b) Operation The specimen was placed in a desiccator (about 109 L) together with a stirring fan, and the gas to be tested was added so that the stirring fan was operated and the set gas concentration was obtained. The stirring fan was stopped, the specimen was operated, and the gas concentration in the desiccator was measured with a gas detection tube at each elapsed time. The same operation was performed without operating the specimen. A blank test was performed by performing the same operation without inserting a specimen. The test conditions are shown in Table 5.
アンモニアの試験結果を図１３に示し、硫化水素の試験結果を図１４に示す。
図１３から分かるように、アンモニア脱臭については検体を作動させることによってアンモニア除臭効果が高いことが分かり、図１４から硫化水素に対する除去性能は非常に高いことが判明した。
As can be seen from FIG. 13, it was found that ammonia deodorization has a high ammonia deodorization effect by operating the specimen, and from FIG. 14, it was found that the removal performance against hydrogen sulfide was very high.
４．タバコ粉塵除去性能評価試験
タバコ粉塵除去性能評価試験を以下の通り行ない、
サイズ幅750×奥350×高300ｍｍの密封箱中に、タバコ１本を着火し完全燃焼するまで放置後測定開始し、3分毎にタバコ粉塵濃度を測定した。試験機として、柴田科学株式会社製「デジタル粉塵計 Ｐ−５Ｈ」を用いた。タバコ粉塵除去性能の試験結果データを図１５に示す。
タバコ粉塵除去性能の試験結果データから分かる通り、自然減衰させた場合３０分間タバコ粉塵濃度はほとんど低下しなかったのに対し、本考案に係る空気清浄装置を用いた場合には１２分後には非常に低レベルまでタバコ粉塵濃度が低下することが判明した。
4). Tobacco dust removal performance evaluation test Conduct the tobacco dust removal performance evaluation test as follows,
In a sealed box with a size width of 750 x depth of 350 x height of 300 mm, a cigarette was ignited and left to stand until it completely burned, and the measurement was started every 3 minutes. As a testing machine, “Digital Dust Meter P-5H” manufactured by Shibata Kagaku Co., Ltd. was used. The test result data of tobacco dust removal performance is shown in FIG.
As can be seen from the test result data of the tobacco dust removal performance, the tobacco dust concentration hardly decreased for 30 minutes when it was naturally attenuated, but it was very much after 12 minutes when the air purifier according to the present invention was used. It was found that the tobacco dust concentration decreased to a low level.
本考案に係るコロナ放電式空気清浄装置は、浮遊細菌除去性能、花粉除去性能、脱臭効果（アンモニア及び硫化水素）、タバコ粉塵除去性能等の集塵・殺菌・消毒性能に優れているので、産業上利用可能性が大きい。 The corona discharge air purifier according to the present invention has excellent dust collection, sterilization and disinfection performance such as airborne bacteria removal performance, pollen removal performance, deodorization effect (ammonia and hydrogen sulfide), tobacco dust removal performance, etc. The top availability is great.
