Chii ichocho zvidhina zvinokanganisa zvinokandwa zvekupisira marara?

Tsvina yekupisira marara yakakamurwa kuita: munispaine yakasimba tsvina yekupisa, intermittent incinerator, grate-type dream incinerator, marara pyrolysis gasification incinerator, fluidized bed incinerator, rotary kiln-mhando yeindasitiri tsvina incinerator, grate-mhando yekupisa choto.

Nemhaka yokuti kune marudzi akawanda emarara ayo asingakwanisi kunyatsogadziriswa, kukosha kwekoriori yemarara yakasiyanawo. Kuti uve nechokwadi chekuti incinerator yemarara inochengetedza kushanda kwakanaka pasi pekushisa kwepamusoro kwenguva refu, zvakakosha kufunga nezvekusarudzwa kwezvinhu zvinoramba kubva kune zvakawanda. Kunyanya silicon carbide zvidhinha. Zvigadzirwa zvinonyanya kuumbwa nevhu-yakavakirwa, yakakwirira-aluminium mapurasitiki, ivhu-yakavakirwa, uye silicon carbide-based castables. Nekuda kwehuori hwakanyanya hwekupisa marara, kushandiswa kwezvinokandwa kunogara kuchishanduka. Kushandiswa kwesilicon carbide castables uye phosphates yakasanganiswa nepamusoro-aluminium castables iri kuwedzera zvishoma nezvishoma nokuti idzi mbiri dzakakandwa dzine kumira kwakanaka kwekupfeka.

Nheyo yekusarudza yezvinhu zvinoramba: marara akasiyana-siyana ane mamiriro ekushanda akasiyana, uye kupisa kwemukati kwakasiyana-siyana kunoda zvinhu zvakasiyana-siyana zvezvinhu zvinoramba. Naizvozvo, refractory zvinhu zvine akasiyana zvivakwa zvinofanirwa kusarudzwa zvinoenderana nekwavanogara nharaunda uye tembiricha yekushandisa. Iyo tembiricha yekushandisa yemuchina wekupisa marara ndeye 1200 ℃-1400 ℃. Iyo gasi inoparadza zvakanyanya kuzvinhu zvinoramba panguva yekupisa, uye pasi pechoto, mapropeller, uye madziro eparutivi zvakasakara uye zvinokanganiswa. Nokudaro, kusarudzwa kwepamusoro-soro lining icharamba ichivandudzwa.

Sarudza refractory zvinhu zvinoenderana nenharaunda yekushanda. Muchikamu chekupinza chetsvina yemarara, sezvo kupinza uye kudonha kwemarara kunofanirwa kunge kwakabatana nezvinhu, uye tembiricha yechiteshi chekuisa inochinja kazhinji, iyo refractory inodiwa kuve nekupfeka kwakanaka kwekupokana uye kupisa kutyisa kuramba. Nokuda kwekugadzikana, zvidhinha zvevhu zvinogona kushandiswa.

Mukamuri yekuomeswa uye mukamuri yekupisa yekupisa tsvina, marara uye chigadziko chevira zvinosangana zvakananga pakupisa kwakanyanya. Kune rumwe rutivi, slag ichanamatira kumucheka wechoto, uye kune rumwe rutivi, tsvina ichapinda mukati mechoto. Panguva imwecheteyo, kuiswa kwemarara kuchaita zvisingadzivisiki kuchinja kwekushisa. Naizvozvo, zvinhu zvinoramba zvichidikanwa kuti zviite kwete kungopfeka-kusagadzikana, kusaora, uye kunetsa kunamatira, asiwo alkali-resistant uye oxidation-inodzivirira. Kazhinji, zvidhinha zvevhu, yakakwirira-aluminium zvidhinha, SiC zvidhinha, castables uye mapurasitiki anoshandiswa.

Sarudza zvinhu zvinoramba zvichienderana nekushisa kwekushandisa, zvakasiyana-siyana zvekupisa marara, nzvimbo dzakasiyana dzekushandisa, uye tembiricha dzakasiyana dzekushandisa: tembiricha yekushandisa padenga, madziro emadziro, uye zvinopisa zvekamuri yekupisa ndeye 1000-1400, uye refractoriness ye1750-1790. inogona kusarudzwa. High-alumina zvidhinha uye zvidhinha zvevhu, mapurasitiki ane refractoriness ye1750-1790 anogonawo kushandiswa.

Zvinodiwa zve refractory zvinhu zvinofanirwa kuve nemapoinzi anotevera:

1. Shandisa zvigadzirwa zvepamusoro-simba uye zvisingapfekeki kuti urambe kupfeka uye mhepo yakasimba;

2. Inofanira kuva neacid resistance uye kugadzikana kuti irambe iine acid corrosion;

3. Thermal shock zvakare chinhu chakakosha chisingagoni kuregererwa;

Chechina, inofanira kuva neCO erosion kudzivirira iyo lining material kubva pakutsemuka;

Chechishanu, kusarudzwa kwezvinhu zvekudzivirira, maererano nemamiriro akasiyana-siyana, sarudza chiedza chekudzivirira zvinhu zvinonyanya kukodzera chikamu chimwe nechimwe.
