Kuyeza kwa Mayendedwe a Ammonia
Ammonia, yomwe ndi mankhwala oopsa komanso oopsa, ndi yofunika kwambiri m'mafakitale ambiri monga kupanga feteleza, kuziziritsa mafakitale komanso kuchepetsa ma nitrogen oxides. Chifukwa chake, kufunika kwake m'magawo osiyanasiyana kumapangitsa kuti pakhale zofunikira kwambiri pa chitetezo, magwiridwe antchito, komanso kulondola. Kuyeza molondola kuchuluka kwa ammonia m'mafakitale ogwiritsidwa ntchito sikuti ndi nkhani yaukadaulo chabe, komanso ndi nkhani yokhudza chitetezo.
Kusankha choyezera madzi choyenera cha ammonia kumapangitsa kusiyana pakugwira ntchito zosiyanasiyana za ammonia ya gasi ndi yamadzimadzi m'mapaipi amafakitale. Kenako deta yolondola ndi zotuluka zodalirika monga 4-20mA, RS485, kapena zizindikiro za pulse zitha kuyang'aniridwa ndikulembedwa kuti zisinthidwe nthawi yeniyeni. Ogwiritsa ntchito amatha kukonza njira mogwirizana ndi miyezo yachitetezo.
Kuwonjezera pa kuwongolera molondola njira zogwirira ntchito, kuyeza kayendedwe ka ammonia kumafunika m'njira zonse kuti muchepetse zoopsa zomwe zimayambitsa NHx ya poizoni, zomwe zingayambitse kuyabwa m'maso, mphuno, pakhosi pamlingo wochepa. Ndipo zimayambitsa kutupa kwakukulu ndi kutentha kwambiri ngati munthu akhudzidwa kwambiri. Kukhudzidwa ndi ammonia wambiri kungayambitse khungu, kulephera kupuma komanso ngakhale imfa.
Ammonia ya Gasi vs. Ammonia ya Madzi
Ammonia ya gasi ndi yamadzimadzi imasiyana malinga ndi makhalidwe ake komanso momwe amagwiritsidwira ntchito m'mafakitale. Kusiyana kwakukulu pakati pa mitundu iwiri ya ammonia kumakhudza kwambiri njira zogwirira ntchito, kusungira, ndi kuyeza. Ammonia ya gasi imapangidwa ndi maatomu a nayitrogeni ndi maatomu a haidrojeni, omwe amawola kutentha kwambiri kuti apange nayitrogeni ndi haidrojeni. Kuphatikiza apo, ammonia ya gasi imasanduka nitric oxide mothandizidwa ndi chothandizira pakakhala zinthu zoyenera.
Ammonia woipa wa mpweya umawononga ndipo umakumana ndi chinyezi kwambiri ukakumana ndi madzi ndi nembanemba ya mucous. Ammonium hydroxide yopangidwa ndi mpweya ndi yoopsa kwambiri ku minofu.
Ammonia yamadzimadzi imachokera ku kusungunuka kwa mpweya wa ammonia m'madzi, komwe kumadziwika kuti ndi madzi a ammonia, omwe ndi mtundu wa madzi osasinthasintha opanda mtundu omwe ali ndi fungo loipa. Kutenthedwa komwe kungachitike kuyenera kusamalidwa mosamala pamene ammonia ikugwirizana ndi madzi. Ammonia yamadzimadzi imaphwa ikakumana ndi mpweya, ndikubwerera ku mawonekedwe a gasi. Chinthu chinanso ndichakuti imatha kusungunuka mosavuta kukhala zinthu zachilengedwe monga alcohols ndi ethers.
Zofunikira pa Kuyeza ndi Kulamulira Kuyenda kwa Madzi
Popeza mpweya wa ammonia uli ndi mphamvu zowononga komanso zina zomwe zimapangitsa kuti mpweya ukhale wosalala, kusinthasintha koyenera ndikofunikira posankha mita yolondola ya madzi popanda kusokoneza kulondola kwake. Kupereka bwino kwa ammonia kumafuna mita yoyendera madzi molondola kwambiri. Ndipo mphamvu yolimbana ndi dzimbiri ya mita yoyendera madzi ndi yofunika kwambiri kuti ipirire nyengo zovuta.
Zinthu monga kutentha, kuthamanga kwa mpweya, ndi kukhuthala kwa mpweya ziyenera kuganiziridwa kuti zitsimikizire kuti pali miyeso yokhazikika komanso yolondola. Kuchepetsa kutentha kumathandiza kuti zinthu ziwerengedwe molondola chifukwa cha kusintha kwa kutentha.
Mavuto a Kuyeza Mpweya wa Ammonia
Mwachidule, pali zovuta zosiyanasiyana pakuyeza mpweya ndi madzi a ammonia.
✤Kusinthasintha kwakukulu ndi kuchitapo kanthu
✤Katundu wowononga komanso woopsa
✤Sungunuka mu zinthu zachilengedwe zosungunulira
✤Kuchepetsa kutentha ndi kupanikizika
Kodi Ammonia Imagwiritsidwa Ntchito Bwanji Popanga?
Kugwiritsa ntchito kwambiri ammonia ku USA ndi gwero lamphamvu la nayitrogeni kuti zomera zikule. Ammonia yoposa 80% imagwiritsidwa ntchito popanga feteleza wolimba m'munda waulimi. Feteleza wolimbawo ukhoza kugwiritsidwa ntchito mwachindunji m'nthaka kapena kusinthidwa kukhala mchere wosiyanasiyana wa ammonium. Monga tonse tikudziwa, kuwonjezera nayitrogeni kumakhudza kumera kwa tirigu wambiri.
Gwiritsani ntchito bwino mankhwala apadera a ammonia m'makina oziziritsira mafakitale. Kutentha kwakukulu kumatha kuyamwa kuchokera ku ammonia ya mpweya panthawi yosungunuka, zomwe zimapangitsa kuti kutentha kukhale kochepa pamalo ochepa. Chifukwa chake, izi zimasiya ammonia kukhala imodzi mwa mafiriji ogwira ntchito bwino kwambiri.
Mwachitsanzo, mafakitale opangira chakudya amafuna mafiriji a mafakitale kuti azilamulira kutentha. Katundu wowonongeka amakhalabe watsopano komanso wabwino mogwirizana ndi miyezo yokhwima yokhudza ukhondo ndi chitetezo cha chakudya. Ndiwokondedwa kwambiri kuposa mafiriji ena chifukwa cha kuzizira kwake kochuluka. Kuphatikiza apo, zotsatira zake zochepa pa chilengedwe zimatsatira zomwe zikuchitika masiku ano pakuchepetsa mpweya woipa wa carbon ndi ndalama zamagetsi.
Ammonia ndi njira yosinthira zinthu pochepetsa mpweya wochokera ku ma nitrogen oxides. Kawirikawiri, imayamba kugwiritsidwa ntchito ndi ma nitrogen oxides poyesa kuwasintha kukhala nayitrogeni yoteteza chilengedwe ndi madzi mu njira yochepetsera choletsa (SCR) komanso njira yochepetsera choletsa (SNCR). Ma nitrogen oxides, omwe ndi omwe amachititsa kuti mpweya uipitse komanso mvula ya asidi, amatha kusinthidwa kukhala zinthu zopanda vuto pambuyo pa SCR ndi SNCR.
Zolondolakuyeza kayendedwe ka amoniyaikukula kwambiri mu mafakitale odzipangira okha ndi kukonza zinthu kuti isunge malamulo oyendetsera ntchito komanso kuchepetsa mphamvu ya NOx, momwe kupotoka pang'ono kungakhudze magwiridwe antchito a makina ndi zotsatira za chilengedwe.
Chiyeso Choyendera Madzi a Ammonia Chovomerezeka
Pezani choyenerachoyezera kuchuluka kwa mpweyandiLonnmeter. Mitundu yosiyanasiyana ya ntchito zapamwamba zogwiritsira ntchito kuchuluka kwa madzi ndi mpweya wogwirizana. Choyezera kuchuluka kwa madzi chimapereka kuwerenga kodalirika komanso kolondola ndipo chimakuthandizani kuchotsa kuyeza mobwerezabwereza kwa madzi ndi manja. Siyani ogwiritsa ntchito kutali ndi malo oopsa kapena oopsa, tsimikizirani chitetezo chanu momwe mungathere.
