Exhaust purfication system

Exhaust purification system adopts with the most effective treatment of black smoke ceramic particle trap (DPF) as a core component, break through the traditional water filtration and static electrostatic dust removal method, make the black smoke removal rate reached to 85%-98%, and adopt with the most advanced CCRT technology to clean up the particles catcher automatically without increasement of pollutants and does not produce secondary pollution.

Relevant laws and regulations

According to National Standard GB20891-2007 in the law of Non-road moving diesel engine emission limitation of China (Phase II) : Including limitation to the carbon monoxide (CO), hydrocarbons (HC), nitrogen oxide (NO2) and particulate matter (PM)emissions of non-road mobile diesel engine.

Purification principle

CCRT (Principle of Capture and decompositon Technology)


Continuous catalytic decomposition capture technique, it is composed by the catalytic oxidation unit (DOC) and the trap of load catalyst (DPF), is which a modern Technology of diesel exhaust treatment, developped by the European firstly. Mainly decomposition HC, CO, PM, NOx emissions can be reduced if use special catalyst. CCRT technology can make the carbon smoke(PM) in the capture in the trap burned completely & automatically, while the trap burns into a clean gas.

Principle of DPF particle catcher
Particle trap filter (DPF) is the core technology of FTG purification device, with its own intellectual property rights, DPF is made of silicon carbide ceramic extrusion forming, and formed to porous ceramic wall after the special craft processing, the structure has high efficiency of capturing particles in the exhaust of diesel Genset. The one end of DPF open while the other end is sealed. The gas channel is micropore on the hole wall. The exhaust of the diesel Genset enter into the filter element, and then flow out by the wall flow surface of the entrance channel. The particles were intercepted in the hole, the filtered gas is discharged.
