摘要
高效滤芯是空气净化器的关键部件,当空气净化器中流向高效滤芯部分的送风不均匀时,会导致滤芯利用率较低,从而影响滤芯的过滤性能.为提高滤芯的使用效率进而改善装置的净化性能,可以在风机和高效滤芯之间放置导流型等离子体发生器,利用发生器的导流板使送风气流更均匀的吹向滤芯.为探究适宜的导流板结构参数,采用数值模拟的方法对不同结构参数导流板下的流动过程进行分析,通过对比滤芯使用率和送风均匀性等指标,给出适宜的导流板长度和张开角度设计方案.研究结果表明,对于本文研究的净化器尺寸,导流板设计长度为100 mm、张开角度为10°时的送风更均匀.优化后的尾部导流板结构简单、设计合理、使用方便,分散了送风气流的方向,更有利于提高后端高效滤芯的利用率和使用寿命.
The efficient filter is a critical component of an air purifier,when the airflow directed towards the efficient filter is uneven,it results in lower utilization of the filter,thereby affecting its filtering performance.To enhance the efficiency of the filter and consequently improve the purification performance of the device,a flow-guiding plasma generator can be placed between the fan and the efficient filter.This generator utilizes guiding plates to direct the airflow more evenly towards the filter.To investigate the suitable structural parameters of these guiding plates,numerical simulations were employed to analyze the flow processes under various structural parameters.By comparing indicators such as filter utilization and airflow uniformity,suitable design schemes for the length and opening angle of the guiding plates were proposed.The research findings indicated that,for the dimensions of the purifier studied in this paper,a guiding plate with a length of 100 mm and an opening angle of 10°resulted in more uniform airflow.The optimized design of the rear guiding plate was simple,well-designed,and convenient to use.It dispersed the direction of the airflow,thereby significantly enhancing the utilization and lifespan of the rear efficient filter.
