FOAM MASS-TRANSFER AND HEAT EXCHANGE UNIT Russian patent published in 2017 - IPC B01D47/04 

FIELD: heating system.

SUBSTANCE: foam mass-transfer and heat exchange unit is proposed, it comprises a body with gas inlet and outlet nozzles and a working fluid inlet; a group of lattices horizontally installed inside the body at its height, dividing the inner cavity of the body into sublattice and superlattice zones; a vertical closed partition installed inside the body coaxially with it, forming an annular channel between it and the cavity body for draining the working fluid. Lattices are fixed along the perimeter of the inner surface of the partition, and the upper end of the partition is located above the upper grid and serves as its overflow threshold; a gas supply pipe having a rectilinear portion extending vertically downward along the axis of the housing through all the lattices; a spray separator located in the superlattice zone, a discharge chamber of the working fluid with a branch pipe for the discharge of the spent working fluid. In the sublattice zone, a heat exchange surface is provided in the cavity formed by the lower lattice and the partition, with inlets and discharge tubes of the coolant located outside the body, and the lower end of the partition is located below the heat exchange surface; in addition, a temperature sensor is built into the drain chamber of the working fluid, and a coolant flow controller, controlled by signals from the temperature sensor.

EFFECT: treat gas heat energy utilisation control with a pure coolant directly in the foam unit.
