Parizvino, nzira yakajairika yekucheka pombi inoshandiswa nespiral steel pipe vagadziri ndeyekucheka kweplasma. Munguva yekucheka, huwandu hukuru hwesimbi mhute, ozone, uye nitrogen oxide hutsi huchagadzirwa, izvo zvinozosvibisa zvakanyanya nharaunda yakapoteredza. Kiyi yekugadzirisa dambudziko rehutsi inzira yekufemera utsi hwese hweplasma mumidziyo yekubvisa huruva kudzivirira kusvibiswa kwemhepo.

Kune plasma yekucheka kwespiral simbi mapaipi, matambudziko ekubvisa guruva ndeaya:
1. Mhepo inotonhora kubva kunharaunda yechiteshi chekusveta inopinda muchiteshi chekusveta ichibva kunze kwegeji remuchina uye vhoriyamu yemhepo yakakura kwazvo, zvichiita kuti huwandu hwese hwehutsi nemhepo inotonhora mupombi yesimbi ive yakakura kupfuura iyo inoshanda mhepo inofemerwa ne. iyo muunganidzi weguruva, zvichiita kuti zvisakwanise kutora zvachose utsi hwekucheka.
2. Iyo pfuti yeplasma inoputika mhepo mumativi maviri akatarisana panguva imwe chete panguva yekucheka, kuitira kuti utsi neguruva zvinobuda kubva kumativi ose epombi yesimbi. Zvisinei, zvakaoma kudzorera utsi uye guruva zvakanaka nechiteshi chekusveta chakaiswa mune imwe nzira yepombi yesimbi.
3. Sezvo chikamu chekucheka chiri kure neguruva rinopinza guruva, mhepo inosvika pakusveta inlet inoita kuti zvive zvakaoma kutamisa utsi neguruva.

Kuti izvi zviitike, misimboti yekugadzira yevacuum hood ndeiyi:
1. Mhepo yemhepo inoputirwa nemuunganidzi weguruva inofanira kuva yakakura kudarika huwandu hwehutsi uye guruva rinogadzirwa nekucheka kweplasma uye mhepo mukati mepombi. Humwe huwandu hwehudzvanyiriri husina kunaka hunofanirwa kuumbwa mukati mepombi yesimbi, uye huwandu hukuru hwemhepo yekunze haifanirwe kubvumidzwa kupinda mupombi yesimbi zvakanyanya sezvinobvira Kusveta utsi mumuunganidzi weguruva.
2. Vhara utsi uye guruva mushure mekucheka pombi yesimbi. Edza kudzivirira mweya unotonhora kupinda mukati mepombi yesimbi painopinza yekusveta. A negative pressure cavity inoumbwa munzvimbo yemukati yepombi yesimbi kudzivirira utsi neguruva kubva. Chinokosha ndechekugadzira zvivakwa zvekuvhara utsi neguruva. Yakagadzirwa yakavimbika, haina kukanganisa kugadzirwa kwakajairika, uye iri nyore kushandisa.
3. Chimiro uye nzvimbo yekuisa yekupinza inlet. Chiteshi chekusveta chinofanirwa kushandiswa kusveta hutsi hwakawanda uye guruva mukati mepombi yesimbi mupombi kuti iwane mhedzisiro. Wedzera bhanhire shure kwekucheka kwepfuti yeplasma kuti uchengetedze utsi uye guruva mukati mepombi yesimbi. Mushure menguva yebuffering, inogona kubviswa zvachose.

chiyero chaicho:
Isa chiputi cheutsi pane trolley mukati mepombi yesimbi uye uise iyo inenge 500mm kubva pakucheka kwepfuti yeplasma. Mira kwechinguva mushure mekucheka pombi yesimbi kuti utore utsi hwese. Ziva kuti chiutsi chinoputira chinoda kuiswa zvakanaka pachinzvimbo mushure mekucheka. Pamusoro pezvo, kuita kuti kutenderera kwetrolley inotsigira chiutsi uye pombi yesimbi zvienderane, kona yevhiri reinofamba yetrolley inofanira kuenderana nekona yeroller yemukati. Kune plasma yekucheka kwehombe-diameter spiral welded mapaipi ane dhayamita inosvika 800mm, iyi nzira inogona kushandiswa; kune mapaipi ane dhayamita isingasviki 800mm, utsi uye guruva rine madhayamita madiki haagone kubuda kubva munzira yekubuda kwepombi, uye hapana chikonzero chekuisa baffle yemukati. Zvisinei, pautsi hwekusveta inlet yepakutanga, panofanira kuva nebaffle yekunze kudzivirira kupinda kwemhepo inotonhora.
