Said method includes the following steps: mixing brown coal and coking coal according to a certain mixing ratio, pulverizing them to obtain coal powder; adding coal tar and water base emulsifying agent to make them into coal paste; hydraulic strip-extruding to obtain strip granules, drying and charring in charring furnace, placing the above-mentioned material into activating furnace to make activation to obtain activated material, making natural oxidation so as to obtain the invented active coke.
Description
Technical field:
The present invention relates to a kind of desulphurization denitration activated coke and production method, especially directly make and energy dust-removing active coke and production technique thereof of brown coal.
Background technology:
The Activated Carbon Production method that is used for flue gas desulfurization and denitrification at present is more, how the gac of semicoke is done chemical treatment, to increase the ability of surface devulcanization denitration.Though the gac of aforementioned production method can desulphurization denitration, but still exist that specific surface area is little, intensity is low, mesopore is undeveloped and shortcoming such as desulfurization off sulfide effect difference, because also difference of the different used starting material of method respectively has relative merits.Adopt brown coal to add tackiness agent as German BF company, be used for heat power plant's dry desulfurization device through charing, can only desulfurization, can not remove oxynitride and dust; Sino-Chinese Shipping Association BJ Office forms coke powder with coal through low-temperature pyrolysis, mixes under heating condition with tackiness agent behind the abrasive dust, is shaped after destructive distillation, activation form gac, and technology is complicated; The disclosed preparation active carbon method of CN1202004C, in redox processes with multiple gas such as ammonias, hydrogen, ethene, i.e. cost height, technology is complicated again; The disclosed activated coke preparation method of CN1120746C, soak time is 5-6 hour, prepared gac intensity is lower; Disclosed a kind of desulfurization catalyst of flue gas of CN1089034C and application method thereof have only solved desulphurization problem; The preparation method of the disclosed smoke gas treatment activated coke of CN1806910A will use KOH, KCl, NaOH, urea etc., and at normal temperatures pitch be ground to form the 180-400 order, and technical difficulty is higher, is difficult for realizing; Disclosed a kind of while desulphurization denitration gac of CN1212887C and application method thereof, complex process cost height; The disclosed a kind of preparation process of active carbon of CN1491886A will be reduced processing condition complexity, cost height under ammonia, hydrogen, methylamine, ethene or acetylene condition; The disclosed production desulphurization denitration of CN1200876C process of active carbon, mix the back abrasive dust with coking coal with bituminous coal, mix with coal tar again, be shaped to strip particle by liquefaction, make gac through charing, activation, oxidation three segment process processes, gac with this method preparation also exists cost higher, the heavy less deficiency of heap.
Summary of the invention:
Purpose of the present invention just is at above-mentioned the deficiencies in the prior art, and a kind of intensity height, mesopore prosperity are provided, and not only desulfurization off sulfide effect is good, and can dust separating desulfur denitrate dust collecting active coke of while and production method thereof.
Another object of the present invention is also to can be used as flue gas ash removal with the activated coke that this method prepares in desulphurization denitration to use.
The objective of the invention is to realize in the following manner:
Comprise following order and step:
A, at first brown coal and coking coal are broken into the coal cinder of particle diameter less than 15mm respectively, by weight percentage the 70-85% brown coal are mixed with the 15-30% coking coal then, be ground into the following coal dust of 300 orders again;
B, get 70-82% coal dust, 15-25% coal tar and the agent of 3-5% water-based emulsion by weight percentage and send into to stir in the kneader and make coal cream;
Strip particle is made in c, the extrusion molding under 25-30MPa pressure of coal cream;
D, strip particle is sent in the 400-700 ℃ of charring furnace oven dry, charing 1.5-3 hour again, once finished oven dry, carbonization process;
E, the strip particle after the charing is sent into temperature is that 800-1000 ℃, pressure are 50-150Pa, have in the activation furnace of oxidation atmosphere, feed steam activation and made activated material in 1.5-2.5 hour, activated material entered temperature-fall period through 1-2 hour, and natural oxidation forms has the activated coke of enriching the surface functional group structure.
Tensio-active agent in the said water-based emulsion agent of step b is the cats product nonionogenic tenside, or amphoterics, and the part by weight of tensio-active agent in the water-based emulsion agent is 1-10%.
In desulphurization denitration, be applied to flue gas ash removal.
Beneficial effect: evidence, with brown coal as the main raw material of making activated coke, relative low price not only, the activated coke performance of made is removed has the intensity height, outside the characteristics that mesopore is flourishing and desulfurization off sulfide effect is good, also can in desulphurization denitration, be applied to flue gas ash removal.
