Description
Technical field
The present invention relates to water treatment agent field, a kind of corrosion inhibiting and descaling agent being applicable to low-pressure boiler equipment.
Background technology
Recirculated cooling water is to use water sport in water for industrial use, in the industries such as petrochemical industry, electric power, iron and steel, metallurgy, circulation
The consumption of cooling water accounts for the 50-90% of enterprise water use total amount.Owing to there being different salinity in former water, recirculated cooling water is concentrated to
Certain multiple must discharge certain dense water, and supplementary new water makes the salinity in cooling water, pH value, organic concentration, suspension
Thing content controls a rational allowed band, and water resources consumption is the biggest with the quantity of sewage discharge.Due to China's water
Resource critical shortage, protection environmental demand and regulation increasingly stringent.Therefore, recirculated cooling water design is considered as not affecting technique
Use water-saving and environmental protection new technique under condition as far as possible.Recirculated cooling water refers to be changed by heat exchanger heat-shift or direct contact
After hot mode comes exchange media heat cooled tower cold water, recycle, with saving water resource.
Circulating water cooling treatment is to ensure that the equipment such as cooling tower, cold water board is in optimal running status, circulates cold
But water processes and must effectively control microorganism species, the generation of suppression incrustation scale, the corrosion of prevention pipe-line equipment, and fouling can affect
Heat exchange efficiency, source of consuming energy more, affect technological operation, corrosion can reduce service life of equipment, and there is potential safety hazard.Circulating cooling
The process of water can be attributed to following four aspect: 1. removing oil removal: set up other filter device, other filter flow is generally recirculated water
The 1～5% of amount, filter and remove suspended substances matter.2. control fouling；Soften desalination or add antisludging agent.3. control corrosion rate；Add resistance
Dirt agent, makes metal surface form thin film and is covered by metal, thus completely cut off with corrosive medium, prevent metal erosion.4.
Control microorganism: add biocide.
Large, medium and small boiler stops fouling and corrosion, chemical treatment method in useable stove, adds anticorrosion in boiler feed water
Antisludging agent, reduces boiler water hardness demineralized water, reduces fouling and corrosion, and this method is simple and practical, receives praises from customers.And delay
Erosion antisludging agent is of a great variety, it is common that compounding of some structure specilization compounds, and will be according to metal surface situation, corrosive medium
The factors such as composition and ruuning situation carry out kind selection.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of corrosion inhibiting and descaling agent being applicable to low-pressure boiler equipment, reach
Reduce the purpose in the service life of energy consumption, extension device.
To achieve these goals, present invention employs techniques below scheme:
A kind of corrosion inhibiting and descaling agent being applicable to low-pressure boiler equipment, raw material and weight portion thereof are as follows: sodium xylene sulfonate 25
～30 parts, poly-epoxy succinic acid 5～10 parts, vanadic acid sodium 3～8 parts, matrine 0.5～0.8 part, Tween 80 5～10 parts and benzene
Methanol 20～25 parts.
Compared with prior art, the beneficial effect that the present invention possesses:
Control industrial circulating cooling water system fouling and corrosion, effectively suppress growth of microorganism, it is ensured that the heat exchange effect of equipment
Rate and service life, not only can improve the recycling rate of waterused of water, saving water resource, and can greatly improve recirculated cooling water
Integral status.
