Nguyen Van Bon and his machine

Bon began thinking of creating a smoke consumer after hearing from a friend who complained about an imported factory smoke-purification product that was too costly. 

Bon then decided to create a machine which can treat smoke at factories. 

Environmental pollution has become a burning issue in Vietnam. Many enterprises have ignored regulations and discharged untreated waste into the environment. 

Bon believed that a made-in-Vietnam machine with reasonable price would help encourage manufacturers improve waste quality, thus reducing pollution.

Bon began thinking of creating a smoke consumer after hearing from a friend who complained about an imported factory smoke-purification product that was too costly. 

Bon, noting that CRT TV screen can absorb dust and strands of hair, decided to use the principle of electrostatic field to suck smoke into pipes.

The machine has two major parts, a circuit to create a high voltage electrostatic field (tens of thousands of volts) and a smoke-absorbing pipe with two insulated electrodes. 

Smoke particles thicken into solid substances and attach to the pipe wall. After a certain time, users have to clean it.

After a period of working on the principle of electrostatic field, Bon created and tested the machine. 

“When I first tested the equipment at my house, the thick smoke came out of the house and worried neighbors. I had to explain to them that I was carrying out an experiment,” Bon said.

The machine absorbs dust and some odors.  “I don’t have specialized tool to examine if the machine can fully treat smoke,” Bon said.

The young engineer plans to upgrade the equipment so that it can be used to absorb smoke at factories. He also wants to downsize the machine so that it can be used for means of transport such as trucks and motorbikes.

Regarding the price, Bon believes that the machine, once put into commercial development, will be much cheaper compared with imports.
