Method for manufacturing recycled building material cement of the same quality and its finished products. [Previous technology] According to the current, the garbage generated by the daily life of citizens can be divided into landfill method and incineration method. Among them, the burial method must have a relatively large burial area location. After the garbage is dumped directly and sequentially, it is buried in a layer of soil, which is repeated. However, this method requires a large burial space, and There is a little carelessness during the landfill process, which may cause secondary environmental pollution and other pollution problems, and the possibility and danger of fire caused by the biogas produced by the landfill. The most serious problem is that it can be used as a landfill site. It is not easy to obtain; therefore, the government also vigorously promotes the incineration of waste. On the one hand, it is reduced by incineration. The residual bottom ash generated after incineration is about 20 to 30% of the amount of incinerated waste, and The amount of fly ash is about 10% of the amount of bottom ash. It can indeed achieve an effective reduction effect; however, the final treatment method of the bottom ash and fly ash produced by these incinerations must still be disposed of in a landfill manner, and to prevent Light-weight ashes such as bottom ash and fly ash cause environmental air pollution, and further 5 must be cured by cement before being buried, so the same It is necessary to face the problem that the landfill is not easy to fight with the residents. The residual bottom ash and fly ash after incineration still contain contaminating and toxic substances such as dioxin, harmful heavy metals and polychlorinated biphenyls. When it is buried, it still cannot be decomposed and buried in the ground, which causes the problem of secondary environmental pollution. Therefore, how can the bottom ash and fly ash generated by these incineration be effectively used, and various toxic or harmful substances can be removed?

The kiln firing equipment is best used in a rotary kiln. According to the actual requirements, it is necessary to choose a larger firing zone or a calcining zone. Dazhi rotary kiln is used; it has different temperature zones in the rotary kiln, including 100 ° C ~ 600 °. Preheating zone. When the cement raw material enters this preheating zone, an endothermic reaction occurs, and the water begins to evaporate and release the crystallization water in the cement raw material. Then it enters the calcination zone at 900 ° C ~ 1000 ° C. After different temperatures, The cement raw meal begins to exothermic, at this time, the non-crystalline cement raw meal begins to change into a crystalline form. At the same time, the endothermic reaction of limestone in the cement raw meal releases carbon dioxide into calcium oxide; finally it enters 1100 ° c ~ 1400 ° c. In the compounding zone, the cement raw material exothermicly reacts at south temperature to complete the reaction of the cement to become a nearly liquid cement clinker. The chemical changes are: CaC03 and MgC03 are decomposed;% 20 and M are volatile; FeO is oxidized to FeO3; CaO, MsO, AhO3, and Fe203 are combined to produce salts such as silicic acid and aluminate. The organic salt, dioxin and 15 200426130 heavy metals contained in the cement raw material will evaporate and decompose into molten fly ash with fine particles at high temperature, which can be combined with desalination technology for degassing project and environmental protection recycling equipment. Detoxification technology and demetallization technology standard 'remove dioxin and harmful heavy metals from cement raw materials. The removal of the organic salts contained in the cement raw material is because the raw raw materials used in the cement raw material are bottom ash, fly ash generated from waste incineration, and sludge generated from sewage treatment. In order to achieve the gaseous ion content in the cement clinker which is less than 0.1% of the mass of the cement, the excess gaseous ion must be removed; the removal of the organic salts, It is mainly used in combination with desalination technology for degassing. In a specific embodiment method, it is used in the homogeneous process of cement raw materials to add an appropriate amount of sodium compounds, such as one of the groups such as sodium carbonate; through the satin firing process, The large amount of gas ions (CI-) and sodium ions (Na) contained in the raw material are combined to form sodium gasification (as 1), which is volatilized in the gas, and then discharged with the gas, so that the gas content of the cement in the finished product can be Meet the requirements of 0.1% cement quality regulations. The recycled raw materials in the cement raw meal are the bottom ash, fly ash and sewage sludge generated from the waste incineration, and relatively harmful heavy metals such as extract, plutonium, Pb, As must be removed. The The removal method is carried out in combination with demetalization technology and environmentally friendly recycling equipment, that is, the thermal decomposition occurs in the high-temperature calcination of the compound zone in which the harmful heavy metals Hg, Cd, Pb, and As contained in the aforementioned cement raw material are equal to the calcination process. The metal ions evaporate and volatilize in the gas and combine with HCI, and are concentrated in the metal salt of the refining fly ash into fine particles. With the gas discharge, the aforementioned environmental protection recovery equipment is used, that is, the coarse dust is collected by the cyclone dust collector to recover the coarse particles. And sent to the kiln for calcination again. As for 26 200426130, the fine particles of salt containing indifferent heavy metals are converted to fly ash, and then completely captured by the bag-type dust-collecting equipment, the removal of the heavy metals in the cement raw meal can be completed; The produced concentrated heavy metal salt is micro-tested, which can be further improved by reading and regenerating heavy metals. In the same way, the regeneration of cement fortunes and PCDDs and PCDFs dioxins contained in toxic substances stored in money must also be removed, and the new synthesis of dioxin by synthesis of dioxin should be prevented to synthesize the more toxic dioxin. This poison decomposition technology is based on the high-temperature calcination of the compounding zone of the described calcination process. Dioxins undergo a desalination reaction, which is replaced by gas and hydrogen, and completely decomposed into ^ ~ qin ... and ^ "and volatilized in gas. The suitable temperature for the new synthesis of Dioxin (DoNoVo Synthesis) is about 30 (TC). Therefore, in the gas emission, a rapid cooling tower is connected to rapidly cool the high-temperature exhaust gas to the temperature of the new synthesis reaction of Dioxin (about 3,000). c) The following, for example, 20 (rc), so that dioxin can be completely decomposed and eliminated. The emitted gas is then removed by the denitration equipment to remove NOx and SOx to reach the gas emission standard and discharged into the atmosphere through smoke. Example: The raw materials such as bottom ash, fly ash, sewage sludge generated from waste incineration, and stone® limestone are mixed in a pre-process to form cement raw materials that replace the raw materials of the ore. The proportion coefficient and limit of chemical composition of Tran cement standard allow accurate calculation and deployment, such as the proportion coefficient of cement composition: hydraulic rate (Η · M ·) = CaO (%) —S〇2 (%) xO · 7 / Si〇2 (%) + Al2〇3 (%) + F62O3 (%) 17 200426130 Silicon Oxide Rate (SM ·) = Si〇2 (%) / Al2〇3 (%) + Fe2〇3 (%) Iron Rate (Ι · Μ ·) = Al2〇3 (%) / Fe2〇3 (%) Activity coefficient (A · I.) = Si〇2 (%) / Al2〇3 (%) Hydraulic coefficient (Η · I · ) = Si〇2 (%) + Al2〇3 (%) / CaO (%) Lime ratio (LR ·) = CaO (%) / Si〇2 (%) — AI2O3 (%) Iron bauxite ratio (IAR · ) = Fe2〇3 (%) / Al2〇3 (%) Cement composition ratio coefficient and limit: · Hydraulic set rate (Η · Μ ·) Hydraulic Modulus 1 · 7 ~ 2 · 4 Shixi oxygen rate (S · Μ · ) Silica Modulus 1 · 8 ~ 3 · 2 Ferrite rate (I · M ·) Iron Modulus 0 · 7 ~ 2 · 0 Activity coefficient (Α · Ι ·) Activity Index 2 · 5 ~ 6 · 0 Hydraulic coefficient (Η · Ι ·) Hydraulic Index 0.42 ~ 0.48 Lime Ratio (LR ·) Lime Ratio < 2.85 Iron bauxite ratio (Ι · A · R ·) Iron Oxide / Alumina 1.4 · 0.5 ~ 0.5 f After the aforementioned chemical composition distribution ratio is determined, the volatile components contained in the raw materials such as fly ash, carbon dioxide in limestone and water in sludge bottom ash are released during the forging process, so the weight loss is 4 each read secret, by reaction of burning decomposition calculation Cac〇 = ··
