Abstract
The utility model relates to a high temperature furnace gas pipeline, in particular to an anti-abrasive and self-insulation high temperature furnace gas pipeline. The anti-abrasive and self-insulation high temperature furnace gas pipeline aims to solve the problems that an anti-abrasive layer of an existing high temperature furnace gas pipeline falls off easily, maintenance is inconvenient, and the service life is short. The anti-abrasive and self-insulation high temperature furnace gas pipeline comprises an outer protective steel pipe, a heat insulation layer, an anti-abrasive layer and a plurality of limit blocks, wherein the outer protective steel pipe and the anti-abrasive layer are in a round pipe shape; the outer protective steel pipe and the heat insulation layer are installed on the outer side wall of the anti-abrasive layer in a sleeved mode in sequence from outside to inside; the limit blocks are evenly distributed between the outer side wall of the anti-abrasive layer and the inner side wall of the outer protective steel pipe. The anti-abrasive and self-insulation high temperature furnace gas pipeline is used for conveying high temperature furnace gas of industrial furnaces.
Description
Technical field
The utility model relates to a kind of high-temperature furnace smoke pipeline, is specifically related to a kind of wear-resisting self-heat conserving high-temperature furnace smoke pipeline.
Background technology
At present, the high-temperature furnace smoke pipeline on market roughly has following several version:
1. heatproof cast steel pipeline, this pipeline is to adopt the casting of nickel Chrome rare earth alloy, manufacture is installed all more convenient, but the manufacturing cost costliness of nickel Chrome rare earth alloy need to be incubated making at the scene, and its service life is shorter.
2. add the pipeline of package with cooling water, there is one deck castable refractory its innermost layer and flue gas contact site, then be that heatproof cast steel shell is stainless steel, cast steel and stainless steel casing form a folder package, water between cast steel and stainless steel by playing cooling effect, the advantage of this structure is can be without external thermal insulation, and can also utilize high-temperature flue gas by cool water heating, realizes reusing of energy source.Shortcoming is very difficult solution of expansion issues that composite is manufactured pipeline, and operation stability is poor, often occurs that wear-resistant castable comes off and pipeline break phenomenon, and this complex structure, maintain and replace inconvenience.
3. liner refractory casting pipe material, its version is that internal layer and hot cigarette contact position are castable, skin is heat-insulation layer, outermost layer is carbon steel, the advantage of this kind of structure be cost than above two kinds all low, and service life also than the length of above two kinds of versions, shortcoming is that the refractory casting bed of material has been grown there will be cracked coming off service time, maintenance is inconvenient, and the bad assurance of repair quality.
Utility model content
The utility model is to solve the wearing layer of existing high-temperature furnace smoke pipeline easily to occur obscission, and maintenance is inconvenient, service life short problem, and then a kind of wear-resisting self-heat conserving high-temperature furnace smoke pipeline is proposed.
The utility model is to address the above problem the technical scheme of taking to be: the wear-resisting self-heat conserving high-temperature furnace smoke pipeline of one described in the utility model comprises steel outer casing, heat-insulation layer, wearing layer and multiple limited block, described steel outer casing and wearing layer are tubular, steel outer casing and heat-insulation layer ecto-entad are sleeved on the lateral wall of wearing layer successively, between the lateral wall of wearing layer and the madial wall of steel outer casing, are laid with multiple limited blocks.
The beneficial effects of the utility model are: the silicon carbide ceramics entirety that wearing layer of the present utility model adopts is fired, silicon carbide ceramics is finer and close, stable chemical performance, intensity is large, hardness is high, and thering is good thermal shock resistance, antiacid caustic corrosion and non-oxidizability, in service not having comes off and cracked problem.Silicon carbide ceramics is reserved expansion clearance in the process of making, and can not cause damage to pipeline because of expansion issues.And by limited block being set between wearing layer and steel outer casing, guarantee that wearing layer and steel outer casing are in cold conditions and all can Concentric rotation when hot; The utility model convenient maintenance and replacement, and because silicon carbide ceramics has good antiwear heat resisting performance, the service life of having improved greatly pipeline.
