Abstract
A method for rapidly detecting aldehyde ketone compounds in ambient air comprises the steps of conveying air containing aldehyde ketone compounds to a cooling device, condensing the air by the cooling device through heat transfer, condensing the aldehyde ketone compounds into discharged water, and continuously floating the dried air upwards and discharging the air to the air; step 2, the condensed water falls downwards under the action of gravity and falls into a condensed water collecting tank, and the aldehyde ketone compounds directly precipitate in the condensed water collecting tank due to the fact that the gravity is heavy; and 3, drying the condensate water collecting tank, and reserving the residual aldehyde ketone compound after removing water. The design of the cooling device effectively cools the ambient air temperature, reduces the evaporation rate of water, and screens the aldehyde ketone compounds according to different condensation points.
