LINEAR STRUCTURE-TYPE THERMAL DEAERATOR Russian patent published in 2007 - IPC C02F1/20 

FIELD: heating engineering.

SUBSTANCE: invention relates to thermal deaerators that can be used in technical field wherein industrial treatment of water, industrial effluents, and aqueous solutions is employed. Apparatus has jet chamber provided with hydraulic gate constructed in the form of perforated flanged tray positioned horizontally between partitions under grid and over evaporator. Hydraulic gate is provided with drainage steam canal communicating tube space of evaporator with jet chamber space and is constructed in the form of at least one tube mounted vertically in tray close to partition on the side of connecting pipe through which water to be treated is supplied to water-distribution perforated shelf of jet chamber. Hydraulic gate isolates a zone of evaporator tube space into separate site of final deaeration step with minimum gases in secondary water steam generated upon boiling.

EFFECT: increased driving force of the process owing to generated secondary steam introduced increased degree of deaeration.
