水管の清掃工事に利用される。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for cleaning the inside of a drain pipe using a biochemical treatment agent, and is used for cleaning work of drain pipes in high-rise residences and other buildings. Ru.
排水管内のクリーニング方法としては、従来、高圧水洗
浄法が一般に公知である。これは、ホースの先端に噴射

から水流を噴射させつつ管内を移動させ、噴出する水流
の衝撃力で管の内壁面に付着したスライムを除去するも
のである。As a method for cleaning the inside of a drain pipe, a high-pressure water cleaning method is generally known. This involves attaching a nozzle to the tip of the hose that rotates by the thrust of the jet, inserting this hose into a pipe, sending high-pressure water into the hose, and moving the water inside the pipe while jetting water from the nozzle. This method uses impact force to remove slime that has adhered to the inner wall surface of the tube.
また、排水管に応じた高圧水洗浄法として、複数箇所の
曲がり管部を有する排水管に挿入するために、ワイヤー

ある。In addition, as a high-pressure water cleaning method depending on the drainage pipe, a method of using a wire-braided hose and spraying at a spray pressure of 150 kg/ci or less in order to insert it into a drain pipe having multiple bends, 3b Insert the hose plated with the same wire into the drain pipe with the following pipe diameter, 10k
There is also a method of injecting at a low injection pressure of g/cnf or less.
中高層集合住宅の台所系排水管、ビルの営業用厨房系排
水管などでは、排水中に脂肪分が多量に含まれている。Kitchen drain pipes in mid-to-high-rise apartment complexes and commercial kitchen drain pipes in buildings contain large amounts of fat in the waste water.
この脂肪分は粘性が高く、しかも常温で固形化するから
管の内壁面に付着し易く、これが蓄積すると管央部にせ
り出して水流を阻害し、排水管が詰まる主要な原因とな
っている。このような排水管の通水不良の状態は縦管と
横管では異なっており、縦管では、第２図に示すように

管（１ａ）の内壁面に付着し管央部に盛り上がって通水
面積を縮小させているか、横管ては、第３図に示すよう
に、スライム（ｍ）は横管（２ａ）の両側力ら上部の内
壁面に付着して通水面積を減少させている。This fat has a high viscosity and solidifies at room temperature, so it easily adheres to the inner wall of the pipe, and when it accumulates, it protrudes toward the center of the pipe, obstructing water flow and becoming a major cause of clogged drain pipes. The condition of poor water flow in drainage pipes is different between vertical pipes and horizontal pipes. In vertical pipes, as shown in Figure 2, slime (m) whose main component is solidified fat is The slime (m) adheres to the inner wall surface of the pipe (1a) and bulges in the center of the pipe, reducing the water flow area. It adheres to the upper inner wall surface and reduces the water flow area.
したがって、排水管のクリーニングでは、管壁に付着し
ている固形化した脂肪を完全に除去することが重要であ
るが、前述した従来の方法には次のような問題点があっ
た。Therefore, when cleaning drain pipes, it is important to completely remove the solidified fat adhering to the pipe walls, but the conventional methods described above have the following problems.
（イ）管央部に盛り上がったスライムの大部分は噴出す

きないから、クリーニング後に固形脂肪が再び付着しや
すい。(b) Most of the slime that has risen in the center of the tube is removed by the impact force of the ejected water flow, but even in this case, the position of the nozzle is uneven within the tube, resulting in uneven removal and making the inner surface of the tube uniform. In addition, the slime layer that adheres to the tube wall in the form of a film cannot be removed uniformly, so solid fat tends to re-adhere after cleaning.
（ロ）従来の方法では、通常、噴射圧力を５０〜４００

が切れるというトラブルが発生する。(b) In the conventional method, the injection pressure is usually set at 50 to 400.
kg/ci and the amount of water jetted is 30 to 100Q/cE, but if the jetting pressure and amount of water are increased to increase the cleaning effect, the pipes will be damaged and water will leak from the connections, etc. Problems occur when the air pressure inside the pipe changes and the water seals on each device break.

理能力を超えた過負荷状態を惹起する。(c) The slime separated by the impact force of the water jet flows directly into the sewage treatment plant through rivers or sewers, unless a combined septic tank is installed. This slime, especially the amount of solid fat, is 10g of solidified fat that is excreted per day per household (standard for a family of 4).
The amount of non-cleaning days multiplied by the total number of households cleaned is extremely large, causing pollution such as water pollution in the rivers that flow into it, and the sewage treatment load at sewage treatment plants increases all at once, resulting in overloads exceeding the processing capacity. cause a condition.

ライムが除去されたのち、管壁に付着している膜状のス
ライム層の表面にも処理水流が飛散して付着するので、
このスライム層も同様に分解される。With this injection, the slime in the center of the pipe is first crushed into small pieces by the impact force of the treated water flow, and the crushed small pieces are instantly repelled in a turbulent direction by the treated water flow that hits the pipe wall and scatters. The mixture is in an agitated state, and a stream of treated water is applied to almost the entire surface of each small piece, and solid fat is broken down by the enzyme lipase and eluted and flows down. In addition, after the slime in the center of the pipe is removed, the treated water flow scatters and adheres to the surface of the film-like slime layer adhering to the pipe wall.
This slime layer is similarly decomposed.
したがって、ノズルからの噴射圧力はスライムを破砕し
撹拌させることができる程度であればよく、前記膜状の
スライム層を剥離させるほどの高い圧力にする必要はな

に付着するから、スライムが除去されずに残ることはな
く管壁は均一にクリーニングされる。Therefore, the jetting pressure from the nozzle only needs to be at a level that can crush and stir the slime, and there is no need to set the pressure so high as to peel off the film-like slime layer. In this case, even if the jet nozzle is uneven in the pipe, the stream of treated water sprayed violently scatters inside the pipe and adheres to almost the entire inner surface, so the slime does not remain unremoved and the pipe wall is uniform. Cleaned.

Braid the hose with a guiding wire and insert it into the pipe. Even in this case, since the injection pressure may be as low as described above, the cleaning action described above can be performed without causing any damage to the pipe connections or the like. In particular, in such complex pipes, the treated water flow that is injected scatters inside the pipe, forms a mist or jet, and adheres to the entire inner surface of the pipe, decomposing solid fat, which cannot be removed using conventional methods. Even difficult parts of the pipe wall can be reliably cleaned.

方法によればこの点が解決される。As a result, the solid fat is decomposed by the enzyme lipase and eluted in the same manner as described above. At this time, tartaric acid and potassium hydrogen tartrate use their foaming power to stir and disperse the solid fat in the slime and further expand the decomposition action area of the enzyme lipase.
The degrading action of lipase is further improved. In drain pipes with such a high degree of blockage, if slime is removed with a large amount of water jetted all at once, there is a risk that the slime will peel off at once and clog other parts of the pipe or branch pipes. This method solves this problem.

Inject onto the pipe wall at an injection pressure of 80 kg/ffl. In the present invention, as will be described later, the injection pressure from the nozzle (5) is sufficient to crush the slime inside the pipe, and there is no need to peel off and wash away the film-like slime layer adhering to the pipe wall. , a pressure as low as this is sufficient.

なく、管壁は均一にクリーニングされる。FIG. 4 is an explanatory diagram of the action inside the pipe during injection. First, the slime (m) in the center of the pipe is crushed into small pieces by the force of the treated water flow, and the crushed pieces are instantly repelled in a turbulent direction by the treated water flow that hits the pipe wall and scatters. The processed water flow adheres to almost the entire surface of each small piece, and the solid fat is broken down by the enzyme lipase and falls off. In addition, after the slime protruding from the center of the tube is removed, the treated water flow also scatters and adheres to the surface of the film-like slime layer (m') attached to the tube wall, so this slime layer also It is decomposed into For this reason, the injection pressure from the nozzle (5) only needs to be at a level that can crush and stir the slime, and there is no need to set it to a pressure so high as to cause the film-like slime layer to peel off. In this case, even if the jet nozzle (5) is uneven in the pipe, the stream of treated water sprayed violently scatters inside the pipe and adheres to almost the entire inner surface, so no slime remains unremoved. , the pipe wall is evenly cleaned.

いる。次にその試験例を示す。In the above, the upper limit of the pH value of sodium hydrogen carbonate is 8.
．． 4, the pH of the aqueous solution of the treatment agent can be maintained at the upper limit of 9 just by adding it, but it also has the effect of dispersing and swelling the solid fat in the slime, thereby increasing the decomposition activity of the enzyme lipase. The area of action is expanded. Next, a test example will be shown.
試験例１
この試験例は、水と炭酸水素ナトリウム溶液との固形油
脂に対する分散作用をみたもので、試験材には固形５号
ラードを用いた。双方とも水５０（資）を２５℃に保ち

，１にして５号ラードを浸漬しその状態をみた。Test Example 1 This test example examined the dispersion effect of water and sodium bicarbonate solution on solid fats and oils, and solid No. 5 lard was used as the test material. In both cases, water 50% (stock) was kept at 25℃, and 7.5g of sodium hydrogen carbonate was added to one side, and the pH was adjusted to 8.
, No. 5 lard was immersed in the water at a temperature of 1 and the condition was observed.
試験例２
本試験例では、水と炭酸水素ナトリウム溶液に脂肪分解

いた。Test Example 2 In this test example, a lipolytic enzyme lipase was added to water and a sodium bicarbonate solution, and the amount of lipase was measured from the substantially uniform dispersion state of solid No. 5 lard after 10 minutes. 50cc of water was kept at 25°C in both cases, and 0.5g of sodium hydrogen carbonate was added to one, and the pH was adjusted to 8.0.
Then No. 5 lard was soaked. The lipase added to water had a maximum active point of pH 7 and was activated by water.
上記の試験例から、炭酸水素ナトリウムによって固形油

積が増大することがわかる。また、リパーゼが浸潤して

れ、同一の分解効果をあげるのに必要な量は水の１０分
の１でよいことがわかる。From the above test examples, it can be seen that solid fats and oils are dispersed into fine blocks or granules by sodium hydrogen carbonate, and their surface area increases. It is also understood that fat is reliably decomposed because the area where lipase infiltrates and acts becomes wider, and that only one-tenth of the amount of water is required to achieve the same decomposition effect.

を持続させるように作用する。In addition, since the treated water stream is slightly alkaline with an upper limit of pH 9, no pollution problem will occur even if the stream of slime after decomposition flows into a river or the like. In addition, N-acylamino acids act to enhance the storage stability of the processing agent and to maintain enzyme activity after dissolution in water.

ニングできる。In addition, as shown in Fig. 6, the hose (4) is guided to multiple bent pipe piping parts such as elbows and teeth, and bent pipes such as the Sovent (trade name) ventilation joint (7) shown in Fig. 5. Place the wire (8) on the plate and insert it into the tube. Even in this case, since the injection pressure may be as low as described above, no damage is caused to the connecting portions of the pipes, and the cleaning action described above is performed. In particular, in complex pipes like this, the injected treated water flow scatters inside the pipe and forms a mist or mist that adheres to the entire inner surface of the pipe, so it is difficult to remove even parts of the pipe wall that are difficult to remove using conventional methods. Can be cleaned reliably.

Insert it, operate the pump (3), and draw it back to the insertion port while jetting a stream of treated water from the nozzle (5). In addition,
After cleaning the vertical drainage pipe (1), next clean the horizontal drainage pipe (

れる。This is done in the same way as above. Inside this horizontal pipe (2), the nozzle (5) moves toward the bottom of the pipe, but as mentioned above, the treated water flow scatters inside the pipe and becomes a mist or mist, including the upper part. Since it adheres to its entire inner surface, the tube wall is uniformly cleaned by the decomposition action of the enzyme lipase.

Pour into a drain pipe with a stagnant water volume of 30 ff (amount of water that remains in the pipe without being immediately drained). The second pouring may be performed before inserting the wire into the pipe, at the same time as the wire is inserted and the slime is crushed, or after the slime is crushed.

きる。As a result, solid fat, which is the main component of the slime in the tube, is decomposed by the lipase enzyme and eluted in the same manner as described above. At this time, tartaric acid and potassium hydrogen tartrate stir the slime with their foaming power to swell the solid fat and expand the decomposition action area of the enzyme lipase. In addition to the above-mentioned foaming agents, citric acid, succinic acid, malic acid, uric acid, fumaric acid, sodium fumarate, etc. can be used as the foaming agent.

することができる。In drain pipes with a high degree of blockage, if slime is removed with a large amount of water jetted all at once, there is a risk that the slime in the center of the pipe will peel off at once and clog other parts of the pipe or branch pipes. However, according to the method of this example, about 5 to 1
Since the slime is decomposed and eluted in 0 minutes, the slime can be removed without clogging other parts of the pipe or branch pipes.

の封水切れなどの管損傷を来たすことがない。(b) The injection pressure from the nozzle can be adjusted by crushing the slime in the center of the tube, stirring it momentarily, and making the treated water flow adhere to almost the entire surface of each small piece. Since no pressure is required to separate the water, a lower injection pressure is required than in conventional high-pressure water cleaning methods, and pipe damage such as water leakage at connections or broken water seals in various instruments does not occur.

一な状態で確実にクリーニングできる。(b) The surface area of the solid fat in each crushed small piece is increased by the dispersion and swelling action of sodium bicarbonate, and lipase acts on this to effectively decompose it, and the The treated water flow scatters and adheres not only to the slime but also to the film-like slime layer adhering to the tube wall, which is similarly decomposed and can be completely cleaned without leaving any solid fat on the tube wall. In particular, the flow of treated water scatters and adheres to parts of complicated drainage pipes such as curved pipes that are difficult to remove using conventional methods, making it possible to reliably clean the inside of the pipe in a uniform state.
