Mine Plua plav Tswj Tsis Siv Neeg Plua Plav Txhaum Cov Khoom Siv

Lub mine plua plav tswj tsis siv neeg lub tshuab nqus plua plav tiv thaiv cov khoom siv yog cov khoom siv thee hauv av uas paub txog kev tiv thaiv cov plua plav ntse raws li qhov tiag - lub sijhawm saib xyuas cov plua plav concentration. Nws feem ntau suav nrog cov khoom siv plua plav, tawg- pov thawj thiab muaj kev nyab xeeb nyob rau hauv qhov chaw tseem ceeb, lub pob hluav taws xob, thiab cov ntaub thaiv dej zoo. Nws yog qhov tsim nyog rau thaj chaw uas muaj kev hloov pauv loj hauv cov plua plav concentration xws li thee mining faces, tunneling faces, thiab hloov cov ntsiab lus. Cov cuab yeej no ntes cov plua plav hauv av hauv lub sijhawm tiag tiag siv cov plua plav sensor. Thaum cov concentration siab tshaj qhov chaw pib (xws li 10mg / m³), ​​chav tsev tseem ceeb cia li tswj lub pob hluav taws xob kom qhib thiab pib cov tshuaj tsuag hmoov av; thaum lub concentration poob qis dua tus nqi nyab xeeb, nws ncua sijhawm kaw ntawm cov tshuaj tsuag thiab ua tiav kev tswj hwm ntawm "plua plav tawm thaum dhau, nres thaum cov qauv". Cov cuab yeej ua raws li kev tawg- cov qauv pov thawj ntawm GB 3836.1-2010 thiab GB 3836.4-2010, nrog rau cov cim pov thawj tawg yog Ex ib I Mb, ua tau raws li qhov yuav tsum tau siv rau cov chaw siv roj av nrog methane thiab cov hmoov av tawg.

Kev tswj cov plua plav meej, ntawm -xav tau txau:Ua los ntawm tiag tiag -lub sij hawm saib xyuas cov plua plav concentration, nws zam cov dej pov tseg thiab txo cov plua plav ntau dhau los ntawm cov tshuaj "tshuaj tsuag tsuag". Piv nrog rau cov txheej txheem tshuaj tsuag, nws tuaj yeem txuag tau li 50% ntawm cov dej. Nyob rau tib lub sijhawm, nws ua kom ntseeg tau tias cov plua plav concentration yog ib txwm nyob hauv tus qauv kev nyab xeeb, txo qhov cuam tshuam ntawm plua plav rau kev noj qab haus huv ntawm cov neeg ua haujlwm hauv av.

Cov ntaub ntawv traceability, ntse tswj:Txhawb kev txuas mus rau lub thee mine nplhaib network. Chav saib xyuas hauv av tuaj yeem saib cov ntaub ntawv pov thawj cov plua plav, lub sijhawm txau, cov khoom siv ua haujlwm, thiab lwm yam hauv lub sijhawm. Nyob rau tib lub sijhawm, cov ntaub ntawv keeb kwm cia li khaws cia (lub sijhawm khaws cia ntau dua lossis sib npaug li 3 lub hlis), thiab cov ntaub ntawv tshaj tawm txhua hnub thiab txhua lub limtiam tuaj yeem tsim tawm, ua kom yooj yim rau kev tshuaj xyuas thiab kev tswj xyuas cov teebmeem ntawm cov plua plav hauv lub mine.

Ntau qhov kev rov ua dua tshiab, nyab xeeb thiab txhim khu kev qha:Nruab nrog plua plav sensor tsis ua hauj lwm tswb. Thaum lub sensor tsis ua haujlwm, lub tsev tseem ceeb tau hloov mus rau qhov teem caij txau hom kom tsis txhob muaj plua plav tawm ntawm kev tswj vim qhov tsis ua haujlwm sensor. Nyob rau tib lub sijhawm, chav tsev tseem ceeb tau nruab nrog kev tiv thaiv overvoltage thiab overcurrent tiv thaiv kom tsis txhob muaj qhov hloov pauv hluav taws xob los ntawm kev puas tsuaj rau cov khoom siv thiab ua kom lub sijhawm ntev - ua haujlwm ruaj khov.

Fine water mist plua plav txo, cov nyhuv zoo heev:Kev siv cov tshuaj tsuag dej zoo, cov dej me me (1-5 μm) thiab thaj chaw tshwj xeeb yog loj. Nws tuaj yeem sib tsoo thiab sib sau ua ke nrog cov plua plav, tshwj xeeb tshaj yog rau cov plua plav ua pa (particle loj Tsawg dua lossis sib npaug li 2.5 μm), nrog rau kev txo cov plua plav uas ntau dua 30% siab dua li cov khoom siv tshuaj tsuag.
