| titleOfInvention | Urea water supply device to remove impurities and adjust urea concentration |
| abstract | The present invention relates to a device for supplying urea water capable of removing impurities and adjusting the concentration of urea water, comprising: a urea water storage tank 1 that forms an enclosed space so that urea water is injected and urea water is stored therein; When supplying urea water to the vehicle, the urea water in the urea water storage tank 1 is not filled by supplying nitrogen gas to the urea water storage tank 1 as much as the urea water volume of the urea water storage tank 1 is reduced. In the urea water supply device including a nitrogen filler that suppresses the growth of aerobic bacteria in the urea water storage tank (1) by filling an unrecovered space with nitrogen gas, one side or a bottom side of the urea water storage tank (1) The urea water is circulated as external urea water is supplied to the inside according to the pump operation or urea water is circulated so that the urea water is self-circulated according to the pump operation to prevent urea salt from adhering to the wall or bottom of the urea water storage tank (1). With the unit 100 formed, the urea water stagnated in the urea water storage tank of the urea water supply device in the form of a dispenser for supplying urea water is circulated to suppress the formation of urea salt, thereby supplying higher quality urea water As this is possible, it is possible to prevent damage to the vehicle's SCR system, increase exhaust gas removal efficiency, and improve vehicle fuel efficiency. As the urea water is circulated, the adhesion of urea salt inside the urea water storage tank is minimized. The present invention relates to a device for circulating urea water to prevent the occurrence of urea salt, which minimizes unnecessary processes such as washing processes, thereby simplifying maintenance, reducing maintenance costs and maximizing convenience in use. |
