3Heat insulating casting material thickness is that 80mm and no hexsteel wear-resistant castable thickness are 70mm, and lining material unit thickness thermal resistance value is 0.295M
2H ℃/kcal; And domesticly be used for catalyst cracker and the revivifier lining material is high-alumina cement, and its heat insulating casting material thickness is that 74mm and hexsteel wearing layer thickness are 26mm, its unit thickness thermal resistance value is 0.322M
2H ℃/kcal; Also have and only use individual layer thermofin lining material, its unit thickness thermal resistance value is 0.303M
2H ℃/kcal; Above-mentioned catalyst cracker and/or the revivifier lining material weak point of being used for is that the thermal resistance value of unit thickness is low, thereby causes the temperature drift of reactor and revivifier housing outer surface, and thermosteresis is bigger, and lining is short work-ing life.And the operational procedure complexity, existing lining construction is at catalyticreactor and/or revivifier inwall weldering bar for line; Rust cleaning; The coating thermofin; Maintenance; The weldering end plate; The moulding hexsteel; Hexsteel is installed; The coating wearing layer; Maintenance; Thermal treatment etc. are required long in time limit, the cost height.(specific thermal resistance value be benchmark with 100mm thickness)
The objective of the invention is in order to improve the thermal resistance value of lining material unit thickness, reduce the temperature of housing outer surface, reduce thermosteresis, save the energy, prolong lining work-ing life, simplify operational procedure, improve speed of application.Also reached the purpose that reduces cost simultaneously.
In order to improve the thermal resistance value of Thermal Equipment composite lining material unit thickness, the invention provides a kind of high thermal resistance heat insulation and wear resistance composite lining material that is applicable to catalyst cracker and/or revivifier, the thermal resistance value of its unit thickness is 0.686M
2H ℃/kcal.With reference to accompanying drawing 1, at first at catalyst cracker and/or revivifier inwall weldering metal heat preservation nail; Rust cleaning; Use binding agent that high heat rejection hot plate is attached on the inwall; The anti-water secluding agent of spraying; The spraying steel fiber strengthens wear-resistant material; Health; Intensification thermal treatment and form the heat insulation and wear resistance dual-layer lining.Wherein high thermal resistance calcium silicate board or aluminosilicate fiberboard be thermofin and steel fiber to strengthen wear-resistant material be wearing layer, it is that wear-resisting jetting material (coating) by the shape that looses adds water and forms through sprayed construction.The batching and the weight percent of wearing layer are composed as follows: high-alumina cement (quality meets the GB201-81 standard) consumption is with 5-20%; Refractory aggregate (comprise the calcining bauxitic clay, flint clay etc., granularity is 0～6mm) consumption 70～92%; Micro mist (chainotte for example, kaolin, the silicon ash, aluminum oxide etc., granularity is less than 60 microns, and optimum size is less than 1 micron, and consumption is 0～5%; Add material by steel fiber, defloculating agent, water reducer and water are formed, and it adds the material consumption is with above-mentioned high-alumina cement, and three kinds of weight of material sums of refractory aggregate and micro mist are absolutely, and the outer dosage of steel fiber (molten pulling out or cold drawn steel fiber) is 0-4%; The outer dosage of defloculating agent (alkali metal phosphate, alkali metal polysilicate alkali hydrochlorate) is 0～0.2%; The outer dosage of water reducer (naphthalenesulfonate condenses, lignosulfonic acid salt, paracyanogen acid amides etc.) is 0～0.1%.Outer amount of water is 7-11.4%.
The present invention is doubled than the unit thickness thermal resistance value of the lining material of existing catalyst cracker and/or revivifier, from 0.322M
2H ℃/kcal brings up to 0.686M
2H ℃/kcal, cause reactor and/or revivifier housing outer surface temperature-averaging to reduce by 21.5～28.8 ℃, reached the purpose of saving the energy, if by 23 ℃ of housing outer surface coolings, the reactor and the revivifier lining total area are by 2000 meters
2Measuring and calculating, savings heat be 793949.98 kilocalories/time, amount to and mark coal and can save 993.531 tons/year; The ultimate compression strength of lining material is doubled, from 200Kg/cm
2(20MPa) rise to 400Kg/cm
2(40MPa), the lining construction cost has reduced by 24%, from 1029.10 yuan/M
2Reduce to 781.13/M
2, simplified operational procedure, improve speed of application and save the duration 70%.
