(54) СПОСОБ ОГНЕВОГО ОБЕЗВРЕЖИВАНИЯ СТОЧНЫХ ВОД(54) METHOD FOR FIREWATERING OF WASTEWATER
1one
Изобретение относитс к области обезвреживани сточных вод химической промышленности .This invention relates to the field of wastewater disposal in the chemical industry.
Известный способ огневого обезвреживани сточных вод, содержащих органические и легкоплавкие дтинеральные соли, заключаетс в том, что сточные воды ввод т тангенциально в циклонную топку, распыл ют, выжигают органические примеси, а минеральные соли в виде расплава вывод т из топочного пространства .A known method of fire disposal of wastewater containing organic and low-melting dinineral salts is that wastewater is introduced tangentially into a cyclone furnace, sprayed, organic matter is burned out, and mineral salts are removed from the furnace space in the form of a melt.
Недостатками известного способа вл ютс невозможность обезвреживани сточных вод, содержащих органические и тугоплавкие минеральные примеси, например фосфат натри ; кроме того, необходимы дополнительные сооружени дл улавливани золы, например циклоны, рукавные фильтры, а осуществление процесса обезвреживани сточных вод при температурах пор дка 1500-1600°С сопр жено с быстрым износом сооружений.The disadvantages of this method are the impossibility of disposal of wastewater containing organic and refractory mineral impurities, such as sodium phosphate; In addition, additional facilities for trapping ash, such as cyclones, bag filters, are needed, and the process of disposal of wastewater at temperatures of the order of 1500-1600 ° C is associated with rapid deterioration of facilities.
Предлагаемый способ отличаетс от известного тем, что сточные воды, содержащие тугоплавкие минеральные соли, ввод т в пленку расплава легкоплавких солей.The proposed method differs from the known one in that wastewater containing refractory mineral salts is introduced into the melt film of low-melting salts.
Это позвол ет уменьшить объем очистных сооружений и вести нроцесс обезвоживани при 000°С.This makes it possible to reduce the volume of sewage treatment plants and maintain the dewatering process at 000 ° C.
Предлагаемый способ осуществл ют следующим образом:The proposed method is carried out as follows:
Пример. В вертикальной циклонной нечт сжигают природный газ. В горелочные устройства подают воздух, необходимый дл горени топлива и горючих нримесей сточных вод.Example. In the vertical cyclone nets burn natural gas. Air is supplied to the burners, which is necessary for burning fuel and combustible wastewater.
В продукты сгорани топлива, имеющие температуру 1500°С, ввод т распыленную сточную воду производства гербицидов. Состав сточной воды следующий:Spray waste water from herbicide production is introduced into the combustion products at a temperature of 1500 ° C. The composition of the waste water is as follows:
Хлористый натрий230 г/лSodium chloride 230 g / l
Формальдегид1 г/лFormaldehyde 1 g / l
Метиловый спирт10 г/лMethyl alcohol 10 g / l
Анилин13 г/лAnilin13 g / l
Полианины7 г/лPolyanine7 g / l
Капли сточной воды испар ют, горючие примеси разлагают и окисл ют, а частицы легкоплавкой соли (температура плавлени 810°С) плав т, сепарируют на стенках печи с образованием пленки расплава, стекающей вниз к пережиму.Drops of waste water evaporate, combustible impurities decompose and oxidize, and particles of low-melting salt (melting point 810 ° C) are melted, separated on the furnace walls with the formation of a melt film flowing down to pinch.
