Abstract

The utility model relates to a pot type sulphuric acid concentration device for concentrating sulphuric acid, which mainly solves the problems that the inner walls of the sulphuric acid cooler of theprior sulphuric acid concentration device which is internally sleeved and contacts liquid level is easily eroded and the like, and consists of a sulphuric acid cooler, a bubble-cap tower, a pot body and a decompressor. The sulphuric acid cooler comprises an outer sleeve, an acid outlet, a dreg outlet and an inner sleeve; a pipeline communicated with the pot body, a pot cover and the bubble-cap tower are arranged in the inner sleeve; the bubble-cap tower comprises a bubble-cap tower section, a supporting ring, a bubble cap and a liquid separating plate; a flange is arranged on the top of the bubble-cap tower, the flange is fixed with the pot cover by a long bolt, and a feed inlet is arranged on the upper part of the bubble-cap tower; the decompressor comprises an outside decompressor shell,a steam inlet and a decompressor sleeve; a phosphoriser-shaped sleeve is installed on the bulge of the inner wall of the inner sleeve of the sulphuric acid cooler; the bubble-cap tower section and the supporting ring are of respectively separate castings; and the decompressor sleeve is inserted into the plug socket arranged on the upper end of the outer decompressor shell and adopts an inner holelocating structure. The pot type sulphuric acid concentration device has the advantages that corrosion on the joint between the inner wall and the liquid level is reduced and the service life is long.

Description

Cooking-pot type sulphuric acid concentration device

Technical field:

The utility model relates to a kind of device that dilute sulfuric acid is concentrated.

Background technology:

Existing sulphuric acid concentration device comprises compositions such as sulfuric acid cooler, bubble column, pot body and pressure reducer, and shortcoming is the interior cover inwall liquid level place corrosion-vulnerable of sulfuric acid cooler, and generally only be 1-1.5 service life; Bubble column is formed by stacking by circular bubble columns joint that several have support ring, because bubble-cap joint and support ring are cast in block, so processing difficulties, during casting and fragile in the use, qualified casting is low; The pressure reducer shell upper end of pressure reducer is cast with flange, often forbidden to cause hydraulic loss big and flange is also fragile because of contraposition, because inserting mouth, decompression body upper sleeve portion adopts the groove type location again with sleeve pipe, the required precision height, and difficulty of processing is big, dismounting inconvenience, in addition, because sleeve pipe adopts cylindrical shape, fin is arranged at the circle tube inner wall bottom, resistance to water-flow is big, and energy loss is many.

Summary of the invention:

Technical problem to be solved in the utility model provides a kind of corrosion that can reduce cover inwall liquid level place in the sulfuric acid cooler, increase the service life, the bubble column joint helps casting and extends working time, improve yield rate, the cooking-pot type sulphuric acid concentration device that the pressure reducer shell that guarantees pressure reducer and pipeline accurately are connected.

Above-mentioned purpose is achieved in that this device is by sulfuric acid cooler, bubble column, pot body and pressure reducer are formed, sulfuric acid cooler comprises overcoat, there is the acid mouth on overcoat top, slag notch is arranged at the bottom, there is interior cover the overcoat the inside, interior cover top is uncovered structure, cooling water adds from here, in be with pipeline with the pot body be communicated with, be stamped pot cover above the pot body, there is interface to be communicated with on the pot cover with bubble column, bubble column is formed by stacking by some joint bubble column joints, in each bubble column joint a support ring is arranged all, adorn a bubble-cap on each support ring, adorn a separatory dish below each bubble-cap, the bubble column cat head has flange, there is stay bolt that tower body and pot cover are connected and fixed between this flange and the pot cover, tower top has charging aperture to be connected with the dilute sulfuric acid pipeline, the vapor outlet port of cat head adopts vacuum pipeline to be connected with the pressure reducer air intake, pressure reducer comprises the pressure reducer shell, the pressure reducer air intake is located at a side of pressure reducer shell, the pressure reducer sleeve pipe is inserted in the insertion mouth of pressure reducer shell upper end, for being connected with the entry pipeline, unlike the prior art be: cover inwall middle and upper part is provided with boss in the sulfuric acid cooler, have the bell shape lining to be placed on the boss of interior cover inwall, the finished acid pipeline of cover and pot body inserts from interior cover top in being communicated with; Bubble column joint and support ring are foundry goods independently separately, and support ring places in the bubble column joint; On the pressure reducer shell outer wall suitable for reading flange is arranged, has flange alive to be stuck on the flange, for the entry pipeline on flange be connected and fixed; The pressure reducer sleeve pipe is inserted in the insertion mouth of pressure reducer shell upper end, adopts the endoporus location structure; The pressure reducer sleeve pipe is conical, thereby reduces internal drag, makes fluid flow pattern steady.

The utility model has the advantages that: owing in the cover inwall high-silicon cast iron lining is arranged in the sulfuric acid cooler, inwall is shielded, reduce the corrosion at inwall liquid level place, through test, can reach 2.5-3 service life; Again because bubble column joint and support ring are foundry goods independently separately, institute is so that processing, the finished casting rate height; Because pressure reducer adopts flange alive to be connected with coming water pipeline, so it is easy to connect contraposition, because the insertion mouth of pressure reducer sleeve pipe and pressure reducer shell upper end adopts the endoporus location structure, so pressure reducer shell and the accurate positioning of pressure reducer sleeve pipe; Also because the pressure reducer sleeve pipe is conical, so internal drag is little, fluid flow pattern is steady.
