Problems solved by technology

[0003] At present, the common type of smoke detector widely used in these places is limited by factors such as low detection sensitivity, which is insufficient for the very early detection of fire. It basically belongs to the confirmation detection of fire, and it is difficult to predict and predict fire The function of fire prevention cannot meet the requirements for super early detection and alarm of fire

Abstract

The invention discloses a particle counting aerosol detecting device, which comprises the following parts: laser, laser beam spatial correcting lens, laser beam spatial filtering pipe, detecting room, laser beam rack, aerosol detecting lens component, aerosol detector tray component, aerosol scattering detector, aerosol detector accident detecting luminotron, light hole and deflector plate. The device realizes the darkest background design of aerosol particle counting detection, minimal scattering action region and detecting field of vision design of single particle scattering impulse counting detection, which affirms the structure need of single aerosol highest sensibility particle impulse scattering signal.

Description

Technical field [0001] The invention belongs to the technical field of fire detection and alarm, and can also be applied to the field of clean technology, and particularly relates to a particle meter type smoke detection device. Background technique [0002] With the development of my country's economic construction, some special places that play a vital role in the national economy and social life, such as computing centers, graphic archives information centers, post and telecommunications hubs, integrated circuit production workshops, nuclear power plants, large-scale modern dispatching Control centers, intelligent building control centers, modern medical institutions, etc., have increasingly urgent requirements for fire safety. Due to the high concentration of various internal electrical equipment and long-term operation, there are many hidden dangers of fire. Once a fire occurs, it will cause great economic losses to the country and have a significant impact on the society. I...
