110 installation process of heat pipe is safer.In the present embodiment, soft tetrafluoro filler can use the O-ring of other materials to substitute, such as：
Perfluoroether, fluorubber and silicon rubber etc..
First sealing structure 150 further includes metal reinforcing plates 162, and metal reinforcing plates 162 are arranged at corrosion-proof casing 120 and position
Between anti-corrosion tube sheet 152 and metal tube sheets 151, metal support tube 157 passes through metal reinforcing plates 162.That is metal reinforcing plates 162
Anti-corrosion tube sheet 152 is arranged at, the intensity of the first sealing structure 150 is further improved, anti-corrosion tube sheet 152 is avoided to deform.Anti-corrosion pipe
Plate 152 and 162 connection mode of metal reinforcing plates using 173 fixed mode of metal bolts, prevent during equipment use because
High temperature and pressure causes 152 deformation of anti-corrosion tube sheet, causes seal leakage.
In the present embodiment, metal tube sheets 151, metal platen 161, metal support tube 157 and metal reinforcing plates 162 are used
Material can be carbon steel, stainless steel, aluminium alloy etc..The connection mode of metal platen 161 and metal tube sheets 151 is except with bolt
173 connections can also use the fixed forms such as welding or viscose glue bonding.
Metal reinforcing plates 162 are also correspondingly provided with through hole, facilitate the peace of carborundum heat exchanger tube 110 and metal support tube 157
Dress, metal platen 161 are correspondingly provided with through hole, refrigerant are facilitated to flow into, heat exchange is carried out in carborundum heat exchanger tube 110.The present embodiment
In, the first sealing structure 150 sets gradually metal platen 161, metal tube along the direction of 130 to the second end socket 140 of the first end socket
Plate 151, metal reinforcing plates 162 and anti-corrosion tube sheet 152, the structure for making the first sealing structure 150 is more secured, and corrosivity is avoided to be situated between
Matter enters the first end socket 130, and the leakage of corrosive liquid is prevented by anti-corrosion tube sheet 152.
Specifically, in first seal 153, phenyl tetrafluoride pad is set gradually along the direction of 130 to the second end socket 140 of the first end socket
Circle, O-ring, tetrafluoro washer, O-ring and tetrafluoro washer avoid refrigerant from entering metal tube sheets 151 with preventing from first through hole 155
In the gap of rotten tube sheet 152, that is, avoid gap leakage of the refrigerant between carborundum heat exchanger tube 110 and metal tube sheets 151.Second
In sealing element 154, along the direction of 130 to the second end socket 140 of the first end socket set gradually tetrafluoro washer, O-ring, tetrafluoro washer,
Soft tetrafluoro filler and tetrafluoro washer avoid Korrosionsmedium from entering metal reinforcing plates 162 at the second through hole 156, that is, avoid
Gap leakage of the corrosive liquid between carborundum heat exchanger tube 110 and anti-corrosion tube sheet 152.
In the present embodiment, the erection sequence of the first sealing structure 150 is first to install anti-corrosion tube sheet 152 successively, metal is strengthened
Plate 162, metal tube sheets 151 and metal platen 161, then carborundum heat exchanger tube 110 is installed, after install successively second seal 154,
Metal support tube 157 and first seal 153 make anti-corrosion tube sheet 152 and metal tube sheets 151 be mounted on first by bolt 173
Between flange 171 and second flange 172, carborundum heat exchanger tube 110 is firmly installed in the first sealing structure 150.First is close
The setting of sealing 153 and second seal 154 makes to use whole gold between 110 and first sealing structure 150 of carborundum heat exchanger tube
Belong to tube sheet 151 and compress airtight and watertight padding, 151 outside of metal tube sheets, 110 displacement of metal perforated plate gland limitation carborundum heat exchanger tube is prevented
Blocking SiClx heat exchanger tube 110 causes carborundum heat exchanger tube 110 to move axially due to fluid scouring and thermal expansion in use.
Anti-corrosion tube sheet 152 is polytetrafluoroethylene (PTFE) tube sheet or steel lining tetrafluoro tube sheet；But both materials are not limited only to, it can
Carry out tube sheet made of corrosion-resistant material.In the present embodiment, anti-corrosion tube sheet 152 for sealing shell-side, use by metal tube sheets 151
In seal pipe side, two pieces of tube sheets individually seal, and either shell-side leakage or the leakage of pipe side can be found in time.
