This master thesis analyzes investigation data of nanoparticles collection with electrostatic precipitator. The intensive research shows that deposition of nanoparticles in human’s body causes asthma, chronic pulmonary disease exacerbations, increases higher bronchitis sickness rate. Facilities for detention of aerosol particles have already been created, but the indoor air cleaning needs more effective small dimensions cleaning technology. Small – sized electrostatic precipitator’s prototype for home ventilation system was created in laboratory. During the study of electrostatic precipitator, the parameters such as electrification and deposition voltage zones, number of sections of collector, air flow generated by the particle source have been consistently changing. The study found that the electrostatic precipitator’s best effectiveness is achieved with two collector sections when section’s precipitation voltage is 8 kV and a electrification’s section voltage – 15 kV. The optimal supply air flow rate is 30 m3/h. In the economical part, electrostatic precipitator’s gas purification cost is calculated. The purified gas 1000 m3 cost is 0,13 EUR. In order to reduce ozone’s concentrations, it is necessary to fit an additional manganese dioxide catalyst unit at the end of the separator, because it helps to divide ozone. |
