Embodiment 1

[0025] Such as figure 1 shown, combined with figure 2 , 3 As shown, the atomizing nozzle in the present invention includes a nozzle body 1, and the nozzle body 1 is provided with an air flow channel 2 and a liquid channel 3, and the air flow channel 2 and the liquid channel 3 are arranged at an angle, from the air flow channel 2 The ejected air flow can intersect the liquid ejected from the liquid channel 3. The number of the air flow channel 2 is one, which is arranged in the middle of the nozzle body 1 , and there are multiple liquid channels 3 , and the plurality of liquid channels 3 are evenly distributed around the air flow channel 2 . A liquid storage ring 4 is also provided on the nozzle body 1 , and the liquid storage ring 4 communicates with the liquid channel 3 .

[0026] The nozzle body 1 includes an integrally formed first body part 101 and a second body part 102, the first body part 101 is in the shape of a truncated cone, the second body part 102 is in the sh...

Embodiment 2

[0034] The difference between the present embodiment and the first embodiment is that the number of the liquid channel 3 is one. Such as Figure 7 As shown, the liquid channel 3 is arranged beside the air flow channel 2 .

Embodiment 3

[0036] The difference between this embodiment and the first embodiment is that the number of liquid channels 3 is two. Such as Figure 8 As shown, the two liquid channels 3 are symmetrically arranged on both sides of the gas flow channel 2 .

Abstract

The invention discloses an atomizing nozzle and an atomizing spray head using the atomizing nozzle, relates to the atomizing nozzle for atomizing a liquid medium and the atomizing spray head using the atomizing nozzle, and aims to provide the atomizing nozzle capable of efficiently atomizing the medium at high speed and the atomizing spray head using the atomizing nozzle. The atomizing nozzle comprises a nozzle body (1); the nozzle body (1) is provided with an airflow channel (2) and a liquid channel (3); and the airflow channel and the liquid channel form an included angle. The atomizing spray head using the atomizing nozzle further comprises a spray head connecting piece (5) and a shell (6); the atomizing nozzle is connected to the shell through the spray head connecting piece; an airflow through hole (9) and a liquid through hole (10) are formed in the spray head connecting piece; one end of the airflow through hole is communicated with the airflow channel, and the other end is connected with an air supply pipe fitting (7); and one end of the liquid through hole is communicated with the liquid channel, and the other end is connected with a liquid supply pipe fitting (8).

Description

technical field [0001] The invention relates to an atomizing device, in particular to an atomizing nozzle for atomizing a liquid medium and an atomizing nozzle using the atomizing nozzle. Background technique [0002] Atomizing nozzle is a common fluid mechanical equipment, widely used in liquid rocket engine ignition system, rocket engine test bench cooling system, launching water spray cooling and noise reduction system, petrochemical catalytic equipment, agricultural and forestry irrigation system, industrial dust purification system, firepower Power plant desulfurization and dust removal equipment and air pollution control and purification system. [0003] The atomization efficiency of atomizing nozzles has always been a concern of rocket engine ignition systems, petrochemical catalytic equipment, desulfurization and dust removal equipment, etc. At present, atomizing nozzles are often developed based on improving the structure of the atomizing nozzle itself, such as ato...
