Of course, the early technical conception scheme was not the most reasonable in structure, so it was not successful. This period of time lasted for a long time. Because there is no better breakthrough in conception, I am also very distressed and unwilling to give up like this. I have collected a lot of technical information about engines at home and abroad, and found that there is no substantial technical breakthrough abroad. I think we should continue to innovate and improve engine efficiency. At this time, my own thinking is very clear. As long as I conceive a technical scheme with reasonable structure that can maximize the recovery of engine waste heat, I can invent a new type of high-efficiency engine.
By the end of 1999, I finally had a unique idea on how to regenerate heat better. Because of the breakthrough in key places, I have been trying to improve different types of engines since 2000. Now, I have completed the innovative design of four different types of power devices: internal combustion, external combustion, piston and turbine. There are medium-cooling isobaric endothermic air turbines suitable for energy-saving power plants, new fuel-saving gas turbines suitable for large aircraft, and rotary intercooled regenerative internal combustion engines with valveless cylinders for automobiles.
Reporter: According to your experience, you have never studied engine major or worked in an enterprise in this field, but you have innovated a variety of energy-saving engines with different structures, which is not in line with people's conventional imagination.
Han: Actually, it doesn't take much time for many human technologies to understand it in essence and figure out its principle and structure. For example, at present, only piston internal combustion engine, gas turbine and coal-fired steam power system are widely used in power plants, and it takes only a few months to understand these technologies. Of course, if you want to pursue this career, it's not that simple. You have to be admitted to relevant colleges and universities, and you have to be hired by enterprises in this field. If enterprises do not attach importance to R&D, you still have no conditions to engage in technological innovation.
If we understand the engine technology from the conventional mentality, we will feel that this technology has been very perfect, and this professional technician has been able to design the engine with great confidence. However, looking at the existing engine technology with a more critical eye, its fuel consumption is still large and its efficiency index is not ideal. The heat loss caused by cylinder heat dissipation and exhaust is as high as 50-60%. Of course, many scientific and technical personnel have made great efforts to improve the efficiency of the engine, but not necessarily the professional and technical personnel in the engine will successfully break through the tradition and make great innovations. But modern technology is becoming more and more complex, and many technologies have been carefully divided. More specific technical improvements can only be completed by professionals, and it is difficult for outsiders to specifically intervene. Social development and scientific and technological progress will produce many new problems and different technical requirements, which will provide a new market for invention and creation. If you are interested in a certain technology, you can find its potential shortcomings. At the same time, you dare to think creatively and are not influenced by the traditional views of expert authority. Maybe you can find a better way to overcome the shortcomings of the existing technology.
Reporter: Your technology is still in a patented state, and some newspapers and magazines are also helping to appeal for solving the funding problem.
Talk about the difficulties you encountered in the process of finding funds.
H: Let's start with patents. Now, due to various reasons, we have encountered great difficulties in the process of finding funds, and the funding problem has not been solved so far. Patented technology, especially patents in the field of machinery, can be accurately evaluated for its creativity, practicality and technical value as long as it is carefully reasoned and analyzed. For example, many science and technology innovation funds only support the innovation behavior of enterprises, and many technologies can only be supported after completing the pilot test and embarking on the production line. In this way, the funding for scientific and technological innovation deviates from the starting point of innovation. Many science parks have funds to support individuals, but what are you going to do? Superior? Returnees.
As an individual inventor, because there is a time limit for applying for foreign patents, after the time limit, he loses the qualification to occupy foreign markets with patents. My patented technology for energy-saving power plants is expected to earn nearly $10 billion in patent income abroad, but now I can't even find hundreds of thousands of upfront funds, and I am not qualified to apply to the national science and technology department. Investment companies will only invest at a certain stage after you have finished the product, and you can't borrow it.
Reporter: Tell us about the technological innovation, energy-saving effect and the impact on the existing technology of your energy-saving power plant?
Han: Both the internal combustion and external combustion power devices I invented include an isobaric regenerative or isobaric heat absorption system composed of gas distribution devices. The intercooling isobaric regenerative cycle in internal combustion engine can basically absorb the heat in exhaust gas and convert it into power output in the next cycle. In addition, by adopting heat insulation technology for the cylinder, the heat dissipation and exhaust loss of the engine can be greatly reduced, and the effective efficiency can reach 65-70%, which exceeds the desired fuel cell system and becomes the most efficient vehicle engine. There is about 50% thermal reaction loss in automobile fuel cells, so it is not necessary to develop high-cost automobile fuel cell technology. For the internal combustion medium-cooling isobaric regenerative gas turbine, because its efficiency has been greatly improved, it can be used to replace the turbofan power plant in the existing large aircraft, providing the world's first high-efficiency and energy-saving power plant for our future development of large aircraft.
In the external combustion type air turbine with medium cooling and equal pressure heat absorption, the heat generated by the boiler can be basically absorbed by the medium cooling and equal pressure heat absorption cycle, and the high temperature air discharged by the gas turbine can directly return to the boiler to participate in combustion, so that the residual heat of the gas turbine can be directly recovered, and the heat loss of the whole cycle is very small, and the efficiency can easily reach 70%. When it is used as a power plant, it can save a lot of coal resources and greatly reduce the emission of carbon dioxide gas. If the old coal-fired power plants with 1.3 1 100 million kilowatts in the world before 1.999 are reformed, the world can save1.00 billion-1.500 million tons of coal every year.
One more thing, because this new type of air turbine is used as the power plant, because the correlation between power generation efficiency and the capacity of the power plant is not very great, the small thermal power that is currently shut down should not blow up, so it can be shut down first, and then it can be reused after being rebuilt with a new and efficient medium-cooling isobaric heat-absorbing air turbine.
