Ukuphelelwa yigesi okumanzi kwe-flue nge-lime / limestone slurry

Izici

• Ukusebenza kahle kokususelwa ngaphezulu kwe-99% kungatholakala
• Ukutholakala kwama-98% angatholakala
• Ubunjiniyela obuncike kunoma iyiphi indawo ethile
• Umkhiqizo ongathengiswa
• Ukusebenza kwengxenye okungenamkhawulo kwengxenye
• Indlela enenombolo enkulu yezethenjwa emhlabeni

Izigaba zenqubo

Izigaba ezibalulekile zenqubo yale ndlela emanzi yokuhlaselwa yile:

• Ukulungiselela okumunwe kanye ne-dosing
• Ukususwa kwe-Sox (HCL, HF)
• Enze uthathe isimo somkhiqizo

Ngale ndlela, i-limestone (caco3) noma i-Quicklime (CAO) ingasetjenziswa njenge-munbent. Ukukhethwa kwesengezo esingangezwa omile noma njengoba kwenziwa i-slurry ngesisekelo semibandela yemingcele eqondene nephrojekthi. Ukususa i-Sulfur oxides (Sox) nezinye izinto ze-acidic (HCL, HF), igesi ethambile ilethwa ekuxhumaneni okujulile nge-slurry equkethe isengezo endaweni yokutholwa. Ngale ndlela, indawo enkulu kunazo zonke engaphezulu yenziwe yatholakala ngokudluliselwa ngobuningi. Endaweni yokutholwa, i-SO2 kusuka kugesi ye-flue iphendula ngokumunca ukwenza i-calcium Sulphite (Case3).

I-limestone slurry equkethe i-calcium sulphute iqoqwe esihlahleni se-Absorber. I-limestone esetshenziselwa ukuhlanza amagesi we-flue ngokuqhubekayo ingezwe kwisigaxa se-absorber ukuqinisekisa ukuthi umthamo wokuhlanza we-absorber uhlala njalo. Ama-slurry avele athengwe endaweni yokutholwa futhi.

Ngokushayisa umoya esibayeni esisingenwe, i-gypsum yakhiwa kusuka ku-calcium sulphite futhi isuswa kwinqubo njengengxenye ye-slurry. Ngokuya ngezidingo ezisezingeni lomkhiqizo wokugcina, okwenziwa okwengeziwe ukwenziwa ukukhiqiza i-gypsum ethengisayo.

I-Plant Engineering

Ekuhlathembeni kwegesi okumanzi kwe-flue,, i-open tower tower abathathwe yizingxenye ezihlukaniswe izindawo ezimbili eziphambili. Lezi yindawo yokutholwa evezwa igesi ephukile kanye ne-absorber sump, lapho i-limestone slurry ibhajwa futhi iqoqwe. Ukuvimbela ama-deposits kwisigaxa se-absorber, ama-slurry amiswe ngezinqubo zokuxuba.

Igesi ebibangelo igeleza ibe yi-absorber ngenhla kweleveli yoketshezi bese idlula indawo yokutholwa, okuhlanganisa amazinga wokufafaza ngokweqile kanye nomlimi we-mist.

I-limestone slurry emunxusiwe kwisigaxa se-absorber isfafazwe kahle njengamanje namanje ku-counter-okwamanje kugesi we-flue ngokusebenzisa amazinga wokufafaza. Ukuhlelwa kwama-nozzles embhoshongweni wokufafaza kubalulekile ekusebenzeni kahle kwe-absorber. Ukusebenza kahle kokugeleza ngakho-ke kunesidingo esikhulu. Ku-Eliminator ye-Mist, amaconsi athwalwa endaweni yokutholwa yigesi ye-flue abuyiselwe kwinqubo. Esikhathini sokuphuma kwe-absorber, igesi ehlanzekile igcwele futhi ingasuswa ngokuqondile nge-coolling tower noma isitaki esimanzi. Ngokuzithandela igesi ehlanzekile ingashisa futhi iqondiswe esitaki esomile.

I-slurry ekhishwe kwi-absorber swerber ikhuphuka izothonya lokuya phambili nge-hydrocyclones. Ngokuvamile leli slurry langaphambi kokugxila liye lakhiwa ngokulandelana ngokuhlunga. Amanzi, atholakala kule nqubo, angabuyiselwa enkulu kwi-absorber. Ingxenye encane isuswa kwinqubo yokujikeleza kwetoreji ngesimo sokugeleza kwamanzi okungcola.

Ukususwa kwegesi kwe-Flue kuzitshalo zezimboni, izitshalo zamandla noma imfucumfucu yokufakelwa kwezitshalo kuncike kuma-nozzles aqinisekisa ukusebenza okuqondile esikhathini eside nesikhathi eside futhi kubekezelela izimo zemvelo ezinolaka kakhulu. Ngezinhlelo zalo ze-nozzle, i-Lecler inikezela ngezixazululo ezingochwepheshe nezisuselwa ku-application for Spray Scrubber noma ama-Sprape
