The invention belongs to the field of air purification devices and in particular relates to a circulation field special-shaped air duct assembly for a haze removal device and a manufacturing method of the circulation field special-shaped air duct assembly. The circulation field special-shaped air duct assembly comprises an expanded air vent (1), a special-shaped air duct (2), an axial flow fan (4) and a filter (3), wherein the air outlet of the expanded air vent (1) is communicated with the air inlet of the special-shaped air duct (2) through the axial flow fan (4); the filter (3) is fixedly arranged at the air outlet of the special-shaped air duct (2); the expanded air vent (1) is of a horn mouth structure; an included angle between the air outlet of the special-shaped air duct (2) and the horizontal direction is 30 degrees. The circulation field special-shaped air duct assembly disclosed by the invention has the advantages of ideal purification effect, high inlet air pressure of the air duct, low boundary r
