Problems solved by technology

The plate acid cooler obviously cannot meet the requirements of the production process
Anodically protected stainless steel shell-and-tube baffle acid coolers often leak due to the vibration of the heat exchange tubes and the high flow rate of high-temperature sulfuric acid under such high-flow conditions. It can increase the diameter of the acid cooler shell and the tube spacing of the heat exchange tubes, which greatly increases the cost of the acid cooler

Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawing:

[0035] Below in conjunction with the preferred embodiment shown in accompanying drawing, be described in further detail:

[0036] See figure 1 , figure 2 , image 3 , an anode protection baffle rod acid cooler according to the present invention, an anode protection baffle rod acid cooler, comprising an acid cooler housing 12, a heat exchange tube box is arranged inside the acid cooler housing 12, The heat exchange tube box includes several baffles 10. The baffles 10 are composed of baffle rods a and baffle rings b. The baffle ring b is provided with a plurality of baffle rods a and the baffles on adjacent baffle rings b are The flow rods a are staggered to form a grid structure of staggered rows in space, and the heat exchange tubes 13 are arranged in the space of the grid structure, that is, the heat exchange tubes 13 are fixed by a plurality of staggered baffle rods ...

Abstract

The invention relates to an anodic protection baffle rod type acid cooler which comprises an acid cooler shell (12) and is characterized in that a heat exchange tube box is arranged in the acid cooler shell (12); the heat exchange tube box comprises a plurality of baffle plates (10); the baffle plates (10) comprise baffle rods (a) and baffle rings (b); a plurality of baffle rods (a) are arranged on the baffle rings (b), and the baffle rods (a) on adjacent baffle rings (b) are arranged in a staggered mode to form a spatial staggered grid structure; and a heat exchange tube (13) is arranged in the spatial grid structure. The anodic protection baffle rod type acid cooler of the invention has reasonable design, reduces the vibration of the heat exchange tube, improves the heat transfer coefficient, reduces the consumption of the kinetic energy, has good anodic protection effect, low corrosion rate, safety and reliability, and absolutely can be used under the technological conditions of high acid content; and compared with an anodic protection baffle plate type acid cooler, the comprehensive economic benefit is greatly improved.

Description

technical field [0001] The present invention mainly relates to the equipment in the contact method acid production device, in particular to an anode protection baffle rod acid cooler, the acid cooler is a kind of anode protection concentrated sulfuric acid stainless steel acid cooler in the dry suction section of the acid production device . Background technique [0002] At present, 93% concentrated sulfuric acid is used in the dry suction section of the sulfuric acid production plant to dry the humid furnace gas, and at the same time, 98% concentrated sulfuric acid is used to absorb SO3 gas to produce acid. The process is: circulating acid tank→acid pump→acid cooler→tower→ In the circulating acid tank, reaction heat is generated during this process, and the temperature of 93% and 98% concentrated sulfuric acid will rise, and the heat will be taken away by the acid cooler through the circulating water. Once the acid cooler leaks acid, the entire sulfuric acid system will be...
