Embodiment

[0063] The cyclone dust collector is used to separate the gas and solid from the material obtained by the sieveless fluidized chlorination furnace through the upper slag discharge method, and the TiCl 4 The gas enters the condensation process, FeCl 3 , MnCl 2 Equiboiling point than TiCl 4 The high gas is condensed in the cyclone dust collector and transported to the closed intermediate slag bin. At the same time, part of the fine particles of titanium-rich materials and petroleum coke particles brought out by the gas also fall into the 20m 3 The closed intermediate slag bin is mixed with metal chloride to obtain mixed dry slag, namely chlorinated waste residue (the specific composition is shown in Table 1) (the output of mixed dry slag is 4t / h), and then the mixed dry slag passes through the bottom of the closed intermediate slag bin The rotary feed valve enters the closed conveyor (feeding speed is 4t / h), and then the chlorinated dry slag is transported to the closed mixing...

Abstract

The invention discloses a method for treating fluidizing chlorination residues. The chlorination residues contain at least one of ferric chloride, manganese chloride, magnesium chloride, nickel chloride and chrome chloride. The method comprises the following steps of (1) discharging the chlorination residues to a closed intermediate residue bin through a pipe; (2) discharging the chlorination residues to at least one closed conveyer via a first chlorination residue outlet; and (3) discharging the chlorination residues to at least one closed stirring tank via a second chlorination residue outlet, and supplying lime cream for the closed stirring tanks so that chloride in the chlorination residues and the lime cream react to generate precipitations to obtain cream mixture. By the method, the problems that a large amount of waste water is generated in a process of treating the fluidizing chlorination residues, and a technological process of treatment is long are solved.

Description

technical field [0001] The invention belongs to the technical field of metallurgy and chemical industry, in particular, the invention relates to a method for treating boiling chlorination waste residue. Background technique [0002] Boiling chlorination technology is the mainstream chlorination technology for producing chlorination titanium dioxide and sponge titanium. The main reaction process is to add titanium-rich materials, petroleum coke, and sodium chloride into the chlorination furnace according to the ratio, and chlorine gas is introduced from the bottom of the furnace. At a certain temperature, the above materials react chemically, and the main product is TiCl 4 , the obtained product is separated from gas and solid by cyclone dust collector, TiCl 4 The gas enters the subsequent condensation and refining system, and the FeCl 3 , MnCl 2 Such metal chlorides and a small amount of fine-grained titanium-rich materials and petroleum coke all enter the slag phase and ...
