Abstract
The utility model discloses an anti-corrosion structure of a chimney horizontal flue and outer barrel expansion joint area. A groove is dug in the expansion joint; a special concrete binder layer (5) and a U-shaped polytetrafluoroethylene plate layer (8) are paved at the periphery and bottom of the groove in turn; and a mortar leveling layer (7) is filled in the groove. Two ends of the U-shaped polytetrafluoroethylene plate layer (8) are respectively turnup and fixed on concrete at two ends and the surface of the groove, and a ceramic brick isolation wall (9) is built on the surface of the U-shaped polytetrafluoroethylene plate layer; a concrete slope making layer (2) is paved on each of two sides of the U-shaped polytetrafluoroethylene plate layer (9); and the concrete slope making layer (2) and the ceramic brick isolation wall (9) form a slope plane. A rapid maintenance mortar layer (10), an epoxy priming coat (6), a butyl rubber plate (1), a first high strength vitrification ceramic brick layer (4-1), a polytetrafluoroethylene plate (3) and a second high strength vitrification ceramic brick layer (4-2) are arranged on the surface of the slope plane in turn. The anti-corrosion structure has a good anti-corrosion and antiseepage effect while guaranteeing the shock resistance and telescopic effect of the joint.
Description
Technical field
The utility model relates to the anticorrosion structure of chimney, relates in particular to a kind of chimney breeching and urceolus shrinkage joint zone anticorrosion structure.
Background technology
The steam power station need carry out discharging after desulfurization is handled to flue gas again.Flue gas after the desulfurization is a wet flue gas; The corrosion type of its desulfurization wet flue gas comprises sulfuric acid, sulfurous acid, chloride, fluoride etc.; The flue gas grade is a severe corrosive, and low, the high humidity, little from pull out force of this cigarette temperature almost is in full operation under positive pressure state according to the theoretical calculation chimney.The condensate that the desulfurization smoke condensation forms has very strong corrosivity, and concrete chimney is worked under sour environment, corroded by the multiple action of flue gas pressures and humidity, has a strong impact on chimney safe handling and structure durability.
Chimney breeching and zone, urceolus shrinkage joint belong to the privileged sites of this chimney anticorrosion, and the reservation purpose of seam is the effect at aseismatic joint, settlement joint and shrinkage joint.But in wet chimney anticorrosion, this seam is a big difficult point and weak link.Its original purpose of design should be accomplished to keep during to this design of node during wet chimney anticorrosion design, anticorrosion and antiseepage purpose can be played simultaneously again.
The utility model content
The utility model purpose: the purpose of the utility model is to provide a kind of chimney breeching and zone, urceolus shrinkage joint anticorrosion structure of favorable anti-corrosion effect.
Technical scheme: said chimney breeching of the utility model and zone, urceolus shrinkage joint anticorrosion structure; In said shrinkage joint, dig groove; Around the groove and bottom is equipped with concrete adhesive special layer and U type polytetrafluoroethylene (PTFE) flaggy successively; The inside of groove is filled with the mortar levelling layer, and the two ends of said U type polytetrafluoroethylene (PTFE) flaggy flange respectively are fixed on the concrete on groove two ends and surface, have built the Ceramic Tiles divider wall by laying bricks or stones on its surface; The both sides of said Ceramic Tiles divider wall are equipped with the concrete sloping layer respectively, form slope plane with said Ceramic Tiles divider wall; The gradient of slope plane is 5%-8%.
The surface of said slope plane is disposed with quick maintenance screed, epoxy bottom coating, butyl rubber plate, the first high strength vitreous ceramic brick layer, polyfluortetraethylene plate and the second high strength vitreous ceramic brick layer.
Said Ceramic Tiles divider wall forms through acid-resistant and heat-resistant cementing agent and the filling of vitreous ceramic brick.
The utility model compared with prior art, its beneficial effect is: the utility model has reached good anti-corrosion leak-proof effect in the antidetonation that does not influence seam, telescopic action.

Fig. 1 is the utility model structural representation.
The specific embodiment
Be elaborated in the face of the utility model technical scheme down, but the protection domain of the utility model is not limited to said embodiment.
Embodiment 1:Said chimney breeching of the utility model and zone, urceolus shrinkage joint anticorrosion structure; Foreign material in the shrinkage joint that removing is made up of chimney urceolus and breeching are also dug the groove (confirming gash depth and width according to field condition) of the dark wide about 7cm of about 8cm in said shrinkage joint; Around the groove and bottom is equipped with concrete adhesive special layer 5 and U type polytetrafluoroethylene (PTFE) flaggy 8 successively; The inside of groove is filled with mortar levelling layer 7; The two ends of said U type polytetrafluoroethylene (PTFE) flaggy 8 flange respectively are fixed on the concrete on groove two ends and surface; Built Ceramic Tiles divider wall 9 by laying bricks or stones on its surface, said Ceramic Tiles divider wall 9 forms through acid-resistant and heat-resistant cementing agent and the filling of vitreous ceramic brick; The both sides of said Ceramic Tiles divider wall 9 are equipped with concrete sloping layer 2 respectively, form slope plane with said Ceramic Tiles divider wall 9; The gradient of slope plane is 5%-8%.
The surface of said slope plane is disposed with quick maintenance screed 10, epoxy bottom coating 6, butyl rubber plate 1, the first high strength vitreous ceramic brick layer 4-1, polyfluortetraethylene plate 3 and the second high strength vitreous ceramic brick layer 4-2.
As stated, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the utility model that does not break away from the accompanying claims definition, can make various variations in form with on the details to it.
Claims (2)
1. chimney breeching and urceolus shrinkage joint zone anticorrosion structure; It is characterized in that: in said shrinkage joint, dig groove; Around the groove and bottom is equipped with concrete adhesive special layer (5) and U type polytetrafluoroethylene (PTFE) flaggy (8) successively; The inside of groove is filled with mortar levelling layer (7), and the two ends of said U type polytetrafluoroethylene (PTFE) flaggy (8) flange respectively are fixed on the concrete on groove two ends and surface, have built Ceramic Tiles divider wall (9) by laying bricks or stones on its surface; The both sides of said Ceramic Tiles divider wall (9) are equipped with concrete sloping layer (2) respectively, form slope plane with said Ceramic Tiles divider wall (9);
