A carrier is used to carry a liquid, and a high voltage is applied between a discharge end of the carrier and an opposed electrode to emit ionized liquid particles. The carrier has a liquid collecting end opposite to the discharge end to feed the steam of the liquid from a steam generator, condensing the liquid therearound, and feeding the condensed liquid to the discharge end. Accordingly, even when the liquid contains cations such as those of Ca and Mg, the steam of the liquid can extremely reduce the content of these impurities, avoiding the precipitation of the impurities at the discharge end of the carrier to assure stable electrostatic atomization.

The invention relates to the field of catalytic cracking productive chemicals, in particular to an efficient atomizing nozzle technology for crude oil. Provided is a bubble breaking and target type impact combined reinforced throat pipe type nozzle. According to the nozzle, first-stage bubble breaking, second-stage impact breaking, third-stage throat pipe type breaking and fourth-stage throat pipetype re-breaking are included. Finally, crude oil enters a spray head (24) through an expansion buffer chamber (18) and is sprayed out from a nozzle spout (19). Due to the fact that the nozzle spoutis inclined, thin fan-shaped spraying mist flow is finally formed, and the mist flow can be fully mixed with catalyst particle flow from the pre-lifting section. According to the novel nozzle, the principle of instant bubble blasting is fully utilized, the advantages and characteristics of a target type nozzle and a throat pipe type nozzle are integrated, the atomization performance of high-viscosity crude oil is greatly improved, fog drops with small particle sizes and narrow particle size distribution are effectively generated, and the nozzle has the characteristics of adjustable droplet ejection speed, low gas-liquid ratio, stable atomization process, high operation elasticity, simple structure, impact wear resistance, reduction of coking in the cracking process and the like.

Water is fed from a tank to a capillary carrier having an emitter end from which an ionized water particle is emitted by a voltage being applied across the emitter end and an opposed electrode. A cation exchanger is provided to remove minerals such as Ca2+ and Mg2+ from the water being fed through the capillary carrier or from the water to be fed to the carrier from the tank, thereby avoiding the ions from precipitating at the emitter end as CaCO3 or MgO in reaction with CO2 in the surrounding air, and therefore assure reliable electrostatic atomization over a long period of time.

The invention relates to a multilevel free-type gas atomization spraying tray with the gas self-circulation function. The multilevel free-type gas atomization spraying tray comprises an auxiliary nozzle, a main nozzle and a recycling gas flow guide part. The auxiliary nozzle is connected with the upper end of the recycling gas flow guide part, and the lower end of the recycling gas flow guide partis connected with the main nozzle. A melt channel of the auxiliary nozzle, a melt channel of the recycling gas flow guide part and a melt channel of the main nozzle communicate with one another up and down. A recycling flow guide channel is formed between the recycling gas flow guide part and the main nozzle. The recycling flow guide channel communicates with the melt channel of the main nozzle,and when the main nozzle is installed on a partition plate between a smelting chamber and an atomizing chamber, the recycling flow guide channel can communicate with the atomizing chamber. Compared with the prior art, auxiliary nozzle airflow is used for draining molten steel and further lowering negative pressure of a main nozzle atomization area, main nozzle jacket holes and the recycling gas flow guide part are used for achieving atomizing gas self-circulation, and therefore gas balancing of the main nozzle atomization area is realized, and stable and smooth execution of the atomizing process is guaranteed.
