AI Technical Summary
Existing dust removal and fresh air equipment is expensive, has high filter replacement costs, and is inconvenient to maintain. It is difficult to meet the requirements of the exhaust gas treatment system in light industrial and food processing workshops. Existing equipment cannot effectively improve the working environment. Existing technology cannot improve the working environment. Existing equipment has high maintenance costs. Existing technology cannot effectively solve the problem of high maintenance costs. Existing equipment cannot effectively solve the problem of high maintenance costs. Existing equipment cannot effectively improve the working environment.
The system employs a collection duct, a main fan, and an air supply and dust collection module, including a cyclone spray tower, an air supply fan, and filter components. Through the cyclone spray tower's swirl vanes, spray channels, spray pipes, and adsorption packing layer, it achieves dust removal and cooling of the exhaust gas. The adsorption packing layer is also flushed through a top wash pipe to prevent clogging.
It achieves excellent dust removal and cooling effects, reduces maintenance frequency and costs, provides fresh air, and improves the cleanliness of the working environment and the flexibility of the equipment.
