Further, the air inlet side steam main pipe, go out gas side steam main pipe be one end open and what the other end was closed Tube body opens up the quantity mounting hole consistent with heat exchanger tube quantity on the side wall of the tube body, and each heat exchanger tube is inserted into correspondence respectively Mounting hole in and be welded to connect one.
Further, the heat exchanger tube and air inlet side steam main pipe and the weld seam appearance that gas side steam main pipe is welded to connect is gone out Face is also coated with anticorrosive paint layer.
Further, the heat exchanger tube and air inlet side steam main pipe and go out gas side steam main pipe and pass through argon arc welding welding company It connects.
Further, the seamless U-shaped pipe is molded with or is integrally cast by straight tube material integrally bending.
Further, the air inlet side steam main pipe, go out gas side steam main pipe and heat exchanger tube is made using stainless steel tube.
Using above-mentioned technical proposal, the utility model embodiment at least has the advantages that:The utility model is implemented Example forms the heat exchanger tube by using seamless U-shaped pipe, and heat exchanger tube is only with the air inlet side steam main pipe and going out gas side Steam main pipe junction implements welding and forms weld seam, and in actual use, corrosion-resistant heat exchanger is with the main part of heat exchanger tube Sub-dip enters to exchange heat in the corrosive solutions such as pickle, and all weld seams are respectively positioned on corrosive solution ullage and do not connect directly Corrosive solution is touched, it is possible to prevente effectively from weld seam being corroded property solution corrosion, so as to extend the service life of heat exchanger.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, it can also be obtained according to these attached drawings the scope that other attached drawings still fall within the utility model.
Fig. 1 is the structure diagram of the utility model corrosion-resistant heat exchanger one embodiment.
Fig. 2 is the use state diagram of the utility model corrosion-resistant heat exchanger.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.It should be appreciated that following Illustrative examples and explanation are only used for explaining the utility model, are not intended to limit the scope of the present invention, moreover, not rushing In the case of prominent, the feature in embodiment and embodiment in the utility model can be combined with each other.
As shown in Figure 1 to Figure 2, the utility model one embodiment provides a kind of corrosion-resistant heat exchanger, including air inlet side Steam main pipe 1 goes out gas side steam main pipe 2 and more are connected in parallel in the air inlet side steam main pipe 1 and to go out gas side steam female Heat exchanger tube 3 between pipe 2, the heat exchanger tube 3 are seamless U-shaped pipe, and the heat exchanger tube 3 is with two free ends of seamless U-shaped pipe point Dui Ying not be with the air inlet side steam main pipe 1 and going out gas side steam main pipe 2 and being welded to connect, the inner cavity of heat exchanger tube 3 and the air inlet The perforation corresponding with the inner cavity for going out gas side steam main pipe 2 of side steam main pipe 1.
The utility model embodiment forms the heat exchanger tube 3 by using seamless U-shaped pipe, heat exchanger tube 3 be only with institute It states air inlet side steam main pipe 1 and goes out the implementation welding of 2 junction of gas side steam main pipe and form weld seam, and in actual use, such as Fig. 2 It is shown, it is carried out in the corrosive solutions such as pickle that corrosion-resistant heat exchanger is immersed with the main part of heat exchanger tube 3 in descaling bath 5 Heat exchange, heat-conducting medium(Can be steam, oil, water etc.)Enter from 1 one end open of air inlet side steam main pipe, after flowing through heat exchanger tube 3 Again from go out 2 one end open of gas side steam main pipe outflow.And due to the air inlet side steam main pipe 1 and go out gas side steam main pipe 2 Pickle liquid level can be higher than, it is natural but also all weld seams 4 are respectively positioned on corrosive solution ullage(It usually has at least The difference in height of 200mm)Corrosive solution will not be directly contacted, so as to effectively avoid weld seam being corroded property solution corrosion, And it can effectively extend the service life of heat exchanger.
