Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention relates to a deodorizing agent for acidic malodor caused by humus and a method for producing the same.

Conventional Ω Revised Conventional deodorizers for acidic foul odors from deep beds and other organic sewage, waste, etc. can be generated by washing with water, alkaline washing, etc., or by a combination of ascorbic acid, humic acid, and iron salts. Adsorption by oxygen and various types of activated carbon are observed.

However, problems remain in post-processing when cleaning is used.
Also, those using oxygen have a short treatment life and have a slow oxidation rate, so the odor removal ability will decrease as the wind speed increases.

Activated carbons have a problem in that their performance decreases as the amount of water in the malodor increases.

The present invention has been made in order to solve the problems of the above-mentioned conventional methods, and its objectives are: (a) Powder particles that can be treated either for the source of the odor or for intensive treatment after collection. body or solid deodorizer.

(a) The powder or solid deodorizing agent composition is a combination of harmless substances so that it can be easily disposed of after being used to treat bad odors.

(1) Although oxidizing deodorizing agents have sufficient oxidizing power, their deodorizing power decreases as the wind speed increases. This can be overcome by combining and synchronizing adsorption and oxidation, selecting the oxidation catalyst, blocking the oxidant and catalyst metal, and strengthening the oxidant.

(1) To provide a deodorizing agent for acidic malodors and its production method by actively utilizing the moisture in the malodor in an oxidation reaction, etc. to form an active powder or solid substance.

[Configuration of the invention] Between raILiUILLuv? h c7) f 1st stage '' The deodorizer for acidic malodors using humus of the present invention is composed of active humus, a ligand that liberates a component with an oxidizing function in the active humus, and reacts with the active humus and the acidic malodor. Metals or their inorganic or organic salts that generate oxygen, film-forming substances that form a semipermeable film that finely blocks contact between activated humus and metals, and bond and adsorb acidic odors and generate hydrogen gas. It is characterized by being made by mixing metal hydroxides, and by adding excipients to each of these powders, inner layer molded products such as pellets, spheres, honeycombs, plates, or wire mesh shapes can be created. The solid deodorizer is produced by forming a film on its outer layer with a metal hydroxide and an excipient that adsorbs and binds acidic odors and generates hydrogen gas. A semi-permeable film-forming substance that finely blocks contact between active humus and metals or their inorganic or organic salts is kneaded together with a ligand that liberates components with oxidizing function, and active humus and acidic odor are removed. Oxygen-generating metals or their inorganic or organic salts are added and kneaded again to form solids such as pellets, spheres, honeycombs, plates, or wire mesh, and the outer layer binds and adsorbs acidic odors. It is characterized by forming a film using a metal hydroxide and an excipient that generate hydrogen gas and then drying the film.

The active humus powder contains 5% or more of fulvic acid, 3% or more of humic acid, and 5% or more of clay minerals.
Contains 2% or more of lignin and has a moisture content of 50 to 75%.

In addition, in the inner layer described in 2. (a) Adding a ligand to the active humus, fulvic acid, etc., which is the main body of the oxidation reaction, is removed from surrounding lignin, cellulose, etc. It becomes easier to react.

(b) The semipermeable film formed in the active humus prevents reactions caused by contact between the active humus and metals or their salt compounds, and prevents oxidation reactions from occurring until bad odors and moisture pass through the film. The active humus and the above-mentioned catalytic metals are divided into small parts. The sustainability of the reaction is improved because the reaction continues until the active humus is exhausted in that compartment and then passes to the other compartment.

(1) Hydrogen generated in the outer layer converts oxidized fulvic acid, etc. in the inner layer into a reduced form, so that the oxidation reaction starts faster and the reaction force increases.

The mixed composition of metal hydroxide and excipient in the inner layer is
It binds and adsorbs acidic odors such as hydrogen sulfide and retains them, thereby providing a site for oxidation by oxygen generated from the inner layer. The hydrogen gas generated by the combined adsorption and the moisture contained in the malodor bring the active humus and metals into contact through the semipermeable inner layer to initiate oxygen generation, synchronizing adsorption and oxidation.

Not implemented An embodiment of the present invention will be described below.

The above pellets include active humus powder (moisture content: 50
~75%), sodium ethylenediaminetetraacetate and sodium allegate are added and kneaded, iron powder is added and kneaded, and the viscoelasticity is adjusted before molding.

After drying to a moisture content of 40 to 45%, a mixture of calcium hydroxide, anhydrous calcium sulfate, and water is added and mixed, and then mixed with calcium hydroxide powder to form layer A, with a moisture content of 60%. %.

The oxidizing power of hydrogen sulfide in the above acidic odor dehydrating agent is 400 at a wind speed (1.3 m/sec/em') per Ikg of deodorizing agent.
It is g.

[Effects of the Invention] The present invention has the following characteristics: (a) In order to facilitate disposal after use, harmless raw materials are used as a composition; (b) In order to cope with any concentration of bad odor, Strengthen the oxidizing power of humus by adding ligands and selecting a metal catalyst, suppress the production of peroxide due to excessive oxidation, and improve the durability of deodorization by withstanding the wind speed that traps bad odors. Therefore, the oxidation and binding adsorption functions are divided into inner and outer layers, and their actions are synchronized, and the inner semipermeable membrane is used to subdivide the oxidation action in each subdivision, improving the sustainability of the oxidation reaction. (1) It can respond to changes in malodor concentration and collection wind speed by proactively using the moisture coexisting in malodors as a promoter of oxidation reactions, and is sustainable, active, and easy to dispose of after use. It can be made into an economical and easy-to-use acidic malodor deodorizing powder or solid material.
