Vehicle urea liquid equipment is composed of pre mixing system, heat exchange system, primary filtration system, homogenization system, decolorization system, purification system, regeneration system, etc. this operation mode is the domestic advanced and mature vehicle urea production equipment, which has entered the stage of large-scale industrial production.
1） Premixing system of automobile urea liquid production equipment: the homogenization system is used to remove part of aldehydes in the raw material liquid and play the role of homogenization.
2） Heat exchange system of automobile urea liquid equipment (optional): adjust to the required process temperature. The bagged granular urea needs to be heated to make the urea granules more soluble (Party A provides steam).
3） Primary filtration and decolorization system of vehicle urea solution production equipment: remove suspended solids and other floating impurities in urea to ensure that the next process will not be affected. The decolorization system uses high-quality activated carbon for adsorption and decolorization to remove other organic impurities in urea and make the urea solution clearer.
4） Automobile urea solution production equipment fine filtration system: to prevent the activated carbon particles in the decolorization system from entering the subsequent treatment process and affecting the quality of the subsequent products.
五）车用尿素提纯设备提纯系统：采用多级提纯塔方式，去除尿素溶液中的各种离子、缩二脲、磷酸根等杂质，确保产品符合中国汽车工程学会技术规范GB 29518-2013 柴油发动机氮氧化物还原剂 尿素水溶液(AUS32)标准要求。
5） Purification system of vehicle urea purification equipment: multi stage purification tower is adopted to remove various ions, biuret, phosphate and other impurities in urea solution, so as to ensure that the product meets the requirements of technical specification of China Society of automotive engineering GB 29518-2013 for nitrogen oxide reducing agent urea aqueous solution (aus32) of diesel engine.
6） Microfiltration system of automobile urea purification equipment: intercept some invisible residual impurities in the pipeline, storage tank and power equipment in the production process, so as to ensure the stable and reliable quality of finished products.
7） Reduction and regeneration system of vehicle urea production equipment: the purification tower gradually fails in the process of production, and it needs to be reduced and regenerated when it reaches a certain period, and the process takes 6-8 hours. The purification tower treated by reduction and regeneration can be reused, which can completely meet the requirements of the original production process. Each regeneration cycle will produce 2 tons of wastewater, which does not contain other heavy metals, mainly because the pH value does not meet the requirements. After neutralization adjustment, it can reach the environmental protection emission standard.
