Kuchenesa nzira yeceramic foam sefa

Ceramic foam sefa inogona kunyatso kupinza inclusions musimbi yemvura uye kuvandudza kunaka kwekukanda uye goho, ceramic furo sefa ine nzira ina huru dzekunatsa simbi yemvura.
(1) Inoyangarara yekuparadzanisa michina
Mushure mekuisa iyoceramic furo sefamuhurongwa hwekudurura, kushorwa kwemvura yesimbi kuyerera kunowedzera, uye simbi yemvura mudururu system izere nehurumende, kuitira kutamba iyo slag inovharira basa rekudurura system. Panguva imwecheteyo, kuyerera kwemvura kwakaiswa jekiseni kubva kune yakatwasuka sprue inoputirwa kuburikidza nesefa, iyo simbi yemvura inogara kwenguva pfupi mune yakatwasuka sprue, uye slag ine diki density inoyangarara kumusoro uye inoparadzanisa, iyo inogona kuburitsa yakafanana mhedzisiro yejekiseni repasi. kudira hurongwa. Kana iyo simbi yemvura ichipfuura nepakati
Ceramic foam sefa kuti ienderere mberi nekudurura, kune rumwe rutivi, kuwanda kweiyo diki slag inoyangarara, kune rumwe rutivi, zvinobudirira kuderedza kana kubvisa eddy ikozvino.
(2) "Cake filter" nzira
Ceramic furo sefayakakomberedzwa chiteshi, inogona kuita inoshanda mechanical slag kuvharira, yakawanda yakakura kupfuura gomba resefa mune slag entrapment inobatwa kumagumo ekupinda kwesefa. Nekuwedzera kwenhamba yeakabatwa inclusions, mufirita inlet kuguma kwepamusoro pekugadzirwa kwezvidimbu zvakakura zvemukati zvinogadzirwa ne "filter cake". Iyo "keke" inoita kuti mvura inoyerera iite mutete, kuitira kuti inclusions idiki pane saizi yesefa inobatwawo mu "keke".
(3) Adsorption mechanism
Sefa yakaiswa mugomba remuchinjikwa chiteshi kana chemukati sprue, kusefa kusefa kwakadzika, apo tambo yekutanga yesimbi yakanyungudutswa inosvika painopinza yekupedzisira pamusoro pesefa, zvichikonzera kuyerera kwemvura uye furo mesh adsorption phenomenon, panguva imwe chete. nguva, kuyerera kwemvura kuchaitika "impact" chiitiko, iyo sefa pachayo ine inovharira mhedzisiro, zvimwe zvehutsvina mune imwe dzvinyiriro, nekuda kwe tsvina uye yakasimba foam ceramic mesh. Zvimwe zvinosanganisirwa pasi peimwe dzvinyiriro, nekuda kwekuiswa uye yakasimba foam ceramic mesh furemu yakafanana ne "common grid correspondence" hukama, kuitira kuti zvive nyore kuisa mafuta uye adsorption, iyi adsorption inonyanya kusarudzika yakawanda-molecular layer yemuviri. adsorption ndicho chinhu chikuru, inclusions mune sefa mesh furemu adsorption layer ne layer, kusvika pakavharika.
(4) Kugadzirisa maitiro
Kana iyo simbi yakanyungudutswa ichiyerera kuburikidza neceramic furo sefa, inokamurwa kuita zvidimbu zvidiki zvekuyerera kwetambo, uye dhayamita yaro idiki, kuitira kuti nhamba yeReynolds (Re = vD/γ) ive diki, kuitira kuti kuyerera kwemvura kuite. kuti laminar kuyerera. Kana iyo simbi yemvura iri mu laminar kuyerera mamiriro, nekuda kwehutsi hwesimbi yakanyungudutswa yakakura kwazvo kupfuura density ye inclusions, kuitira kuti inclusions ine nguva yakakwana yekuyangarara kubvisa, saka iyoceramic furo sefainogona zvakare kubatsira muchinjika-yakakandwa chiteshi slag ichivharira, kudira sisitimu mushure mekuisa iyo sefa, iyo yemvura simbi inoyerera kuramba ichiwedzera, mumuchinjiko-wakakanda chiteshi mukuyerera kwesimbi yemvura iri nyore kugadzira kuyerera kuzere, uye kuita iyo mwero wekuyerera wakaderera, unoenderana nekuyangarara kweiyo inclusions uye inochengeterwa muPamusoro pepamusoro pemuchinjiro-wakakanda chiteshi.
