Description

Removal method of odor using plant extract {Removing method of odor gas using plant extract}

In order to neutralize the hydrogen sulfide gas (H ₂ S), which is an odorous substance, the plant extract extracted by the existing distillation method is proposed to provide an appropriate dilution method and conditions for applying and removing hydrogen sulfide.

In the present invention, conventional methods for purifying malodorous gas can be generally divided into physicochemical treatment techniques such as adsorption by activated carbon, chemical liquid cleaning, combustion, and biological treatment techniques using microorganisms. Physical and chemical deodorization technology has the advantage that it is easy to cope with odor load change, while the installation cost is relatively expensive, and it requires technical and economical methods such as requiring consumable materials such as activated carbon, chemical liquid, fuel, and the treatment of secondary pollutants. In terms of disadvantages. Biological treatment technology, on the other hand, requires a fairly large installation area in the case of odor removal, increases power costs due to pressure loss, and limits the amount of air flow. The development of technology related to such deodorization is aimed at environmental facilities. To date, there have been known cases in which ozone or ultraviolet rays are applied to a system as an oxidant to remove odors, or such a facility is used in a composting facility.

However, in the conventional case, among the various odor removal methods as described above, the removal method using microorganisms, the oxidation method using ozone or photocatalysts are often used locally because they require a separate device, and are relatively inexpensive. The adsorption method by zeolite is not only bad smell but also hinders the adsorption due to the property of absorbing moisture in the air, so there is little effect of removing odor and there is no treatment effect because there is no removal effect by chemical reaction.

In the past, the method of removing odor is a method of preparing a deodorant which is a natural deodorant that has a strong deodorant performance and harmless to humans or animals as the deodorant performance is maintained for a long time by mixing various substances extracted from native plants. Patent Registration No. 1981-0001124 discloses, the present invention is focused on improving the removal method by extracting the plant essential oil using the herbal medicine to absorb the odor component in a new device. Here, the plant essential oil extracts a component that removes hydrogen sulfide from the malodor component by neutralizing with the malodor component.

The prescription basis of the present invention has yet to be scientifically established the mechanism of action, but it has been shown to have a neutralizing effect on odor gas and the like. For example, as one of the solutions to the problems of the existing odor gas treatment technology, odor generating conditions such as dyeing, paper, leather, etc. can be widely used in many workplaces. Moreover, it is not only harmless to human body but also can give a good feeling because it can improve the working environment and give a friendly feeling to the workers due to the natural flavor of the plant.

The main subject of the present invention is to neutralize the malodorous gas using the components contained in the plant extracts using the chemical components of terpene, an essential oil component of the herbal medicine.

Plant essential oil, a volatile component present in herbal medicines, is a secondary metabolite of plants and has various physiological activities. It is a low-molecular substance extracted by water and its composition is confirmed by GC-MS. The main essential oils produced by the reaction were found to be monoterpenes. Table 1 shows the results of GC-MS analysis of plant extracts. The analysis method is to determine the molecular weight by mass spectrometry and the types of extract components by the results of instrumental analysis of GC-MS as shown in Figure 1. The plant essential oil components extracted from the herbal preparations used in the present invention are organic solvents such as plant essential oil components such as alcohols, aldehydes, ketones, ethers, esters and acids. The major components of plant essential oils were monoterpene and very small amount of sesquiterpene and diterpene. Especially in the case of monoterpene. As a result of the experimental analysis, eucalyptol, caryophyllen oxide, linalool, terpineol and longicamphenylone were identified. Experimental results showed that the components extracted in small amounts of less than 3% were fenchol, pinocarvone, and the like.

Table 1: Contents of main and plant essential oils of Figure 1 measured using GC-MS

Eucalyptol and carylophyllene oxide molecules, which contain epoxide compounds in monoterpene molecules, react with the malodorous components to undergo ring opening. L-linalool, fenchol, α, α, 4-trimethyl cyclohexanemethanol, borneol, β-eudesmol, α-terpineol, decahydro-1,1,7-trimethyl-4 with alcohol (-OH) groups in monoterpene and other molecules -methylene-1H-cycloprop [e] azulen-7-ol and 4-terpineol molecules neutralize with hydrogen sulfide to form salts and neutralize. The removal efficiency due to this neutralization reaction may depend on the initial concentration of the hydrogen sulfide to be removed and the dilution ratio of the plant distilled water extracted from the herbal preparation. Therefore, to prepare a deodorant for removing hydrogen sulfide at a low concentration to determine the initial hydrogen sulfide concentration and the dilution ratio of the plant distilled water obtained through the components of the plant distilled water obtained after the water bath, which is the plant extract proposed in the present invention, and to determine the proper use conditions. .

Hereinafter, the present invention will be described in detail.

All other plants have a unique odor and have the ability to break down odorous substances.

(Plant refinery analysis method)

Since the plant essential oil component is very volatile, the volatility is strong after the injection of the plant essential oil sample due to the elevated temperature of the sample inlet. Due to the volatility of the sample volume, accurate analysis is impossible, and in order to overcome this problem, an injection was attempted by attaching a head-space to recapture volatiles to a micro syringe syringe tube. In this experiment, SPME (Solid Phase Microextractiom) collection method was adopted, and a 65 μm high polymer hydrophobic (polydimethylsiloxane-Divinylbenzene) was installed inside the injection tube to extract the injection tube for 30 minutes at 25 ° C from the GC sample inlet. It was. This SPME was purchased from Supelco (USA).

Plant essential oil components are experimental conditions for GC-MS analysis as follows. The GC-MS used in the experiment was HP6890 and HP5973 (MSD) of Hewlett Packard, HP-1 (60 mm x 0.25 mm x 0.25 mm) for GC column, helium gas for carrier gas, and injection temperature 250 ℃, the temperature of the oven (oven) was increased from 50 ℃ to 240 ℃ to analyze the components. In the HP 5973 MSD, the mass range was 28-550 and the acquisition mode was quantified under scan mode.

(Measurement of removal efficiency)

Odor gas is introduced into the neutralization reactor through the inlet port to remove odor gas components, and the mixer mixes pure water and plant extract in a constant ratio. The injection nozzle in the reactor proceeded in the countercurrent contact direction inside the reactor, and the upper part of the reactor was sprayed with compressed air by compressed air and the hydrogen sulfide gas was introduced by upward flow at the lower part of the acrylic box so that the chemical neutralization reaction occurred. To remove hydrogen sulfide gas. In general, the experimental nozzles were deflected FLAT nozzles with spray angles of 130 to 140 ° and three orifice diameters of 0.41 mm, 0.84 mm and 1.4 mm. The spray spray flow rates according to the spray nozzle orifice sizes were 0.11, 0.45 and 1.4 l / min, width 200 mm and maximum air pressure of 5 kg _f / cm ² . As a result, the plant extract and the hydrogen sulfide gas reacted smoothly to adjust the reaction efficiency.

Hydrogen sulfide was artificially injected in an enclosed space size (400 mm x 400 mm x 600 mm) made of acryl to adjust the uniform hydrogen sulfide concentration to 50 ppm or less. The plant extract used was an aqueous solution in a pale yellow liquid phase. The actual dilution method used was diluted 5 times or more of plant essential oils. 20 ml of the diluted extract sample was injected into the hydrogen sulfide removal apparatus and measured using a hydrogen sulfide gas analysis detector tube according to the injection time. The gas scavengers used were made by Gastec (3 L). In the measurement of the experiment, the experiment was carried out by adjusting the temperature using a hot air blower in the sealed space.
