Connect the hot well of condensation chamber, the bubbling disk positioned at downpipe lower part be equipped with the hot well, be equipped with the hot well every
Hot well is divided into left and right two Room by plate, the partition plate, communicating pipe passes through partition plate, connects the left and right room of hot well, the left room of hot well
Bottom, which is equipped with, condenses water out；
Spray module is set in the steam exhaust input chamber；
Bubbling component is set in the right ventricle of the hot well.
The spray module includes a cylindric water inlet pipe, if the top on the outside of the water inlet tube wall sets involvement
Lead to its internal nozzle, the right end of the water inlet pipe is equipped with water inlet.
The bubbling component includes a cylindric steam inlet pipe, and the both sides of the steam inlet pipe set some cylindrical shapes respectively
Bubbling pipe, one end connection steam inlet pipe of the bubbling pipe, the other end closing of the bubbling pipe, on the tube wall of the bubbling pipe
Equipped with some fishbone shape through holes.
The fishbone shape through hole is cross-shaped through hole.
During work, demineralized water is entered by the water inlet pipe of spray module, due to the effect of nozzle so that demineralized water is defeated in steam exhaust
Enter indoor fully atomization, carry out sufficient heat exchange between the steam exhaust of demineralized water and the steam turbine discharge of spray pattern, then remove
Brine enters hot well with steam exhaust mixture, flows into bubbling disk first, and from the surrounding sprinkle of bubbling disk, be delivered in steam inlet pipe
Steam is outwards sprayed by fishbone shape through hole on tube wall, and demineralized water and steam exhaust mixture are fully disturbed, and is further removed
Dissolved oxygen therein, so far so that the condensation water dissolved oxygen of discharge further reduces.
The present invention can effectively reduce the dissolved oxygen in condensation water, reach on the premise of excessive fund input is not increased
Extend service life of equipment, reduce the purpose of equipment failure rate.
