Abstract

The invention discloses a rectification container which comprises a main body arranged in an aerosol mixing pipe, a containing cavity is formed in the main body, the main body is further provided witha plurality of rectification holes penetrating through the side wall of the containing cavity, the multiple rectification holes are all located below a top plate of the aerosol mixing pipe, the containing cavity communicates with an aerosol air inlet pipe, the containing cavity is communicated with the aerosol mixing pipe through the rectification holes, the opening direction of the rectificationholes is arranged upwards, the included angle between the rectification holes and the vertical direction ranges from 30 degrees to 65 degrees, and thus aerosol flowing out of the rectification holescan collide with the pipe wall or the top plate. According to the scheme, the mixing uniformity of aerosol is greatly improved.

Description

technical field [0001] The invention relates to the technical field of precision instruments, in particular to a rectifying container. Background technique [0002] A dust particle counter is an instrument used to measure the number and particle size distribution of dust particles per unit volume in a clean environment. It can be widely used in the electronics industry, pharmaceutical workshops, semiconductors, optical or precision machining, plastics, spray paint, hospitals, environmental protection, inspection institutes and other production enterprises and scientific research departments, as well as provincial and municipal drug inspection institutes, blood centers, epidemic prevention stations, disease control Center, Quality Supervision Institute and other authoritative institutions. [0003] In order to ensure the accuracy and reliability of the dust particle counter, it is usually necessary to check the dust particle counter regularly. Generally, the aerosol generat...
