High-Efficiency Honeycomb Ceramic Wall Flow Filters 400cpsi

Product Description

There are three main stages in the process of collecting particles by wall-flow honeycomb ceramic filter: the first stage is deep-bed filtration stage, at which the micropores on the ceramic wall play a filtering role, and the particles are collected through three filtering mechanisms: inertial collision, diffusion and interception, which leads to a rapid decrease in the flow area of exhaust gas and a rapid increase in DPF pressure drop; The second stage is the formation stage of filter cake layer. At this stage, deep bed filtration and filter cake filtration work at the same time, and the pressure drop of the filter body rises gently. At this stage, the filter body has high filtration efficiency and stable work, which is an ideal filtration stage; In the third stage, the filter cake layer has been completely formed. At this time, filter cake filtration becomes the only filtration mode, and the pressure drop increases sharply in this stage. The third stage will lead to excessive backpressure in the exhaust system of diesel engine, which has considerable side effects on the economy and power performance of diesel engine, so DPF needs to be regenerated before that
