Abstract

The invention relates to a device for denitration ammonia escape testing of diesel engine tail gas. The device comprises a tail gas guide pipe. A mixing area, a temperature control area and a test area are sequentially arranged in the tail gas guide pipe. The mixing area is used for evenly mixing tail gas led in; the temperature control area control temperature of the evenly mixed gas; and the test area is used for performing denitration ammonia escape testing on the gas undergoing temperature control. The device for denitration ammonia escape testing of diesel engine tail gas can meet miniaturization and expansibility requirements of narrow pipes.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a diesel engine tail gas denitrification ammonia escape test device. Background technique [0002] With the continuous progress of life and the continuous development of science and technology, people's travel requirements are getting higher and higher. Due to its high power and heavy load, diesel engines widely provide power for people's travel tools and large equipment, such as diesel trucks, diesel buses, diesel agricultural machinery, diesel generators, diesel ships, etc., and become an important driving force for modern economic development. . Diesel engines have penetrated into all aspects of people's working life and social economy. But at the same time, the pollution caused by diesel combustion is also increasing. In this context, cleaner and more environmentally friendly design and exhaust gas treatment have become the future development dir...
