Reporter: Based on our understanding of your energy-saving technology innovation project and the introduction of your invention project in relevant newspapers and magazines, could you please tell us why you innovate engine technology? Han: I have been interested in engines, transmissions and new vehicles since I was in middle school. Later I learned that the efficiency of engines is not very high. After I started working in 1983, I decided to conduct research on improving engine efficiency and strive to make breakthroughs. Several different high-efficiency engine solutions were conceived.
Of course, because the early technical conception plan was not in the most reasonable state in terms of structure, it was not successful. This period lasted for a long time. Since there was no better breakthrough in conception, I was also very distressed. , not willing to give up like this. I have collected a lot of technical information on engines at home and abroad. Seeing that there are no essential technological breakthroughs abroad, I think it is still necessary to continue to innovate to improve engine efficiency. At this time, my ideas are very clear. I just need to conceive of a A new high-efficiency engine can be invented with a technical solution that can maximize the recovery and utilization of engine exhaust heat and is structurally reasonable.
By the end of 1999, I finally had a unique idea on how to better recover. Since I have made breakthroughs in key areas, I have been working hard to improve engines of different structural types from 2000 to now. Now, I have completed four different types of power units: internal combustion, external combustion, piston type and turbine type. innovative design. There are intercooled isobaric heat-absorbing air turbines suitable for energy-saving power plants, new fuel-saving gas turbines suitable for large aircraft, and valveless cylinder-rotating intercooled heat recovery internal combustion engines for automobiles.
Reporter: Judging from your experience, you did not study engines, nor do you work in an enterprise in this field, but you have innovated a variety of energy-saving engines with different structures, which is somewhat inconsistent with people's conventions. Imagine.
Han: In fact, if we only understand many human technologies from their essence and figure out their principles and structures, it will not take much time. For example, the currently widely used power devices are piston internal combustion engines, gas turbines, and coal-fired steam power systems in power plants. It only takes a few months to understand these technologies. Of course, if you want to engage in a career in this field, it is not that simple. You have to be admitted to relevant colleges and universities and be hired by companies in this field. If companies do not pay attention to research and development, you will still not be able to engage in technological innovation if you want to. condition.
If you understand engine technology from a conventional perspective, you will feel that this technology is very complete, and professional technicians can confidently design engines for various purposes. But looking at the existing engine technology with a more critical eye, its fuel consumption is still high, the efficiency index is not ideal, and as much as 50-60% of the heat is lost in cylinder heat dissipation and exhaust gas. Of course, there are many scientific and technical personnel working hard to improve engine efficiency, but when it comes to breaking through tradition and engaging in major innovations, it is not necessarily the professional technicians in the engine field who succeed in the end. However, 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 get involved in detail. Social development and scientific and technological progress will generate many new problems and different technical needs, which provide new markets for inventions and creations. If you are interested in a certain technology, can identify its potential shortcomings, dare to think innovatively, and are not swayed by the traditional views of expert authority, you may be able to find better ways to overcome the shortcomings of existing technology.
Reporter: Your technology is still patented, and some newspapers and magazines are also helping to appeal for funding problems.
Talk about your process of finding funding. difficulties encountered.
Han: Let’s talk about patents first. Due to various reasons, I have encountered great difficulties in finding funds, and the funding problem has not been solved yet. Patented technology, especially patents in the mechanical field, can be accurately evaluated on the creativity, practicality and technical value of patented technology by calming down and carefully reasoning and analyzing it.
For example, many scientific and technological innovation funds only support the innovative behavior of enterprises, and many technologies must complete pilot tests and be put on the production line before they can receive support. In this way, funding for scientific and technological innovation has deviated from the starting point of innovation. Many science and technology parks have funds to subsidize individuals, but you have to be a "higher-ranking" returnee from overseas.
As an individual inventor, due to the time limit for applying for a foreign patent, you will lose the qualification to use your patent to occupy foreign markets after the time limit. My patented technology for energy-saving power plants is expected to earn nearly 10 billion US dollars in patent revenue abroad, but now I can’t even find a few hundred thousand in starting capital. I’m not qualified to apply to the national science and technology department. The investment company is only made in you. Investment will be made at a certain stage after the product is launched, and the bank cannot borrow it.
Reporter: Tell us about the technological innovations, energy-saving effects and impact on existing technology in your energy-saving power plant.
Han: Regardless of the internal combustion or external combustion power device I invented, it all includes an isobaric heat recovery or isobaric heat absorption system composed of a gas distribution device. The intercooling isobaric recuperation cycle in the internal combustion engine can basically absorb the heat in the exhaust and convert it into power for output in the next cycle. Coupled with the use of thermal insulation technology for the cylinder, it can greatly reduce engine heat dissipation and The exhaust loss makes the effective efficiency reach 65-70, surpassing the fuel cell system that people have hoped for, and becoming the most efficient vehicle engine. In automotive fuel cells, there is a thermal reaction loss of about 50%, so there is no need to develop high-cost automotive fuel cell technology. As for the internal combustion intercooled isobaric regenerative gas turbine, because its efficiency has been greatly improved, it can be used to replace the turbofan power device in the existing large aircraft, providing us with a world-first method for the future development of large aircraft. Highly efficient and energy-saving power unit.
In an externally fired intercooled isobaric heat-absorbing air turbine, the intercooled isobaric heat-absorbing cycle can basically absorb all the heat generated by the boiler, and at the same time, the high-temperature heat after work is discharged from the turbine The air can be directly returned to the boiler to participate in combustion, so that the turbine exhaust heat is directly recovered, so that the heat loss in the entire cycle is very small, and the efficiency can easily reach 70. When it is used as a power plant power unit, a large amount of coal resources can be saved. At the same time, the emission of carbon dioxide gas is greatly reduced. If the world's 1.31 billion kilowatt old coal-fired power plants before 1999 are transformed, the world can save 1 billion to 1.5 billion tons of coal every year.
Another point is that after using this new type of air turbine as the power plant, the power generation efficiency is not closely related to the power plant capacity, so the small thermal power plants that are currently shut down should not be blown up. It can be shut down first and then re-activated after being modified with a new and efficient intercooled isobaric heat-absorbing air turbine in the future.
