He paipa ātete-mau me te hydrocyclone kei roto i ngā tipu hiko he mea whakakikorua ki te uku silicon carbide.
Ngā Pūnaha Paipa Ukume Silicon CarbideTe Whakahou Anō i ngā Hanganga o te Whare Hiko
He tino uaua ngā mahi a ngā whare whakaputa hiko, ā, e mau tonu ana ngā pūnaha paipa:
- Huringa wera tonu (100–650°C)
- Ngā tere matūriki whakakoi neke atu i te 30 m/s
- ngā rerekētanga pH mai i te 2–12 i roto i ngā mīhini horoi hau paru
- Ngā piki me ngā heke o te pēhanga huringa (0–6 MPa)
He maha ngā wā ka pakaru ngā paipa whakarewa me ngā paipa polymer tuku iho i raro i ēnei āhuatanga, ā, ka waiho ko ngā paipa ātete-kakahu uku silicon carbide (SiC) te otinga hangarau mō ngā tipu hiko o ēnei rā.
Te Aranga o te Pūtaiao Rauemi
Ka whakakotahi ngā paipa uku SiC i ngā āhuatanga ahurei e tika ana mō ngā tono o te rāngai pūngao:
- Te pakeketanga o Vickers 28 GPa (4× te pakeketanga atu i te tungsten carbide)
- Te Auau Whakamau <0.1 mm³/N·m (ASTM G65)
- Te Awe Wera 120 W/m·K (pai ake i te maitai kore waikura)
- Te Ātete Matū (ātete ki te 98% H₂SO₄ i te 300°C)
Ngā Painga Whakahaere i roto i ngā Pūnaha Tino Hira
1. Te Whakahaere Waro me te Kawe Pungarehu
- Ka ātete ki te pakarutanga o te waikura 5–7 mm/tau mai i te 60% o te paru totoka
- Kia mau tonu te whakahekenga rere i raro i te 5% i roto i ngā hāora mahi 10,000
2. Te Whakakorenga o te Hau Kohu (FGD)
- Te mahi ātete-pH i roto i ngā ara iahiko paru kōhatu
- Whakakorehia te waikura i puta mai i te hauota
3. Te Kawe i te Pungarehu Rere
- 0.08 μm te taratara o te mata ka whakaiti i te piri o te matūriki
- Ka taea te whakahaere i te kaha 50 tana ia hāora i ngā koki piko 35°
Te Huringa Ōhanga
Ka ripoatahia e ngā kaiwhakahaere tipu ngā painga ka taea te ine:
- 70% te hekenga o ngā whakakapinga paipa kāore i whakamaheretia
- 55% te iti iho o ngā utu mahi tiaki
- 18% te pai ake o te pai o te wera i roto i ngā huringa mamaoa
- 40% te roa o te ora o te pūnaha, ki te whakataurite ki ngā momo koranu kē atu
Te Ngāwari o te Tāutanga me te Whakahaere
- Ngā wāhanga ā-whakarerekē 1–6 m me ngā hononga ā-flanged/miro
- 60% te whakaiti taumaha ki ngā mea ōrite o te maitai (3.2 karamu/cm³ te mātotoru)
- Ka taea te tāpiri ki ngā tautoko paipa me ngā whakairi o nāianei
- Hototahi ki ngā pūnaha aroturuki atamai mō te matapae kākahu
Ngā Auahatanga e Arotahi ana ki te Ao Tūroa
Ko ngā otinga paipa SiC o te whakatipuranga e whai ake nei e whakauru ana i:
- Te pūngao ā-pūngao hei whakaiti i te ahotea wera
- Ngā momo kawe hiko mō te whakatōtō hiko
- Ngā hononga uku-elastomer ranu mō te whakaiti i te wiri
- Ngā kakano nano o te mata e horoi ana i a ia anō
Mai i ngā tipu waro ki ngā whare para-ki-te-pūngao, ka tautuhi anō ngā paipa uku silicon carbide i te pono o ngā hanganga hiko. Ko tā rātou huinga ahurei o te ātete miihini, te manawanui wera, me te pumau matū ka whakarite kia haere tonu te mahi i raro i ngā āhuatanga tino kino - ka huri i ngā wā tiaki mai i ngā whakatikatika tauhohe ki ngā whakapainga kua whakaritea, he utu-pai.
Ko Shandong Zhongpeng Special Ceramics Co., Ltd tētahi o ngā otinga rauemi hou uku silicon carbide nui rawa atu i Haina. Uku hangarau SiC: Ko te pakeke o Moh he 9 (ko te pakeke o Moh hou he 13), he ātete pai ki te horo me te waikura, he ātete pai ki te pakū me te ārai-waikura. Ko te roa o te ora ratonga o te hua SiC he 4 ki te 5 ngā wā roa atu i te rauemi alumina 92%. Ko te MOR o RBSiC he 5 ki te 7 ngā wā i tō SNBSC, ka taea te whakamahi mō ngā āhua uaua ake. He tere te tukanga whakatau utu, ko te tuku e rite ana ki te mea i oatitia, ā, ko te kounga kāore he rite. Ka tohe tonu mātou ki te wero i ā mātou whāinga me te tuku i ō mātou ngākau ki te hapori.
