I-Ultrasonic Bandast Water Delinfection Uhlelo Lokwelashwa Kwe-Ultrasonic

Amanzi we-ballast we-ultrasonic ukwelashwa ngezinto eziphilayo zasolwandle zingahlukaniswa ngezigaba ezintathu ezilandelayo

• Ukukhula okuthambile okufana nezipanji;
• Amagciwane kanye ne-single - amaselula aphilayo, njengezinhlobo ezahlukahlukene zamagciwane kanye ne-algae;
• Izilwane ezinzima zasolwandle, njengezigidi, ama-molluscs we-bivalve, njll.

-Philile
Umsindo ungachazwa njengamandla emishini adluliselwa amagagasi wengcindezi endaweni ephakathi nendawo. Ngakho-ke, umsindo ungachazwa njengendlela yamandla noma umsindo kuthiwa ungumshini. Lokhu kuhlukanisa amandla azwakalayo kwakha ezinye izinhlobo zamandla, njengamandla kagesi. Le ncazelo ejwayelekile ifaka zonke izinhlobo zomsindo, kufaka phakathi umsindo ozwakalayo, okuphansi - Imvamisa amagagasi avelelayo (i-infrasound), ne-ultrasound.

Inkanyezi
I-Ultrasound yingcindezi yomsindo we-cyclic ovame kakhulu kunomkhawulo ophezulu wokuzwa komuntu. Yize lo mkhawulo umehluko kusuka kumuntu uye kumuntu, kucishe kube ngu-20 kilohertz (20,000 hertz) kubantu abadala abaphilile, abancane futhi ngenxa yalokho, u-20 KHZ usebenza njengomkhawulo ophansi owusizo ekuchazeni i-ultrasound.

Izicelo ze-Ultrasound
Izicelo zamanje ze-ultrasound zifaka ngokwesibonelo: I-Sonochemistry (emulsation, ukusheshisa kokuphendula kwamakhemikhali, ukukhishwa kwamagesi we-microscopic, ukususwa kwamagesi abhalwe phansi, futhi ngokuvamile ukungenela okuphakathi nendawo noma ukukala amandla agxile. Isiginesha yokukhombisa singaveza imininingwane ngesakhiwo sangaphakathi se-medium. Uhlelo lokusebenza oluhle kakhulu lwale ndlela ukusetshenziswa kwalo ku-Sonography ukukhiqiza izithombe zezingane esibelethweni somuntu. Olunye uhlelo lokusebenza lusebenzisa i-ultrasound ekuxilonwe umdlavuza.

Izinombolo zohlelo lokusebenza lwe-ultrasound ziningi. Ukuhlanganisa amaza afanele, amplitude ofanele futhi asebenzisa i-transducer efanelekile izinhlobo eziningi zohlelo lokusebenza lwe-ultrasound zingatholakala ... 'isibhakabhaka umkhawulo' ...

Amabutho e-ultrasound
Ukudalula uketshezi kumagagasi aphezulu okucindezela (noma amaza azwakalayo), amabutho njengokusakazwa kwe-acoustical, ukuhanjiswa okuzinzile kanye ne-cavitation (kungazinzile noma i-insertial) cavitation.

Isibonelo, ukuhlukaniswa kwe-ultrasonic, i-sonochemissence kanye ne-sonoluminescence kuvela e-acoustic cavitation: ukwakheka, ukukhula nokuwohloka okufaka ama-bubble ku-uketshezi. Ukuwa kweCavitational kukhiqiza ukufudumeza kwasendaweni okukhulu (~ 5000 k), izingcindezi eziphakeme (~ 1000 ATM), kanye namazinga amakhulu okushisa namazinga okupholisa (> 10 9 k / sec). I-Acoustic Cavitation ihlinzeka ngokuxhumana okuyingqayizivele kwamandla kanye nendaba, kanye ne-ultrasonic irradiation of ketshezi kudala ukusabela kwamakhemikhali wamandla aphezulu okwenzeka, kuvame ukuhambisana nokuphuma kokukhanya.

Lokhu kungatholakala kuphela esimweni esithile esihilela amaza athile aphezulu wamandla we-ultrasound (aphezulu we-W • cm - 2, i-DB ephezulu) evezwe amanani aphansi okushisa aphansi.
