Air dust removal system, air disinfection system, air flow organization system and other units. The main equipment of air purification project consists of induced draft fan, pre-filter, main filter (electrostatic precipitator), ozone sterilization layer, activated carbon filter and negative ion generator. In addition, in order to ensure the humidity and temperature in the air, the dust-free purification project can also increase heating or cooling, constant humidity and other devices.
(1) induced draft fan: generally, multi-stage centrifugal fans are adopted, which can ensure the air volume and air pressure with low noise. When electrostatic dust removal is used, the cross-flow fan can also meet the requirements.
(2) Main filter: remove particles smaller than 1. Choose one of high efficiency filter and electrostatic precipitator. Among them, the proportion of electrostatic precipitator is 90%.
(3) Activated carbon filter: After passing through the main filter and then filtering through the activated carbon column, ozone and acid gas can be removed, and dust, aerosol and steam in the gas can be purified.
(4) Pre-filters, that is, primary filters and intermediate filters. The purpose of dust-free purification project is to remove particles larger than 5 in fresh air and protect subsequent high-performance filtration equipment.
(5) ozone sterilization layer: ozone generated by an ozone generator is used to sterilize the air.
(6) Negative ion generator: Negative ion generator can make particles floating in the air negatively charged. Dust-free purification project is to make these particles easy to be intercepted or precipitated, thus making the air in the workshop cleaner. Therefore, most air purification systems are equipped with negative ion generators to improve air quality.
