Silica Gel Sand Kayan Aikin Jiyya

Silica gel yashi magani kayan aikin
Yashin silica gel (wanda kuma aka sani da yashi silicate ko yashi sodium silicate) wani yashi ne na inorganic wanda aka saba amfani dashi a masana'antar simintin gyaran kafa. Babban makasudin kayan aikin jiyya na silica gel yashi shine don sake haɓakawa da sake sarrafa tsohon yashi yadda ya kamata tare da rage farashi da rage ƙaƙƙarfan fitar da sharar gida, ƙarƙashin yanayin kiyaye aikin yashi.
Babban kayan aikin gyaran yashi na silica gel yashi shine "tsarin sabunta yashi", saboda tsarin taurara da rarrabuwa na yashi na silica gel ya sa saman tsohon yashi ya rufe shi da fim ɗin gel ɗin silicon mai wuya, wanda sake amfani da shi kai tsaye zai yi tasiri sosai ga aikin yashi.
Cikakken tsarin kula da yashi na silica gel yakan haɗa da manyan abubuwan da ke gaba:
1. Babban kayan aikin sabuntawa (wanda aka rarraba ta ka'idar sabuntawa)
Wannan shine "zuciya" na tsarin, yana ƙayyade ingancin yashi da aka sabunta da kuma farashin tsarin.
Busassun kayan aikin sabuntawa
Ƙa'ida: Cire fim ɗin inert a saman tsohon yashi barbashi ta hanyar babban karo - babban karo, gogayya, da niƙa.
Babban kayan aiki:
Na'ura mai saurin haɓaka tasirin Centrifugal: Ana jefa kwararar yashi ƙarƙashin aikin babban rotor mai sauri da yin karo da goge tare da farantin da aka yi niyya ko yashi. Wannan a halin yanzu shine kayan aikin sabunta bushewa mafi amfani da inganci.
Injin sabunta tasirin tasirin iska: Yi amfani da iskar iska mai ƙarfi{0} don fitar da ɓangarorin yashi don yin karo da juna a cikin ɗakin sabuntawa ko tasirin lalacewa{1}} faranti mai juriya.
Na'urar farfadowa da jijjiga: Ta hanyar girgiza, barbashin yashi suna haifar da juzu'i tsakanin juna, tare da ingantacciyar ikon ragewa, galibi ana amfani da su azaman farfadowa na farko ko haɗe tare da wasu kayan aiki.
Siffofin: Sauƙaƙan kayan aiki, ƙarancin amfani da makamashi, babu samar da ruwan sha. Koyaya, sauran abubuwan Na₂O a cikin yashi da aka sabunta suna da ɗan girma (yawanci har yanzu yana cikin kewayon 0.3-1.0%), dacewa da simintin ƙarfe da simintin ƙarfe tare da ƙarancin ingancin yashi, ko azaman riga-kafi na sabunta jika.
Kayan aikin sabunta rigar
Ƙa'ida: Yi amfani da wanke ruwa, gogewa, da motsa jiki da juzu'i don narke da cire fim ɗin gel ɗin silicon da alkali karfe oxides a saman ɓangarorin yashi.
Babban kayan aiki:
Guguwar na'ura mai aiki da karfin ruwa: Babban kayan aiki. Yashi -ana tura ruwan yashi tare da tangent ɗin zuwa cikin na'urar, yana haifar da matsananciyar juzu'i, dogaro da ƙarfin centrifugal da juzu'i tsakanin ɓangarorin don tsaftacewa.
Na'ura mai gogewa/ tanki mai shara: Tanki mai ƙarfi mai ƙarfi don shafan yashi na inji{0}} cakuda ruwa.
Tsari mai gudana: Tsohuwar yashi → Farfaɗowar ruwa (shafawa, cycloning) → Dewatering (allon jijjiga, dehydrator) → bushewa (na'urar bushewar gado, uku- bushewar ganga).
Siffofin: Ingantattun yashi da aka sabunta shine mafi girma, ragowar Na₂O na iya ragewa zuwa ƙasa da 0.1%, yana gabatowa matakin sabon yashi, tare da ƙimar sake amfani da shi (har zuwa 90%). Duk da haka, tsarin yana da wuyar gaske, zuba jari yana da yawa, akwai batun kula da ruwa (yana buƙatar tsarin kula da ruwa), da kuma amfani da makamashi yana da yawa. Ana amfani da shi musamman don ƙaƙƙarfan sassa na simintin ƙarfe na simintin gyare-gyare masu inganci, ƙayyadaddun simintin gyare-gyare, ko layukan samarwa tare da tsananin yashi.
Farfaɗowar thermal da haɓaka haɓakawa
Thermal farfadowa: A high yanayin zafi (sama da 700 digiri), da silicon gel film a saman saman yashi barbashi da aka ƙone da kuma 酥化, sa'an nan kuma cire ta hanyar inji gogayya. Ana buƙatar tanderun konewa, tare da babban amfani da makamashi, gabaɗaya ana amfani da shi don buƙatu na musamman ko haɗe da busassun hanyoyi.
Haɗewar sabuntawa: Haɗa hanyoyi biyu ko fiye don cimma sakamako mafi kyau da fa'idodin tattalin arziki. Mafi yawanci shine "hanyar bushewa + hanyar rigar" ko "Hanya mai zafi + Hanyar bushewa". Alal misali, da farko cire mafi yawan fim din inert ta hanyar bushewa, sa'an nan kuma mai zurfi mai tsabta ta hanyar rigar, wanda zai iya rage nauyin kaya da sarrafa farashin tsarin hanyar rigar.
2. Tallafawa kayan aikin magani
Cikakken layin jiyya yashi na silica gel shima ya haɗa da hanyoyin haɗin gwiwa:
Kayayyakin magani kafin{0}:
Kayan aiki na murƙushewa: Ana amfani da shi don sarrafa tsohon yashi wanda ya dunƙule bayan jefar da wani yanki, kamar masu girgiza, muƙamuƙi, da sauransu.
Kayan aiki na Magnetic Separation: Yana kawar da ƙazantar maganadisu kamar waken ƙarfe da gefuna masu tashi daga yashi, yana kare kayan aiki na gaba.
Sieving kayan aiki (kamar firgita fuska): Yana kawar da manyan tubalan yashi, ainihin ƙasusuwa, da sauransu, daga ƙazantattun abubuwan maganadisu.
Post{0}} tsarin kula da yashi:
Kayan aikin sanyaya yashi: Zazzabi na yashi da aka sabunta na iya zama babba, kuma yana buƙatar sanyaya don kusa da zafin jiki kafin amfani. Na'urorin sanyaya gado da aka saba amfani da su ko na'urar sanyaya faifai sau biyu{1}. Ma'ajiyar yashi da tsarin isar da saƙo: Ya haɗa da kwandon ajiyar yashi, lif ɗin guga, na'urar jigilar bel, na'urorin jigilar huhu, da sauransu, waɗanda ake amfani da su don kewayawa da adana kayan yashi.
Na'ura mai haɗawa: Yana haɗa yashi da aka sake yin fa'ida (ko gauraye da sabon yashi) tare da sabon gilashin ruwa, magunguna, da sauransu, don shirya yashi mai gyare-gyare mai amfani. Yawanci yana amfani da manyan injina masu haɗawa- ingantacciyar rotor{3}}.
Kayan aikin taimako na muhalli (musamman don tsarin rigar):
Tsarin kula da ruwa: Yana kula da ruwan sharar da aka samu ta hanyar sake sarrafa jika ta hanyar matakai kamar flocculation, sedimentation, da tacewa, samun nasarar sake yin amfani da ruwa da bushewa na sludge (wanda ya ƙunshi silica mai kyau da alkali).
Tsarin tarin kura: Yana saita huluna masu tarin kura da jaka{0}}nau'in masu tara ƙura a cikin kura{1}} wuraren da ke fitar da ƙura kamar murkushewa, nunawa, isarwa, da bushewa don tara ƙura.
III. Zaɓin kayan aiki da shawarwarin kwararar aiki
Zaɓin sake sarrafa kayan aiki da kwararar tsari ya dogara ne akan:
Kayan simintin simintin gyare-gyare da buƙatun inganci: Ƙarfe na simintin simintin gyare-gyare da ingantaccen sassa na simintin ƙarfe yawanci suna buƙatar yashi mai sarrafa jika; sassa na simintin ƙarfe na gabaɗaya na iya amfani da yashi mai bushewa mai inganci-.
Girman sikelin samarwa da sikelin: Babban{0}}asashen ci gaba da samarwa ya dace da cikakken layukan sake sarrafa rigar mai sarrafa kansa; ƙananan batches, iri-iri iri-iri na iya ɗaukar busassun reprocessing ko sassa masu sarrafa rigar.
Bukatun muhalli da kasafin kuɗi: Rigar sake sarrafa saka hannun jari da farashin aiki suna da yawa, amma akwai yuwuwar fitar da ƙaƙƙarfan sharar gida (yashin sharar gida); Kudin sarrafa busassun ba su da yawa, amma duk da haka wasu yashi sharar gida yana buƙatar zubar da shi daga ƙarshe.
Misali na kwararan tsari:
Dry reprocessing line na ruwa gilashin yashi magani kayan aikin:
Cire kura → Crushing → Magnetic Separation → Screening → Dry reprocessing Machine → Yashi sanyaya → Adana → Hadawa.
Wet reprocessing line na ruwa gilashin yashi magani kayan aiki:
Cire kura → Murkushewa → Rabewar Magnetic → Na'urar sake sarrafa rigar (shafewa + murzawa) → Dewatering → bushewa → Sanyaya → Adana → Hadawa.
(Tsarin gyaran ruwa na gaba: Ruwan sharar gida → tanki mai lalata → Tacewar matsa lamba → Sake amfani da ruwa mai tsafta, ana kwashe sludge.) Takaitawa.
Makullin kayan aikin gyaran yashi na sodium silicate ya ta'allaka ne cikin inganci kuma maras tsada{0}}satun yashi. Yanayin masana'antu na yanzu shine:
Neman sabuntawa mai inganci{0}: Ana inganta fasahar sabunta jika koyaushe, musamman tare da ci gaban fasahar sarrafa ruwa, yana sa aikace-aikacensa ya fi dacewa.
Haɗa kayan aiki da aiki da kai: Haɗa murkushewa, sabuntawa, kawar da ƙura, sufuri, da sarrafawa cikin tsari ɗaya don rage aikin ƙasa da ma'aikata.
Jaddada kariyar muhalli da amfani da albarkatu: Manufar ita ce a cimma "sifirin hayaki" na tsohon yashi da sake amfani da ruwa. Lokacin shirya kayan aiki, ana ba da shawarar samun zurfafa sadarwa tare da ƙwararrun masu samar da kayan aikin simintin gyaran kafa. Dangane da tsarin samfuran ku, ƙarar samarwa, kasafin kuɗi na saka hannun jari da yanayin rukunin yanar gizon, keɓance mafi dacewa mafita na sarrafawa musamman don bukatunku.
