The anti-corrosion measures for organic fertilizer production lines mainly include the following aspects:
1. Equipment material selection: key components such as granulator molds, stirring and conveying blades are treated with corrosion-resistant stainless steel to improve corrosion resistance and wear resistance. The inner wall of the fermentation tank adopts acid-alkali anti-corrosion coatings, such as ZS-1034 acid-alkali anti-corrosion coatings, which can withstand the full range of acid and alkali environments with a pH value of 0-14, and effectively resist the penetration corrosion of organic acids, sulfides and other media.
2. Process design optimization: The fermentation tank adopts a closed design to reduce the escape of corrosive gases (such as hydrogen sulfide and ammonia) and reduce corrosion to the equipment. Oxygen is supplied through a forced ventilation system to avoid anaerobic environments and reduce the generation of corrosive gases.
3. Daily maintenance and care: Clean the residual materials inside the organic fertilizer equipment in time to prevent the materials from sticking to the cylinder and reduce corrosion. Regularly add lubricating oil to bearings, gears and other parts to prevent rust; perform anti-rust treatment on the surface of the equipment, such as applying anti-rust paint.
4. Environmental control: Keep the production environment dry to prevent the equipment from getting damp; control the fermentation temperature to reduce the corrosion of the equipment by high temperature.
Take anti-corrosion and anti-seepage measures for sewage treatment tanks, liquid storage tanks, etc. to prevent the leakage of corrosive liquids.
Through the above measures, the organic fertilizer production line can effectively prevent equipment corrosion, extend the service life of the equipment, reduce maintenance costs, and ensure the stable operation of the production line.
