Description
Известно получение фосфорного ангидрида сжигаиием фосфора в атмосфере воздуха с последующим охлаждением газа. Такой фосфорный ангидрнд загр знен примес ми.It is known to obtain phosphoric anhydride by burning phosphorus in an atmosphere of air, followed by cooling the gas. Such a phosphoric anhydride is contaminated with impurities.
С целью повышени чистоты продукта провод т ступенчатое охлаждение газа при температурах от 800-900 до 300-400°С со скоростью 8-12 и от 300-400 до 80°С со скоростью 0,3-0,5 град, сек.In order to increase the purity of the product, gas is staged cooling at temperatures from 800-900 to 300-400 ° C at a speed of 8-12 and from 300-400 to 80 ° C at a speed of 0.3-0.5 degrees, sec.
На чертеже дана схема, г.о которой получают фосфорный апгндрид.In the drawing, a diagram is given, about which phosphate phosphate is obtained.
Расплавленный желтый фосфор нз храпнлиН1 ,а вакуум-насосом перекачпвают в расходные баки 1, из которых затем выдавливают гор чей водой в форсунку камеры сжигани 2. Воздух, подаваемый на распыление и сжигание фосфора, осушают при помош и силикагел или других осушаюш,их агентов.Molten yellow phosphorus is not snoren1, and a vacuum pump is pumped into supply tanks 1, from which they are then squeezed with hot water into the nozzle of combustion chamber 2. The air supplied to the spraying and burning of phosphorus is dried by means of silica gel and other dried agents.
Горизонтальна камера сжигани 2 представл ет собой полый цилиндр, имеюш,ий вод ную рубашку. Внутренн поверхность камеры защиш,еиа тонким слоем огнеупора. В камеру подают 250 кг фосфора в час и 2140/из осушенного силикагелем воздуха (коэффициент избытка воздуха а 2).The horizontal combustion chamber 2 is a hollow cylinder with a water jacket. Protect the inner surface of the chamber with a thin layer of refractory. 250 kg of phosphorus per hour and 2140 / from air, dried with silica gel (coefficient of air excess a 2) are fed into the chamber.
Осаждение фосфорного ангидрида происходит в двух последовательно расположенных осаднтел х 4 и 5. В нервом по ходу газа осадителе получаетс 515 кг товарного продукта в час, во втором 55 кг товарного продукта в час. Из системы осадителей газы удал ют с темиературой и очищенные фосфорной кислотой в скруббере 6 с насадкой нз керамических сот после брызгоуловнтел 7 выбрасывают в атмосферу.The precipitation of phosphoric anhydride occurs in two successive precipitators 4 and 5. In the nerve along the precipitator gas, 515 kg of commercial product per hour is obtained, in the second 55 kg of commercial product per hour. From the precipitant system, gases are removed with temperature and purified with phosphoric acid in a scrubber 6 with a nozzle of ceramic ceramic cells after the spray blender 7 is emitted into the atmosphere.

Предмет изобретени Subject invention
Способ полученн фосфорного ангидрида путем сжигани фосфора в атмосфере воздуха с последующим охлаждением полученного газа, отличающийс тем, что, с целью повышени чистоты нрод,укта, провод т ступенчатое охлаледение газа от 800-900 до 300- 400°С со скоростью 8-12 град/сек, затем от 300-400 до со скоростью 0,3-0,5 град/сек.The method obtained phosphoric anhydride by burning phosphorus in an atmosphere of air, followed by cooling the gas obtained, characterized in that, in order to increase the purity of the nucleus, the gas is conducted from 800-900 to 300-400 ° C at a speed of 8-12 degrees / s, then from 300-400 to with a speed of 0.3-0.5 degrees / s.
