On fixed circle, the other end is arranged on chimney outer barrel.
Preferably, the Corrosion Protection of Fiber Reinforced Plastics chimney, it is characterised in that described chimney outer barrel is conventional concrete and steelframe
The outer tube structure of structure.
Preferably, the bottom of the Corrosion Protection of Fiber Reinforced Plastics chimney in the Corrosion Protection of Fiber Reinforced Plastics chimney is provided with captation.
The present invention compared with the existing technology has advantages below and effect：
1st, because chimney inner cylinder uses glass fibre reinforced plastic structure, antiseptic property is good.
2nd, chimney internal cylinder is telescopic connection, glass steel material structure, and two shell ring joint portions are processed using frosting technology, set
The frosting technology treatment of cylinder joint portion increased the compactness between sleeve, and interaction force is stronger after wetting, and chimney is more firm, together
When also to expand with heat and contract with cold there is provided corresponding space.
3rd, the telescopic junction inside and outside of chimney internal cylinder are all fiberglass sealed circle ruggedized construction, internal sealing
It is the triangular shaped projection of chamfer to enclose, and raised width gradually increases upwards along chimney wall, is conducive to improving chimney breast
Flue gas flow rate, improves plume rise height, and chimney internal cylinder weight reduction.
4th, the center line of reducing flue intersects with the center line of chimney internal cylinder, and reducing flue includes conventional position and varying diameter portion
Position, the reducing position forms reducing obliquely for flue lower end, is conducive to improving flue gas flow rate.
5th, the stainless steel retainer plate and 4~12 conventional shock absorbers installed on the certain altitude of Corrosion Protection of Fiber Reinforced Plastics chimney,
Conventional shock absorber one end is arranged on stainless steel retainer plate, and the other end is arranged on chimney outer barrel, makes whole chimney structure more
It is firm.
6th, chimney internal cylinder inwall sets fluted, and the bottom of Corrosion Protection of Fiber Reinforced Plastics chimney is provided with captation, can be effective
The mordant chimney water of collection belt.
