Abstract

The invention relates to a bracket for air sampling at a fan inlet, belongs to the technical field of air quality inspection sample collection, and solves the problem of air sampling of a main airflowof the fan inlet. A cross connector is a cross-shaped frame, the four ends of the cross connector are respectively inserted into four sampling bracket bodies, the four sampling bracket bodies are hollow main body structures, and the cross connector is connected with the sampling bracket bodies as an integrated piece; the sampling bracket main bodies are located at the front air inlet of a fan airinlet duct; a sampling bracket fixing clamp is located at the outer edge of the fan air inlet duct, one end of the sampling bracket fixing clamp is welded with the sampling bracket main bodies, and the other end of the sampling bracket fixing clamp connects four sampling brackets in series with a fan fixing steel strip by bolts to embrace and tightly fasten to the outside of the fan air inlet duct; a plurality of sampling heads are evenly mounted on the sampling bracket main bodies; and sampling head connecting hoses are connected with the lower ends of the sampling heads. The bracket is applicable to the collection of air samples at air intake ports at different locations.

Description

technical field [0001] The invention relates to an air sampling bracket used for fan inlets, and belongs to the technical field of sample collection for air quality inspection. Background technique [0002] In the marine environment, sea surface salt mist aerosol is the main killer of ships at sea, and sea surface salt mist aerosol is an important factor in the service life of equipment and power units in the cabin. Understanding the concentration and humidity of sea surface salt mist aerosols is a prerequisite for the design of anti-corrosion measures. How to measure the salt mist, humidity and dust in the air is a problem to be solved. Since the air composition parameters are different in different spatial positions in the atmosphere, the content of salt mist, humidity and dust in the air sucked by the fan is How many? To be obtained through sampling analysis. Due to the large diameter of the fan on the ship, how to collect air samples in the main airflow of the fan bec...
