Physical khoom, Standard tej yam kev mob P = 101325 Pa, T = 273,3 K
- Ceev ntawm ozone: 2,14 kg / m 3
- Molecular luj ntawm ozone: 48
- Ceev ntawm oxygen: 1.43 kg / m 3
- Molecular luj ntawm oxygen: 32
- Ceev ntawm huab cua: 1.29 kg / m 3
- Ceev dej: 1,000 kg / m 3
Pab Conversion yam: (rau cov dej)
- 1,000 litres = 1 m 3 = 264 US taub
- 1 gal = 3,785 litres = 3.785 ml
- 1 m 3= 35.3 ft 3 = 264 US Gallons
Nws Concentration nyob rau hauv Dej
- 1 mg / l = 1 ppm O 3 = 1 g O 3/ m 3 dej {By hnyav}
Nws Concentration nyob rau hauv huab cua By Volume
- 1 g O 3 / m 3 = 467 ppm O 3
- 1 ppm O 3 = 2.14 mg O 3/ m 3
- 100 pphm (qhov chaw rau ib puas vam) = 1 ppm (qhov chaw rau ib lab)
Nws Concentration nyob rau hauv huab cua los ntawm Nyhav
- 100 g O 3/ m 3 = 7.8% O 3 (kwv lam)
- 1% O 3 = 12.8 g O 3/ m 3 (kwv lam)
- 1% O 3 = 7,284 ppm Nws
Nws Concentration nyob rau hauv cov pa los ntawm Nyhav
- 100 g O 3/ m 3 = 6.99% O 3 (kwv lam)
- 1% O 3 = 14.3 g O 3/ m 3 (kwv lam)
- 1% O 3 = 6,520 ppm Nws
Txiav txim Nws ntau npaum nyob rau hauv Dej
Cov mis yog tiag heev yooj yim.
Nws yog dej flowrate x ozone ntau npaum = yuav tsum ozone ntau lawm
LWM taub hau YOG TSEEM CEEB HEEV
Hauv qab no yog cov mis rau kev txiav txim ozone tiam yuav tsum yog koj paub ntau dej thiab ozone tsis (namely flowrate nyob rau hauv gpm thiab ozone ntau npaum nyob rau hauv mg / l).
- flowrate (gpm) x 3,75 l / gal x 60 min / hr x ozone ntau npaum (mg / l) = ozone ntau lawm (mg / hr)
Cia ua hauj lwm los ntawm ib qho piv txwv. Yuav ua li cas npaum li cas ozone ntau lawm yog yuav tsum tau mus txhaj koob tshuaj 2 ppm rau hauv 20 gpm dej? (peb yuav tau siv ppm thoob plaws hauv lub so ntawm qhov kev piv txwv paub hais tias 1 mg / l = 1 ppm)
20 gpm x 3,75 l / gal x 60 min / hr x 2 ppm = 9.084 mg / hr (9 gm / hr)
Nco ntsoov hais tias 9 gm / hr tso cai rau koj mus rau koob tshuaj rau cov dej uas muaj 2 ppm ntawm ozone. Qhov no tsis tau txhais hais tias 2 ppm yuav yog koj zaum kawg yaj ozone concentration. Vim efficiency losses nrog txhaj ozone thiab ozone thov ntawm cov dej, koj yaj ozone concentration yuav tsawg dua.
Txiav txim seb cov qhov tso zis ntawm ib tug ozone generator
cov mis yog flowrate (lpm) x ozone concentration (g / m 3 ) = ozone ntau lawm (mg / hr)
Wb ua hauj lwm los ntawm ib qho piv txwv: Lub ozone concentration tawm ib ozone generator yog 120 g / m 3 ntawm 5 lpm ntawm oxygen txaus. Yuav ua li cas yog cov qhov tso zis?
5 l / min x 120 g / m 3 x (1 m 3/ 1,000 l) = 0.60 g / min
g / min yog tsis zoo rau lwm nyob rau hauv lub ozone kev lag luam ces peb tsuas hloov feeb rau cov sij hawm kom tau g / hr: 0,60 g / min x 60 min / hr = 36 g / hr
qauv pauv hloov
Hloov 140 g / m 3 rau wt% (oxygen feedgas).
raws li nyob rau hauv lub hloov dua siab tshiab saum toj no, 100 g / m 3 = 6.99 wt. %
yog li ntawd 140 g / m 3 /100 g / m 3 x 6.99 wt. % = 9.8 wt.%
