Abstract
A novel nonmetal expansion joint comprises skin, heat insulating filler, a pressing plate, a machine frame and a baffle, wherein the skin is connected with the machine frame and the baffle through the pressing plate to form a hollow structure, the hollow structure is filled with the heat insulating filler, one end of the baffle is welded to a connecting pipe, the other end of the baffle is a free end, the gap between the baffle and the connecting pipe is 8 mm wide, and the five layers of skin are combined through silica gel and T530 binder and are silicone rubber-coated glass fiber cloth, a teflon film, 0.7 mm alkali-free glass fiber cloth, a teflon film and teflon-coated glass fiber cloth from outside to inside in sequence.
Description
Technical field
The present invention relates to a kind of non-metal expansion joint, particularly relate to a kind of non-metal expansion joint be applied under Combustion in High Temperature High Sulfur corrosive conditions.
Background technique
The combined unit of production caprolactam, sulphur ammonium produces a large amount of organic liquid wastes, enters air after incinerator burning after desulfurizer makes flue gas up to standard.Organic liquid waste ensures the abundant atomization of extracting liquid, and extracting liquid enters incinerator and carries out pyrolysis, the oxidized generation of sulphur wherein SO
2and SO
3, also have a large amount of N in products of combustion simultaneously
2, the superfluous O of part
2and the NO of trace
x, potassium ion, sodium ion, and enter waste heat boiler from denitration chamber high-temperature flue gas out.First material that is direct and flame heating part is burnt and causes thermal-protective coating to come off, and causes bellows to be out of shape serious, finally burns.
Summary of the invention
For above problem the invention provides a kind of be applied under Combustion in High Temperature High Sulfur corrosive conditions flexible, without installing, counter-force, absorbing, absorption three direction displacement amount are large, corrosion-resistant, the non-metal expansion joint of abrasionproof.
A kind of novel metalloid expansion joint is the invention provides, covering, thermal insulating filling, pressing plate, frame and baffle plate in order to overcome the above problems; Described covering and frame, baffle plate are connected to form hollow structure by pressing plate, and thermal insulating filling is packed in hollow structure; One end of described baffle plate is welded in adapter, and one end is free end in addition, and the gap of baffle plate and adapter is 8mm;
Totally 5 layers, described covering, adopt silica gel and T530 binder to be composited, be followed successively by Silicone Rubber Coated glass fiber cloth, polytetrafluoroethylene film, 0.7 mm alkali-free glass fiber cloth, polytetrafluoroethylene film and teflon coated glass fiber cloth from outside to inside;
Described thermal insulating filling is standard type aluminium silicate wool.
Useful effect:
Easy for installation, simple.The installation of non-metal expansion joint is without the need to redesigning piping support and hanger.Without the need to high request centering, without the need to crane gear.During replacing, needed time is short, and the pipeline that after adapting to pipeline long-term work, foundation settlement causes simultaneously is permanent to be misaligned.Corrosion protection, fills up alumina silicate thermal-protective material in the cavity between the baffle plate of non-metal expansion joint and covering, thermoinsulation material material is standard type aluminium silicate wool, and Long-Time Service temperature can reach 1 000 DEG C.Both can stop medium heat unofficial biography in pipe, and can prevent again dust from gathering at this, the condition that corrosion produces is inadequate; In addition, nonmetallic material used itself are corrosion resistant.
Embodiment
Below the present invention is described in further details.
A kind of novel metalloid expansion joint, covering, thermal insulating filling, pressing plate, frame and baffle plate; Described covering and frame, baffle plate are connected to form hollow structure by pressing plate, and thermal insulating filling is packed in hollow structure; One end of described baffle plate is welded in adapter, and one end is free end in addition, and the gap of baffle plate and adapter is 8mm;
Totally 5 layers, described covering 1, adopt silica gel and T530 binder to be composited, be followed successively by Silicone Rubber Coated glass fiber cloth, polytetrafluoroethylene film, 0.7 mm alkali-free glass fiber cloth, polytetrafluoroethylene film and teflon coated glass fiber cloth from outside to inside;
Described thermal insulating filling is standard type aluminium silicate wool.
The foregoing is only the preferred embodiments of the present invention, be not restricted to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within right of the present invention.
