Abstract
A moulded coal (coke) fuel with combustible waterproof, sulfur fixation functions is made up by using coal as raw material and adding compound binder composed of lime and black liquor of paper mill. Its water proof ability can make coal briquette not disintegrate in water and its sulfur fixation ability can up to higher than 40-80%. Its cost is lower than that of raw coal.
Description
The present invention relates to a kind of moulded coal (Jiao) fuel.The compound binding agent that this moulded coal (Jiao) fuel has mainly used lime and alkali paper-making black liquor to form.
Using lime is that smalls, breeze that fertilizer industry produces natural carbon piece, coke in process of production are processed into moulded coal and make full use of into factory's resource to reach, a traditional method of reducing expenses as briquette binder.But lime adding amount is big.And owing to need the charcoal acidification, therefore, complex process, cost height.Go into easily efflorescence behind the stove.Use the disclosed black liquor of handling through modification of black liquid or technology to make briquette binder, waterproof ability all can not reach the suitability for industrialized production requirement.
Use lime that alkali paper-making black liquor is carried out the modification processing and then can realize having complementary advantages, make moulded coal have waterproof, solid sulphur, inflammable function simultaneously.Institute's production of shaped coal can the wet bulb entry after a couple of days do not loose.Dry or fire do after, waterproof ability is constant.This technology has been finished the suitability for industrialized production test.Example is as follows:
Example 1: hard coal D-type boilerD moulded coal.Particle diameter is less than smalls or the coal slime of 5mm, the Ca of outer coal raw material weight 10% (OH)
2With 10% black liquid.With roller briquetting machine or garden dish tablets press moulding, use dry back.Can realize energy-conservation 20%.Sulfur-fixing rate is: during roller press briquetting 40%, during the dish balling-up of garden greater than 60%.No matter making, moulding how all has the waterproof ability that the wet bulb entry is not loose.
Example 2: bituminous coal D-type boilerD moulded coal.Carried out multiple test, be summarized as follows: coal raw materials can be 100% bituminous coal smalls or coal slime, can also add 50～80% hard coal smalls or coal slime according to the bituminous coal composition as one feels fit.Add Ca (OH)
2The same with the black liquor amount.Forming method is the same.Moulded coal function and effect are the same.
Example 3: slag can be made the industrial shaping coal of cement clinker.Coal raw materials is 50% bituminous coal, 50% hard coal, and adding CaO is 20%, black liquor 10%, garden dish comminution granulation is made.Moulded coal function and effect are the same.Its slag can directly be made cement clinker and use.
Example 4: gas furnace gas-making type coal (Jiao).Smalls or breeze 75%, bituminous coal mud 20%, wilkinite 5% adds CaO5%, black liquid 15%, roller press briquetting.After institute's production of shaped coal drying, cold strength is greater than the 60Kg/ ball, and hot strength is greater than the 40Kg/ ball, thermostability greater than 80%, 1100 ℃ to CO
2Active in 85%, entry is soaked and was not brokenly split in 24 hours, and ash fusion point is not less than the ash fusion point of feed coal.
Example 5: coal briquette for civillan use.Hard coal smalls or coal slime 80%, loess 20% adds slaked lime powder 5%, adjusts it in right amount with black liquid and does wet degree with convenient degree of being shaped to.Institute's production of shaped coal can outdoor storage, and solid sulphur.
Example 6: boiling boiler moulded coal.Sulphur content is 4.01% high sulphur coal fine coal; add 3%CaO; 3% clay; high sulphur coal fine coal with black liquid stoste adds 10%CaO directly into usefulness on another garden dish tablets press after causing particle diameter to be the following bead of 6mm on the dish tablets press of garden still uses black liquid stoste compound last layer shell on protocorm.Use after the balling-up drying.Efficiency of combustion 95%, flyash reduces 90%, sulfur-fixing rate 81%.Slag can directly be made haydite and use.
