Description

The invention relates to agriculture, in particular to the purification of air emissions of livestock complexes with obtaining green biomass, as well as for fertilizing the soil.

A well-known livestock farm (ed. St. USSR 1554842, A01K 1/00), in which the transparent tube chambers are divided by a glass partition into two sections, one of which is located in the room for growing animals, and the other in the germination, while the gas exchange apparatus is installed in the room for growing animals behind a glass partition, and gas and gas pipes are located respectively in the lower part of the room for growing animals and the growth.

The germination and premises for raising animals are interconnected with the atmosphere through air holes with dampers, and the germination is oriented to the south.

The gas exchange apparatus is made in the form of a cooling tower with a chlorella sump having a drainage device, while the casing of the cooling tower on the outside is equipped with heat exchange fins.

The disadvantage of this device is the design complexity due to the presence of a gas exchange apparatus and glass tubular chambers, as well as low reliability due to the large presence of glass parts.

Closest to the technical nature of the claimed device relates to a device for cleaning air emissions and wastewater of livestock complexes using plants (RF patent No. 2179158, C02F 3/32, C05F 7/00), containing containers for growing plants, an air pump, a piping system for removal of polluted air and wastewater, lighting elements. Capacities for growing plants are arranged in tiers on the walls of the casing and have bottoms inclined towards the walls of the casing with reflective outer surfaces, and the lighting elements are made in the form of lamps that are located in the center of the casing between the rows of tiers of containers.

The disadvantage of this device is that the walls of the casing are made of reflective material, so it is necessary to use time-consuming additional operations, which ultimately complicates the manufacturing technology. In this device, when growing plants, an increased content of relative humidity occurs, as a result of which the walls of the body will fog up, which reduces the reliability and efficiency of the structure.

The disadvantage of this device is the presence in the drains of a large number of microbiological contaminants, fungi, bacteria, helminth eggs, etc. All these bacteriological and microbiological organisms can be transmitted through animal feed, which negatively affects the health of the animal.

The disadvantage is that the water supplied to the tank for growing plants is not heated, and therefore negatively affects the growth and development of plants.

The objective of the invention is to simplify the design and increase the reliability of the device by supplying contaminated air directly to the root system and using carbon dioxide to feed plants.

The problem is solved due to the fact that the device for cleaning air emissions of livestock complexes using plants, containing containers for growing plants, an air pump, a system of pipelines for discharging contaminated air, characterized in that the pipelines for discharging contaminated air are installed under the ridge of the livestock complex, the air pump outlet is connected through a heater to a temperature controller with aeration drainage pipelines installed at a depth of 10 to 25 cm from the surface of the soil.

New significant features:

1. Pipelines for the removal of polluted air are installed under the ridge of the livestock complex;

2. The output of the air pump is connected through a heater to a temperature controller with aeration drainage pipelines;

3. The aeration drainage pipe is installed at a depth of 10 to 25 cm from the soil surface.

The listed new essential features, together with the known ones, are necessary and sufficient to achieve a technical result in all cases to which the requested amount of legal protection applies.

Warm polluted air rises to the top of the livestock building due to the pressure difference, where perforated air ducts are located under the ridge, which suck warm polluted air through a perforation with an air pump, and through a heater with a temperature regulator are fed into the aeration drainage system, which has perforation throughout the buried part pipelines located in the greenhouse.

The aeration drainage pipe is laid to a depth of 10 to 25 cm from the soil surface, depending on the crop being grown. When polluted air enters moist soil, the impurities of carbon dioxide, ammonia, and hydrogen sulfide partially dissolve in soil moisture, which is a top dressing for growing plants. In the case when the temperature is lower than that required for optimal plant growth, a heater is connected and the temperature of the air supplied to the soil is regulated, creating the optimum temperature for the plants.

Ammonia and hydrogen sulfide are more soluble than carbon dioxide, and therefore completely soluble in soil moisture. Plants absorb carbon dioxide not only from the soil using the root system, but also from the air. Since carbon dioxide, passing through the soil as a filter, enters the air, which will also be fertilizing plants. By absorbing these elements, plants will release oxygen. Biological treatment of air emissions of livestock buildings and the saving of mineral fertilizers, and protection as a result of the environment from air emissions of livestock buildings.

The drawing shows a functional diagram of a device for cleaning the air of a livestock building in plan.

A device for cleaning the air of a livestock building 1 with walls 2 contains a suction air pump 3 connected to a perforated air duct 4, a heater 5 with a temperature regulator 6 (for example, an electric air heater), and aeration drainage pipelines 7 having a perforation located in the greenhouse along the entire buried length 8.

A device for air purification of a livestock building works as follows.

In the livestock building 1, warm air due to the pressure difference is concentrated in the upper part of the room where the perforated duct 4 is located. Using an air pump 3, warm, polluted air from the livestock building 1 enters the perforated duct 4 located under the ridge of the roof of the livestock building 1, and injected into the greenhouse 8, where the plants are located. At the same time, air from the livestock building 1 is fed into the greenhouse 8 using aeration drainage pipelines 7. The soil with pipelines 7 laid in it is essentially a water scrubber with organic filler. The aeration drainage pipe 7 is laid to a depth of 10 to 25 cm from the soil surface, depending on the crop being grown. The air supplied through pipelines 7, aerating through the soil, is in contact with soil moisture. In the case when the temperature is lower than that required for optimal plant growth, a heater 6 is connected and the temperature of the air supplied to the soil is regulated, creating the optimum temperature for the plants. Possessing high solubility, impurities of carbon dioxide, ammonia and hydrogen sulfide contained in air dissolve in soil moisture and enter into chemical compounds with soil components.

The air purified by the subsoil system again enters the room 1, thereby eliminating the problem of recirculation of polluted air inside the room, and the air of the room 1 is saturated with oxygen, which has a beneficial effect on farm animals and thereby eliminates the effect of emission of harmful emissions into the atmosphere.
