Abstract
Изобретение относитс к способам очистки газов от вредных примесей окислов серы и азота, используемых Б химической и нефтехимической промышленности , теплоэнергетике и автотранспорте , и позвол ет повысить степень очистки. Повышают влажность газа, загр зненного и SOj , до величины не менее 90%, затем его подают в разр дный блок, где создают барьерный разр д при частоте разр дного тока 6,5 - 15 кГц и напр жении на электродах 9 - 12 кВ, после чего направл ют в конденсатор, где получают водный раствор серной и азотной кислот. При расходе газа 1 - 25 , температуре 0-650 С, исходной концентрации N0 и 5( равной 0,001 - 1,5 и 0,025 - 1,2% об. соответственно получают степень очистки от N0 и (Л равную 99,2 - 99,9 и 98,5 - 99,97, (Соответственно. 2 табл.The invention relates to methods for purifying gases from harmful impurities of sulfur and nitrogen oxides used by the chemical and petrochemical industries, heat and power engineering, and motor vehicles, and allows an increase in the degree of purification. The humidity of the gas contaminated with SOj is increased to at least 90%, then it is fed to the discharge unit, where a barrier discharge is created at a discharge current frequency of 6.5–15 kHz and a voltage across the electrodes of 9–12 kV, after which they are sent to a condenser, where an aqueous solution of sulfuric and nitric acids is obtained. With a gas flow rate of 1 - 25, a temperature of 0-650 C, an initial concentration of N0 and 5 (equal to 0.001 - 1.5 and 0.025 - 1.2% by volume, respectively, a degree of purification is obtained from N0 and (L equal to 99.2 - 99, 9 and 98.5 - 99.97, (Respectively. 2 tab.

Цель изобретения - повышение степёни очистки от окислов азота и серы.The purpose of the invention is to increase the degree of purification from oxides of nitrogen and sulfur.
Пр им ер. Загрязненный газ, содержащий 1,5% Νθχ и 0,75% S02 , при Ю 0°С и объемным расходом 1000 нм3/ч подают в увлажнитель, где его увлажняют до влажности 90%. После этого газ направляют в разрядный блок, где создают барьерный разряд. Частота <5 разрядного тока 10 кГц, напряжение на электродах 9 кВ. Затем газ пропускают через стандартный конденсатор, где происходит выделение образовавшихся кислот из газового потока. 20Pr im er. A contaminated gas containing 1.5% Νθ χ and 0.75% S0 2 is supplied to a humidifier at 10 ° C and a volumetric flow rate of 1000 nm 3 / h, where it is moistened to a moisture content of 90%. After that, the gas is sent to the discharge block, where a barrier discharge is created. Frequency <5 discharge current 10 kHz, voltage at the electrodes 9 kV. Then the gas is passed through a standard condenser, where the formation of formed acids from the gas stream takes place. 20
Концентрацию загрязняющих примесей на выходе контролируют.путем химического анализа отбираемых проб. После очистки газ содержит 0,001% ЛЮ и 0,0005% 502, т.е. степень очистки составляет 99,9%.The concentration of contaminants at the outlet is controlled by chemical analysis of the samples taken. After purification, the gas contains 0.001% LJ and 0.0005% 50 2 , i.e. the degree of purification is 99.9%.
Влияние напряжения и частоты на степень очистки отражено в табл.1.The effect of voltage and frequency on the degree of purification is shown in Table 1.
При оптимальных частотах и напряжениях степень очистки газа от ^0г и S02 практически не Изменяется при изменении расхода газа, его температуры и исходной концентрации загрязняющих компонент, что отражено в табл.2.At optimal frequencies and voltages, the degree of gas purification from ^ 0 g and S0 2 practically does not change with a change in the gas flow rate, its temperature and the initial concentration of polluting components, which is reflected in Table 2.
