Abstract
Disclosed is a high-temperature concentric sulfuric acid cooler without anodic protection. A high-silicon stainless steel cooling water pipe is mounted inside a high-silicon stainless steel shell, a baffle plate is disposed on the cooling water pipe, a sulfuric acid inlet and a sulfuric acid outlet are disposed on the upper portion of the shell, water collecting tanks are mounted at two ends of the shell, a cooling water inlet is arranged on the upper portion of the water collecting tank on one side of the sulfuric acid inlet, a cooling water outlet is disposed on the upper portion of the water collecting tank on one side of the sulfuric acid outlet, and a blow-down opening is disposed on the lower portion of the shell. Both the shell and the cooling water pipe are made of DS-1 high-silicon stainless steel materials, an electrical device, namely an anodic protector, is omitted structurally, the high-temperature concentrated sulfuric acid cooler without anodic protection is simple in structure, low in manufacturing cost, reliable in performance, convenient in operation and long in service life, electric energy is saved, and cost is reduced.
Description
Technical field
The utility model relates to the cooling device field, relates in particular to a kind of sulfuric acid cooler.
Background technology
The cooler of each sulfuric acid plant's use is made by 316L stainless steel tube and cooler casing (316L) now.Because of the concentrated sulfuric acid has extremely strong corrosivity, the 316L steel can not bear the corrosion of the concentrated sulfuric acid, therefore on equipment, increase by a cover electric equipment, make to form a kind of anodic protection film on the 316L material, have so just increased production and use cost, have wasted electric energy.In case circuit goes wrong, cooling tube just is corroded, and equipment carries out the replace tubes maintenance with regard to hard stop, has promptly wasted maintenance man-hours, has increased service material again, and maintenance cost is high, and service life is low.
The utility model content
Problems such as the conventional cooler cost is high in order to overcome, waste electric energy, maintenance rate is high, service life is low, the utility model provides a kind of no anodic protection high-temperature concentrated sulfuric acid cooler.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: no anodic protection high-temperature concentrated sulfuric acid cooler; The high silicon stainless steel enclosure interior is installed the high silicon stainless steel cooling water pipe, and cooling water pipe is provided with deflection plate, and housing top is provided with sulfuric acid import and sulfuric acid outlet; Header tank is installed at the housing two ends; The header tank top of sulfuric acid import one side is provided with cooling water inlet, and the header tank top that sulfuric acid exports a side is provided with coolant outlet, and lower housing portion is provided with sewage draining exit.
Said lower housing portion is provided with base.
Said header tank two ends mounting flange.
The no anodic protection high-temperature concentrated sulfuric acid cooler of the utility model, housing and cooling water pipe have all used DS-1 high silicon stainless steel material, have structurally cancelled anodic protection device one cover electrical installation; Simple in structure, cost of manufacture is low, dependable performance; Easy to operate; Saves energy reduces cost, long service life.
Description of drawings
Fig. 1 is the structure chart that the utility model does not have anodic protection high-temperature concentrated sulfuric acid cooler.
The specific embodiment
The structure of the no anodic protection high-temperature concentrated sulfuric acid cooler of the utility model is as shown in Figure 1, the housing 1 inner cooling water pipe 2 of installing, and housing 1 all uses DS-1 high silicon stainless steel material with cooling water pipe 2; Cooling water pipe 2 is provided with deflection plate 3; Deflection plate 3 is used for the baffling of cooling water through cooling water pipe 2, and housing 1 top is provided with sulfuric acid import 6 and sulfuric acid outlet 7; Hot sulfuric acid gets into cooler from sulfuric acid import 6, and cooling is after sulfuric acid outlet 7 outflows.Header tank 5 is installed at housing 1 two ends; Header tank 5 tops of sulfuric acid import 6 one sides are provided with cooling water inlet 8; Header tank 5 tops that sulfuric acid exports 7 one sides are provided with coolant outlet 9; Cooling water gets into cooler through cooling water inlet 8, and the cooling water of heating flows out through coolant outlet 9 after being used to cool off.Housing 1 bottom is provided with sewage draining exit 10, and housing 1 bottom is provided with base 11, is used to support cooler.Header tank 5 two ends mounting flanges 4.
The no anodic protection high-temperature concentrated sulfuric acid cooler of the utility model, housing 1 has all used DS-1 high silicon stainless steel material with cooling water pipe 2, has structurally cancelled anodic protection device one cover electrical installation; Simple in structure, cost of manufacture is low, dependable performance; Easy to operate; Saves energy reduces cost, long service life.
