Title:
HIGH-PRESSURE UREA SOLUTION PRESSURE-REDUCING AND ENERGY-SAVING DEVICE FOR UREA DEVICE AND PROCESS METHOD
Document Type and Number:
WIPO Patent Application WO/2024/040866
Kind Code:
A1
Abstract:
A high-pressure urea solution pressure-reducing and energy-saving device for a urea device, comprising a hydraulic turbine (1), a liquid level adjustment valve (2), a power device (3) driven by the hydraulic turbine (1), and a manual remote control adjustment valve (4). A third solution outlet (4.2) of the manual remote control adjustment valve (4) is connected to a first solution inlet (1.1) of the hydraulic turbine (1); one path of a high-pressure urea solution is connected to a second solution inlet (2.1) of the liquid level adjustment valve (2), and the other path is connected to a third solution inlet (4.1) of the manual remote control adjustment valve (4); and a first gas-liquid outlet (1.2) of the hydraulic turbine (1) and a second gas-liquid outlet (2.2) of the liquid level adjustment valve (2) are both linked to medium-pressure and low-pressure procedures. Further disclosed is a process method for a high-pressure urea solution pressure-reducing and energy-saving device for a urea device. A large amount of pressure energy lost on the liquid level adjustment valve in the pressure reduction process can be recycled by the hydraulic turbine driving the power device, such that the power consumption of the urea device is greatly reduced; and if the hydraulic turbine needs to be shut down for maintenance, all urea solutions are adjusted by means of the liquid level adjustment valve, and the maintenance is easy.
