Description

Recycling apparatus for diesel particle filter used at low temperature {APPARATUS FOR REGENERATING A DIESEL PARTICULATE FILTER AT LOW TEMPERATURE}

The present invention relates to a regeneration device for a diesel particle filter used at a low temperature, and more particularly, a regeneration device for a diesel particle filter used at a low temperature that can be removed in a low temperature state without burning the particulate matter collected in the diesel particle filter. It is about.

In general, a diesel engine has an excellent durability, but compared with a gasoline engine, a diesel engine has a problem of emitting a large amount of nitrogen oxides (NOx) and particulate matter (Particulate Matter).

The particulate matter discharged from the diesel engine is small particles of about 0.1 to 0.4 mu m and floats in the air, causing various diseases such as lung diseases. Therefore, diesel engines are regulated for exhausts, and diesel particulate filters (also referred to as "DPFs") are used to satisfy these emission regulations, and filter particulate matter such as a soot. The diesel particulate filter having a porous structure significantly reduces the emission of particulate matter discharged together with the exhaust gas from the diesel engine.

On the other hand, when the diesel particulate filter is reduced due to the continuous collection of particulate matter to recover the original capturing capacity by regeneration, it is very important not to be damaged during regeneration. The regeneration method of the diesel particulate filter includes a natural regeneration method and a forced regeneration method. In the natural regeneration method, when the chute is sufficiently collected in the diesel particle filter, oxygen is sufficiently supplied to burn the chute. Since the temperature of the diesel particulate filter cannot be controlled, an abnormal temperature of combustion of particulate matter such as a chute may occur, which may cause thermal damage or even melt of the diesel particulate filter. Therefore, due to this problem, the diesel particulate filter is being regenerated by a forced regeneration method, and this forced regeneration method is to suppress the natural regeneration by reducing the amount of air supplied to the engine by lowering the boost pressure.

However, the forced regeneration method of the diesel particle filter calculates the chute trapping amount by using a differential pressure sensor, artificially increases the fuel supply amount and lowers fuel economy as the chute is burned in the diesel particle filter. Due to the heat generated by the combustion of the temperature of the diesel particle filter often exceeds 1000 ℃ has a problem in reducing the durability of the diesel particle filter by reducing the durability.

The present invention is to solve the above-mentioned conventional problems, the object of the present invention is to remove the particulate matter collected in the diesel particle filter in a low temperature state without burning to prevent thermal damage due to high temperature during the regeneration of the diesel particle filter The present invention provides a regeneration device for a diesel particle filter that is used at a low temperature that maintains durability and saves energy consumed in regeneration by not using a heater.
