Description

The invention relates to agriculture in terms of energy supply and irrigation of greenhouses in order to optimize energy consumption for heating and lighting of the greenhouse, as well as intra-soil thermoregulated irrigation of the root area of cultivated crops. The use of this invention will allow for savings and more efficient use of energy and water resources spent for the efficient operation of greenhouses.

A device for heating a greenhouse comprising a boiler, a heating system of a tent of a greenhouse connected to a boiler, a contact heat exchanger of the heat of combustion products, a ground heating system of a greenhouse, a heated water storage tank, an air decarbonizer with a gas outlet pipe connected to the atmosphere and a gas distribution system having a carbon dioxide generator (USSR copyright certificate No. 1111706, class A01G 9/24, 1982).

The disadvantages of the device are low productivity and increased fuel consumption, excessive consumption of electricity spent on the operation of the electric fan. In addition, this device does not allow the generation of additional electric energy, accumulate it and use it in the future to illuminate the greenhouse, as well as provide temperature-controlled intra-soil irrigation of crops grown.

The closest technical solution is a device containing a boiler, a heating system of the tent of the greenhouse connected to the boiler, a contact heat exchanger of the heat of combustion products, a system of underground heating of the greenhouse, a storage tank, an air decarbonizer with a vapor outlet pipe connected by a pipe to the suction duct of the boiler’s blower fan, the gas distribution system of the greenhouse (patent RU No. 2087094, IPC A01G 9/24, 1997).

This device does not allow to generate additional electric energy, accumulate it and use it in the future to illuminate the premises of the greenhouse and other household needs, as well as to provide temperature-controlled intra-soil irrigation of crops grown.

The technical result achieved by the present invention is to save and increase the efficiency of the use of energy resources for heating, lighting and water resources for temperature-controlled intra-soil irrigation of the root-inhabited area of cultivated crops. The consequence of this is the high performance of greenhouses.

This technical result is achieved by the fact that the energy supply and subsurface irrigation system of the greenhouse (hereinafter referred to as the "System") consists of a water boiler equipped with a thermogenerator module, inlet and outlet heating pipelines with ground plate radiators and a subsurface part, a water supply expansion tank connected to a flexible distribution hose with subsoil humidifiers, gas distribution devices and batteries.

Figure 1 - "System" (General view).

The proposed “System” consists of: a circulation heating circuit equipped with a water boiler (1) with a thermogenerator module (22), a supply pipe (2), a centrifugal pump (3), a discharge pipe (4), ground plate radiators (5), and a subsoil heating part (6), water supply pipe (7) with shut-off valve (8), water supply expansion tank (9) with shut-off valve (10) connected to a flexible distribution hose (11), equipped with a shut-off valve (12), individual connections (13 ) with constipation cranes (14) and subsoil humidifiers (15) perforated in the lower part (16), devices for removing products of fuel combustion into the atmosphere (17), a gas distribution device (18) equipped with a shut-off valve (19), a filter (20) and deflectors (21), electrical wires (23), and batteries (24).

"System" works as follows. The circulation heating circuit is started by switching on the water boiler (1) equipped with a thermogenerator module (22) and a centrifugal pump (3). Water heated to the required temperature circulates through ground plate radiators (5), the subsoil heating part (6) while creating a certain temperature in the greenhouse. Irrigation of plants grown in a greenhouse is carried out from a water supply expansion tank (9) connected to a flexible distribution hose (11). When water reaches the temperature required for the circulation heating circuit to irrigate the root area of plants, the shut-off valve (10) opens and water enters the flexible distribution hose (11), then through individual connections (13) it enters subsoil moisturizers (15) and, accordingly, in the root habitat of plants, uniformly moistening the soil layer throughout its volume. If necessary, one or more humidifiers is turned off from operation by closing shut-off valves (14). When emptying the water supply expansion tank (9), the shut-off valve (8) opens on the water supply pipeline (7) and is filled. Water is supplied to the circulation heating circuit by opening the shut-off valve (10). The products of combustion of fuel generated during the operation of the water boiler (1) are discharged into the atmosphere using the device (17). With a lack of carbon dioxide, which is formed during the combustion of fuel in a water boiler (1), which is necessary for the vegetation of plants, a gas distribution device (18) comes into operation. To turn on the gas distribution device (18), a shut-off valve (19) is opened and carbon dioxide, being cleaned from the remaining combustion products in the filter (20), enters through the deflectors (21) into the greenhouse, contributing to the active vegetation of cultivated crops. Excess thermal energy generated during the combustion of fuel in a water boiler (1) is converted into electrical energy using a thermogenerator module (22), which works on the basis of the temperature difference between its sides. Obtained, as a result of this, electric energy is supplied through electric wires (23) to storage batteries (24), from which it can be used to illuminate the premises of the greenhouse and other household needs.

The result of the system’s work scheme is to save and increase the efficiency of the use of energy resources for heating, lighting and water resources for subsurface irrigation of crops, as well as maintaining the required temperature and moisturizing the root layer, which improves the quality of the course of the vegetation period of plants and, accordingly, the effectiveness of the operation of greenhouses.
