Kev paub ntawm cov kev daws tshwj xeeb urea

Tsheb urea thiab feem ntau hais txog urea muaj qhov sib txawv. Lub tsheb urea yog kom txo cov nitrogen thiab hydrogen sib xyaw ua pa phem emged los ntawm diesel cav, thiab ua lub luag haujlwm hauv kev tiv thaiv ib puag ncig. Nws muaj cov kev xav tau nruj me ntsis, uas yog qhov tseem ua rau muaj kev nyab xeeb urea thiab deionized dej. Ib qho ntawm cov cim zoo tseem ceeb yog kev tswj qib ntawm impurities. Cov hais, hlau ions, zaub mov thiab lwm yam impurities hauv urea muaj ntau heev, thiab cov kev phom sij yog pom tseeb heev. Ib zaug tsis muaj kev cuam tshuam ntxiv, nws yuav ua rau tom qab ua tsis tiav, thiab tsim cov nyom ua rau kom muaj kev phom sij rau tom qab ua haujlwm. Thiab rau kaum ntawm txhiab tus neeg ntawm Yuan tom qab ua tiav, lossis xaiv cov khoom urea pom zoo los ntawm cov khw.

Cov yam ntxwv yog dab tsi?

Weichai tshwj xeeb urea hais daws tau raws li International Standard Iso2224-1, German Tus Qauv DIN70070 thiab cov neeg ua pov thawj zoo.

Cov kev tsim txom ntawm cov khoom lag luam cuav thiab cov tshuaj tsis zoo ntawm cov txiaj ntsig area tsis txaus, tsis muaj peev xwm tshem tawm, cov lus qhia yooj yim tuaj yeem tshem tawm, rhuab thiab hau kom yaj. Txawm li cas los xij, kev siv lub tsheb ntev ntev uas tsis tau raws li cov qauv tshuaj ntsuam xyuas tau zoo, txo kom tsis txhob muaj kev puas tsuaj thiab lub neej muaj kev puas tsuaj rau kev hloov pauv, ua rau muaj kev puas tsuaj rau kev ua haujlwm tsis ua haujlwm.

Super Huv

Txhawm rau kom ua tiav cov ultra-siab uraa ua kom muaj kev ua tau zoo, Weichai tshwj xeeb urea kev daws teeb meem nyob rau hauv cov txheej txheem ntau lawm, thiab cov khoom ntim yuav tsum muaj hmoov av dawb. Kev ua haujlwm ua haujlwm theem pib ntawm SCR SCRABLE: Lub tso pa nkag mus rau hauv cov pa yeeb yaj kiab los ntawm lub compger Turbine. Nyob rau tib lub sijhawm, los ntawm cov kev txhaj tshuaj urea txhaj tshuaj Hauv cov txheej txheem txo qis, cov conferration ntawm urea daws yog ib qho tseem ceeb tsis tuaj yeem txhim kho cov kev hloov kho ntawm ammas thiab kev tsim ntawm cov pa paug almonia.

Hloov dua siab tshiab

Nrog cov kev daws tshwj xeeb tshwj xeeb nrog kev xav ntawm 32.5% raws li txo tus neeg sawv cev; Raws li cov qauv kev teeb tsa ntawm kev kho mob tom qab kev kho, urea kev suav nyiaj rau kwv yees li 5% ntawm kev siv roj. Siv lub peev xwm ntawm 23LDe urea urea tank ua piv txwv, cov nqi mais yuav ncav cuag 1500-1800 kilometers.

Urea ntxiv dej: feem ntau ib tug neeg nug seb are urea tuaj yeem ntxiv cov dej ntxhia pob zeb, cov dej npau npau thiab lwm yam tshuaj. Qhov no yog kiag li tsis tau, muaj ntau cov impurities nyob rau hauv cov kais dej, deb dhau ntawm peb qhov kev soj ntsuam qhov muag liab qab. Calcium, magnesium, sodium thiab lwm yam hauv cov kais dej thiab cov ntxhia dej yog yooj yim los tsim cov kua tshuaj, yog li thaiv cov khoom siv tau yooj yim, ua rau kev ua txhaum cai. Cov kua ntxiv hauv urea, tsuas tuaj yeem yog cov dej deionized. Cov urea tank ua rau qib yuav tsum tau muab khaws cia ntawm 30% thiab 80% ntawm tag nrho cov ntim ntawm epea tank. Urea cia: Kev daws teeb meem urea yuav tsum khaws cia rau hauv lub thawv kaw hauv qhov chaw txias, qhuav, deb ntawm cov muaj zog oxidants. Thaum sau, xws li ncaj qha rau hauv UREA Tank pov tseg urea splashing, thiab tsim cov pa phem ib puag ncig, thiab ua kom muaj kuab paug ib puag ncig. Cov khoom siv kev ua haujlwm tau pom zoo.

Lus rau txhaws UAS: uree daws yog corrosive rau daim tawv. Yog tias daim tawv nqaij lossis qhov muag tau ntxiv, yaug nrog dej sai li sai tau; Yog tias tus mob txuas ntxiv, thov nrhiav kev pab kho mob. Yog tias nqos tsis saib xyuas, txwv tsis pub ntuav, nrhiav kev kho mob sai sai
