Working principle of SCR System
4NH3 + 4NO + O2→ 4N2 + 6H2O
8NH3 + 6NO2→7N2 + 12H2O
2NH3 + NO + NO2→2N2 + 3H2O
The ammonia needed for the SCR reaction comes from the hydrolysis of a urea solution:
CO(NH2)2 + H2O CO2+ 2NH3
COMPLETE SCR SYSTEM WORKING
The SCR system adopts an injection system with compressed air assistance. The urea solution supply pump is equipped with a built-in control device, which can control the internal urea solution supply pump and compressed air solenoid valve to operate according to established procedures.
Product Advantages
1.Excellent thermal shock resistance.
2.Unique cellular designs make metal liquid reducing the vortex and raducing the bubbles in the casing;
3.Accurate extrusion die make product quality extremely stable and consistency;
4.Obvious filter effect;
5.Improving the casting surface performance and improving the density of the casting;
6.Improving metal structure and quality prolong the working life of the casting;
7.Good chemical stability,not affected by of melted metal,no change in its chemical compound;
8.Precise dimension and can be used in pruduction line automatic filter mounting
