HANGZHOU NUZHUO TECHNOLOGY GROUP CO., LTD.

Lub luag haujlwm tseem ceeb ntawm kev txhaj tshuaj nitrogen hauv cov mines yog raws li hauv qab no.

Tiv thaiv kom tsis txhob combustion ntawm Coal

Thaum lub sij hawm cov txheej txheem ntawm thee mining, tsheb thauj mus los thiab tsub zuj zuj, nws yog ib qho yooj yim mus cuag nrog oxygen nyob rau hauv cov huab cua, nyob rau hauv qeeb oxidation tshua, nrog rau qhov kub thiab txias maj mam nce, thiab nws thiaj li yuav ua rau spontaneous combustion hluav taws. Tom qab kev txhaj tshuaj nitrogen, cov pa oxygen tuaj yeem txo qis, ua rau cov tshuaj tiv thaiv oxidation tsis yooj yim mus ua, yog li txo qhov kev pheej hmoo ntawm kev sib tsoo thiab ua rau lub sijhawm muaj kev nyab xeeb ntawm cov thee. Yog li ntawd, PSA nitrogen generators yog tshwj xeeb tshaj yog haum rau cov goaf cheeb tsam, qub goaf cheeb tsam, thiab confined cheeb tsam.

Txhaum qhov kev pheej hmoo ntawm cov pa tawg 

Cov pa roj methane feem ntau muaj nyob hauv cov mines hauv av. Thaum lub concentration ntawm methane nyob rau hauv cov huab cua yog nyob nruab nrab ntawm 5% thiab 16% thiab muaj qhov hluav taws kub los yog qhov kub thiab txias point, qhov tawg yog heev yuav tshwm sim. Kev txhaj tshuaj nitrogen tuaj yeem ua haujlwm rau ob lub hom phiaj: diluting qhov concentration ntawm oxygen thiab methane nyob rau hauv cov huab cua, txo qhov kev pheej hmoo ntawm tawg, thiab ua raws li ib tug inert gas fire extinguishing nruab nrab nyob rau hauv cov kev tshwm sim ntawm hluav taws kub los mus tua hluav taws.

Khaws ib qho chaw tsis muaj cua nyob hauv thaj chaw Confined

Qee qhov chaw hauv cov mines thee yuav tsum tau muab kaw tseg (xws li cov chaw qub thiab cov chaw mined-tawm), tab sis tseem muaj qhov tsis txaus ntseeg ntawm kev tua hluav taws tsis tiav lossis cov roj tsub zuj zuj hauv cov cheeb tsam no. Los ntawm kev txhaj tshuaj nitrogen tsis tu ncua, ib puag ncig tsis zoo ntawm cov pa oxygen tsawg thiab tsis muaj qhov hluav taws kub hauv cheeb tsam no tuaj yeem tswj tau, thiab kev puas tsuaj thib ob xws li rov ua hluav taws xob lossis roj hluav taws xob tuaj yeem zam tau.

Nqi-Txuag & Ua haujlwm yooj yim

Piv nrog rau lwm txoj kev tua hluav taws (xws li kev txhaj tshuaj dej thiab txhaws), kev txhaj tshuaj nitrogen muaj qhov zoo hauv qab no:

1. Nws tsis ua rau cov qauv ntawm cov thee puas.
2. Nws tsis nce cov av noo ntawm mine.
3. Nws tuaj yeem ua haujlwm remotely, tsis tu ncua thiab tswj tau

Hauv kev xaus, kev txhaj tshuaj nitrogen rau hauv cov mines yog qhov muaj kev nyab xeeb, ib puag ncig tus phooj ywg thiab kev tiv thaiv zoo siv los tswj cov pa oxygen, tiv thaiv kev sib kis ntawm tus kheej thiab tshem tawm cov pa tawg, yog li ua kom muaj kev nyab xeeb ntawm cov miners lub neej thiab kuv cov cuab yeej.
