Comparative Test of Atomization Characteristics of Three Desulfurization Nozzles
In order to understand the atomization characteristics of different types of desulfurization nozzles,spiral nozzles,solid cone nozzles and hollow cone nozzles are selected as the research objects,and clean water is used as the test working fluid,and the variation of performance parameters such as range,flow rate,atomization angle and droplet size of these three desulfurization nozzles under different water supply pressures is studied by combining laser particle size analyzer.The test results show that firstly the droplet size of the nozzle is negatively correlated with the water supply pressure,and the flow,range,atomization angle are positively correlated with the water supply pressure.Secondly,the flow rate of the spiral nozzle changes the most,and its flow coefficient is 0.495,and the flow rate of the solid cone nozzle does not change significantly when the water supply pressure gradually increases.Thirdly,with the initial water supply pressure of 0.2 MPa,the atomization angle of the spiral nozzle is much larger than that of the solid cone nozzle and the hollow cone nozzle,reaching 148.6°.At the same water supply pressure,the range of the spiral nozzle is smaller than that of the other two nozzles,and lastly,the droplet size of the three nozzles is large under the initial water supply pressure of 0.2 MPa,and the atomization effect is not good.With the increase of water supply pressure,the maximum value of droplet volume frequency shows a law of decreasing particle size.Based on the results of atomization characteristics,the atomization performance of the spiral nozzle is better,and it is more suitable for the actual production process.
