Abstract
The utility model provides a carbon steel titanizing-aluminizing heat exchanger, which comprises a housing and a tube bundle of the heat exchanger; and the tube bunch includes a tube plate and a whirl plate, as well as heat exchanging tubes mounted on the tube plate and the whirl plate. The heat exchanger is characterized in that carbon steel titanizing-aluminizing alloy layers are processed on the inner and the outer surfaces of each heat exchanging tube, and have the thicknesses ranging from 0.1 mm to 0.25 mm. The carbon steel titanizing-aluminizing alloy layers can resist corrosion of wet hydrogen sulfide as well as high-temperature naphthenic acid, chloride ions and other matters, have stronger corrosion resistance than common aluminizing heat exchanger, and can be widely applied to the petrochemical industry.
Description
Technical field
The utility model relates to a kind of industries such as petrochemical industry that are applied to, and finishes the equipment of medium exchange heat, belongs to heat exchanger-type, specifically is that a kind of carbon steel oozes the titanium aluminium heater.
Background technology
In the China's oil chemical industry, the operation medium of equipment becomes increasingly complex, and is more and more serious to the corrosivity of equipment, and the heat exchanger that particularly is widely used is more and more higher to its corrosion resistance requirement.The anticorrosion means of known heat exchanger mainly adopt expensive high alloy resistant material to make heat exchanger tube, heat exchanger tube is the critical piece in the heat transmission equipment, like this because expensive manufacturing, the use cost that causes increasing equipment of heat exchanger tube, at present, the known technology head it off has employing aluminising heat exchanger, but its anti-corrosion effects of some operating mode is unsatisfactory.
The utility model content
The purpose of this utility model is to provide a kind of manufacturing cost lower, and corrosion resistance can better be oozed the titanium aluminium heater by carbon steel.
The utility model is that the technical scheme that is adopted that achieves the above object is: provide a kind of carbon steel to ooze the titanium aluminium heater, it is made up of the shell and the tube bank of heat exchanger, tube bank comprises tube sheet and deflection plate and is installed in heat exchanger tube on them, and the inside and outside surface that it is characterized in that heat exchanger tube all is processed with carbon steel and oozes the titanium-aluminium alloy layer.It is 0.1～0.25mm that the carbon steel on the inside and outside surface of above-mentioned heat exchanger tube oozes the titanium-aluminium alloy layer thickness.
The utility model compared with prior art, the version that has adopted the carbon steel of relative low price on the inside and outside Surface Machining of common steel pipe to ooze the titanium-aluminium alloy layer, carbon steel oozes the titanium-aluminium alloy layer has stronger resistance to corrosion than common aluminising heat exchanger, have and the same resistance to corrosion of expensive high alloy resistant material, but the cost of making heat exchanger is lower than the heat exchanger of high alloy resistant material, and is therefore more advanced than known technology.
Description of drawings
Fig. 1 is the schematic diagram that a kind of carbon steel of the utility model oozes the titanium aluminium heater;
Fig. 2 is the heat exchanger tube cross sectional representation that a kind of carbon steel of the utility model oozes the titanium aluminium heater;
Specific embodiments
The utility model carbon steel oozes the titanium aluminium heater as shown in Figure 1, comprises shell 1 and the heat exchanger tube 2 that is installed on deflection plate 3 and the tube sheet 4, it is characterized in that the carbon steel on the inside and outside surface of heat exchanger tube 2 oozes titanium- aluminium alloy layer 5,6.
It is 0.1～0.25mm that the carbon steel on the inside and outside surface of above-mentioned heat exchanger tube 2 oozes titanium-aluminium alloy layer 1,3 thickness, and this heat exchanger tube can adopt general common steel tube.
As shown in Figure 2, there is the tubing that carbon steel oozes titanium- aluminium alloy layer 5,6 to be assembled into one in inside and outside Surface Machining shown in Figure 1 by tube sheet 4 and deflection plate 3, can constitute heat exchanger tube, then this heat-exchanging tube bundle is assembled in the shell 1 as other heat exchanger tubes and gets final product, carbon steel oozes titanium- aluminium alloy layer 5,6 can moisture-resistant hydrogen sulfide and the corrosion of materials such as high-temperature naphthenic acid and chlorion, and the steel pipe that is processed with carbon steel tube alloy- layer 5,6 can be widely used on the various model shell-and-tube heat exchangers of petroleum chemical industry.
Claims (2)
1. a carbon steel oozes the titanium aluminium heater, comprises shell and is installed in heat exchanger tube on deflection plate and the tube sheet, and the inside and outside surface that it is characterized in that heat exchanger tube all is processed with carbon steel and oozes the titanium-aluminium alloy layer.
