Description

本発明は、汚れた衛生用品からその素材の回収方法に関し、特に、製造時に汚れた衛生用品及び使用済みの衛生用品から、その素材を再使用可能に回収する素材の回収方法に関する。また、本発明は、汚れた衛生用品から再使用可能な衛生用品用の素材を回収する衛生用品素材の回収方法に関し、特に、使用済みの衛生用品から、衛生的な衛生用品素材の回収方法に関する。 The present invention relates to a method for collecting a raw material from a dirty sanitary product, and more particularly, to a method for recovering the raw material from a sanitary product and a used sanitary product that are dirty at the time of manufacture. The present invention also relates to a method for recovering a sanitary product material for recovering a reusable sanitary product material from a dirty sanitary product, and more particularly, to a method for recovering a sanitary sanitary product material from a used sanitary product. .

紙おむつ、乳パッド、尿パッド及び生理用ナプキンなどの衛生用品は、使い捨て可能に製造されている。このような使い捨て衛生用品は、二つの吸水紙で形成された層の間に、高吸水性樹脂を含むパルプ材料で形成されている吸水層部を設け、一方の吸水紙の層の下側に不透水性のプラスチック膜を設け、他方の吸水紙の上に不織布を設けて形成されている。
この使い捨て衛生用品は、繰り返し使用するために、洗濯により清潔にとなく使用後に廃棄できるので便利であり、病院や家庭で使用されている。 Sanitary goods such as disposable diapers, milk pads, urine pads and sanitary napkins are manufactured to be disposable. Such a disposable sanitary article is provided with a water-absorbing layer portion formed of a pulp material containing a highly water-absorbent resin between the layers formed of two water-absorbing papers, and below one water-absorbing paper layer. An impermeable plastic film is provided, and a non-woven fabric is provided on the other water absorbent paper.
This disposable hygiene product is convenient because it can be used repeatedly and can be disposed of after washing without being cleaned, and is used in hospitals and homes.

このような使い捨ての衛生用品であっても、使用目的から衛生的であることが要求され、製造過程で汚れただけで廃棄されて、焼却されている。その量は、全体的には僅かであっても、全体量が多いために、焼却処理される量は無視できるものではなく問題とされている。このような衛生用品は、衛生的であることが要求されるために、再生が難しく、これまでに、再生することすら話題に上っていない。殊に、使用後の所謂使用済みおむつは、大便や小便で汚れており、その処理は、専ら、焼却によっている。使用済み紙おむつの量は膨大であり、しかも、使用済み紙おむつの廃棄処理費は、例えば、１ｋｇ当たり１００乃至１６０円であるから、大変な額に上っており、問題とされている。しかも、焼却処理には、大量の燃料及び多くの人手等を要するために問題とされている。
本発明は、このような汚れた衛生用品の再生処理に係る問題点を解決することを目的としている。 Even such disposable sanitary products are required to be hygienic for the purpose of use, and are discarded and incinerated just by being contaminated in the manufacturing process.

The material of the sanitary article is washed and sterilized by stirring in the disinfectant solution. In order to separate the sanitary product material thus treated, the disinfectant solution in which the sanitary product material is suspended is sent to a sieve having an opening of 0.1 to 1 mm, for example. By stirring treatment in the disinfectant solution, most of the water-soluble soil and solid soil adhering to the sanitary product pulverized product are dissolved or suspended in the disinfectant solution. By separating with a sieve or a filter medium, most of the water-soluble stains and solid stains adhering to the sanitary ware are contained in the sieve or the filtrate. Separated. The material of the sanitary article thus separated is washed under stirring in a further disinfectant solution. By repeatedly treating in the disinfectant solution in this way, the number of bacteria remaining in the sanitary product material is significantly reduced.

本発明において、消毒剤溶液で処理された衛生用品の素材は、最後に熱湯中に浸される。この場合も、衛生用品の素材は、撹拌下に濯ぎ洗浄され、これにより、衛生用品の素材に付着する菌は死滅し、そして菌の数は著しく減少する。このように洗浄処理された衛生用品の素材は、５乃至１０ｍｍの目開きの篩により、抗菌剤溶液の噴霧下で篩分処理される。篩上には、抗菌剤溶液により濡れたプラスチック物質を主として含む衛生用品の素材が分けられ、篩下には、篩上産物と同様に抗菌剤溶液により濡れたパルプ及び高吸水性樹脂を含む衛生用品の素材が分けられる。 In the present invention, the sanitary article material treated with the disinfectant solution is finally immersed in hot water. Again, the sanitary product material is rinsed and washed under agitation, thereby killing the bacteria attached to the sanitary product material and significantly reducing the number of bacteria. The material of the sanitary product thus cleaned is subjected to a sieving process under a spray of an antibacterial agent solution by a sieve having an opening of 5 to 10 mm. On the sieve, sanitary products that mainly contain plastic substances wetted by the antibacterial agent solution are divided. Under the sieve, sanitary products containing pulp and superabsorbent resin wetted by the antibacterial agent solution as well as the product on the sieve. The material of supplies can be divided.

篩下のパルプ及び高吸水性樹脂を含む衛生用品の素材は、高吸水性樹脂が吸水してゲル状の物質となっており、ゲル状の物質から高吸水性樹脂に含まれる水を分離除去するために、塩化カルシウム水溶液で洗浄される。
塩化カルシウム水溶液により洗浄されて脱水された篩下産物のパルプ及び高吸水性樹脂を含む衛生用品の素材は、乾燥機、例えば送風乾燥機により乾燥される。乾燥されたパルプ及び高吸水性樹脂を含む篩下産物の衛生用品の素材は、乾式分級機、例えばエア分級により、比較的低含有量の高吸水性樹脂、例えば含有量が１重量％以下の高吸水性樹脂とパルプを含む比重が小さい衛生用品の素材と、比較的高含有量の高吸水性樹脂、例えば含有量が３重量％以上の高吸水性樹脂とパルプを含む比重が大きい衛生用品の素材とに分けられて、夫々衛生用品等の原材料として使用することができる。 The material of sanitary ware including pulp under sieve and superabsorbent resin becomes a gel-like substance by absorbing the superabsorbent resin, and water contained in the superabsorbent resin is separated and removed from the gel-like substance In order to do so, it is washed with an aqueous calcium chloride solution.
The material of the sanitary product including the pulp of the under-sieving product washed with the calcium chloride aqueous solution and dehydrated and the superabsorbent resin is dried by a dryer, for example, a blow dryer. The material of the hygienic article of the sieving product containing the dried pulp and the superabsorbent resin is a relatively low content superabsorbent resin, for example, having a content of 1% by weight or less by a dry classifier, for example, air classification. A hygienic article having a low specific gravity including a superabsorbent resin and pulp, and a hygroscopic article having a relatively high content of a superabsorbent resin, for example, a hygroscopic article containing a superabsorbent resin and pulp having a content of 3% by weight or more. And can be used as raw materials for sanitary products.

本発明において、消毒剤は、汚れた衛生用品に付着する菌の殺菌に使用されるものであり、オゾン、塩素、次亜塩素酸ナトリウム、次亜塩素酸カルシウム、次亜塩素酸リチウム、二酸化塩素、臭化塩素、塩素化イソシアヌール酸、クロラミンＢ若しくはクロラミンＴがある。しかし、これらの消毒剤の他に、一般に、菌若しくは微生物の殺菌に使用される消毒剤、抗菌剤若しくは殺菌剤を使用することができる。衛生用品の菌の殺菌手段とし、消毒剤溶液を使用する場合には、消毒剤の濃度は、処理時間を短くするときは、消毒剤の濃度は高くされる。しかし３０分以上の処理時間であれば、消毒剤の使用濃度は、通常使用される程度の濃度で使用することができる。例えば、次亜塩素酸ナトリウム溶液の場合で、０．０５乃至３重量％で使用されるが、消毒の結果を調べて、その都度適宜増減して使用することができる。 In the present invention, the disinfectant is used for sterilization of bacteria adhering to dirty sanitary goods, and ozone, chlorine, sodium hypochlorite, calcium hypochlorite, lithium hypochlorite, chlorine dioxide , Chlorine bromide, chlorinated isocyanuric acid, chloramine B or chloramine T. However, in addition to these disinfectants, disinfectants, antibacterial agents, or disinfectants that are generally used for disinfecting bacteria or microorganisms can be used. In the case of using a disinfectant solution as a means for sterilizing germs of sanitary goods, the concentration of the disinfectant is increased when the treatment time is shortened. However, if the treatment time is 30 minutes or more, the disinfectant can be used at a concentration that is normally used. For example, in the case of a sodium hypochlorite solution, it is used in an amount of 0.05 to 3% by weight. However, the results of disinfection can be examined, and the amount can be appropriately increased or decreased each time.

本発明において、使用済み等の汚れた衛生用品についての粉砕は、消毒に要する時間を有効に使用するために、消毒剤の噴霧により、消毒剤溶液で濡れた衛生用品について連続的に行われるのが好ましい。しかし、本発明においては、汚れた衛生用品を消毒するために、汚れた衛生用品の粉砕物は、消毒剤溶液中で、撹拌下に消毒処理されるが、この消毒処理は、初期の消毒効果を達成するまでの間継続されるので、バッチ式で行われるのが好ましい。連続式で殺菌処理することもできるが、この場合は、初期の消毒効果を達成するまでの間、消毒処理槽内に滞留させることが必要であり、多くの設備を要することとなる。したがって、粉砕された使用済み等の汚れた衛生用品は、その量が所定量に達するまでの間、消毒剤溶液により濡れた状態で放置され、消毒が継続される。 In the present invention, sanitation of dirty sanitary products such as used is continuously performed on sanitary products wetted with a disinfectant solution by spraying the disinfectant in order to effectively use the time required for disinfection. Is preferred. However, in the present invention, in order to disinfect a sanitary sanitary product, the ground product of the sanitary sanitary product is disinfected in a disinfectant solution with stirring. Since it is continued until it achieves, it is preferable to carry out by a batch type. Although sterilization can be carried out continuously, in this case, it is necessary to stay in the disinfection tank until the initial disinfection effect is achieved, which requires a lot of equipment. Therefore, the crushed used sanitary goods such as used are left in a wet state with the disinfectant solution until the amount reaches a predetermined amount, and the disinfection is continued.

消毒剤としては、塩素ガス、液体塩素、次亜塩素酸ナトリウム、さらし粉、高度晒粉（次亜塩素酸カルシウム）、次亜塩素酸カルシウム、次亜塩素酸リチウム、有機性塩素剤、二酸化塩素又はオゾンを使用することができる。オゾンは分解速度が早く、殺菌力が大きく短時間で殺菌するが、塩素はオゾンに比して殺菌力が小さく殺菌に長時間を要する。しかし、塩素消毒剤は、オゾン消毒剤に比して殺菌力の持続性が大きいので、本発明においては、液体塩素、次亜塩素酸ナトリウム若しくは次亜塩素酸カルシウムを使用するのが好ましい。消毒剤の溶液濃度については、汚れた衛生用品の種類、汚れ状態や処理時間に応じて使用される消毒剤溶液の濃度を設定するのが好ましい。 Disinfectants include chlorine gas, liquid chlorine, sodium hypochlorite, bleaching powder, advanced bleaching powder (calcium hypochlorite), calcium hypochlorite, lithium hypochlorite, organic chlorine agent, chlorine dioxide or Ozone can be used. Ozone has a high decomposition rate and a high sterilizing power, and sterilizes in a short time. However, chlorine has a small sterilizing power compared to ozone and requires a long time for sterilization. However, since the chlorine disinfectant has a longer sterilizing power than the ozone disinfectant, it is preferable to use liquid chlorine, sodium hypochlorite or calcium hypochlorite in the present invention. Regarding the concentration of the disinfectant solution, it is preferable to set the concentration of the disinfectant solution used according to the type of soiled sanitary products, the state of soiling, and the processing time.

本発明において、例えば沸騰水又は８０℃以上の温度の熱湯が、撹拌洗浄工程で使用される。このように撹拌下に熱湯で濯ぐことにより、衛生用品の素材は熱湯により加熱され、衛生用品の素材に付着する菌を熱により滅菌することができ、再生回収された衛生用品の素材に付着する大腸菌を陰性にすることができる。一般に、使い捨て医療品の滅菌前の菌数は、例えば、生木綿で１０⁶乃至１０⁷／１ｇであり、脱脂綿で１０²乃至１０⁴／１ｇであり、ガーゼで１０²乃至１０⁴／１ｇであるが、本発明において、回収される衛生用品の素材は、少なくとも菌数が、前記例示の使い捨て医療品の滅菌前の菌数以下とすることができる。本発明において、大腸菌は死滅して形骸化し、希に僅かに残留するに過ぎないので、衛生的に問題にならない。 In the present invention, for example, boiling water or hot water having a temperature of 80 ° C. or higher is used in the stirring and washing step. By rinsing with hot water under stirring in this way, the sanitary product material is heated by the hot water, so that the bacteria adhering to the sanitary product material can be sterilized by heat, and it adheres to the regenerated and recovered sanitary product material. E. coli can be negative. In general, the number of bacteria before sterilization of disposable medical products, for example, a 10 ⁶ to 10 ^7/1 g raw cotton is absorbent cotton at 10 ² to 10 ^4/1 g, at 10 ² to 10 ^4/1 g with a gauze However, in the present invention, at least the number of bacteria in the sanitary article material to be collected can be equal to or less than the number of bacteria before sterilization of the exemplified disposable medical product. In the present invention, Escherichia coli is killed and formed into a body, and rarely remains, so it is not a sanitary problem.
