1 Moden Envionmental Science and Engineeing (ISSN ) July 07, Volume 3, No. 7, pp Doi: 0.534/mese(333-58)/ /0 Academic Sta Publishing Company, 07 Development of Coona Ozonize Using High Voltage Contolling of Poduce Ozone Gas fo Cleaning in Cage Siseeot Ketkaew Faculty of Engineeing, Ramkhamhaeng Univesity, Huamak, Bangkapi, Bangkok, Thailand Abstact: This pape pesents development of coona ozonize using contolling fo cleaning in ed-whiskeed bulbul cage. This powe supply uses full-bidge convete at switching high fequency moe than 0 khz and contols its opeation using pulse width modulation (PWM) techniques. Powe MOSFET#IRFP450 is contolled by IC#TL494. The highly non-unifom electic field ozone tube of two level insulato cylindical. The testing of multi-ozone geneation system using 3 levels of contolling ae kv, 3 kv and 5 kv and at one-hou, ozone tube yields the ozone geneating capacity of 38 mgo 3 /h, 735 mgo 3 /h and 97 mgo 3 /h which ozone gas quantity ae 38 mgo 3 /h at 30 minute, 735 mgo 3 /h at 9 minute and 97 mgo 3 /h at minute enable cleaning in ed-whiskeed bulbul cage. Key wods: coona ozonize, cage, ozone gas, electic field, convete. Intoduction Nowadays, ozone gas is widely bought to use fo living such as using ozone to clean the vegetables instead of manganese to kill diseases and educe a quantity of chloine in wate. Binging ozone to clean the ai puely has some dawbacks. Fo examples, if it is used too much concentated, it can iitate to the body. It is useful to the health if quantity is popely used and is applied fo wok suitably. This pape pesents a study of the effect of adjustment using duty cycle contolling in Powe MOSFETs to the ozone quantity. The high fequency is constucted by using a pinciple of switching powe supply. A high fequency is supplied to the load, which ae two-laye electode in seies, fo poducing ozone gas. The geneating ozone gas is based on the pinciple of speading molecules of Coesponding autho: Siseeot Ketkaew, Ph.D., Associate Pofesso, eseach aeas/inteests: electical engineeing application fo envionmental, ozone application, electostatic ai cleane. siseeot@hotmail.com. oxygen. It will poduce ozone gas fom the equation of O + O = O 3 [-3].. Mateials and Methods The main facto of ai compises 79% nitogen (N ) and % oxygen (O ) []. The est is inet gas and steam. Ozone gas is the gas, consisted of 3 atom oxygen, unde unstable status, easy dispesion that is depended on the envionment and density of the poductive quantity. The pocedue of poduction consists of the geneating fee oxygen atom pocess fom oxygen molecule in the ai. Afte that fee oxygen atom is togethe with oxygen molecule to obtain ozone gas (O 3 ) which is bought to use in industial cued system. The occuing ozone gas pocess foms fom pocesses ionization pocess and dissociation pocess. The ionization, speading of gas, is the incement of electon avalanche leading to beaking down in insulato, which electic cuent is consideed though the bode line of insulato. The following occuence is the heat because the cuent flows in insulato, which is fom the occued beaking down. This causes the low elated enegy of ozone gas

That is electon enegy fom electicc field, having enegy less than ionization enegy but this enegy is enough to sepaate the oxygen atoms [, 3].. Block Diagam of Coona Ozonize shows the blue coona ozonize, which is constucted fom the ac high fequency switching powe supply. The ac input voltage is 4 Volt, 50 Hz supplied to ectifie cicuit in ode to poduce the dc voltage of 34 Volt. Fom the dc voltage to ac voltage, the invete contolled by Pulse Width Modulation (PWM) is used to obtain the high fequency of 0 khz. The of invete fom the pimay side steps up to highh voltage of the seconday side at kv 5 kv in ode to poduce the High Fequency High Voltage (HF-HV) into the ozone tube. Then, it geneates the ozone gas.. Co-coe cylinde: Ozone Tube s Stuctue Electic field flux is on the adius line and the suface of cylinde. Potential suface is based on Maxwell s equation of adius length: ( ). Q = fo D da co-coe cylinde s by The electic field is given by [3] Q E = () πεl Voltage (V) acoss between both cylindes is given Q V = Ed = ln πεl Q V = ln πε l V E = ( < < ln d 3 Equipvalent cicuit of electode tube and Ozone tube s stuctue [4]. The maximumm electic field stess is occued on the inside of cylinde s suface given by: V EMAX = E = (3) ln ) () The pocess of ozone gas geneating. Block diagam of coona ozonize..3 Ozone Tube Designing fo Geneate Ozone Gas The designingg layes co-coe pinciple of designingg ozone gas quantity. The ozone gas well occu in the non-unifom electic field. Thus, the designing of electode tube of -laye insulatos is chosen because insulato pemittivity is diffeent. It is appopiate with non-unifom electic field that cause the electic field stess in each laye. Theefoe, the design of -laye co-coe cylinde is composed of cylinde ozone tube is based on the - PVC, the fist insulato, is chosen because it has so a little effect to geneating ozone, whee pemittivity (ε ) = 5 - Ai is the second insulato with pemittivity (ε ) =

3 Development of Coona Ozonize Using High Voltage Contolling of Poduce Ozone Gas fo Cleaning in Cage - Cathode filled aluminum (aluminium tube) in fillament coil inside of the PVC s electic insulato is used. The eason is aluminum has a high conductivity. - Anode is a cylinde stainless steel because stainless steel does not effect to geneate ozone gas The Calculation of Ozone Tube Fom 4 shows the calculating of electode tube at l = 35 cm, =.3 cm, =.5 cm, 3 =.7 cm, ε = 5 of PVC and ε = of ai. The enegy inteval pe volume is between 5.58 kwh/m 3 and 7.73 kwh/ /m 3 because thee is % of oxygen so the enegy is.7 kwh/m kwh/m Results and Discussions 5 Full-Bidge invete cicuit fo ozone tube. 3. Test of Invete and Ozone Gas Analysis The highh fequency AC invete is contolled by IC#TL494 [4] as shown in 5. Switching devices, Powe MOSFETs#IRFP450, ae used in the invete contolled by the PWM stategy fom IC#TL494. The switching fequency is 0 khz. The enegy fom invete can tansfe though a switching tansfome to poduce highh fequency high voltage supplying the ozone tube [, 3]. 6 Invete cicuit fo ozone tube. 3.
