Filtering type jet flow aerosol sampling device

The invention relates to the technical field of aerosol monitoring, and discloses a filtering type jet aerosol sampling device which comprises a supporting bracket, a front baffle, a gas guide hole, a gas stop valve, a three-stage filter paper holder, a high-pressure flow meter, a vent hole and an interlayer gasket. According to the invention, the aerosol is carried by shock waves to reach the sampler and is deposited on the filtering device, a gas path is cut off and opened through the pressure-sensitive gas stop valve, and the sampling volume is measured by using the high-pressure flowmeter; the device has strong tolerance to high temperature and high pressure, and all the components are sequentially connected and placed on a sampler support to complete jet sampling work. The device is simple and convenient to operate and high in reliability, can be used for carrying out jet sampling on various aerosol particles in a high-temperature and high-pressure chemical explosion scene and dynamic loading or other ai
