Abstract
The utility model discloses an improved drying tower for a sulfuric acid device, which comprises a tower body, an acid-resistant pump and a sprayer arranged at the top of the tower body, wherein a sulfuric acid circulation groove is formed at the lower part inside the tower body, the acid-resistant pump is connected to the bottom of the sulfuric acid circulation groove, and the acid-resistant pump is connected with the sprayer. By the application of the improved drying tower, the concentrated sulfuric acid is directly collected in the sulfuric acid circulation groove after water absorption, so as to simplify the structure of the original device. The improved drying tower for the sulfuric acid device has a simple structure, is economical and practical and has promotion values.
Description
Technical field
The utility model relates to sulfuric acid production plant, especially the drying tower of sulfur dioxide furnace gas in the sulphuric acid process.
Background technology
Contain a large amount of steam in the sulfur dioxide furnace gas of producing during by troilite or Sulfur roasting, the sulfur dioxide that is used to produce sulfuric acid need carry out drying before being converted into sulfur trioxide handles, prior art is at the dry sulfur dioxide gas of the drying tower internal spraying concentrated sulfuric acid, the concentrated sulfuric acid after the suction is discharged by the drying tower bottom, inflow is provided with the sulfuric acid circulating slot outside drying tower, because the sulfuric acid circulating slot is separately set in outside the drying tower, it exists, and investment cost is big, floor space is big, shortcomings such as technological process relative complex.
Obviously there is defective in existing sulfuric acid apparatus drying tower, remains to be improved.
Summary of the invention
At the deficiency that existing sulfuric acid apparatus drying tower exists, the utility model aims to provide a kind of improved sulfuric acid tower, to guarantee that this plant investment expense reduces relatively, floor space reduces relatively, technological process is simplified relatively.
For achieving the above object, the technical scheme that the utility model adopted, a kind of improved sulfuric acid apparatus drying tower, comprise body of the tower, acid-proof pump and be arranged on the spray thrower at body of the tower top, to be set to the sulfuric acid circulating slot in the described body of the tower bottom, the bottom of described sulfuric acid circulating slot connects acid-proof pump, and acid-proof pump connects with spray thrower.
After adopting said apparatus, the concentrated sulfuric acid after the suction directly is collected in the sulfuric acid circulating slot, simplifies the structure of original device.
The utility model is simple in structure, and is economical and practical, has promotional value.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
In the accompanying drawing: 1 body of the tower, 2 sulfuric acid circulating slots, 3 acid-proof pumps, 4 spray throwers, 5 sulfur dioxide air inlet pipe, 6 sulfur dioxide escape pipes, 7 control panels.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, improve the sulfuric acid apparatus drying tower, comprise body of the tower 1, acid-proof pump 3 and be arranged on the spray thrower 4 at body of the tower top, described body of the tower bottom is set to sulfuric acid circulating slot 2, because body of the tower body bottom is a cavity, only need the bottom surface sealing just be can be used as sulfuric acid circulating slot 2; In its bottom sides the sulfuric acid outlet is set, series connection acid-proof pump 3 on the outlet, acid-proof pump 3 is by control panel 7 control work, the bottom, one side of body of the tower 1 is provided with sulfur dioxide air inlet pipe 5, need dry sulfur dioxide furnace gas to manage 5 thus and enter body of the tower inside, sulfur dioxide gas is after drying discharged from the sulfur dioxide escape pipe 6 at body of the tower 1 top, enters next process; Certainly with body of the tower 1 a bottom part as sulfuric acid circulating slot 2, compare with original dry body of the tower like this, the whole height of body of the tower 1 need increase, and could guarantee that like this concentrated sulfuric acid spraying fully contacts with the sulfur dioxide furnace gas, could guarantee the drying effect of sulfur dioxide.
In addition, absorption tower, scrubbing tower in existing gas washing in SA production industry as long as adopt body of the tower and groove isolating construction, if carry out integrated transformation, promptly are fabricated to one to the body of the tower on scrubbing tower or absorption tower and circulating slot, all belong to scope of the present utility model.Dry absorption tower, scrubbing tower and the cooling tower of 400,000 tons of/year iron ore system sulfuric acid apparatus of phosphate fertilizer plant of Wengfu Group Co., Ltd. all adopted the incorporate version of tower groove, use as tower on the top of tower, use as circulating slot the bottom, not only save investment cost, saved floor space, and make device compact, easy to operate more, according to the test run situation, effect is fine.
