Lipompo bakeng sa Limestone-gypsum wet FGD (Flue Gas Desulfurization) Process

Ⅰ. Molao-motheo

SO2 ke e 'ngoe ea lintho tse ka sehloohong tse silafatsang moea le sesupo sa bohlokoa sa taolo ea tšilafalo ea khase e litšila ea indasteri Chaena. Hajoale, likarolo tsohle tsa mochini o fehloang ka mashala naheng ea China li kentse tšebetsong merero ea ho tlosa khase ea flue, eo har'a eona theknoloji e ka sehloohong ea desulfurization e leng limestone/gypsum wet flue gas desulfurization (WFGD). Ts'ebetsong ena, slurry ea lejoe la mokoetla e sebelisoa e le ntho e monyang, e kopanang le khase ea flue toreng ea desulfurization ebe e tsoakana ka ho feletseng. Ka mor'a hore SO2 ka khase ea flue e sebetsane le monyezi, ka lik'hemik'hale e itšoara ka moea oxidizing o fefoloang ke fan ea oxidizing ho etsa gypsum.

 

Ho na le tanka e seretse ka tlase ho tora ea ho monya, 'me mokelikeli o mocha o pompeloa ka tanka ea seretse ka pompo ea lejoe la mokoetla e fepang seretse; tlas'a mosebetsi oa agitator, e kopantsoe le slurry e teng ka tanka ea slurry; ka nako eo, slurry potoloha pompo tla phahamisa slurry e tsoakiloeng ho lera spray le fafatsa ho theosa ho kopana le khase ea flue phallo khahlanong le hona joale. Ho tlatsoa ka nepo le ka nako ea monyo o mocha ke oa bohlokoa ts'ebetsong eohle. Haeba chelete ea tlatsetso e sa lekana, ho thata ho netefatsa katleho ea desulfurization; haeba chelete ea tlatsetso e phahame haholo, e tla fokotsa sekhahla sa ts'ebeliso ea monyetla, 'me e ama boleng ba lihlahisoa tsa desulfurization. Ka hona, taolo ea pompo ea lejoe la mokoetla ke karolo ea bohlokoa ea ts'ebetso ea FGD.

 

Ⅱ. Lipompo tse hlokoang ke tsamaiso ea ho sebetsa

1. Sistimi ea ho lokisa lejoe la mokoetla

2. Pompo bakeng sa tsamaiso ea tora ea ho monya

3. Tsamaiso ea khase ea flue

4. Pompo bakeng sa tsamaiso ea ho ntša metsi ka gypsum

5. Lipompo tsa tsamaiso ea ho ntša metsi

6. Lipompo tsa tsamaiso ea ho hloekisa metsi a litšila

 

Ntle le tsamaiso ea khase ea flue, mekhoa e ka holimo e tla hloka lipompo tsa slurry. Ka tsamaiso ea tora ea ho monya, molumo oa ente o batla o le moholo, kahoo bophara ba pompo bo batla bo le boholo. Lipompo tse karolong ena ke lipompo tse khethehileng tse khethehileng tse etselitsoeng ho tlosoa ha sulfurization, 'me lipompo tse sebelisoang lits'ebetsong tse ling ke lipompo tsa rona tse nyenyane le tse mahareng tse sebelisoang hangata. Ho ea ka boemo ba slurry, thepa e khethiloeng ea likarolo tsa phallo ha e na ho apara le ho senya.
