Abstract

The invention provides a novel thermodynamic vacuum deaeration system. The novel thermodynamic vacuum deaeration system comprises a softened water tank (10), a softened water pump (20), a coal economizer (40), a deaerator water feeding pump (30), a deaerator (50) and a vacuum ejector (60); a vacuum ejection pipeline for carrying out pressure reduction on the deaerator is connected to the softenedwater tank (10), the softened water pump (20), the vacuum ejector (60) and the deaerator (50); and a water injection pipeline for injecting water into the deaerator is connected to the softened watertank (10), the deaerator water feeding pump (30), the coal economizer (40) and the deaerator (50). The thermodynamic vacuum deaeration system has the advantages of being good in energy saving performance, high in working efficiency, good in waste heat recovery function and the like.

Description

technical field [0001] The invention relates to the field of industrial and civil waste heat recovery, in particular to a novel thermal vacuum oxygen removal system. Background technique [0002] At present, the commonly used deaeration method for boiler feed water is atmospheric thermal deaeration. Atmospheric thermal deaerators require about 20% of their own steam consumption. In addition, a large number of valve groups such as pressure reducing valves, safety valves, and flow regulating valves need to be installed for the deoxygenated steam, which increases the construction cost. [0003] To sum up, the following problems exist in the prior art: the atmospheric thermal deaerator consumes a large amount of steam and is expensive. Contents of the invention [0004] The invention provides a novel thermal vacuum deaeration system to solve the problems of large steam consumption and high cost of a gas-type thermal deaerator. [0005] For this reason, the present invention...
