Mafirita anowanzo reva zvinhu zvinozadzwa mune zvimwe zvinhu.
Muchiinjiniya chemakemikari, kurongedza kunoreva inert yakasimba zvinhu zvakaiswa mushongwe dzakazara, senge Pall mhete neRaschig mhete, nezvimwewo, iyo basa nderekuwedzera gasi-mvura yekubata kumeso uye kuita kuti vasanganise zvakasimba pamwe chete.
Muzvigadzirwa zvemakemikari, mafirita, anozivikanwawo semafirita, anoreva zvinhu zvakasimba zvinoshandiswa kuvandudza mashandiro, michina yezvigadzirwa uye/kana kuderedza mitengo.
Mumunda wekutsvaira kwetsvina, inonyanya kushandiswa mukubata oxidation process, uye ma microorganisms anounganidza pamusoro peiyo filler kuti awedzere kusangana kwepasi netsvina uye kushatisa sewage.
Zvakanakira: chimiro chakareruka, kudonhedza kudiki, nyore kugadzira ne-corrosion-resistant non-metallic materials, etc. Yakanakira kupfekwa kwegasi, vacuum distillation uye kubata kwezvinwiwa zvinopisa.
Zvakaipa: Kana shongwe mutsipa ichiwedzera, inokonzeresa kugoverwa kwegasi uye mvura, kusabatana kwakashata, zvichingodaro, zvichikonzera kudzikira kwekuita, kunonzi amplification effect. Panguva imwecheteyo, shongwe yakarongedzwa ine zvisizvo zvehuremu hunorema, kudhura kwakanyanya, kunetsa kuchenesa nekugadzirisa, uye kurasikirwa kukuru kwekurongedza.
1.Pall ring packing
Iyo Pall mhete yekurongedza ndeye kunatsiridza paRaschig mhete. Mitsara miviri yemakona emahwindo emakona akavhurwa pamadziro emadziro eRaschig mhete. Rumwe rutivi rwemadziro akachekwa emadziro achiri kubatanidzwa kumadziro, uye rumwe rutivi rwakakotamira mumhete. , kuumba chipande chemutauro chinobuda nechomukati, uye mativi erukova rwemutauro anopindirana pakati pemhete.
Nekuda kwekuvhurwa kwemadziro mhete yePall mhete, chiyero chekushandisa chemukati nzvimbo uye mukati meiyo mhete inovandudzwa zvakanyanya, kupikisa kwemhepo kudiki, uye kugovera kwemvura kwakafanana. Kuenzaniswa neRaschig mhete, iyo gasi inoyerera yePall mhete inogona kuwedzerwa neanopfuura 50%, uye hukuru hwekufambisa hunobudirira hunogona kuwedzerwa ne30%. Pall ring ndiyo inoshandiswa zvakanyanya kurongedza.
2. Nhanho mhete kurongedza
Iyo yakatsikwa mhete kurongedza igadziriso pamusoro pePall mhete nekudzikisira kureba kweiyo yakatsikwa mhete nepakati uye nekuwedzera tapered flange kune imwe mugumo uchienzaniswa nePall mhete.
Nekuda kwekuderedzwa kwechikamu chechikamu, nzira yepakati yegasi yakatenderedza madziro ekunze ekurongedza inopfupikiswa zvakanyanya, uye kushorwa kwegasi inopfuura nepakati pekurongedza kunoderedzwa. Iyo tapered flanging haingowedzere simba remagetsi ekuzadza, asi zvakare inoita kuti mafirita ashanduke kubva pamutsara wekubata kusvika pakubata, izvo zvisingango wedzera nzvimbo pakati pemafirita, asi zvakare inova nzvimbo yekuunganidza uye yekuparadzira kuti mvura iyerera ichitevedza pamusoro pekuzadza. , iyo inogona kukurudzira kuvandudzwa kwepamusoro kwefirimu yemvura, iyo inobatsira pakuvandudzwa kwehuwandu hwekufambisa kushanda.
Kuita kwakazara kwemhete yakatsikwa kuri nani pane iyo yePall ring, uye yave yakanyanya kunaka yeannular packings inoshandiswa.
3. Metal saddle kurongedza
Mhete yekurongedza (inozivikanwa seIntalox kunze kwenyika) imhando nyowani yekurongedza yakagadzirwa uchifunga nezvehunhu hwe annular uye saddle zvimiro. Iko kurongedza kunowanzo gadzirwa nesimbi, saka inodaidzwa zvakare kunzi simbi mhete saddle packing.
Annular saddle packing inobatanidza mabhenefiti e annular kurongedza uye chirairo kurongedza, uye kuita kwayo kuzere kuri nani pane iyo yePall mhete uye yakatsikwa mhete, uye inoshandiswa zvakanyanya mukurongedza kwakawanda.
