Description

Deodorant for removing repellant odor using triple salt

The present invention relates to a deodorant for removing odor using triple salt, and more particularly, to remove odor generated from various odor generating sources including manure treatment plant, garbage dump, garbage incinerator, barn, sewage treatment plant sludge, food waste treatment plant, and the like. It relates to a deodorant for odor removal using triple salt for.

Malodors are generally distinguished by acidic odors such as hydrogen sulfide, methyl sulfide, methyl mercaptan, methyl disulfide, alkaline odors such as ammonia and trimethyl amine, and neutral odors such as acetaldehyde and styrene. In order to remove such odor-causing substances, the following deodorizing method is conventionally used.

The physical deodorization method is a method of removing odorous substances by adsorption and absorption of various porous adsorbents and is a method of adsorbing odorous substances using activated carbon, zeolite (Korean Patent Publication No. 90-256), activated clay, silica gel, and the like. This method is effective in removing the odorous substances in a short time, but there is no sustained use for a long time, there is a problem that the odorous substances are released again when the odorous substances are saturated in the adsorbent.

The chemical deodorization method is a method of deodorizing odor through chemical reactions such as desulfurization, neutralization reaction, redox reaction, addition condensation reaction and ion exchange reaction of various chemical substances with odor components. Representative examples include oxidation by chlorine dioxide (ClO ₂ ), ozone (O ₃ ), etc., calcium hydroxide (Ca (OH) ₂ ), calcium chloride (CaCl ₂ ), chlorine (Cl ₂ ), and cyanide solution (eg , Korean Patent Publication No. 2002-9337), Method of removing odor using copper nitrate (II) (Cu (NO ₃ ) ₂ ) and ferric nitrate (Fe (NO ₃ ) ₃ ) (Korea Patent 10-0821664), etc. There is this. In this method, it is difficult to expect a wide range of deodorizing effects on the entire malodorous substance because it is difficult to select chemically reactive substances that can act in common for different kinds of malodorous substances, that is, acidic, alkaline, and neutral. Some chemicals to be used as deodorants require considerable care in handling. The use of a composition mainly composed of chlorine dioxide or chlorine dioxide is effective in decomposing odor components due to the strong oxidizing power of chlorine gas, etc., but it cannot decompose itself in a short time and continuously removes odors. Chlorine gas or generator oxygen generated by self-decomposition may cause pollution to the surrounding environment or cause harm to the health of workers or people living in the vicinity.

Biological deodorization method is a method of suppressing the occurrence of odor by removing various microorganisms that cause the odor by spraying enzymes and preservatives to the source of the odor (Korean Patent Publication 93-002264). This method is used by directly spraying the deodorant directly to the odor source. The deodorizing effect is very slow and in most cases, the odor removing effect is insignificant.

Sensory deodorization method is a masking method that can not feel the odor by concealing the odor using a directional substance. This method conceals odorous substances so that they do not feel odors and can be unpleasant if the aromatics and odors are not balanced.

In addition, there is a method of using a catalyst calcined and reduced by supporting precious metal complex compounds such as Pt, Ni, Ru, Rh, Pd, Ag, Fe, Co, Ir on various carriers to remove odors. In this method, there is a problem in that the catalyst is poisoned by the components contained in the malodor and the life and efficiency are significantly reduced.

Sources and types of odors are so diverse that they are difficult to remove at the same time. In particular, the odor generated from food waste, manure, sewage sludge and the like varies depending on the source. The odor component contained therein is known to be difficult to remove due to various sulfur-containing compounds such as sulfur dioxide, hydrogen sulfide, mercaptan, alkyl sulfide, amines such as ammonia, nitrogen oxide, methylamine, aldehydes, indole, peptone, and the like.

Accordingly, an object of the present invention is to solve the above-mentioned problems, and to oxidize a wide range of bad smell sources generated from various odor sources including manure treatment plant, garbage dump, garbage incinerator, barn, sewage treatment plant sludge, food waste treatment plant and the like. It is to provide a deodorant that can be removed efficiently.

In this case, the content of water is 50 to 10,000 parts by weight, preferably 500 to 10,000 parts by weight based on 100 parts by weight of the triple salt in the deodorant composition for removing malodor. If the water content is less than 50 parts by weight, the ratio of raw materials is excessively economically undesirable, if the water content is more than 10,000 parts by weight oxidizing power is weak, the odor removal rate is lowered and the logistics cost is excessively increased. In use, the deodorant composition is preferably diluted in 2 to 1,000 times (by weight), preferably 30 to 500 times (by weight) of water in consideration of the state of the pollutant, and then sprayed onto the pollutant. .

The oxidizing agent used in combination with the triple salt is not particularly limited as long as it is a known oxide. For example, calcium peroxide (CaO ₂ ), potassium dioxide (KO ₂ ), potassium peroxide (K ₂ O ₂ ), magnesium peroxide (MgO ₂ ), ammonium persulfate ((NH ₄ ) ₂ S ₂ O ₈ ), ozone (O ₃ ), hydrogen peroxide (H ₂ O ₂ ), sodium percarbonate (2Na ₂ CO ₃ ˜3H ₂ O ₂ ), nitric acid ( HNO ₃ ), sulfuric acid (H ₂ SO ₄ ), perchloric acid (HClO ₄ ), hypochlorous acid (HClO), permanganic acid (HMnO ₄ ), chromic acid (H ₂ CrO ₄ ), sodium hypochlorite (NaOCl), calcium hypochlorite (Ca (OCl) ₂ ), persulfates such as sodium persulfate (Na ₂ S ₂ O ₈ ) or potassium persulfate (K ₂ S ₂ O ₈ ), salts of the aforementioned compounds, manganese oxide (Mn ₂ O ₇ ), Lead dioxide (PbO ₂ ), manganese dioxide (MnO ₂ ), cupric oxide (CuO), ferric chloride (FeCl ₃ ) or mixtures thereof.
