Malo ophatikizira konkire a asphalt (omwe amatchedwanso kuti phula) ndi chida chofunikira pomanga misewu yayikulu. Zimaphatikiza matekinoloje osiyanasiyana monga makina, magetsi, ndi kupanga maziko a konkriti. Pakali pano, pomanga mapulojekiti a zomangamanga, kuzindikira kwa anthu za chitetezo cha chilengedwe kwawonjezeka, kutetezedwa kwa mphamvu ndi kuchepetsa utsi kumalimbikitsidwa, komanso kuzindikira za kukonza zinyalala zakale ndi kubwezeretsanso zinyalala zawonjezeka. Choncho, machitidwe ndi chikhalidwe cha zipangizo zochotsera fumbi muzitsulo za asphalt sizingogwirizana mwachindunji ndi ubwino wa kusakaniza kwa asphalt. Ubwino, ndikuyika patsogolo zofunikira zaukadaulo wa opanga zida ndi kuzindikira kwa magwiridwe antchito ndi kukonza kwa ogwiritsa ntchito zida.
[1]. Kapangidwe ndi mfundo ya zida zochotsera fumbi
Nkhaniyi ikutenga chomera cha phula cha Tanaka TAP-4000LB monga chitsanzo. Zida zonse zochotsera fumbi zimatengera njira yochotsera fumbi lamba, yomwe imagawidwa magawo awiri: kuchotsa fumbi la bokosi lamphamvu yokoka komanso kuchotsa fumbi la lamba. Makina owongolera ali ndi: fani yotulutsa mpweya (90KW * 2), valavu yowongolera mpweya wa servo motor, valavu yonyamula fumbi la lamba ndi valavu yowongolera solenoid. Wothandizira wamkulu limagwirira okonzeka ndi: chimbudzi, chimney, mpweya ngalande, etc. Kuchotsa fumbi mtanda gawo m'dera pafupifupi 910M2, ndi fumbi kuchotsa mphamvu pa unit nthawi akhoza kufika pafupifupi 13000M2/H. Kugwira ntchito kwa zida zochotsera fumbi kumatha kugawidwa m'magawo atatu: kulekanitsa ndi kuchotsa fumbi-kuyendetsa ntchito-kutulutsa fumbi (mankhwala onyowa)
1. Kulekanitsa ndi kuchotsa fumbi
Chotsitsa chopopera ndi servo motor air volume control valve imapanga kupanikizika koyipa kudzera mu tinthu tating'ono ta fumbi la zida zochotsera fumbi. Panthawi imeneyi, mpweya ndi fumbi particles umayenda pa liwiro lalikulu mwa bokosi yokoka, thumba fumbi wotolera (fumbi wachotsedwa), mpweya ducts, chimneys, etc. Pakati pawo, fumbi particles zazikulu kuposa 10 microns mu chubu. condenser kugwa momasuka pansi pa bokosi pamene iwo fumbi ndi bokosi yokoka. Tinthu tating'onoting'ono tochepera 10 ma microns amadutsa mu bokosi lamphamvu yokoka ndikukafika pachotolera fumbi la lamba, pomwe amamangiriridwa ku thumba lafumbi ndipo amapopedwa ndi mpweya wothamanga kwambiri. Kugwa pansi pa osonkhanitsa fumbi.
2. Ntchito yozungulira
Fumbi (tinthu tating'ono ting'onoting'ono ndi tinthu tating'onoting'ono) timene timagwera pansi pa bokosi pambuyo pochotsa fumbi limayenda kuchokera ku chotengera chilichonse cha wononga kukhala bin yosungiramo ufa kapena zobwezerezedwanso posungira ufa malinga ndi chiŵerengero chenichenicho chosakanikirana.
3. Kuchotsa fumbi
Ufa wobwezerezedwanso womwe umathamangira mu bin yowumbidwanso umatha fumbi ndikubwezeretsedwa ndi njira yonyowa yochizira.
[2]. Mavuto omwe alipo pakugwiritsa ntchito zida zochotsa fumbi
Pamene zidazo zinkagwira ntchito kwa maola pafupifupi 1,000, osati kutuluka kwa mpweya wotentha wothamanga kwambiri kuchokera ku chimney chosonkhanitsa fumbi, komanso kuchuluka kwa fumbi particles anaphunzitsidwa, ndipo woyendetsa anapeza kuti matumba a nsalu anali otsekedwa kwambiri, ndipo matumba ambiri a nsalu anali ndi mabowo. Palinso matuza papaipi ya jakisoni wa pulse, ndipo thumba la fumbi liyenera kusinthidwa pafupipafupi. Pambuyo kusinthanitsa luso pakati pa akatswiri ndi kulankhulana ndi akatswiri Japanese kwa Mlengi, izo anaganiza kuti pamene wotolera fumbi anachoka fakitale, fumbi wotolera bokosi anali olumala chifukwa cha zolakwika mu kupanga, ndi porous mbale wa wotolera fumbi anali olumala. ndipo sanali perpendicular kwa mpweya kuyenda jekeseni ndi chitoliro kuwomba, kuchititsa kupatuka. Mphepete mwa oblique ndi matuza pawokha paipi yowomba ndizomwe zimayambitsa thumba losweka. Ikawonongeka, mpweya wotentha wonyamula tinthu ta fumbi umadutsa mu fumbi-flue-chimney-chimney-atmosphere. Ngati kukonzanso bwino sikunachitike, sikungowonjezera kwambiri mtengo wokonza zida ndi ndalama zopangira zomwe kampaniyo imagulitsa, komanso kuchepetsa kupanga bwino komanso kukongola kwake ndikuipitsa kwambiri chilengedwe, ndikupanga kuzungulira koyipa.
[3]. Kusintha kwa zida zochotsera fumbi
Poganizira zolakwika zazikuluzikulu zomwe zili pamwamba pa chosonkhanitsa fumbi la asphalt, ziyenera kukonzedwanso bwino. Cholinga cha kusintha kwagawidwa m'magawo otsatirawa:
1. Sinthani bokosi lotolera fumbi
Popeza mbale ya perforated ya osonkhanitsa fumbi yakhala ikupunduka kwambiri ndipo silingakonzedwe kwathunthu, mbale ya perforated iyenera kusinthidwa (ndi mtundu wofunikira m'malo mwa mitundu yambiri yogwirizana), bokosi losonkhanitsa fumbi liyenera kutambasulidwa ndi kukonzedwa, ndipo mizati yothandizira iyenera kukonzedwa kwathunthu.
2. Yang'anani zigawo zina zowongolera za osonkhanitsa fumbi ndikuchita kukonzanso ndikusintha
Yang'anani mozama za jenereta ya pulse, valavu ya solenoid, ndi chitoliro chowombera fumbi, ndipo musaphonye zolakwika zilizonse. Kuti muwone valavu ya solenoid, muyenera kuyesa makinawo ndikumvetsera phokoso, ndikukonza kapena kusintha valavu ya solenoid yomwe sichita kapena kuchita pang'onopang'ono. Chitoliro chowombera chiyeneranso kuyang'aniridwa mosamala, ndipo chitoliro chilichonse chowombera chokhala ndi matuza kapena kutentha kutentha chiyenera kusinthidwa.
3. Yang'anani matumba a fumbi ndi zida zomata zolumikizira zida zochotsa fumbi, konzani zakale ndikuzibwezeretsanso kuti mupulumutse mphamvu ndikuchepetsa mpweya.
Yang'anani matumba onse ochotsa fumbi a otolera fumbi, ndikutsatira mfundo yoyendera "osasiya zinthu ziwiri". Wina sayenera kusiya thumba lafumbi lomwe lawonongeka, ndipo winayo sayenera kusiya thumba lafumbi lotsekeka. Mfundo ya "kukonza zakale ndikugwiritsanso ntchito zinyalala" iyenera kutengedwa pokonza thumba la fumbi, ndipo liyenera kukonzedwa potengera mfundo zopulumutsa mphamvu ndi kupulumutsa ndalama. Yang'anani mosamala chipangizo chosindikizira chosindikizira, ndikukonza kapena kusintha zisindikizo zowonongeka kapena zolephera kapena mphete za rabara mu nthawi yake.
