In the 21st century, various technologies and achievements have emerged one after another, and technology is developing rapidly. However, the development of the 21st century is far beyond technological development. An increasingly serious and prominent problem is quietly rising: environmental degradation. The deterioration of the environment is not only caused by traditional soil erosion and desertification, but also by ocean pollution, climate change, and El Ni ñ o phenomenon, which have become major issues facing the 21st century. Dust pollution is one of the serious problems. Dust pollution is by no means a trivial matter, it directly threatens people's lives, especially in environments with dust pollution that can cause various cardiovascular and respiratory problems. The continuous increase of disease and incidence rate this year is a typical manifestation of the intensification of dust pollution, which has a great impact on the elderly and children. Moreover, excessive dust can easily breed bacteria and viruses, which is extremely detrimental to one's health. There may also be risks to skin health. However, it is precisely the harmful dust pollution that has not received enough attention and attention from people, and has not been able to take decisive measures to curb the continuous spread and aggravation of dust pollution. Don't think that the severity of dust pollution is inferior to problems such as ozone black holes, land desertification, soil erosion, and water quality pollution. Even if ozone is depleted, land becomes fertile again, water becomes clear and blue, dust pollution can still cause human and animal deaths in various ways, even extinction. It is urgent for humans to re-examine the dust world and find a new, convenient and effective way to control it, in order to turn the beautiful blue planet of Earth into a lifeless and gloomy world like a crescent moon. The following are some specific reports on the sources, hazards, development trends, and prevention of dust pollution: within 8 hours, when the average dust concentration in the workshop is below 1 (milligrams/cubic meter), it is harmful to the human body. When the concentration is above 3 (milligrams/cubic meter), it is more harmful, with a high allowable value of 10 (milligrams/cubic meter). Currently, most woodworking workshops and artificial stone workshops cannot meet this requirement. The sentence is:. Dust does not directly harm people, but it can cause significant harm to organs such as the respiratory tract and eyes. Dust with a particle size greater than 10 microns has a shorter residence time in the air and can be trapped in the respiratory tract during respiration, not entering the alveoli. However, due to the presence of wood tar in wood dust, which is composed of various phenols and hydrocarbons and contains highly carcinogenic substances, over time, some workers may suffer from emphysema and even cancer. Wood powder with a particle size of less than 10 microns can directly enter human lung tissue and precipitate in the alveoli, which may cause chronic fibrosis of lung tissue and even lead to a series of diseases such as pulmonary heart disease and cardiovascular disease. And these inhalable substances can also bring various pollutants or bacteria into the lungs, posing a great threat to human health. If dust bounces or flies into people's eyes, it can cause injury and affect normal operations. In addition, wood dust is also one of the dangerous flammable materials, which can easily cause fires. In addition, suspended dust can increase abnormal wear and tear of production equipment, shorten equipment lifespan, increase maintenance costs, and thus have an undeniable impact on the output and economic benefits of enterprises. To prevent dust pollution fundamentally, we need to take a comprehensive approach, starting from production equipment, selecting reasonable mechanical equipment, and supplemented with dust prevention and removal measures. But under current conditions, the measure is still to choose dust removal equipment. The selection of dust removal equipment should consider the required purification level and the nature of the dust at the operating site. For large and medium-sized wood dust, they can be collected on site in a timely manner, while for various types of fine wood dust with high harm, the traditional method is to use pneumatic dust collection devices or bag vacuum equipment to collect them. It is worth noting that small factories that currently do not have the conditions to install large-scale vacuum equipment can attach single machine vacuum and dust collection devices to the machine tool itself, which can also achieve good results. For safety reasons, operators should wear protective goggles and dust masks to protect their eyes and respiratory organs. Especially for workers operating on machine tools that generate fine wood dust, they should wear large masks to prevent dust damage. According to the Air Pollution Prevention and Control Law, pollution prevention and control measures shall be taken for the discharge of dust, odorous gases, or other gases containing toxic substances into the atmosphere; Emissions of converter gas, calcium carbide gas, yellow phosphorus tail gas from electric furnace method, and hydrocarbon tail gas into the atmosphere must be approved by the local environmental protection administrative department. Therefore, if pollution prevention and control measures are not taken, and dust, odorous gases or other toxic substances are discharged into the atmosphere, or converter gas, calcium carbide gas, electric furnace yellow phosphorus tail gas, and hydrocarbon tail gas are discharged into the atmosphere without approval, the environmental protection administrative department of the local people's government at or above the county level or other departments exercising supervisory power in accordance with the law shall order the cessation of illegal activities, make corrections within a time limit, and may impose a fine of up to 50000 yuan.
