Abstract

The utility model discloses a chimney, in particular to a chimney lining structure for high temperature made of insulating material. The structure is that the calcium silicate insulation layer (3) is connected to the inner wall of steel tube wall (4), the aluminum silicate fiberboard (2) is connected to the calcium silicate insulation layer (3), the high-intensity high wear-resistant casting clay layer (1) to the aluminum silicate fireboard (2). The utility model adopts the insulation structure of the high-intensity high wear-resistant casting clay layer (1), the aluminum silicate fiberboard (2) and the calcium silicate insulation layer (3) to meet the requirement of discharge of high temperature flue in 1000 to 1350 DEG C, and reduces amount of material and cost of the chimney.

Description

A kind of high temperature chimney lining structure
Technical field
The utility model relates to a kind of chimney, particularly relates to a kind of high temperature chimney lining structure that adopts heat-barrier material to make.
Technical background
The calcining petroleum coke flue-gas temperature is up to 1300 ℃, need pass through flue, the chimney high altitude discharge, adopt brick, armored concrete barrel, liner commonly used is to adopt heat-barrier material: refractory fireclay block masonry, diatomite, blast furnace granulated slag, expanded perlite etc. are made, and they all are difficult to adapt to 1300 ℃ high temperature requirement.Both just exempted to adopt by force above-mentioned material, and because consumption increases considerably, caused the significantly rising of investment, wind correspondingly, geological process also cause increasing of barrel material usage, and economic benefit reduces.
The utility model content
The utility model provides a kind of high temperature chimney lining structure, purpose exactly in order to solve the problems of the technologies described above be to improve the resistance to elevated temperatures of chimney, reduces material usage, reduces the cost of chimney.
To achieve these goals, the utility model is achieved in that a kind of high temperature chimney lining structure, and it is to be made of the calcium silicate heat-preserving layer that is connected with steel cylinder wall inwall, the alumina silicate fibre flaggy that is connected with the calcium silicate heat-preserving layer, the clay matter high-strength, high-anti-friction cast bed of material that is connected with the alumina silicate fibre flaggy.
Described steel cylinder wall inwall place is fixedly connected with a plurality of metal connecting pieces, and metal connecting piece passes the calcium silicate heat-preserving layer and the alumina silicate fibre flaggy is inserted in the clay matter high-strength, high-anti-friction cast bed of material, and metal connecting piece is the setting of plum blossom shape in the steel cylinder wall.
The thickness of the described clay matter high-strength, high-anti-friction cast bed of material 1 is 200-550mm.
The thickness of described alumina silicate fibre flaggy 2 is 50-80mm.
The thickness of described calcium silicate heat-preserving layer 3 is 75-100mm.
Advantage of the present utility model and effect are as follows:
The utility model adopts the heat insulation structural of establishing the clay matter high-strength, high-anti-friction cast bed of material, alumina silicate fibre flaggy, calcium silicate heat-preserving layer in the steel cylinder wall to make steel stack can satisfy the emission request of the high-temperature flue gas of 1000~1350 degree Celsius.The utility model has reduced material usage, has reduced the cost of high temperature chimney.
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, the clay matter high-strength, high-anti-friction cast bed of material; 2, alumina silicate fibre flaggy; 3, calcium silicate heat-preserving layer; 4, steel cylinder wall; 5, metal connecting piece.
The specific embodiment
As shown in Figure 1, the utility model structure is as follows: the calcium silicate heat-preserving layer 3 that is connected with steel cylinder wall 4 inwalls, the alumina silicate fibre flaggy 2 that is connected with calcium silicate heat-preserving layer 3, the clay matter high-strength, high-anti-friction that is connected with the alumina silicate fibre flaggy 2 cast bed of material 1.Steel cylinder wall 4 inwall places are fixedly connected with a plurality of metal connecting pieces 5, metal connecting piece 5 passes calcium silicate heat-preserving layer 3 and alumina silicate fibre flaggy 2 is inserted in the clay matter high-strength, high-anti-friction cast bed of material 1, and a plurality of metal connecting pieces 5 are the setting of plum blossom shape in steel cylinder wall 4.Calcium silicate heat-preserving layer 3 is to be built by laying bricks or stones by the calcium silicate heat-preserving piece to form.The thickness of the clay matter high-strength, high-anti-friction cast bed of material 1 is 200-550mm.The thickness of alumina silicate fibre flaggy 2 is 50-80mm.The thickness of calcium silicate heat-preserving layer 3 is 75-100mm.The model of the clay matter high-strength, high-anti-friction cast bed of material 1 material therefor is that DCL-45 clay matter high-strength, high-anti-friction waters material feeding.Metal connecting piece 5 adopts 1Cr25Ni20Si2,1Cr25Ni20 austenite stainless heat-resistance steel, should meet the GB/T1221 standard.
