Five Major Environmental Pollutants from Diesel Generator Exhaust

Globally, the situation of environmental pollution remains grim. Problems such as soil pollution, smog, black and odorous urban river water, garbage - surrounded cities, plastic waste, and rural environmental pollution are prominent. The task of pollution control is arduous. The call for the rapid, continuous, and healthy development of the environmental protection industry and the fight against pollution are crucial tasks for humanity.

However, ignorance and greed have left terrible consequences. All these remind us that environmental protection is extremely urgent! The well - known environmental pollution incidents around the world have sounded the alarm for us. For example, in the London Smog Incident in the UK, many people felt discomfort such as chest tightness and suffocation. According to official UK statistics, more than 5,000 people died during the 5 - day period of the heavy fog, and over 8,000 people died in the two months after the fog dissipated. How terrifying it is!

Compared with nature, humans are always naive and childish. Nature is always the wise victor. It is impossible for humans to fully uncover the mysteries of nature. Humans are just a tiny part of nature. If nature is destroyed, humans will naturally cease to exist. Everyone is responsible for protecting the environment.

The environmental pollution caused by diesel generator sets mainly includes two aspects: noise pollution and exhaust emission pollution. This article mainly analyzes five types of environmental pollution caused by diesel generator exhaust to help everyone with environmental protection.

1.Oxidation: It occurs when the sensitive atmospheric balance is disrupted by excessive HC and NOX. This affects the photosynthesis and respiration of plants, limiting their growth.

2.Acidification: Diesel engine exhaust mainly emits NOX, which can react with water to form nitric acid. In addition, SO₂ can react with water to form sulfuric acid. Both are strong acids that can damage plant growth. NO accounts for about 90%, and NO₂ is only a small part. NO is colorless, odorless, and has relatively low toxicity, but at high concentrations, it can cause paralysis and spasms of the central nervous system. Moreover, when NO is discharged into the atmosphere, it will gradually be oxidized to NO₂. NO₂ is a pungent - smelling, highly toxic (about 5 times more toxic than NO) reddish - brown gas that can damage the human respiratory tract and lungs, and can cause emphysema in severe cases. When the concentration reaches above 100×10⁻⁶ (by volume), it can pose an immediate threat to life.

3.Photochemical smog: In densely populated areas, it forms when large amounts of HC and NOX are exposed to sunlight. The smog contains many pollutants and shows the brown color of NO₂. The nitrogen oxides and hydrocarbons in the smog can affect the respiratory system, increase susceptibility to infections, and especially cause respiratory disorders.

4.Particulate matter: Particulate matter in the air is a result of diesel engine exhaust emissions. Particulate matter consists of very small carbon nuclei (<10um), on which hydrocarbons can deposit and condense, carrying mutagenic and pathogenic hydrocarbons into the lungs.

5.Greenhouse effect: Today, the "greenhouse effect" represents the most widespread environmental threat. There is sufficient evidence to prove the link between "global warming" and the increase in carbon dioxide in the atmosphere. Carbon dioxide mainly comes from the combustion of fossil fuels.

The Earth has been the home where humans have survived since ancient times. There are many resources for our survival in this home. "Water can carry a boat and also capsize it." We must understand the importance of environmental protection. Theoretically, the formation of NOx emissions from diesel generator exhaust cannot be completely avoided, but it can be restricted by controlling the maximum temperature of the combustion process and the residence time of oxygen - rich air at high temperatures.

Dingbo Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to [email protected] we will pay highly attention on your question.
