Abstract
The utility model discloses a smoke-gathering combined pipe of a regenerator, and relates to the field of petrochemical engineering. The smoke-gathering combined pipe of the regenerator is characterized in that a layer of heat-resisting lining is attached to the inner surface of the pipe, a layer of abrasion-resisting lining is attached to the outer side of the heat-resisting lining, and the abrasion-resisting lining and the heat-resisting lining are connected through star-shaped annular anchoring nails. The arrangement longitudinal direction of the star-shaped annular anchoring nails is parallel with the axis of the pipe, the distance between every two star-shaped annular anchoring nails is the same, and any three star-shaped annular anchoring nails are arranged in an equilateral triangle mode. The smoke-gathering combined pipe of the regenerator has heat-insulating and abrasion-resisting performance, and is firmer in structure and better in stability.
Description
Technical field
The utility model belongs to petrochemical industry, relates generally to a kind of flue gas set composite pipe for regenerator.
Background technique
In refinery catalytic cracking unit, some are used for processing containing the equipment of high temperature catalyst particle, as the composite pipe that the flue gas set at regenerator top is used, heat insulation and wear-resisting for it, the lining that needs various heat insulation, the high-abrasive materials of auxiliary lining and skeleton to form.In existing lining structure, conventionally adopt cylindricality holdfast, end plate, hexsteel, holdfast is welded on the internal surface of equipment, and end plate is welded in the top of cylindricality, after insulated lining construction, hexsteel and end plate is welded again, and in hexsteel sky, pours into a mould high-abrasive material.Although this lining structure has certain anti-pressure ability, steadiness is poor, especially, under high-temperature condition, easily causes hexsteel cracking, thereby causes lining spalling.
Summary of the invention
The problem existing for prior art, the utility model provides a kind of good stability, firm in structure, has the New Regenerator flue gas set composite pipe of heat insulation and wear resistance performance.
For achieving the above object, the utility model adopts following technological scheme:
A kind of regenerator flue gas set composite pipe, inner surface of pipeline is with one deck heat-resistant lining, and described heat-resistant lining outside is with one deck wear resistance lining, and described wear resistance lining is connected by star annular anchor nails with heat-resistant lining.
Even more important, for making heat insulation and wear resistance dual-layer lining structure more firm, described star annular anchor nails is arranged longitudinally parallel with conduit axis, and distance equates between any two, and any three stars annular anchor nails is triangular arranged.
Further, described star annular anchor nails between any two distance be 120 ± 5mm.
Further, the thickness of described heat-resistant lining is 100-150mm, and the thickness of described wear resistance lining is 20 ± 2mm.
Further, the number of described star annular anchor nails is 255-6500.
Further, described heat-resistant lining is LC4 aluminium sheet.
Further, described wear resistance lining is LB2 lead bronze.
The beneficial effects of the utility model are: the utlity model has heat insulation and wear resistance performance, utilize star annular anchor nails to be fixedly connected with, single unit system structure is firmer, and stability is better.
Brief description of the drawings
Fig. 1 the utility model lining structure schematic diagram;
Fig. 2 star annular anchor nails arrange diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done further and explained.
This model utility regenerator flue gas set composite pipe as shown in Figure 1, inner surface of pipeline is with the heat-resistant lining 1 of one deck LC4 aluminium sheet, heat-resistant lining outside is with the wear resistance lining 2 of one deck LB2 lead bronze, and wherein the thickness of heat-resistant lining is 100mm, and the thickness of wear resistance lining is 20 ± 2mm.Wear resistance lining is connected by star annular anchor nails 3 with heat-resistant lining.
As shown in Figure 2, in use, star annular anchor nails 3 is arranged longitudinally parallel with conduit axis, and distance equates between any two, is about 120mm, and the annular anchor nails of any three stars is triangular arranged.So just form latticed skeleton, in the grid then lining castable ramming being formed in anchor nails, internal layer is insulated lining, and skin is wear resistance lining, thereby makes heat insulation and wear resistance dual-layer lining become as a whole.Wherein, in the time that the thickness of heat-resistant lining is 100mm, select approximately 255 star annular anchor nails to be fixedly connected with; In the time that the thickness of heat-resistant lining is 150mm, select approximately 6500 star annular anchor nails to be fixedly connected with, ensure that single unit system is firmer, stability is better.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
