专利汇可以提供Waste disposal method and system专利检索，专利查询，专利分析的服务。并且In a method for the combined processing for disposal of industrial, problem waste, of problem free waste and of slush as resulting from sewage treatment, wherein the problem waste is pyrolytically carbonized on a continuous, revolving basis, and wherein the resulting coke is mixed with heated acidized slush, filtered and drained. The gas developed during carbonization is washed and used as heating agent; the mixture is then mixed with problem free waste to obtain a coke-slush waste mixture and the said latter mixture is burnt.，下面是Waste disposal method and system专利的具体信息内容。

权利要求

1. IN A METHOD FOR THE COMBINED PROCESSING FOR DISPOSAL OF INDUSTRIAL, PROBLEM WASTE, OF PROBLEM FREE WASTE AND OF SLUSH AS RESULTING FROM SEWAGE TREATMENT, WHEREIN THE PROBLEM WASTE IS PYROLYTICALLY CARBONIZED, AND WHEREIN THE RESULTING COKE IS MIXED WITH THE SLUSH, FILTERED AND DRAINED, THE IMPROVEMENT COMPRISING: PROVIDING A CONTINUOUS CARBONIZING OF THE PROBLEM WASTE BY MEANS OF REVOLVING THE PROBLEM WASTE WHILE HEATING IT UNDER EXCLUSION OF AIR TO OBTAIN COKE IN A PROGRESSING CARBONIZATION OF THE REVOLVING PROBLEM WASTE; HEATING THE SLUSH TO A TEMPERATURE OF ABOUT 60* TO 80* CENTIGRADE; MIXING THE COKE AS PROVIDED BY THE CARBONIZATION WITH THE HEATED SLUSH TO OBTAIN A COKE-SLUSH MIXTURE; MIXING THE MIXTURE WITH THE PROBLEM FREE WASTE TO OBTAIN A COKE-SLUSH WASTE MIXTURE; AND BURNING THE SAID LATTER MIXTURE.

2. Method as in claim 1, including adding acid to the slush prior to heating and neutralizing the heated slush by means of lime.

3. Method as in claim 1, wherein the coke-slush mixture is drained to a dry product content of at least 30 percent.

4. Method as in claim 1, wherein the carbonizing step uses a revolving oven rotating on a horizontal or slightly inclined axis.

5. Method as in claim 4, using an acid-proof oven with closed front ends respectively, for charging the rotating oven with unfragmentized problem waste at one front end and dischraging coke coke at the opposite end.

6. Method as in claim 4, wherein the oven has enclosed duct means, and conducting fuel gas from the oven through said duct means.

7. Method as in claim 6, and including, extracting gas from the carbonizing process, cleaning the extracted gas; and burning the gas as cleaned is used for sustaining the carbonizing.

8. In a system for treating problem waste, sewage plant slush and problem free waste, comprising: means for carbonizing the problem waste under continuous rotation; means for heating the slush; means for mixing the carbonized problem waste and the heated slush; means connected to the means for mixing, for draining the mixed carbonized problem waste and heated slush; means connected to the means for draining, for mixing the drained carbonized problem waste and slush mixture with problem free waste; and means for burning the latter mixture.

9. In a system as in claim 8, wherein the means for carbonizing includes a carbonizing oven chamber rotating on an approximately horizontal axis, lifted at one end, the problem waste being charged to the oven from that one end and coke being discharged from the opposite end.

10. In a system as in claim 9, wherein the oven chamber is lined by a lining, the lining being traversed by heating ducts.

11. In a system as in claim 8, including means for acidizing the slush prior to heating, and means for neutralizing the treated slush.
