Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of detailed description of the invention of the present utility model is explained.
As shown in Figure 1, this utility model provides a kind of disease prevention personal protection mask slip test device, including microgranule recurring structure 1, microgranule pre-processing structure 2, composite test storehouse part 3, Real-time Collection detection part 4, described microgranule recurring structure 1 is connected with described microgranule pre-processing structure 2, and described microgranule pre-processing structure 2, described Real-time Collection detection part 4 is connected with described composite test storehouse part 3 respectively.
Described microgranule recurring structure 1 includes source of the gas 5, defecator 6 and microgranule nebulizer 7, and described source of the gas 5 is connected with described defecator 6, and described defecator 6 is connected with described microgranule nebulizer 7.Source of the gas 5 mainly produces the compression air required for microgranule nebulizer 7, and the impurity in the compression air that defecator 6 produces for filtering source of the gas 5, microgranule nebulizer 7 is mainly used for generating standard compliant molecule.
Described microgranule pre-processing structure 2 includes neutralizer 8 and exsiccator 9, and described neutralizer 8 is connected with described microgranule nebulizer 7, and described exsiccator 9 is connected with described neutralizer 8.Microgranule pre-processing structure 2 gas containing microgranule being used for producing carries out pretreatment.Microgranule produced by microgranule recurring structure 1 is the gas with positive charge, thus need adopt neutralize method by institute with positive charge neutralization.The microgranule produced due to microgranule nebulizer 7 contains steam, so needing it is dried process.
Described Real-time Collection detection part 4 includes spectrophotometer 10, minipump 11 and filter 12, and described spectrophotometer 10 is connected with described minipump 11, and described minipump 11 is connected with described filter 12.Result of the test is mainly carried out instant detection by Real-time Collection detection part 4.Simultaneously take account of and recycle and can realize to greatest extent making full use of and emissions-reducing of test gas, adopt gas-circulating system.Minipump 11 is mainly used in extracting to spectrophotometer 10 test gas from master trip storehouse 13, it is achieved detect in real time.Filter 12 is for realizing discharging to air after the test gas extracted after detecting filtration.
Described composite test storehouse part 3 includes the master trip storehouse 13 and the intermediate filtered storehouse 14 that adjoin, described filter 12 is connected with described master trip storehouse 13, described filter 12 end is provided with the shower nozzle 15 in described master trip storehouse 13, and the junction in described master trip storehouse 13 and described intermediate filtered storehouse 14 is provided with air curtain 16.Composite test storehouse is mainly used for realizing simulation test personnel and wears the environment that personal protection mask carries out testing, and ensure that uniform and stable experimental condition.Gases used external environment condition may be produced certain pollution owing to testing, so composite test storehouse needs good sealing effectiveness, test gas leakage in storehouse when simultaneously as far as possible avoiding personnel to pass in and out.By adopting the isolation of inside Yu external environment condition to realize test cabin, the intermediate filtered storehouse 14 when design, reduce test gas leakage pollution environment, while at intermediate filtered storehouse 14 and master trip storehouse 13 medium design air curtain 16 and door, it is achieved the isolation between two storehouses.During test, can realizing the sealing in master trip storehouse 13 by closing test door, when experimenter needs to enter, air curtain 16 can realize the isolation between two storehouses, it is to avoid leakage.In order to better the slip of personal protection mask be tested, need to wear personal protection mask at the trial and carry out the action of some regulations, according to this requirement, it is necessary to design can meet the test cabin space of requirements above.
Operation principle: at microgranule recurring structure 1, source of the gas 5 produces satisfactory compression air, air is by filter 12 by after the moisture in compression air and other Impurity removals, and gas enters microgranule nebulizer 7, and microgranule nebulizer 7 uses compression air to produce the test microgranule that diameter is about 0.6 μm.Enter microgranule pre-processing structure 2, the test gas containing microgranule that microgranule recurring structure 1 produces passes sequentially through neutralization and dried, neutralizer 8 produces the electric charge of microgranule for neutralizing microgranule generating portion, exsiccator 9 for remove that microgranule generating portion produces containing the moisture in microgranule gas.Entering composite test storehouse part 3, test gas first passes through a shower nozzle 15, is fully spread by the test gas after shower nozzle 15 so that be uniformly distributed in master trip storehouse 13.During test, tester wears mask and enters intermediate filtered storehouse 14, opens the master trip of the entrance behind the door storehouse 13 between intermediate filtered storehouse 14 and master trip storehouse 13, and when door is opened, the air curtain 16 between two storehouses isolates two storehouses, it is prevented that test gas leakage in master trip storehouse 13.At the trial, data in master trip storehouse 13 are acquired by Real-time Collection detection part 4 in time, wherein detection in real time needs three groups of data of detection: test the gas background concentration in the one before people's protective mask, gas concentration in personal protection mask during test, the gas concentration in the master trip storehouse 13 outside personal protection mask during test.Real-time Collection detection part 4 adopts minipump 11 to connect spectrophotometer 10, spectrophotometer 10 joint test storehouse, the gas extracted in test cabin by minipump 11 is discharged to air after sequentially passing through spectrophotometer 10, minipump 11 and filter 12.
Above an example of the present utility model is described in detail, but described content has been only preferred embodiment of the present utility model, it is impossible to be considered for limiting practical range of the present utility model.All equalizations made according to this utility model application range change and improvement etc., all should still belong within patent covering scope of the present utility model.
