Abstract
The invention discloses a wear-resistant lining, which is used for solving the problems of reduction in particle size separating efficiency, crushing of large-particle catalysts and the like caused by flaky stripping on the surface of the conventional high-wear-resistance lining in a use process. The wear-resistant lining is mainly characterized in that: metal fibers and/or explosion-proof fibers are uniformly distributed in a high-wear-resistance single-layer lining; the metal fibers are phi0.05-0.1 millimeter in diameters, and are 5-15 millimeters in total length L; and the metal fibers can be bent upwards, rightwards, backwards and rightwards at 90 degrees in sequence from one end for four times, so that a structure consisting of five parts is formed. The wear-resistant lining can be applied to a reactor or a regenerator in a fluidizaton reaction regeneration device, and is taken as a high-performance wear-resistant lining inside a cyclone separator at a position where wear is caused by high air speed and erosion is severe.
Description
Technical field
The present invention relates to a kind of wear resistance lining, be mainly used in the reactor or regenerator in the fluidization reaction regeneration device, cause wearing and tearing and the high-performance of serious position of erosion such as the cyclone separator inside lining that resistance to wears as gas speed is higher.
Background technology
In the reactor or regenerator of the fluidization reaction regeneration device of petrochemical industry and Coal Chemical Industry, cause some positions wearing and tearing of these equipment and erosion is serious as cyclone separator inside because the gas of catalyst speed is higher.For the wearing and tearing and the erosion at some positions of preventing these equipment, usually in the inside of these equipment or outsidely be prone to be worn or the position lining of erosion is made the high abrasion single-layer lining of anchoring piece than high-wear resistance with hexsteel to have; But through after the shutting down several times, the surface of hexsteel high abrasion single-layer lining tends to slabbing and peels off; Scale off the layer the about 3mm of thickness about; Become the shape of hexagon tortoise plastron mesh, the sheet high abrasion single-layer lining that comes off is prone to result in blockage what is more important to installing narrow and small position; Smooth or slick and sly excessive like the high abrasion single-layer lining surface requirements of cyclone separator inside; After the local slabbing of high abrasion liner surface peels off, just caused the inner high abrasion single-layer lining surface irregularity of cyclone separator, lean on the separative efficiency of the high velocity air that contains catalyst of rotating centrifugal separation to reduce; Particularly the grade separative efficiency of large granular catalyst more is prone to reduce; Simultaneously, also be prone to make large granular catalyst broken, increase the losing quantity of catalyst.
Chinese patent ZL 00253425.8 discloses a kind of wear resistance lining of catalytic cracking oil refining apparatus; It includes steel shell, insulated lining, and characteristics are: the inboard insulated lining of reactor is provided with the alumina porcelain prefabricated wear resistance lining of one deck along the combination of insulated lining pin-connected panel.The present invention is owing to adopt alumina porcelain to do the wear resistance lining of catalytic cracking oil refining apparatus, thereby reduces cost, and improved 3 times service life, without maintenance, need not set off by contrast; If there is the alumina porcelain wear resistance lining artificially to damage, monolithic is changed and is got final product, normal temperature to 1000 ℃ no residual stress distortion.This is novel also have oil resistant vapour wash away, change characteristics such as convenience, applied range.But the reduction of grade separative efficiency, large granular catalyst fragmentation that surperficial slabbing peeled off and caused large granular catalyst in use can take place in it.
The main cause that causes the surperficial slabbing of high abrasion single-layer lining to peel off has following 2 points:
1. the intensity of high abrasion single-layer lining is very high; Be friable structure, linear shrinkage ratio own is bigger, when the lining ambient temperature changes too soon; High abrasion single-layer lining inside and hull-skin temperature are different; Be that liner and outer surface exist different deflections, under the effect of stress, cause high abrasion single-layer lining outside to separate with inside.
2. the bulk density of high abrasion single-layer lining is bigger; Inside, the top layer spilehole of remaining silent is more, and when the lining ambient temperature changed, the volume of the spilehole of remaining silent will expand or shrink; The gas that expands will make the inner local stress that produces of high abrasion single-layer lining; Cause the generation of crackle, after the operation of several shutting down, crackle expansion and make high abrasion single-layer lining surface layer peeling.
Summary of the invention
The present invention be directed to that high abrasion lining in the prior art can take place in use that surperficial slabbing peels off and the shortcoming such as the reduction of grade separative efficiency, large granular catalyst fragmentation that causes large granular catalyst, and a kind of wear resistance lining is provided.
Technical scheme of the present invention is: a kind of wear resistance lining; Comprise hexsteel and high abrasion single-layer lining; It is characterized in that: even distribution metallic fiber and/or explosion-proof fiber in the high abrasion single-layer lining, the diameter of said metallic fiber is Φ 0.05～0.1mm, total length L is 5～15mm.
The further technical characterictic of the present invention is: even distribution metallic fiber and explosion-proof fiber in the said high abrasion single-layer lining.
The further technical characterictic of the present invention is: the metallic fiber amount in the said high abrasion single-layer lining is 20～25Kg, and explosion-proof fibre weight is 0.5～1.5Kg, in every cubic metre of high abrasion concrete lining material.
The further technical characterictic of the present invention is: said metallic fiber is the bending that makes progress, becomes for 4 times, backward, again 90 degree from an end successively to the right to the right, forms the structure of being made up of 5 parts.
The further technical characterictic of the present invention is: the length L 1 of said metallic fiber first is 1～3mm, and second portion and tetrameric length L 3 are respectively 1～2mm, and the length L 2 of third part is 3～9mm.
The further technical characterictic of the present invention is: the diameter of said explosion-proof fiber is 40～100 μ m, length 10～15mm, and the carbonization point is 150 ± 10 ℃.
Wear resistance lining of the present invention can be used in the reactor or regenerator in the fluidization reaction regeneration device, causes wearing and tearing and the high-performance of serious position of erosion such as the cyclone separator inside lining that resistance to wears as gas speed is higher.
The advantage that the present invention compared with prior art has is: the present invention increases metallic fiber in high abrasion single-layer lining concrete; At first it can increase the globality of high abrasion single-layer lining and the generation that tensile strength reduces crackle; Secondly metallic fiber can carry out the heat conduction faster, makes high abrasion single-layer lining internal and external temperature consistent as far as possible; In high abrasion single-layer lining concrete, increase explosion-proof fiber; It mainly is explosion-proof fiber high temperature carbonization; Be equivalent to form many tiny passages; The high abrasion single-layer lining inside spilehole of remaining silent is communicated with external environment condition, thus the inner local stress that produces of high abrasion single-layer lining that the volumetric expansion of the spilehole of remaining silent when avoiding ambient temperature to raise causes.
