Dust deposition inhibitor for dust removal water system in steelworks

Abstract

The dust deposition inhibitor of the dedusting water system of the steelworks is an ideal water treatment agent that can be used for descaling, scale inhibition and dust suppression of the dedusting water system of the steelworks. It is a comprehensive multifunctional chemical descaling, antiscaling and dust inhibitor composed of materials such as polyphosphonate and organic polymer with descaling, antiscaling and dispersing properties as the main agent, and inorganic salts and various additives as auxiliary agents. . Descaling, anti-scaling, dust suppression, good effect. No hydrogen embrittlement, no corrosion, no poison, no smell, no pollution. The dust deposition inhibitor product of the dedusting water system of a steel plant of the present invention can be used in the dedusting water system to achieve: the scale inhibition rate is 100%. The descaling rate is 99.5%. The ring erosion rate is 99.6%. When the dedusting water system through scale removal, scale inhibition and dust suppression is running without scale, there is no need to stop production for cleaning and maintenance, which reduces huge economic losses and achieves greater economic benefits.

Description

Technical field [0001] The invention is a multifunctional chemical water treatment agent for scale removal, scale inhibition and dust suppression provided by the deposition and scaling of dust, calcium, magnesium and other substances in the dust removal water system of a steelmaking plant. [0002] After long-term operation of the equipment dust removal water system in steel mills and the different effects of water supply treatment, various impurities will inevitably be produced in the system. During the high temperature heating process of the equipment, deposits will form on the inner surface of the equipment to form dirt. C a 2+ , M g 2+ The salt of the plasma precipitates and deposits on the metal surface in the form of crystals at high temperature, forming dense and hard scale. Therefore, when the equipment accumulates dust, sediment, and hard scale to a certain amount, the thermal efficiency will decrease, and the thermal efficiency will easily cause the metal to overheat at ...

AI Technical Summary

Problems solved by technology

[0003] Now there are many kinds of water treatment agent technology, such as: ion exchange resin softening water method of physical method, scale inhibitor and pickling agent, etc., all have certain disadvantages, such as: using resin method, only scale inhibition, not removal Dirt, no corrosion protection, large investment, complicated management

The method of scale inhibition can only inhibit scale, but not remove scale, relatively simple

The pickling method is very corrosive to the equipment, easily damages the equipment, causes great economic losses, and reduces the life of the equipment

In addition, the above method is relatively expensive
