Yantai Yi and car urea equipment Introduction of car urea equipment by the pre-mixing system, heat transfer system, primary filtration system, homogenization system, decolorization system, purification system, regeneration system, etc., this mode of operation for the current is the domestic advanced and mature automotive urea processing equipment has entered the stage of large-scale industrial production.
I) automotive urea equipment pre-mixing system: the use of homogeneous system, to remove some of the aldehydes in the raw liquid, and play a homogenizing effect.
II) automotive urea equipment heat transfer system (optional): adjusted to the process requirements of the temperature. Bagged granular urea needs to be warmed up so that the urea particles easier to dissolve (Party A provides steam).
Three) automotive urea equipment primary filtration and decolorization system: to remove suspended matter and other floating impurities in the urea, to ensure that the latter process is not affected. Decolorization system adopts high-quality activated carbon for adsorption and decolorization, removing other organic impurities in urea and making the urea solution clearer.
D) Car urea equipment fine filtration system: to prevent the activated carbon particles in the decolorization system from entering the post-treatment process, affecting the quality of the post-process products.
V) purification system of automotive urea equipment: adopting multi-stage purification tower to remove various ions, diureas, phosphates and other impurities in the urea solution, to ensure that the product meets the requirements of Chinese Society of Automotive Engineers' Technical Specification GB 29518-2013 Diesel Engine Nitrogen Oxide Reducing Agent Urea Aqueous Solution (AUS 32) standard.
VI) Microfiltration system of automotive urea equipment: intercepting some residual impurities that are not visible to the naked eye that may be generated by pipelines, storage tanks, power equipment, etc. in the process of production, to ensure the quality of the finished product is stable and reliable.
seven) automotive urea equipment reduction and regeneration system: purification tower in the process of production gradually failed to reach a certain period of time need to restore the regeneration process, the process takes 6-8 hours. By reducing the regeneration of the purification tower reuse, can fully meet the requirements of the original production process. Each regeneration cycle will produce 2 tons of waste water, the waste water does not contain other heavy metals, mainly PH value does not meet the requirements. After neutralization and adjustment can meet the environmental discharge standards.
Eight) Wastewater treatment system: the waste liquid generated in the process of regeneration of reduction and treatment, to meet the discharge standards.
