Flow equalizing structure of large-diameter tower body and large-diameter tower body

Abstract

The invention discloses a flow equalizing structure of a large-diameter tower body and the large-diameter tower body. The flow equalizing structure comprises a perforated plate, an upper conical section, a pipe bundle and a lower conical section which are sequentially arranged from top to bottom, the lower conical section is provided with a big-end-down lower conical cavity, the top of the lower conical cavity is locally sealed, and the bottom of the lower conical cavity is open, so that the lower conical cavity is communicated with a tower body inlet section; the upper conical section is provided with an upper conical cavity with a large top and a small bottom, the bottom of the upper conical cavity is partially sealed, and the top of the upper conical cavity is open; a plurality of holesare formed in the perforated plate; the tube bundle comprises a plurality of straight tubes, and the straight tubes of the tube bundle are communicated between the lower conical section and the upperconical section, so that flue gas at the inlet section of the tower body sequentially passes through the lower conical cavity, the tube bundle, the upper conical cavity and the perforated plate and then enters a reaction area in the tower body. According to the flow equalizing structure of the large-diameter tower body and the large-diameter tower body with the flow equalizing structure, the uniformity of a flow field in the tower body can be greatly improved, and the treatment effect of flue gas in the tower body can be improved.

Description

technical field [0001] The invention relates to the environmental protection technology in the field of iron and steel smelting, in particular to a flow equalizing structure of a large-diameter tower body and the large-diameter tower body. Background technique [0002] Dust removal, desulfurization, acid removal and other fields in the iron and steel industry all involve the problem of flow equalization in large diameter towers. Whether the flow field in the tower is uniform or not is the key factor restricting the energy saving and emission reduction effects in the above fields. At present, the diameter of the large-diameter tower often exceeds 8 meters, and the flue gas often enters from the side of the tower, so the uniformity of the flow field in the tower is often poor. Although a large number of flow diversion and flow equalization measures have been added to the existing large-diameter spray towers, it is often difficult to obtain satisfactory results in actual operat...
