Description

The utility model relates to ventilation systems for closed poultry houses.

The closest analogue is the PAD LING humidification and cooling system / AGROVENT catalog, pages 44-45. WWW.t Agrovent.ru/.

The disadvantage of the closest analogue is the complexity of the system and the high cost of materials.

The technical result is expressed in increasing the efficiency of the ventilation system and reducing material costs.

The essence of the device for humidifying and cooling wall-mounted ventilation cassettes of poultry houses is characterized by a set of common features with the closest analogue, containing a pipe with holes for water supply from above, a cassette of material evaporating water and a water collector. The device differs from the closest analogue in the following features: from the top of the ventilation cassettes there are horizontal polymer or fiberglass pressure pipes with special nozzles for spraying water, installed two pieces above each ventilation cassette, each of which is made of two layers of geomat with rubber water collectors at the bottom, while ventilation the cassettes are fixed to the supply window grilles. To supply water with pressure to a polymer or fiberglass pipe, a pressure tank made of polymer material is provided, installed on the ceiling or attached above the level of the pipes. A water supply is connected to the tank for filling with water to a certain level, pieces of ice are added to the tank periodically, up to 30% of the total volume of the tank, while regulating valves are installed on the pressure pipe in front of the tank and at the bottom of the tank on the pressure pipe to control the water pressure and humidity of the ventilation cassettes on the water supply.

The essence of the device for humidifying and cooling ventilation cassettes of closed poultry houses is illustrated by drawings, where figure 1 shows a diagram of humidification and cooling of ventilation cassettes in a poultry house in perspective, figure 2 is a section of the cartridge along the line of the supply window with a humidifying nozzle from above, figure 3 is a section of a pressure pipe with water spray nozzles and geomat cassette with rubber sump at the bottom.

A device for humidifying and cooling ventilation cassettes in closed poultry houses consists of a pressure tank (1) with cold water and pieces of ice (2), a pressure pipe (3) with water spray nozzles (4), ventilation cassettes (5). The tank (1) is supplied with a water supply with a control valve (6). Ventilation cassettes (5) consist of two layers of geomat, glued together, and with rubber water collectors (7) attached from below. Ventilation cassettes (5) are mounted on metal grilles of supply windows (8). On the pressure pipe (3) at the bottom of the tank (1) there is a control valve (9).

The design and calculation of the elements of the device for humidifying and cooling the ventilation cassettes of closed poultry houses is carried out in accordance with the current building codes and regulations, taking into account the technological conditions and features of the poultry houses. The device is designed for tunnel, transverse and combined ventilation systems in poultry houses.

All elements of the device are prepared in advance and brought to the installation site of the ventilation system for poultry houses. First, a pressure tank (1) and a pipe (3) with water spray nozzles (4) are manufactured. The pressure tank (1) is installed on the roof of the house or attached to the top of the wall and is supplied with water. A valve is installed to the pipe in front of the tank (1). A pipe with two nozzles (3) is pulled from the pressure tank (1) over the window openings. It is necessary that the nozzles are located strictly above the ventilation windows. To regulate the pressure and flow of water and the humidity of the cassettes (5), a valve (8) is installed on the pipe (3) at the bottom of the tank. And the ventilation cassettes (5) are made of geomat glued together in two layers, 4-6 cm thick.

A rubber sump (7) is attached to the bottom of the cassette (5) so that water drops flowing from the cassettes freely fall into the sump container (7). In this case, an outlet valve must be provided in the water collector (7) for periodic drainage of water from it. Ventilation cassettes (5) are attached to window metal grilles (8) with the possibility of their removal and replacement, if necessary.

A device for humidifying and cooling the ventilation cassettes of poultry houses provides effective cooling and humidification of the supply of warm and dry air during high summer temperatures (from about mid-July to mid-August). To do this, at the beginning, the pressure tank (1) is filled with cold water and the previously brought pieces of ice (2) are added to it. Ice can be purchased from nearby refrigeration units or food processing plants. The volume and pressure of water in the tank (1), the number of added pieces of ice (2) and the frequency of their addition are selected for each house separately, depending on specific conditions. The cooled water from the tank (1) enters the pipe system (3) and under pressure through the nozzles (4) water particles are sprayed over the cassettes (5), then (under the action of gravitational forces) they evenly flow down the outer layer and seep into the geomats of the cassettes ( 5), where the cassettes are humidified and cooled (5). At the same time, fans installed inside the housing of the poultry house provide exhaust and air circulation inside the air basin with air flow through the ventilation humidifying and cooling cassettes (5). This ensures that cooling air is supplied and circulated within the poultry house. Dry and warm air, passing through the cassettes (5), partially removes moisture from the cassettes and turns into cold and humid. The remaining water flows down the cassette and then falls into the rubber sump (7). To increase the efficiency of the ventilation cassettes (5), the time of periodic descent of water from the water collectors (7) is selected.

Geomats are good at letting air through and are saturated with water, part of the water evaporates from the surface, evaporation occurs due to the energy of hot air, which passing through the cassettes is not only humidified, but also cooled. To achieve the required flow and maximum effect, the area of cassettes 5 and the power of the exhaust (tunnel, etc.) fans must be correctly calculated. According to preliminary calculations, the use of chilled water from the head tank (1) allows to reduce energy consumption for the operation of fans by 25-30%.

The device for humidification and cooling of ventilation cassettes can be most effectively used with a tunnel ventilation system for poultry houses, but it can also be used with a transverse and combined ventilation system. At the same time, in comparison with the analogue, the material costs for its devices and operation are significantly reduced due to the use of cheap materials and a decrease in energy consumption.
