Dust Removal Generation and Properties of Dust in Ginning Mills Composite Fabric Information

1. Generation of dust
Seed cotton, lint or cotton seeds and other materials are mixed with fine dust, soil, dried and broken cotton leaves or short cotton stalks and other debris. During the transportation process, due to friction and collision of machinery and equipment, the above-mentioned substances break, causing part of them to turn into finer powder particles, which spread out from loose parts of transportation, separation and other equipment.
During the production process of ginning, velvet stripping and other equipment, some working parts are not tightly sealed, causing fine dust, short fibers, etc. to overflow with the flow of air and float in the air, causing air pollution. .
2. Classification of dust
According to the nature of dust, it can be divided into:
(1) Organic dust, such as fine cotton leaf powder, short cotton fibers, etc.
(2) Inorganic dust, such as dust, metal powder, etc.
(3) Mixed dust, including organic dust and inorganic dust.
According to the shape of dust:
(1) Plastic dust.
(2) Powder and granular dust.
(3) Fibrous dust.
The dust in the ginning factory is mostly composed of powdery and fibrous dust, mainly fibrous.
3. The hazards of dust
No matter what kind of dust, it is harmful to humans. The degree of harm is not only related to the material properties of the dust, but also related to the linear size of the dust particles.
According to research, dust particles larger than 5 μm can easily adhere to the mucous membranes of respiratory organs, such as the throat, eyes, nasal cavity, etc., causing itching and in serious cases leading to inflammation or ulceration; dust particles smaller than 5 μm, It can directly invade the human lungs and easily cause silicosis.
Dust is also harmful to mechanical equipment. If dust falls into the bearings of machinery and equipment, it will cause poor lubrication and premature wear of the bearings. The motor will have poor heat dissipation due to dust obstruction and reduce efficiency. The dust in the ginning factory contains a lot of organic components. If it sticks and accumulates everywhere, it can easily cause a fire. Therefore, efforts must be made to remove dust.
