两种基体复合的POC金属载体后处理器
摘要：
本实用新型涉及一种两种基体复合的POC金属载体后处理器，其特征在于：载体由两种基体泡沫金属饼－A型载体和金属丝网饼－B型载体组成；泡沫金属饼－A型载体和金属丝网饼－B型载体交替排列在载体壳体内，金属载体的进口和出口均为泡沫金属饼，两块泡沫金属饼之间交替放置金属丝网饼－B型载体，泡沫金属饼－A型载体和金属丝网饼－B型载体上涂敷氧化型催化剂涂层；进口和出口的泡沫金属饼－A型载体采用金属挡圈同壳体焊接固定。该载体具有很高的机械强度，应用于车载POC后处理器，发动机排气烟度降低51～72％；无背压问题；在性能相当的情况下，价格相当于进口产品的1/4～1/5，节约成本。
摘要（英）：

The utility model relates to a POC metal carrier postprocessor with two composite substrates. The POC metal carrier postprocessor is characterized in that the carrier consists of foamed metal biscuits(type A carrier) and metal mesh biscuits (type B carrier); the foamed metal biscuits (type A carrier) and the metal mesh biscuits (type B carrier) are stacked alternately in a carrier casing; the foamed metal biscuits (type A carrier) are placed at the inlet and the outlet of the metal carrier; the metal mesh biscuits (type B carrier) are alternately arranged between two foamed metal biscuits; anoxidative catalyst coating is applied on the foamed metal biscuits (type A carrier) and the metal mesh biscuits (type B carrier); and the foamed metal biscuits (type A carrier) at the inlet and the outlet are fixed on the carrier casing through a metal retaining ring by welding. The POC metal carrier postprocessor has high mechanical strength, and is applicable to onboard POC postprocessor to reduce the smoke density of the exhaust of the engine by 51% to 72%. In addition, the POC metal carrier postprocessor has no back pressure, and low cost, which is equivalent to 1/4 to 1/5 the price of the import product with the similar performance.
