【摘要】：电陶瓷加湿器喷杆安装位置和喷嘴朝向对加湿效果的影响问题进行了探讨。以数值模拟为基础通过计算流体力学软件Fluent对送回风管路及喷杆近壁处静压分布进行研究,理论分析加湿的可能性,并就分析结果的准确性加以试验验证。结果表明:(1)喷杆置于回风管中,喷嘴顺流布置和喷嘴逆流布置均可实现加湿目的。喷嘴顺流布置时,随着温度的升高相对湿度由68.7%升高到82%。喷嘴逆流布置时,随着温度的升高相对湿度由61.7%升高到74.6%;(2)喷杆置于送风管路,当加湿器内没有附加压力时,由于近壁处的高压作用在传统加湿器包括电陶瓷加湿器内产生的处于微小正压状态下的蒸汽将无法喷入送风气流,几乎达不到加湿目的。
[Abstract]:The influence of installation position of injection rod and nozzle orientation on humidification effect of electric ceramic humidifier is discussed. Based on the numerical simulation, the static pressure distribution of the return air pipeline and the jet rod near the wall was studied by the computational fluid dynamics software Fluent, the possibility of humidification was analyzed theoretically, and the accuracy of the analysis results was tested and verified. The results show that the nozzle downstream arrangement and the nozzle countercurrent arrangement can achieve the purpose of humidification. The relative humidity increased from 68.7% to 822 when the nozzle was arranged downstream. When the nozzle countercurrent is arranged, the relative humidity increases from 61.7% to 74.6% with the increase of temperature) the injection rod is placed in the air supply line, when there is no additional pressure in the humidifier, Because of the high pressure near the wall in the traditional humidifier, including the electric ceramic humidifier, the steam produced under the small positive pressure will not be injected into the air flow, which can hardly achieve the purpose of humidification.
