Description
Technical field
The invention belongs to industrial circulating cooling waters, technical field of sewage, and in particular to a kind of novel increasing of sodium hypochlorite
Imitate the preparation and utilization of agent.
Background technique
After the extensive utilization of recirculated water, new project is also constantly showed, and recirculated water recycles, not only concentration times
Number increases, while microorganism, algae also constantly breed, and in recirculated water, very great chemical industry, steel, papermaking enterprise are using secondary
The oxidizing bactericide containing sodium hypochlorite such as sodium chlorate, but this kind of conventional matter is particularly easy to decompose, and lose activity, it is furthermore secondary
The impact type of sodium chlorate is added, and a large amount of hypochlorous acid of abrupt release, hypochlorous acid has stronger corrosivity to carbon steel or stainless steel,
A large amount of long-term corrosion that will cause pipe-line equipment, cause economic loss, at present in the world, generally use sodium hypochlorite and sea
Because substance is reacted, the halide of glycolylurea substance is generated, solid is finally prepared into, is directly appended to recirculated water or swimming pool
In, the effect of sterilizing is got, the production of halogenated hydantoin substance belongs to dangerous technique, and preparation is taken a lot of work arduously, and it is with high costs,
Expensive problem, thus it is proposed that a kind of preparation and utilization of the agent of sodium hypochlorite Novel synergistic.
Summary of the invention
The purpose of the present invention is to provide the preparations and utilization of a kind of sodium hypochlorite Novel synergistic agent, to solve above-mentioned background
The impact type of the sodium hypochlorite proposed in technology is added, a large amount of hypochlorous acid of abrupt release, and hypochlorous acid is equal to carbon steel or stainless steel
There is stronger corrosivity, a large amount of long-term corrosion that will cause pipe-line equipment cause economic loss, at present in the world, generally
It is reacted using sodium hypochlorite with glycolylurea substance, generates the halide of glycolylurea substance, be finally prepared into solid, be directly appended to
In recirculated water or swimming pool, the effect of sterilizing is got, the production of halogenated hydantoin substance belongs to dangerous technique, and preparation takes
Expenses of labour power, problem with high costs, expensive.
To achieve the above object, the invention provides the following technical scheme: a kind of preparation of sodium hypochlorite Novel synergistic agent and
With glycolylurea substance is carried out special activating process activation processing by the present invention, directly that the glycolylurea substance after activation is direct
Instantaneous touch, fast reaction in online mixer with sodium hypochlorite, allow chlorine element from be transformed into conjunction with sodium hypochlorite with sea
Because substance combines, moment produces chlorination glycolylurea substance, and chlorination glycolylurea substance can be acted on water, and it is anti-that slowly hydrolysis occurs
It answers, generates hypochlorous acid, this mode can constantly release for a long time and a small amount of hypochlorous acid, in this way by chlorine element anchor
Get up calmly, get the effect of " reservoir ", to play the effect of sterilization, while reducing the usage amount of sodium hypochlorite, reduce at
This, sodium hypochlorite plays the role of the anti-algae of sterilization by discharging hypochlorous acid, and since the impact type of sodium hypochlorite adds, moment can be released
The hypochlorous acid of the hypochlorous acid of amplification quantity, high concentration can cause fatal corruption to the pipeline of pipeline carbon steel material or stainless steel material
Erosion, causes greatly to waste, and sodium hypochlorite and glycolylurea substance hybrid reaction in online mixer are generated chlorination by the present invention
Glycolylurea substance, the sodium hypochlorite for reducing moment discharges hypochlorous impact type corrosion, to reduce adding for sodium hypochlorite
Add the corrosion to carbon steel material or stainless steel material system, by stablizing the free chlorine element in water system, is carried out by " demand "
Hypochlorous acid is discharged, achievees the effect that efficiently to sterilize for a long time.
