According to the jet type atomization device and the atomization method, a specific
airflow channel is constructed, so that high-speed
airflow is jetted to central liquid flow from the periphery, and front and violent
momentum exchange type collision is formed at an outlet of a mixing cavity instead of simple shearing, so that superfine atomization is realized at a lower gas-
liquid ratio; the collision structure ensures that the whole cross section of the liquid flow can be violently impacted and broken by the air flow, so that the overall atomization uniformity is improved, and the generation of large-particle-size liquid drops is avoided; the head of the
nozzle is arranged in the special through hole or the sleeve on the wall surface of the pipeline, and the protective gas hood is utilized to form a heat insulation barrier, so that a key injection part of the
nozzle is not directly exposed in mainstream high-temperature
fuel gas, continuous
impact of hot
airflow and particles is avoided,
carbon deposition is remarkably reduced, and the service life of the
nozzle is prolonged. And meanwhile, due to the
modular design, the nozzle is convenient to maintain and use in different application scenes.
