Description

Technical Field

[0001] The invention belongs to the technical field of vehicle urea production, and in particular relates to a vehicle urea production device. Background Art

[0002] At present, the SCR scheme has obvious advantages in the exhaust emission treatment system of National IV diesel vehicles, and automotive urea is a necessary additive for the SCR scheme. Automotive urea is composed of 32.5% high-purity urea and 67.5% deionized water. Engine manufacturers have begun to use SCR technology to meet the requirements of environmental protection departments. The SCR system includes a urea tank (loaded with automotive urea) and an SCR catalytic reaction tank. The operation process of the SCR system is: when nitrogen oxides are found in the exhaust pipe, the urea tank automatically sprays out automotive urea, and automotive urea and nitrogen oxides undergo oxidation-reduction reactions in the SCR catalytic reaction tank to generate pollution-free nitrogen and water vapor for discharge. If automotive urea is not loaded, or the purity is insufficient, or the quality is inferior, the vehicle engine will automatically slow down. At the same time, inferior automotive urea will contaminate the catalyst in the SCR catalytic reaction tank, causing serious consequences.

[0003] Publication No. CN106582338A discloses a process for producing automotive urea, comprising the following steps: step 1. unloading: pouring bagged solid urea into a mixing tank; step 2. water injection: injecting ultrapure water into the mixing tank to mix with the solid urea to form a urea solution; wherein only a single stirring rod is used for stirring when the solid urea and the ultrapure water are mixed and stirred, which not only has low stirring and mixing efficiency, but also easily leads to insufficient mixing.
