II. Wuraren Aiki guda uku na Desulfurization Absorber

Ana iya raba abin sha zuwa sassa uku na aiki daga sama zuwa ƙasa: oxidation crystallization, absorption and demisting zone.

(1) Oxidation crystallization zone yana nufin slurry pool na absorber, kuma babban aikinsa shi ne narkar da farar ƙasa da oxidize calcium sulfite.

(2) Yankin sha ya haɗa da mashigai mai ɗaukar abin sha, tire da yadudduka na feshi. Akwai bututun mazugi da yawa akan kowane Layer na na'urar fesa; Babban aikin abin sha ya dogara ne akan gurɓataccen acidic da kuma shayar da toka a cikin iskar hayaƙi.

(3) Yanki mai lalata yana da ɓarna mai matakai biyu sama da feshin. Babban aikinsa shine ya raba digo a cikin iskar hayaki, rage tasirin kayan aiki na ƙasa da adadin abin sha.

Wurin shayar da abin sha yana nufin wurin da ke tsakanin tsakiyar layin mashigai na abin sha da na mafi girman Layer feshi. Ruwan da aka fesa yana wanke iskar hayaƙi mai ɗauke da sulfur a wannan yanki. Isasshen tsayin yanki na sha yana tabbatar da ƙimar desulfurization mafi girma. Mafi girma da tsawo, ƙananan da ake bukata wurare dabam dabam famfo kwarara kudi A karkashin wannan bukata a kan desulfurization kudi.

An ayyana yankin fesa na abin sha kamar:

(1) Hasumiya mai fesa: 1.5m ƙasa mafi ƙanƙanta bututun ƙarfe zuwa wurin fitarwa na mafi girman bututun ƙarfe.

(2) Hasumiyar ginshiƙi mai ruwa: daga madaidaicin bututun ƙarfe zuwa 0.5m sama da ginshiƙin ruwa mafi girma lokacin da duk famfunan zazzagewa suna gudana.

The absorber ne core na'urar na flue gas desulfurization tsarin. Yana buƙatar babban yanki mai lamba gas-ruwa, kyakkyawan halayen iskar gas, ƙananan asarar matsa lamba. Ya dace da maganin iskar gas mai ƙarfi. Ana kammala matakan aiwatarwa na farko a wannan na'urar:

① Zubar da iskar gas mai cutarwa a cikin wanke slurry;

② Rabuwar iskar hayaki da slurry na wankewa;

③ Neutralisation na slurry;

④ Oxidation na tsaka-tsakin samfurori na tsaka-tsaki a cikin gypsum;

Ƙirƙirar gypsum crystallization.

III. Abun shayarwa

Gabaɗaya ana raba mai ɗaukar shuɗi zuwa silinda, mai shigar da bututun hayaƙi da mashin iskar hayaƙi a cikin tsari. Mai shigar da bututun hayaƙin hayaƙi da magudanar ruwa suna kwance a tsakiyar abin sha kuma a saman abin sha kamar yadda aka saba. Ana iya raba Silinda mai ɗaukar hoto zuwa tafkin slurry, Layer feshi da yanki mai lalacewa a cikin aiki. Wurin slurry yana a ƙasan ɓangaren mashigai mai ɗaukar hoto gabaɗaya, kuma faifan fesa da na'urar da ake kashewa suna tsakanin mashin iskar hayaƙin hayaƙi da mashigar. Tushen bututun hayaƙi na abin sha na iya zama babban kanti kai tsaye ko madaidaicin gefe.

Wurin fesa na al'ada yana fasalta yadudduka na feshi da nozzles da sauran na'urori. Dangane da tsarin desulfurization, yankin SPRAY na wasu abubuwan sha za a kuma sanye su da trays, sandunan Venturi da sauran na'urori.

IV. Bukatun ƙira don Absorber

(1) Matsakaicin alli-sulfur kada ya wuce 1.05.

(2) Lokacin amfani da hasumiya mai hasumiya, saurin iskar gas ɗin mai ɗaukar iska a ƙarƙashin yanayin ƙira bai kamata ya wuce 3.8m/s ba, wanda za'a iya sa ido ta hanyar Coriolisfƙanananhaduer.

(3) Haɗe-haɗen tsarin tafkin slurry kuma an fi son jikin hasumiya.

(4) Lokacin zama na slurry wurare dabam dabam kada ya zama kasa da 4 min, da kuma ruwa shafi hasumiya ya kamata ba kasa da 2.5 min.

(5) Ya kamata a sanya zoben riƙon ruwa da murfin ruwan sama a mahadar bututun hayaƙi mai ɗaukar ruwa da bangon mai ɗaukar hoto a tsaye.

(6) Ya kamata a shirya bututun hayaƙin hasumiya mara komai a cikin hanyar shiga ƙasa. Lokacin da aka karɓi tsarin shigarwa a kwance, ya kamata a tabbatar da cewa mafi ƙarancin matsayi na hayaƙin a gwiwar hannu na farko kusa da mashigai na abin sha ya kasance sama da 1.5 zuwa 2m sama da matakin ruwa na yau da kullun na wurin tafki mai slurry. Za a iya shirya bututun bututun hasumiya mai ɗorewa ta hanyar shiga a kwance ko a tsaye.

(7) Nisa tsakanin madaidaicin yadudduka na feshin hasumiya mara kyau bai kamata ya zama ƙasa da 1.8m ba.

(8) Ya kamata saman saman feshin hasumiya na feshin fanko ya kamata ya fesa ƙasa kawai, kuma tazarar tazarar daga mafi ƙanƙanta Layer na demister kada ta kasance ƙasa da 2m.

(9) Don hasumiya mai feshi sanye take da tire-kurai da tabulators, tire-tinn da tabulator ya kamata a yi su da kayan hana lalata.

(10) Lokacin da shaye gas dumama da zafi musayar na'urar ba a shigar, da selection na zane sigogi kamar fanko hasumiya ya kwarara kudi, ruwa-gas rabo, da kuma slurry m abun ciki na absorber ya kamata la'akari da bukatun desulfurization yadda ya dace da kuma tasiri na dalilai kamar rage yawan net flue gas droplets dauke.

(11) Ya kamata a daidaita ƙirar mai ɗaukar hoto zuwa ƙirar ƙirar tukunyar tukunyar jirgi da abun ciki na sulfur na kwal. Mai hankaliwanda ba na nukiliya baslurry yawa meterdagaLonnmeterana ba da shawarar don saka idanu da yawa na farar ƙasa da gypsum a kan hanyar don ba da garantin isassun ƙimar desulfurization.
