Thin-tube-plate segment anodic protection stainless steel shell-and-tube concentrated sulfuric acid cooling tower

Abstract

The invention discloses a thin-tube-plate segment anodic protection stainless steel shell-and-tube concentrated sulfuric acid cooling tower. The cooling tower is an independent operating unit consisting of a shell side, a tube side and an anodic protection component; and two ends of a cylinder body of the shell side are connected with a cylinder body of a water tank which belongs to the tube side. The cooling tower is characterized in that: a sealing device fixing heat exchange tube bundles and the two ends of the shell side is formed on the inner wall at the two ends of the cylinder body of the shell side by welding a fixed tube plate; and the tube plate is positioned at the inner side on the periphery of the inner wall at the two ends of the cylinder body of the shell side, and the cylinder body of the shell side is welded with the cylinder body of the water tank for sealing connection; and two or more independent operating units are serially connected and divided into one or more high-temperature segment operating systems and one or more low-temperature segment operating systems with same or different number according to temperature. The cooling tower can solve the technical problems of high equipment investment cost, huge abandonment loss and the like of concentrated sulfuric acid coolers due to excessive use of stainless steel in the traditional concentrated sulfuric acid coolers.

Description

technical field [0001] The invention relates to chemical machinery and equipment, in particular to a thin tube plate segmented anode protection stainless steel tube and shell type concentrated sulfuric acid cooling tower. Background technique [0002] The "anodized stainless steel shell-and-tube concentrated sulfuric acid cooler" currently used in the sulfuric acid production system is a fixed tube-plate heat exchanger, such as figure 1 shown. It is composed of a shell side and a tube side. The shell side takes concentrated sulfuric acid, which flows through the inlet acid pipe, the inner side of the shell side cylinder (between the inner sides of the two thin tube sheets), the heat exchange tube bundle, the baffle, and the outlet. The acid runners formed by the acid pipes are made of stainless steel. The cooling water flows through the tube side, and flows through the inlet water pipe, the outlet water pipe, the water side of the left water tank flat cover, the right wate...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an improved thin tube plate segmented anode protection stainless steel shell and shell type concentrated sulfuric acid cooling tower to solve the equipment investment cost of the concentrated sulfuric acid cooler caused by the large amount of stainless steel used in the traditional concentrated sulfuric acid cooler Technical problems such as high and large scrap loss
