Description
При доменной возгонке фосфора из природных фосфатов концентраци фтора в колошниковых газах незначительна и колеблетс в пределах 0,6-1,6 г/м газа и при электровозгонке 4-9,6 г/м. Вследствие этого утилизаци фтора из указанных газов обычно считаетс нерентабельной .In blast sublimation of phosphorus from natural phosphates, the concentration of fluorine in the flue gases is insignificant and varies between 0.6 and 1.6 g / m of gas and during electric sublimation 4 to 9.6 g / m. Consequently, the utilization of fluorine from these gases is usually considered unprofitable.
Предлагаемый способ значительно повышает концентрацию фтора в газах электро- или доменной возгонки фосфора дл создани рентабельности улавливани фтора из газов и переработки его на фторосодержашие соли. Одновременно он позвол ет снизить температуру плавлени шихты, что ведет к экономии электрической или тепловой энергии.The proposed method significantly increases the fluorine concentration in the gases of electro- or blast-furnace sublimation of phosphorus in order to create a profitability of trapping fluorine from gases and processing it into fluorine-containing salts. At the same time, it reduces the melting point of the charge, which leads to savings in electrical or thermal energy.
Способ термической возгонки фосфора заключаетс в том, что в шихту, которую загружают в доменную нли электропечь, соето ш чо из фосфата, углеродсодержащего и кремнийеодержащего материала, добавл ют плавиковый шпат. Количество и состав шпата определ ют в зависимости от величины концентрации фтора в газах, а также от состава исходной шихты. Например, при добавлении к шихте 4% плавикового шпата количество фтора в газах возрастает в 2-4 раза в зависимости от содержани фтора в исходной шихте и в плавиковом шпате, а также в зависимости от режима возгонки. При этом температура плавл ни шихты и температура возгонки фосфата снижаетс примерно на 100- 200, что обеспечивает соответствуюшее снижение расхода энергии.The method of thermal sublimation of phosphorus is that fluorspar is added to the mixture, which is loaded into the blast furnace of an electric furnace, made of phosphate, carbon-containing and silicon-containing material. The quantity and composition of spar is determined depending on the concentration of fluorine in the gases, as well as on the composition of the initial mixture. For example, when 4% fluorspar is added to the charge, the amount of fluorine in gases increases 2-4 times, depending on the fluorine content in the initial charge and in fluorspar, as well as depending on the sublimation mode. At the same time, the melting temperature of the charge and the sublimation temperature of phosphate are reduced by about 100-200, which ensures a corresponding reduction in energy consumption.
