Engine test bed tail gas treatment system and use method thereof

Abstract

An engine test bed tail gas treatment system comprises a first alkali liquor spray tower, a second alkali liquor spray tower, a circulating water tank, a variable-frequency diffuser, a wastewater treatment device and a closed cooling tower; a mounting hole for mounting the variable-frequency diffuser is formed in one side surface of the circulating water tank, and the variable-frequency diffuser penetrates through the mounting hole and then is horizontally and fixedly mounted in the circulating water tank; the circulating water tank is filled with alkaline circulating water; the variable-frequency diffuser is positioned above the alkaline circulating water. According to the engine test bed tail gas treatment system and a using method thereof, by arrangement of the closed circulating watertank and two sets of alkaline spray tables, engine test bed tail gas is treated, and gas discharged from gas outlets of the alkaline spraying towers meets the national pollutant emission standard.

Description

technical field [0001] The invention relates to the technical field of engine test environmental protection, in particular to an engine test bench exhaust gas treatment system and a use method thereof. Background technique [0002] Engine test is one of the necessary links for aerospace engines such as turbofan engines and solid impulse engines, and the engine test bench is a necessary condition for engine testing. For the engine test bench of turbofan engines, solid impulse engines and other aerospace engines, The main components of the exhaust gas are carbon dioxide and hydrogen sulfide and contain certain particulate matter. The particulate matter mainly includes boron trioxide and magnesium oxide. If the exhaust gas discharged from the test bench is directly discharged into the atmosphere, it will greatly pollute the atmosphere and cause The generation of acid rain and the particulate matter emitted at the same time will form pollutants such as PM10 and PM2.5 to pollute ...

[0002] Engine test is one of the necessary links for aerospace engines such as turbofan engines and solid impulse engines, and the engine test bench is a necessary condition for engine testing. For the engine test bench of turbofan engines, solid impulse engines and other aerospace engines, The main components of the exhaust gas are carbon dioxide and hydrogen sulfide and contain certain particulate matter. The particulate matter mainly includes boron trioxide and magnesium oxide. If the exhaust gas discharged from the test bench is directly discharged into the atmosphere, it will greatly pollute the atmosphere and cause The generation of acid rain and the particulate matter emitted at the same time will form pollutants such as PM10 and PM2.5 to pollute the atmosphere, which is extremely unfriendly. There is no mature and effective method
