Technical Field
The invention relates to the technical field of diesel engine tail gas purification experimental equipment, in particular to a pressure drop measuring device for a wood fiber ceramic filter body for experiments.
Background
Particulate Matter (PM) emitted from diesel engines has attracted considerable attention in recent years. On one hand, particulate matters smaller than 0.1 μm in PM discharged by a diesel engine account for the vast majority of the total number of PM particles, and the particles can penetrate into the lung of a human body through the lower respiratory tract of the human body and further permeate into the blood of the human body, thereby causing great harm to human health; on the other hand, the main component of PM is carbon black, which is one of the potential factors causing global warming. The wood fiber ceramic filter body is a PM catcher taking a natural porous microstructure of wood as a biological template, and has the advantages of strong environmental friendliness, low cost and good application prospect. However, the exhaust back pressure rise caused by the PM trapper is not negligible, so the pressure drop measurement of the experimental sample of the wood fiber ceramic filter is one of the key experiments in the development process of the wood fiber ceramic filter. The experimental sample size of the wood fiber ceramic filter body is small, and a reliable sealing device is needed in pressure drop measurement. However, no experimental device suitable for pressure drop measurement of experimental samples of the wood fiber ceramic filter body exists in the market at present, and therefore, an experimental wood fiber ceramic filter body pressure drop measuring device is provided.
