Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a treatment composition for treating waste oil from edible oil for tempura, frying, etc.

More specifically, it is characterized by gelling used waste oil with a polymer compound and a flammable water-soluble surfactant together with water and disposing of it as raw garbage or recycling it into soap, etc., and it is difficult to handle as garbage. The aim is to avoid emitting bad odors, harmful gases, and other pollution when secondary processing of garbage is carried out.

[Conventional technology]

Conventional methods for treating edible waste oil include hardening it with specific fatty acids (Japanese Patent Laid-Open No. 55-106298), turning it into soap (Japanese Patent Laid-Open No. 61-116000), and physically regenerating it by adsorption and filtration on natural white clay (Japanese Patent Laid-Open No. 1983-116000). Kaisho 59-813
98) Dispose of it by adsorbing it with pulp, nonwoven fabric, or other fibrous or spongy materials, or dilute it with an alkaline substance or surfactant and water, emulsify it, and use it as wastewater. In addition, various methods have been disclosed and put into practical use, including chemical recycling methods as part of the so-called waste oil soap movement, in which soap is recycled using strong alkaline substances such as caustic soda and caustic potash.

(Problems to be Solved by the Present Invention) The present invention provides a method for eliminating the complexity of waste oil treatment and processing waste oil in a safe and secure manner using an extremely simple method.

Among several conventional methods, the method of gelling waste oil with a specific fatty acid has attracted much attention, but since the gelling agent cannot be used unless the temperature reaches 80°C or higher, oil fires due to overheating and handling at high temperatures are possible. Because of this, it is easy to cause burns and other problems, which is causing serious problems regarding safety and security. The method of disposing of oil by absorbing it into a valve or sponge-like material also has a limit on the amount of oil that can be absorbed, which necessitates a larger capacity than necessary, resulting in high costs and increased space in the distribution process, making it inefficient. Ta.

Furthermore, the method of making soap involves the use of caustic soda or fire, which still leaves concerns about safety.

In addition, treating wastewater directly using surfactants causes secondary pollution, which is equivalent to discharging untreated oil into the watershed.

The present invention is a simple, safe and reliable composition that uses only natural raw materials, which can be made into a paste or gel by simply stirring (mixing) it with water and waste oil, and can be disposed of with the body waste or used as soap. The aim is to achieve secondary use in the field of technology.

Although the paste or gel-like material contains 40 to 60% water, it can be incinerated and is safe because it naturally decomposes without producing harmful substances even if it is burned.

(fJ) Means for Solving the Problem) The present invention uses a composition consisting of a hydrophilic polymer compound and a surfactant with an HLB of 7 or more to remove waste oil from 40 to 3
It is mixed with about 0% water to make a paste and disposed of.

If hot water (60''C or higher) is used instead of water, the paste will be more easily formed and the process can be carried out more reliably.

Examples of the hydrophilic polymer compound include the following, among which natural compounds are preferred from the standpoint of safety and processing ability.

If the polymer compound is more than the surfactant, the former is approximately 50 to 1) 5%, and the remainder is the normal proportion.

Two or more of these may be used in combination, and water or a water-soluble solvent such as ethylene glycol, propylene glycol, 1-3 phenylene glycol, lower alkyl cellosol, 4 M-grade alkyl carpitotol, lower alkyl: - Le,
It is also possible to disperse or dissolve it in advance in sorbitol or the like.

(Function) The present invention uses a hydrophilic polymer compound and an essential component of a surfactant with an L B of 7 or more as a composition, and waste oil, that is, a hydrophobic substance, forms a kind of emulsion gel through water.

Therefore, even if waste oil is edible, it may contain mineral hydrocarbons, solvents,
Another feature is that it can also solidify substances containing water-insoluble substances.

It's for a reason.

In addition, it is allowed to use preservatives in product formation.

Typical examples include parabens, benzoic acid, cations, chlorhexidine, and phenol.

Also, the amount of water depends on the strength of the paste, but it is 40 to 3
Although 00W% is common, it cannot be strictly regulated. The water used is preferably hot water of 60° C. or higher to improve dispersibility and emulsification.

Stirring should be done uniformly, but not uniformly.

The present invention provides a container for use with a specific surfactant (

There are large differences in both the cleaning ability of the container used and the paste strength of the prototype compared to the present invention.

It would also be possible to use a large amount of only a polymer compound, but this would be expensive and impractical.

(Effects) Thus, the waste oil treatment composition of the present invention provides the following special effects compared to conventional products.

■ Waste oil can be processed without overheating, so there is no need to worry about fires or burns.

■Paste prototypes can be disposed of by wrapping them in paper, such as Shinkai paper, and can be treated like garbage.

■High molecular compounds themselves are expensive, and if used in large quantities they can become paste-like, which is uneconomical and not only not suitable for disposal, but also takes a long time to develop into the best quality.

■Waste does not generate harmful or toxic gases or cause primary pollution.

■A small amount of treatment composition is required (approximately 40g to treat 1ρ of waste oil.
It is easy to commercialize the product in the distribution process.

■It does not require any special skills and can be easily processed by anyone by turning it into a paste within about 1 minute by stirring.
