Indlela ye-Steam Boiler Blowdown
Kunezindlela ezimbili eziphambili zokufakelwa kwama-boilers kaSteam, okungukuthi kubekwe phansi okuphansi kanye nokuqhuma okuqhubekayo. Indlela yokukhuculiswa kwendle, inhloso yokukhishwa kwendle kanye nokufakwa kokufakwa kwalokhu okubili kuhlukile, futhi ngokuvamile ngeke bakwazi ukuthatha isikhundla.
Ukuqhuma okungezansi, okwaziwa nangokuthi isikhathi se-blowdown esinqunyelwe, ukuvula i-valve enkulu ye-paimeter engezansi kwe-boiler imizuzwana embalwa ukushaya phansi, ukuze kufakwe inani elikhulu lamanzi embiza. . Le ndlela iyindlela ekahle yokubulala, engahlukaniswa yaba yi-Manual Control kanye nokulawula okuzenzakalelayo.
Ukuqhuma okuqhubekayo kubizwa nangokuthi Blowdown Engaphezulu. Ngokuvamile, i-valve isethwe ohlangothini lwe-boiler, futhi inani lendle lilawulwa ngokulawula ukuvulwa kwe-valve, ngaleyo ndlela elawula ukugcwala kwama-terwoli ancibilikisiwe.
Kunezindlela eziningi zokulawula ukushaya kwe-boiler, kepha into yokuqala okufanele icatshangwe iyinhloso yethu ngqo. Eyodwa ukulawula ithrafikhi. Uma sesibalile ukuthi i-blowdown iyadingeka ku-boiler, kufanele sinikeze izindlela zokulawula ukugeleza.

Amathegi Omkhiqizo

Amapharamitha esiwaziyo ukuthi: IVolumu yokukhucululwa kwendle, ingcindezi yokusebenzisa i-boiler, ngaphansi kwezimo ezijwayelekile, ingcindezi yokwehla kwendle yemishini yokukhucululwa kwendle ingaphansi kuka-0.5barg ingaphansi kuka-0.5barg. Usebenzisa la mapharamitha, usayizi we-orifice ukwenza umsebenzi ungabalwa.
Olunye udaba okufanele lubhekiswe lapho ukhetha imishini yokulawula e-Blowdown ilawula ukwehla kwengcindezi. Izinga lokushisa lamanzi elikhishwe kusuka ku-boiler lingamazinga okushisa agqisune, futhi ukucindezela kwethonya ngokusebenzisa i-orifice kusondelene nengcindezi yamanzi, okusho ukuthi ingxenye enkulu yamanzi izokhula ibe umusi wesibili, futhi ivolumu yalo izonyuka ngezikhathi eziyi-1000. USteam uhamba ngokushesha kunamanzi, futhi njengoba kungekho sikhathi esanele somusi namanzi okuhlukana, amaconsi amanzi azophoqeleka ukuba ahambe noSteam ngesivinini esikhulu, okuvame ukucekela phansi kubizwa ngokuthi umdwebo we-orifice. Umphumela uba yi-orifice enkulu, ekhipha amanzi amaningi, futhi amandla awohloka. Ingcindezi ephakeme, inkinga ecace kakhudlwana kamusi wesibili.
Njengoba inani le-TDS litholwa ngezikhathi ezithile, ukuze liqinisekise ukuthi inani le-TDS lamanzi e-boiler phakathi kwezikhathi ezimbili zokuthola, ukuvulwa kwe-orifice kumele kukhuphuke ukwedlula ukuhwamuka okuphezulu kwenani le-boiler lokuthuthwa kwendle okukhishwe.
I-National Standard GB1576-2001 ehlukanisa ukuthi kunobudlelwano obuhambisanayo phakathi kokuqukethwe usawoti (okuhlanjululwe okuqinile) kwamanzi e-boiler kanye nokusebenza kukagesi. Ku-25 ° C, ukuthuthuka kwamanzi wethayela lokungathathi hlangothi kungu-0.7 ama-TDS (okuqukethwe usawoti) wamanzi othando. Ngakho-ke singakwazi ukulawula inani le-TDS ngokulawula ukuvumelanisa. Ngokulawula isilawuli, i-valve ye-drain ingavulwa njalo ukuze icishe ipayipi ukuze amanzi okugoqa agelezele inzwa ye-TDS, bese kuthi isibonakaliso sokusebenza esitholwe yi-TDS Sensor ukufaka isilawuli se-TDS futhi siqhathaniswa nesilawuli se-TDS. Setha inani le-TDS ngemuva kokubalwa, uma liphakeme kunenani elisethiwe, vula i-TDS control valve ukuze i-blowdown, bese uvala i-valve kuze kube yilapho ama-tds e-boiler atholayo (okuqukethwe usawoti) kuphansi kunenani elibekiwe.
Ukuze ugweme imfucuza ye-blowdown, ikakhulukazi lapho i-boiler ikule eceleni noma umthwalo ophansi, isikhathi sokuphumula phakathi kokugcwala ngakunye sihlobene ngokuzenzakalelayo nomthwalo weSteam ngokuthola isikhathi esivuthayo se-boiler ngokuthola isikhathi esivuthayo se-boiler. Uma ngaphansi kwephuzu elisethiwe, i-blowdown valve izovala ngemuva kwesikhathi esimnandi futhi ihlale kuze kube yilapho i-flush elandelayo.
Ngoba uhlelo lwe-othomathikhi lokulawula lwe-TDS lunesikhathi esifushane sokuthola inani le-TDS yenani lamanzi esithando kanye nokulawulwa inani lamanzi esithando lingase liseduze nenani elivumelekile. Lokhu akugcini nje ngokugwema ukufakwa komusi kanye nokwehla ngenxa yokuhlushwa okuphezulu kwe-TDS, kepha futhi kunciphisa ukushaya kwe-boiler futhi kusindisa amandla.
