Embodiment Construction

[0028] The working principle of the sterilizer is as follows.

[0029] The turbine 4 forces air into the sterilization chamber 2, and the air flow passes through the sterilization chamber under the action of the electric field. The electric field is generated by the corona electrodes 7 and 9, and the power sources 13 and 14 act on them to generate an amplitude of 14-100 kV and a duration of 2 ~200ms, positive and negative high-voltage pulses with a density of 1~100, and the voltage value and pulse duration can be set independently. The pulse duration can be determined according to the following formula:

[0030] t=S / Va, where

[0031] t-pulse duration, ms

[0032] S-length of sterilization chamber, m

[0033] V- the speed of air passing through the sterilization chamber, m / s

[0034] а - Coefficient of magnetic interaction.

[0035] Sterile air escapes from the sterilization chamber 2. The electrodes 10 of the ionizer increase the concentration of aeronegative ions in the...

Abstract

A method for inactivating microorganisms in the air comprises feeding the air through a system of corona electrodes (7, 9) and ionizer electrodes (10) arranged in a sterilizing chamber (2) in a magnetic field; applying high-voltage impulses of positive and negative polarity with an amplitude of 14-100 kV for the duration of 2-200 msec and a density of 1-100, with the possibility of independently setting the voltage value. The electrical sterilizer comprises a housing (1) and the sterilizing chamber (2) where the positive (9) and negative (7) corona electrodes are arranged, which are connectedto high-voltage pulsed power supplies. Isolated electrodes (8) are positioned between the positive (9) and negative (7) corona electrodes, the former being configured in the form of a dielectric bodywith metal meshes imbedded therein. The ionizer electrodes (10) are mounted on the last negative electrode in the direction of the airflow. At least four electromagnets (11) are installed on the sterilizing chamber (2) with the power supplies thereof being positioned outside the housing (3) of the sterilizing chamber and synchronized with the power supplies of the electrodes. A turbine (4) and aninjector (5) for an additional gas supply are installed before the sterilizer inlet.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a method and an inactivation device for inactivating microorganisms in the air, which can be used for air disinfection and increasing the level of air negative ions in industries such as medical treatment, pharmacy, food, agriculture, and crowded areas in daily life. Background technique [0002] There is a range of air cleaning and disinfection devices of simple or complex design. However, all known devices cannot achieve complete purification of the air from a microbiological point of view. [0003] More famous is the air purifier of ZENET brand (Internet resource: http. / www.mobilluck.com.ua / brands / Zenct), it carries out air purification with mechanical and electrostatic means, but wherein does not have inactivation condition. [0004] A similar situation is the case with air purifiers of the brand AIRcomfort (Internet source: www.aircomfort.ru). Nano-type filter elements ar...
