Environmental protection industry - solid and liquid waste rotary kiln treatment system Primary fan

The primary fan ( primary oxygen fan) is a key device for controlling combustion efficiency. In the solid and liquid waste rotary kiln treatment system, its installation location is as follows:

Oxygen supply port in the main combustion area of the rotary kiln

The primary fan is usually installed near the rotary kiln head burner, supplying combustion air to the main combustion zone in the kiln through high-pressure air ducts to ensure sufficient contact between the waste and oxygen. This location must meet the following requirements:
1. The air duct and burner are coaxially arranged, and the wind speed is 15-35m/s to penetrate the waste layer.
2. The fan housing should be ≥2m away from the high-temperature area of the kiln to avoid the influence of heat radiation.

Liquid waste nozzle auxiliary oxygen supply
If the system processes high-viscosity waste liquid, the primary fan may be integrated into the waste liquid spray gun system to improve combustion efficiency by atomising air. In this case, the fan must meet the following requirements:
1. Install on the same side as the nozzle, wind pressure 5-20kPa
2. Explosion-proof design to deal with the risk of organic solvent volatilisation

Installation specification requirements

Safety distance: The distance between the fan and high-temperature equipment should be ≥ 2m to avoid the influence of heat radiation.

Maintenance channel: Reserve ≥0.8m maintenance space to facilitate fan disassembly and maintenance, and seal replacement.

Anti-seismic measures: The foundation needs to be treated with shock absorption, and the vibration value should be ≤4.5mm/s.
