Abstract

The invention relates to an air-conditioning technique and improves the efficiency of air humidification. A hollow rotor 1 with openings 2, with spraying disks 3 and profiled plates 4 is immersed with a lower base 5 in a vessel 6 with water, and an upper base 7 is attached to the shaft 8 of the actuator 9, an air nozzle 11 is installed inside the rotor, fixed with the lower end in the bottom of the vessel 6, and its upper end is set above the water level in the vessel 6. Plate 12 breaks are installed in the upper base 7 of the rotor 1 at an acute angle α to the plane of the disks 3. As the rotor 1 rotates, water from the vessel 6 rises through the gap 13 on the inner surface rotor 1 and its post Leniye hole 2. Simultaneously, under the action of the rotating plates 4, plates 12 and 11 through the pipe air flow occurs inside the device. At the same time, the air stream in the hole 2 is located in its center, and at the same time a film of water is distributed along the wall of the hole 2.

The invention relates to the technique of air conditioning and can be used to humidify air in agricultural premises.

The aim of the invention is to increase the efficiency of air humidification,

1 shows a device for humidifying air; figure 2 is a view of And figure 1; on fig.Z - section bb in figure 2.

The air humidification device contains a hollow rotor 1 with holes 2, with spray discs 3 and profile plates 4, immersed with a lower base 5 in a vessel 6 with water, and with an upper base 7 attached to the shaft 8 of the actuator 9, and air outlet guides 10 placed concentrically relative to the profile plates 4.

The device is equipped with a vertical air nozzle 11 and radial plates 12, the nozzle is installed inside the hollow rotor 1 with a gap 13, fixed with the lower end in the bottom of the vessel 6 and communicated with the atmosphere, and the upper end is installed above the water level in the vessel 6, the radial plates 12 are installed in the upper base 7 of the rotor 1 at an acute angle to the plane of the discs 3, with the apex of the angle X pointing in the direction opposite to the direction of rotation of the rotor 1. At the entrance to the nozzle 11 a filter (not shown) for air attached to the bottom of the vessel 6.

The device also contains the main channels 14 for the entry of humidified air into the internal cavity of the device and the elements 15 of mutual attachment of the upper and lower parts of the device

The device works as follows.

When the shaft 8 of the actuator 9 or the rotor 1, the disks 3 with the profile plates 4 rotates, the water from the vessel 6 rises through the gap 13 due to centrifugal forces along the inner surface of the rotor 1 and enters the aperture 2. Simultaneously under the influence of the rotating plates 4, acting as an impeller, fan, there is a supply of humidified air from the space surrounding the device

inside the device. At the same time, under the influence of the plates 4 located between the disks 3, a relatively small amount of air is taken (calculated, for example, 1 kg of air per 1 kg of sprayed water) s since the air path is throttled by the holes 2. This volume of air (30 60 kg / hr) is fed through the pipe 1I from the bottom of the device and is pumped from above to the plates 12, the arrangement of which at an acute angle provides the role of an additional axial fan. B hole 2 simultaneously receives water under the action of centrifugal forces and air under the action of the profile plates 4 located between the disks 3. At the same time, the air stream in the hole 2 is located in its center, while simultaneously distributing a film of water along the wall of the hole 2, thus reducing the thickness of this film .

At the outflow of water and air from the opening 2, a dispersed water is dispersed due to the throttle effect (pressure drop) resulting from the sudden expansion that occurs at the outlet of the openings.

2. Spray droplets under the action of inertia and ejection forces, arising from the movement of the main stream of humidified air, induced by the core plates 4 located above the upper and below the lower discs.

3, are introduced into this stream beyond the edge of the discs 3, as a result of which the droplets are completely evaporated and the air is moistened. In the surrounding space, humidified air is supplied through the air outlet guide elements 10 in the form of a full fan.

Thus, a more finely dispersed, easily dispersed air stream of droplets is achieved in the device due to the throttle effect when spraying water, which improves the efficiency of air humidification, while this effect is achieved while simplifying the design and reducing the mass and size characteristics of the device.
