Description

The invention relates to mechanical engineering, in particular to devices for cleaning exhaust gases of an internal combustion engine.

The aim of the invention is to improve the reliability of cleaning exhaust gases by creating an optimal temperature in a liquid purifier.

The drawing shows a diagram of the proposed device.

The device contains an internal combustion engine 1 with a liquid-cooled system 2, a heat exchanger 3 and a gas purifier 4 with an inlet 5 and an outlet 6 with nozzles on the casing 7. The casing 7 is partially filled with a cleaned fluid with 8 liquid. 42% are used as cleaning fluid. sodium hydroxide solution. The inlet 5 communicates with the heat exchanger 3, and the gas distributor 9 is placed in the housing, communicating with the help of the pipeline 10 with the inlet

During the bubbling of gases through a layer of caustic soda, the reaction of NaOH + CO HCOONa occurs at 200-150 ° C, in addition, conditions are created for absorption by the aqueous solution of caustic soda nitrogen dioxide

2NO2 + 2NaOH NaNO3 + NaNO2 + H2O and carbon dioxide

2NaOH + CO2 Na2CO3 + H2O, and soot and other impurities are better absorbed.
