. Йаобретение относитс к области автоматического управлени производством хлори- доз металлов.. The invention relates to the field of automatic control of the production of metal chlorides.

Известен способ автоматического управлени шахтным хлоратором, заключающийCS в регулирова1-гаи соотношени расходов входного и выходного продуктов изменением расхода входного продукта с коррекцией по уровню ШИХТЫ в хлораторе. Управление По таавестному способу приводит к неполному использованию хлора, так как он не позвол ет учесть вли ние изменени температуры расплава хлоратора на степень использовани хлора,There is a known method of automatic control of a shaft chlorinator, which includes the CSS in the regulation of the ratio of the input and output product costs by changing the input product flow rate with correction according to the level of DIRECTION in the chlorinator. Management By the way of the procedure leads to the incomplete use of chlorine, since it does not allow to take into account the influence of the change in the temperature of the chlorine melt on the degree of utilization of chlorine,

Известен способ автоматического упраалени хлоратором, заключающийс в том, что поцачу исходных материалов корректируют по величине электрического сопротивлени расплава в хлораторе.A known method of automatic control of the chlorinator is that the aim of the starting materials is corrected by the value of the electrical resistance of the melt in the chlorinator.

Недостатком этого способа вл етс то, что, ввиду большой инерхшонности процесса, даже после коррекции подачи исходных ма териалов существует длительный проскок хлора,The disadvantage of this method is that, due to the large intershonosity of the process, even after correcting the supply of initial materials, there is a long chlorine leakage,

Кроме того, он не позвол ет поддерживать заданную текшературу расплава хлоратора , при этом сложность устройств, необходимых дл реализации способа, затрудн ет его осуществление.In addition, it does not allow to maintain the specified melting pattern of the chlorinator melt, and the complexity of the devices necessary for implementing the method makes its implementation difficult.

Наиболее близким из известных способов по технической сущности вл бтс способ автоматического управлени хлоратором путем поддержани весовых расходов хлора в хпоргазе кислорода в кпоргазе и концентрате с последующим регулированием сосуоаошени хлор-концентрат (с коррекцией по содержанию двуокиси титана в расплаве ) и соотношени кислород-кокс (с коррекцией по содержанию углерода в расплаве)The closest of the known methods according to the technical essence is the method of automatic control of the chlorinator by maintaining the weight of chlorine in the oxygen xpgas in the gas and concentrate, followed by controlling the chlorine concentrate (adjusted for the content of titanium dioxide in the melt) and the oxygen-coke ratio (with correction of the carbon content in the melt)

Однако такой способ не обеспечивает поддержание посто нной температуры расплава , а при хлорировании, например, редкоземельного сырь даже незначительные изменени температуры вызывают резкое изменение физических свойств ргюплава, что приводит к проскоку хлора.However, this method does not maintain the constant temperature of the melt, and during the chlorination of, for example, rare-earth raw materials, even minor temperature changes cause a drastic change in the physical properties of the ore melt, which leads to chlorine leakage.

Claims

The purpose of the invention is to increase the degree of use of chlorine. This is achieved by those. that in the known method of automagical control of the chlorinator by maintaining the chlorine and oxygen gas consumption of weight in chlorine and concentrate, followed by adjusting the chlorine-concentrate ratio and oxygen-coke ratio, the given melt temperature is additionally maintained by changing the electric power melt depending on, from a change in the chlorine weight flow rate. With the correction of the electrical power applied to the size of the melt drained from the chlorinator. The method is explained in the drawing. The signal from the calculator of the chlorine weight flow, proportional to the heat of exothermic reactions, through. j The stabilizing unit 1 is fed to the summing unit 2, to which a signal simultaneously proportional to the heat of electric heating is fed through the converter 3 and the scaling unit 4. The signal from the summing unit 2 enters the input of the regulator 5, which changes the input through the rods to melt the electrical power so that the temperature of the melt remains constant. A correction signal from the weight sensor 6 of the melt melted from the chlorinator is also fed to the input of the controller 5. When reducing, for example, the amount of chlorine by 20 kg, the regulator 5 increases the electrical power of the transformer to 31.35 kW, and to maintain r;: -, the set melt temperature during slcZE from the chlorinator 2.85 kg of the melt regulator 5 increases the electrical power by 0.9 KW, and with an increase in the amount of chlorine, the regulator reduces the electrical power of the transformer. The use of an inventer, for example, in the chlorination of rare earths, allows an increase in the degree of chlorine utilization by 3%. Claims The method of automatically controlling the chlorinator by maintaining chlorine and chlorine gas weight consumption, chlorine gas and oxygen concentrate, followed by adjusting the chlorine-concentrate ratio and oxygen-coke ratio, characterized in that, in order to increase chlorine utilization, the melt temperature is changed by changing electric power supplied to the melt depending on the change in the chlorine weight flow with the correction of the electric power supplied according to the value of fused of the chlorinator from the melt.
