[0009] Preferably, the outlet of the gas distribution pipe is located at the bottom of the liquid in the reaction shell, so that the atmosphere can fully react with the neutralizing solvent in the reaction shell.
[0010] Preferably, the collection unit includes an air pipe, an air pump, a placement table, a storage box, a drain pipe, a measuring box, an observation window, and a scale.

[0011] Preferably, the collection units have two groups of combinations, so that different gases can be collected.
[0012] Preferably, a brightly colored float is installed inside the measuring box, so that the height of the float can be directly observed through the observation window, thereby facilitating reading the volume of the collected gas.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The stratified sampling device for air pollution prevention and control is installed with a reaction unit, so that the inside of the reaction shell is heated to a neutralizing solution, so that the gas in the atmosphere enters the inside of the reaction shell, and the rest of the atmosphere contains a mixture of several gases, so that the gas reacts with the neutralizing solvent to generate precipitation, so that the gas to be extracted cannot react with the neutralizing solvent, thereby facilitating the collection of the gas, and at the same time, by starting the transmission member, the transmission member drives the rotating shaft to rotate, thereby controlling the stirring blade to stir the neutralizing solvent inside the reaction shell, so that the neutralizing solvent and air react more fully.
