A solid cone pressure atomizing nozzle

Abstract

The invention relates to a solid conical pressure atomization nozzle which solves the problem that liquid mist sprayed by an existing solid conical pressure atomization nozzle is not uniform. The solid conical pressure atomization nozzle comprises an inner nozzle, an outer nozzle, a shell and an inner nozzle core. The outer nozzle comprises a rotational flow chamber with a tangential rotational flow hole. The inner nozzle comprises a conical inner nozzle spray hole which is led into the outer nozzle rotational flow chamber and provided with a downward small opening. An axial through hole is formed in the inner nozzle core. The inner nozzle core comprises an inner nozzle core base which is sleeved with the inner nozzle spray hole, wherein the outer surface of the inner nozzle core body is in a conical shape with a downward small end, and an annular channel is formed between the inner nozzle core base and the inner nozzle spray hole. During work, part of fluid enters the outer nozzle, the other part of the fluid enters the inner nozzle and is divided into two ways, the two ways of fluid pass through an inner nozzle core straight channel and the annular channel between the inner nozzle core and the inner nozzle correspondingly, are then impacted and mixed in the rotational flow chamber and conduct sufficient energy exchange with rotational flow entering the nozzle from the outer nozzle, and therefore more uniform liquid mist can be sprayed out.

Description

technical field [0001] The invention relates to the field of nozzles, in particular to a solid cone pressure atomization nozzle. Background technique [0002] In order to make the liquid fuel burn effectively in the combustion chamber, it is necessary to form a liquid mist with fine particles and uniform size through atomization, so as to increase the contact area between the liquid fuel and the combustion-supporting air and increase the evaporation and combustion speed of the liquid fuel. [0003] Nozzle design directly affects the atomization quality of liquid fuel. At present, the commonly used nozzle type is bubble atomization nozzle, which mixes a small amount of gas in the fluid to achieve a solid cone atomization effect. The supply system is relatively complicated, the use environment is limited, and the spray particles are not uniform enough.
