The utility model discloses an evenly add mekralon in traditional wear -resistant liner pouring material, at the in -process that constantly heaies up, the fibre melts, leaves even slight passageway, is favorable to vapor to be discharged, has reduced and has poured into a mould internal steam pressure, and the antiknock fragility that can effectively improve the material can, improved wear -resistant material's microstructure simultaneously, improved the thermal shock resistance of material, be applied to in fluidized bed reactor and the cyclone trade.
Description
Technical field
The utility model relates to the cyclone separator cylinder of a kind of band polypropylene fibre wear resistance lining in fluidized-bed reactor and cyclone separator industry.
Background technology
At present, along with economic development, in petrochemical industry and the fluidized-bed reactor of Coal Chemical Industry and cyclone separator, owing to catalyst granules is serious to the abrasion of equipment and erosion, it is usually chosen in these device interiors and is easily worn or the position of erosion is lined with high abrasion lining.But in reactor running, being required to start and stop every year for several times, each start and stop high-abrasive material is all subject to the strongest thermal shock.The drastically change of temperature resisted by refractory material and non-destructive ability is referred to as thermal shock resistance.If wear resistance lining thermal shock resistance is poor, then the material that thermal shock causes peels off the lethal factor by becoming its damage.Chinese patent ZL00253425.8 discloses the wear resistance lining of a kind of catalytic cracking oil refining apparatus, it includes steel shell, insulated lining, and feature is: be provided with one layer of prefabricated wear resistance lining of alumina porcelain along the combination of insulated lining pin-connected panel inside reactor on insulated lining.This is novel has the washing away of high temperature resistant oil and gas, change the features such as convenience, applied range.But it in use can occur surface slabbing to peel off and cause device serious wear, unplanned parking.Therefore, the cyclone separator cylinder developing a kind of band polypropylene fibre wear resistance lining is always new problem anxious to be resolved.
Summary of the invention
The purpose of this utility model is to provide the cyclone separator cylinder of a kind of band polypropylene fibre wear resistance lining, this utility model is poor for high abrasion lining in use thermal shock resistance in prior art, come off the problem causing the life-span not grown, in fluidized-bed reactor and cyclone separator, solve the thermal shock resistance problems such as causing life-span length that comes off poor, easy to wear that existing high-abrasive material exists.
The purpose of this utility model is achieved in that the cyclone separator cylinder of a kind of band polypropylene fibre wear resistance lining, including cylinder outer steel shell, metal hexsteel, polypropylene fibre wear resistance lining, metal hexsteel is set in cylinder outer steel shell, polypropylene fibre wear resistance lining is set in the middle of two metal hexsteels；
Described polypropylene fibre abrasion-resisting lining material uses a kind of explosion-proof polypropylene fibre, a diameter of 25-40 μm, a length of 3mm.
The structure being characterized by it of the present utility model.Its operation principle is, a kind of wear resistance lining Han polypropylene fibre, has excellent microstructure and thermal shock resistance.By the introducing of polypropylene fibre, reach to change high-abrasive material air vent aperture size, distribution and the purpose of shape, the thermal expansion of effective padded coaming, the problem solving tradition wear resistance lining thermal shock resistance difference.This contains polypropylene fibre high-abrasive material and can be used in fluidized-bed reactor and cyclone separator, solves the problem causing the life-span not grown that comes off easy to wear that existing high-abrasive material exists.
The cyclone separator cylinder of a kind of band polypropylene fibre wear resistance lining is compared with prior art, have and uniformly add polypropylene fibre in tradition wear resistance lining castable, during constantly heating up, fiber fusion, leave uniform fine channel, be conducive to steam to discharge, reduce the steam pressure in pour mass, the anti-spalling of material can be effectively improved；Improve the microstructure of high-abrasive material simultaneously, the advantage such as thermal shock resistance improving material, will be widely used in fluidized-bed reactor and cyclone separator industry.

Detailed description of the invention
With detailed description of the invention, the utility model is further described below in conjunction with the accompanying drawings, but the drawings and specific embodiments are not limiting as scope of the present utility model.
Referring to the drawings, a kind of cyclone separator cylinder of band polypropylene fibre wear resistance lining, including cylinder outer steel shell 1, metal hexsteel 2, polypropylene fibre wear resistance lining 3, metal hexsteel 2 is set in cylinder outer steel shell 1, polypropylene fibre wear resistance lining 3 is set in the middle of two metal hexsteels 2.
Described polypropylene fibre wear resistance lining 3 material uses a kind of explosion-proof polypropylene fibre, a diameter of 25-40 μm, a length of 3mm.
It is described in further detail the utility model below in conjunction with embodiment:
Experimental result one, the primary raw material of polypropylene fibre wear resistance lining is electric smelting dense alumina, adds polypropylene fibre 0.2%wt on the basis of its basic recipe.Vibration moulding is the sample of 160mm × 40mm × 40mm in a mold, and maintenance under room temperature 48 hours, 110 after the demouldingOC dries 24h, then 1500OC calcines 3 hours, calculates permanent line rate of change after burning, and measures bulk density, cold crushing strength and strength at normal temperature.
Experimental result two, the primary raw material of polypropylene fibre wear resistance lining is electric smelting dense alumina, adds modified graphite 1%wt on the basis of its basic recipe.Vibration moulding is the sample of 160mm × 40mm × 40mm in a mold, and maintenance under room temperature 48 hours, 110 after the demouldingOC dries 24h, then 1500OC calcines 3 hours, calculates permanent line rate of change after burning, and measures bulk density, cold crushing strength and strength at normal temperature.
Comprehensive Experiment result one and experimental result two, the wear-resistant material casting material mobility containing polypropylene fibre has almost no change, and bulk density is declined slightly, and after burning, permanent line rate of change is obviously reduced, and strength at normal temperature significantly improves, and illustrates that thermal shock resistance is greatly improved.
