The invention discloses a large-scale non-sieve plate boiling chlorination furnace cover device, which is mainly composed of a conical furnace cover and a top cover. The bottom ring of the conical furnace cover is welded to the chlorination furnace shell. Flange connection is adopted between the shaped furnace cover and the top cover, a flexible graphite sealing ring is arranged between the flanges, a tamping layer is arranged in the conical furnace cover and the top cover, and a stainless steel bar is arranged in the tamping layer. The furnace cover device solves the environmental protection and safety problems caused by the leakage and blockage of the furnace cover during the production process of the large-scale fluidized chlorination furnace, as well as the blockage of the furnace cover aisle; Furnace output per unit area.
Description
technical field [0001] The invention belongs to the technical field of producing crude titanium tetrachloride, and in particular relates to a domestic large-scale boiling chlorination furnace cover device. Background technique [0002] At present, the industrial production of crude titanium tetrachloride generally adopts boiling chlorination and molten salt chlorination. Domestic boiling chlorination furnaces include ￠800, ￠1200, ￠1600, ￠2400, ￠2800, ￠3000 and other furnace types. There are ￠3000, ￠4000 and other types of boiling chlorination furnaces in foreign countries, especially in the United States and Japan, and the technical level is high. Foreign fluidized chlorination furnaces have high requirements on the composition of high-titanium slag (only rutile, TiO2 content ≥ 95%, strict particle size requirements), are not suitable for domestic high-titanium slag production of titanium tetrachloride. Domestic non-sieve-plate boiling chlorination furnace covers adopt dyn...
