Grand prize work

Free radical enhanced catalytic filtration device for treating various pollutants in flue gas (Zhejiang University);

China's energy consumption is growing rapidly, but pollutant emissions remain high, and the situation of emission reduction is grim, facing many pollutant control problems. At present, the flue gas control in thermal power plants generally adopts the method of separate cleaning, which leads to the complexity of the tail flue gas purification system and the increase of treatment cost.

In this paper, a scheme of synergistic multiple removal by free radical enhanced catalytic filtration is proposed. This technology organically integrates the functions of free radical oxidation, alkali absorption, chemical catalysis and bag filtration, so as to achieve the purpose of efficiently removing pollutants such as dust, SO2, nitrogen oxides, Hg and VOCs. The bright spot of this technology lies in the combination of plasma discharge and catalyst, which reduces the activation energy of catalyst and improves the removal efficiency. The catalyst composite cloth bag was developed by organically combining weaving and impregnation technology with filtration.

This technology can be applied to the emission control of industrial flue gas pollutants, which solves the problem that the existing single flue gas pollutant removal method can not meet the environmental protection emission standards, and at the same time provides a feasible scheme for realizing the coordinated removal of various pollutants in industrial flue gas, which plays a positive role in environmental protection.

Energy-saving automatic floor brushing machine (Dalian University);

This is a medium-sized full-automatic energy-saving floor brushing machine with simple structure, beautiful appearance, small volume, light weight, high cleaning efficiency, large water tank capacity and simple operation. This machine is suitable for cleaning hard floors in hotel lobbies, factory workshops, office areas, shopping malls and supermarkets, and can spray water, scrub and suck dirt at the same time. The horizontal movement of the brush is perpendicular to the direction of the car, and the cleaning effect is better. The mechanism is driven by an eccentric wheel driven by a shaft, not a motor, and integrates three functions of automatic sprinkling, floor brushing and drying, which can greatly reduce people's labor intensity and improve cleaning efficiency. The operation is simple and the touch pressure of the brush can be adjusted. The contact pressure of the brush can be adjusted in neutral gear, light gear and heavy gear, and it can be set as neutral gear on the way to the destination, which not only reduces friction, but also simply pulls the splint, selects the gear and then resets when shifting gears. The sprinkler switch is set to adjust. After the car, the operator can at any time.

Innovative design of small vertical axis wind turbine (Huazhong University of Science and Technology);

At present, as a kind of clean energy, the development of wind energy is mainly limited to large-scale grid-connected wind turbines, while the research on small-scale wind turbines is less. Based on the design of small wind turbine, a typical vertical axis blade (S-shape) is improved to obtain a more suitable blade form for small wind turbine.

The blades of traditional S-type vertical axis wind turbine are twisted into a whole by helix, which has some shortcomings. In this work, a new type of S-type wind turbine is designed by using computer simulation and wind turbine blade design technology, which makes up for the shortcomings of traditional S-type wind turbine.

High efficiency, energy saving and low thermal resistance LED light source (Huazhong University of Science and Technology);

Energy resources are the basis of economic development, but with the development of economy, a lot of energy will be in short supply, so energy conservation is the premise to ensure sustainable economic development. Implementing lighting energy-saving technology to save electricity is a way to save energy.

The basic principle of lighting energy saving should be to reduce the energy loss in the lighting system and make the most effective use of electric energy without lowering the visual requirements of the workplace. At present, the lighting system adopts manual switch, which often cannot be switched on and off in time, resulting in a lot of energy waste.

The LED intelligent lighting system designed in this system overcomes the above shortcomings, thus achieving the purpose of energy saving. First, pyroelectric infrared sensor is used to detect whether there is anyone in the room. If there is someone, turn on the LED light, otherwise turn off the LED light, so that the light can be automatically turned on and off, and the user can avoid forgetting to turn off the light and wasting electricity.

When someone is indoors, the LED has been turned on. After starting, the indoor light intensity will be automatically detected by the photoresistor, and then the brightness of the LED will be adjusted according to the resistance of the photoresistor. When the indoor light is strong, the brightness of LED lamps will decrease, otherwise the brightness will increase. If the brightness reaches a certain level during the day, the LED will automatically turn off.

Manual control function is added to the system, which is convenient for users to operate. Users can switch automatically and manually through the PT2262 remote control, and there are buttons to increase and decrease brightness, turn off and turn on lights. It provides great convenience for users.

Hybrid concept car based on hub motor (Zhejiang University)

Since the 20th century, energy and environmental problems have become increasingly prominent. As the main means of transportation, cars consume a lot of oil resources, and their exhaust emissions have become one of the main sources of air pollution. In this context, the development of new power vehicles has been paid more and more attention. A hybrid concept car based on hub motor is designed. The rear wheel is driven by a single-cylinder gasoline engine, and the front wheel is driven by two hub motors. There is no mechanical transmission between the two power systems. The concept of hybrid power is realized by "grounding", which saves the expensive transmission system on the existing hybrid car. The driving force of the hub motor integrated in the hub directly acts on the tire, which abandons the traditional mechanical transmission parts and reduces the mechanical transmission loss. The layout of the wheel is not constrained by the transmission system, which is beneficial to the layout of the whole vehicle structure. The control system of automobile power train is developed. The control strategy is: the vehicle starts at idle speed, the motor starts, and the low-speed pure motor drives. When the vehicle speed reaches a certain speed, the engine is turned off and the motor is turned off at the same time, which effectively utilizes the characteristics of low speed and large torque of the motor, avoids the engine from working in idle and low-speed working areas with poor fuel consumption and emission, and achieves the purpose of energy saving and emission reduction. In addition, the braking energy recovery technology is also studied, which converts some of the wasted energy during vehicle braking into electric energy and stores it in the battery, which has certain energy-saving effect.

Development of low energy consumption variable sprinkler irrigation unit and research on energy-saving water supply (Jiangsu University)

A low-energy variable spray automatic sprinkler system is designed, which mainly includes variable nozzle and spray pump. This paper analyzes the energy consumption of unit operation, and puts forward some suggestions on determining the characteristic curve of water pump and pipeline. Through theoretical analysis, the relationship between the range and the required flow rate and working pressure is obtained under the corresponding nozzle rotation angle when spraying with any shape. According to the characteristic curve of the pipeline, determine the required flow and lift of the pump when it runs at the working point. Through variable frequency speed regulation, the requirements of the pump are realized, the spraying of arbitrary shape variables is realized, and the effect of energy saving is achieved at the same time. The LabView simulation test of the unit shows that variable frequency speed regulation can make the sprinkler irrigation system realize square variable spraying. The energy-saving benefit of variable sprinkler irrigation unit is analyzed. Assuming that the water consumption of sprinkler irrigation in China is not increased, only the current sprinkler irrigation system is replaced by variable sprinkler irrigation units with low energy consumption and its energy-saving water supply strategy, which can bring an average of 2. Social benefits of 5.5 billion m3 irrigation water. According to the annual demand for sprinkler irrigation units increasing by 5%, it can bring economic benefits180,000 yuan and 0. 27~0。 The energy efficiency is 450,000 kilowatts. This design combines variable technology with energy-saving water supply strategy for the first time, so that the sprinkler irrigation unit can reduce energy consumption while realizing variable spraying, and achieve the effect of water saving and energy saving.
