で、これらの悪臭に有効に作用する脱臭装置を得ること
は極めて困難である。However, when using various conventional deodorizing methods or deodorizing agents, it is difficult to efficiently remove the various types of odors mentioned above. The only way to reduce the odor is to prevent it from being emitted, or to adsorb part of the odor using physical or chemical adsorbents, and to reduce the odor to a level that is tolerable in daily life. Since the various types of malodors mentioned above are often combined, it is extremely difficult to obtain a deodorizing device that effectively eliminates these malodors.
また、前記した物理的、化学的吸着剤を用いた場合には
、悪臭除去後の廃材を処理する手段が難しく、処理方法
によっては二次公害を引き起こす惧れがある。Furthermore, when using the above-mentioned physical or chemical adsorbents, it is difficult to dispose of the waste material after the odor has been removed, and depending on the processing method, there is a risk of causing secondary pollution.
特に将来にわたっての生活環境問題を考慮すると、前記
脱臭剤に用いられる原料としては、物理的、化学的吸着

Ｘｌ１
以下本発明にかかる脱臭剤及びその製造方法の各実施例
を詳述する。Xl1 Examples of the deodorizing agent and the method for producing the same according to the present invention will be described in detail below.
本発明で用いられる原料は、製紙工場で用いられる各種
パルプ及び製紙工場から廃棄されるパルプスラッジであ
り、上記パルプとしてはクラフトパルプ、マニラ麻パル
プ、葦パルプ、竹パルプ。The raw materials used in the present invention are various pulps used in paper mills and pulp sludge discarded from paper mills, and the pulps include kraft pulp, Manila hemp pulp, reed pulp, and bamboo pulp.
サイザル麻パルプが利用可能である。Sisal pulp is available.
本発明ではこれらの各種パルプの中から選択して利用す
ることができる。In the present invention, it is possible to select and use these various pulps.
これらのパルプを脱臭剤として使用するに際し、該パル
プを乾留することによって多孔性を持たせたことが特徴
となっている。When these pulps are used as deodorizing agents, they are characterized by being made porous by carbonizing the pulps.
即ち、これらのパルプを高圧釜内で蒸気圧３〜６ｋｇ／
ｃｍ２、温度１２０〜１６０°Ｃで３０分〜２時間乾留
した後、乾燥して脱臭剤とする。That is, these pulps are heated in a high-pressure cooker at a steam pressure of 3 to 6 kg/
cm2, and carbonized at a temperature of 120 to 160°C for 30 minutes to 2 hours, and then dried to obtain a deodorizing agent.
上記の乾留処理とは、空気を遮断した状態でパルプを強
く加熱することによって熱分解を行わせる手段であって
、パルプ自体の多孔性が高められ、脱臭剤としての機能
が付与される。The above-mentioned carbonization treatment is a means of thermally decomposing the pulp by strongly heating it in a state where air is shut off, thereby increasing the porosity of the pulp itself and imparting a function as a deodorizing agent.
また、前記高圧釜内の蒸気圧及び温度が低く、かつ、乾
留時間が短いほどパルプ自体は強靭であり、前記蒸気圧
及び温度が高く、かつ、乾留時間が長いほど脱臭力が高
まる反面でパルプ自体の強度が低下するので、利用目的
に応じてこれらの条件を決定すれば良い。In addition, the lower the vapor pressure and temperature in the high-pressure cooker and the shorter the carbonization time, the stronger the pulp itself.The higher the vapor pressure and temperature and the longer the carbonization time, the stronger the deodorizing power, Since the strength of the material itself decreases, these conditions should be determined depending on the purpose of use.
得られた脱臭剤は厚紙状を呈しているので、用途に応じ
て適当な大きさ及び形状にカットして、例えば果物とか
野菜類を出荷する際のダンボール箱の中に入れるとか、
梱包内に封入する等の使用形態が可能である。The obtained deodorizer has a cardboard-like shape, so it can be cut into an appropriate size and shape depending on the purpose and placed in a cardboard box for shipping fruits and vegetables, for example.
It is possible to use it in a manner such as enclosing it in a package.
一方、工場廃棄物であるパルプスラッジを乾留したもの
はそのままでも使用することができるが、更に小さく粉
砕して形状を揃えるとか、ペレット状、フィルター状も
しくは適宜な形状に成形することによって脱臭剤として
の利用の道が拡大する。On the other hand, pulp sludge, which is a factory waste product, can be used as it is, but it can be used as a deodorizing agent by grinding it into smaller pieces and making it into a uniform shape, or by molding it into pellets, filters, or other suitable shapes. The ways in which it can be used will expand.
特にフィルター状に成形することによって、バキューム
カーの排気用フィルターとか、更には工場。In particular, by molding it into a filter shape, it can be used for vacuum car exhaust filters, and even factories.
し尿処理場等の排気装置等に利用することができる。It can be used as an exhaust system for human waste treatment plants, etc.
上記パルプスラッジは本来産業廃棄物として処理に苦慮
していたものであって、そのまま廃棄すると公害源とな
ってしまうため、製紙工場等において専門の処理業者に
委託している現状にあり、このような産業廃棄物を脱臭
剤として利用可能とした意義が大きいものと考えられる
。The above-mentioned pulp sludge was originally difficult to dispose of as industrial waste, and if disposed of as is, it would become a source of pollution. It is considered to be of great significance that industrial waste can be used as a deodorizing agent.
次に上記の乾留条件を種々変えた本発明にかかる脱臭剤
