ABSTRACT OF THE DISCLOSURE Apparatus for neutralizing and purifying air, compris- ing successively: an air filter, able to remove from the air to be treated, the particles of predetermined sizes; a preliminary drier comprising a cooling tunnel through which passes the filter- ed air and which first comprises a coil pertaining to the circuit of a frigorific machine and then a plurality of deflectors remov- ing partially the liquid particles and droplets existing or formed in the air to be treated owing to its cooling to their dew point; two driers operating alternatingly and showing each a cooling tunnel through which passes the predried air, which first com- prises a coil pertaining to the circuit of another frigorific machine and then a plurality of deflectors completely removing the liquid droplets and particles remaining in the predried air or formed during its subsequent cooling until temperatures of -20 to -40°C, and which is provided with a defrosting system; a turbine moving the air flow to be treated through its circuit; an intensive cooling unit receiving the dried air and comprising essentially first a heat exchanger cooperating with a powerful frigorific machine to intensely cool the dried air, then a separa- tor for separating the droplets and particles of liquefied gas, formed during the cooling of the dried air, then a separator for separating the solid particles existing or formed during the same cooling of said dry air, the microorganisms and the virusses, and finally another heat exchanger to reheat the dry and treated air to about the inlet temperature of the first exchanger.
