Abstract
The pre- deoxidation method of boiler water of the present invention, comprises the following steps：1) the benzenediol aqueous solution is prepared；2) by step 1) the benzenediol aqueous solution be added in pans；3) when the steam condensate that process units is produced enters pans, the benzenediol aqueous solution and the oxygen reaction contained in steam condensate, until the oxygen contained in steam condensate is exhausted.The present invention can remove the dissolved oxygen that steam condensate contains, it is to avoid produce corrosion to pipeline, pump and storage tank because steam condensate contains dissolved oxygen, improve the service life of pipeline, pump and storage tank, water quality is ensured while improving.
Description
Technical field
The present invention relates to chemical products technology of preparing, esterification technical field is specifically designed, specifically, its displaying is a kind of
The pre- deoxidation method of boiler water.
Background technology
Boiler is the conventional infrastructure device of esterification, and it is used as esterification container；During boiler use, production dress
The steam condensate (exhaust steam water) for putting generation squeezes into intermediate tank storage through pump, then is delivered to oxygen-eliminating device and boiler, steam through multistage pump
The temperature of lime set is general at 90 DEG C, PH=6--6.5, and containing dissolved oxygen；
Steam condensate perishable pipeline, pump and storage tank in the state of containing dissolved oxygen, reduce making for pipeline, pump and storage tank
With impeller is used in life-span, particularly multistage pump, its replacement frequency is high, increases the production cost of enterprise.
Therefore, it is necessary to provide a kind of pre- deoxidation method of boiler water to solve the above problems.
The content of the invention
It is an object of the invention to provide a kind of pre- deoxidation method of boiler water, it can remove the dissolved oxygen that steam condensate contains,
Avoid producing corrosion to pipeline, pump and storage tank because steam condensate contains dissolved oxygen, improve the use longevity of pipeline, pump and storage tank
Life, water quality is ensured while improving.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of pre- deoxidation method of boiler water, comprises the following steps：
1) the benzenediol aqueous solution is prepared；
2) by step 1) the benzenediol aqueous solution be added in pans；
3) when the steam condensate that process units is produced enters pans, the benzenediol aqueous solution and the oxygen contained in steam condensate
Solid/liquid/gas reactions, until the oxygen contained in steam condensate is exhausted.
Further, step 1) in, in the benzenediol aqueous solution, benzenediol concentration is 3-7%.
Further, step 1) preparation process for benzenediol is added in hot water, controlled concentration is 4-6%, uniformly
After stirring, the benzenediol aqueous solution is obtained.
Further, step 2) be that via by measuring after pump-metered, step 1 is added to pans) in benzenediol water
Solution, control pans reclaimed water is to hydroquinones content 5-6PPM.
Compared with prior art, the pre- deoxidation method of a kind of boiler water of the invention, it is molten that it can remove that steam condensate contains
Solve oxygen, it is to avoid corrosion is produced to pipeline, pump and storage tank because steam condensate contains dissolved oxygen, making for pipeline, pump and storage tank is improved
With the life-span, water quality is ensured while improving.
