Integrated blowing instrument and radioactive feed liquid detection system

An integrated blowing instrument disclosed by the present invention comprises a box body, a differential pressure transmitter assembly, a blowing assembly and an airflow communication assembly, a plurality of installation positions are arranged in the box body, and the differential pressure transmitter assembly, the blowing assembly and the airflow communication assembly are detachably installed in the installation positions respectively. The installation position of the air flow communication assembly is adjacent to the installation positions of other assemblies, a pipeline is arranged in the air flow communication assembly, vent holes are formed in the surface of the air flow communication assembly, the differential pressure transmitter assembly and the air blowing assembly are detachably connected with the vent holes, and therefore air flow circulation is achieved through the pipeline in the air flow communication assembly. The integrated blowing instrument does not introduce human errors, has good univers
