专利汇可以提供Incineration method for combustible industrial wastage and a fluidized bed furnace used therefor专利检索，专利查询，专利分析的服务。并且There are disclosed an incineration method and a fluidized bed furnace for use in the treatment of industrial waste, in which combustible industrial wastage pieces are carried under heating in the fluidized medium of cement clinker granules for incineration, while acid gases contained in a waste gas accruing from the incineration of the wastage are reacted with clinker granules to thereby fix acid gases in clinker granules, whereby acid gases may be removed from the aforesaid waste gas. According to the method and furnace of the invention, toxic acid gases produced during the incineration of the wastage may be removed effectively, without causing public nuisance or atmospheric pollution, while keeping a long run operation.，下面是Incineration method for combustible industrial wastage and a fluidized bed furnace used therefor专利的具体信息内容。

权利要求

1. A method for incinerating combustible industrial wastage, comprising the steps of: fluidizing the combustible industrial wastage with cement clinker granules serving as a fluidizing medium; heating the fluidized combustible industrial wastage and cement clinker granules sufficiently to incinerate the combustible industrIal wastage and thereby generate combustion waste gases from the combustible industrial wastage as it is incinerated, which combustible waste gases include acid gases; contacting the combustion waste gases thus generated by the incineration of the combustible industrial wastage, which combustion waste gases include acid gases, with the fluidized cement clinker granules sufficiently to react the acid gases with the cement clinker granules and thereby remove the acid gases from the combustion waste gas.

2. A method as defined in claim 1, wherein the cement clinker granules are provided with a composition before reaction, by weight percentage, of from 62 to 66% CaO, from 1 to 2% MgO, from 20 to 25% SiO2, from 4 to 6% A12O3, from 2 to 4% Fe2O3, and from 1 to 2% SO3.

3. A method as defined in claim 2, wherein the cement clinker granules are provided with a grain size distribution before reaction with a range of from 0.1 to 3mm in diameter.

4. A method as defined in claim 3, wherein said step of heating is carried out at a temperature between 800* C and 1,450* C.

5. A method as defined in claim 1, wherein the cement clinker granules are provided with a grain size distribution before reaction with a range of from 0.1 to 3mm in diameter.

6. A method as defined in claim 5, wherein said step of heating is carried out at a temperature between 800* C and 1,450* C.

7. A method as defined in claim 1, wherein said step of heating is carried out at a temperature between 800* C and 1,450* C.

8. A method as defined in claim 7, wherein the cement clinker granules are provided with a composition before reaction, by weight percentage, of from 62 to 66% CaO, from 1 to 2% MgO, from 20 to 25% SiO2, from 4 to 6% Al2O3, from 2 to 4% Fe2O3, and from 1 to 2% SO3.
