Customizable Water Film Dust Collector For Fertilizer Production

Product Overview

Water Curtain Dust Removal Tower is a wet dust removal equipment that uses a water curtain (water curtain) or a spray system to capture, adsorb, and remove dust, smoke, and harmful gases in industrial waste gas. Its core principle is to capture pollutants by water droplets or water films through gas-liquid contact, thereby achieving the purpose of purifying waste gas.
 
Features

1. Specialized in treating NPK compound fertilizer dust, organic fertilizer fermentation tail gas, ammonia (NH₃) and other fertilizer production-specific pollutants
2. The dust removal efficiency of 5μm and above can reach 90%~98%. Anti-scaling nozzle design, suitable for high humidity and high viscosity fertilizer dust working conditions.
3. Low cost and high return
More moisture-resistant than bag dust removal (solves the problem of fertilizer hygroscopicity), saves 40% of investment compared to electrostatic dust removal, and is simple to maintain.
4. Environmentally compliant, meeting the emission standards of atmospheric pollutants.

Working Principle
1. Exhaust gas entry: Dust-containing gas enters the dust removal tower from the bottom or side of the tower body.
2. Water curtain/spray washing:
Water curtain layer: Multiple layers of water curtains or spray devices are set in the tower to form a water curtain barrier.
Atomized water droplets: High-pressure nozzles atomize water into fine droplets to increase the contact area with dust.
3. Gas-liquid mass transfer: Dust particles collide and adsorb with water droplets and settle with the water flow.
4. Gas-liquid separation: The purified gas is discharged after the entrained water mist is removed by a demister (such as a baffle, cyclone separation).
5. Wastewater discharge: Dust-containing wastewater is recycled after sedimentation or discharged after treatment.
 
Applications
Our baghouse dust collectors are ideal for various applications in fertilizer production, including:
Grinding and Milling: Capturing dust from size reduction processes.
Mixing and Blending: Controlling dust generated during the mixing of different fertilizer ingredients.
Granulation: Removing dust from the granulation process.
Drying and Cooling: Filtering dust from dryers and coolers.
Screening and Classification: Capturing dust from screening operations.
Packaging and Bagging: Controlling dust during the filling and sealing of fertilizer bags.
 
 
Product Parameters

Daily maintenance
1. Inspection of circulating water system
Water level monitoring: Ensure that the water level in the water tank is within the marked range (fertilizer dust is easy to absorb water, so water needs to be replenished in time).
Water quality observation: Check the turbidity of circulating water. If there are too many suspended solids (such as NPK dissolved matter), immediately start the sedimentation tank to discharge mud.
pH value test: Keep pH ≤ 6 (acidic environment) when handling ammonia, and use test paper or online instrument to test daily.
2. Inspection of spray system
Nozzle patency: Manually clean the blocked nozzle (fertilizer sticky dust is easy to block, it is recommended to use a spiral nozzle with an aperture of ≤ 5mm).
Water pressure stability: The pressure gauge reading should be maintained at 0.3~0.6MPa. If the fluctuation is too large, check the water pump or pipeline leakage.
3. Fan and pipeline
Abnormal sound monitoring: Abnormal noise from the bearing may indicate that fertilizer dust has entered the fan, and it needs to be stopped for cleaning.
Duct dust accumulation inspection: Knock on the horizontal pipeline, and the muffled sound indicates dust accumulation, and the dust cleaning port needs to be opened (fertilizer dust accumulation is easy to cause fire)
