Description

Известен способ получени  двуокиси титана путем окислени  четыреххлористого титана в кислородсодержащей плазме. При этом кислород нагревают в высокочастотном газовом разр де. Однако этот способ сложен из-за сложной системы создани  кислородсодержащей плазмы.A known method for producing titanium dioxide by oxidation of titanium tetrachloride in an oxygen-containing plasma. In this case, the oxygen is heated in a high-frequency gas discharge. However, this method is complicated due to the complex system for creating oxygen-containing plasma.

С целью упрощени  процесса, предлагаетс  кислородсодержащий газ нагревать в стабилизированной электрической дуге.In order to simplify the process, an oxygen-containing gas is proposed to be heated in a stabilized electric arc.

В качестве плазмообразующего газа примен ют очищенный от пыли атмосферный воздух . Воздушную плазму получают в электродуговых нагревател х. Дл  улучшени  перемешивани  в зону реакции ввод т три плазменные струи так, что из струй образуетс  плазменна  воронка, в которую ввод т жидкий тонкорасныленный TiCU. Реагирующий поток со скоростью 700 м/сек проходит через закалочное сопло в охлаждаемый объем. Из охлаждаемого объема пылева  смесь направл етс  в систему улавливани  TiO2.Purified atmospheric air is used as plasma-forming gas. Air plasma is produced in electric arc heaters. To improve mixing, three plasma jets are introduced into the reaction zone so that a plasma funnel is formed from the jets into which liquid finely colored TiCU is introduced. The reaction stream with a speed of 700 m / s passes through the quenching nozzle into the cooled volume. From the cooled volume, the dust mixture is sent to the TiO2 trapping system.

Испытани  провод т при избытке кислорода 20%, температуре воздушной плазмы при входе в зону реакции 3000-3200°К; температуре в зоне реакции 2200-2300°К, времени пребывани  реагентов в зоне реакции 2-20-10 сек;The tests are carried out with an excess of oxygen of 20%, the temperature of the air plasma at the entrance to the reaction zone 3000–3200 ° K; the temperature in the reaction zone is 2200-2300 ° K, the residence time of the reactants in the reaction zone is 2-20-10 seconds;

расходе электроэнергии 2-3 квт-час/кг Ti02. Полученна  двуокись титана содержит 87- 97% рутила без ввода рутилизирующих добавок , диаметр частиц Ti02 0,1-0,4 мк; форма частиц сферическа  и овальна  (электронномикроскопический анализ).electricity consumption 2-3 kWh / kg Ti02. The obtained titanium dioxide contains 87-97% rutile without introducing rutilizing additives, the particle diameter of Ti02 0.1-0.4 microns; particle shape is spherical and oval (electron microscopic analysis).

Отход щий из системы улавливани  двуокиси титана хлор-газ содержит около 25 об. % хлора. Хлор - газ используют дл  получени  хлорпроизводных. В качестве плазмообразующего газа примен ют смесь кислорода и воздуха (70% кислорода, 30% воздуха), что дает возможность уменьшить расход энергии на производство двуокиси титана до 1,3- 1,5 КВТ-час/кг TiOs и получить концентрированный хлор - газ (содержание хлора около 70 об. %). Такой хлор - газ может быть использован дл  хлорировани  титансодержащего сырь .Chlorine gas discharged from the titanium dioxide trapping system contains about 25 vol. % chlorine. Chlorine gas is used to produce chlorine derivatives. A mixture of oxygen and air (70% oxygen, 30% air) is used as a plasma-forming gas, which makes it possible to reduce energy consumption for the production of titanium dioxide to 1.3-1.5 KWT / kg TiOs and to obtain concentrated chlorine gas (chlorine content is about 70% by volume). Such chlorine gas can be used to chlorinate titanium containing raw materials.
