2. It should be noted that at present, the development of microwave application in a specific era has caused several problems:
● There is a gap in stability compared with foreign equipment.
Low backward manufacturing technology is difficult to form economies of scale.
● Insufficient connection with other technologies.
● The new achievements of microwave technology have fallen into the boudoir, which can't be transformed and can't get due economic benefits.
The establishment of microwave application engineering research center, focusing on the in-depth development of microwave engineering and the mutual penetration and combination of various applied disciplines, can find a clear intersection of microwave law and application law and explore major industrial projects. Specifically, we should try our best to find a method compatible with traditional technological process and microwave technology. On this basis, we will develop new equipment and gradually push the results to industrialization.
3. The application of microwave has changed from heating and drying to high-tech application, which has exposed many problems in laboratory application and must be effectively solved.
(1) That is to increase the output stability of microwave power source, emphasize power consistency, millisecond modulation means and modulation repetition accuracy, and develop ultra-high power microwave power source.
(2) Improve the quality of high-power micro-transmission elements and power proportional sampling elements.
(3) The effective methods of process parameter sensing and closed-loop control are studied.
(4) In order to adapt to the new development direction of application, it is necessary to study various design methods of application, so that the design of application has high compatibility and adaptability. In order to gradually design pilot equipment for the new direction of various industries, it is necessary for the microwave application engineering research center to strengthen the development of these equipment units by integrating successful unit technologies into building blocks.
4. The microwave application engineering research center must make itself have the ability to organize medium-scale experiments quickly, thus reducing many projects and staying in experiments for a long time without turning to production. Therefore, the microwave application engineering research center must have the ability of large-scale experiments, so that the microwave application engineering research center can organize large-scale experiments in its place first when necessary, and make the design of super-large-scale industrial projects more reliable.
5. The great significance of establishing the research center of microwave application engineering lies in transforming the scientific research achievements of universities, research institutes and laboratories into industrial achievements and playing the role of a bridge, thus overcoming the situation that many people only see flowers but have no achievements for a long time.
Second, the research content and objectives:
1. Contact magnetron manufacturers to keep their products with long life, high reliability and high efficiency, and overcome the unsatisfactory situation of declining product quality at present. On this basis, the microwave power source with long life, high reliability and high stability is studied. Develop a complete set of design methods for high power microwave modules and heaters, including gas phase, liquid phase and solid phase treatment. And a vacuum drying applicator. Develop efficient and environmentally friendly drying equipment to replace some drying plants with steam and oil boilers as energy sources. Develop a variety of sensing methods and closed-loop control.
2. Study the ways of pilot test and industrialization from the following aspects:
(1) research on microwave plasma nano-preparation, powder technology, microwave plasma sterilization technology, eye endoscope sterilization equipment, surgical material sterilization equipment.
(2) Develop production equipment combining microwave petroleum high-temperature sintering ceramics with traditional methods, so as to shorten the sintering time of ceramics to one third of that of traditional electrothermal methods, improve the solid-state reaction and accelerate the quality of solid-state reaction.
(3) Developing microwave crude oil demulsification equipment to dehydrate water-in-oil emulsion to reach the standard; Develop microwave cracking equipment for petroleum waste and high pour point oil to make these waste oil and high pour point oil become high quality oil.
(4) Develop microwave-assisted pyrolysis equipment for minerals, so that the non-ferrous metal sulfide ore used in the equipment can be converted into non-ferrous metal oxides, and the problems of non-ferrous metal sulfide ore and sulfur-bearing gold ore in Yunnan can be solved. This method can be extended to microwave heating of carbon-containing iron ore pellets, and a new blast furnace ironmaking process is innovated.
(5) Systematically study the microwave-assisted extraction technology to speed up the extraction and improve the extraction quality. On this basis, develop a variety of extraction technologies, speed up extraction, improve extraction quality, and on this basis, develop a variety of extraction equipment. Widely used in Chinese medicine, pharmacy, spices, chemical industry and other industries. The modernization of traditional Chinese medicine pharmacy is a major topic in China at present, and microwave extraction has more advantages than supercritical extraction. In addition, microwave can also be concentrated, sterilized and dried in the pharmaceutical field.
(6) Systematically study the low-pressure microwave drying technology, study various energy supply methods, explore the low-temperature dehydration process of various materials, and develop various vacuum drying equipment.
Third, short-term goals
The clear practical direction makes the infrastructure of microwave engineering itself must be improved. Through the specific projects of microwave application, the scientific research results will gradually turn to industrialization. The market prospect of microwave application is very promising. At present, there are several major projects that can be carried out, because we have mastered the core technology and can quickly open the market through efforts and obtain considerable economic benefits.
1, medical low-temperature microwave plasma sterilization, gastroscope, colonoscopy, plastic medical devices and other medical devices generally can not be sterilized at high temperature, but chemical liquid disinfection is easy to produce residues on the devices, which is potentially harmful to people, and virus cross-infection is easy to occur if the disinfection time is not enough. Medical low-temperature microwave plasma sterilization equipment can complete low-temperature or normal-temperature sterilization in a short time. At present, there is still a blank in China, and a few developed countries abroad use it, but the price is very expensive. The main technologies used in this topic are: microwave technology, plasma discharge technology, vacuum technology and micro-airflow control technology.
2. Pump microwave drying equipment: Heat pump drying technology is an advanced technology, and its biggest feature is high efficiency. It can dehydrate 3 ~ 5 kilograms (kWh) at a time, which is much lower than that of conventional steam drying. It has many advantages, but it consumes a lot of energy, and once it is dehydrated by electricity, it is only 0.5 kg. If these two technologies are combined, there will be great innovation in drying engineering. This kind of equipment is truly efficient, environmentally friendly and adaptable, and can replace many traditional drying equipment and enter all walks of life. The successful experiment of heat pump microwave drying has been reported, and foreign developed countries are preparing to develop and popularize it vigorously.
3. Wave chemical test equipment and microwave chemical engineering: The application of microwave in the chemical field has become a hot spot, involving not only drying and heating, but also catalysis, hydrolysis, digestion, incineration, desulfurization, demulsification of petroleum, dewaxing, thawing, material modification, ceramic sintering, vapor deposition, diamond film and rubber vulcanization. The technical transformation of the laboratory needs the power of engineering technology. At present, as far as microwave engineering technology is concerned, our designers have accumulated a lot of experience and are the strongest R&D team of microwave application engineering in China. For example, after the design of rubber vulcanization was modified last year, the performance of the whole machine reached the advanced level abroad. In less than a year, we sold Line 0, and the sales amount reached 1 ten thousand yuan. Domestic sales of microwave rubber vulcanization equipment from foreign manufacturers have been pushed to Guchi.
4. Microwave extraction equipment and complete sets of equipment: needless to say, modern Chinese pharmacy lacks complete sets of microwave extraction equipment in the market. Since the launch of microwave extraction tank last year, we have sold ten sets of equipment (but not complete sets). According to the analysis of market feedback information, there is a huge demand for large, medium and small complete sets of micro-extraction equipment. Microwave extraction is superior to supercritical extraction, ultrasonic extraction and chemical extraction, which is more in line with China's national conditions.
Four. conclusion
We have accumulated rich experience in the field of microwave engineering, leading domestic counterparts, and some aspects of microwave application technology are also in the international leading position. Over the years, it has helped various industries, universities and scientific research institutions all over the country to do a lot of research work, involving a wide range of disciplines and industries, and is a huge intangible asset. The establishment of provincial or national microwave engineering research centers and a certain amount of start-up funds can promote microwave application projects to enter the stage of scale economy in a certain period of time. There are hundreds of millions of employees in the microwave application engineering market in many developed countries every year. As a developing country, the prospects are very promising. The equipment price in foreign microwave application market is 7 ~ 8 times higher than that in China. As long as we do our best, it will not be a distant thing for microwave equipment to go abroad.
