The invention relates to a method for adopting waste derivative oversize material as substitute for cement kiln fuel, which is characterized in that the domestic waste in refuse reclamation station is separated and sorted, broken in packages, crushed and completely stirred and mixed, one part of the waste enters a precombustion furnace in the kiln tail of a cement kiln for combustion, while the other part of the waste enters the cement kiln from the kiln hood for combustion, thus the substitute fuel for cement production is produced. The invention has the advantages that the waste derivative oversize material having calorific value is adopted to substitute for industrial fuel in the cement kiln, thus resources of waste derivative oversize material are fully utilized, and coal energy resources are saved; simultaneously the cement kiln has the characteristics of high temperature, large carrying capacity, no residue after waste treatment and no secondary pollution, therefore the invention has the great advantages of energy saving and environmental protection.

The invention relates to a hydraulic multi-frequency ultrasonic generator. At least two connecting rods are arranged between an inlet plate and a base plate; a convergent nozzle extending inwards is processed at the center of the inlet plate; at least two inlet spring plates are arranged on the outer side of the nozzle; a barrier body is arranged at the center of the base plate; the length of the barrier body is not equal to that of the nozzle; a bottom spring plate is arranged at the outer side of the barrier body. A liquid medium disturbs and generates retroaction on jet flow near the nozzle by using the jet flow from the nozzle and a barrier with a certain geometrical shape; alternating pressure field and speed field are generated between the nozzle and the barrier body; vibration is generated to generate a sound wave, so as to improve and intensify the ultrasonic wastewater treatment effect. The nozzle and the barrier are different in length, and the corresponding inlet spring plate and the bottom spring plate are also different in length, so that the multi-frequency ultrasonic wave is generated, the ultrasonic frequency can also be changed by changing the lengths of the nozzle, the barrier body, the inlet spring plate and the bottom spring plate, and the adjustable frequency is achieved.
