Embodiment 1

[0043] In combination with the above-mentioned equipment, the specific operation steps of the titanium tetrachloride residual liquid environmental protection treatment process of the present invention are as follows:

[0044] 1) Connect the vacuum suction device and the discharge port (1) of the production device; the inside of the scrubber (4) contains a sodium hydroxide solution with a concentration of 5%-30% by weight; turn on the sanitary fan (7);

[0045] 2) Before the raffinate suction starts, start the rotary reactor (6), make the rotary reactor (6) rotate forward at an appropriate speed, and put in an appropriate amount of free water from the lime powder feed port (8) with a content of 5% active slaked lime powder; the active slaked lime powder is obtained by digesting quicklime at a high temperature above 100°C and does not contain agglomerates larger than 20mm.

[0046] 3) The lime powder loading in the rotary reactor (6) reaches the rated loading volume, and after f...

Embodiment 2

[0053] The same process steps and process parameters as in Example 1 were adopted, except that the free water content of the active slaked lime powder in 2) was changed to 10%.

Embodiment 3

[0055] The same process steps and process parameters as in Example 1 were adopted, except that the free water content of the active slaked lime powder in 2) was changed to 15%.

Abstract

The invention discloses an environment-friendly treatment technology for titanium tetrachloride residual material liquid. The environment-friendly treatment technology specifically comprises the following steps: S1: enabling a material collection tank with an inner negative-pressure state to be communicated with a titanium tetrachloride production device; pumping the titanium tetrachloride residual material liquid into the material collection tank in vacuum; S2: connecting the upper part of the material collection tank with a vacuum pump and arranging a washing device between the vacuum pump and the material collection tank; when the titanium tetrachloride residual material liquid enters the material collection tank, enabling gas, smoke and liquid, which are generated in a volatilization process, to enter the washing device communicated with the material collection tank under the pumping effect of the vacuum pump; after the gas, the smoke and the liquid are washed and purified by an alkaline solution in the washing device, pumping the liquid through the vacuum pump and emptying; S3: pumping the titanium tetrachloride residual material liquid collected in the material collection tank to a rotary type reactor through a self-suction pump and enabling the titanium tetrachloride residual material liquid and lime powder in the reactor to be subjected to batch-type control reaction inthe rotary type reactor. According to the technology disclosed by the invention, environment-friendly treatment of the titanium tetrachloride residual material liquid can be realized under smoke-freeand dust-free states.

Description

technical field [0001] The technology of the invention is a clean and environment-friendly method for disposing of titanium tetrachloride residues, and belongs to the technical field of chemical clean production. Background technique [0002] The production of titanium tetrachloride by the chlorination method of titanium raw materials such as high-titanium slag, rutile, and ilmenite will inevitably produce liquid or liquid-solid mixed titanium tetrachloride residual waste. Once discharged from the production device, it must be disposed of properly, otherwise it will pollute environment, corrosive equipment. [0003] The so-called titanium tetrachloride residue in the invention of this technology refers to the waste liquid containing titanium tetrachloride produced by emptying, replacing and cleaning the equipment pipeline of the titanium tetrachloride production device before maintenance, and the long-term shutdown of the device to clean the equipment container. Waste liqui...
