Abstract

The invention belongs to the technical field of industrial steam recycling, in particular to a recovery system of oxygen-enriched flash steam. The recovery system of oxygen-enriched flash steam comprises a thermal deaerator. A water inlet pipe of the thermal deaerator is connected with a water source which is supplied to desalted water, and a water using pipe of the thermal deaerator is connectedwith a boiler. A steam discharging pipe of the thermal deaerator is connected with a steam-water separator through a hollow ejector. A drain pipe of the steam-water separator is connected with a hot water pump, and the steam discharging pipe is connected with the hot water pump through a spraying equipment. A water outlet pipe of the hot water pump is connected with the thermal deaerator. Comparedwith the prior art, heat energy and water sources of oxygen-enriched flash steam loss caused by air discharge are recycled, and is returned to the thermal deaerator for cyclic utilization, so that the waste of energy and resources is avoided.

Description

technical field [0001] The invention belongs to the technical field of recovery and utilization of industrial steam, and in particular relates to a recovery system for oxygen-enriched flash steam. Background technique [0002] Many industrial enterprises need the steam produced by the boiler equipment to be heated at low temperature. The boiler system has a special boiler water supply system. Although the boiler water supply has been treated by softening or desalting methods to prevent the heating surface of the boiler from scaling, the water still contains oxygen and carbon dioxide. Other gases, of which oxygen is a major depolarizer, its presence will promote the internal corrosion of the metal surface of the filter equipment and thermal system. This kind of corrosion is usually localized ulcer corrosion. In severe cases, the boiler equipment will be perforated, thereby affecting the safety and service life of the filter equipment and thermal system operation. Therefore, ...
