Abstract
The utility model discloses a sulfuric acid analyzing acid cooler which comprises a cooling water tank body, wherein the cooling water tank body is internally provided with a heat exchange pipe, and is provided with a cooling water inlet and a cooling water outlet; two ends of the cooling water tank body are provided with seal heads; the heat exchange pipe is a spiral heat exchange coil pipe; and two ends of the heat exchange coil pipe are respectively provided with an acid inlet and an acid outlet which extend out of the cooling water tank body. The sulfuric acid analyzing acid cooler provided by the utility model has the advantages that ultra-high-temperature concentrated sulfuric acid with the temperature of 200 DEG C around and sulfuric acid concentration of 99%-99.8% is lowered to the using temperature range of a normally used sulfuric acid concentration analyzer of 60-100 DEG C; and a heat exchange pipe structure of a coil pipe type is adopted, a traditional tube-and-shell-type heat exchange pipe box and a pipe plate are omitted, and the problem of thermal deformation stress of the tube plate and the heat exchange pipe is avoided, and a normally used expansion joint is omitted.
Description
Technical field
The utility model relates to the heat-exchanger rig in a kind of sulfuric acid apparatus, particularly discloses a kind of acid analysis acid cooler.
Background technology
Along with applying of low potential temperature heat recovery technology in the large-scale sulphur-burning sulphuric acid plant, the heat transmission equipment in traditional sulfuric acid apparatus can't satisfy running temperature at corrosion and the performance requirement of 200 ℃ of left and right sides sulfuric acid concentrations at 99% ~ 99.8% the superhigh temperature concentrated sulfuric acid.Especially the specified applied temps of sour dense analyzer of practicality all in 100 ℃, can't satisfy the stability requirement of sour dense analysis feedback to the operation of process heat recovery system in the existing gas washing in SA production.
Summary of the invention
The purpose of the utility model is to overcome the defective that exists in the prior art; Provide a kind of and effectively 200 ℃ of left and right sides sulfuric acid concentrations of temperature are reduced to the serviceability temperature scope of 60 ~ 100 ℃ sulfuric acid concentration analyzer commonly used and simple and practical acid analysis acid cooler at 99% ~ 99.8% the superhigh temperature concentrated sulfuric acid.
The utility model is achieved in that a kind of acid analysis acid cooler; Comprise the cooling water casing; Be provided with heat exchanger tube in the said cooling water casing, said cooling water casing is provided with cooling water inlet, coolant outlet, and the two ends of said cooling water casing are provided with end socket; It is characterized in that: said heat exchanger tube is the spirality heat exchange coil, and the two ends of said heat exchange coil are respectively stretches out the external sour import of cooling water tank, acid outlet.
Said cooling water casing is the tubular casing, and the below of said cooling water casing is provided with saddle.
Said end socket is a flat head, and said end socket and cooling water casing are through the Tetrafluoro spacer sealing.
Said sour import is positioned at the middle and lower part of the cooling water casing of coolant outlet one side, and said acid outlet is positioned at the middle and upper part of the cooling water casing of cooling water inlet one side.
Said cooling water casing is a stainless steel jointless tubular casing.
The beneficial effect of the utility model is: the serviceability temperature scope that effectively 200 ℃ of left and right sides sulfuric acid concentrations of temperature is reduced to 60 ~ 100 ℃ sulfuric acid concentration analyzer commonly used at 99% ~ 99.8% the superhigh temperature concentrated sulfuric acid; Adopt the heat exchange tube structure of coil form, save conventional tube shell heat exchanger bobbin carriage and tube sheet, avoided the problem of tube sheet and heat exchanger tube thermal deformation stress, saved expansion joint commonly used.
