脱臭処理が可能な吸着分解脱臭剤に関するものである。Detailed Description of the Invention [Industrial Application Field] The present invention adsorbs and removes malodorous gases or harmful gases and performs heat regeneration to continuously desorb and release the malodorous gases or harmful gases, which can be catalytically decomposed as they are while being regenerated. The present invention relates to an adsorption/decomposition deodorizing agent capable of deodorizing treatment.

触媒を用いて接触分解する方法も広く行なわれている。Conventionally, adsorbents such as activated carbon, zeolite, silica gel, and alumina have been used to adsorb and remove malodorous or harmful gases. Furthermore, methods of catalytically decomposing malodorous gases or harmful gases using oxidative decomposition catalysts are also widely practiced.

ゲル、ゼオライトなどが用いられると記載されている。The adsorbent and oxidation catalyst are sufficiently mixed to form a single layer, or the adsorbent layer and the oxidation catalyst layer are arranged alternately to form an apparent upper layer, or the adsorbent and oxidation catalyst metal is attached to the surface of the adsorbent. A harmful gas treatment device is disclosed that is characterized by being filled with a material that has both the functions of a catalyst to form a single layer, and it is stated that activated carbon, activated alumina, silica gel, zeolite, etc. are used as the adsorbent. has been done.

用いても吸着能はかならずしも満足のいくものではなく
、また再生による吸着能の賦活化も十分でないという欠
点を有していた。However, using activated carbon as an adsorbent is dangerous because it may catch fire if exposed to high temperatures during regeneration. Further, even when adsorbents with high refractory properties such as alumina and zeolite are used, the adsorption capacity is not always satisfactory, and the adsorption capacity cannot be activated sufficiently by regeneration.

る。In addition, adsorption-decomposition deodorizing agents in which an oxidation catalyst is supported on sepiolite can oxidize and decompose malodorous or harmful gases that are desorbed during regeneration at a lower temperature, and the deodorization performance is less likely to deteriorate due to heating during regeneration for a long period of time. There is a demand for products with excellent durability that can withstand repeated recycling and use.
さらに、悪臭ガスの中に含まれる硫黄は強い触媒毒とし
ての作用を持っているので、この硫黄による被毒に耐え
うるものが要請されている。Furthermore, since sulfur contained in malodorous gas acts as a strong catalyst poison, there is a need for something that can withstand poisoning by this sulfur.

脱臭剤を見出した。[Means and effects for solving the problem] As a result of intensive research in line with the above objectives, the present inventors have found that malodorous gases or harmful gases are adsorbed and removed at normal processing temperatures, and By heating, the adsorbed malodorous gas or harmful gas can be desorbed, and at the same time, the desorbed and released malodorous gas or harmful gas can be oxidized and decomposed more efficiently at a lower temperature, and heating during regeneration can prevent deterioration of oxidation decomposition ability. We have discovered an adsorption-decomposition deodorizer that has little resistance to sulfur poisoning.

The gas is adsorbed and removed, and the adsorbed malodorous or harmful gas is desorbed by heating regularly or irregularly, regenerating the adsorption capacity, and the desorbed malodorous or harmful gas is oxidized and decomposed using a supported oxidation catalyst. It can purify gas, eliminates the need for continuous heating, which was essential with conventional oxidation catalysts, and enables long-term continuous use, which was not possible with simple adsorption deodorizers, and also at lower temperatures. It can be oxidized and decomposed more efficiently, and has excellent heat resistance so that its deodorizing performance does not deteriorate even after repeated heating and regeneration. have characteristics.

冷蔵庫内の脱臭が行われる。Refrigerators with forced air circulation reduce cooling performance if frost forms on the cooler, so a defrost heater is used to automatically defrost the refrigerator. When the adsorption decomposition deodorizer of the present invention is installed near the defrosting heater in the cooling air circulation path, the air inside the refrigerator is circulated through the circulation path by the fan during cooling operation of the refrigerator. The malodorous gas generated from the stored food is adsorbed and removed by the adsorption/decomposition deodorizer, thereby deodorizing the inside of the refrigerator.

己破壊しやすく、原型をとどめることが困難である。Furthermore, since the adsorption capacity of the adsorption decomposition deodorizer can be regenerated and the adsorbed malodorous gas can be oxidized and decomposed by using the heat of the defrosting heater, the adsorption decomposition deodorizer of the present invention can be used for refrigerator deodorization, etc. It can be applied very effectively. When used to deodorize refrigerators, the adsorption-decomposition deodorizer is repeatedly frozen and heated under conditions in which a large amount of moisture adheres to or is adsorbed, so plate-shaped carriers other than those made of sepiolite tend to self-destruct and lose their original shape. It is difficult to stop.
