Abstract

The invention discloses an exhaust particulate matter charging and charging capacity measuring device of a diesel engine. The exhaust particulate matter charging and charging capacity measuring device comprises a water removal device, a charging reactor and a Faraday cylinder of an improved structure. The water removal device comprises a cooling system and a heating system. The charging reactor comprises a bobbin type corona generator and a positive / negative high voltage power source. The Faraday cylinder of the improved structure comprises a PVC pipe, a first metal net, a second metal net, a rubber pipe, a filter paper bracket, a quick connector, a stainless steel inner barrel, a stainless steel outer barrel and a flow control system. Water in exhaust of the diesel engine is reduced through the cooling system, the exhaust is made to be constant at certain temperature through the heating system, the heated exhaust is then introduced into the charging reactor to react, and therefore particulate matter is charged. On-line measurement is adopted in the whole charging capacity measurement process, the charging capacity of the particulate matter is measured through the Faraday cylinder of the improved structure, and the charged particulate matter is captured through filter paper. By means of the positive / negative high voltage corona discharge technology, real-time capturing of the particulate matter of the diesel engine and measurement of the charging capacity are achieved.

Description

technical field [0001] The invention relates to the technical field of post-treatment of engine exhaust, in particular, it is a device suitable for charging and measuring the charging amount of diesel engine exhaust particulate matter. Background technique [0002] Air pollution caused by the emission of inhalable particulate matter has become one of the most serious environmental problems in this century. The smaller the particle size of inhalable particles, the longer the particle suspension time and transport distance in the atmosphere, the greater the harm to human health. The latest research shows that particles with a particle size of less than 100nm can easily penetrate the cell wall of the human body, enter the blood and brain, and even cause some genetic diseases. At present, the exhaust pollutants of motor vehicles in cities, especially the micronano particles emitted by diesel engines, are one of the main sources of inhalable particulate matter in the atmosphere....
