    摘要: The invention relates to automated devices for pro¬ducing aerosols of liquid disinfectants and for spraying same. A mo¬bile hygiene unit comprises a housing (1) containing a disinfectant spraying unit (2) with a spraying nozzle (3), a tank (4) containing disinfectant, a compressor (5), and a control unit (6). It further com¬prises a mechanism for regulating the droplet size distribution of the aerosol, including a pump (7), an electromagnetic valve (8), and a dosing nozzle (9) with an internal cylinder. The disinfectant spraying unit (2) comprises a shaped nozzle (3) having a nozzle head (10) of axisymmetric cross-section attached thereto, and a mixing chamber (11) for mixing disinfectant with compressed air, having two thread¬ed inlets for a pneumatic line (12) and a hydraulic line (13), said inlets being arranged at an angle of 180°. The dosing nozzle (9) contains an internal cylinder and a rod with a threaded tip. The mobile hygiene unit generates an aerosol in four droplet size distribution modes: dry fog (from 3.5 to 10 pm), wet fog (from 10 to 30 pm), mist (from 30 to 50 pm), and spray (from 50 to 100 pm). The invention allows highly precise regulation of the droplet size distribution of the aerosol in each mode without the need to change the spraying nozzle.

    摘要: The invention relates to the chemical industry and can be used in the production of an aqueous chlorine dioxide solution for disinfection, water purification, sterilization and bleaching. To produce a stabilized aqueous chlorine dioxide solution, in the first step two aqueous solutions, (A) and (B), are prepared. To prepare the first solution (A), metallic or ammonium chloride (A1), metallic or ammonium carbonate (A2) and metallic or ammonium bicarbonate (A3) are dissolved in water. The mass ratio of (B1) to (A2+A3) is (2.4-3.0):1. To prepare the second solution (B), metallic or ammonium persulfate (B1) and metallic or ammonium bisulfate (B2) are dissolved in water. The mass ratio of (B1) to (B2) is 3:1. In the second step, solution (B) is added to solution (A). The invention provides maximum production of the end product (aqueous chlorine dioxide solution) that does not have destabilizing side products and can be stored at a temperature of up to 30° C. and at normal atmospheric pressure for at least 12 months.
