针对雾化器效果不明显等问题,采用对气流加热从而影响金属雾化的方法来提高雾化效果。结果表明,通过加热雾化气流可以有效减小晶粒的尺寸,表明加热气流是一种有效提高雾化效果的方法。对气瓶至雾化器的气流管道设置了加热装置,并对加热效果进行了模拟。结果表明,随着气流的流动,气体温度、速度均提高,在管道末端的气体速度、温度之间近似符合关系式:V=0.32T+155.4。
For the atomizer effect is not obvious and other issues, the use of air heating and thus affect the metal atomization method to improve the atomization effect. The results show that the size of the grains can be effectively reduced by heating the atomizing air stream, indicating that heating the air stream is a way to effectively improve the atomization effect. The heating device is set on the airflow pipe from the gas cylinder to the atomizer, and the heating effect is simulated. The results show that with the flow of gas, the gas temperature and velocity are all increased. The gas velocity and temperature at the end of the pipe approximately accord with the relation: V = 0.32T + 155.4.
