SCR System Doc/DPF Catalytic Converters for 50kw-5000kw Diesel Generators

Diesel Oxidation Catalyst(DOC): It is a structure coated with an oxidized noble metal catalyst coating on the surface of a honeycomb shaped ceramic carrier. It can oxidize most of the carbon monoxide (CO), hydrocarbons (CH), and most of the soluble organic matter (SOF) in particulate matter (PM) in tail gas. The conversion efficiency of DOC for CH and CO is about 80% -90%, and the reaction efficiency for SOF is about 30%. And the oxidation reaction process will generate a large amount of heat, providing the required reaction temperature for SCR reaction or passive regeneration of CDPF.

Diesel Particulate Filter (DPF): It is currently considered the most effective and technologically mature device for reducing PM emissions. DPF utilizes inertial collision, interception, diffusion, and gravity settling mechanisms to filter PM out of exhaust gas. The capture efficiency of DPF for PM in exhaust gas can reach about 95%.

The NOx conversion efficiency of the urea SCR system is influenced by many factors, including fuel quality, exhaust temperature, exhaust flow rate, and original NOx concentration; SCR mainly involves factors such as catalyst performance, urea solution injection control strategy, urea solution atomization quality, decomposition and mixing uniformity of urea droplets. The current key research work is mainly focused on two aspects: catalytic converters and urea injection systems.
Type:Honeycomb,Flat,Corrugated plate.

1.DOC reaction temperature is more than 180ºC.
2.The conversion efficiency of CH and CO reaches about 80% -90%.
3.Oxidative injection of HC (fuel) rapidly increases the exhaust temperature after DOC, achieving active regeneration.

1. Pores are smaller than the diameter of PM, and PM in the exhaust gas is intercepted after passing through the carrier, completing the capture of particulate matter.
2. The capture efficiency of PM is high, reaching up to 95%.

1. Using urea as a reducing agent is safe and reliable;
2. Minor modifications to the original unit, resulting in low renovation costs;
3. Debugging, start stop, and operation do not affect the normal operation of the internal combustion engine.
4. The denitrification rate can reach over 90%, NH3 escape is less than 5ppm, the equipment has high efficiency, and there are basically no secondary pollutants
