'Engineers are not equal to processing medical waste treatment furnaces

The waste incinerator uses the maximum amount of fuel from the combustion engine's waste oil, reducing the cost of burning each kilogram of garbage to 5,000 dong, becoming the first product in Vietnam to meet national technical standards on emissions. industrial waste incinerator.

Medical waste treatment furnace of "non-qualified engineers"

Mr. Trinh Dinh Nang , residing in Bac Kan City, is called by many "non-degree engineers" . As a child, his family was in a difficult situation, so he only finished Grade 6 and then quit to help his parents earn money. When I grew up, I went to learn mechanical engineering and opened a motorbike repair shop. On that day, the young worker was very passionate about making " exclusive " parts to sell to customers on order.

Life is more difficult, Nang Bon has done many jobs. There was time to go to gold mining, he made his own gold filtering machine from soil and crushed stone to bring high profit, but you do find a way to appropriate, so you get bored. He is also attached to some companies but then decides to open a private property, choose his own path and to be creative.

Workers who finish 6th grade have built a medical waste incinerator with high efficiency, much cheaper than other types of incinerators imported from abroad. He shared that, during a visit to Bac Kan General Hospital, seeing people assembling a system of waste treatment kilns in the UK with a large amount of imports. While the cost to burn and dispose of medical waste is still high, it cannot handle all toxic wastes such as furan gas, dioxin and odor.

" In my mind, I have the idea of ​​designing and manufacturing medical waste incinerators with the criteria of cheap price, superior technology and low operating costs to serve domestic demand ," he said. .

To complete the incinerator, it took him nearly a year. The system consists of 3 parts: burner, incinerator and smoke treatment system. The principle of the system is to use high-tech burners to supply heat, maximizing fuel from waste oil of explosion engines, diesel, Do, Fo . even oil.

The heat of 1,800 degrees Celsius in the incinerator is thoroughly eliminated with the burning capacity of 30-50 kg of waste per hour . Operating parameters of the system are controlled via LCD display screen. The smoke treatment kit ensures that no dioxins and furans are regenerated, the smell is completely burned. The cost is 5,000 VND / kg of burning waste in diesel and 2,000 VND when burning with waste oil. He said the experts all claimed his products were cheaper, lower operating costs than imported ones, at a cost of up to VND20,000 - 40,000 / kg.

Mr. Nang's medical waste incinerator is the first product in Vietnam to meet the national technical standards on industrial waste incinerator emissions (Regulation 30) of the Ministry of Natural Resources and Environment. The product is patented in 2012 and is currently used in some hospitals. The field of application of the blast furnace is also quite extensive, not only in health but also used in the environment and living.

" To sell the market is another story, I have real difficulties and sometimes seem to be unable to continue, " he said. He realized that the commercialization of products is unique, the market is narrow and picky is the biggest difficulty.

In addition to the above invention, he also researched a system of equipment to make clean vermicelli from galangal tubers , not to use toxic chemicals to make powder and to double the capacity of making traditional vermicelli.

He shared that his passion for creativity stems from the desire to make valuable products from ordinary materials. " All research or inventions have no meaning when not valid for practical use to be effective. The inventions of ordinary workers derive from the actual demand during the production process. export, "he said.
