Abstract
An exemplary embodiment of the present invention provides a urea water manufacturing device which can reduce the time for producing urea water by forming a vibrating atmosphere using an ultrasonic wave generator when stirring urea and pure water supplied inside a stirring tank, and can produce urea water with high purity by real-time feedback control of specific gravity of urea water, and a method thereof. The urea water manufacturing device according to an exemplary embodiment of the present invention includes a pure water supply unit, a urea supply unit, a stirring unit, a specific gravity detection unit, a control unit, and a urea water discharge unit.
Claims11
A urea water manufacturing device, which comprises:
- a pure water supply unit, which comprises a pure water supply line connected with a stirring tank and that supplies pure water into the stirring tank;
- a urea supply unit, which comprises a urea supply line connected with the stirring tank and that supplies urea into the stirring tank;
- and
- a stirring unit, in which the pure water and the urea supplied into the stirring tank are stirred in a predetermined stirring vibration atmosphere;
- wherein the stirring unit includes:
- a stirring operation unit configured to generates rotational power of the stirring unit;
- and
- a stirring vibration unit configured to form the stirring vibration atmosphere for stirring the pure water and the urea within the stirring unit,
- the stirring vibration unit includes ultrasonic wave generators configured to generate vibration waves, and
- wherein a first vibration wave frequency generated by the ultrasonic wave generators during manufacturing the urea water is lower than a second vibration wave frequency generated by the ultrasonic wave generators during self-cleaning.
