Abstract

The invention discloses a gas-liquid coaxial ejection liquid fuel electrostatic atomization nozzle. A needle-like corona charging electrode coaxial with a fuel corona charging chamber is placed in the fuel corona charging chamber, the right end of the fuel corona charging chamber is connected with an atomization swirler and a nozzle body which are coaxial with the fuel corona charging chamber, and the right end of the nozzle body is connected with a coaxial gas swirler. A left conical hole and a right conical hole which are coaxial and are communicated are formed right in the middle of the nozzle body. A conical atomization swirler is sleeved with the left conical hole of the nozzle body. The nozzle body is provided with a plurality of gas impact holes communicated with a gas inlet pipeline and the right conical hole of the nozzle body. The gas swirler is provided with a plurality of gas whirl flat holes communicated with the gas inlet pipeline and the outside. Corona discharge is carried out on the liquid fuel, the electrified liquid fuel is atomized through the static electricity and centrifugal force, the impact type auxiliary atomization is carried out on the liquid fuel through gas flow, the atomized drops interact with the air coaxially ejected after leaving the nozzle, and the combustion efficiency is improved.

Description

technical field [0001] The invention relates to the electrostatic atomization technology of liquid fuel, in particular to an electrostatic atomization nozzle of non-conductive liquid fuel, which can be atomized to form stable gas-liquid spray. Background technique [0002] Electrostatic atomization of liquid fuel is a liquid fuel atomization technology and method that relies on electrostatic force. The fuel droplets produced by atomization have many advantages such as small particle size, monodisperse uniform distribution, stable state, and narrow droplet size distribution range. , can significantly increase the gas-liquid contact area, improve the combustion efficiency of liquid fuel, and reduce the emission of CO, NO and fine particles. [0003] The Chinese patent application number is 200920047470.8, and the name is "a gas-liquid coaxial inflow electrostatic atomization nozzle for pesticide spraying". The nozzle structure disclosed mainly solves the problem of efficient a...

Problems solved by technology

However, due to the complexity of the structure of the dual-fuel nozzle, the manufacture is more complicated and the cost is higher, and the insulating ceramic tube inside the nozzle is not conducive to the formation of ion clusters

[0005] At present, there are many devices that use electrostatic technology to realize the effective atomization of conductive media such as water, but there is no report on the device that uses electrostatic atomization to realize the atomization of non-conductive liquid fuels.
