Abstract
Использование: машиностроение, а именно способ нейтрализации отработавших газов двигател внутреннего сгорани . Сущность изобретени : способ нейтрализации осуществл ют путем предварительного охлаждени в теплообменнике впускаемого в него потока газа, подачи потока в первый жидкостной нейтрализатор, последующего подогрева потока в теплообменнике, его подачи во второй каталитический нейтрализатор и выпуска, в атмосферу, причем в качестве источника подогрева используют тепло впускаемого потока. 1 ил.Usage: mechanical engineering, namely, a method of neutralizing exhaust gases of an internal combustion engine. SUMMARY OF THE INVENTION: The neutralization method is carried out by pre-cooling the gas stream inlet into the heat exchanger, supplying the stream to the first liquid catalyst, then heating the stream in the heat exchanger, supplying it to the second catalyst and releasing it into the atmosphere, using heat as a source of heating intake flow. 1 ill.
Description
Изобретение относитс к машиностроению , а именно к нейтрализации отработавших газов двигател внутреннего сгорани .The invention relates to mechanical engineering, in particular to the neutralization of exhaust gases of an internal combustion engine.
Цель изобретени - повышение эффективности ..The purpose of the invention is to increase efficiency ..
На чертеже представлен пример реализации предлагаемого способа.The drawing shows an example implementation of the proposed method.
Отработавшие газы через первый K.QW- тур теплообменника 1 направл ют на жидкостный нейтрализатор 2. Затем через второй контур теплообменника 1 на каталитический нейтрализатор 3, после которого очищенные газы выпускают в атмосферу.The exhaust gases through the first K.QW round of the heat exchanger 1 are sent to the liquid catalyst 2. Then, through the second circuit of the heat exchanger 1, to the catalytic converter 3, after which the purified gases are released into the atmosphere.
Предлагаемый способ был реализован в модели и проведены испытани . Они показали , что при работе с марганцевым катализатором его активность сохран лась в течение 100-120 ч, при этом эффективность всего устройства достигала по саже, бенз(а}- пирену, окислом азота (в пересчете на NOa), окиси углерода и углеводородам - 90-95%.The proposed method was implemented in the model and tested. They showed that when working with a manganese catalyst, its activity was maintained for 100-120 h, while the efficiency of the entire device reached soot, benz (a} - pyrene, nitric oxide (in terms of NOa), carbon monoxide and hydrocarbons - 90-95%.
При работе с медно-хромовыми катализатором его активность сохран лась практически неизменной в течение 300 ч. Эффективность 90-95%, Таким образом, предлагаемый способ позвол ет значительно повысить эффективность системы очистки отработавших газов.When working with a copper-chromium catalyst, its activity remained practically unchanged for 300 hours. Efficiency 90-95%. Thus, the proposed method can significantly increase the efficiency of the exhaust gas purification system.
Формул а изо бретени Способ нейтрализации потока отработавших газов путем предварительного охлаждени в теплообменнике впускаемого в него потока, подачи потока в первый нейтрализатор , последующего подогрева потока, его подачи во второй каталитический нейтрализатор и выпуска в атмосферу, отличающийс тем. что, с целью повышени эффективности, подогрев осуществл ют в теплообменнике, в качестве источника подогрева используют тепло впускаемого потока, а в качестве первого нейтрализатора - жидкостной.Formulas of the invention A method of neutralizing an exhaust gas stream by pre-cooling the inlet stream into the heat exchanger, supplying the stream to the first catalyst, then heating the stream, feeding it to the second catalyst and discharging into the atmosphere, characterized in that that, in order to increase efficiency, heating is carried out in a heat exchanger, heat of the intake stream is used as a heating source, and liquid as the first neutralizer.
