Zusammenfassung:PROBLEM TO BE SOLVED: To solve the problem that a conventional air cleaner has difficulties in safely and efficiently collecting radioactive substances in air and PM2.5 in spite of ability to clean air by utilizing the action of corona discharge and in carrying out maintenance easily.SOLUTION: A cassetted air cleaner is configured by oppositely arranging a plurality of tape-like positive electrodes 2, wound around a feed drum 3 and a take-up drum 4 to be cassetted, nearly in parallel with a stream of ion wind, and by arranging a brush-like negative electrode 1 and a tabular negative electrode 9 between these oppositely provided tape-like positive electrodes 2, discharges these three electrodes 1, 9 and 2 by impressing high voltage among them to generate negative ion wind with ambient air circulated through these electrodes to make powder dust contained in air stick to the tape-like positive electrodes 2, and detects the amount of this sticking powder dust to control the tape-like positive electrodes 2 wound around the take-up drum 3 by ultralow speed travel or intermittent travel to wind the same around the take-up drum 4.SELECTED DRAWING: Figure 1 【課題】従来の空気清浄機は、コロナ放電の働きを利用して空気を清浄にすることはできるが、空気中の放射性物質やPM2.5を安全・効率よく収集することが困難であり、さらに簡易にメンテナンスが行えない。【解決手段】送りドラム3と巻き取りドラム4に巻回してカセット化したテープ状プラス電極2を、対向してイオン風の流れに対して略平行に複数配設し、この対向して設けられたテープ状プラス電極2間にブラシ状マイナス電極1と、板状マイナス電極9を配設し、この3つの電極1、9と2間に高電圧を印加することで放電して、マイナスイオン風を発生させ、周囲の空気がこの電極間を通って循環し、空気中に含まれる微細な粉塵をテープ状プラス電極2に付着させ、この付着した粉塵量を検出して送りドラム3に巻回されているテープ状プラス電極2を巻き取りドラム4に巻き取るように超低速走行や間欠走行による制御を行うカセット化した空気清浄機。【選択図】図1
