Exhaust purge system


    

Exhaust purification system adopts the most effective treatment of black smoke ceramic particle trap (DPF) as a core component, break through the traditional water filtration and static electric precipitation method, make the black smoke removal rate reached 85% 98%, and adopt the most advanced CCRT technology to automatically clean up to trap particles, no increase of pollutants, does not produce secondary pollution


 

Relevant laws and regulations

From the law of the People's Republic of China national standard GB20891-2007 ", the road mobile mechanical diesel engine exhaust emissions limits (China Ⅱ phase) : including the road mobile machine with diesel engine exhaust emissions of carbon monoxide (CO) and hydrocarbons (HC), nitrogen oxide (NO2) and particulate matter (PM) emissions than limit.

Purification principle

CCRT (Catalysed Continuously Regenerating Technology) 

 

 

continuous catalytic decomposition capture technique, it is by the catalytic oxidation unit (DOC) and the trap of load catalyst (DPF), a modern Technology for diesel exhaust treatment, put forward by the European first, mainly decomposition HC, CO, PM, besmear again if special catalyst can reduce NOx emissions. CCRT technology allows the capture of carbon smoke (PM) in the trap to completely automatically burn, while the trap burns into a clean gas. 

 

 

Principle of DPF particle catcher

 

Particle trap filter (DPF) as the core technology of FTG purification device, with its own intellectual property rights, DPF is made of silicon carbide ceramic extrusion forming, and after the special craft processing into porous ceramic wall, the structure of capture diesel emergency generator exhaust particles efficiency is extremely high. DPF of each channel in the open end, on the other end sealing, gas channel for hole wall in the pores, diesel generator exhaust from entry into the filter element, and then by the entrance channel flow of wall surface flow, particles were intercepted in the hole, the filtered gas discharge.
