Abstract
The invention relates to a practical environment-friendly type water-quenched coke strength reinforcing agent. The invention belongs to the technical field of coking. The enhanced agent comprises a well mixed mixture of hexamethylenetetramine, imidazole, a boron source, a surfactant source, ammonia water, and water. The materials are well mixed according to weight percentages. The agent is dissolved in coke-quenching water, such that a dilute water solution with a concentration of 0.01-1% is prepared, and the water solution can be used for quenching coke. When the coke quenching water solution with the added practical environment-friendly type water-quenched coke strength reinforcing agent is used for quenching coke, gas bubbles generated by the surfactant source assist in increasing the specific surface area of the coke, such that dust can be effectively absorbed, reactivity of the coke can be reduced, strength of the coke after reaction can be improved, water content of the coke can be reduced, and the discharging amount of harmful vapor can be greatly reduced.
Description
Technical field
The present invention relates to the practical formulation of a kind of environment-friendly type water quenching coke strenth toughener, belong to the coking technology field.
Background technology
The extinguishing technique that coke production is follow-up requires to make red-hot coke fast cooling, is convenient to transportation and storage.The quenching technology is divided into two kinds of dry method and wet methods, and dry coke quenching has the effect that improves coke quality, environmental protection, recovery heat energy, but because investment and working cost are high, also is difficult to popularization in the short period of time.Wet putting out is the quenching technology that generally adopts at present, the advantage of wet quenching is that investment and process cost are low, management is simple, shortcoming is to reduce coke strenth and moisture height and unstable after the quenching, red-hot coke sprays at water and produces the water vapour that is entrained with a large amount of dust, phenol, sulfide etc. in the quick process of cooling simultaneously, causes environmental pollution and thermal pollution.Along with the maximization of blast furnace and the raising of combustion intensity, the specification of quality of blast furnace STRENGTH ON COKE is more and more higher, and Coking Coal Quality has year by year downtrending, the coal of coking coal, quality occur than great fluctuation process, the coke quality of producing is difficult to satisfy the large blast furnace strengthening smelting, further improves the requirement of coal ejection ratio, and the fewer and feweri and coke quality of high-quality caking coal requires more and more higher contradiction day by day serious.And the global pay attention to day by day to environment protection so that coal chemical enterprise faces immense pressure, has jeopardized the Sustainable development of coking and metallurgy industry.At present wet put out to have in the technique still adopt traditional water quenching, have above-mentioned problem demanding prompt solution; The passivator technology that adopts is arranged, and postreaction strength of coke is improved, but environmental influence is not improved, and especially the blast furnace effect is not obvious, and coke ratio does not obviously reduce; Useful air film coke quenching agent technology, environmental influence is improved, coke quality is improved, but exists coke cold and hot index increase rate less, and the blast furnace effect is unstable, the problem that application cost is high.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, provide a kind of environment-friendly type water quenching coke strenth toughener practical formulation, this practicality formulation comprises: the mixture that hexa-methylene four ammoniums, imidazoles, boron source, surfactant source, ammoniacal liquor, water mix by weight percentage.This formulation is dissolved in to be hybridly prepared into concentration in the coke quenching water be that the dilute aqueous soln of 0.01-1% gets final product quenching.When adding the coke quenching water solution quenching of the practical agent of a kind of environment-friendly type water quenching coke strenth toughener, the bubble that surfactant source produces, can increase the coke ratio surface-area, effectively adsorb dust, reduce the reactivity of coke, improve postreaction strength of coke, reduce the coke water ratio, decrease is harmful to the discharge of steam amount.
The present invention realizes with following technical scheme: the practical formulation of a kind of environment-friendly type water quenching coke strenth toughener, it is characterized in that: this practicality formulation comprises: the mixture that hexa-methylene four ammonium 1-10%, imidazoles 0.1-1%, boron source 30-60%, surfactant source 10-40%, ammoniacal liquor 0.5-2%, water 10-20% mix by weight percentage.
The practical formulation of described a kind of environment-friendly type water quenching coke strenth toughener, it is characterized in that: described surfactant source comprises: Witco 1298 Soft Acid and sodium salt, cetyl trimethylammonium bromide, sodium lauryl sulphate; Described boron source comprises: boric acid, boron cash, borax; The raw material of the practical formulation of environment-friendly type water quenching coke strenth toughener is optional one in above-mentioned surfactant source, boron source.
Preferably, the practical formulation of environment-friendly type water quenching coke strenth toughener is made of by weight percentage hexa-methylene four ammonium 5-10%, imidazoles 0.1-0.5%, boron source 30-45%, surfactant source 10-30%, ammoniacal liquor 0.5-2%, water 10-20%.
The using method of the practical formulation of environment-friendly type water quenching coke strenth toughener is, this product is dissolved in to be hybridly prepared into concentration in the coke quenching water be that the dilute aqueous soln of 0.01-1% gets final product quenching.When adding the coke quenching water solution quenching of the practical formulation of a kind of environment-friendly type water quenching coke strenth toughener, the bubble of surfactant source generation can increase the coke ratio surface-area on the one hand, effectively adsorbs dust, reduces the quantity discharged of harmful steam; Boron source in the coke quenching water solution is formed and is filled the boronation film that adds the coke surface duct by the coke surface rapid permeability on the other hand, strengthens coke surface intensity.Thereby the environmental pollution that the decrease coke wet quenching causes and thermal pollution, the post-reaction strength of Effective Raise coke satisfies the requirement of modern blast furnace and strengthening smelting Coke Quality.
Effect of the present invention: use the quenching of practical agent coke quenching water solution, coke reactivity reduces 4-7%; Postreaction strength of coke improves 5-8%; Dust discharge amount reduces more than 95%; The discharge of steam amount obviously reduces; The coke water ratio reduces.Realized the reactivity of remarkable reduction coke, improved postreaction strength of coke, reduced the coke water ratio, decrease is harmful to the discharge of steam amount, has realized satisfying the requirement of modern blast furnace strengthening smelting Coke Quality and the purpose of energy-saving and emission-reduction.
