    • To provide a filter apparatus including a deodorizing filter and means for maintaining the performance of the deodorizing filter having a high deodorizing speed, in which re-release of removed odor molecules is suppressed, which can stably used for an extended period of time without any recovery operation. A deodorizing filter is made of an adsorbent for adsorbing odor molecules and a transition metal chelate compound which serves as a catalyst for the odor molecules for causing an oxidation reaction. Combination of fast odor adsorption by means of the adsorbent with decomposition the odor which has been separated from the adsorbent with the transition metal chelate compound maintains long-term performance As an example of the filter, a composite deodorizing filter (10) is formed by wrapping an activated carbon filter (2) with an air-permeable bag (1) made of unwoven fabric on which the transition metal chelate compound is carried as shown in the drawings. Further, air-permeable heating means is disposed for the purpose of promoting the decomposition of odor molecules. Water supply means for supplying water to the composite deodorizing filter is added to prevent the lowering of the performance in a low humidity environment. By removing oxygen which is dissolved in the alkaline aqueous solution in which metal phthalocyanine complex is dissolved by means of, for example bubbling with an inert gas, dimerization of complex molecules which may otherwise cause the deodorizing performance to be lowered is prevented from occurring and metal phthalocyanine is carried on a filter carrier.
    • 本发明提供一种过滤装置,该过滤装置具备除臭过滤器和维持除臭速度高的除臭过滤器的性能的装置,该除臭过滤器能够抑制除去臭味分子的再释放,能够长时间稳定地使用而无需回收 操作。 除臭过滤器由用于吸附臭味分子的吸附剂和用作引起氧化反应的气味分子的催化剂的过渡金属螯合化合物制成。 利用吸附剂快速吸附气味与分解吸附剂与过渡金属螯合化合物分离的气味的组合保持长期性能作为过滤器的一个例子,组合式除臭过滤器(10)通过包裹 如附图所示,带有由无纺织物制成的透气袋(1)的活性炭过滤器(2),其上承载有过渡金属螯合物。 此外,为促进气味分子的分解而设置透气性加热装置。 为了防止低湿度环境下的性能下降,添加用于向组合式除臭过滤器供水的供水装置。 通过例如利用惰性气体的鼓泡除去溶解在其中溶解有金属酞菁配合物的碱性水溶液中的氧,防止了可能导致除臭性能降低的复合分子的二聚化,并且金属 酞菁负载在过滤器载体上。
