Half-surrounded arrangement structure of wet-process desulfurization absorption tower of large-size thermal power plant

The invention provides a half-surrounded arrangement structure of a wet-process desulfurization absorption tower of a large-size thermal power plant. The half-surrounded arrangement structure comprises two axial flow draught fans which are transversely arranged, wherein outlet flues of the two axial flow draught fans gather to form a general flue and then the general flue is connected with the desulfurization absorption tower; the outlet flues of the two axial flow draught fans are in arc-shaped connection toward the same side respectively to form half-surrounded connection, and are combined in the middle to form the general flue; the space between the two axial flow draught fans arranged on the desulfurization absorption tower are surrounded by the two axial flow draught fans and the outlet flues thereof; the desulfurization absorption tower and the two axial flow draught fans are arrayed in parallel; lower brackets of the two axial flow draught fans are used as public construction brackets; the brackets of
