The invention relates to a device for the preparation of the air supplied to the ventilated space for special purposes.

The known device for air treatment, which has the ultrafine filters for air purification (Clean room, Ed. by A.E. Fedotov, Moscow, asinkom, 1998, s). These filters are designed for air purification from suspended impurities, including from microflora with a particle size greater than 0.33 μm. On the constructive characteristics and achieved the effect these devices have been adopted as a prototype.

The disadvantage of the prototype is that caught mainactivity microflora forms on the filters ultrafine cleaning of the colony, and multiplies. Individuals microflora size less than 0.3 microns penetrate into the ventilated space special purpose and degrade the hygiene of air, which can lead to the violation of technological process (in the wine industry, the production of drugs), or to various diseases of people in the premises of special purpose medical institutions.

The technical result of the invention is to improve the efficiency of purification of air supplied to the ventilated space for special purposes from microorganisms, including bacteria.

The technical result is achieved in that the device is in for air preparation consists of louvered grill, which feature mullioned insulated valve, coarse filter air filter air, heat exchanger, blower, muffler, duct and filter over thin air purification. Set section on the back of the high frequency of inactivation of microorganisms, having a housing in the shape of a parallelogram with a length of 0.3-1 m, which are mounted in a parallel circuit design insulated cylindrical working chamber with a diameter of 0.1-0.6 m high-frequency generators at the entrance, each working chamber is mounted swirl for a spin flow of cleaned air, and the filter section of the carbon materials.

Built swirl will provide a swirling flow of cleaned air with particles microflora, increase the length of the flow path and increase the exposure time of the high-frequency radiation on particles microflora, as in swirling flows heat transfer processes occur in 30-40% more intense, will increase the efficiency of air cleaning from microflora by their inactivation and will repay the axial component of velocity at the outlet of the working chamber before the filter from carbon materials. The speed of cleaned air in the living section along the axis of each working chamber section of the high frequency of inactivation of the microflora should not exceed 3 feet per second when the section length is 0.3-1 meter, ensure Ecevit necessary time of exposure radiation on particles microflora for their inactivation. The frequency generator high frequency radiation should be within 2375-22125 MHz, because at this frequency provides an efficient inactivation particle microflora in the swirling flow of cleaned air. Section high frequency of inactivation of the microflora tightly secures the filter of carbon materials with holes for the passage of cleaned air is not more than 0.3 μm.

The installation section of the high frequency of inactivation of the microflora ensures inactivation of microorganisms, including bacteria. Spin air through the swirler provides rotational movement of the flow with particles microflora, which guarantees exposure to radio frequency radiation on the entire surface of the particles of the microflora and the intensity of heat and mass transfer by at least 30-40% and the damping of the axial velocity component at the outlet of the working chamber.

Install the filter section of the carbon materials provides the adsorption of inactivated particles of microorganisms, including bacteria, as they are protein compounds that effectively sorbed by the filter of the carbon materials.

The carbon filter material mounted in the housing section so that the distance from the working chamber section of the high frequency of inactivation of the microflora should be not less than three diameters of the working kamerik the filter section of the carbon material is attached to the duct, to the other end of which is attached a filter ultrafine cleaning.

The principle of operation of the device for air treatment is that outside air enters the louvered grill 1 passes which feature mullioned insulated valve 2, is purified by a coarse filter air 3, and filter air 4, and flows into the heat exchanger 5 for heating or cooling.

Using the swirl clear the air with particles microflora twists and moves along a cylindrical working chamber in the section of the high frequency of inactivation of the microflora 8 along a helical path that provides the necessary exposure time radiation on particles microflora and increases the effectiveness of their inactivation by increasing the intensity of heat transfer in swirling the om thread at least 30-40% and reduces the axial component of velocity at the outlet of the working chamber.
