Analysis of environmental measures in NPK blending fertilizer production lines
Environmental concerns in fertilizer production are receiving growing attention. NPK blending fertilizer production lines incorporate multiple eco-friendly technologies to effectively reduce dust, exhaust gases, and noise pollution, enabling cleaner production.
1.Dust Control
Enclosed conveying systems: Use tubular chain conveyors or sealed belt conveyors to minimize material dust.
Wet dust suppression: Spray water mist at dust-prone points to reduce airborne particle concentration.
2.Exhaust Gas Treatment
Tail gas absorption towers: Treat ammonia and dust from granulation and drying processes using alkaline solution sprays or activated carbon adsorption.
Biological deodorization (applicable to organic-inorganic compound fertilizers): Use microorganisms to break down odorous gases and reduce foul odors.
3.Noise Reduction
Vibration and noise damping: Install shock-absorbing pads under high-noise equipment like fertilizer crushers and mixers to lower mechanical noise.
Low-noise motors: Prioritize variable-frequency motors or silent transmission equipment to reduce noise at the source.
4.Waste Recycling and Resource Recovery
Screening return system: Re-granulate non-compliant particles after crushing to minimize raw material waste.
Wastewater recycling: Reuse cooled and sprayed water after sedimentation and filtration for near-zero discharge.
Through dust management, exhaust purification, noise control, and waste recycling, NPK blending fertilizer production lines achieve green and low-carbon production.
