Combination body of flue gas desulfurization absorption tower and chimney

Abstract

The invention relates to an absorption tower, a chimney and a chimney bracket in a flue gas desulfurization device. A combination body of the absorption tower and the chimney is a whole which is formed by connecting and combining the absorption tower, the chimney and the chimney bracket; the chimney is superposed on the top part of the absorption tower; cylindrical shell sections of the chimney are flexibly connected with each other; pipe nipples on the top of the absorption tower are flexibly connected with the cylindrical shell sections of the chimney; the weights of the cylindrical shell sections in the chimney are borne by sections of the chimney bracket; and an upright post of the chimney bracket is connected with a barrel of the absorption tower in positioning connecting modes, such as welding, threading and pivoting and the like into a whole. Compared with a device in which the chimney and the absorption tower are arranged separately, the combination body of the absorption tower and the chimney can reduce the floor area needed by the arrangement of the absorption tower and the chimney and reduce the construction investment and maintenance cost of the combination body of the absorption tower and the chimney.

Description

technical field [0001] The invention relates to equipment in a flue gas desulfurization device, in particular to an absorption tower, a chimney, a chimney support in the flue gas desulfurization device, and their mutual combination and connection structure. Background technique [0002] In the existing flue gas desulfurization device, the net flue gas from the absorption tower is discharged into the atmosphere after entering the chimney arranged separately through the connecting pipe, that is, the absorption tower and the chimney are arranged separately, and are connected to each other through pipes, and the chimney It needs to be built from the ground. Therefore, the flue gas desulfurization device arranged in this way requires a large area, and the construction investment and maintenance costs are high. Contents of the invention [0003] The technical problem to be solved by the present invention is to improve the combination mode and connection structure between the abs...

Problems solved by technology

[0002] In the existing flue gas desulfurization device, the net flue gas from the absorption tower is discharged into the atmosphere after entering the chimney arranged separately through the connecting pipe, that is, the absorption tower and the chimney are arranged separately, and are connected to each other through pipes, and the chimney It needs to be built from the ground. Therefore, the flue gas desulfurization device arranged in this way requires a large area, and the construction investment and maintenance costs are relatively high.
