Abstract
The utility model relates to a wear-resistance lining of catalytic cracking reactor, which comprises a steel shell and a heat insulated lining. The utility model is characterized in that a high aluminum porcelain prefabricating wear-resistance lining which combined in a split mounting mode along the heat insulated lining and is arranged on the heat insulated lining arranged in the inner side of the reactor. Due to the adoption of high aluminum porcelain which can be used as the wear-resistance lining of a catalytic cracking refinery device, and consequently, cost can be reduced, service life can be increased by three times, and the utility model has no need to maintenance and foil. If the high aluminum porcelain wear-resistance lining is artificially damaged, a single block of the high aluminum porcelain wear-resistance lining can be exchanged, and the utility model can not be deformed without residual stresses from a normal temperature to 1000 DEG. The utility model has the characteristics that high temperature fuel-oil erosion resistance, convenient replacement, etc.
Description
The utility model belongs to catalytic cracking oil refining apparatus technical field, specifically a kind of improvement to catalyst cracker and revivifier lining.
In the catalytic cracking reaction device, catalyst cracker (settling vessel) and catalytic cracking regenerator (comprise and burn jar) are one of topmost devices.Its housing of present catalyst cracker and revivifier all adopts cold wall design, steel shell, the main raw of interior insulated lining has luminite cement, high-alumina cement, haydite vermiculite luminite cement, light-weight heat-insulating concrete, the hard calcium silicate board with microporous of no silk flosssilk wadding, hexsteel heat-resistant lining and macrobead pearlstone etc., and to use with macrobead pearlstone heat insulating concrete lining serve as maximum.And the wearing layer of revivifier mainly adopts materials such as high-alumina cement, bauxite clinker, alumina fine powder.Its manufacturing process mainly adopts manual ramming or stickup, and technology is quite complicated, labour intensity is big, and work-ing life is not high yet, and the waste of the energy is also bigger.Therefore above-mentioned traditional structure and material be the needs of incompatibility present stage oil catalytic cracking unit.
The purpose of this utility model provides low, the anti-wear resistance lining that washes away the catalytic cracking oil refining apparatus of a kind of cost.
The purpose of this utility model is achieved in that it includes steel shell, insulated lining, is characterized in that: the inboard insulated lining of catalytic cracking oil refining apparatus is provided with the alumina porcelain prefabricated wear resistance lining of one deck along the combination of insulated lining piecing assembly.
The utility model also is included in and also is provided with one deck stainless steel buffer zone between side insulated lining and the wear resistance lining.
The utility model is owing to adopt alumina porcelain to do the wear resistance lining of catalytic cracking oil refining apparatus, thereby equipment cost has been reduced about 30%, and improved 3 times work-ing 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 unrelieved stress distortion.This is novel also have rational in infrastructure, safe and reliable, oil resistant vapour wash away, change characteristics such as convenience, applied range.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is that reaction general ability of the present utility model is cutd open the structural representation sketch
Fig. 2 is that the A of Fig. 1 is to enlarged diagram
Shown in Fig. 1-2,1 among the figure is the revivifier of catalytic cracking unit, is steel shell 2 at the skin of revivifier 1, inwardly is disposed with the prefabricated wear-resisting lining nexine 5 of heat shield liner nexine 3, steel buffer zone 4 and alumina porcelain at catalytic regeneration device steel shell 2.Because the general employing of heat shield liner nexine is that software is filled, the steel buffer zone that can not constitute wear-resisting combination lining depends on wall setting (and when not having thermofin, be not provided with buffer zone need be set), the connection at steel buffer zone 4 two ends is to adopt holding bolt to connect, and the root a tree name needs and can also be formulated in length and breadth on the different sites: the prefabricated wear-resisting lining nexine 5 of alumina porcelain makes up along the insulated lining piecing assembly.
Claims (2)
1, a kind of wear resistance lining of catalyst cracker, it includes steel shell, insulated lining, it is characterized in that: 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 piecing assembly.
2, wear resistance lining according to claim 1 is characterized in that: be provided with one deck stainless steel buffer zone between inboard insulated lining of reactor and the wear resistance lining.
