Abstract
A shell-type concentrated sulfuric acid cooler for an efficient anode protection tube belongs to the field of electrochemical protection technology and chemical equipment. The utility model has the characteristics that the heat exchange tube adopts scaling pipe, spiral groove pipe, bellows, striation slot pipe, makes the fluid all produce boundary layer separation stream along the fluid of interior outer pipe wall flow to attenuate boundary layer thickness, thereby strengthened the heat transfer, improved heat exchange efficiency. The equipment volume is small and the manufacturing cost is greatly reduced.
Description
Technical field
The utility model belongs to electrochemical protection technology and chemical industry equipment, relates to a kind of shell-and-tube stainless steel concentrated sulfuric acid cooler.
Background technology
At present; when gas washing in SA production; drying tower, absorption tower are by concentrated sulfuric acid spray and sulfur dioxide, sulfur trioxide gas precursor reactant; concentrated sulfuric acid temperature raises; the concentrated sulfuric acid that goes out tower must cool off; the anodic protection shell-and-tube stainless steel concentrated sulfuric acid cooler of the general employing of Chang Yong sulfuric acid cooler now; its heat transfer element is formed heat-exchanging tube bundle by the stainless steel light pipe; characteristic requirement according to formation of anodic protection passivating film and protection; shell side acid speed generally is controlled in the 1m/s; the viscosity of the concentrated sulfuric acid is bigger in addition, and the boundary layer that forms around the tube wall when conducting heat is thicker.Be subjected to above its overall heat-transfer coefficient that limits and be generally 600--1000W/m2K, heat exchange efficiency is low.Equipment volume is big, the cost height.
Summary of the invention
The purpose of this utility model is exactly to overcome above-mentioned deficiency and a kind of heat transfer element (stainless steel tube bank) of providing is that intensify heat transfer pipe increases heat exchange efficiency.
The solution that realizes the utility model purpose is to comprise cylindrical shell (11), two of cylindrical shell (11) is provided with water tank (1), water tank (1) is provided with water entrance (2), (5), cylindrical shell (11) is provided with the concentrated sulfuric acid and imports and exports (3), (4), at two of cylindrical shell (11) tube sheet (10) is installed, heat exchanger tube (6) is installed on the tube sheet (10), and at the center of cylindrical shell (11) main cathode (14), particularly heat exchanger tube (6) being installed is convergent-divergent pipe, spiral grooved tube, bellows, transversally flute tube.
The structure that is installed in the water tank (1) of cylindrical shell (11) is that the longitudinal section is part ellipse or garden shape end socket.
The utility model has the advantages that the heat exchange efficiency height, under same process conditions, heat exchange area reduces, and equipment volume reduces, and reduces cost significantly.Effectively prevent the generation of incrustation scale.

The specific embodiment
The both ends of the surface of cylindrical shell (11) are fixed with tube sheet (9), and tube sheet (9) is connected with water tank flange (10) by bolt, and water tank flange (10) is connected with water tank (1).The structure of water tank (1) is that the longitudinal section is the end socket of part ellipse or part garden shape, on water tank (1), be provided with water entrance (2), (5), the outside, end socket top at a side water tank (1) is provided with main cathode joint (12), and main cathode joint (12) links to each other with the main cathode (14) that is installed in cylindrical shell (11) center.It is heat exchanger tube (6) that heat-exchanging tube bundle is installed between two tube sheets (9) in cylindrical shell (11), and this heat exchanger tube (6) is an intensify heat transfer pipe, and form is convergent-divergent pipe, spiral grooved tube, bellows, transversally flute tube.Deflection element (8) also is installed in the cylindrical shell (11), and the form of deflection element (8) is that the garden lacks type, ring-like, the excellent type of baffling in garden.On cylindrical shell (11), be provided with the concentrated sulfuric acid and import and export (3), (4).Another form of the present utility model is to be provided with dividing plate (13) in water tank (1), and water tank (1) is divided into two parts, has just become the two-tube-pass structure.
Connect cathodic electricity at main cathode joint (12) during work, cylindrical shell (11) and heat exchanger tube (6) connect anode.High-temperature concentrated sulfuric acid is imported and exported (3) or (4) from the concentrated sulfuric acid and is entered cylindrical shell (11), flows through from heat exchanger tube (6) outside, imports and exports (4) or (3) from the concentrated sulfuric acid again and flows out; Water enters water tank (1) from heat exchanger tube (6) intermediate flow mistake from water entrance (2) or (5), flows out from water entrance (5) or (2).The concentrated sulfuric acid just is cooled like this.
Because what heat exchanger tube (6) adopted is transversally flute tube, bellows, spiral grooved tube, convergent-divergent pipe, shown in Fig. 5-8.By the change of fluid flow form, enhanced tube is interior simultaneously, pipe is outer conducts heat.The outer fluid of pipe shows as: boundary layer separation around the tube wall and obvious attenuate, flow disturbance increases, and makes the outer heat-transfer film coefficient of pipe improve about 5 times than light pipe.Tube fluid is owing to adopted above heat exchange tube structure, and respective change also takes place the tube fluid form, and the intraductal heat transfer coefficient improves more than 2 times, and pipe is interior, pipe is outer has strengthened heat transfer simultaneously, makes the overall heat-transfer coefficient of acid cooler improve more than 20%.
Claims (1)
