Shanghai launches a new generation of innovative environmentally friendly small and medium-sized hydroelectric power generation systems

The innovative and environmentally-friendly water turbine system introduced by Shanghai can minimize the impact of environmental protection on hydropower development, maintain ecological balance, and improve the mechanical performance of hydropower generation systems and improve economic efficiency. The innovative environmentally-friendly water turbine system is designed to reduce the downstream water quality by using the “upward free water” design to eliminate liquid flow cavitation, blade vibration and high-pressure shaft sealing.

The upward-diffusing rotor passage allows the tailwater kinetic energy to be recovered without the draft tube. The use of a drum-shaped needle valve to control flow (instead of a conventional vane shutter) simplifies the flow control mechanism and operating procedures, reducing damage to fish. The modular assembly has resulted in a considerable reduction in equipment cost, assembly time, maintenance requirements, and power plant construction time and cost of the new turbine. Especially suitable for the development of small and medium-sized, and micro-hydropower.

According to the Shanghai Intellectual Property Service Center, the invention has successfully carried out model experiments at Iowa State University and Tsinghua University in China, and optimized the prototype design using fluid dynamics calculation (CFD) to achieve high efficiency. Running.

1. Raw material pulverization: Raw materials are mainly divided into two categories, starch and fat. Starch is mainly various grains. Its pulverization can be achieved by ordinary pulverizers. It only needs to ensure the fineness and clean raw materials during the pulverization process. Hygiene can be. Use a colloid mill to pulverize into separate packs or puree, and the meat only needs to be pulverized into meat puree or powder with a colloid mill, and then added to the grain powder and stirred evenly.
2. Raw material mixing: The mixing equipment has two functions, one is to mix all kinds of raw materials evenly, and the other is to adjust the moisture and humidity. It is generally a vertical rapid mixer: the mixing time is short, the mixing is completed quickly, and the machine is used before the humidity of the raw material changes significantly, which ensures the uniformity and quality of the puffing of the dog food particles. The disadvantage is: the single-cylinder mixing capacity is small, and it needs to be stirred all the time during the production process.
3. Raw material extrusion, puffing and curing molding: The twin-screw extruder extrudes and extrudes under high temperature and high pressure, and produces dog food and cat food particles of different styles and shapes by changing different molds. For different raw material ratios and humidity, it is necessary to adjust the temperature and screw speed of different regions and the feeding speed of the feeder to ensure that the produced dog food particles are of high quality and good appearance.
