Claims (9)

1. the process for the unification of calcined cement production as Lumps with solid waste combustion, which include: (a) the burning of such wastes in a rotary kiln to generate flue gases and dross (b) transfer of such flue gases to the combustion chamber. Second (c) the heat of the flue gas to at least 1050 ํ C for the presence of oxygen in the second combustion chamber. The retention time of such flue gases in the combustion chamber Such a second burn will be long enough for the flue gas to be completely burned completely. (D) the transfer of the very hot flue gas to the cement pre-calciner system, where the pre-calciner system consists of two Pre-calciner containing raw powder cement (e) calcination to the said raw powder at a temperature of at least 890 C. Such flue gas in such a way that the acid in the flue gas is being scrubbed and (f) the burning of the said flue powder into calcined cement. Which exhaust gas Was routed to produce the heat recovery powder. And exhaust gas treatment system 2. Process according to claim 1, where the aforementioned heating procedures in the combustion chamber These two were performed at temperatures in the range from 1050 ํ to 1200 ํ. 3. Process according to claim 1, where at which time of such retention of the said flue gas in The aforementioned second combustion chamber is at least 4 seconds. 4. Process according to claim 1, where the aforementioned heating procedures in the combustion chamber The two were performed at temperatures in the range from 1050 to 1200 C and retention time. The said flue gas in the aforementioned second combustion chamber is at least 4 seconds. 5. Process according to claim 1, where the aforementioned heating procedures in the combustion chamber Two of them were performed at high enough temperatures. And with a long enough retention time to have Removal of dioxins from the said flue gas 6. Process according to claim 1, where the calcined cement lumps The exhaust gases from the cooling process are transferred to the rotary kiln. These measures are used to maintain the temperature of the combustion process. 7. The process under claim 1 still consists of the production of fly ash from the incineration process. Until such powder, the fly ash transfer And the aforementioned flue gas in the aforementioned preclassiner goes to the boiler, to generate heat from there Cooling the fly ash And the flue gas, the fly ash is transferred back to the pre-calciner for the production of calcined cement. The abrasive flue gas is about 150 ํ C. And the emissions of the said exhaust gas to the environment. 8. The process of claim 1 still consists of fly ash production from the incineration process. Until such powder, the fly ash transfer And such flue gas to the boiler And procreation Electricity by heating from there and the accumulation and conversion of the cooled fly ash. It is a slurry lime for use in semi-dry scourers. 9. The process for the homogenization of calcined cement by combustion of solid waste, consisting of (a) the burning of such solid waste in a rotary furnace to produce flue gas. (B) the direct transfer of the flue gas to the second combustion chamber (c) the further heating of the flue gases to a very hot temperature from 1050 ํ C to 1200 ํ. In the presence of oxygen in the aforementioned second combustion chamber under intense convolution and for a sufficiently long retention time to achieve the absolute complete combustion of such flue gas. And to generate very hot flue gases from there (d) the transfer of such very hot flue gases to at least one cement pre-calciner. The pre-calciner contains cement, raw powder (e) calcination to the said powder at a temperature of at least 890 ํ C. Such hot flue gases are in such a way that the acid in the extremely hot flue gases is scraped and (f) cooled to about 400 ํ in the steam boiler. (G) abrasion of the aforementioned cooled exhaust gases at approximately 150 ํ (h) of such abrasive flue gas filtration. It is then filtered to the environment and (j) the incineration of the sintered raw powder to lumpy cement.
