Description

TECHNICAL FIELD

[0001] The utility model relates to the field of special vehicle cabin air purification, specifically relates to a composite purification device suitable for special vehicle cabin flue gas. BACKGROUND

[0002] In the process of special vehicle gun shooting, harmful gas accumulation often occurs in the cabin, the main components of which include smoke, CO, NO2, NH3, etc. Although forced ventilation can reduce the concentration of harmful gas to a certain extent, the phenomenon of harmful gas exceeding the standard still often occurs, resulting in poisoning symptoms such as headache, nausea, palpitation, weakness, dullness and significant reduction of action accuracy of the passengers, which directly affects the combat capability of the passengers. In severe cases, the concentration of harmful components may be too high to cause personnel shock, endangering the safety of personnel.

[0005] In the field of civilian cars, the purification of harmful components in automobile exhaust is all carried out by using ternary catalytic technology, which uses ternary catalyst to realize the harmless treatment of CO and NOx. However, the catalyst needs to use the high temperature (above 400℃) of automobile exhaust to complete the purification of gas. This kind of technical method is not suitable for the purification of harmful gas in the cabin of special vehicle, on the one hand, it will consume the limited power resources of the vehicle, and on the other hand, it will affect the thermal comfort of personnel.
