations of flapping, pipe blockage and tempering are avoided.
The diameters of the transverse spray holes 31 and the longitudinal spray holes 32 are both 18mm. The four transverse spray holes 31 are uniformly opened around the inner diameter at 90 degrees, and the five longitudinal spray holes 32 are uniformly opened around the outer diameter at 35 degrees. As shown in fig. 2, through many experiments and improvements on the diameter and position layout of the transverse nozzle holes 31 and the longitudinal nozzle holes 32, it is found that when four transverse nozzle holes 31 are circularly arranged at 90 °, five longitudinal nozzle holes 32 are arcuately arranged at 35 °, and the diameter is 18mm, the fire is strong and the nozzle is not easily affected by strong wind.
The thickness of the windward table 33 is 15mm. As shown in fig. 2 and 4, the windward platform 33 is a half circular ring, the windward platform 33 protrudes out of a part of the nozzle 3, and the bottom of the windward platform is chamfered, so that the transverse nozzle hole 31 is not affected, and strong wind can be blocked, so that the strong wind blows flame upwards, the strong wind is prevented from directly contacting with the transverse nozzle hole 31, and blockage and backfire are also avoided.
The internal diameter of shower nozzle 3 is 130mm, the external diameter of shower nozzle 3 is 160mm, the internal diameter centre of a circle is higher than external diameter centre of a circle 5mm. As shown in fig. 6, 7 and 8, the inner diameter of the nozzle 3 does not correspond to the circle center of the outer diameter, and the circle center of the inner diameter is higher than the circle center of the outer diameter, so that the thickness of the bottom of the nozzle 3 is thicker than that of the top of the nozzle, and the thicker bottom can avoid being rapidly eroded and immersed because the bottom is facing to the strong wind mixed with the material, thereby prolonging the service life of the nozzle.
