1. Dust removal efficiency is high, it can capture dust above 0.3nm, and make the dust-containing gas to 15mg / m3 or below.
2. The auxiliary equipment is less, the investment is less, and the technical requirements are not as high as those of the electrostatic precipitator.
3． It can capture the dust that is difficult to recover by electrostatic precipitator; and it can collect compounds such as nitrate and sulfide to a certain extent.
4． It has good adaptability to load changes, and is particularly suitable for capturing fine and dry dust. The collected dry dust is easy to handle and recycle.
5. Bag dust collectors are safer when collecting dusty gases that contain explosion hazards or sparks.
Danger of dust
What is productive dust? Generally speaking, solid particles are produced in the production process and can float in the air in the production environment for a long time. The harm of productive dust to the human body is multi-faceted, but the most prominent harm is manifested in the lungs. Due to the different nature and chemical composition of the dust, the harm to the lungs varies greatly. According to the performance after the damage, the dust-induced lungs There are three types of diseases.
The first is pneumoconiosis. This is one of the major occupational diseases. China has been classified as a statutory occupational disease category. This disease is caused by inhalation of higher concentrations of productive dust for a long period of time, causing systemic diseases with lung fibrosis as the main feature. Because there are many types of pneumoconiosis, there are many types of pneumoconiosis, including silicosis, asbestos lung, talc lung, mica lung, coal lung, coal silicosis, and carbon pneumoconiosis.
The second type is pulmonary dust deposition, which is caused by inhalation of some metallic dust or other dust and causes the dust to deposit in the lung tissue, thereby presenting a foreign body reaction, which is less harmful than pneumoconiosis.
The third is dust-induced lung disease reactions and allergic diseases. Such diseases are mainly caused by organic dust, such as cotton dust, hemp dust, fur dust, wood dust and so on.
