Equipment for producing automotive urea aqueous solution

Composition Description of Automotive Urea Equipment

Our company's automotive urea equipment is mainly composed of ultra pure ureaDeionized water equipmentComposed of post filtration and purification equipment. Ultra pureDeionized water equipmentThe main treatment method used is ion exchange resin (after cation bed, anion bed, and mixed bed exchange), which has the advantages of strong deionization ability and high purity, but cannot remove non electric substances such as organic matter; At present, suitable methods such as reverse osmosis or electro deionization are mainly used in the process. Reverse osmosis is used for initial desalination, and then electro deionization is used instead of mixed bed as the precision treatment equipment. After circulating and filtering through atomic level ion exchange columns, the effluent conductivity can reach 17-18 megaohms. Post filtration and purification equipment: Traditional automotive urea solution typically requires a post filtration accuracy of 1 micron or 0.2 microns. Currently, in China VI, a filtration and purification accuracy of 10 nanometers is required.

What is automotive urea solution? What is its function?

Automotive urea solution is called Adblue in Europe, DEF (Diesel Exhaust Fluid) in North America, and automotive urea solution or "urea solution" in China.

The most basic function of urea solution for cars is to convert nitrogen oxides in car exhaust into harmless nitrogen and water, and the use of urea solution can reduce fuel consumption, increase power, save energy and protect the environment. Therefore, the country has mandated the implementation of the National Five Six Policy. The current national standard for urea concentration in China VI is 32.5% (± 0.7%), which is composed of 32.5% high-purity urea and 67.5% ultrapure water (deionized water) according to GB29518-2013 standard.

How to store automotive urea solution?
The ideal storage temperature for long-term preservation of automotive urea solution is between -5 ℃ and 25 ℃, and it should be stored in a sealed container to avoid contamination; Avoid direct sunlight. If the above requirements are met, the automotive urea solution can be stored for at least 18 months. For every 5 ℃ increase in ambient temperature, the lifespan will be reduced by 6 months.

whyDo I need to use urea equipment for my car?
The National VI standard for automotive urea solution is composed of 32.5% high-purity urea and 67.5% ultra pure deionized water, and has strict requirements for the content of urea, insoluble substances, iron, sulfides, chlorides, etc. Any poor quality urea, as well as improper mixing and storage with water (using tap water), can cause blockage or even damage to the urea pump and nozzle, and even lead to crystal blockage of the SCR catalyst. In severe cases, it can cause irreversible permanent damage to the components of the SCR post-treatment system.
