As you can see in this picture, during experiments conducted in a perchloric acid fume hood, there may be an aerosol release process of perchloric acid, so the fume hood needs to be exhausted under rated large air volume exhaust conditions. The design value is 1300CMH. Perchloric acid and ventilation The alkaline water behind the cabinet deflector is mixed and contacted, and the chemical reaction is: HClO4+NaOH====NaClO4+H2O
The neutralized product is a neutral product with a pH value between 7 and 14, so the circulation treatment system designed this time is made of chemically resistant materials. A buffer tank is set up at the lower part of the fume hood, and the outlet side is connected to a PP water pump. The water pump is connected to the atomization pipe behind the deflector. The water pump outputs the alkali solution to the atomization pipe in the form of medium pressure, and passes through the atomization pipe into fine water droplets. The product is mixed and contacted with the perchloric acid gas to complete the chemical reaction. Affected by gravity, the product re-enters the buffer tank of the water pump through the technical interlayer for circulation.
