1. What is plasma?
Plasma is an ionized gas-like substance made up of electrons and electrons that have been deprived after partial electrons are ionized. This is the fourth state of matter, except for solids, liquids, and gases. The plasma is a good electrical conductor that uses a cleverly designed magnetic field to capture, move, and accelerate the plasma. The development of plasma physics provides new technologies and processes for the further development of materials, energy, information, and environmental space science.
The seemingly “mysterious†plasma is actually a common material in the universe. Plasma exists in the sun, stars, and lightning, and it accounts for 99% of the entire universe. People have now mastered the use of electric and magnetic field generation to control the plasma. For example, welders use high temperature plasma to weld metal. Plasma can be divided into two types: high temperature and low temperature plasma. The above mentioned is a high temperature plasma. Low-temperature plasma is now widely used in a variety of production areas. For example: plasma TV, baby diapers surface waterproof coating, increase beer bottle barrier. More importantly, the use of etching in computer chips has made the Internet age a reality.
High temperature plasma occurs only when the temperature is high enough. The sun and stars constantly emit this plasma, making up 99% of the universe. Low temperature plasma is a plasma that occurs at room temperature (although the temperature of the electrons is high). The low-temperature plasma body can be used for surface treatment such as oxidation, denaturation, or precipitation coating treatment on organics and inorganic substances.
2. Our low-temperature plasma technology We generate low-temperature plasma by two methods. One is the PEM solid-state electrode electrolysis pure water technology and DC electric field technology. According to the requirements of different fields, we use different generation technologies. PEM electrolytic pure water: fresh food, fresh flowers; air and water disinfection; disinfection of medical appliances; DC electric field: factory flue gas treatment
2.1 PEM Electrolytic Purified Water Technology Based on electrolysis of pure water and nano-hybrid technology, we successfully developed a low-temperature plasma generator - lower cost plasma and its secondary product ozone, which breaks through the limit concentration of general ozone and passes Nanotechnology mixes ozone and other active ions well with water to enhance the treatment effect. The treated water and air are aseptic and odorless; the pesticide residue in fruits and vegetables and meat can reach 100% elimination rate. Current low-temperature plasmas and ozone generators are technologies that use ionized air and oxygen. Such devices are complex in structure, expensive, and have low ionization efficiencies. The concentration of ozone generated is not sufficient to kill all bacteria. Effect. At the same time when ionizing air, harmful gases such as nitrides are generated. There are also a few manufacturers using PEM electrolytic water technology, but because of the use of platinum as a catalyst, so the price is high.
Compared with turbine technology, the use of nanotechnology for water-air mixing is another competitive advantage of our products. The most famous turbine technology is Japan's Nikoni pump, which, in addition to not fully mixing ozone active substances with water, affects the bactericidal effect, and the expensive price of 12,000/station also loses its price advantage. If our plasma generator produces more than 100,000 units per year, the cost is 50 yuan per unit. Its operating costs are only utilities, and the cost is very low.
2.2 The application of DC electric field plasma generation technology in the removal of flue gas After many colleges and research institutes researched on low-temperature plasma discharge and electron beam purification flue gas, these two technologies have the following advantages over traditional technologies: Simultaneous removal of sulfides and Nitrides, no recontamination of the water during the dry process, by-products are highly valuable fertilizers that do not require catalysts, lower construction and operating costs. How the plasma technology operates:
The chimney wall brick (patent) is a negative electrode, and the central wire is a positive electrode. The operation is to form a DC electric field. The DC electric field generates low-energy electrons (compared to the electron beam method). The electrons are accelerated in the electric field and collide with the particles in the flue gas passing through the electric field, undergoing reactions such as adsorption, oxidation, and splitting, losing energy, and returning to low energy. State, then proceed to the next cycle.
The dust particles that have been adsorbed with high-energy electrons will be charged and attracted to the opposite electrode to achieve the dust removal effect. The dust removal rate reaches 99%.
When the electrons are accelerated, they collide with the gas molecules N2, O2, H2O, CO2As and transfer energy to them, forming atoms such as O, N, OH, etc., electrons and electrons, and activated molecules. These electrons and ions, ions and The ion- and electron-separated reaction proceeds with the next active molecule (eg, HO2, etc.), a large amount of O, O2-, OH, H, and O3 plasmas, oxidizes SO2 and NO to NO2, N2O5, SO3, or generates a suspension. substance. The reacted gas is pumped into another reaction tank by a special pump. This type of military pump can pump gas into the water with a strong impulse to form a milky shape, which ensures that the gas does not overflow and reacts with the substance in the reaction tank.
Ammonia (NH3) is introduced into the reaction tank to convert SO2 and NOx into NH4NO3 and (NH4)2SO4 compost. After the above reaction, a nitrogen removal effect of 99% was achieved and the emission of sulfur dioxide was less than 100 mg/m3.
What are the advantages of this low temperature plasma technology compared to electron beam? Plasma technology can transfer energy more efficiently, producing active O, OH, HO2 ions, and SO2. In the electron beam method, the high-energy electron beam wastes energy because it ionizes N2, because the effect of ionizing N2 is lower than ionizing O2. In addition, the electrons that lose energy become low-energy electrons and cannot be accelerated by the cycle. Therefore, it is also One of the reasons for wasting energy.
3. Compared with MAP (Modified Atmosphere Plastics) and MAP (atmosphere adjustment method)
The modified atmosphere method is a commonly used method in foreign countries. It is to achieve a balance by raising carbon dioxide, reducing oxygen, and then placing it in special film packaging to form a high-humidity environment and inhibit the secretion of ethylene, thus delaying the ripening of fruits and vegetables. And the softening of the organization, to reach a longer period of price. This system keeps the cell structure intact, reducing or inhibiting the growth of bacteria and mold. The atmospheric adjustment method can extend the period of goods price. To see it, there must be devices that meet the requirements of a balanced environment, such as oxygen separators, instruments that generate carbon dioxide, special films, and high demands on operators. Such an expensive price allows China’s developing countries cannot afford it.
The modified atmosphere method only solves the problem of extending the price of goods, but it cannot solve the problem of pesticide residues that plague many countries' food exports. 4. EWM-NM split-type low-temperature plasma vacuum decompression refrigeration fruits and vegetables food preservation technology integrated PEM Electrolytic pure water and nano-technology research and development of the plasma generator is our core technology. Utilizing a plasma generator, we successfully developed the "EWM-NM subassembly-type low-temperature plasma vacuum decompression refrigeration fruit and vegetable food preservation technology" for the preservation of food and flowers.
This system is combined with more than 10 patented technologies. The flowers, fruits and vegetables, meats, etc. to be treated are placed in the best stainless steel eggs (patented), subjected to vacuum, cooled, rinsed, and plasma treated - to kill internal and external bacteria, decompose secretory or residual internal and external Chemicals such as ethylene, pesticides, etc., after processing combined with ordinary film packaging, can achieve a long period of value. For example, the value of a rose is 60 days, and that of a Chinese peach is 40-45 days. Some vegetables can reach 90 days.
5. The application of low-temperature plasma preservation technology.
Pesticide residues caused China's 2003 agricultural exports alone to suffer losses of US$9.5 billion. In response to the current problem of excessive pesticide residues in agricultural products, relevant experts have jointly developed “plasma vacuum decompression solution for cold storage and preservation of pesticide residues†to provide terminal solutions for the removal of pesticide residues in agricultural products. Under normal farming conditions, after the treatment of this technology, pesticide residues from agricultural products can be released and the shelf life of agricultural products can be prolonged. For China's agricultural products to enter the international market unimpeded, across the green barriers to provide technical support.
The price advantage of Chinese products is indisputable. Its vegetable cost is only 1/8-1/5 of the world average. After China's accession to the WTO, China has huge room for development due to its advantages of low cost and high output. However, the current low-quality varieties and low-level treatment technologies have made the quality and packaging of processed vegetables in China unable to meet the requirements of the international market. The current processing technology can not effectively remove the pesticide residue on vegetables, thus forming a difficult technical barrier to export.
Our low-temperature plasma technology, combined with other compounding techniques, kills microorganisms that exist inside and outside of vegetables and decomposes them by 100%. The treated vegetables were stored at 0-3°C for 30-50 days and were still fresh. Therefore, this technology can not only enable vegetables to meet international export inspection standards, but also enable some of the valuable varieties of vegetables that could only be exported by air to be shipped to the sea, thus consolidating the price advantage of our products.
