Ukomiswa okwenziwe ngokhuni

Ukomisa okwenziwayo kwenziwa emakamelweni okomisa akhethekile futhi kwenziwa ngokushesha kakhulu kunokomiswa kwemvelo. Igumbi lokumisa liyindawo evaliwe yokuma kwe-rectangular, lapho umoya ushiswa khona ngamashubhu akhethekile okuthiwa ama-ribbed tubes, lapho ajikeleza khona umusi, ongena kuwo usuka ekamelweni lokubilisa. Ezikomeni zegesi, izinto zomiswa ngamagesi aphuma ekamelweni elivuthayo kusetshenziswa idivayisi ekhethekile,
Umswakama ohwamuka okhunini ugcwalisa umoya, ngakho-ke uyasuswa esomisini, futhi umoya omusha, onomswakama omncane ulethwa endaweni yawo ngokusebenzisa imigudu ekhethekile yokuhlinzeka. Ngokomgomo wokusebenza, ama-dryer ahlukaniswe abe yilawo asebenza ngezikhathi ezithile nalawo asebenza ngokuqhubekayo.

Kuma-dryers asebenza ngezikhathi ezithile (umkhiwane 19), impahla ibekwe ngesikhathi esisodwa. Ngemuva kokumisa, izinto ezisetshenziswayo zisuswa esomisini, ukukhishwa kwe-steam kumshini wokushisa kuyamiswa, futhi iqoqo elilandelayo lezinto zokomisa ligcwele.
 Isitshalo esomisa, esisebenza ngokuqhubekayo, siqukethe iphasishi elilodwa elifinyelela ku-36 m ubude, lapho ama-wagonettes anempahla emanzi engena ngakolunye uhlangothi, kanye nama-wagonette anento eyomisiwe ashiye ngakolunye uhlangothi.
Ngokusho kwemvelo yokunyakaza komoya, ama-dryer ahlukaniswe abe yilawo anomjikelezo wemvelo, okwenzeka ngenxa yoshintsho lwesisindo esithile somoya esomisweni, kanye nama-dryer ane-pulse circulation, ezuzwa ngumdlali oyedwa noma ngaphezulu.

Sl. 19 Isomisi esisebenza ngezikhathi ezithile ngokujikeleza kwamanzi emvelo 

Imishini yokomisa esebenza ngokuqhubekayo ihlukaniswe yaba okokomisa ukugeleza kwe-counter-flow - lapho umoya wethulwa ukuze uhlangabezane nokunyakaza kwento eyomiswayo, kanye ne-co-flow dryer - uma isiqondiso sokunyakaza komoya oshisayo sifana nesiqondiso sokunyakaza impahla, kanye nalabo abasebenza nge transverse air kwegazi, lapho ukunyakaza komoya oshisayo umoya wenziwa isiqondiso perpendicular ukunyakaza impahla (fig. 20).

Sl. 20 Umshini wokomisa onokuzungeza komoya ongemuva okuqinile; 1 - fan, 2 - radiators,

3 - iziteshi zokuhlinzeka, 4 - iziteshi zokudonsa

Uma ijubane lokunyakaza komoya ku-dryer, elidlula into eyomiswa, lidlula i-1 m / sec, khona-ke lolu hlobo lokumisa lubizwa ngokuthi ukusheshisa. Uma, ngesikhathi somisa, umoya oshisayo odlula into eyomiswa, ushintsha indlela yokuhamba, futhi isivinini saso sidlula i-1 m / sec, khona-ke lokhu kunyakaza kubizwa ngokuthi ukunyakaza okuphambene, futhi amadivaysi okomisa abizwa ngokuthi ama-dryers ane-accelerated, reverse air circulation. .
Kumadryer anomjikelezo wemvelo, isivinini somoya esidlula impahla esomisiwe singaphansi kuka-1 m/sec.
Amabhodi aqediwe* noma izinto eziqedwe kancane zingomiswa. Amabhodi okufanele omiswe apakishwe ezinqoleni (umkhiwane 21).

Sl. 21 izinqola eziyisicaba

Amapulangwe amade kufanele apakishwe ezinqoleni eziyisicaba (fig. 21). Ama-slats omile anogqinsi lwama-22 kuya ku-25 mm nobubanzi obungama-40 mm asetshenziswa njengamaphedi. Ama-coasters abekwe ngaphezulu komunye ukuze enze umugqa oqondile (umkhiwane 22). Inhloso yamaphedi ukudala izikhala phakathi kwamabhodi ukuze umoya oshisayo udlule ngokukhululeka kudlule izinto ezomisiwe futhi kukhishwe umoya ogcwele umhwamuko wamanzi. Izikhala phakathi kwemigqa eqondile yamaphedi zithathwa ngamabhodi anobukhulu obungu-25 mm - 1 m, amabhodi anobukhulu obungu-50 mm - 1,2 m. Amaphedi kufanele abekwe ngaphezu kwemishayo ephambene - kuthiwani ku-wagonette.

Sl. 22 Indlela yokupakisha izingodo ezisaha ukuze zomiswe kuyilapho kugcinwa amabanga alungile phakathi kwamaphedi

Ukuhleleka okungahleliwe kwamaphedi kungabangela ukuvunguza komoya kwezingodo ezisahwe. Emaphethelweni amabhodi, ama-pads kufanele ahambisane nezinhlangothi zangaphambili zamabhodi noma abe ne-overhang encane, ukuze avikele amaseli ekugelezeni okukhulu komoya oshisayo. Uma izingxenye ezikhiqiziwe zomisiwe, zifakwa ezinqoleni ezinamaphedi enziwe ngezingxenye ngokwazo, ubukhulu obungama-20 kuya ku-25 mm kanye nobubanzi obungama-40 kuya ku-60 mm. Ibanga phakathi kwemigqa eqondile yamacansi akufanele ibe ngaphezu kuka-0,5 - 0,8 m.
