For preventing that the intravital filler fragment in dry tower body or absorption tower from causing erosion to the pump housing to the drift about local diluted acid that forms at sour face of the damage of the pump housing and the intravital make up water of concentrated acid circulation groove, in concentrated acid circulation cell body, be provided with sour partition wall between the concentrated acid recycle pump of transition section and recycle acid pumping hole below.Thereby can be with filler fragment retaining in the wall bottom, and allow float and have the acid solution of water face to flow to circulation cell body inwall one side is circuitous along sour partition wall, so that the fully mutual tumble mixed of water liquid level and acid solution face, form the high concentrated acid solution of concentration stabilize, thereby the qualified concentrated sulfuric acid solution of assurance output circulates and produces qualified finished acid.This high concentrated acid solution enters in the concentrated acid circulation cell body through the vertical mixing acid of sour partition wall passageway breach.
Above-mentioned base is welded into one-piece construction by base plate and section steel beam, to be born drying by base integral body or to absorb tower body and concentrated acid circulation groove body weight.And should the drying tower body or absorb tower body and concentrated acid circulation cell body directly is seated on the ground foundation of civil work table top that is complementary with its shape by base.
The utility model compared with prior art has following advantage:
1, because tower body and cell body connect into an integral body, and directly is located on the ground on the foundation of civil work table top, cancelled civil engineering tower platform by a unsplit bedplate.Foundation of civil work simple shape, whole stressed area the ground pressure to foundation of civil work greatly are little relatively, thereby have saved a large amount of civil engineering costs.
2, since tower body and cell body be located at grade, so owing to the tower platform has been cancelled in drying, the absorption tower of tower groove one in configuration, make the concentrated acid water cooler can be placed on the vacant lot between two towers (dry with absorption tower or drying and two absorption towers), with tower, groove is parallel controls, form floor space with respect to tower, groove separate configuration is much smaller, meets the spirit that national requirements is saved the area.
3, because tower body and cell body are located at grade, so the lifting lift of recycle acid reduces greatly, only needs allocating power less, the cyclic acid pump that lift is lower.The all corresponding reduction of equipment purchase expense and production run expense.
4, because tower body and cell body have connected into an integral body, saved go back to acid tube road of recycle acid, cancelled pipeline acid seal device.Because the concentrated acid water cooler is arranged side by side with tower body, make that the recycle acid route of pipe line is very compact and succinct between tower and the groove again between Liang Ta.Compare with traditional tower groove form arranged apart, its recycle acid pipe-line contraction in length is about 60%, has both significantly reduced pipeline fabrication and installation cost, has significantly reduced the leak point on the acid tube road again, is more conducive to production management and maintenance and repair.
