Description

The invention relates to agriculture, in particular to methods for creating the optimal microclimate on farms, and can also be used for dehydration of air in the premises of bath and laundry plants.

A known method of sanitary treatment of air in livestock buildings, including the supply of external air, mixing the external and internal air, obtaining condensate and collecting it in a tray located under the heat exchanger, heating the air and draining [1].

The reasons that impede the achievement of the technical result indicated below when using this method include increased energy consumption for heating the incoming outdoor air and the removal of a significant amount of heat with the exhaust air.

There is also known a method of sanitary treatment of air in a livestock building, including the supply of external and internal air through a triangular shaped duct, the formation of condensate on it and its collection into the sewers through a V-shaped visor fixed under the duct [2], adopted as a prototype.

The reasons that impede the achievement of the technical result indicated below when using the known method adopted for the prototype include the fact that in the known method, moisture condensation on a triangular cross-section duct occurs due to the presence in the room air of a certain number of moisture condensation centers, i.e. dust particles, smoke particles, etc., floating in the atmosphere, and entirely depends on their amount in the indoor air of the room, which is not enough for timely and guaranteed dehydration of air to sanitary standards, as well as removal of harmful impurities together with condensate.

The essence of the invention is to use the ability of a radioactive gas of radon, everywhere and constantly emanating from the bowels of the earth, to ionize air to artificially produce ions near the duct, i.e. an additional number of new droplet nuclei nuclei due to the capture of radon under the floor of the truss placed in the trap and its subsequent transportation from the trap to the triangular duct through pipes.

In particular, the collection of radon radioactive gas under the floor of the livestock building into a specially designed trap for this purpose and the subsequent transportation of radon through pipes from the trap to a triangular duct cooled by cold external air below the dew point of the indoor air of the room, leads, under the influence of radioactive gas of radon, to ionization of air molecules and the formation of ions of different signs near the duct of a triangular shape, in connection with this in the space between the duct and the V-shaped goat In addition to the existing centers of moisture condensation, new droplet nuclei appear on the ions, i.e. additional moisture condensation centers, which activates the process of dehydration and purification of the indoor air from harmful impurities that come into contact with the condensate.

The technical result is the acceleration of the process of moisture condensation from the internal air of the room and the removal of harmful impurities from it.

The specified technical result in the implementation of the invention is achieved by the fact that in the known method of sanitizing air in a livestock building, comprising supplying external and internal air through a triangular cross-sectional duct, maintaining the outer surface of the duct below the dew point of the indoor air, condensation and collection thereon into the sewer through a V-shaped visor, mounted under the duct, a triangular cross-section duct is blown with radon gas Coming to it from the ground through pipes connected to trap radioactive radon gas situated under the floor of the livestock facilities.

The acceleration of the process of moisture condensation and the purification of internal air in a triangular cross-section duct occurs due to the appearance of ions near it, formed due to ionization of the air under the influence of radioactive gas of radon, coming to it from the bowels of the earth through pipes from a trap built under the floor of the livestock building, which attract steam molecules to themselves and form tiny droplets that serve as centers of further moisture condensation.

The proposed method is illustrated by drawings.

Figure 1, 2 shows a diagram of a livestock building with a triangular-shaped duct located in it and a V-shaped visor for collecting condensate suspended under it, a trap for radon radioactive gas and pipes transporting radon from the trap to the duct.

Information confirming the possibility of carrying out the invention with obtaining the above technical result.

The method is as follows. A mixture of warm moist recirculated and external cold air under the pressure of the suction fan passes inside a triangular duct 1 installed under the ceiling of the livestock building 2, and constantly maintains a temperature below the dew point of the internal air on the outer surface of the duct 1.

The dehydration of internal air is carried out by obtaining condensate 3 from the farm air on the outer surface of the suction triangular duct 1, and collecting and transporting it into the sewers through a metal V-shaped visor 4, suspended under the duct 1 on the brackets 5.

Condensate 3 is obtained on the nuclei of droplet nuclei, which, along with dust particles, smoke particles, etc., are ions of different signs formed near the triangular duct 1 due to air ionization by radon emanations coming to it from a trap 6 formed, for example, from airtight concrete foundation 7 and floor 8 of room 2, through polyethylene, for example, pipes 9, or by gravity 10, and, if necessary, using a fan 11.

The ingress of radon radioactive gas into the region of duct 1 cooled by external cold air, below the dew point of the indoor indoor air, causes ionization of air molecules near the duct and contributes to the intensive formation of condensate 3 on it due to the additional number of droplet nucleus centers in the form of ions of different signs.

The supply of a sufficient number of droplet nuclei in the form of ions of different signs into the space between the V-shaped visor 4 and the duct 1 of the triangular shape, obtained in the process of ionizing the air with radioactive gas, radon, which is a natural active agent, accelerates the process of water condensation on the walls of the triangular duct 1 the internal air of the livestock building and contributes to its cleaning from harmful impurities that are removed with condensate.

Thus, the above information indicates that when using the claimed invention (method), the following combination of conditions:

- the tool in its implementation is intended for use in agriculture, namely when creating the optimal microclimate on farms, in particular, cleaning the internal air of livestock buildings from moisture and harmful impurities;

- for the claimed method in the form described in the independent clause of the claims, the possibility of its implementation using the means and methods described in the application or known prior to the priority date is confirmed.

Therefore, the claimed invention meets the condition of "industrial applicability".
