Abstract
A water treatment of boiler is carried out by chemically examining various water indexes and computing concentration of water treatment chemical. The water treatment chemical consists of sodium hydrate, monometallic sodium orthophosphate, hydroxyl-ethylene phosphoric acid, ethylenimine, hydrazine, sodium humate, sodium sulfite, sodium phosphate and deionized water. It is simple, cheap and non-toxic.
Description
Technical field
The invention belongs to chemical industry with the field, relate to the method for water treatment, more particularly, the present invention relates to a kind of water technology of boiler.
Background technology
Boiler is the indispensable energy supplyystem of industrial system, and the equipment material of boiler systems generally is different from other industrial cycle equipment, and its easier comparatively speaking fouling, often needs clean.And the dirty matter and the corrosion product that exist in the boiler all are different from other industrial equipmentss.Therefore,, not only need special water conditioner, also need a kind of at water technology at boiler systems at boiler systems in order effectively boiler to be cleaned and water treatment.
The inventor has developed the water treating agent for boilers of being made up of polycomponent through further investigation, and corresponding boiler water processing technology.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of water technology of boiler, it is characterized in that, comprises following steps:
(1) basicity, hardness, dissolved oxygen, saltiness, the iron-holder index of chemical examination dosing mouth place water calculate the concentration of the water conditioner that must add then;
(2) with dosing pump and water pump interlock, with the deoxygenation mouth of boiler or softened water tank exit end as dosing mouth, add water treating agent for boilers, it is made up of sodium hydroxide, SODIUM PHOSPHATE, MONOBASIC, 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid, hexahydroaniline, diamine, sodium humate, S-WAT, tertiary sodium phosphate, deionized water;
(3) various controlling index and the drug concentration that must survey a boiler for the previous period every 4 hours after the dosing be done some adjustment to dosing speed again according to result of laboratory test, and definite blowdown frequency, treat all normal after, monitor boiler routinely.
Further, in the water technology of boiler of the present invention, the proportioning of described water treating agent for boilers is as follows:
Sodium hydroxide: 3-4%
SODIUM PHOSPHATE, MONOBASIC: 1-2%
1-Hydroxy Ethylidene-1,1-Diphosphonic Acid: 15-20%
Hexahydroaniline: 5-7%
Diamine: 4-6%
Sodium humate: 0.1-1%
S-WAT: 1-3%
Tertiary sodium phosphate: 2-3%
Deionized water: 60-70%.
Boiler water processing Technology of the present invention is simple, and used cost of material is cheap, and is nontoxic, is a kind of very practical boiler water processing method.
Embodiment
When carrying out water treatment, at first chemically examine basicity, hardness, dissolved oxygen, saltiness, the iron-holder index of dosing mouth place water, calculate the concentration of the water conditioner that must add then, according to the flow of service pump, adjust the dosing speed of dosing pump.As boiler be furnished with deoxygenator then dosing mouth should be located at the exit end of deoxygenation mouth, if no deoxygenator then dosing mouth be located at the exit of softened water tank, and dosing pump and service pump are linked.
Various controlling index and the drug concentration that must survey a boiler for the previous period every 4 hours after the dosing be done some adjustment to dosing speed again according to result of laboratory test, and definite blowdown frequency, treat all normal after, can monitor boiler routinely.
Claims (2)
1. the water technology of a boiler is characterized in that, comprises following steps:
