Smoke plume particulate filter device of diesel generator set and method

Abstract

The invention discloses a smoke plume particulate filter device of a diesel generator set and a method. The device comprises a first electronic control stop valve, a second electronic control stop valve, a metal fiber felt particulate filter, an electric self-heating regeneration device, a controller and a smoke mixing and cooling passageway. A diesel engine smoke discharge pipe is connected with a connection pipe divided into two routes. One route of the connection pipe leads to the input end of the metal fiber felt particulate filter through the first electronic control stop valve. The output end of the metal fiber felt particulate filter perpendicularly communicates with the smoke mixing and cooling passageway through a pipeline. The other route of the connection pipe perpendicularly communicates with the smoke mixing and cooling passageway through the second electronic control stop valve. In the method, the first step includes two different work modes, namely, the mode of discharging tail gas after the tail gas passes through filter particulates of the metal fiber felt particulate filter and the mode of directly discharging the tail gas, and in the second step, combustion soot particles are started through the electric self-heating regeneration device. The device and the method have the beneficial effects that the structure is simple, the size is small, firmness and durability are achieved, the device and the method are suitable for being used for field armaments, and maintenance is easy.

Description

technical field [0001] The invention relates to a diesel engine exhaust plume treatment device, in particular to a metal fiber felt particle collection system that effectively filters out soot particles in the diesel engine plume and reduces the temperature of the plume, and also relates to a particle treatment method, which belongs to the infrared Inhibit technology areas. Background technique [0002] Diesel generator sets have good power and fuel economy, and are widely used in power generation equipment. During the working process of the diesel engine, only about one-third of the total heat generated by diesel combustion is converted into effective work, 35% to 40% of the heat is taken away from the exhaust pipe of the engine in the form of exhaust gas, and the rest of the heat is taken away by the radiator and the body. surface take away. Since most of the heat is taken away through the exhaust system, the exhaust system and tail jet become the most prominent sources ...

AI Technical Summary

Problems solved by technology

However, ceramic-based filter materials are inferior to metal-based filter materials in terms of strength, toughness, thermal conductivity, and vibration resistance. During the regeneration process, they are heated unevenly and are prone to thermal stress damage.
