Description

  The present invention relates to a seal water evaporation inhibitor.

  Conventionally, drain pipes such as washstands and sinks have been provided with drain traps for storing sealed water in order to prevent bad odors from entering the room from the sewage side and living organisms such as pests into 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 the sealing water from evaporating, oil (sealing water evaporation inhibitor) is introduced into the sealing water to cover the water surface (see, for example, Non-Patent Document 1).

  However, the specific gravity of the oil is lighter than that of water, and it is difficult to move the sealed water from the drain port side to the sewage side when the sealed water evaporation inhibitor is added. Further, as shown in FIG. 4, oil (sealed water evaporation inhibitor) cannot enter the dirt layer adhering to the inner wall of the drain pipe, and as shown by an arrow X in FIG. There is a possibility that water enters and rises into the dirt layer, whereby the sealed water W evaporates (the drain trap T is drowned).

  The problem to be solved is that it is difficult to move the sealed water from the drain outlet side to the sewage side when the sealed water evaporation inhibitor is introduced. In addition, oil cannot enter the dirt layer adhering to the inner wall of the drain pipe, and the sealed water will evaporate after entering and rising into the dirt layer (the drain trap T will be drought). It is.

Therefore, the sealing water evaporation inhibitor according to the present invention is mainly composed of a water-soluble liquid in which 0.98 ≦ ρ <1.0, where edible waste oil is emulsified and the specific gravity is ρ.
Moreover, the said cooking waste oil is made into B waste oil.
Moreover, it emulsifies so that an emulsified state may continue for at least 3 months.
In addition, 80% to 95% of edible waste oil is emulsified.
The emulsifier is an alkaline detergent.

  According to the seal water evaporation inhibitor of the present invention, when the seal water evaporation inhibitor is introduced, the seal water can be easily moved from the drain port side to the sewage side. Moreover, clogging after entering the dirt layer adhering to the inner wall surface of the drain pipe can prevent the sealing water from evaporating from the dirt layer. That is, it is possible to prevent the drain trap from being drought.

It is explanatory drawing which shows the use condition of one Embodiment of this invention. It is a principal part enlarged view of FIG. It is explanatory drawing which shows the usage method. It is explanatory drawing which shows the use condition of a prior art example. It is explanatory drawing which shows the test method of an Example. It is explanatory drawing which shows the test method of a comparative example.

  FIG. 1 is an explanatory diagram showing a use state of an embodiment of the present invention. In order to prevent the sealing water W from evaporating, this sealing water evaporation inhibitor E is used, for example, by being introduced (inflowed) into the drain trap T of the drain pipe H. Specifically, the sealing water evaporation preventing agent E prevents the sealing water W from evaporating by covering the water surfaces M on both the sewage side G and the drain outlet side K of the sealing water W.

  The anti-sealing agent E is mainly composed of a water-soluble liquid satisfying 0.98 ≦ ρ <1.0, when food waste oil is emulsified and the specific gravity is ρ. When the specific gravity ρ is ρ <0.98, the separation speed from the sealed water W after flowing into the sealed water W is high, and the working efficiency is deteriorated. Moreover, when specific gravity (rho) is 1.0 <= (rho), it does not isolate | separate to the water surface M of the sealing water W, but settles on the bottom of the sealing water W. The cooking waste oil is preferably B waste oil, for example.

  It is emulsified so that the emulsified state lasts for at least 3 months. For example, edible waste oil is emulsified to 80% to 95% by mechanical emulsification. That is, 80% to 95% of the edible waste oil is emulsified. When the ratio of emulsification is within the above range, the inside of the sealed water W can be easily moved from the drain outlet side K to the sewage side G. Further, the sealing water W can be prevented from evaporating from the dirt layer S by clogging after entering the dirt layer S (see FIG. 2) adhering to the pipe wall inner surface N of the drain pipe H. In addition, after a predetermined time has passed after flowing into the sealed water W, it is separated into the water surface M of the sealed water W.

  When the rate of emulsification is less than 80%, it is difficult to move from the drain outlet side K to the sewage side G in the sealed water W. Further, it is difficult to enter the dirt layer S (see FIG. 2) adhering to the pipe wall inner surface N of the drain pipe H, and there is a possibility that the sealed water W evaporates after entering and rising into the dirt layer S. When the rate of emulsification exceeds 95%, the sealing water evaporation inhibitor E that has flowed into the sealing water W completely dissolves in the sealing water W and does not separate into the water surface M of the sealing water W. The emulsifier is preferably, for example, an alkaline detergent (manufactured by Smart Wash, Inc. Smart).

  As shown in FIG. 2, the sealing water evaporation inhibitor E enters the dirt layer S adhering to the inner wall surface N of the drain pipe H, and then raises the dirt layer S as shown by an arrow A in FIG. 2. The water evaporates and, for example, in the range Z in FIG. 2, the oil component starts to clog, and thereafter, the range Z gradually clogs so as to expand downward. Thereby, the sealing water W cannot rise in the dirt layer S to a height above the liquid level (boundary surface with air) P of the sealing water evaporation inhibitor. That is, the sealing water W can be prevented from evaporating from the dirt layer S.

  FIG. 3 shows a method of using the sealed water evaporation inhibitor E of the present invention. That is, the sealing water evaporation inhibitor E is poured from the drain outlet side K into the sealing water W (see FIGS. 1 and 2) in the drain trap T (inflow). The sealed-water evaporation inhibitor E that has been introduced (inflowed) diffuses in the sealed water W, and a part of the sealed-water evaporation inhibitor E passes through the sealed water W as indicated by an arrow C in FIG. Move to G. Thereafter, as shown in FIG. 1, the sealing water evaporation inhibitor E covers the water surface M of the sealing water W.

  Next, as shown in FIGS. 5 and 6, a model test for comparison was performed using the seal water evaporation inhibitor E of the present invention and the conventional seal water evaporation inhibitor L. As Example 1, 100 cc of smart wash was added as an emulsifier to 100 cc of B waste liquid, and sealed water evaporation inhibitor E was prepared by emulsifying 95% of B waste liquid by mechanical emulsification. As a comparative example, a new palm oil was used (sealed water evaporation inhibitor L).

As shown in FIG. 5, 50 cc of water W ₀ was placed in a beaker Y having a diameter of 80 mm, and 50 cc of the sealed water evaporation inhibitor E of Example 1 was added. Further, as shown in FIG. 6, 50 cc of water W ₀ was put into a beaker Y having a diameter of 80 mm, and 50 cc of the sealed water evaporation inhibitor L of Comparative Example was added. Each beaker Y, as an alternative to the previously soiled layer S (see FIGS. 2 and 4), as well as arranged along the sidewall Y ₁ beaker Y gauze cloth piece F, part to the outside of the beaker Y allowed to depend from the upper edge Y ₂ of the beaker Y.

In the case where the sealed water evaporation inhibitor E of Example 1 shown in FIG. 5 was added, the capillary phenomenon disappeared after 10 minutes, and after 5 hours, the amount of water W ₀ in the beaker Y decreased to 49 cc. There was no change in the amount of water W ₀ in the beaker Y. That is, the water W ₀ was not evaporated. In the case where the sealing water evaporation inhibitor L of the comparative example shown in FIG. 6 was added, almost all of the water W ₀ that was in the beaker Y after 20 minutes to the outside of the beaker Y via the gauze cloth piece F due to capillary action. moved.

  From the above, it is considered that the sealing water evaporation preventing agent E of Example 1 entered the gauze cloth piece F and then dried in the gauze cloth piece F to cause clogging of the oil. Moreover, it is thought that the sealing water evaporation inhibitor L of the comparative example did not permeate into the gauze cloth piece F. The dirt layer S formed on the pipe wall inner surface N of the drain pipe H into which the sealing water evaporation inhibitor E according to the present invention is charged has a structure having a large number of fine gaps, and the gauze cloth piece F has the same structure. In the structure having a fine gap, the above-described model test produces the same result as the drain pipe H having the actual soil layer S.

In addition, you may use the sealing water evaporation inhibitor E of this invention thrown into the toilet bowl of a western style toilet. It is possible to prevent evaporation of water in the toilet bowl.
The present invention can be modified in design, and for example, a disinfectant may be contained in advance. It can have a sterilizing effect.

  As described above, when the waste oil is emulsified and the specific gravity is ρ, the present invention mainly comprises a water-soluble liquid satisfying 0.98 ≦ ρ <1.0. In the sealed water W, it is possible to easily move from the drain outlet side K to the sewage side G. In particular, since the specific gravity ρ is close to the specific gravity of water and it is emulsified, the separation rate from the sealed water W after flowing into the sealed water W is slow (for example, 5 hours), and the working efficiency is good. Further, the sealing water W can be prevented from evaporating from the dirt layer S by being clogged after entering the dirt layer S adhering to the pipe wall inner surface N of the drain pipe H. Furthermore, edible oil contains, for example, about 20% glycerin. Since glycerin has a hydrophilic group and a lipophilic group, the emulsified state can be maintained for a long time. Moreover, freezing of piping in a cold region can be prevented by containing glycerin. For example, freezing to -8 ° C can be prevented.

In addition, since the cooking waste oil is the B waste oil, the B waste oil having a narrow use can be effectively used. Moreover, the sealing water evaporation inhibitor E can be manufactured at low cost. Furthermore, when emulsified, it looks yellow and the appearance is good. That is, it looks natural even if it is not colored, has no sense of incongruity, and is a clean color, so it is also suitable for use in toilets.
Further, since the emulsification is carried out so that the emulsified state lasts for at least 3 months, it is possible to prevent the sealed water W in the drain trap T from being drowned even when water is not flowed for a long time. That is, it is possible to prevent the sealing water W from evaporating over a long period of time.

Moreover, since 80% to 95% of the edible waste oil is emulsified, the inside of the sealed water W can be easily moved from the drain outlet side K to the sewage side G. Further, the sealing water W can be prevented from evaporating from the dirt layer S by being clogged after entering the dirt layer S adhering to the pipe wall inner surface N of the drain pipe H. In addition, after a predetermined time has passed after flowing into the sealed water W, it is separated into the water surface M of the sealed water W.
Moreover, since an emulsifier is an alkaline detergent, it has a rust prevention effect. Moreover, when oil flows in, oil stains can be prevented.
