The invention discloses a modification method for semi-dry sintering flue gas desulfurization ash. The modification method comprises steps of grinding and sieving the semi-dry sintering flue gas desulfurization ash, then steeping in deionized water for modification, and steeping in 5-20% oxalic acid for modification. The modification method not only can well modify the desulfurization ash, lower the content of Cl and S in desulfurization ash, and collect and reuse S and Cl in the desulfurization ash so as to alleviate the problem of deficiency of S and Cl to a certain degree; comprehensive utilization of the desulfurization ash in construction materials such as cement and concrete can be realized so as to lower the production cost of the construction materials, and the desulfurization ash can also be used in medical treatment. The modification method is simple, efficient, and low in cost, and has a broad prospect.

This application relates to a water collection and purification device for sunken green belts on municipal roads, which includes a collection box and a drainage pipe, and also includes a water collection box, a rainwater reuse device and a lifting device. The collection box and the water collection box are connected by a connecting pipe. There is a partition board inside the water tank. The partition board separates the water collection tank into the water collection area and the drying area. The rainwater reuse device includes a suction pipe, a water pump, a water outlet hose and a nozzle. The water pump is set in the drying area. One end of the suction pipe Connect the water pump, and insert the other end into the water collection area through the partition plate. One end of the water outlet hose is connected to the water pump, and the other end is connected to the nozzle. The lifting device includes a cover plate and a driving device. The driving device is set in the drying area. The output of the driving device The end is connected to the cover plate, the cover plate blocks the mouth of the water collection tank, and the nozzle is connected to the side wall of the cover plate near the bottom side of the water collection tank. The application improves the problem that rainwater is not collected and utilized, and water resources are wasted.

The invention discloses a raw material collection structure for preparing urokinase. The raw material collection structure comprises a urinal, the urinal is fixedly installed on a wall through an installation support, a urinating cavity is formed in the urinal, a rotating cavity is positioned below the urinating cavity and communicated with the urinating cavity, a rotating shaft is rotatably mounted in the front end wall and the rear end wall of the rotating cavity and in power connection with a waterproof motor fixedly mounted in the front end wall of the rotating cavity, a rotating plate isfixedly mounted on the rotating shaft, water retaining plates extend upwards and are symmetrically arranged in the front and the rear of the rotating plate, a left through groove and a right through groove are formed in the left end wall and the right end wall of the rotating cavity, a bottom through groove is formed in the bottom wall of the rotating cavity, a sewage draining pipe connected witha sewage draining system is fixedly mounted at the lower end of the bottom through groove, a collection pipe connected with a collection tank is fixedly arranged on the right side of the sewage draining pipe, and a left connecting pipe and a right connecting pipe are fixed outside the left through groove and the right through groove and communicated with the sewage draining pipe and the collection pipe.

The invention relates to a stacked rotary electrostatic generator, belonging to a micro energy system, comprising a power collection assembly, a bearing seat plate, a fixed cylinder, a moving disk assembly, a static disk, a connecting screw assembly, an oil seal bearing and a rotating shaft; the power collection assembly The component is fixed on the rotating shaft, and driven by external force, the rotating shaft and the moving disk assembly fixed on the rotating shaft are driven to rotate synchronously, so that the electret electrode on the moving disk and the working electrode on the static disk are positively aligned. Periodic changes in the area cause periodic changes in the capacitance value, thereby generating electrical signals and outputting them to external circuits. The output electric energy can be applied to the power supply of various wireless sensor nodes or as a real-time monitoring of the flow rate of the environmental fluid. Since the positive and negative electrets are arranged at equal intervals, the charging efficiency on the surface of the moving disk is greatly improved, and the output power of the generator is increased.
