Cyclone for nozzle

Abstract

The invention relates to the technical field of cyclones and discloses a cyclone for a nozzle. The cyclone comprises a cyclone body, six swirling flow channels, a nozzle and a spray tube. The cyclonebody is located in an inner cavity of the spray tube, the six swirling flow channels are uniformly arranged on the outer wall of the cyclone body, the nozzle is located on the right side face of the spray tube, the periphery of the outer wall of the cyclone body is in contact with the inner wall of the spray tube, the six swirling flow channels are obliquely arranged on the outer wall of the cyclone body, the left side of the nozzle is connected to the right side face of the spray tube, and spray holes penetrating from left to right are uniformly formed in the right side of the nozzle. By replacing a conventional metal cyclone with a ceramic cyclone to replace application of a high-temperature alloy to a conventional nozzle, rare metal resources are saved. As for the swirling flow channelsformed in the outer wall of the cyclone body, advanced chemical etching and grinding forming techniques are adopted. Compared with conventional manual operation grinding, the processing grade is higher and more excellent, and the processing precision is better and more controllable.

Description

technical field [0001] The invention relates to the technical field of cyclones, in particular to a cyclone for nozzles. Background technique [0002] The swirler for the nozzle is a part that the fluid is thrown to the inner wall of the nozzle due to the inertial centrifugal force through its swirling action under the pressure drive, and is gradually sprayed outward (flowing) while rotating. Compared with conventional parts, its structure is more complex and not easy to process, and it consumes a lot of kinetic energy during the working process, and it wears seriously under high pressure, so it is generally made of wear-resistant alloy and requires a certain smoothness index. At present, industrial high-temperature nozzles High-temperature alloy materials are mostly used in hydrocyclones, and traditional processing and forming technologies are used. Considering its harsh working environment, high-temperature alloys have become the best choice for processing materials. Afte...

Problems solved by technology

[0003] The roughness of the swirl channel is low, and visual oil passages often appear during the performance debugging process, that is, the circumferential uniformity of the atomization degree is poor, and it takes a lot of manual work to grind the swirl channel more finely, but manual work The grinding effect is unmeasurable and uncontrollable due to human factors and other factors, resulting in poor consistency of grinding quality and obvious individual differences. The hardness of metal materials is lower than that of ceramic materials. Under long-term service, it is easy to change the size or even the structure of the flow channel. This situation is more obvious under high-pressure conditions, which will affect the injection flow rate of the nozzle and the instability of the mist cone angle, and affect the stability of the combustion process. Moreover, the swirler needs to be suitable Equipped with a special nozzle mechanism, the complex structure of the special nozzle for the cyclone on the market also affects the normal use of the cyclone
