Embodiment approach 1

[0042] Fig. 1A is an external schematic diagram showing a deodorant body in the first embodiment of the present invention, and Fig. 1B is an enlarged schematic diagram of the surface of the deodorant body. The deodorant body 1 is a honeycomb structure formed by alternately laminating flat plates and corrugated plates made of organic fibers such as polyester fibers represented by polyethylene terephthalate or cellulose fibers as the carrier 3. Ventilation in ventilation direction 2 with low ventilation resistance.

[0043] The carrier 3 carries an adsorbent 4 having a physical adsorption function (hereinafter referred to as a physical adsorbent 4 in this embodiment) and an oxide 5 having a catalytic function (hereinafter referred to as a catalyst oxide in this embodiment) on the surface. 5). The physical adsorbent 4 or the catalyst oxide 5 is bonded and supported on the carrier 3 by anchoring action, physical bonding or chemical bonding. At this time, it is preferable to add ...

Abstract

A deodorizer includes an adsorbent (4) having a physical adsorption capability, an oxide (5) containing cobalt and having a catalytic activity, and a carrier (3) for carrying the adsorbent (4) and the oxide (5). The oxide (5) transforms aldehydes to carboxylic acids, and the adsorbent (4) removes the carboxylic acids by adsorption.

Description

technical field [0001] The present invention relates to a deodorizing body, a deodorizing device and an air conditioner using the deodorizing body, which can absorb and remove odorous substances contained in the gas in living spaces such as rooms and cars, and can especially use the main components of cigarettes, which are also Acetaldehyde, which is a kind of VOC, which is highly harmful, is converted into acetic acid which is less harmful, and is adsorbed and removed. Background technique [0002] Conventionally, platinum-based thermocatalysts that decompose odorous substances and the like into water, carbon dioxide and the like by operating a catalyst using platinum metal at a high temperature (200° C. or higher) have been widely known. [0003] In addition, a catalyst for deodorization using a transition metal composite oxide mainly based on manganese has been proposed, and a composite oxide of manganese and cobalt is used to decompose 80% of acetaldehyde at 50° C. (for ...
