Abstract
The invention relates to a descaling anticorrosion agent of a filter device. The descaling anticorrosion agent is organic polybasic phosphonic acid. The descaling anticorrosion agent is characterized in that the organic polybasic phosphonic acid is organic polybasic phosphonic acid, wherein a PO3H2 group and a COOH group are used for resisting the scaling and preventing the corrosion of the water filter device, water scales of CaCO3, CaSO4 or CaSiO3 can be inhibited and dissolved, and the high-hardness, high-alkalinity, high-chloride and high-temperature water scales can be inhibited and dissolved; moreover, the manufacturing process is simple, the cost is low, and the descaling anticorrosion agent is harmless to the human body.
Description
Technical field
The present invention, relevant for water treating equipment field, particularly provides the chemicals of scale removal corrosion protection to filtering purifying equipment.
Background technology
Water treatment industry can be divided into: product manufacture, service and three parts of system Construction.Wherein, product manufacture comprises water treating equipment and water treatment agent manufacture.And due to the material of equipment and water conditioner with Chemical Composition, therefore after life-time service, can on equipment, there is incrustation scale, or corrosion, affect the normal use of equipment, and Water quality caused to negative impact.
Incrustation scale is generally by CaCO
3, Ca
3(PO
4)
2, CaSO
4, the slightly soluble salt such as Calucium Silicate powder (magnesium) forms.The solubleness of these salt is very little, as 0 ℃ time, and CaCO
3solubleness be 20mg/L, Ca
3(PO
4)
2solubleness only have 0.1mg/L, and their solubleness reduces with the rising of pH value and water temperature, therefore especially easily at the high heat transfer position of temperature, reach hypersaturated state and crystallization, when flow velocity is less or heat-transfer surface is more coarse, these crystallizations are just easily deposited on and on heating surface, form incrustation scale.
The method of common descale is from water, to remove incrustation ion, comprises ion exchange method and lime softening method etc., or acid adding or logical CO
2, reduce pH, stablize hydrocarbonate.These methods, when removing incrustation scale, have been introduced other corrosives, adding also of heavy metallic salt Water quality are exerted an influence simultaneously.
Therefore need to provide a kind of protective material that helps equipment to carry out scale removal corrosion protection, said preparation should be able to provide long-term protection and corrode littlely, and harmless water treating equipment, and its manufacture method should cost is low, environmental friendliness.
Summary of the invention
For addressing the above problem, the invention provides a kind of filter plant scale removal inhibitor, it is organic multicomponent phosphonic acids, wherein: described organic multicomponent phosphonic acids is organic multicomponent phosphine carboxylic acid, and PO wherein
3h
2to described water filtration device, provide scale inhibition and corrosion protection effect with COOH group.
Filter plant scale removal inhibitor provided by the present invention, its group can play obvious removal effect to the incrustation scale on filter plant, and meanwhile, it has avoided the corrosive nature to equipment such as inorganic salt, is beneficial to same main equipment to share; And resolvent is to human body toxicological harmless.
Embodiment
The invention provides a kind of filter plant scale removal inhibitor, it is organic multicomponent phosphonic acids, it is characterized in that: described organic multicomponent phosphonic acids is organic multicomponent phosphine carboxylic acid, and PO wherein
3h
2to described water filtration device, provide scale inhibition and corrosion protection effect with COOH group.Because said preparation has PO
3h
2with COOH group, so energy and Ca
2+, Mg
2+deng metal ion, form the stable complex compound of various compositions.
Preferred organic phosphine carboxylic acid salt is: 1,1, and-bisphosphate propionyloxy sodium phosphate (BPBP), and to CaCO
3, CaSO
4, CaSiO
3deng all, there is good inhibition and solublization, also fine to the rust inhibition of carbon steel.Its structural formula is:
Preferred organic phosphine carboxylic acid salt is: 2-phosphate butane-1, and 2,4-tricarboxylic acid (PBTCA), it can be in high rigidity, and high alkalinity is used under high cl content and high temperature.Its structural formula is:
Filter plant scale removal inhibitor provided by the present invention, its group can play obvious removal effect to the incrustation scale on filter plant, and meanwhile, it has avoided the corrosive nature to equipment such as inorganic salt, is beneficial to same main equipment to share; And resolvent is to human body toxicological harmless.
Water treatment flocculant provided by the present invention, because adopt the polymer substance of certain micro-organisms secretion to make flocculation agent, there is safety and environmental protection, can from physical environment, obtain, the simple feature of the low technique of cost, simultaneously because employing microbial technique therefore in use can natural degradation.
