Description

Technical Field

[0001] The utility model relates to the technical field of vehicle urea production, in particular to a filtering device used for vehicle urea production. Background Art

[0002] In order for heavy trucks, buses and other diesel vehicles to meet the National IV emission standards, they must use a suitable SCR system for exhaust gas treatment, and this system must use urea solution to treat nitrogen oxides in the exhaust gas. Therefore, automotive urea solution has become a must-have product for heavy trucks and buses to meet the National IV emission standards. Automotive urea refers to a urea aqueous solution with a urea concentration of 32.5% and a solvent of ultrapure water. The raw materials are special raw materials for automotive urea and ultrapure water.

[0003] At present, when preparing automotive urea solution, it is necessary to dissolve the special raw materials for automotive urea into ultrapure water, and then mix and stir to obtain the solution. However, since the special raw materials for automotive urea contain certain impurities, the impurities are integrated into the automotive urea solution after mixing, resulting in low cleanliness of the automotive urea solution. The existing impurity removal method mostly uses a single-layer filtration method for impurity removal. This impurity removal method not only affects the flow rate of the solution when the filter plate is blocked, but also affects the filtration degree of impurities. Utility Model Content
