Embodiment Construction
[0012] The present invention includes a casing 1, on which an acid inlet pipe 2 is arranged, and a plurality of buffer passages 3 arranged obliquely downward are evenly distributed in the circumferential direction under the acid inlet pipe 2, and the buffer passages 3 extend to the casing 1 bottom.
[0013] A section of upturned portion 4 is provided at the end of each buffer channel 3 .
[0014] The inclination of the raised portion 4 is greater than that of the buffer path 3 .
[0015] Several protruding ribs 5 are arranged on the path of the buffer channel 3 .
[0016] The number of buffer lanes 3 provided in the present invention is determined according to specific conditions, and there is no specific requirement.
[0017] The convex strip 5 provided in the present invention can be determined by a structure having a similar function, and it mainly acts as a barrier to the flow of concentrated sulfuric acid.

The invention relates to a concentrated sulfuric acid circulating device which comprises a shell. The shell is provided with an acid inlet pipe, a plurality of obliquely-downward buffer channels are annularly and evenly distributed under the acid inlet pipe, and the buffer channels extend to the bottom of the shell. According to the concentrated sulfuric acid circulating device, the buffer channels are arranged, after concentrated sulfuric acid flow outs of the acid inlet pipe, the flow path of concentrated sulfuric acid is prolonged through conveying of the buffer channels, and therefore the impact force of concentrated sulfuric acid on the bottom of the shell is reduced; cocking parts are arranged, and the inclination degree of the cocking parts is larger than that of the buffer channels; due to the inclination degree, the result that concentrated sulfuric acid is accelerated due to the fact that the buffer channels decline can be counteracted through the short cocking parts; the height of the cocking parts is smaller than that of an acid outlet of the acid inlet pipe, and therefore the speed of concentrated sulfuric acid is further decreased when concentrated sulfuric acid is makes contact with the bottom of the shell; the flow path of concentrated sulfuric acid is further prolonged through arrangement of the cocking parts, and therefore the speed of concentrated sulfuric acid is further decreased due to existence of unavoidable resistance, so that the impact force on the bottom of the shell is decreased.
Description
technical field [0001] The invention relates to a concentrated sulfuric acid circulation device. Background technique [0002] In the production of sulfuric acid, the temperature of 93% sulfuric acid flowing back from the drying tower to the circulation tank is ~70°C, and the temperature of 98% sulfuric acid returning from the absorption tower to the circulation tank is ~110°C, which is highly corrosive. [0003] The concentrated sulfuric acid in the acid inlet pipe of the existing circulating tank has a great impact and abrasion on the bottom of the tank below the acid inlet pipe. The cycle tank does a lot of damage and the acid mix is uneven. Contents of the invention [0004] The purpose of the present invention is to provide a method for reducing the impact on the bottom of the tank when acid is discharged from the acid inlet pipe and avoiding eddy currents in order to improve the service life of the circulation tank. [0005] For this reason, the technical s...
