Description
Technical Field
The utility model relates to a GPF DPF belt cleaning device especially relates to a need not to dismantle GPF DPF's belt cleaning device.
Background
With the increasing awareness of environmental protection and the guidance of the state on laws and regulations, environmental protection has become the subject of development of various industries. In the automobile industry, because a large amount of automobile exhaust causes great harm to the atmospheric environment every year, national regulations on automobile exhaust emission are becoming stricter. In the sixth stage of the national regulation (emission limit of automotive pollutants and measurement method (sixth stage of china)), due to the requirements of the national regulation on Particulate matters in heavy automobile exhaust, a new component, namely a DPF (Diesel Particulate Filter) has to be additionally arranged in an after-treatment system of a vehicle. Light duty vehicles are also equipped with a GPF (Gasoline Particulate Filter), a ceramic Filter installed in the exhaust system of a Gasoline engine that traps Particulate emissions before they enter the atmosphere. Briefly, GPF/DPF is a filter device for treating particulate matter in automobile exhaust. After GPF/DPF treatment, the particulate matter in the automobile exhaust can be reduced by 70-90%, and the emission requirement of national six regulations on the particulate matter in the automobile exhaust is met.
The GPF/DPF can continuously enrich the particulate matters in the process of treating the particulate matters in the automobile exhaust, so that the exhaust back pressure is high, and the power of an engine is influenced. The process of burning off the collected particulate matter by exhaust gas heating is called regeneration. Whereas the particles being enriched are mainly composed of two substances, namely soot and ash. Soot is the hydrocarbon particulate matter in the exhaust gas, including partially incompletely combusted fuel and engine oil produced during normal operation of the engine. Ash is non-combustible particulate matter including Ca, S, mg 3 (PO4) 2 、CaSO 4 、Zn 3 (PO 4 ) 2 And the like. Since the active and passive regeneration of a vehicle's DPF primarily cleans up the enriched soot, but is not treatable for ash, it is desirableOther means assist GPF/DPF regeneration for ash removal purposes.
At present, the auxiliary GPF/DPF regeneration is mainly carried out in two modes, one mode is high-temperature sintering regeneration, and the other mode is cleaning regeneration by a cleaning agent. The high-temperature sintering GPF/DPF has high regeneration efficiency, but has high energy consumption, and the generated waste gas causes serious pollution to the environment. And the other method adopts a cleaning agent for cleaning, so that the energy consumption is low, the environment is more environment-friendly, and the regeneration efficiency is low. And both the two modes need to disassemble the GPF/DPF, which may damage the liner and the carrier of the GPF/DPF, and the GPF/DPF online cleaning equipment can realize that the GPF/DPF does not need to be disassembled, and the cleaning solution is circularly cleaned, so that the GPF/DPF can realize quick regeneration.
