MEANS OF SOLVING THE PROBLEM OF BIOLOGICAL PURIFICATION OF POLLUTED AIR IN CLOSED ROOMS USING THE ADDITIONAL COMPOSITE FILTER “AIR GUARD”

Abstract

A multi-layer filter design has been developed for purifying air in enclosed spaces where people stay for long periods of time. The use of basalt fabric, hemp-based “konoplepon” fabric, linen, and carbon fabric is proposed. Each layer of the filter has a special function to trap polluting particles of different sizes and chemical composition. Due to the chemical resistance of basalt, the first layer of the filter will be resistant to aggressive environments, and with its high fire resistance, it will protect against flames. Hemp composite has certain antiseptic properties and a porous structure to trap dirt particles. The use of carbon composite in the form of fabric is unique, as this type of fabric has high adsorbing properties and maximally purifies the air from biocidal pollutants. The cartridge system allows for timely replacement or cleaning of the filter. All materials used in filters are environmentally friendly and do not pollute the external environment. To increase the wear resistance of carbon fabric when used in ventilation systems, two types of coatings are proposed for application to its surface. One option is to apply chitosan, which is biological in nature and can be used when the fabric comes into contact with skin. The second option is the spraying of nanoand micro-layers of Teflon, which increases the strength and resistance of carbon fabric to external destructive influences. The design solution can be implemented in ventilation systems of various scales. It is possible to expand the scope of application for transport too.
