Desiccants bụ ihe na-amịkọrọ mmiri ma ọ bụ mmiri.Enwere ike ime nke a site na usoro abụọ dị iche iche:
A na-etinye mmiri mmiri n'anụ ahụ;a na-akpọ usoro a adsorption
A na-ekekọta mmiri mmiri ahụ;a na-akpọ usoro a absorption
Ụdị desiccant a na-ahụkarị na-arụ ọrụ alumina, sieve molecular, alumina silica gel.
Adsorbent (ntụnyere olu mgbasa ozi ọnụego mgbasa ozi)
Olu mgbasa ozi:
Alumina silica gel> silica gel> molecular sieve> alumina arụ ọrụ.
ọnụego mgbasa ozi: sieve molecular> aluminasilica gel> silica gel> alumina arụ ọrụ.
Gwa anyị ihe nchekwa mmiri gị chọrọ, anyị ga-akwadokwa desiccant kwesịrị ekwesị.Ọ bụrụ na ngwaahịa gị ma ọ bụ ihe akpakọtara chọrọ oke mmiri dị ala, ọ kacha mma iji sieves molecular.Ọ bụrụ na ngwongwo gị adịchaghị enwe mmetụta nke mmiri, onye na-eji silica gel desiccant ga-eme ya.
① Adsorbent n'ime mmiri, ike mkpakọ na-ebelata, ndochi adịghị ike
② usoro nrụgide nha nha adịghị ma ọ bụ gbochie ya, mmetụta dị oke ibu
③ iji ndochi mkpanaka na-akpali akpali, na-emetụta ike mkpakọ nke ngwaahịa ahụ
Alumina arụ ọrụ: 160°C-190°C
Sive ihe omimi: 200°C-250°C
Alumina silica gel na-eguzogide mmiri: 120°C-150°C
Usoro mgbako: na-ejuputa QTY = njuputa olu * nnukwu njupụta
Ka ihe atụ, otu set generator = 2M3 * 700kg / M3 ＝ 1400kg
JZ-CMS4N ịta nitrogen mmepụta bụ 240 M3 / ton na ndabere 99.5% N2 ịdị ọcha, Ya mere, otu setịpụrụ N2 mmepụta ikike bụ = 1.4 * 240 = 336 M3 / h / set
PSA O2 usoro: pressurized adsorption, ikuku desorption, Anyị nwere ike iji JZ-OI9, JZ-OI5
VPSA O2 usoro: ikuku adsorption, agụụ desorption, Anyị nwere ike iji JZ-OI5 na JZ-OIL ụdị
