Abstract

The invention relates to a solid particle chemical protection garment inward leakage rate testing system control cabinet. The control cabinet comprises a cabinet body; an aerosol generating device, a dilution device, an aerosol detecting device, and a vacuum pump, which are disposed on the cabinet body. The gas inlet of the aerosol generating device is communicated with an air compressor, and the gas outlet of the aerosol generating device is communicated with the dilution device, and saline aerosol is generated. The gas inlet of the dilution device is communicated with the air compressor and the aerosol generating device, and the gas outlet of the dilution device is communicated with a testing cabin, and the saline aerosol is diluted. The gas inlet of the aerosol detecting device is communicated with the testing cabin and a tested protection garment, and the gas outlet of the aerosol detecting device is communicated with the vacuum pump, and gas concentration in the testing cabin and the tested protection garment is detected. The vacuum pump is used to suck the to-be-tested gas in the testing cabin and the tested protection garment into the aerosol detecting device for detection. The control cabinet is used to control the solid particle chemical protection garment inward leakage rate test conveniently and effectively, and is used to detect whether the protection garment meets a national technical standard.

Description

technical field [0001] The invention relates to the technical field of detecting the inward leakage rate of chemical protective clothing for solid particles, in particular to a control cabinet for a testing system for the inward leakage rate of chemical protective clothing for solid particles. Background technique [0002] In an environment with particulate chemical pollution, workers must wear protective clothing that protects the human body. [0003] According to GB / T 29511-2013 "Protective Clothing Solid Particulate Chemical Protective Clothing", it is required to test the inward leakage rate of protective clothing to judge whether the protective clothing meets the technical requirements for use. [0004] At present, there are no finalized products for testing the inward leakage rate of solid particle chemical protective clothing at home and abroad, and many difficulties will be encountered when testing the inward leakage rate of protective clothing. [0005] The definit...
