Description
Technical field
The utility model relates to a kind of gas washing in SA production equipment, is specifically related to a kind of sulfuric acid cooling device, belongs to a kind of alloy acid cooler.
Background technology
Acid cooler is indispensable a kind of heat transmission equipment in the industries such as sulfuric acid, chemical industry, medicine.Existing acid cooler generally has calandria, shell-and-tube, structural shape such as board-like, but wherein shell-and-tube because of coefficient of heat transfer height, floor space is little, working service is simple etc., and advantage is most widely used.The shell-and-tube acid cooler generally is made of front and back bobbin carriage, housing, tube sheet, deflection plate, distance sink tube etc.The early stage acid cooler that uses generally adopts plain cast iron processing, makes, and adopts the mode of cool water shower to cool off the concentrated sulfuric acid.This equipment heaviness, floor space are big, cooling effect difference and decay resistance are difficult to reach requirement.
General at present employing Mo2Ti is that stainless steel applies the anodic protection technology.The anodic protection acid cooler is made up of potentiostat and acid cooler body; be use the anodic passivity phenomenon with protected equipment as anode; make the hardware surface enter passive state by bigger electric current; and continue by less electric current keeping its passive state, thereby reach the purpose that alleviates metal equipment corrosion.But feed electric current and cross conference generation passivation corrosion; The too small then passivating film of electric current can not be kept, and activation corrosion can take place.Acid control dense and sour temperature also protects antianode the use of acid cooler to produce very significant effects; can increase with the dense reduction of acid at acid temperature one timing protective current; acid dense one regularly protective current can increase with sour temperature rise, so necessarily require the dense and sour temperature of strict control acid in the use of anodic protection acid cooler.The anodic protection acid cooler is to utilize the method for sacrificing cathode to protect anode, and cathode bar belongs to running stores, needs frequent parking checking and replacing.Cathode bar generally adopts F4 (abbreviation of fluoroplastics is a kind of corrosion-and high-temp-resistant insulating materials) sleeve pipe to entangle, and extracts the difficulty that has strengthened maintenance and safeguarded out but often the F4 sleeve pipe is very difficult in maintenance and replacing process.The anodic protection acid cooler equally also is strict to the requirement of cooling water quality, and cooling water is easy fouling when temperature raises, and influences heat exchange efficiency, thereby sour temperature rise makes the equipment corrosion aggravation.The anodic protection acid cooler has so just increased occupation area of equipment for overhauling convenient necessary headspace so that cathode bar is extracted out.In sum, though anodic protection shell-and-tube acid cooler has had improvement than early stage spray calandria acid cooler, still there is the production run instability in it; instrument control is complicated; shortcomings such as the repair and maintenance difficulty is big, cost is high, and cooling water quality requires high, and floor space is big.
The utility model content
