Abstract

The utility model relates to a compound furnace wall of dilute-phase fluosolids roasting furnaces, which comprises a steel shell, rigid and light fireproof insulating bricks, an upshaped castable refractory layer and a heavy castable refractory layer. At least one metal anchorage is arranged in the compound furnace wall and connects rigid and light fireproof insulating bricks, a shapeless castable refractory layer and a heavy castable refractory layer and the steel shell into a whole. A piece 0f light insulating fibrofelt is arranged between the rigid and light fireproof insulating bricks and the steel shell. The metal anchorage is in V shape with a V-shaped head and the included angle between two anchorage walls in the front is more than 60 degrees. With novel and reasonable structure, long service life and low cost, the compound furnace wall of the utility model can be used for replacing and updating sold-style imported roasting furnaces in a reliable and safe way. The optimized design of the invention solves a series of industrial difficulties of the mechanics optional distribution of the skeleton structure of the shaped refractory, the distinction of different materials, and the dilatation inosculation, etc. the reasonable design of the multiple compound furnace wall of the dilute-phase fluosolids roasting furnaces can greatly improve the service life of the furnaces.

Description

The compound furnace wall of dilute phase fluidization roasting furnace
Technical field
The utility model relates to a kind of dilute phase fluidization roasting furnace, the compound furnace wall of specifically a kind of dilute phase fluidization roasting furnace.
Background technology
Al (OH) 3Dilute phase fluidization roasting furnace is a kind of based on dilute phase, the large-scale calciner of rare dense combination.The inner lining material duty of roaster is: the dehydration of formation aluminium hydroxide 10% and aluminium hydroxide are to the lattice conversion process of aluminium oxide in the extremely short time.In this process, stove master stove furnace lining needs the alkaline aqueous Al (OH) more than 10% of ability 3, under the elevated temperature heat dewatering state, corrode and wearing and tearing.In China, the first generation alumina roasting furnace of introduction has moved more than 10 years, and design and technique for applying are ripe, have obtained huge economic benefit.But these stoves also expose the common problem of some furnace linings damage in the repeatedly overhaul of carrying out, these problems mainly concentrate on watering on the material feeding working lining of steam stove group, and are and furnace wall integral body is built by laying bricks or stones, structural design and construction have direct relation except the material influence.The Al (OH) that research is used 3A series of industry difficult problems such as dilute phase fluidization roasting furnace novel furnace lining structure, optimal design have solved the mechanics Optimal Distribution of unshape refractory skeleton structure, and unlike material is distinguished, and expansion rate is identical.So, Al (OH) 3The appropriate design of the MULTILAYER COMPOSITE furnace wall structure of dilute phase fluidization roasting furnace (GSC) will improve furnace life greatly.
Summary of the invention
The purpose of this utility model is intended to solve above-mentioned in-problem deficiency, and a kind of rational in infrastructure, long service life, the compound furnace wall of dilute phase fluidization roasting furnace that cost is low are provided.
The utility model is the deficiency that addresses the above problem, and the technical scheme of being taked is:
The compound furnace wall of a kind of dilute phase fluidization roasting furnace, comprise steel casing, rigidity light fireproof insulation brick, unsetting light weight castable refractory layer, the heavy refractory casting bed of material, at least one metal anchorage is arranged in the compound furnace wall, metal anchorage connects into an integral body with rigidity light fireproof insulation brick, unsetting light weight castable refractory layer, the heavy refractory casting bed of material and steel casing, also is provided with flexible light weight insulation fibre felt between rigidity light fireproof insulation brick and steel casing.
Be provided with many metal anchorage in the compound furnace wall of the present invention, metal anchorage connects into an integral body with rigidity light fireproof insulation brick, unsetting light weight castable refractory layer, the heavy refractory casting bed of material and steel casing.
Metal anchorage front end described in the utility model is a V-arrangement, whole becomes Y shape, angle>60 between its front end two anchoring walls °.
The utility model adopts Y shape metal anchorage as skeleton, compound one or more layers the unsetting refractory casting bed of material of inside and outside wall or exterior wall constitutes the structure of compound sidewall, furnace wall, can make side wall inner layer is firm the combining of furnace lining and metal anchorage, wear-resisting furnace lining fixing, reinforcement, toughening effect have been played, make the side wall construction of compound formation more stable, it is the whole compound furnace wall of skeleton that the compound furnace wall of in the dilute phase fluidization roasting furnace inner furnace wall layering being built by laying bricks or stones changes into the metal anchorage, can make between the composite bed in conjunction with firmly, the furnace wall life-span is increased greatly.
The utility model has the advantages that:
1, rational in infrastructure, long service life, cost are low, safe and reliable.
2, be applicable to alternative, the old-fashioned import roaster of renewal.
A series of industry difficult problems such as 3, optimal design has solved the mechanics Optimal Distribution of unshape refractory skeleton structure, and unlike material is distinguished, and expansion rate is identical.
4, the design of metal anchorage makes its furnace wall integral body have flexibility more, and it is more reasonable to design, and will improve furnace life greatly.
