Abstract
The utility model provides a cyclonic nozzle, and comprises an outer shell of a nozzle body. A cyclone with a spiral groove is arranged inside the outer shell of the nozzle body. A flange is arranged at the inlet of the nozzle body. The nozzle body is connected with the flange via a connecting sleeve. The outer shell behind the tail end of the cyclone is a convergent section, the inner surface of which is a smoothly-transiting arc surface. The tail end of the outer shell is a nozzle with two holes. With the calculating method of the modern hydrodynamics in combination with the nozzle design experience, the spiral groove is designed for the utility model so as to promote the atomization efficiency of the gas-liquid mixture and overcome the shortcoming of the low atomization efficiency of a traditional pressure nozzle. Meanwhile, the pneumatic resistance of the nozzle is reduced, and the operating energy consumption is reduced obviously. In order to promote the abrasion resistance of the cyclone on some application occasions, abrasion-resistant materials are used for the cyclone or the surface of the cyclone is hardened, to form a abrasion-resistant layer and prolong the service life.
Description
One, technical field
The utility model relates to a kind of nozzle.Specifically a kind of nozzle that is applied to the atomizing of gas-liquid mixture.
Two, background technology
Original nozzle is to the atomizing of gas-liquid mixture, applying pressure formula nozzle generally speaking, and being gas-liquid mixture, service condition must possess certain pressure, shortcoming be have that nozzle is easy to wear, service life problem such as weak point, atomizing effect difference, and general air flow type jet nozzle requires gas to separate with liquid, gas and liquid is not blending before atomizing, and therefore general air flow type jet nozzle can not the atomization gas liquid mixture, can only applying pressure formula nozzle to the occasion of atomization gas liquid mixture.
Three, summary of the invention
The purpose of this utility model is to provide a kind of can be applied to atomization gas liquid mixture occasion, and atomizing effect is good, the air flow type jet nozzle of long service life.
The purpose of this utility model is achieved in that it comprises the nozzle body shell, in the nozzle body shell, be provided with the cyclone of band helical groove, nozzle body import department is provided with flange, nozzle body is connected with flange by adapter sleeve, the body housing of the terminal back of cyclone is a converging portion, the inner surface of converging portion is the arcwall face that seamlessly transits, and the body housing end is a shower nozzle, and shower nozzle has two holes.
The utility model can also comprise some architectural features like this:
1, interference fit between cyclone and the body housing.
2, the cone angle of described converging portion is between 10-15 °.
3, the direction in the hole on the described shower nozzle becomes 10-15 ° of angle with airflow direction.
4, the helical groove on the cyclone is a rectangle, and the width of groove is between 6-8mm.
5, on the groove surfaces of cyclone wearing layer is arranged.
6, between adapter sleeve and the flange limit screw is arranged.
The utility model utilizes the modern fluid mechanics computational methods in conjunction with the designs of nozzles experience, design the helical groove shape, thereby improved the nebulization efficiency of gas-liquid mixture, overcome the low shortcoming of traditional pressure type nebulization efficiency, make the aerodynamic drag of nozzle reduce simultaneously, operation energy consumption obviously descends.In order to improve the wearability of cyclone under some application scenario, cyclone adopts high-abrasive material or cure process is carried out on the surface, forms wearing layer, increases the service life.
The utility model can be applicable to the atomizing of gas-liquid mixture, as the alkali lye separation of knockout tower in the petrochemical field, compresses the atomizing of water in (gas) machine water filling cooling etc.
