Mhepo inosvibisa kubva mukugadzira simende uye mhinduro dzakakodzera.
Mhepo inosvibisa kubva mukugadzira simende inonyanya kuve huruva uye gasi reflue.
Iyo huruva inonyanya kuuya kubva kune zvinotevera maitiro:
1.the raw materials kugadzirira
A.CaCO3 kupwanya.
B.Clay kuomesa
C.Marasha ekukuya nekudyisa.
D.Kudya mbishi kukuya.
2.Clinker inopfuta hurongwa ichapedza yakawanda huruva mhepo.
3.Kupedza kugadzira kugadzirisa:
A. Zvigayo zvesimende
B.Kurongedza simende
C. Iyo yakawanda simende yekufambisa.
Kune yekugadzira zvinhu zvakasvibirira A, C, D uye yekupedzisa kugadzirwa kwemhepo yeguruva inouya neiyo yakaderera tembiricha, asi iyo mbishi kugadzirira B, guruva mhepo inonetesa kubva mumusoro nemuswe wechoto inogara ine tembiricha yepamusoro.
Zvimedu zviri mumhepo yeguruva zvakanyanya CaCO3,CaO,SiO2,Fe2O3,Al2O3,MgO,Na2O,K2O, nezvimwe.
Nokuti flue gasi kubva simende kugadzirwa zvikurukuru SO2, NOx, CO2, HF, uye zvichingodaro inobva kuora CaCO3 uye mafuta kupisa.
SO2 inobva mukudya mbishi (dema kana hafu yeupfu yakasvibira yehupfu yehuni yakatwasuka), kupisa mafuta;
NOx iyo inobva mukuita pakati peN2 neOxygen mukupisa kwepamusoro;
HF inobva mukuumbwa kwefluorine inoora kubva pachikafu chakasvibira kana kupisa maitiro, sekusanganisa nefluorite seminerarizer mumoto wakatwasuka.
CO2 inonyanya kubva mukuora kweCaCO3, kupisa kwehuni, nezvimwe.
Mhinduro:
1.For the dust air control
Zonel filtech inogona kupa iyo sefa bag guruva muunganidzi kuti ichenese mhepo, zvakare inogona kupa zvinoenderana nezvinodiwa nevatengi.
Iyo bhegi mafirita kubva kuZonel filtech ine yakanyanya kusefa kunyatsoshanda, kunyangwe kune iyo 0.5 micron zvimedu, iyo sefa inoshanda inogona kusvika 99.99%, uye mafirita anogara aine kuita kwakagadzikana, ari nyore kwazvo kugadzirisa.
Zonel brand bag sefa imba inogona kuunganidza huruva isingabatwe necottrell, senge guruva rine yakanaka kwazvo kana yakaipa kwazvo conductivity.
2.For the flue gasi kudzora
CO2: kuvandudza kunaka kwe clinker; kuderedza kushandiswa kwe clinker, sekugadzira zvimwe zvekusanganisa zvinhu pahwaro hwezvinhu zvakafanana zvesimende, shandisa imwe simende yakasvibira inotsiva kuderedza kushandiswa kwesimende; gadzira masisitimu ari nani ekushandisa kupisa kwemarara, sekushandisa kupisa kwemarara kuomesa zvinhu, shandisa kupisa kwemarara kugadzira magetsi, nezvimwe.
SO2:
Shandura zviri nani mbishi, deredza iyo Sulfur yemukati;
Inotorwa pazvigayo zvakasvibirira: tungamira mhepo yeguruva kubva kumuswe wechoto kuenda kune yakasvibira zvigayo, maitiro seanotevera:
CaCO3 + SO2 = CaSO3 + CO2
2 CaCO3 + 2 SO2 + O2 = 2 CaSo4 + 2 CO2
Sanganisa imwe Ca(OH)2;
Shongedza shongwe yekugeza;
Uye iyo inonyanya kushanda mhinduro inosarudza yakakodzera Sulfur uye alkali chikamu;
Panguva imwecheteyo, pamuswe wechoto, shongedza mabhegi mabhegi muunganidzi weguruva, iyo Na2O, K2O iri pamusoro peguruva sefa mabhegi ichaita neSO2 uye NO2, zvirimo mumhepo asidhi zvinogona kuderedza 30 ~ 60. %.
NOx:
Chengeta tembiricha yakakodzera, chengetedza huwandu hwemhepo;
Shandisa gasi rinoderedza, rakadai seCO, H2, nezvimwewo, sanganisa mamwe Fe2O3, Al2O3 pakudya mbishi, izvo zvinogona kuderedza NOx kuN2.
2NO + 2CO = N2 + CO2;
2NO + 2H2 = N2 + 2H2O
2NO2 + 4CO = N2 + 4 CO2
2NO2 + 4H2 = N2 + 4H2O
Zvinoenderana nechiito, saka pachoto unofanirwa kudzora zvirimo zveO2 nekungwarira.
Sarudzo inokonzeresa kuderedza zvakare inogona kubatsira kuderedza iyo NOx kuneta, mhinduro iyi kuisa imwe yakasarudzika inoderedza, senge hydrogen nitride kana Urea:
8NH3 + 6NO2 -> 7N2 + 12H2O
6NO + 4NH3 -> 5N2 + 6H2O
4NH3 + 3O2 -> 2N2 + 6H2O
Yakarongedzwa neZONEL FILTECH
