Abstract
A corrosion-resistant chimney comprises a chimney, a flue and an expansion joint between outer walls of the flue, and is characterized in that three base layers are wrapped on portions, vacated by foam glass bricks, on two sides of the expansion joint, and the three base layers on the outer walls of the flue sequentially include a flexible acid-resisting corrosion-resistant sublayer, a corrosion-resistant layer and an interface agent layer from the outside of the outer wall of the flue to the inside. Filler is fully filled into the expansion joint between the outer walls of the flue wrapped with the base layers, two polytetrafluoroethene films are arranged on the filler, and a foam glass brick deck is adhered onto the two polytetrafluoroethene films. Permeation and corrosion of acid liquid can be avoided by means of the multilayer filling and corrosion-resistant layers. Further, the assembled foam glass bricks can well protect the joint filler and also ingeniously maintain functions of the expansion joint.
Description
[technical field]
The utility model relates to the anti-corrosion structure of chimney, relates in particular to the corrosion-resistant structure at place, chimney expansion joint.
[background technology]
Large-scale chimney is used for the discharging of combustion fumes, because the flue dust burning can produce a lot of dusts, and because burning produces sulfide, sulfide forms the acid solution in the chimney, corrode chimney easily, particularly the chimney of brick structure has the expansion joint usually, be used to exempt chimney stack and expand with heat and contract with cold and cause structural deterioration, because when the smoke stack emission flue gas, temperature is higher, and in case when quitting work, can drop to normal temperature, at this moment form the very big temperature difference that is subjected to, brick structure does not have good ductility, need to keep the expansion joint of the remaining of expanding with heat and contract with cold, regulate the distortion of expanding with heat and contract with cold.So, how effectively to avoid the expansion joint to be subjected to acid accumulator penetration for the chimney of brick structure, erode to chimney body and destroy, be a technical problem that needs to be resolved hurrily.
[summary of the invention]
The utility model is at above problem, proposed a kind of the utility structure of composite anti-corrosive to be made at (chimney, flue) expansion joint.
The technical solution of the utility model is: a kind of corrosion-resistant chimney, comprise the expansion joint between chimney, flue and the flue outer wall, it is characterized in that, be enclosed with three layers of prime coat on the part that both sides, described expansion joint are available by foam glass brick, from the flue outer wall be successively: flexible acid-resistant anti-corrosion putty layer, anticorrosive coat and interfacial agents layer toward interior.In described expansion joint of having wrapped up between the prime coat flue outer wall, filled up filler, on filler, two-layer polytetrafluoroethylene film is arranged, on two-layer polytetrafluoroethylene film, be adhesive with one deck foam glass brick.
Bottommost at the expansion joint has one deck stainless steel protection cover, as last antiseep barrier.
Described three layers of prime coat extend to the part that is covered by foam glass brick from the expansion joint between the flue outer wall, comprising anticorrosive coat thickness be not less than 1.2mm.
Described filler has three layers, and middle one deck is a flax silk, and the upper and lower all are elastic gums, and the thickness of described elastic gum is greater than 50mm.
Described two-layer polytetrafluoroethylene film is pasted according to level by elastic gum respectively, and described stickup is not less than 2mm with elastic gum thickness, and described polytetrafluoroethylene film width surpasses the expansion joint, and the width that surpasses is greater than 600mm.
The beneficial effects of the utility model are: utilize multi-level filling and anticorrosive coat, can avoid the infiltration and the corrosion of acid solution, the splicing of foam glass brick can not only be played good protection to chimney, flue in addition, and the ingenious effect of keeping the expansion joint.

Fig. 1 is the utility model one example structure schematic diagram.
Wherein: 1, flue outer wall; 2, expansion joint, 3, first foam glass brick; 4, stainless steel protection cover; 5, second foam glass brick; 6, flexible acid-resistant anti-corrosion putty layer; 7, anticorrosive coat; 8, interfacial agents layer; 9, the first road polytetrafluoroethylene film; 10, the second road polytetrafluoroethylene film; 11, flax silk; 12, elastic gum.
[specific embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.
Embodiment 1: a kind of corrosion-resistant chimney, comprise the expansion joint 2 between chimney, flue and the flue outer wall 1.It is characterized in that, be enclosed with three layers of prime coat on the part that the flue outer wall 1 of 2 both sides, described expansion joint is available by first foam glass brick 3, from the flue outer wall 1 toward interior be successively: flexible acid-resistant anti-corrosion putty layer 6, anticorrosive coat 7 and interfacial agents layer 8 have the filler that fills up expansion joint 2 between the described flue outer wall 1 that has wrapped up prime coat.The flax silk 11 in the middle of filler refers to and the elastic gum 12 of its both sides.On filler, have two-layer polytetrafluoroethylene film, be respectively the first road polytetrafluoroethylene film 9 and the second road polytetrafluoroethylene film 10, on two-layer polytetrafluoroethylene film, be pasted with one deck second foam glass brick 5.
2 bottommost has one deck stainless steel protection cover 4 at the expansion joint, as the protection barrier of flue outer wall outer surface.
Described three layers of prime coat extend to the part that is covered by first foam glass brick 3 from the expansion joint 2 of flue outer wall 1, comprising anticorrosive coat 7 thickness be not less than 1.2mm.
Described filler has three layers, and middle one deck is a flax silk 11, and the upper and lower all are elastic gums 12, and the thickness of described elastic gum 12 is greater than 50mm.
Described two-layer polytetrafluoroethylene film is pasted according to level by elastic gum 12 respectively, and described stickup is not less than 2mm with elastic gum thickness, and described polytetrafluoroethylene film width surpasses expansion joint 2, and the width that surpasses is greater than 600mm.Earlier use one deck elastic gum, paste the first road polytetrafluoroethylene film 9, paste one deck elastic gum again, paste the last second road polytetrafluoroethylene film 10 again.
The beneficial effects of the utility model are: utilize multi-level filling and anticorrosive coat, can avoid the infiltration and the corrosion of acid solution.The splicing of foam glass brick can not only be played good protection to chimney flue main body in addition, and the ingenious effect of keeping the expansion joint.
