Description:FILTRATION SYSTEM FOR UREA DOSING AND A METHOD THEREOF
FIELD OF THE DISCLOSURE
[0001] This invention generally relates to a field of urea dosing in exhaust gases emitted from a vehicle, in particular relates to a filtration system for urea dosing.

BACKGROUND
[0002] A urea dosing system is a vital component in modern after-treatment systems designed to reduce nitrogen oxides (NOx) emissions in vehicles and industrial applications. This system facilitates the controlled injection of pressurized urea into the mixing chamber of the after-treatment system, where the pressurized reacts with exhaust gases. The urea is typically an aqueous solution, commonly known as Diesel Exhaust Fluid (DEF), which undergoes thermolysis and hydrolysis to produce ammonia (NH₃). The ammonia then reacts with NOx in the Selective Catalytic Reduction (SCR) process, converting harmful NOx emissions into harmless nitrogen (N₂) and water (H₂O).
[0003] The system is compact and complex, designed to maintain precise dosing and optimal , Claims:We Claim:
1. A filtration system (100) for urea dosing comprising a reciprocating pump configured to provide a urea solution to a selective catalytic reduction (SCR) mixing tube of a vehicle, a header (102) having a suction inlet pipe (104) coupled to the reciprocating pump for directing the urea solution from a first end (112) to a second end (114) of the suction inlet pipe (104), a urea level and quality sensor (ULQS) (116) coupled to the second end (114) of the suction inlet pipe (104) and an air vent pipe (110) coupled to the ULQS (116), characterised in that:
a three-dimensional (3-D) filter (118) housed within the ULQS (116) and coupled to the second end (114) of the suction inlet pipe (104), wherein the 3-D filter (118) is configured to filter the urea solution received via the second end (114) of the suction inlet pipe (104); and
a vent plug (202) integrated at an opening of the air vent pipe (110), wherein the vent plug (202) is configured to seal the opening and block entry of ambient air inside th
