<p>PURPOSE: To provide a miniaturized stack gas treating device advantageous in terms of cost and capable of being continuously operated for a long period. CONSTITUTION: A stack gas is introduced into a reaction vessel 1 from an inlet 1a and irradiated with X-rays from an X-ray generator 6. Consequently, electrons are generated from the NOX and SOX in the stack gas, various reactions are brought about, and the stack gas is converted into a powdery product. The impressed voltage of the X-rays is between several ten and several hundred KeV and about 1/10 of that in the case of electron beam irradiation, and hence the entire device is miniaturized. Meanwhile, since material penetrating power of X-rays is high, an irradiation window 2 is thickened, and the service life of the window 2 is prolonged.</p> |
