Schematic view of the AGN structure assumed in this work. Dust extends from the dust evaporation radius at pc/ 10 ≤ r_in ≤ pc/2 up to distance of r_out = 170 × r_in from the black-hole (BH). We note that dust from the smooth disk emerges also as a diffuse component into the polar region. Dust clouds are pc sized with cube length of d = 3 × r_in. The hot, warm and cold side of the clouds is indicated and for one clump their shadows. The accretion disk in the immediate black-hole environment and the jet is not treated.
