Garbage burning fly ash sintering harm-eliminating resource-utilization treatment system

The invention relates to a garbage burning fly ash sintering harm-eliminating resource-utilization treatment technology. According to the invention, garbage burning fly ash is mixed with premixed coal and auxiliary materials; the mixture is granulated and shaped; and the material is dried and is sintered in a rotary kiln. During the sintering process, when the temperature is increased and a coal ignition point is reached, the premixed coal is spontaneously combusted. Therefore, external coal dose can be reduced. Initial combustion of the premixed coal can provide a reductive atmosphere, such that dechlorination and detoxification of dioxin in fly ash can be benefited. Large amount of gas is produced by subsequent combustion, such that dust pores and holes are produced on inner and outer parts of the sintered body, and heavy metal volatilization can be promoted, and fly ash sintered body with low heavy metal content and leaching amount can be obtained. The sintered body has no potential harm to the environment, such that fly ash harm-eliminating and resource-utilization are sufficiently realized. During the processing process, smoke and secondary fly ash production amounts are low, and heavy metal and acidic component contents are high. In deacidification and heavy metal stabilization processes, agent utilization rate is improved. Compared with a traditional original fly ash curing / stabilizing process, a landfill amount can be reduced by 80-90%, such that pressure caused by serious landfill space shortage can be effectively relieved.

Waste incineration fly ash sintering reduction treatment technique

The invention relates to a waste incineration fly ash sintering reduction treatment technique which is especially applicable to treatment and disposition of waste incineration fly ash of which the salt content is lower than 20%. The fly ash is added with a dechloridation fusing assistant to intensify the volatilization of heavy metals and the decomposition of dioxin, heavy metals and chlorine salt are intensively concentrated in secondary fly ash within a relatively low temperature range, and then the secondary fly ash is washed by water so as to further realize concentration of pollutants and reduction of the fly ash. The water-washed fly ash is returned to a rapid sintering device so as to completely degrade dioxin type pollutants; water-washing liquid is evaporated and concentrated to recycle the salt by using the afterheat of a sintering system, the concentrated liquid and mud obtained by evaporation and the obtained sintered body are safely buried or recycled. The treatment technique disclosed by the invention is relatively simple in overall process and equipment, the energy consumption and the treatment cost are relatively low, the environmental friendliness of the obtained end product is improved, and the long-term potential impacts of the fly ash on the environment are minimized.

The continuous gravitational potential energy power generation device includes a water storage cylinder, the upper end of the water storage cylinder is connected with a floating ball discharge pipe, and the lower end of the water storage cylinder is connected with a floating ball inlet pipe; the inner side of the floating ball inlet pipe is equipped with a sealing sleeve with a small upper mouth and a large lower mouth; The upper port of the float inlet pipe is connected with the float cone inlet; there is a gravity transmission mechanism at the port of the float ball discharge pipe. The upper bearing seat and the lower bearing seat of the gravity transmission mechanism are supported on the upper bearing seat and the lower bearing seat. The upper and lower rotating wheel pairs are equipped with transmission parts; the hanging baskets are installed at intervals on the transmission parts; the hanging baskets are matched with the floating ball; the port of the floating ball discharge pipe is located at The uppermost hanging basket in the gravity transmission mechanism; the port of the floating ball discharge pipe is provided with a baffle for controlling the discharge of the floating balls at intervals; the upper rotating wheel pair and / or the lower rotating wheel pair are connected with a generator; under the gravity transmission mechanism There is an inclined floating ball sliding groove. The upper end of the floating ball sliding groove is provided with a protrusion for the collision of the floating ball. The lower port of the floating ball sliding groove is located directly above the conical inlet of the floating ball. Control the floating balls to be discharged at intervals.
