Description
Technical field
The present invention relates to soft brush treatment technical fields, and in particular to a kind of to be used to remove removing calcium and magnesium by what PAC flocculant made
The preparation method of the resin of silicon.
Background technique:
The mineral compositions such as calcic, magnesium, silicon are more in water body, and the hardness of water is bigger.This hard water use is in boiler or steaming
On locomotive, the soft dirt of one layer " hard scale " or one layer of calcium carbonate can be formed on boiler bottom and duct wall, boiler operatiopn is long
, a large amount of scales will be deposited in its inner wall, due to having the boiler heat-transfer performance depreciation of scale, will affect the cooling of boiler tube,
The temperature difference of heating surface two sides is caused to increase, furnace tube temperature rises.To make tube wall overheating deforming, under the action of boiler pressure, furnace
Bulge or even explosion will occur for pipe；The raising of furnace tube temperature can also make itself to generate heat expansion phenomenon, cause to be cracked, damage
Boiler.
Currently, common scale treatment method has: method for dosing medicine, pickling, membrane separation process, electromagnetic method etc., all to some extent
There is influence treatment effect or be difficult to the problem of promoting.Method for dosing medicine: dedicated antisludging agent is added into water, thus it is possible to vary calcium,
Characteristic of the magnesium ion in conjunction with carbanion, to prevent scale from being precipitated, depositing.The more dirt of the antisludging agent of generation is easy
Pipeline blockage is caused, waste of manpower resource and time, treatment effeciency are low.Acid wash: with the method for hydrochloric acid or sulfuric acid cleaned scale,
It is mainly used for being worth lower industry heat and calculates equipment, such as chemical industry cooler, and for expensive industrial professional equipment, uses salt
Acid or sulfuric acid cleaned are undoubtedly a kind of destruction, should not use.Membrane separation process: nanofiltration membrane (NF) and reverse osmosis membrane (RO) can be with
Calcium, the magnesium, silicon ion in water are intercepted, to fundamentally reduce the hardness of water.This method effect is obvious and stablizes, after processing
Water it is applied widely, but have higher requirements to intake pressure, equipment investment, operating cost are all higher.Electromagnetic method: in water
In addition certain electric field or magnetic field change the characteristic of ion, thus when changing the speed and deposition of calcium carbonate (magnesium carbonate) deposition
Physical characteristic prevent the formation of hard water scale.Its main feature is that: equipment investment is few, easy for installation, and operating cost is low；But it imitates
Fruit is not sufficiently stable, ununified measurement standard.
People gradually recognize the necessity of softened water, and soft water material passes through the development and improvement of many years, and hard water is soft at present
The most commonly used is ion exchange resin for change.It utilizes the commutativity of resin, and calcium, magnesium, silicon ion in water are replaced, reduced in water
Calcium, magnesium, silicon ion content, to reduce the formation of scale.And resin has affinity, will not cause secondary pollution to water body.
In order to further increase scale removal resin material selection adsorption capacity and except silicon performance, reduce cost of manufacture, research and development are new
The production method that type removes the resin material of removing calcium and magnesium silicon is its key point.Therefore, it is proposed to which a kind of flocculant PAC production is gone
The preparation method of the resin material of removing calcium and magnesium silicon, contained aluminium and ferrous metal member in the flocculant for making full use of purity not high (PAC)
Element, and the oxide precipitation nano particle of two kinds of metals is embedded in cation exchange resin utilizes resin charge force and interior
Engaged column oxide nano particles and calcium, magnesium, the chemical bonding of silicon and positive resin Selective adsorption, in water body calcium,
Magnesium, silicon carry out efficient selective absorption.
Summary of the invention
