The scale inhibitor for salt manufacture, disclosed by the invention, issuitable for the salt and Glauber salt co-production industry, as well as sugar manufacture and monosodium glutamate manufacture industries, can prevent a heat exchange tube in a pre-heater and a heat chamber from scaling, and guarantees the scale inhibitor with heat transfer effect for salt manufacture.
Description
Technical field
The present invention relates to the dirt dispersion agent field, specifically relate to a kind of salt manufacturing Scale inhibitors and application thereof.
Background technology
The raw material of bittern salt manufacturing is mainly from seawater and subsurface brine, and its salt producing craft adopts the bittern purifying method to remove calcium, magnesium ion in the former halogen mostly, but Ex-all fully.Still lingering section calcium, magnesium ion in the bittern after the purification, and purify back bittern and be alkalescence.In the subsequent evaporation operation, along with the continuous evaporation concentration of bittern, the calcium in the bittern, magnesium ion concentration also constantly increase, and form the fouling precipitation easily at evaporating pot and heating chamber, and this directly causes heat transfer rate to reduce, and process energy consumption increases, and the production cycle shortens.In the prior art, generally adopt to add the anti-locking apparatus fouling of mode that bittern PH is regulated in acid, but this kind mode is quite serious to the corrosion of equipment, the device scale formation is still fairly obvious.
Summary of the invention
At some problems that exist in the prior art, one of purpose of the present invention is: a kind of heat transfer tube fouling that can prevent in preheater and the heating chamber is provided, guarantees the salt manufacturing Scale inhibitors of heat-transfer effect; Another object of the present invention is to: the application of salt manufacturing Scale inhibitors is provided.
For achieving the above object, the present invention adopts following technical scheme to realize:
The salt manufacturing Scale inhibitors, by weight percentage, the vinylformic acid-acrylate by 25～30%-sodium allylsulfonate multiple copolymer, 40～50% poly aspartic acid, 10～15% Sunmorl N 60S and 5～10% water make; Weight percent hundred sums of all components are 100%.
Described vinylformic acid-acrylate-sodium allylsulfonate multipolymer is for by quality ratio: Bing Xi Suan ︰ Bing olefin(e) acid Zhi ︰ sodium allylsulfonate is 5 ︰, 1.2 ︰ 3;
