In the low-temperature corrosion protection such as desulfurization, wet dust removal flue, there is liquid sour water in flue inside, and non-metal expansion joint is except needs are corrosion-resistant, sealing requirements need reach 100%, existing common expansion joint sealing does not reach this requirement, easily produces sour water and leaks, corrosion lower part equipment.
In order to overcome the deficiencies in the prior art, people, through constantly exploring, have proposed various solutions, and as Chinese patent literature discloses a kind of non-metal expansion joint [patent No.: CN202203596U], it comprises joint, covering and packed layer; Its inner side is connected with flue exit, and described covering two ends connect respectively two described joint outsides; Between described joint and covering, packed layer is set.Such scheme has good flexibility, and equipment and system is affected without reaction thrust, brings great convenience to piping design, has also improved the Security of equipment and system; There is corrosion resistant effect simultaneously.But in the time that this scheme is used for low-temperature corrosion protection flue, because flue flange need to carry out phosphatization preservative treatment, therefore the surface of flue flange has phosphorus sheet and uneven, such scheme is difficult to be tightly connected with flue flange, therefore still can cause sour water to leak.
Model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of good airproof performance can prevent the low-temperature corrosion protection flue non-metal expansion joint that sour water leaks.
For achieving the above object, the utility model has adopted following technical proposal: a kind of low-temperature corrosion protection flue non-metal expansion joint, comprise two opposed Anti-corrosive smoke canal flanges, two Anti-corrosive smoke canal flanges connect respectively the first frame and the second frame, the projection interlaced and in vertical direction of the first frame and the second frame overlaps, the first described frame and the second frame are connected with Anti-corrosive smoke canal flange seal by sealing layer and fit in the surface of sealing layer and Anti-corrosive smoke canal flange, in the first frame and the second frame, be also provided with the covering being tightly connected with the first frame and the second frame, described covering bottom is also provided with a low spot floss hole.
In above-mentioned low-temperature corrosion protection flue non-metal expansion joint, described sealing layer is fluororubber pad.
In above-mentioned low-temperature corrosion protection flue non-metal expansion joint, described low spot floss hole is positioned at the bottommost of covering.
In above-mentioned low-temperature corrosion protection flue non-metal expansion joint, described low spot floss hole is provided with waste pipe and this waste pipe flange assembly is connected with covering is dismountable.
In above-mentioned low-temperature corrosion protection flue non-metal expansion joint, described waste pipe also connects fast interface, and waste pipe and fast interface are provided with outside thread, and the female swivel nut of tool and waste pipe and fast interface are spirally connected.
In above-mentioned low-temperature corrosion protection flue non-metal expansion joint, described covering outside is also provided with a retainer ring, and bolt fits tightly sealing layer and Anti-corrosive smoke canal flange after passing retainer ring, covering, sealing layer.
Compared with prior art, the utility model has the advantage of: convenient disassembly, good airproof performance, has corrosion protection and 100% effect sealing for low-temperature corrosion protection flue, can prevent that sour water from leaking, and plays a protective role to equipment.

In figure: the first frame 11, the second frame 12, sealing layer 20, covering 30, low spot floss hole 40, waste pipe 41, flange assembly 42, fast interface 43, swivel nut 44, retainer ring 50, bolt 60, Anti-corrosive smoke canal flange 100.
Arrow shown in Fig. 1 is the gas flow in low-temperature corrosion protection flue.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As Fig. 1, shown in Fig. 2, a kind of low-temperature corrosion protection flue non-metal expansion joint, comprise two opposed Anti-corrosive smoke canal flanges 100, two Anti-corrosive smoke canal flanges 100 connect respectively the first frame 11 and the second frame 12, the projection interlaced and in vertical direction of the first frame 11 and the second frame 12 overlaps, the first described frame 11 and the second frame 12 are tightly connected by sealing layer 20 and Anti-corrosive smoke canal flange 100 and sealing layer 20 is fitted with the surface of Anti-corrosive smoke canal flange 100, in the first frame 11 and the second frame 12, be also provided with the covering 30 being tightly connected with the first frame 11 and the second frame 12, described covering 30 bottoms are also provided with a low spot floss hole 40.
Because Anti-corrosive smoke canal flange 100 surfaces scribble the phosphorus sheet of anticorrosion use, therefore surface smoothness is inadequate, there will be uneven phenomenon, the effect of sealing layer 20 is exactly that the Anti-corrosive smoke canal flange 100 of surface irregularity and the first frame 11 and the second frame 12 are tightly connected, prevent that sour water leaks the situation of corrosion lower part equipment, plays the effect of 100% sealing.Low spot floss hole 40 can discharge sour water, causes leakage in order to avoid the too much hydraulic pressure of ponding is excessive.
Frame 10 is metal material, covering 30 is non-metallic material, adopts silicone rubber or high silica teflon and alkali-free glass silk floss MULTILAYER COMPOSITE to form, and sealing layer 20 is fluororubber pad, and fluororubber pad is soft gasket, there is anticorrosion and seal action preferably.
Low spot floss hole 40 is positioned at the bottommost of covering 30.In addition, low spot floss hole 40 is provided with waste pipe 41 and this waste pipe 41 use flange assemblies 42 are connected with covering 30 is dismountable.Waste pipe 41 also connects fast interface 43, and waste pipe 41 and fast interface 43 are provided with outside thread, and the female swivel nut 44 of tool is spirally connected with waste pipe 41 and fast interface 43.Low spot floss hole 40 is arranged on the bottommost of covering 30, in the lowest part of covering 30, therefore can thoroughly drain the sour water of expansion joint inside.
For sealing layer 20 and Anti-corrosive smoke canal flange 100 are fitted tightly, covering 30 outsides are also provided with a retainer ring 50, and bolt 60 fits tightly sealing layer 20 and Anti-corrosive smoke canal flange 100 after passing retainer ring 50, covering 30, sealing layer 20.
The utility model, convenient disassembly, good airproof performance, has the corrosion of putting and 100% effect sealing for low-temperature corrosion protection flue, can prevent that sour water from leaking, and plays a protective role to equipment.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although more used the terms such as the first frame 11, the second frame 12, sealing layer 20, covering 30, low spot floss hole 40, waste pipe 41, flange assembly 42, fast interface 43, swivel nut 44, retainer ring 50, bolt 60, Anti-corrosive smoke canal flange 100 herein, do not got rid of the possibility that uses other term.Use these terms to be only used to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
