Abstract

The invention relates to an aerosol monitoring alarm apparatus and a detection method thereof. The invention discloses the aerosol monitoring alarm apparatus which is characterized by comprising an optical tank, a photoelectric conversion system and a circuit system, wherein the photoelectric conversion system comprises a photomultiplier and a connection base; the optical tank is an air-tight dark chamber and is internally provided with a light source lamp, a gas particle cutter, a standard scatter plate, a correction measurement knob and an air pump; the light source lamp and the gas particle cutter are arranged on the two sides of the optical tank and are located on the same height; the correction measurement knob is arranged on the outer wall of the optical tank and is connected with the standard scatter plate by a rotary structure; the photoelectric conversion system is arranged on the outer wall of the optical tank; a light window of the photomultiplier is vertical to the light path of the light source lamp by a slit in the outer wall of the optical tank; the circuit system comprises a power supply circuit system, a photoelectric conversion and range conversion circuit system and a single chip microcomputer control circuit system.

Description

technical field [0001] The invention relates to an aerosol monitoring and alarming instrument and a detection method thereof. Background technique [0002] Aerosol is a suspension system of liquid or solid particles in the air. Atmospheric aerosol refers to a multiphase system composed of solid and liquid particles suspended in the atmosphere with a particle size between 0.01 and 100 microns, mainly including six categories and seven types of particles: dust aerosol, carbon aerosol ( black carbon and organic carbon aerosols), salt aerosols, etc. [0003] Aerosols pose a certain threat to human health. Aerosol particles with a particle size greater than 5 microns are easily blocked by the respiratory tract, and some are excreted from the body by coughing and spitting, but they can stimulate local mucous membranes and cause chronic rhinitis and pharyngitis. . The aerosol particles smaller than 5 microns can directly enter the lungs to cause disease, especially 50% of the pa...
