РАСКРЫТИЕ ИЗОБРЕТЕНИЯSUMMARY OF THE INVENTION
Задачей изобретения является разработка усовершенствованной системы для очистки газов от газообразных и механических примесей. Технический результат - повышение эффективности очистки и расширение арсенала средств аналогичного назначения - достигается тем, что система очистки газов, содержащая газопровод, конический корпус, подводящий трубопровод и электрод с иглами, подключенный к источнику тока, в верхней части корпуса расположена коаксиально емкость с водой, а в нижней части - коллектор отвода воды, емкость установлена с возможностью образования рабочей зоны между жидкостным осадительным электродом из заземленного потока воды, стекающего по внутренней поверхности корпуса и иглами электрода, согласно изобретению, снабжена кольцевым соплом для подачи газа в рабочую зону, при этом сопло образовано верхним и нижним коническими элементами, а радиус кривизны острия игл не превышает 50 мк. Расстояние между иглами соответствует длине игл.The objective of the invention is to develop an improved system for cleaning gases from gaseous and mechanical impurities. The technical result - improving the efficiency of cleaning and expanding the arsenal of means for similar purposes - is achieved by the fact that the gas cleaning system containing a gas pipeline a casing, a supply pipe and an electrode with needles connected to a current source, in the upper part of the casing there is a coaxial container with water, and in the lower part there is a collector for water drainage, the container is installed with the possibility of forming a working zone between the liquid precipitation electrode from an earthed stream of water flowing down on the inner surface of the housing and the electrode needles, according to the invention, is equipped with an annular nozzle for supplying gas to the working area, while the nozzle is formed by upper and lower conical elements, and the radius rivia of the tip of the needles does not exceed 50 microns. The distance between the needles corresponds to the length of the needles.
Система снабжена устройством регулирования положения электрода с иглами.The system is equipped with a device for regulating the position of the electrode with needles.
Система снабжена устройством регулирования положения корпуса и имеет флотационную установку для очистки воды, соединенную с коллектором отвода воды, и конвейер для транспортировки шлама.The system is equipped with a device for regulating the position of the housing and has a flotation unit for water treatment connected to a collector for water drainage and a conveyor for transporting sludge.

Установка кольцевого сопла, образованного коническими элементами, позволяет направлять газ в рабочую зону так, что вектор скорости газа на срезе сопла параллелен образующей конуса корпуса. Это повышает эффективность массообмена и улучшает процесс очистки. Радиус кривизны острия иглы ограничен значением 50 микрон, так как при большем радиусе интенсивность очистки падает. Радиус кривизны острия иглы должен быть как можно меньше, например, порядка 5 микрон. В этом случае достигается наибольшая эффективность очистки.The installation of an annular nozzle formed by conical elements allows directing gas into the working area so that the gas velocity vector at the nozzle exit is parallel to the generatrix of the cone of the housing. This increases the mass transfer efficiency and improves the cleaning process. The radius of curvature of the tip of the needle is limited to 50 microns, since with a larger radius, the cleaning intensity decreases. The radius of curvature of the needle tip should be as small as possible, for example, of the order of 5 microns. In this case, the highest cleaning efficiency is achieved.

Очищенные газы отводят через воздуховод 18.Gas, for example, polluted atmospheric air or flue gas is pumped through the fans 12 into the gas pipeline 1. Gas consumption regulate with gates 11. In the equalization gas chamber 13, the gas enters through the inlet 15, and then goes into the annular nozzle 21 formed by the upper 22 and lower 23 conical elements, for subsequent supply to the working area of the installation between the liquid precipitation electrode from an earthed flowing water flowing down along the inner surface of the housing 2 and the needles of the electrode 4. The gas is supplied from the nozzle 21 so that the gas velocity vector at the nozzle exit is parallel to the generatrix of the cone of the housing 2. The electrode 4 is fed yazhenie 30 kV, current of 1.5 microamperes. The water in the tank 5 is grounded. Water, forming a liquid precipitation electrode, serves as an acceptor of impurities extracted from gas. When moving the flow of water and gases in the working zone, a high mass transfer rate is ensured, in which particles of harmful impurities are charged from the electrode 4 and settle on the surface of the water flowing down the conical surface of the housing 2. The contaminated water with impurities deposited in it through the collector b is sent to a flotation unit 9 for water purification, the extracted sludge is transported by conveyor 10 to a hopper - sludge collector 24, and water is sent back to the purification system by pump 25 to form a liquid precipitation electrode. The purified gases are discharged through the duct 18.
Восстановление химических компонентов примесей производится атомарным водородом, выделяющимся при пропускании газов в смеси с воздухом между электродом с иглами и жидкостным электродом. Например, при очистке газов ТЭЦ или газов металлургического производства процесс очистки от соединений серы происходит по следующей схеме:The chemical components of impurities are reduced by atomic hydrogen released when passing gases in a mixture with air between an electrode with needles and a liquid electrode. For example, when cleaning gases from a thermal power plant or gases from metallurgical production, the process of cleaning sulfur compounds occurs according to the following scheme:
H2O = OH^ H+ H+ + е" = HH 2 O = OH ^ H + H + + e " = H
4OH" - 4e" = O2 + 2H2O 6H + SO2 = H2S + 2H2O4OH " - 4e " = O 2 + 2H 2 O 6H + SO 2 = H 2 S + 2H 2 O
SO2 + 2H2S = 3Sj + 2H2O Загрязняющие компоненты, например сера или углерод, выделяются в элементарном виде и собираются во флотационной установке 9 в виде механических примесей и шлама.SO 2 + 2H 2 S = 3Sj + 2H 2 O Contaminating components, such as sulfur or carbon, are released in elementary form and collected in flotation unit 9 in the form of mechanical impurities and sludge.
ПРОМЫШЛЕННАЯ ПРМЕНИМОСТЬINDUSTRIAL APPLICABILITY
Система очистки может быть использована в металлургической промышленности при очистке газов от оксидов серы, железа и других токсичных газообразных и дисперсных примесей. При очистке газов теплоэлектростанций от оксидов углерода возможно осуществить работу станций в замкнутом цикле, который заключается в следующем: сжигание исходного углеродного топлива; очистка отходящих газов от оксидов углерода с получением элементарного углерода; повторное сжигание полученного в результате очистки углерода для получения электроэнергии. Этот процесс можно осуществлять непрерывно, что позволяет значительно снизить расход невозобновляемых природных источников углеродного топлива.The purification system can be used in the metallurgical industry for the purification of gases from oxides of sulfur, iron and other toxic gaseous and dispersed impurities. When cleaning the gases of thermal power plants from carbon oxides, it is possible to carry out the work of the stations in a closed cycle, which consists in the following: burning of the initial carbon fuel; purification of exhaust gases from carbon oxides to obtain elemental carbon; re-burning the resulting carbon purification to generate electricity. This process can be carried out continuously, which can significantly reduce the consumption of non-renewable natural sources of carbon fuel.
Кроме того, полученный в результате очистки углерод может быть использован в производстве каучуков, резин и других различных эластомеров, так как состоит из ультрамелкодисперсной однородной фракции, содержащей до 10 мае. % фуллеренов и позволяет получить износостойкие шины для транспортных средств. In addition, the carbon obtained as a result of purification can be used in the manufacture of rubbers, rubbers, and other various elastomers, since it consists of an ultrafine homogeneous fraction containing until May 10. % fullerenes and allows you to get wear-resistant tires for vehicles.
