Multifunctional long-lasting protection ventilating device

Abstract

The invention discloses a multifunctional long-lasting protection ventilating device which comprises a shell (16). The middle part of the shell (16) is divided into an upper part and a lower part through a middle partition plate (11). The upper portion of the right side of the shell (16) is provided with an upper cover plate (2) through an upper border flange (19), and the lower portion of the right side of the shell (16) is provided with a lower cover plate (1) through a lower border flange (20). Two air inlets (25) are formed in the upper portion of the upper cover plate (2), and a dust discharging outlet (26) is formed in the bottom of the upper cover plate (2). A support partition plate (18) is arranged inside the shell (16) and further located in front of the upper cover plate (2). Dust exhausting fans (4) are installed between the upper portion of the support partition plate (18) and the corresponding air inlets (25) of the upper cover plate (2). A pre-filtering module (3) is installed below the support partition plate (18). The multifunctional long-lasting protection ventilating device is a widely-popularized and high-efficiency protection device and can be used both at ordinary times and at emergency periods; and the practicability is high and the application range is wide.

Description

technical field [0001] The invention belongs to the field of purifiers, in particular to a multifunctional long-acting protective ventilation device, which has two functions of common purification and poison filtering. Background technique [0002] In recent years, as the demand for nuclear, biological and chemical protection continues to expand, protective vehicles have developed rapidly, and protective systems have also been systematically and integratedly developed. As the core components of the system, the existing ventilation devices generally only have the function of protective ventilation. There is no cleaning and ventilation function, so protective ventilation can only be carried out in extraordinary periods, and it can only protect against toxic and harmful aerosols and chemical agents. The ability to protect against industrial toxic and harmful gases is very limited. Harmful gases have a certain adsorption capacity, even if used under the condition of no pollutant...

[0002] In recent years, as the demand for nuclear, biological and chemical protection continues to expand, protective vehicles have developed rapidly, and protective systems have also been systematically and integratedly developed. As the core components of the system, the existing ventilation devices generally only have the function of protective ventilation. There is no cleaning and ventilation function, so protective ventilation can only be carried out in extraordinary periods, and it can only protect against toxic and harmful aerosols and chemical agents. The ability to protect against industrial toxic and harmful gases is very limited. Harmful gases have a certain adsorption capacity, even if used under the condition of no pollutants, the protective function will be reduced or even lost, so it cannot be used in normal times, and the utilization rate of the equipment is very low
