Iodine sampler

Abstract

This invention relates to the field of sampling equipment technology and includes a housing. The housing contains a sampling device, an air inlet connection assembly, a fan, and a cooling fan. The sampling device includes a horizontally positioned sampling chamber, the outer end of which is fixedly connected to the housing. An iodine sampling box is installed inside the sampling chamber. The air inlet connection assembly includes a horizontally positioned connecting pipe that communicates with the sampling chamber. A differential pressure sensor and a ring-shaped flow-limiting plate are installed between the connecting pipe and the sampling chamber. The fan includes an inlet pipe and an outlet pipe. The inlet pipe communicates with the connecting pipe, and the outlet pipe is installed within the housing. The cooling fan is mounted on the housing, with its outlet facing the fan. A heat dissipation vent is provided on the bottom plate of the housing. This invention enables the sampling of iodine in gases, improves the accuracy of flow measurement, reduces space occupation, facilitates movement, and provides active heat dissipation to ensure normal sampling.
