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.
