It matches with the cross section profile of tube side inner ring runner (19) and tube side outer ring runner (20)；Plate tube end cap (5) is welded on spiral plate
Pipe head end (26)；
Plate pipe water conservancy diversion elbow (2) takes the shape of the letter U, and respectively there are one sealings to take over (42) at the both ends of plate pipe water conservancy diversion elbow (2), and two sealings connect
The cross section profile of pipe (42) matches with the cross section profile of tube side inner ring runner (19) and tube side outer ring runner (20) respectively；Plate pipe
Water conservancy diversion elbow (2) is welded on spiral plate pipe tail end (25)；
After helical plate heat exchanger assembly, external seal strip (1) radial outside edge connects with housing cylinder (11) inner radial surface
Sealing is touched, interior sealing item (4) radial inside edge contacts sealing with end cap cylinder (12) radially-outer surface；In two adjacent rings spiral
Shell-side flow path (28) is formed between (3) two side external surface of plate pipe；Shell side water inlet pipe (7), shell-side flow path (28), shell side outlet pipe
(8) composition shell side path；Tube side water inlet pipe (16), tube side outer ring runner (20), plate pipe water conservancy diversion elbow (2), tube side inner ring runner
(19), tube side outlet pipe (6) composition tube side path.
2. a kind of helical plate heat exchanger according to claim 1, it is characterised in that：The work of helical plate heat exchanger
It is as process：
In helical plate heat exchanger, tube side medium is successively along tube side water inlet pipe (16), tube side outer ring runner (20), plate pipe
The tube side path flowing of water conservancy diversion elbow (2), tube side inner ring runner (19), tube side outlet pipe (6), shell side medium is successively along shell side
The shell side path flowing of water inlet pipe (7), shell-side flow path (28), shell side outlet pipe (8), tube side medium and shell side medium are with spiral plate
It is that heat transfer element carries out heat exchange to manage (3)；
In cleaning, spiral plate duct member takes out helical plate heat exchanger from heat exchanger cavity, and two component of end cap is fixed,
Spiral plate pipe tail end (25) is pulled, the spacing between (3) two side external surface of two adjacent rings spiral plate pipe increases, shell easy to clean
Dirt in Cheng Liudao (28).
