Method for reducing tail gas suspended particles of diesel engine in sound field environment

Abstract

The invention discloses a method for reducing tail gas suspended particles of a diesel engine in a sound field environment. High-temperature tail gas exhausted from a combustion chamber of the diesel engine mainly comprises suspended particles and easily liquefied gas components; the high-temperature tail gas becomes non-condensed moderate-temperature tail gas after being cooled by a radiator; the moderate-temperature tail gas is introduced into a strong sound standing wave sound wave guide pipe coupled with a cooling system and subjected to a cooling process gradually reinforced in a smoke flowing direction; the cooling temperature is slightly lower than the dew point temperature of gas components in the tail gas flowing through a cooling position; the gas components are liquefied to suspended liquid particles with smaller particle diameters; all the suspended particles are contacted with one another under the effects of sound force, inertia force, Brownian motion force and gravity; and the suspended particles grow to unbreakable dry large particles with the suspended liquid particles as adhesive, so that the removal of the suspended particles in the exhausted tail gas by fully using the easy-liquefied gas components in the tail gas is realized.

Description

technical field [0001] The invention relates to a method for removing suspended particles in flue gas with sound waves, in particular to a method for removing suspended particles in diesel engine exhaust, specifically a method for reducing suspended particles in diesel engine exhaust in a sound field environment. Background technique [0002] Diesel engine is an important energy conversion system for obtaining mechanical energy power source. With the increase in the number of motor vehicles, the demand for mechanical power increases, and the impact of the direct emission of suspended particulate matter in the exhaust gas after burning diesel oil on air pollution cannot be ignored. At present, diesel engine vehicles are not equipped with a unified standard device for effectively removing suspended particulate matter in exhaust gas after diesel combustion. The high-temperature flue gas produced by diesel engine combustion contains a large number of easily liquefied gas compon...

Problems solved by technology

In the current technological innovation, it does not involve the process of controlling the cooling of the flue gas by adjusting the cooling process, and the suspended liquid particles generated by the liquefaction of the easily liquefied gas components uniformly dispersed in the exhaust gas are used as the binder to fully bind the dispersed gas in the flue gas. Suspended particles, aggregated into large dry solid particles that are easy to settle, so as to achieve the purpose of fully utilizing the easily liquefiable gas components produced in the combustion exhaust gas to remove suspended particulate matter in the exhaust exhaust gas
