Description

The invention relates to the technique of air conditioning, namely the design of the nozzles of heat and mass assemblies used as contact devices during tagging and mass transfer processes, and is an improvement of the invention according to the authors. St. S 922489.

The purpose of the invention is to increase the reliability of work.

FIG. 1 is a schematic diagram of the nozzle of the heat and mass transfer apparatus; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows bit bb in fig 1.

The nozzle of the heat and mass transfer apparatus contains longitudinal threads 1 and main and additional transverse threads 2 and 3 (Fig. 1).

The longitudinal threads 1 of the first row and the main transverse threads 2 lie and are attached to each other at their contact points. The additional transverse threads 3 abut and are attached to the longitudinal threads 1 of the second row. In addition, the main and Additional threads 2 and 3 are adjacent and attached to each other in the places of their contact. The intersections of transverse lines 2 and 3 with each other do not coincide with the places of their intersections with the longitudinal, nit -, and 1 (Figs. 2 and 3).

The main and additional transverse threads 2 and 3 installed at an angle to each other are supporting and distant for longitudinal threads: 1. The pitch of the main transverse threads 2 and their angle to the longitudinal threads 1 is determined by the number of supports for the longitudinal threads 1 first p yes. The same pitch and angle of inclination of the additional transverse threads 3 provides the necessary number of supports for the longitudinal threads 1 of the second row.

Intersecting and leaning on each other, the main and additional threads 2 and 3 form a distance grid between adjacent rows of longitudinal threads 1, with the distance between adjacent rows of longitudinal threads 1 being twice as large as in the case of

the locations between the longitudinal threads 1 are one row and the cross threads 2.

The nozzle heat and mass transfer apparatus operates as follows. The raw air enters the channels formed by the longitudinal threads 1 and is processed by contact with the surfaces of these threads 1.

The size of the nozzle channels is defined. In particular, the distance between the longitudinal filaments 1 in adjacent rows, which depends on the diameter of the base and additional transverse filaments 2 and 3. The lattice arrangement of the transverse strands 2 and 3 provides an increase in these channels, resulting in particles and other extraneous inclusions contained in the treated air are less likely to encounter filaments 1, 2, and 3 and are less deposited on them.

With brl of thicker films of irrigating fluid flowing along longitudinal threads 1, the nozzle channels are sufficiently passable for contaminating particles due to the increased distance of longitudinal threads 1.

When air moves along the longitudinal threads 1, their intersection (contiguity) with cross threads 2 and 3, as well as the latter, between themselves form possible places of sedimentation of particles from the air.

As a result of the fact that the spacing of the main and additional threads 2 and 3 is significantly larger than the pitch of the longitudinal threads 1, the number of crossings of the cross nnty 2 and 3 between them is significantly less than their intersections with the longitudinal threads g-m 1. In addition, the intersection data They are made without coincidence with each other, therefore, the intersections of the transverse filaments 2 and 3 between each other are well blown by the air flow, which leads to a decrease in the precipitation of particles and other inclusions. With the corridor arrangement of the longitudinal threads 1 in the adjacent rows between the longitudinal and transverse threads lj-3 there is a gap. (Fig. 3), which also contributes to the better blowing of the contact points of the Tety-1-3 between them

NOZZLE HEAT AND MASS EXCHANGE DEVICE on ed. St. No. 922489, characterized in that, in order to increase the reliability of operation, additional transverse threads with the same diameter and angle to the longitudinal threads as the main transverse threads are installed in the apparatus, the main and additional transverse threads being located so that their contact points between themselves and with the longitudinal threads are in different planes, and additional transverse threads are inclined to the longitudinal threads in the opposite direction relative to the main transverse threads.
