VENTILATION SYSTEM WITH AIR CLEANING AND DISINFECTION Russian patent published in 2022 - IPC A61L9/15 B01D46/00 B01D50/00 

FIELD: ventilation and air conditioning.

SUBSTANCE: invention is intended to ensure effective intake of foul air, cleaning and disinfection, relates to ventilation systems with air cleaning by pre-treatment, chemical oxidation and sorption and has a wide range of use, in particular, can be used for arrangement of ventilation system of plunder branch of sewage pumping station located in the boundaries of populated point, building of grates of treatment facilities, snow melting points, control tanks, etc. Method includes forced or natural supply of fresh air above the ceiling or, in the presence of a room, in the upper part of the room and air intake by the exhaust ventilation system from under the floor of the room, covering channel or reservoir, where there is directly source of foul and toxic gases, by organizing directed air flow through openings in floor or overlapping downwards. Further, the removed foul air is cleaned using the system. Cleaning system consists of one or more preliminary filters, air duct from ozone-resistant material, reactor, a sorption filter, an exhaust fan with a noise silencer at the outlet of at least one ozone generator with an air preparation system, a control controller, an ozone concentration sensor at the inlet of a sorption filter, an ozone concentration sensor, a hydrogen sulphide concentration sensor and an air flow velocity sensor at the output of the system, as well as an ozone concentration sensor above the floor or in the room and an independent gas analyzer with ozone sensors located in the most probable places of people.

EFFECT: complete exclusion or minimization of foul and toxic gases over a partially overlapped channel or reservoir with source of foul and toxic gases and in removed air exhaust ventilation system, intensification, high quality and reliability of the air cleaning process, safe operation of the ventilation system with air cleaning and longer life of the structure and structure.
