US 2021/0331089 A1 · DEAERATOR FOR THE EVACUATION OF GASES IN FLUID BASED HEAT EXCHANGE SYSTEMS

Abstract

Deaerator (1) for the removal and evacuation of gases in heating systems or the like, comprising air expulsion means (2; 4), a container body (10) provided with a cavity (100) inside which a heat transfer fluid passes and circulates, the container body (10) comprising at least one degassing chamber (101), at least one inlet duct (11), wherethrough the heat transfer fluid enters, at least one outlet duct (12), wherethrough the heat transfer fluid exits, the inlet (11) and outlet (12) ducts being in fluid communication with the cavity (100), characterised in that: it comprises, inside the cavity (100), at least one flow diverter adapted to divide the flow (F) of the heat transfer fluid into a primary flow (Fp) and into a secondary flow (Fs); the flow diverter (14) being positioned in the cavity (100) so as to define, in cooperation with the walls of the cavity (100) and/or of the container body (10), at least the degassing chamber (101), inside which the secondary flow (Fs) passes, and at least one passage chamber (102), inside which the primary flow (Fp) passes, the degassing chamber (101) being dedicated to the interception and evacuation of the air, and the passage chamber (102) being dedicated to the passage of the flow of the heat transfer fluid not subject to degassing; the degassing chamber (101) being adapted to slow down the speed of the secondary flow (Fs), by an increase in the passage section, favouring the separation of air from the same flow (Fs).

Dependent claims

A deaerator for removal and evacuation of gaseous substances from fluid circulating in a fluid based heat exchange system, the deaerator comprising:

a container body having internal walls defining a cavity within the body;
at least one inlet duct in fluid communication with the cavity, for inflowing heat exchange fluid to the cavity;
at least one outlet duct in fluid communication with the cavity for outflowing heat exchange from the cavity;
at least one flow diverter disposed within the cavity, the flow diverter in cooperation with the cavity walls, dividing the cavity into at least a degassing chamber and a passage chamber;
the flow diverter having an inlet edge disposed at or adjacent to the inlet duct defining a degassing chamber entry having a cross-section, the degassing chamber having in at least a portion thereof a cross section larger than the degassing section entry cross section;
the inlet edge being disposed and oriented to divide heat exchange fluid flow from the inlet duct to a primary flow directed to the passage chamber and a secondary flow directed to the degassing chamber;
a merging opening between the passage chamber and the degassing chamber, the merging opening disposed distally to the degassing chamber entry along the passage chamber and the degassing chamber, to permit merging of the primary of the primary and secondary flows after the respective flow traversed at least a portion of the respective chamber, the merging opening further disposed to permit the merged flow to exit the body via the outlet duct;
and,
at least one gas expulsion device in fluid communication disposed in fluid communication with an upper section of the degassing chamber.
