| <P>PROBLEM TO BE SOLVED: To provide a method of producing cement by which water-soluble mercury contained in a cement raw material such as coal ash, garbage incineration ash and/or sewage sludge incineration ash is removed and the removed mercury is simply processed. <P>SOLUTION: In the method of the cement, the water-soluble mercury is removed by washing the cement raw material such as coal ash, garbage incineration ash and/or sewage sludge incineration ash with water. By the producing method, the mercury in the cement kiln is sufficiently reduced with a simple process of washing with water. <P>COPYRIGHT: (C)2008,JPO&INPIT | ||||||

| PROBLEM TO BE SOLVED: To provide a concrete product which is good in strength revelation in spite of using more refuse originating material even in the case of being subjected to the steam aging. SOLUTION: The concrete product is manufactured by forming a mixture of a hydraulic composition, composed of a crushed material of a fired matter manufactured from at least ≥ one between refuse incinerated ash and sludge incinerated ash as a raw material, an aggregate, a part of or whole of which is made by refuse originating material, and a composition containing water, then hardened by steam aging.

| PROBLEM TO BE SOLVED: To solve the problem in the conventional art that dioxin is formed in incineration treatment of waste, and the dioxin is contained, as a natural result, in the incineration ash of the waste, if the ash is dumped as it is in a disposal site, the dioxin remains toxic, further if the dioxin is solidified with cement at normal temperature, hazard of the dioxin remains exposed. SOLUTION: In the treatment of general and industrial wastes, and treatment of incineration ash and fly ash, a system of a direct melting furnace is employed. The furnace comprises a coke bed, which is very effective for restriction of dioxin formation. In this furnace, a reduction reaction occurs at a temperature of at least 1,000 deg.C, a sufficient temperature for conducting a thermal decomposition of dioxin. Slag melted at high temperature is discharged to the outside of the furnace and cooled, even if dioxin recombination is generated in the cooling time, elution of harmful mater is hindered by the sticking action of the slag. | ||||||

| PROBLEM TO BE SOLVED: To provide a treatment process for converting waste such as municipal refuse incineration ash or sewage sludge incineration ash, into a treated material which contains substantially no sulfate ions and has a drastically reduced lead content and is suitable as a cement raw material by subjecting such waste to sulfuric acid leaching to elute and separate copper and zinc from the waste, further subjecting the sulfuric acid-leaching residue to alkali leaching to elute and separate lead from the residue and converting gypsum in the reside into calcium hydroxide. SOLUTION: This treatment process comprises: adding sulfuric acid to waste such as municipal refuse incineration ash or sewage sludge incineration ash or solid matter in a slurry of such waste thereby subjecting the waste to sulfuric acid leaching in a ≤400 g/l solid/liquid ratio and at a pH of ≤4, to decompose and elute copper and zinc, to solidify lead and calcium as lead sulfate and gypsum, respectively, so as to allow them to remain in the residue and to perform liquid-solid separation of the leachate and the residue from each other; and adding an alkali to the surface acid-leaching residue so as to form a slurry having a ≤200 g/l solid/ liquid ratio and strong alkalinity of a pH of ≥13.5, to leach most of lead, to convert gypsum into calcium hydroxide, to perform solid-liquid separation of the leachate and the alkali- leaching residue from each other and to remove sulfate ion. Thus, the recovered solid matter (alkali-leaching residue) containing substantially no lead and almost no sulfate ion is appropriately used as a cement raw material. Further preferably, the waste is subjected to water washing treatment in a 300 g/l solid/liquid ratio beforehand to remove water-soluble chlorine compounds. COPYRIGHT: (C)2000,JPO | ||||||

| PROBLEM TO BE SOLVED: To recover phosphorus as high-purity phosphoric acid, to suppress the reaction to form calcium sulfate and not to deteriorate cement when used as a cement material by applying solid-liq. separation to a slurry obtained by adding sulfuric acid to sludge incineration ash, recovering a phosphoric acid soln. from the separated liq., adding an alkali soln. to the separated solid and using the solid residue separated from liq. as the cement material. SOLUTION: Any sludge incineration ash contg. a phosphorus component can be used, and the incineration ash of sewage sludge, river sludge or silt is normally used. The incineration ash contg. a large amt. of an alkaline-earth metal component such as calcium and so on is preferably used. Phosphorus is leached out by sulfuric acid in an ordinary temp. range of 0-40 deg.C. The normality of the sulfuric acid soln. is preferably >=1 to increase the elution efficiency, and 1 N sulfuric acid is preferably used by 3300 ml for 100 g of the incineration ash. Sodium hydroxide is used in the alkali soln., and >=500 ml of the soln. is added to 100 g of the solid residue after the sulfuric acid is added. | ||||||

| PROBLEM TO BE SOLVED: To provide a method for pyrolyzing dioxin worried on the employment of incinerated ash in the production of an ecological cement, and to provide a device for pyrolyzing the dioxin. SOLUTION: This method for pyrolyzing dioxin comprises collecting kiln dust containing the non-pyrolyzed dioxin, treating the collected kiln dust 14 with an acid to precipitate the dioxin together with the lead product, heating the precipitates at a higher temperature than the boiling point of the dioxin, guiding the evaporated dioxin-containing gas 20 into a rotary kiln 3 for calcining a cement, and subsequently pyrolyzing the guided dioxin with heat on the calcination of the cement. | ||||||

| PROBLEM TO BE SOLVED: To surely and inexpensively make dioxin non-polluting by feeding refuse incineration ash contg. the dioxin into a cement kiln for firing cement clinker from cement raw materials and pyrolyzing the dioxin in the refuse incineration ash by the firing heat at firing the clinker. SOLUTION: The cement raw materials are calcined during the flow down in the respective cyclones 2a of a preheater 2 and are thereafter fed to the kiln tail section 4a of the cement kiln 4 where the cement clinker is fired by burner heating. At this time, the refuse incineration ash contg. the dioxin stored in a storage tank 9 is fed into the kiln tail section 4a by a truck 8 from a refuse incineration furnace 5 and a dust collector 6. Burner heating is executed at a temp. exceeding the pyrolysis temp. of the dioxin in the cement kiln 4 and is rotated at a low speed in a circumferential direction. As a result, the cement clinker is fired and simultaneously the dioxin included in the fed refuse incineration ash is well pyrolyzed and made non-polluting. | ||||||

| PROBLEM TO BE SOLVED: To enable the stable operation of a kiln possible by rapidly cooling the waste gases at the tail at the kiln, thereby eliminating coating troubles and suppressing the reformation of dioxin and to stable produce cement and cement based solidifying material by efficiency treating waste gas dust and effectively utilizing this gas in the production of the cement and cement based solidifying material by firing the chlorine-contg. raw materials, such as incineration ashes of municipal waste, in the kiln. SOLUTION: The waste gases at the kiln end are cooled with air or water to lower the waste gas temp. down to ≤400°C, more preferably ≤300°C. Further, calcium carbonate, dolomite, quicklime or slaked lime, etc., are blown to the waste gases to rapidly cool the gases. The apparatus for production is illustrated in the Fig. The compounded raw materials contg. cement raw materials, etc., are molded to about 5 to 50mm and the moldings are supplied, after drying, into the kiln 1 from a housing 3. The moldings are cooled in a clinker cooler 6 after firing. The waste gases are introduced to a waste gas duct 3, a classifying means 4, a dust collector 5 and a fan device 7. A rapid cooling means 8 is disposed in the lower part 3b of a discharge duct 3. COPYRIGHT: (C)1997,JPO | ||||||
