Dark reaction catalytic converter suitable for hang membrane catalyst

The utility model relates to a dark reaction catalytic converter of individual string of membrane catalyst, its technical scheme is: whole device includes a reactor main part. The reactor main part comprises quartz glass tube and backward flow hollow layer. The backward flow hollow layer comprise quartz glass, arranges quartz glass outside of tubes layer in and form the integrative airtight structure of double -deck cavity with the quartz glass union coupling together, and the outer both sides of backward flow hollow layer respectively have interface no. 1, interface no. 2 from top to bottom for connecting circulation backflow water controlled reaction temperature, guaranteeing that the reactor moderate temperature is invariable, interface no. 1 is water inlet, interface policy of "literature and art should serve both people and socialism" delivery port. Backward flow hollow layer paints the outside and hides light -absorbing coating, and the influence of illumination to the reaction is got rid of in the requ
