Description
Как Известно, при электрической или доменной возгоике фосфора -из шихты (фосфаты + кЬКС) носле конденсации фосфора в колошниковом газе остаетс фосфор в количестве, соответствующем его парциальной упругости, и фоСфОристый воДОрод. Эти компоненты обесценивают колошниковый газ, дела невозможным его применение ни дл топливных целей ни дл целей синтеза.As is known, in the case of electric or blast furnace phosphorus of the charge (phosphates + kx), phosphorus condenses in the flue gas, phosphorus remains in an amount corresponding to its partial elasticity, and a phosphorus is formed. These components depreciate the flue gas, making it impossible to use either for fuel purposes or for synthesis purposes.
Согласно насто щему изобретению, предлагаетс осво|болоденный от элементарного фосфора колошниковый газ дополнительно промывать раствором фосфорной кислоты, содержащей озон.According to the present invention, it is proposed that the flue gas exhausted from elemental phosphorus is additionally washed with a solution of phosphoric acid containing ozone.
На чертеже приведена оДна из возможных схем осуществлени предлагаемого cnocoida.The drawing shows ONE of the possible implementation schemes of the proposed cnocoida.
Пойле коиденсацни фосфорз и от делени пыли в конденсаторе 2, колощБиковый газ направл етс в скруббер 3. Двига сь в нем по принципу противотока и встреча на с1воем пути раствор фосфорной кислоты в воде, насыщенной oeoHiOM, пары фосфора и фосфористого водорода реагируют с последним.Coil condensation of phosphorus and from separation of dust in condenser 2, collar Peak gas is directed to scrubber 3. Moving it on the counter-flow principle and meeting on a pathway a solution of phosphoric acid in water saturated with oeoHiOM, a pair of phosphorus and phosphorous hydrogen react with the latter.
Схематически реакцию их взаимодействи можно выразить следующим образом:Schematically, the reaction of their interaction can be expressed as follows:
Р, + 100, - 2P.,O,-f 10Q РН„ -1- 40, - Н,Рб, + 4Q.Р, + 100, - 2P., O, -f 10Q РН „-1-40, - Н, Рб, + 4Q.
Образовавшиес продукты окислени фосфора и фосфористого водорода абсорбируютс фосфорной кислотой, распределенной а большой поверхности насадки скруббера 3.The resulting oxidation products of phosphorus and hydrogen phosphide are absorbed by phosphoric acid, distributed over the large surface of the scrubber packing 3.
Отдавша озон фосфорна кислота из скруббера 3 стекает в бак 4, откуда она направл етс насосом 7 в насытитель-скруббер 5. Распредел сь на большой поверхности кварцевой насадки и встреча по мере опускани вниз кислород, насыщенный озоном, фосфорна кислота в скруббере вновь обогащаетс последним и стекает в бак 1, откуда она насосом 8 вновь подаетс в скруббер 3 дл окислени Р и РН,,.The ozone phosphoric acid from the scrubber 3 flows into the tank 4, from where it is sent by the pump 7 to the saturation scrubber 5. Distributed over a large surface of the quartz nozzle and meeting as it descends down the oxygen saturated with ozone, the phosphoric acid in the scrubber again enriches it last and flows into tank 1, from where it is pumped again by pump 8 to scrubber 3 for oxidation of P and PH.
Рециркул ци pac-fBOpai фосфорной кислоты повтор етс до предела нужного насыщени его фосфорной кислотой , образующейс вследствие окислени Р и РНз озоном.The recycling of pac-fBOpai phosphoric acid is repeated to the extent necessary to saturate it with phosphoric acid resulting from the oxidation of P and PH 3 with ozone.
Кислород, отдав свой озоН, вновь направл етс по трубе 9 в озонатор 10, конструкци которого должна отвечать наибольшей экономичности.Oxygen, after giving up its ozone, is re-directed through pipe 9 to the ozonizer 10, the design of which should correspond to the greatest economy.
Можно дл получени озона примен ть воздух, однако применение кислорода снижает расход электроэнергии почти В три раза.It is possible to use air to obtain ozone, but the use of oxygen reduces the power consumption by almost three times.
Возмещение расхода- кислорода, пошедшего на обраэоваиие овона, осуш;есавл етс впуском в оэонаггор 10 по мере надобности, иовой порции кислорода по трубе 9.Compensation of the consumption of oxygen, which went to the formation of the ovon, is dried; it is let in by entering into the gas pump 10 as necessary, and a portion of the oxygen through the pipe 9.
Очищенный от Р и РН. колошниковый газ может иттн дл всех видов синтеза н топливных целей.Purified from P and PH. top gas can be used for all types of synthesis and fuel purposes.
Предмет и 3 о б р е т е н и Subject and 3 oreteni
Спосо:б очистки газов, а1олучающ1ихс при возговке фосфора, от фосфористого водорода, отличающийс тем, ЧТО газы, освобожденные от элементарного фосфора известными приемами , промывают раствором фосфорной кислоты, содержащей озон.The method is used to purify gases, which are obtained when phosphorus is recovered, from hydrogen phosphorous, in that the gases liberated from elemental phosphorus by known methods are washed with a solution of phosphoric acid containing ozone.
