柴油发动机尾气处理设备
摘要：
本发明公开了一种柴油发动机尾气处理设备，包括进气管、油气分离器、氧化催化装置和选择性催化还原器，进气管的底部为进气口，进气管的顶部与油气分离器相连通，氧化催化装置位于选择性催化还原器与油气分离器之间，氧化催化装置的一端与油气分离器相连通，氧化催化装置的另一端与选择性催化还原器相连通，选择性催化还原器远离氧化催化装置的一端的内部设有氨氧化催化剂。尾气从进气管底部的进气口进入柴油发动机尾气处理设备，油气分离器将尾气中的油液分离，经过油气分离器的尾气进入氧化催化装置，氧化催化装置的内部涂覆有贵金属催化剂，氧化催化装置将尾气中部分可燃性颗粒物氧化，以及将尾气中的HC和CO等有害气体氧化。
摘要（英）：

The invention discloses a diesel engine tail gas treatment device. The diesel engine tail gas treatment device comprises a gas inflow pipe, an oil and gas separator, an oxidation catalytic device and a selective catalytic reducer; a gas inlet is formed in the bottom of the gas inflow pipe; the top of the gas inflow pipe is communicated with the oil and gas separator; the oxidation catalytic device is located between selective catalytic reducer and the oil and gas separator; one end of the oxidation catalytic device is communicated with the oil and gas separator; the other end of the oxidation catalytic device is communicated with the selective catalytic reducer; and the end, away from the oxidation catalytic device, of the selective catalytic reducer is internally provided with an ammoxidation catalytic agent. Tail gas enters the diesel engine tail gas treatment device from the gas inlet in the bottom of the gas inflow pipe, oil liquid in the tail gas is separated by the oil and gas separator, the tail gas passing through the oil and gas separator enters the oxidation catalytic device, the interior of the oxidation catalytic device is coated with a noble metal catalytic agent, part of combustible particulate matter in the tail gas are oxidized by the oxidation catalytic device, and HC, CO and other harmful gas in the tail gas are oxidized.
