Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the utility model provides a kind of technical solution:Anti-corrosion shell and tube exchanger, including shell 1, institute
The end for stating shell 1 is equipped with fixed plate 2, and the covering of fixed plate 2 is set on the shell 1, and welded with the shell 1,
The adjacent side of the fixed plate 2 is equipped with cover board 3, and the outer surface of the cover board 3 is equipped with fixing bolt 4, the fixed plate 2 and the lid
Plate 3 is arranged in parallel, and the fixed plate 2 is fixedly connected with the cover board 3 by the fixing bolt 4, and the bottom of the cover board 3 is set
There is pedestal 6, the side of the pedestal 6 is equipped with end plate 7, and the medial surface of the end plate 7 is equipped with heat-exchanging tube bundle 10, the heat-exchanging tube bundle
