BACTERICIDAL IRRADIATOR Russian patent published in 2016 - IPC A61L9/20 A61L2/10 

FIELD: treatment plant.

SUBSTANCE: invention relates to disinfection of air and contaminated surfaces in absence of people. Bactericidal irradiator contains arranged in a box housing a power supply and control unit and gas-discharge low pressure mercury lamps, mounted in cartridges on top surface of housing, which are set as a guard in a grid around lamps and central rack with clamps, fixing lamp. Power supply and control unit comprises a network switching unit, a control unit and a power unit. Network switching unit is made in form of a push-button switch with fixed and normally open contacts, push-button switch for emergency shutdown without fixation with normally closed contacts, low voltage source and push-button switch without fixation with normally open contacts. Control unit comprises a multi-position mode switch and connected to low voltage source microprocessor. Power unit is provided with electronic control gear (ECG), equipped with controllers, number of which corresponds to number of mercury lamps, electronic ballasts control inputs connected to outputs of microprocessor, and outputs of controllers connected to inputs of microprocessor. Outputs of microprocessor are also connected to adders of elapsed time counter for gas-discharge lamps and counter for number of switches, light indication unit and audio warning unit.

EFFECT: invention increases convenience, reliability and safety of disinfection process.
