The invention discloses a filtering and collecting device for engine exhaust emission particulate matters. An outer shell is cylindrical, and a plurality of vent holes are arranged on a bottom plate of the outer shell, the other side of the outer shell is open, a groove is arranged on an inner wall of the outer shell on the inner side of the bottom plate, and a particle discharge port is arrangedon the side wall of the outer shell; a filter screen is cap-shaped, is provided with a sealing ring and a conical column; and the sealing ring of the filter screen is embedded in the groove of the outer shell. The outer shell is made of polytetrafluoroethylene, polypropylene or polyethylene. The filter screen is made of nylon or polytetrafluoroethylene through sintering. The filter screen can filter out 100% of particulate matters discharged by an automobile. The pollution of the particulate matters to the air environment is avoided, and the body health of people is protected. The filter screen can be repeatedly cleaned and used due to the material of the filter screen, and the use cost is reduced. The filtering and collecting device for the engine exhaust emission particulate matters provided by the invention can also be mounted in an automobile air conditioning system and used for filtering and isolating dust and viruses in air, namely, the filtering and collecting device is used asa cab air filtering and dust virus isolating device.
发动机尾气排放颗粒物的过滤和收集装置,其外壳体呈筒状,外壳体的底板开设有若干通气孔,外壳体的另一侧为敞口,底板内侧的外壳体内壁开设有凹槽,外壳体的侧壁开设有颗粒排出口;过滤网呈帽子形,过滤网具有密封圈,过滤网具有锥形柱;过滤网的密封圈镶嵌在外壳体的凹槽中。外壳体的材质为聚四氟乙烯、聚丙烯或聚乙烯。过滤筛网的材质为尼龙或聚四氟乙烯烧结而成。过滤筛网能过100%滤掉汽车排放的颗粒物。杜绝了颗粒物对空气环境的污染,保护了人的身体健康。过滤网的材质使过滤网能反复清洗使用,降低了使用成本。本发明还能安装在汽车空调系统中,用于过滤和隔离空气中的灰尘和病毒,即用作驾乘室空气过滤灰尘病毒隔离装置使用。
