Abstract
The utility model discloses a compound anti-corrosion, abrasion-resistant and high-temperature-resistant pipeline. The compound anti-corrosion, abrasion-resistant and high-temperature-resistant pipeline is characterize din that a lining of a polytetrafluoroethylene plate (2) is arranged inside a steel shell (1) of the pipeline, a silicon carbide ceramic lining (4) is further lined in the polytetrafluoroethylene plate (2), a gap (3) is formed between the polytetrafluoroethylene plate (2) and the silicon carbide ceramic lining (4), and cement gum (5) is filled in the gap. The compound anti-corrosion, abrasion-resistant and high-temperature-resistant pipeline has the advantages that the linings are hydrochloric-acid-resistant, abrasion-resistant, high-temperature-resistant, chilling-resistant and quick-heating-resistant, a sealing protective layer is leakage-proof and heat-insulation, stress can be absorbed, accordingly, the pipeline is excellent in impact resistance and heat resistance, the steel shell is ultimately protected by polytetrafluoroethylene, and the pipeline in the design can be used for a long time under the condition of flowing scouring and corrosion of materials containing hydrochloric acid at high temperatures.
Description
Technical field
The utility model belongs to chemical metallurgy tube equipment, especially salt acid system alumina producing pipeline configuration technical field.
Background technique
At present, salt acid system alumina production pipeline, the anticorrosion antiwear structure of its use is in steel outer tube inner liner polytetrafluoroethylene or lining glass-lined.Lining teflon pipeline can meet the demands at low temperatures, but under high temperature (more than 100 ℃) because its expansion coefficient is large, hot mastication and aging in addition, under the direct erosive wear effect of material, cannot meet production requirement the working life of tetrafluoro layer; In fact glass lining pipe road cannot meet demand of industrial production.Because of its not resistance to rapid heat cycle, not shock-resistant, easily cracked, affect it and use, especially glass bushing pipe cannot be done and do greatly length, thereby cannot commercial Application.
Summary of the invention
Defect and deficiency that the purpose of this utility model structurally exists in order to overcome above-mentioned salt acid system alumina production pipeline just, and provide a kind of salt tolerant sour, wear-resistant, shock-resistant, high temperature resistant, resistance to rapid heat cycle, long service life, and can meet the composite anti-corrosive Wear-resistant, high-temperature resistant pipeline that industrial production is applied.
The utility model adopts following technological scheme to realize.
A kind of composite anti-corrosive Wear-resistant, high-temperature resistant pipeline, the utility model is provided with one deck polyfluortetraethylene plate lining in pipeline steel housings, in polyfluortetraethylene plate, be lined with again one deck silicon carbide ceramics lining, between polyfluortetraethylene plate and silicon carbide ceramics lining, be provided with in ， gap, gap and be filled with clay.
The utility model polyfluortetraethylene plate, with flange, turns over to pipe ends flange plate.
Ceramic lining of the present utility model (as silicon carbide lining) adopts segmentation to fire, and by acidproof, heatproof, lute in is bonding to be integral.
The beneficial effects of the utility model are: multiple-anticorrosion protective layer is acidproof, be rapid heat cycle, non-leakage; Ceramic-lined wear-resistant, long service life; Teflon lining is not subject to material erosive wear, has again packed layer protection, and good heat-insulation effect, serviceability temperature are high, and the life-span is long.
Below in conjunction with drawings and Examples, further set forth the utility model content.
Accompanying drawing explanation
Fig. 1 is the utility model structure and longitudinal partial schematic sectional view.
In figure: steel casing (1), polyfluortetraethylene plate (2), gap (3), silicon carbide ceramics lining (4), clay (5), flange plate (6), flange (7).
Embodiment
As shown in Figure 1, a kind of composite anti-corrosive Wear-resistant, high-temperature resistant pipeline, for salt acid system alumina producing.
A kind of composite anti-corrosive Wear-resistant, high-temperature resistant pipeline, the utility model is provided with one deck polyfluortetraethylene plate 2 linings in pipeline steel casing 1 the inside, in polyfluortetraethylene plate 2, be lined with again one deck silicon carbide ceramics lining 4, between polyfluortetraethylene plate 2 and silicon carbide ceramics lining 4, be provided with in 3 ， gaps, gap and be filled with clay 5.
The utility model polyfluortetraethylene plate 2, with flange 7, turns over to pipe ends flange plate 6.
4 segmentations of the utility model silicon carbide ceramics lining are fired, and with acid-resistant and heat-resistant lute in is bonding, are integral.
Silicon carbide ceramics lining 4 acid-resistant and heat-resistants are wear-resistant, can long-term work under hydrochloric material erosive wear and corrosion.Both made silicon carbide ceramics lining 4 occur seepage, because of the existence of polyfluortetraethylene plate 2, pipeline still can work.
The resistance to rapid heat cycle of silicon carbide ceramics lining 4, more shock-resistant than glass-lined.Between silicon carbide ceramics lining 4 and polyfluortetraethylene plate 2, fill clay 5 effectively various thermal stress and the impact stress of extraction duct, improve the working life of silicon carbide ceramics lining 4.The operating temperature that can also reduce polyfluortetraethylene plate 2 simultaneously, extends its working life.
Be the working life of silicon carbide ceramics lining 4 working life of the composite anti-corrosive Wear-resistant, high-temperature resistant pipeline that the utility model example is made, and adds the working life of clay 5, adds the summation in the working life of polyfluortetraethylene plate 2.Be long visible its working life.
Claims (2)
1. a composite anti-corrosive Wear-resistant, high-temperature resistant pipeline, it is characterized in that: in pipeline steel casing (1) the inside, be provided with one deck polyfluortetraethylene plate (2) lining, in polyfluortetraethylene plate (2), be lined with again one deck silicon carbide ceramics lining (4), between polyfluortetraethylene plate (2) and silicon carbide ceramics lining (4), be provided with in ， gap, gap (3) and be filled with clay (5).
As claimed in claim 1 and a kind of composite anti-corrosive Wear-resistant, high-temperature resistant pipeline, it is characterized in that: polyfluortetraethylene plate (2), with flange (7), turns over to pipe ends flange plate (6).
