FIELD: chemical engineering. ^ SUBSTANCE: thermal deaerator suitable for degassing of water comprises: heat exchangers; deaeration column connected with connecting pipes serving for supplying water and heat carrier and for discharging steam-air mixture and deaerated water; and multistep steam generator mounted in the same casing with deaeration column. Steam-water mixture-discharge pipe is connected to gas inlet of water-jet ejector functioning as control means in steam generator liquid inlet of water-jet ejector is connected to inlet pipe serving for passage of chemically cleaned water into deaeration stage and outlet pipe of water-jet ejector is connected to vessel having (i) connecting pipe for communication through hydraulic gate with water-supply connecting pipe in column and (ii) air-discharge connecting pipe. Steam generator consists of circuits in -series installed in the travel direction of water fed into deaeration stage. The circuits include heat exchangers, to which heat carrier is passed. Column includes reflecting sheets and perforated sheets. ^ EFFECT: increased degree of water degassing and enabled control of thermodynamic condition of degassing. ^ 3 dwg |
