An oxychlorination gas dryer

Abstract

This utility model discloses an oxychlorination gas dryer, which consists of a gas drying tank and a gas inlet cooling assembly. The gas drying tank has a tank body, with an inlet pipe fixed to the lower end and an outlet pipe fixed to the upper end. Multiple inverted U-shaped tubes are fixed in a circular array at the top of the inlet pipe. A certain volume of concentrated sulfuric acid solution is placed inside the tank, with the tops of the inverted U-shaped tubes submerged in it. A backflow check valve is installed at the bottom of the inlet pipe to prevent gas backflow. The gas inlet cooling assembly includes a cooling tank, with multiple TEC semiconductor cooling chips adhered in a circular array on its outer surface. A cooling fan is fixedly connected to the heating end of the cooling tank. During operation, the oxychlorination gas is first cooled by the cooling assembly before entering the drying tank. It is then dispersed into the concentrated sulfuric acid solution through the inlet pipe and the inverted U-shaped tubes to remove moisture. The dried gas is discharged from the outlet pipe. This dryer can effectively reduce the moisture content of oxychlorination gas and improve the drying effect.
