Ultra pure water equipment for automotive urea

1、 Equipment Introduction
Automotive urea is a necessary product for heavy-duty trucks, buses, and other diesel vehicles to meet the National IV emission standards. Automotive urea is composed of32.5%High purity urea and67.5%Composed of deionized water. That is to say, high-purity urea is dissolved in high-purity water to form a solution. Why is it necessary to useUltra pure water equipmentUltra pure water produced as a dissolving solution?What are the consequences of using tap water as a solution?If the purity of the urea solution used in vehicles is insufficient or the quality is fake, the vehicle engine will automatically slow down, and at the same time, it will polluteSCRThe catalyst in the catalytic reaction tank can cause serious consequences. So, the production of automotive urea requires the use of first grade ultrapure water(Electrical resistivity ≥18MΩ.cm).
grow luxuriantlyThe foundation of environmental protection in meeting user water standardsOn the basis of this, the water tanks in the equipment system are equipped with liquid level control systems, the water pumps are equipped with pressure protection devices, online water quality detection and control instruments, and electrical systems are usedPLCProgrammable controllers truly achieve unmanned operation, while adopting a unified method of recommendation and customer requirements in process material selection, making the equipment more cost-effective and reliable compared to other similar products.

4、 Design Features

1. The system adopts fully automatic control(Manual control can also be used, and automatic backwashing and regeneration programs can be set during system operation;

2. All unit wiring is completed uniformly in the factory, reducing installation and debugging time;

3. The first and second stage reverse osmosis systems are equipped with reflux pipelines, and the reverse osmosis equipment is equipped with chemical cleaning devices;

4. Pipelines are generally usedUPVCtexture of material;

5. Integrated control system and integrated instrument system, etc., facilitate operation and management;

6. ROfilmRegular cleaning Equipped with startup and scheduled cleaningROMembrane function, extendedROMembrane service life;

7. Water recovery rate Through special process design, the equipment's performance has been significantly improvedrate of recovery, up to a maximum of70%；

8. The equipment has an automatic prompt function for consumables replacement, and the replacement cycle of consumables depends on changes in water quality and pressure, rather than the usage time of consumables. Considering the differences in water quality in different regions, the design is more scientific;

9. self-protection The automatic shutdown protection function for source water shortage also has the functions of automatic water production for water tank shortage and automatic shutdown for full water.
