I-Ultrasonic Ballast Water Disinfection Inkqubo yonyango lwe-ultrasonic

Unyango lwe-Ultrasonic Ballast Amanzi Izinto eziphaphayo zaselwandle zinokwahlulwa zibe zezi ndidi zintathu zilandelayo

• Ukukhula okuthambileyo okufana neziponji;
• Iibhaktheriya kunye neseli enye yezinto eziphilayo, ezifana neentlobo ezahlukeneyo zebhaktheriya kunye ne-algae;
• Izilwanyana zaselwandle ezinzima, ezinje ngeebarnacle, ii-bivalve molluscs, njl.

Isandi
Isandi sinokuchazwa njengamandla oomatshini ahanjiswa ngamaza oxinzelelo kwinto ebonakalayo. Ke, isandi sinokuchazwa njengohlobo lwamandla okanye isandi kuthiwa sisenziwa ngoomatshini. Oku kwahlula uhlobo lwamandla esandi nezinye iindlela zamandla, ezinje ngombane wombane. Le nkcazo ngokubanzi ibandakanya zonke iindidi zesandi, kubandakanya isandi esivakalayo, amaza enyikima asezantsi kakhulu (infrasound) kunye ne-ultrasound

I-Ultrasound
I-Ultrasound ingcinezelo yesandi ejikelezayo engaphezulu komda ophezulu weendlebe zabantu. Nangona lo mda uhluka ukusuka komnye umntu uye komnye, umalunga ne-20 kilohertz (i-20,000 hertz) esempilweni, abantu abadala abancinci kwaye ke, i-20 kHz isebenza njengomda osezantsi oluncedo ekuchazeni i-ultrasound.

Izicelo ze-Ultrasound
Ukusetyenziswa okwangoku kwe-ultrasound kubandakanya umzekelo: i-sonochemistry (i-emulsification, ukukhawulezisa kweekhemikhali, ukususwa njl.njl.) Ukusasazeka, kunye nokuphazamiseka kweeseli zebhayiloji (ukutshatyalaliswa kwe-ultrasonic), ukususwa kweegesi ezibanjisiweyo, ukucoca ukungcola kwe-microscopic, i-ultrasonic humidifier, i-ultrasound identification (USID ), kwaye ngesiqhelo ukungena kumbindi kunye nokulinganisa utyikityo lokuboniswa okanye ukubonelela ngamandla. Ukutyikitywa kokubonisa kunokuveza iinkcukacha malunga nolwakhiwo lwangaphakathi lwaphakathi. Esona sicelo saziwayo sobu buchule kukusetyenziswa kwesonografi ukuvelisa imifanekiso yemveku esibelekweni somntu. Esinye isicelo sisebenzisa i-ultrasound ekuchongeni isifo somhlaza.

Amanani esicelo se-ultrasound maninzi. Ukudibanisa amaza alungileyo, ubungakanani obuchanekileyo kunye nokusebenzisa i-transducer elungileyo iintlobo ezininzi zesicelo se-ultrasound sinokufezekiswa… 'Isibhakabhaka sisiphelo'…

Imikhosi ye-Ultrasound
Ukuveza ulwelo kumaza oxinzelelo aphezulu oomatshini (okanye amaza esandi), amandla okusasazeka kwe-acoustical, ukuzinza okuzinzileyo kunye nokudlula okwethutyana (okungazinzanga okanye okungafakwanga ngaphakathi) kungenziwa.

Umzekelo wokuchithwa kwe-ultrasonic, i-sonochemistry kunye ne-sonoluminescence zivela kwi-acoustic cavitation: ukuyilwa, ukukhula, kunye nokuwa okungafunekiyo kwamaqamza kulwelo. Ukuwa kwe-Cavitational kuvelisa ukufudumeza kwendawo (~ 5000 K), uxinzelelo oluphezulu (~ 1000 atm), kunye namaqondo aphezulu okufudumeza kunye nokupholisa (> 10 9 K / sec). I-acoustic cavitation ibonelela ngokudibana okungafaniyo kwamandla kunye nomba, kwaye i-ultrasonic irradiation yotywala ibangela amandla aphezulu eekhemikhali ukuba avele, ihlala ihamba kunye nokukhutshwa kokukhanya.

Oku kunokufikelelwa kuphela kwimeko ethile ebandakanya amaza ombane aphezulu e-ultrasound (i-W ephezulu ye-cm-2, i-dB ephezulu) evulelekileyo kumthamo wolwelo olusezantsi kakhulu lobushushu obuphantsi.
