本发明涉及一种手提式湿壁气旋微生物气溶胶采集器,主要包括进风隔离罩,进风部件,通风管道,补液组件,风机部件,采样杯,过滤部件,连接板等,所述进风部件的侧面上均匀开有锐切的进风口,空气进风隔离罩进入进风部件中,通过进风部件上的锐切口中在进风部件和采样杯中形成气旋涡,空气中气溶胶作旋转运动,颗粒和水雾受到惯性离心力作用而向采样杯内壁移动与采样液结合,本发明采样过程可有效防止虫子进入采集器,采样简单,适用于不用粒径的气溶胶高效采集,应用在不同的场合,整个系统组装简单,小巧轻便,系统整体具有采样高效性和便携性。
The present invention relates to a portable wet-wall cyclonic microbial aerosol collector, mainly comprising an inlet air isolation hood, inlet air components, ventilation ducts, replenishment components, fan components, sampling cups, filtering components, connection plates, etc. Sharp-edged inlet ports are uniformly opened on the side of the inlet air components. Air enters the inlet air isolation hood and then flows into the inlet air components. A cyclonic vortex is formed in the inlet air components and the sampling cup through the sharp-edged ports on the inlet air components. Aerosols in the air rotate within the vortex, and particles and water mist move towards the inner wall of the sampling cup due to the action of inertial centrifugal force, combining with the sampling liquid. This invention effectively prevents insects from entering the collector during the sampling process. The sampling process is simple and suitable for efficient collection of aerosols with different particle sizes. It can be applied in various scenarios, and the entire system is easy to assemble, compact, and lightweight, with high sampling efficiency and portability.
