Creativity comes from life

The 11th 'National Technical Innovation Contest' award (2010-2011) has been awarded to many highly applicable solutions such as using rice husk as fuel, gas-saving equipment, and replacing coral. bone.

Prof. Dr. Dang Vu Minh, Chairman of Vietnam Union of Science and Technology Associations, Head of the Organizing Committee of the competition: The creators' prizes are derived from life, bringing many benefits real.

Turn rice husk into fuel

Mr. Nguyen Van Nghi (Loc Dong, Hoa Thanh commune, Tuy Hoa district, Phu Yen province), the owner of the first prize in the field of Materials, chemicals and environment started his career by hiring 300m2 of warehouse of the agricultural cooperative. Hoa Thanh Tay enterprise in 2009. Then borrowed investment capital to install a technological line to produce rice husk firewood from rice husk waste by himself. Since then, the 'Green Source' rice husk firewood production facility has been established with 30 workers in charge of operating 4 production machines. Every day, the establishment produces 10 tons of rice husk firewood, with the price per ton of 1.2 million dong, the average income per worker is from 3.6 to 5 million dong per month.

According to calculations, 1.5 kg of rice husk firewood is equivalent to 1kg of charcoal, using rice husk firewood instead of wood, charcoal, coal, gas, and kerosene not only save 45-50% of the cost. , but also contribute to minimizing the amount of rice husk released into the environment.

Use coral to treat floor sockets

From the fact that more and more patients suffer from eye socket injury due to traffic accident, author Le Minh Thong and colleagues from Ho Chi Minh City University of Medicine and Pharmacy have 'Study on treatment of fracture of combined eye socket lining fractures with coral preparations taken from Vietnamese waters'.

According to the author, in the past, the treatment for patients with broken eye sockets is often used with an insoluble foam of France and the United States. The advantage of this material is that there are small bone marrow-like holes that make it easier for vascular fibers to grow inside, making the material fixed in place and becoming a component of body tissue. However, this material is very expensive compared to Vietnamese patients. The team has identified the process of making Biosporites biological material to replace bone from the coral of the Vietnamese sea itself. This coral product has been tested and accepted by Ho Chi Minh City Department of Science and Technology.

With the low price advantage, only 12 USD / product while imported materials cost 300 USD, Biosporites can be widely used for patients.

With this solution, the research team was honored to receive the second prize of the 11th Scientific Innovation Contest by VIFOTEC.

Equipment saves 30% of gas

While gas prices rise, gas-saving equipment of KS. Le Tien Thang of the Hung Thang Private Enterprise in Ho Chi Minh City produced it again to help housewives save 30% of fuel. According to KS Thang, the reason the device can help save gas is because it can limit the disadvantages of gas stoves today. Since the fuel used for gas stoves is liquefied Petroleum Gas (LPG), the hydrocarbon molecular chains in LPG are twisted into clusters so the oxygen in the air is difficult to penetrate into LPG. Therefore, LPG is difficult to burn completely on the burner of gas stove, leading to a lot of fuel consumption, while discharging harmful emissions such as CO, NOx, CH .

Gas saving equipment set by KS. Winning invention consists of a set of permanent magnets fitted with polarity to create closed magnetic circuits, creating an internal magnetic field. Thanks to the magnetism of two magnet rods, the hydrocarbon molecular chains in the LPG stream from the tank when passing through the device will be stretched, more evenly distributed, creating a sufficiently wide distance for oxygen to penetrate and create a burning reaction. thoroughly on the burner of the gas stove. Thanks to that, the gas stove burns green and more evenly, increasing heat productivity.

When installing gas-saving equipment, it can be extended to 38 days, instead of 28 days for 12kg gas cylinders. Gas-saving equipment has also been used in Dam Sen Water Park, many restaurants, restaurants and families in Ho Chi Minh City .

During this award, KS was also honored to receive the second prize in the field of mechanics, construction and transportation.
