Abstract

A novel air-cleaner with a coil-shape photocatalysis-plasma synergistic reactor was developed. The air-cleaner showed 95% ± 1% reduction of a TVOCs concentration in tobacco smoke at “single-pass” condition. Air-purification activity of the air-cleaner was stably-maintained after the treatment of 12,000 cigarettes of tobacco smoke.

Highlights

  • We have proposed an effective method for the separation of smoking area by using “sandwich-shape” photocatalysis-plasma synergistic reactors [1]

  • In order to remove the by-products on the electrodes, air-cleaner operates for 15 min without burning cigarettes after every 200 cigarettes of tobacco smoke treatment

  • Total suspended particulates (TSPs), and total volatile organic compounds (TVOCs) concentrations were calculated after the treatments of 8, 6000 and 12,000 cigarettes of tobacco smoke at the sampling points 1 and 2 in Figure 2 as follows

Summary

Introduction

We have proposed an effective method for the separation of smoking area by using “sandwich-shape” photocatalysis-plasma synergistic reactors [1]. How to cite this paper: Ochiai, T., et al (2014) Development of a Coil-Shape Photocatalysis-Plasma Synergistic Reactor for a Practical and Long-Term Usable Air-Cleaner. Synergistic effects of photocatalysis and plasma excitation achieve the significant oxidative decomposition of gaseous compounds in tobacco smoke. Based on this result, we have fabricated the “coil-shape” PACT-TMiP reactor to reduce electrostatic capacity, pressure drop, and noise level for a long-term usability. A practical air-cleaner using the reactor was fabricated and installed in a real-scale smoking room. The air-purification ability and the long-term usability of the air-cleaner in the smoking room were confirmed
