Nedog tan oii of a known device for heat and mass exchange apparatus is the intensity of heat and mass transfer, the possibility of creating a targeted collision of pulsating gas-liquid jets and, therefore, turbulent mode with an intensively updated surface of phase contact, as well as the complexity of the valve design.

The circuit of the invention is the intensification of processes for the collision of pulsating gas-liquid-liquid jets during the creation of acoustic oscillations in a gas-liquid flow and the simplification of confusion.

The goal is achieved by the fact that in a known 1 ontact device, including a base with openings, a valve with a closed cavity and openings, the base is made in the form of a tubular serpentine plate, and the valve is in the form of a tubular coil with lower and coaxially - upper holes of diameter. The tubular valve coil is a resonating cavity and is made with a radius of curvature identical to a tubular serpentine plate. The valve closes the slots of the serpentine seal and simultaneously is the pulse of the era.

A distinctive feature of the proposed contact device for heat and mass transfer devices is the location over the heat exchange tubular serpentine bladder of another tubular coil g with the same radius of curvature and with the resonating cavity, which simultaneously plays the role of a valve. With the passage of the gas-liquid mixture through the resonating cavity of the valve, high-frequency oscillations in the gas flow and vibration of the valve are created. At the same time, the width of the gap gaps between the valve and the heat exchanging plate varies, which creates pulsating gas-liquid flows followed by their collision. Ultimately, this contributes to the enhancement of the vortex flow turbulization of the gas-liquid layer and intensifies the process of heat and mass transfer.

FIG. 1 shows a contact device, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

The contact device for heat and mass transfer apparatus consists of a base,

made in the form of a coil tubular plate 1, above which is mounted a valve 2 with the bottom 3 and top 4 ports. The valve is made in the form of a tubular coil with a resonating cavity 5 overlaps the gap gaps 6 of the heat-exchange coil plate 1, being a resonator. A liquid dispenser 7 is installed in the center of the contact device.

Contact device operates as follows.

Liquid is supplied to the contact device through the distributor 7. Gas (steam) is fed from the bottom up. When passing through the gaps 6, the lower 3 and upper 4 holes of the resonating cavity 5 create intense acoustic vibrations, which contributes to the vibration of the tubular coil 1 acting as a valve.

As a result of the vibration, the width of the gap between the valve 2 and the heat exchange plate 1 varies, which contributes to the creation of pulsations of gas-liquid flows, their targeted collision and the intensification of heat and mass transfer.

A known valve plate for mass transfer apparatuses, comprising a base with openings and plate valves arranged above them with reflectors in the form of a coil of a flat helix.

The disadvantage of such a dish is that the reflectors change the direction and deferm. They create a gas-liquid flow, however, a targeted collision of pulsating jets and a high-turbulent regime on the dish cannot be achieved.

Conducted bench tests showed high efficiency of the proposed contact device for heat-mass-exchange apparatus.
