Description

The invention relates to air conditioning technology and allows to intensify the process of heat and mass transfer and reduce the size of the device. The housing 1 is made in the form of a cochlea, the inlet of which serves as an inlet for air, the upper end - with an outlet for 3, the lower end with a collector 4 of liquid. At the same time, the centrifugal nozzle 5 is installed in the “housing 1 at the same angle with k'-. similar to the housing 1 at the point of installation of the nozzle 5. The direction of the roller of the first nozzle 5 coincides with the direction of air movement, and the other opposite to it. The air, acting on the air pipe, twists, while contacting with water, spray nozzle

5. Due to the high rate of swirling of the flow, high dispersion and turbulization of the water-air mixture are obtained, and, consequently, intensive heat and mass transfer. Simultaneously with mixing

centrifugal separation of water and air occurs, the air after contact with water moves to the outlet nozzle 3, and the water to the liquid tee collection 4 and is removed through the drain patra · side. 3 il.

The invention relates to air conditioning technology, in particular to apparatus for heat and moisture treatment of air.

The purpose of the invention is to intensify the process of heat and mass transfer and reduce the overall dimensions of the devices,

Fig, 1 shows a device for heat and moisture treatment of air; figure 2 is a view of And figure 1; on fig.Z - section bb in figure 1.

The device for heat and humidity treatment of air contains a vertical housing 1 with nozzles of inlet 2 and 25 of air outlet 3, a collector 4 of liquid. and located inside the housing 1 by centrifugal nozzles 5..

The housing 3 is made in the form of a cochlea, the inlet of which serves as an inlet pipe 2 for air, the upper end of the tube · an outlet pipe 3, the lower end - a liquid collector 4, while the centrifugal nozzles 5 are installed in the case

I at the same angle 6 with a tangent to the housing 1 at the point of installation ^ 5 nozzle 5, and the direction of the first spray along the air nozzle 5 coincides with the direction of air movement, and the other opposite to it. The outlet nozzle 3 is provided with a shell 7, which forms an annular gap with the inner surface of the nozzle 3.

The fluid collection 4 is provided with a cone-shaped cap 8 with holes 9 in the upper part and radial partitions 10, and a pipe

II to remove water. Water to the nozzle 5 is supplied through the supply pipeline 12. 50

The device works as follows.

The air flow, entering the housing 1, twists and contacts with water sprayed by centrifugal-55 'nozzles 5. At the same time, aerodynamic pressure at a speed of ν = 20 ~

25 m / s allows you to get high

dispersion due to the additional crushing of water droplets (except the addition of spray nozzles 5 when sprayed) and significant turbulization of the water-air mixture, and, consequently, intensive heat and mass transfer. Simultaneously with the mixing in the housing 1 occurs centrifugal separation of water and air, ha. The air after contact with water moves up to the nozzle 3. The annular gap between the shell 7 and nozzle 3 prevents the upper part of the water layer from being expelled into the nozzle 3 along the inner surface of the housing 1. Water deposited on the inner surface of the housing 1 enters the liquid collection 4, enlarged the internal cross section of which contributes to the removal of a layer of water slowing down in rotational movement outside the zone of action of air flow. In the collection of 4 fluid using radial partitions 10, the rotational movement of water is converted into translational and it is drained through the pipe 11.

In the collection of 4 liquid residues air. ha, contained in the stream of outgoing water, are separated from it, floating up under the action of hydrostatic forces. The cap 8 protects from the drift of water droplets formed by the discharge in the axial zone of the device. Holes 9 in the cap 8 contribute to the equalization of pressures in the central and peripheral zones of the liquid collector 4 and ensure the release of air released from. water under the cap 8,
