Problems solved by technology
However, the general filtration and purification process is relatively simple, and the filtration accuracy is not high. It cannot effectively remove particles, colloids, bacteria, heat sources, and high-molecular organic substances in the water, thereby reducing the quality of urea solution for vehicles. In addition, there is waste of water resources in the filtration process. Serious, low filtration efficiency problem

Description
technical field [0001] The invention belongs to the technical field of urea solution processing, and in particular relates to a nanoscale filter device and process for high-precision production of urea solution for vehicles. Background technique [0002] The urea solution for vehicles refers to the urea aqueous solution with a urea concentration of 32.5% and ultrapure water as a solvent, and the raw materials are special raw materials for urea for vehicles and ultrapure water. Urea for vehicles is an essential product for heavy-duty diesel vehicles to meet the National IV emission standards. It mainly plays the role of purifying exhaust gas in vehicles, and can react with nitrogen oxides in exhaust gas to reduce nitrogen oxide emissions. Specifically, the production of urea for vehicles mainly includes three stages: urea purification, water treatment, and solution preparation. The main process involved in the entire production process is purification, and the production barr...
