After dynamic, in the presence of turbine centrifugal power, liquid makees radially operation from impeller central to periphery, when liquid from impeller central get rid of to
While periphery, impeller central forms low-pressure area, in the presence of chemical tank liquid level and the total potential energy difference of impeller central, in chemical tank
Sodium sulfite, cobalt chloride hexahydrate solution and one-level deoxygenation waterpipe Inner water intake impeller, by chemical reaction, reach two
The purpose of secondary deoxygenation.
Oxygen in sodium sulfite and boiler water reacts, and generates sodium sulphate：2Na2SO3 + O2 == 2Na2SO4
It is relatively low for spring, water temperature in winter because Water Temperature the deaerating effect of sodium sulfite, sodium sulfite deaerating effect
Difference, the problem of excess quantity is high, with cobalt chloride hexahydrate catalyst, accelerate Na2SO3With the reaction speed of oxygen in water, alleviate
Water temperature is low, and the problem of chemical agent deaerating effect difference, reasonably control in 3~5mg/l, reduces sulfurous acid to sodium sulfite excess quantity
Corrosivity of the sodium to boiler.
The beneficial effects of the utility model are：Suitable for oil field high pressure injection steam boiler water water treatment, make boiler water oxygen-containing
Amount reduces, and sucks technology, the transparent flowmeter metered doses of medicament of glass rotors using negative pressure, easy to operate, metering is accurate, slows down boiler
Corrosion, prolonged boiler service life, ensure oilfield safety production.
