Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.Accompanying drawing is the schematic diagram simplified, only with signal side
The basic structure of the formula explanation present invention, therefore it only shows the composition relevant with the present invention.
Specific embodiment, refers to Fig. 1, for the exhaust gas scrubber of low-temperature plasma reactor, including air inlet pipe 1,
Gas drier 2, efficient filter screen 3, exhaust gas washing tower 5, valve positioner 7 and valve 1, described air inlet pipe 1 is arranged on gas
On body drying device 2, described air inlet pipe 1 is provided with valve 2 13, and described gas drier 2 is provided with efficient filter screen 3, described
Efficiently filter screen 3 is provided with low-temperature plasma reactor 4, by even between described low-temperature plasma reactor 4 and exhaust gas washing tower 5
