Description

  The present invention relates to a water vapor pressure lowering agent, a method for preventing the breakage of drainage traps using a water vapor pressure lowering agent, a water antifreezing agent, a method for preventing the drainage trap breakage using water antifreezing agents, and a plant freeze prevention. It relates to the agent.

  2. Description of the Related Art Conventionally, drain pipes such as washstands and sinks have been provided with drain traps for collecting water in order to prevent bad odors from entering the room from the sewage side and organisms such as pests from entering the room. However, if you do not use a wash basin, sink, etc. for a long time due to reasons such as the absence of a house or the absence of a condominium borrower, the sealed water will evaporate (drought) and bad odor will enter the room from the sewage side. There is a risk that organisms such as pests may enter the room. Therefore, in order to prevent evaporation of the sealed water, oil was poured into the sealed water to cover the water surface (for example, see Non-Patent Document 1).

  However, the oil has a specific gravity that is lighter than that of water, and has a drawback in that it is difficult to move the sealed water from the drain outlet side to the sewage side when thrown. Furthermore, there is a problem that the water in the drain trap freezes in cold regions, and conventionally, ethylene glycol has been used for cold regions.

Trapkeeper EC-101 website address http://www.lifestyle-service.net/torapkeep/torapkeep.htm

When the oil is added, it is difficult to move the sealed water from the drain port side to the sewage side. In addition, the ethylene glycol is a poisonous deleterious substance with a lethal dose, and has a high risk if it flows into the natural world. In addition, the central heating refrigerant (water) has a problem that water freezes in cold regions.
Therefore, an object of the present invention is to provide a water vapor pressure reducing agent that is safe and can be easily mixed with sealed water and can be used even in cold regions.

  A first characteristic configuration of the water vapor pressure reducing agent of the present invention includes urea, a surfactant, purified glycerol, and water or alkali-reduced water, and the purified glycerol contains ethanol, fat and water, and water. Waste glycerol having carbides is purified by distillation.

According to the first characteristic configuration of the present invention, both urea and purified glycerol are well dissolved in water, and the freezing point of water can be lowered and the boiling point can be raised. Moreover, the boiling point of water can be further increased by their synergistic effect, and the vapor pressure can be decreased.
In addition, the surfactant reduces the surface tension, and for example, the capillary phenomenon due to dirt and dust adhering to the inner peripheral wall of the drainage pipe is less likely to occur in the drainage section. The amount of evaporation of the sealed water can be suppressed.
In addition, when water is not present mainly for urea and purified glycerol to reduce the vapor pressure, urea is a solid crystal at room temperature, and purified glycerol is sealed in sealed water due to its high viscosity. It is difficult to throw in, and even if it is thrown in, it is not easy to mix with the sealed water, and therefore it is difficult to lower the vapor pressure of the sealed water. On the other hand, it becomes easy to mix with sealing water by having water or alkali reduction water, and the fall of the vapor pressure of sealing water can be performed rapidly.
In addition, refined glycerol is a product obtained by distilling and purifying waste glycerol containing ethanol, fats and oils, water, and carbides. Therefore, waste glycerol, which is generally difficult to treat as special industrial waste, can be used at low cost and discarded. Contributes to the reduction and effective use of goods.

  According to the third characteristic configuration of the present invention, when the water or alkaline reduced water is less than 20% by weight, the viscosity of the vapor pressure reducing agent becomes high and it becomes difficult to put it into the sealed water, and when it exceeds 80% by weight. The ratio of urea and purified glycerol decreases, and the effect of lowering the vapor pressure decreases.

  The 4th characteristic structure of this invention exists in the place which sets the whole pH to 9.0-10.0.

According to the 4th characteristic structure of this invention, if the whole pH is less than 9.0, microorganisms will grow easily in the waste_water | drain in the sealed water to introduce, and if it exceeds 10.0, the microbial film in piping will be killed.

Moreover, the boiling point of water can be further increased by their synergistic effect, and the vapor pressure can be decreased.
In addition, the surfactant reduces the surface tension, and for example, the capillary phenomenon due to dirt and dust adhering to the inner peripheral wall of the drainage pipe is less likely to occur in the drainage section. The amount of evaporation of the sealed water can be suppressed.
In addition, when water is not present mainly for urea and purified glycerol to reduce the vapor pressure, urea is a solid crystal at room temperature, and purified glycerol is poured into sealed water because of its high viscosity. It is difficult to mix with the sealed water even if it is added, and therefore it is difficult to lower the vapor pressure of the sealed water. On the other hand, it becomes easy to mix with sealing water by having water or alkali reduction water, and the fall of the vapor pressure of sealing water can be performed rapidly.
In addition, refined glycerol is a product obtained by distilling and purifying waste glycerol containing ethanol, fats and oils, water, and carbides. Therefore, waste glycerol, which is generally difficult to treat as special industrial waste, can be used at low cost and discarded. Contributes to the reduction and effective use of goods.
Therefore, by having urea, surfactant, purified glycerol, and water or alkaline reduced water, the vapor pressure is lowered and the sealing function in the drain trap is maintained for a long period of time. In addition, the freezing point depression can be demonstrated and the effect of preventing the freezing of the sealed water can be expected, and the drainage trap can be prevented from being damaged regardless of the temperature change.

Is difficult to expect.
When the surfactant is less than 0.1% by weight or more than 5% by weight, it is difficult to exert the effect as the surfactant.
If the purified glycerol is less than the lower limit, the vapor pressure does not decrease sufficiently, and if it exceeds the upper limit, the viscosity becomes high, making it difficult to charge, and the ratio of the remaining water or alkaline reduced water decreases, making handling difficult. Become.
Therefore, the above-mentioned urea is 5 to 20% by weight, the surfactant is 0.1 to 5% by weight, the purified glycerol is 10 to 80% by weight, and the remainder is mainly water or alkali reduced water. Breakage due to freezing in the drain trap can be prevented while maintaining the sealing function by exerting a pressure lowering effect.

  The 10th characteristic structure of this invention exists in the place which has 20 to 80% of the said water or alkali reduction water.

  According to the 10th characteristic structure of this invention, when water or alkali reduced water is less than 20 weight%, when the viscosity of a vapor pressure reducing agent becomes high and it becomes difficult to inject into sealing water, when it exceeds 80 weight% The proportion of urea and purified glycerol decreases, and not only the vapor pressure decreases but also the freezing point lowering effect decreases.

  The eleventh characteristic configuration of the present invention is that the overall pH is 9.0 to 10.0.

According to the fifteenth characteristic configuration of the present invention, urea and purified glycerol can be dissolved well in water to lower the freezing point of water, respectively, and furthermore, the freezing point of water in the plant can be lowered by their synergistic effect. Moreover, purified glycerol is obtained by distilling and purifying waste glycerol, and waste glycerol, which is generally difficult to treat as special industrial waste, can be used at low cost, contributing to reduction and effective use of waste.
In addition, the fats and carbides contained in the purified glycerol increase the hydrophilicity by the surfactant and reduce the surface tension, thereby improving the wettability to the plant and making it easier to stay without spilling, preventing freezing The effect can be sustained.

  According to the present invention, when it is put into the drain trap, it is easily mixed with the whole sealed water. Furthermore, it does not easily evaporate and ensures a sealing effect over a long period of time. In particular, in a cold region, the vapor pressure is sufficiently reduced so that it does not freeze and the safety is high.

1 and 2, when the water vapor pressure reducing agent 5 according to the present invention is introduced from the upper opening 3 of the drain pipe 2 having the S-shaped drain trap T, the inside of the S-shaped drain trap T Mix with sealed water W.
As shown in FIG. 1, when the drainage trap T is introduced from the opening side, it is naturally mixed with the whole sealing water W to become a mixed sealing liquid 10 as shown in FIG.
The water vapor pressure reducing agent 5 according to the present invention contains urea, a surfactant, purified glycerol, and water or alkali-reduced water. Specifically, the urea has a surface activity of 5 to 20% by weight. It is composed of 0.1 to 5% by weight of the agent, 10 to 80% by weight of purified glycerol, and the remainder mainly composed of water or alkali-reduced water.

The purified glycerol is desirably obtained by distillation purification (generation) of waste glycerol containing ethanol, fats and oils, and carbides.
Waste glycerol is a vegetable-derived edible waste oil (iodine number is 120 or higher and has a high boiling point. For example, in the case of soybean oil, the iodine value is 124 to 139), and biodiesel fuel (abbreviation: BDF) is purified. It is a by-product (black unnecessary product), and the melting point of pure glycerin is -8 ° C to -7 ° C, which is lower than that of 17.8 ° C. It is something that is in trouble. In other words, unnecessary waste can be reused (recycled) by making use of the above characteristics, thereby contributing to the reduction and effective use of waste.

  The purified glycerol is 10 to 80% by weight, preferably 50 to 75% by weight. If it is less than the lower limit value (the vapor pressure is not sufficiently reduced), the water evaporates quickly from the mixed sealing liquid 10 shown in FIG. 2 and is easily frozen, making it unusable for practical use in cold regions. If the upper limit is exceeded, there is a risk of ignition (combustion). In addition, if the upper limit is exceeded, the viscosity may increase, and may settle and accumulate in the lower part of the drain trap T. Further, purified glycerol lowers the freezing point and raises the boiling point.

Urea has a weak sterilizing power and has a boiling point of 135 ° C. and a component ratio of 5 to 20% by weight, preferably 10 to 15% by weight. If it is less than the lower limit value, the vapor pressure from the mixed sealing liquid 10 does not drop sufficiently, and the water evaporates quickly and is likely to freeze, making it unusable for practical use in cold regions. If the upper limit is exceeded, purified glycerol and urea react to form a coagulum. That is, since waste glycerol contains oil and fat and is difficult to completely remove even by distillation purification, a small amount of fat and oil contained in the purified glycerol reacts with urea to solidify and become cloudy.
Moreover, the freezing point can be lowered (hard to freeze) by urea and purified glycerol, and an effect as an antifreezing agent is obtained.

The surfactant is 0.1 to 5% by weight, preferably 0.1% to less than 5% by weight, and more preferably 2 to 4% by weight. The surface tension is lowered by the surfactant. By reducing the surface tension (compared to water), it becomes difficult for capillary action due to dirt and dust adhering to the inner peripheral wall of the drain pipe to be suppressed, so that the suction of the mixed seal water 10 is suppressed and the amount of evaporation can be suppressed. . If the numerical value range is exceeded, foaming may occur when the vapor pressure reducing agent 5 is added, resulting in insufficient mixing, and if it is less than the lower limit value, the effect of suppressing the capillary phenomenon may be difficult to obtain.
The surfactant is preferably, for example, an alkaline detergent (manufactured by “Smart Wash” Co., Ltd. Smart).

  Further, when the proportion of water or alkali reduced water (% by weight) increases, the vapor pressure increases and the freezing point (freezing point) also increases. Originally, the freezing point of purified glycerol is about −120 ° C., but water or electrolytic alkaline ionized water is added thereto, so that the freezing point is increased, and the freezing point is set to −40 ° C. to −25 ° C. The temperature is preferably -40 ° C to -35 ° C, more preferably -40 ° C to -38 ° C.

Further, when the remainder is mainly water (pure water or tap water), there are advantages that the cost of manufacturing and equipment is lower than that of alkali reduced water, and the vapor pressure reducing agent 5 can be manufactured at low cost.
When alkaline reduced water is used, deterioration (oxidation) of the drain pipe 2 can be suppressed as compared to the case of water.
The “main” of “mainly water (or alkali-reduced water)” means that the remaining liquid, excluding purified glycerol, urea, and surfactant, is 100% by weight. 100% by weight means water (or alkali-reduced water). For example, when the remaining liquid is all water (or alkali-reduced water), pigments, fragrances, disinfectants and the like are contained in an amount of 0.1 to 5% by weight in addition to water (or alkali-reduced water). If you mean.
The alkaline reduced water is also called electrolytic alkaline ionized water or electrolytic alkaline reduced water.

Further, it is necessary to have 20% to 80% of water or alkali reduced water. This is because, as shown in FIGS. It becomes difficult to charge, and when it exceeds 80% by weight, the ratio of urea and purified glycerol decreases, and the effect of lowering the vapor pressure decreases. 12 and 13, the horizontal axis indicates the day, and the vertical axis indicates the volume (cc) of the mixed solution.
That is, in the sealed portion of the S-type drain trap T shown in FIG. 11, when water is full (80 cc) to the overflow water level H, it evaporates in about 11 days (FIG. 12), whereas FIG. According to the graph shown in Fig. 2, the curve A when the sealed water is replaced with 90% of the water and used as the mixed sealed liquid 10 is 16 cc or less in about 360 days or more due to the reduction of the evaporation component, and the lower limit of the sealed water maintenance The water level is below the lower limit water level L of 17 cc, the water seal is broken, and bad odor from the sewage side is released into the room.
On the other hand, the curve B when the mixed sealing liquid 10 is replaced with 80% water of this agent becomes constant over 17 cc due to the reduction of the evaporation component in about 360 days or more, the sealed water is maintained, and the water 75 Curve C in the case of replacement with% of this drug becomes constant at 40 cc due to the decrease in evaporation component after about 360 days or more.
Therefore, the maximum percentage of water in this drug is 80%.

The pH value of the vapor pressure reducing agent 5 is 9.0 to 10.0. More preferably, it is set to 9.5 to 10.0. By making it alkaline, the effect of suppressing the growth of various bacteria is exhibited. The pH value may be adjusted with a pH adjuster or the like in consideration of the environment for microorganisms in the septic tank.
The specific gravity is set to 1.00 to 1.10, preferably 1.01 to 1.09, and more preferably 1.07 to 1.09. In other words, by making the specific gravity slightly heavier (larger) than water, it is possible to prevent the upper portion of the sealing water W from being biased like a supernatant liquid and to mix well with the sealing water W closer to the sewage side. Yes.
Moreover, the boiling point in atmospheric pressure shall be 120 to 130 degreeC. More preferably, the temperature is set to 125 ° C to 130 ° C. In addition, there is no flash point or ignition point, and safety is high.

  The following vapor pressure reducing agents in Table 1 were prepared.

50 cc of the examples (practical products) in Table 1 above (hereinafter sometimes referred to as “this drug”) and 50 cc of water (as an alternative to the sealed water W in the drain trap T) are mixed to 100 cc. FIG. 4 is a graph showing the results of experiments on the sealing liquid 10 (in the case of the mixed sealing liquid 10 with the concentration of this agent being 50%). The horizontal axis indicates the day, and the vertical axis indicates the capacity (cc). For comparison, FIG. 3 shows a case where 100% water is used as a 100 cc sealed water W (when the concentration of this agent is 0%). All are room temperature 27 degreeC.
As shown in FIG. 3, with only water, it evaporates and disappears in 12.5-13 days. In contrast, in the example (experimental example) shown in FIG. 4, 58 cc remains even after 540 days, and it is understood that about 40 to 50 cc of water should be replenished once every 10 months.

  FIG. 5 shows a case where 30 cc of this agent and 50 cc of water are mixed into an S-shaped drain trap T as shown in FIGS. 1 and 2 to obtain a mixed sealing liquid 10 of 80 cc (the concentration of this agent). It is the experimental result which filled the thing of (when it is 38%). The horizontal axis indicates the day, and the vertical axis indicates the capacity (cc). As shown in FIG. 5, 40 cc remains even after 540 days, and it is understood that the drain trap T may be replenished with about 40 to 50 cc of water once every 10 months.

Moreover, as shown in FIG. 6, the experimental result used for the bell-shaped drain trap T 'provided in a sink or a drain outlet is shown in FIG. 7 and FIG.
FIG. 7 shows that, for a bell-shaped drain trap T ′ having a maximum filling amount of 200 cc, 30 cc of this agent and 170 cc of water are mixed to give a mixed sealing liquid 10 of 200 cc (the concentration of this agent is 15%). It is the experimental result which filled it.
FIG. 8 shows that a bell-shaped drain trap T ′ having a maximum filling amount of 350 cc is mixed with 30 cc of this agent and 320 cc of water to obtain a mixed sealing liquid 10 of 350 cc (the concentration of this agent is 8.5%). ), And the experimental results of filling it. 7 and 8, the horizontal axis represents the day, and the vertical axis represents the volume (cc) of the mixed sealing liquid.

As is apparent from FIG. 7, about 75 cc remains after 300 days to 330 days (about 10 months), and it is understood that about 125 cc of water should be replenished once every 10 months.
Further, as is apparent from FIG. 8, about 150 cc remains after 300 days to 330 days (about 10 months), and it is understood that about 200 cc of water should be replenished once every 10 months.

As described above, the present invention also exhibits an excellent function and effect for suppressing evaporation. Depending on the season and the shape and size of the drain traps T and T ′, there is a slight difference in evaporability.
Further, when actually used (vapor pressure lowering method), if the mixed sealing liquid 10 with the maximum filling amount of the drain traps T and T ′ (sealing water) is 100%, the concentration of the vapor pressure reducing agent 5 is As shown in FIG. 1, it is desirable to add to sealed water W as shown in FIG. 1 so as to be 5 to 90%, preferably 8 to 70%. If the amount is less than the lower limit, the amount of evaporation is large, and there is a possibility that the drainage traps T and T ′ will be less than the minimum filling amount that exhibits the deodorizing and insect-proofing effect (sealing water) before 10 months have passed. Further, if the upper limit is exceeded, a sufficient evaporation reduction effect can be obtained, but a large difference cannot be obtained from the case where the concentration is set to the maximum value within the above numerical range, so that the vapor pressure reducing agent 5 is wasted. Because.

Next, the results of experiments on the freezing property (ease of freezing) of this drug are shown in FIGS.
FIG. 9 shows an experiment in which the mixed sealing liquid 10 obtained by mixing 25 cc of this drug and 75 cc of water (4 times dilution, concentration 25%, liquid temperature 25 ° C.) is left in a room (freezer room) at −22 ° C. It is the result.
FIG. 10 is a result of an experiment conducted when the mixed sealing liquid 10 obtained by mixing 50 cc of this agent and 50 cc of water (double dilution, concentration 50%, liquid temperature 25 ° C.) is left in a room at −22 ° C. . 9 and 10, the horizontal axis represents time (minutes), and the vertical axis represents temperature (° C.).

As is apparent from FIGS. 9 and 10, it can be seen that the temperature decrease has become moderate after the start of 50 minutes has passed. Thereafter, in the example (experimental example) of FIG. 9, it took 160 minutes to solidify (−11.2 ° C.). In the example (experimental example) of FIG. 10, it took 260 minutes to solidify (−18.3 ° C.).
Thus, the higher the concentration of this agent, the lower the freezing point, and the antifreezing action that increases the time until solidification (delays the time until freezing) is obtained. It is clear that has an excellent antifreezing effect.
Depending on the season and the shape and size of the drain traps T and T ′, there is a slight difference in freezing properties.

  Note that the vapor pressure reducing agent 5 of the present invention may be used in a toilet bowl. Moreover, it is also free to contain a disinfectant slightly as a component. Moreover, you may use for the refrigerant | coolant (water) for central heating.

  As described above, the water vapor pressure reducing agent of the present invention has urea, a surfactant, purified glycerol, and water or alkali-reduced water. In the ground, it can be used safely without freezing. Furthermore, it is difficult to evaporate and does not drought over a long period of time. For example, replenishment once every 10 months is sufficient. Furthermore, if it puts into a trap etc., it will mix with the sealing water W easily and naturally. Further, the present invention can be widely used for central heating refrigerant (water) and other freeze prevention, and can be applied to a wide range of applications in cold regions.

Moreover, since urea is 5 to 20% by weight, surfactant is 0.1 to 5% by weight, purified glycerol is 10 to 80% by weight, and the remainder is mainly water or alkali reduced water, there is little influence on the natural world, Vapor pressure is sufficiently reduced, so it can be used safely in cold regions without freezing.
Furthermore, it is difficult to evaporate and does not drought over a long period of time. For example, replenishment once every 10 months is sufficient. Furthermore, if it puts into drain trap T, T 'etc., it will mix with the sealing water W easily and naturally. In addition, there is no risk of ignition, no sedimentation occurs under the drain traps T and T ′, and solidified substances are not easily generated. In particular, the present invention can be applied to a cold region where the temperature is about -35 ° C.

Here, a vapor pressure reducing agent 5 will be described as an example of a method for preventing a drain trap from being broken.
As shown in FIG. 11, the vapor pressure reducing agent 5 is introduced so that the liquid level Ws is equal to or higher than the sealed water maintenance lower limit value in the sealed portion Ts of the S-shaped drain trap T. When the liquid level Ws of the sealing liquid 10 is less than the sealing water maintenance lower limit value, the liquid level Ws ′ (the one-dot chain line in the figure) of the sealing liquid 10 is below the upper part Tu of the curved part Tc in the sealing part Ts. Since the gap G is formed between the upper portion Tu and the liquid level Ws ′, the sealing function is not exhibited.

  For this reason, when the vapor pressure reducing agent 5 is introduced, the vapor of the vapor pressure reducing agent 5 is previously vaporized so as to ensure an amount of purified glycerol remaining above the lower limit of the sealed water maintenance in the sealed portion Ts of the drain trap T. A mixing ratio of purified glycerol in the pressure reducing agent 5 may be set. As a result, even if vaporized components such as water in the vapor pressure reducing agent 5 introduced into the sealing portion Ts of the drain trap T are vaporized, at least purified glycerol remains above the lower limit of the sealed water maintenance (the liquid level Ws is Therefore, the bad odor from the sewage side can be prevented from entering the indoor side, and the indoor environment can be maintained well. In addition, although demonstrated as a prevention method of the drainage trap of the drain trap using the vapor | steam pressure reducing agent 5, when the antifreezing agent is used, it is the same. Moreover, since the lower limit value of the sealed water maintenance varies depending on the shape and size (volume) of the drain trap, the input amount and / or the mixing ratio of the purified glycerol in the vapor pressure reducing agent 5 may be appropriately adjusted according to these. .
