Abstract

The utility model discloses a lining structure of a chlorination furnace in a titanium tetrachloride production process. The internal layer structure of the lining structure of the chlorination furnace in the titanium tetrachloride production process is a phosphate fireproofing brick layer, a phosphate castable layer is arranged on the outer side of the phosphate fireproofing brick layer, a clay brick layer is arranged on the outer side of the phosphate castable layer, and a light-weight insulating brick layer is arranged on the outer side of the clay brick layer. The erosion intensity of the lining structure is enhanced by adopting the mode, the service life of the chlorination furnace is prolonged from 6-7months to 16-17 months, and can even reach more than 20 months, the operation rate of the chlorination furnace is improved, the maintenance cycle is shortened, and maintenance cost is lowered.

Description

The inner lining structure of chlorination furnace in titanic chloride production process
Technical field
The utility model relates to a kind of titanium sponge production equipment, relates in particular to a kind of chlorination furnace lining structure being applied in titanic chloride production process.
Background technology
As everyone knows, titanium tetrachloride is to produce the primary raw material of titanium sponge, and titanium tetrachloride to be the compound that adopts chlorine and high titanium slag and petroleum coke react generation acquisition at certain temperature in chlorination furnace.Chlorination furnace conversion zone temperature general control is 800 ℃~1000 ℃ left and right, and furnace pressure is minute-pressure, and inner lining of furnace is subject to material and chlorine violent scour, and furnace inner environment is that acidity is very easily corroded.
At present, the inner lining structure that uses chlorination furnace base cone section in existing titanic chloride production process is phosphate pouring material layer, generally adopts phosphate pouring material poured up at a time in the time building stove; At the inner lining structure on chlorination furnace base cone section top from inner phosphate pouring material layer, clay brick heat-insulation layer, light-weight insulating brick layer and the alumina silicate heat-insulation layer of being outwards followed successively by.In the inner lining structure of above-mentioned chlorination furnace, because the intensity of phosphate pouring material layer is low, so its resistance to erosion intensity is low, and chlorination furnace is produced titanium tetrachloride to fluidizing chlorination method, it is very big that this section is born scouring intensity, especially chlorination furnace base cone section, therefore the service life of the chlorination furnace of this inner lining structure is shorter, generally within about 6~7 months, need blowing out to maintenance in use, but the shutdown maintenance cycle is longer, affects the operating rate of stove.
Utility model content
The purpose of this utility model is just to provide the inner lining structure of chlorination furnace in a kind of titanic chloride production process, to solve in background technology.
For achieving the above object, the utility model is by the following technical solutions:
Endothecium structure of the present utility model is phosphate fire brick layer, at the arranged outside phosphate pouring material layer of phosphate fire brick layer, at the arranged outside clay brick layer of phosphate pouring material layer, at the arranged outside light-weight insulating brick layer of clay brick layer.
The thickness of described phosphate fire brick layer is 230mm, and the thickness of phosphate pouring material layer is 284mm, and the thickness of chamotte brick layer is 230mm, and the thickness of light-weight insulating brick layer is 60mm.
In the utility model, the whole inner lining structure of chlorination furnace is from inner phosphate fire brick layer, phosphate pouring material layer, the light-weight insulating brick layer of being outwards followed successively by, adopt the scouring intensity that has strengthened in this way inner lining structure, extended to 16~17 month from original 6~7 months the service life of chlorination furnace, even may reach more than 20 month, improve the operating rate of stove, existing chlorination furnace base cone section is that phosphate pouring material layer is in the time needing repairing, need to be by cast again after full phosphate pouring material layer fragmentation, but phosphate pouring material layer is not easy fragmentation, generally need 16~18 Ren Fen class Threes to work continuously, could it is all broken about 15 days, the inner lining structure on chlorination furnace base cone section and its top is all set to three layers, and internal layer is phosphate fire brick layer, when maintenance, only the phosphate refractory brick of phosphate fire brick layer need be removed, generally 6~7 people can complete about 3 days, shorten maintenance cycle, reduce maintenance cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, endothecium structure of the present utility model is phosphate fire brick layer 1, at the arranged outside phosphate pouring material layer 2 of phosphate fire brick layer, at the arranged outside clay brick layer 3 of phosphate pouring material layer, at the arranged outside light-weight insulating brick layer 4 of clay brick layer.
As improvement of the present utility model: the thickness of described phosphate fire brick layer 1 is 230mm, the thickness of phosphate pouring material layer 2 is 284mm, the thickness of chamotte brick layer 3 is 230mm, the thickness of light-weight insulating brick layer 4 is 60mm, can directly replace original inner lining structure with this inner lining structure, without buying the chlorination furnace matching with inner lining structure, can save input cost.
