Further, the air inlet side steam main, outlet side steam main be one end open and what the other end was closed
Body, the quantity mounting hole consistent with heat exchanger tube quantity is opened up in the side wall of the body, and each heat exchanger tube inserts correspondingly respectively
Mounting hole in and be welded to connect one.
Further, the weld seam appearance that the heat exchanger tube is welded to connect with air inlet side steam main and outlet side steam main
Face is also coated with anticorrosive paint layer.
Further, the heat exchanger tube is welded by argon arc welding with air inlet side steam main and outlet side steam main and connected
Connect.
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, outlet side steam main and heat exchanger tube are made using stainless steel tube.
Using above-mentioned technical proposal, the embodiment of the present invention at least has the advantages that：The embodiment of the present invention is by adopting
Form the heat exchanger tube with seamless U-shaped pipe, heat exchanger tube be only with the air inlet side steam main and outlet side steam main
Junction implements welding and forms weld seam, and in actual use, corrosion-resistant heat exchanger immerses acid with the main part of heat exchanger tube
Exchanged heat in the corrosive solutions such as washing lotion, and all weld seams are respectively positioned on corrosive solution ullage and are not directly contacted with corrosivity
Solution, it is possible to prevente effectively from weld seam being corroded property solution corrosion, so as to extend the service life of heat exchanger.
