Description
Technical Field
The utility model belongs to the technical field of the liquid level sensing and specifically relates to a urea liquid level quality sensor based on 3D filter screen.
Background
With the gradual implementation of the emission limit standards of heavy vehicle tail gas pollutants in the fifth and sixth stages in China, the requirement on the limit of emission NOx is increasingly strict, and a Selective Catalytic Reduction (SCR) route is also gradually a preferred scheme of various host plants, engine plants and aftertreatment suppliers. The SCR system works on the principle that under the action of a catalyst, a reducing agent NH3 selectively reduces NO and NO2 in engine exhaust to N2 at 290 ℃ and 400 ℃, so that the emission of NOx is reduced. The quality of urea used as a reducing agent in an SCR system directly affects the exhaust emission, and is more and more emphasized by people. At present, urea manufacturers in China are various, the urea quality is different, urea filling equipment is not popularized yet, the phenomenon of manual urea filling happens occasionally, and various impurities are easy to enter a urea box body in the urea filling link to influence the urea quality, so that the phenomena of over-standard emission, catalyst failure and the like are caused.
