Abstract
An anti-corrosion non-metallic expansion joint relates to the flue gas desulfurization unit gas channel comprises a nut (1), an ear plate (2), a double-headed bolt (3), an anti-corrosion ring band (4), a pressure plate (5), a compaction bolt (6), a waterproof dust prevention pillow (7), a supporting frame (9), a guide shell (10) and an anti-corrosion layer (11). The non-metallic expansion joint is able to tolerate different corrosion under the circumstances of different temperature and humidity, which is abrasion resistant, waterproof, dustproof with the advantages of excellent sealing performance, simple structure, low costs, easy installation and maintenance.
Description
Technical field
The utility model relates to a kind of flue gas desulfur device flue corrosion resistant non-metal expansion joint.
Background technique
Along with the progressively enforcement of national sustainable development strategy, will be more and more higher to the requirement of atmospheric environment protection, SO such as thermal power plant, Iron And Steel Plant, cement plant, chemical plant
2Pollution sources will progressively obtain keypoint treatment; Above-mentioned SO is administered in dry method, semidry method, wet desulphurization
2The important method commonly used of pollution sources.
Discharge flue in the dirty flue gas introducing of desulfurizer and the clean flue gas, because the thermal walking that exists temperature variation to produce is the problem that must solve in the engineering, the most frequently used method is to absorb the thermal expansion displacement with expansion joint.
Contain a large amount of SO in the handled flue gas of desulfurizer
2, SO
3, acidic materials and ash such as HCL, HF, in processing procedure, lower the temperature again and spray water-containing materials, thereby form the sour corrosion to each position of flue, and follow the wearing and tearing of gas-solid biphase flow body to flue, common expansion joint can't satisfy the usage requirement of desulfurizer at all.
Though corresponding expansion joint is arranged abroad, all has some defectives:
1, expansion of metal joint, its bellows and structural member are all used the antifriction metal (AFM) manufacturing, cost height, difficult processing
Degree is big, and domestic can't self-produced raw material, have only several companies such as the Germany and the U.S. to make,
The cost height.
2, non-metal expansion joint, external like product mainly is a unreasonable structure, does not have anti-wear design,
But the ponding dust stratification is installed inconvenience, the purchasing of raw materials, and processing all is difficult to, and cost is also high in addition.
The model utility content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, a kind of various corrosion that can tolerate under different temperatures, the humidity situation are provided, wear-resistant, anti-ponding, accumulatingdust, good seal performance, compensation rate is big, maintenance for ease of maintenaince, the life-span is long, processes flue gas desulfur device flue corrosion resistant non-metal expansion joint simple, easy operating easy for installation.
For achieving the above object, composition of the present utility model is otic placode to be housed respectively constitute " TT " type structure on the symmetrical position of stud bolt two ends, two otic placode lower ends are separately fixed on the underframe of frame, the anticorrosion astragal that is characterized in water proof and dust proof pillow two ends is separately fixed on two supporting frames on frame both sides, and the flow direction along flue gas on the underframe of frame is equipped with the guide shell that its surface scribbles anticorrosive coat.
This non-metal expansion joint has overcome the deficiencies in the prior art, has realized the purpose of this utility model, and simple in structure, cost is low, installation and maintenance are advantage easily.
Description of drawings

Fig. 2, flue gas desulfur device flue corrosion resistant non-metal expansion joint scheme of installation
The label title of Fig. 1 and Fig. 2: 1, nut, 2, otic placode, 3, stud bolt, 4, anticorrosion astragal, 5, pressing plate, 6, hold-down bolt, 7, the water proof and dust proof pillow, 8, supporting frame, 9, underframe, 10, guide shell, 11, anticorrosive coat, 12, flue.
Embodiment:
In conjunction with above-mentioned accompanying drawing, narrate embodiment of the present utility model, two otic placodes 2 are installed in by nut 1 and constitute " TT " type structure on the stud bolt 3 two ends symmetrical positions, two otic placode 2 lower ends are separately fixed on the underframe 9 of frame, the anticorrosion astragal 4 that water proof and dust proof is rested the head on 7 two ends is separately fixed on two supporting frames 8 on frame both sides by pressing plate and with hold-down bolt 6, and the flow direction along flue gas on the underframe 9 of frame is equipped with the guide shell 10 that its surface scribbles anticorrosive coat 11.
The major function of above-mentioned guide shell 10 is to prevent that wearing and tearing and flue gas from impacting; The major function of water proof and dust proof pillow 7 is to prevent ponding, laying dust in the anticorrosion astragal, and plays function of heat insulation; The main effect of anticorrosion astragal 4 is sealings, absorbs thermal walking, and stud bolt 3 and otic placode 2 major functions are fixed expansion joint installation dimensions, and (annotate: after the installation, stud bolt should be to remove before using) also prevents the expansion joint distortion in transportation process.As shown in Figure 2, the utility model is installed in the flue 12 and uses.
Claims (1)
1, a kind of flue gas desulfur device flue corrosion resistant non-metal expansion joint, formation is that two otic placodes (2) are installed on the symmetrical position of stud bolt (3) two ends, two otic placodes (2) lower end is separately fixed on the underframe (9) of frame, the anticorrosion astragal (4) that it is characterized in that water proof and dust proof pillow (7) two ends is separately fixed on two supporting frames (8) on frame both sides, goes up at the underframe (9) of frame and along flue gas flow direction the guide shell (10) that its surface scribbles anticorrosive coat (11) is housed.
