The invention provides an electrostatic inactivation device for removing microbial aerosol in air and an inactivation method of the electrostatic inactivation device. A device main body is of a hollow structure with two open ends, a charge area and an inactivation collection area are integrated and arranged in the device main body, the charge area consists of an electrostatic discharge system, the electrostatic discharge system comprises a discharge electrode and a supporting frame, and the discharge electrode is relatively fixed to the supporting frame, is connected with a high-voltage direct-current power supply, and ionizes surrounding aerosol through discharging; the inactivation collection area is relatively arranged on the side wall of the device main body, comprises an electrode plate and a collection vessel, and is used for collecting inactivated aerosol; and an air inlet assembly and an air outlet assembly are respectively arranged at the open openings of the device main body. The microbial aerosol is inactivated by using an electrostatic technology, and the microbial aerosol in the air is removed; ozone released in the charging process can strengthen the inactivation effect on aerosol; and the electrode plate and the discharge electrode can be dismounted, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of electrostatic sterilization, in particular to an electrostatic inactivation device and an inactivation method for removing microbial aerosols in the air. Background technique [0002] Aerosol is a multiphase system composed of the atmosphere and solid and liquid particles suspended in it. It is a mixed dispersion system. The two-phase dispersion system formed by biological particles suspended in the air and air is called bioaerosol. [0003] The aerodynamic equivalent diameter of bioaerosol is usually between 0.01-100 μm, suspended in the air, containing particles such as viruses, bacteria, rickettsia, chlamydia, mycoplasma, etc., is a mixed dispersion system, representative The particle size is 0.1-10μm, which exists in the air in a stable or quasi-stable system state, and enters the human body through life activities such as human breathing. The germs carried in the aerosol can cause diseases such as ca...
