Wāhanga tango warowaihā taumaha whāngai hau
1）Mahi pūnaha
Ka totoka hoki ngā warowaihā taumaha me ngā warowaihā kakara i roto i te hau māori i te pāmahana iti, nō reira me tango atu. Ka whakamahia e te waeine te tikanga mimiti waro whakahohe hei tango i ngā warowaihā taumaha me ngā warowaihā kakara.
I tēnei wāhanga, e rua ngā pourewa mimiti rite tonu e whakamahia ana hei mimiti i ngā warowaihā taumaha me ngā warowaihā kakara. Ka whakamahia te tikanga TSA hei tātari i ngā warowaihā taumaha me ngā warowaihā kakara i roto i te waro whakahohe. I taua wā anō, ka whakamahia te tikanga whakapūtā hei whakapūtā me te wehe i ngā warowaihā taumaha me ngā warowaihā kakara kua tangohia mai i te mea mimiti.
2）Ngā tawhā hoahoa
Te kaha tukatuka hau whāngai 10 × 104Nm3 / rā
Pēhanga mimiti 4.4MPa.G
Te wāhi hoahoa o te warowaihā taumaha i roto i te hau whāngai ≤ 1000ppmv
Te pāmahana mimiti ~ 40 ℃
Pēhanga whakaora 4.2MPa.G
Te pāmahana whakaora 180 ~ 280 ℃
Hinu whakawhiti wera pāmahana teitei pūtake wera whakaora
Ko te nui o te warowaihā taumaha me te warowaihā kakara i roto i te hau parakore me ≤ 10ppm ia.
3）Te whānuitanga o te urutau
Ko te awhe whakahaere kawenga he 50 ~ 110%.
4）Whakaahuatanga rere o te tukanga
Ka tomo tuatahi te hau māori mai i te wāhanga whakamaroke hau whāngai mai i te tihi o te pourewa tango waro taumaha mā te takirere whakahaere pēhanga rerekē. Whai muri i te tangohanga o te waro taumaha mā te mimiti o te moenga waro whakahohe, ka puta mai i te raro o te pourewa tango waro taumaha. Whai muri i te tangohanga o te waro taumaha, ko te ihirangi o te waro kakara i roto i te hau māori he ≤ 10ppmv, kātahi ka tomo ki te wāhanga tango me te tātari puehu.
E rua ngā pourewa tango warowaihā taumaha o te wāhanga tango warowaihā taumaha. I roto i tētahi huringa mimiti, kei roto tētahi i te āhua mimiti hei tango i ngā warowaihā taumaha i roto i te hau whāngai, ā, kei roto tētahi i te āhua whakaora (whakamahana me te pupuhi matao) hei tango i ngā warowaihā kakara i roto i te waro whakahohe. Ina kua mākū te pourewa tango warowaihā taumaha i te āhua mimiti, huri ki te pourewa tango warowaihā taumaha e whakaoti ana i te whakaora. Whai muri i te pourewa tango warowaihā taumaha mākū, ka whakamahanahia te huringa whakaora, kātahi ka whakamatao.
Ka tangohia te hau whakaora mai i te taha mua o te takirere whakahaere pēhanga rerekē. Ka tomo te hau whakaora ki te oumu whakamahana hau whakaora, ā, ka whakamahanatia ki te 220 ~ 280 ℃. Ka mimitihia e te hau wera me te hau maroke ngā hauwaiwaro kakara i roto i te waro whakahohe mai i runga ki raro mā te pourewa tango hauwaiwaro taumaha whakaora (whakamahana). Ka tomo te hau whakaora kei roto ngā hauwaiwaro kakara mai i te pourewa tango hauwaiwaro taumaha i te āhua whakaora (whakamahana) ki te pouaka whakamatao hau whakaora hei whakamatao tonu, kātahi ka wehea ngā hauwaiwaro kakara kua whakakōpiripiritia pea i roto i te wehewehe, ā, ka tomo te wai kua whakakōpiripiritia ki te wehewehe hau wahie.
Ka tomo te hau mai i te tihi o te wehewehe hau whakaora ki te pourewa mimiti i te āhua mimiti me te hau maori whāngai i muri i te takirere whakahaere pēhanga rerekētanga.
Whāngai hau waeine tango me te tātari mercury
1）Whakaahuatanga tukanga
Ka uru te hau māori mai i te wāhanga whakamaroke hau whāngai me te tango warowaihā taumaha ki roto i te kaihoroi waro whakahohe kua whakakiia ki te whanariki. Ka tauhohe te mekuri ki te whanariki i runga i te waro whakahohe kua whakakiia ki te whanariki hei whakaputa i te mekuri whanariki, ka mimitihia ki runga i te waro whakahohe, kia tutuki ai te kaupapa o te tango mekuri. Ko te ihirangi mekuri o te hau māori mai i te tango mekuri he iti iho i te 0.01μg/Nm3.
Kotahi te tango mercury ka whakatakotoria, ā, ka whakakapia te waro whakahohe kua whakakiia ki te whanariki e ai ki te kitenga.
Kei te wae tātari he tātari, ka taea te whakawhiti kia rite ki ngā raraunga ātete hei whakatutuki i te kaupapa o te tātari i te tatari ngota me te puehu waro whakahohe.
I muri i te tango puehu, ko te matotoru o ngā matūriki puehu i roto i te hau whāngai he iti iho i te 10μm.
Ko ngā taputapu matua he tango mercury me te tātari puehu.
