Description

Haze filtration system

The invention relates to a smog filtration system, in particular to a smog filtration system with water resource recycling and green wall function.

Smog, as the name implies, is a combination of fog and sputum. From a meteorological point of view, fog is an atmospheric phenomenon consisting of extremely fine and dense water droplets suspended in the air near the ground. A crucible is a pollutant formed by solid or liquid particles suspended in the air like dust, generally referred to as particulate matter (PM). According to the size of the particle size, it can be divided into suspended particles (particle size less than or equal to 10 microns-μm; PM10) and fine aerosols (particle size less than or equal to 2.5 microns-μm; PM2.5), which is filled with air that we normally breathe. PM10 and PM2.5, in other words, PM10 and PM2.5 will enter our body as we breathe.

Within a few hours, PM10 will fall due to gravity, and PM10, which enters the body with breathing, can usually be blocked by the cilia and throat mucus in the human respiratory tract. However, PM2.5 can be suspended in the air for a long time or float with the airflow, and it is easy to adsorb toxic substances such as sulfur dioxide until it adheres to the ground. PM2.5 can be directly inhaled into the respiratory tract, into the lungs or into the alveoli, and can enter the bloodstream to the body, which is the main cause of asthma and chronic bronchitis. Due to the toxicity of PM2.5 itself or carrying toxic substances, it is more harmful to human health than ordinary aerosols (PM10). Therefore, PM2.5 has become an important index to monitor the degree of air pollution.

The main sources of PM2.5 include: 1. Natural sources: such as volcanic eruptions, forest fires, etc. 2. Integrity: For example, in thermal power plants, petrochemical plants, and incomplete combustion of general plants, including heavy metals, dioxin, polycyclic aromatic hydrocarbons, and organic carbon that is incompletely burned by diesel vehicles. 3. Derivatives: Sulfur oxides or nitrogen oxides and organic carbon compounds emitted from factories, steam locomotives and petrochemical industries are exposed to toxic fine aerosols such as sulfates, nitrates and organic carbon in the form of sunshine, forming secondary pollution. Things.

According to a regional study, construction and road dust (37%) were the largest sources of primary PM2.5 in urban areas, followed by industry (23%) and motor vehicles (23%); Excavation, demolition, handling and loading, and the dust generated during the physical operation stage such as earth and stone on the construction site, the black smoke emitted during the operation of the engine of the construction machine, or the paint, paint and adhesive used in the construction and decoration are PM2. 5 Sources of precursor emissions often cause deterioration of nearby air quality. The sulfur oxides in the derivative PM2.5 precursors are mainly industrial emissions (88%), while the nitrogen oxides are the highest in motor vehicles (50%) and industrial emissions (41%). Therefore, how to reduce PM2.5 and PM10 in the air and improve air quality has become one of the most important environmental issues in the world.
