    • 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.
    • 提供一种包括除臭过滤器的过滤装置和用于保持具有高除臭速度的除臭过滤器的性能的装置,其中抑制了除去的气味分子的再释放,其可以在长时间内稳定地使用而没有任何回收 操作。 除臭过滤器由用于吸附气味分子的吸附剂和用作气味分子的催化剂引起氧化反应的过渡金属螯合化合物制成。 通过吸附剂快速吸附气味与通过过渡金属螯合化合物从吸附剂分离的气味的组合具有长期性能作为过滤器的一个实例,复合除臭过滤器(10)通过包装形成 活性炭过滤器(2)具有如图所示携带过渡金属螯合物的无纺布制成的透气袋(1)。 此外,为了促进气味分子的分解,设置透气加热装置。 添加用于向复合除臭过滤器供水的供水装置,以防止在低湿度环境中降低性能。 通过除去溶解在金属酞菁配合物的碱性水溶液中的氧气,例如通过例如用惰性气体鼓泡来除去可能导致除臭性能降低的复合分子的二聚,可防止金属 酞菁在载体上载带。
