1970 - 01 - 01 washing powder ( Washing powder, car environmental urea) The scientific name is diesel exhaust treatment fluid. Used in diesel engines. It is a kind of SCR technology must be used in consumables, used to reduce nox in diesel exhaust pollution of the liquid. Its composition is 32. High purity of 5% urea, and 67. 5% of deionized water. 1, water system, process raw water & rarr; The original water tank & rarr; Booster pump & rarr; Sand filter & rarr; Activated carbon filter & rarr; Scale inhibitor dosing & rarr; 5μ Precision filter & rarr; Level of high-pressure pump & rarr; Level 1 film processing system & rarr; Level of RO water tank & rarr; The secondary high pressure pump & rarr; The secondary membrane processing system & rarr; The secondary RO water tank & rarr; RO water tank & rarr; Pure water pump & rarr; Agitation tank 2, washing powder equipment production process water & rarr; Pretreatment & rarr; Level 1 reverse osmosis & rarr; The secondary reverse osmosis & rarr; Feeding machine & rarr; Stir in homogeneous system & rarr; Ion purification equipment & rarr; Purifying & rarr; Decolorizing system & rarr; At the beginning of filtering system & rarr; Filling at the beginning of this production line consists of premixed system, filtration system, homogeneous systems, decolorization and purification system, etc, the operation mode for the current is the advanced and mature domestic washing powder production process, has entered a stage of large-scale industrial production. This kind of production mode and concept, in sinopec, can LanSu and yuchai, hubei wei automobile exhaust and other companies have production operation; A) Filtering and decoloring system: at the beginning of removal of suspended solids in urea and other impurities floating, ensure process after the unaffected. Decolorizing system is made of high quality activated carbon adsorption bleaching and remove other organic impurities in urea, urea solution more clear. 2) Fine filtration system: prevent decolorizing activated carbon particles in the system to enter after processing, affect the quality of the product after. 3) Purification system: adopting multi-stage purification tower, remove all kinds of ions, biuret urea solution, the impurities such as phosphoric acid root, ensure that the product conforms to the specification SAE - China automotive engineering society ChinaJ2901-2013 'technical specification for detergent solution standard requirements. 4) Microfiltration system: interception process piping, storage tank, power equipment, may produce some of the residual impurities are not visible to the naked eye, ensure the quality of the finished product is stable and reliable. 5) Reduction regeneration system: purification tower in the process step by step in the process of failure, reaches a certain cycle reduction regeneration process, the reduction treatment on the purification of repeated use, can fully meet the requirements of the original production technology. Each regeneration cycle produces in the process of wastewater, the wastewater contains no other heavy metals, mainly is the PH value is not in conformity with the requirements. After adjusting and can achieve environmental emissions standards. The previous: washing powder equipment manufacturers to guide washing powder production process
