Description

  The present invention relates to a non-deliquescent granular fertilizer mixed with palm ash potash and a method for producing the same. .

Ash produced by burning palm bunches (Empty Bunch), which is a raw material for coconut oil, is a kind of plant ash used as an organic-derived potash fertilizer. The palm ash is called palm ash, and the potassium component is other plant ash. As it is very abundant compared to, it is used in potash fertilizer as palm ash potash.
However, since the palm ash potash fertilizer is powdery and has a small specific gravity, the fertilizer is likely to be scattered and washed away during fertilization work, and it is difficult to use both raw and top fertilizers.
As an example of a method for treating combustion ash fertilizer that is easily scattered during fertilization, Patent Document 1 adds 10 to 25% of water or an auxiliary agent to the combustion ash of palm palm to increase adhesion and cohesion, In the next step, organic fertilizers containing organic matter such as bone meal, rapeseed oil residue, fish meal, etc., and chemical fertilizers containing nitrogen, phosphoric acid, and potassium components are mixed and then granulated to increase density and prevent scattering. A method for producing molded fertilizers has been proposed.
Japanese Patent Laid-Open No. 5-194066

However, in the treatment method of Patent Document 1, even if scattering can be prevented by granulation, deliquescence develops when the amount of so-called palm insulator, which is a feature of potassium hydroxide, which is a potash component of the palm insulator, is large. Therefore, fertilization work becomes difficult, and it cannot be always used as a high-content potash fertilizer by the burning ash fertilizer of palm palm.
The present invention has been made in view of the above circumstances, and is mixed with palm ash potash fertilizer mainly composed of potassium hydroxide, chicken manure combustion ash mainly composed of calcium oxide, slaked lime composed mainly of calcium hydroxide, and the like. An object of the present invention is to provide a palm ash-kari mixed fertilizer and a method for producing the same, which are mixed fertilizer, made into calcium carbonate by contacting with carbon dioxide gas, and deliquescent.

  In order to achieve the above object, the non-deliquescent granular fertilizer mixed with palm ash potash according to claim 1 of the present invention has a particle diameter of 3 mm as a raw material with respect to the total 100 wt% contained in the granular fertilizer. Of 5% to 95% by weight of palm ash potash, powder containing at least one of the group consisting of chicken manure burning ash, quick lime, slaked lime, bitter lime lime, bitter slaked lime is blended in 95% to 5% by weight, And the amount of the binder which can maintain the shape of the particles granulated by the two raw materials is blended to eliminate the deliquescence of potassium hydroxide contained in palm ash potash.

  The method for producing a non-deliquescent granular fertilizer mixed with palm ash potash according to claim 2 is a method for producing a non-deliquescent granular fertilizer mixed with palm ash potash according to claim 1, wherein (a) particles A step of mixing powder containing at least one of the group consisting of chicken manure burning ash, quick lime, slaked lime, bitter lime lime, and bitter slaked lime with current palm ash potash 3 mm in diameter; and (b) the mixed powder A step of adding a binder in an amount sufficient to maintain the shape of the granulated particles to the body, (c) a step of granulating the kneaded product, and (d) carbonation while heating and drying the granulated product. And a step of contacting the gas with each other, wherein the deliquescence of potassium hydroxide contained in palm ash potash is eliminated during the production process.

The non-deliquescent granular fertilizer mixed with the palm ash potash of the present invention is calcium oxide contained in chicken manure burning ash and the like mixed with potassium liquefaction originally contained in palm ash potash. By mixing calcium carbonate derived from calcium hydroxide or calcium hydroxide, it becomes possible to eliminate the deliquescence of potassium ash potassium potassium hydroxide. For this reason, it becomes possible to eliminate the occurrence of deliquescence during storage and the particles becoming wet mud and adhering.
Further, since this fertilizer is granulated together with the binder, it can maintain the strength that the particles do not self-destruct, and does not cause pulverization due to drying, so that neither powder scattering nor runoff occurs during fertilization work.
Therefore, when spreading on the cultivated land, it becomes possible to disperse the fertilizer particles and perform the fertilization work without any trouble.
In addition, since it is treated with heavy oil combustion carbon dioxide during the manufacturing process, carbon dioxide such as calcium oxide and calcium hydroxide can be promoted and dried at the same time in a short time, enabling efficient mass production. It becomes possible to do.
Furthermore, from the viewpoint of waste disposal, it has become possible to use and consume more poultry manure generated in large quantities at poultry farms that had previously been difficult to dispose of as combustion ash and increase the compounding ratio to be used. Very beneficial.
In addition, the non-deliquescent granular fertilizer mixed with the palm ash potash of the present invention is to make palm ash potash non-deliquescent in addition to quick lime, slaked lime, bitter lime lime, bitter slaked lime and mixtures thereof. These can also be used as one of the fertilizer raw materials including non-deliquescent palm ash potash.

Embodiments of the present invention will be described below with reference to the drawings and tables.
The non-deliquescent granular fertilizer mixed with the palm ash potash of the present invention is a palm ash potash mixed fertilizer that does not have deliquescence and scattering properties, but as raw materials, chicken ash burning with chief ingredients such as palm ash potash and calcium oxide It uses ash, quicklime, etc., and is mixed with a binder such as molasses as an additive, and is molded into granules.
Hereinafter, the characteristic of the material used for this invention is demonstrated, and the characteristic of the non-deliquescent granular fertilizer which mixed the palm ash potash manufactured from the raw material is demonstrated.

Palm ash potash is a kind of plant ash made by burning the bunches (Empty Bunch) excluding the palm coconuts. Potassium hydroxide, which is the main component, is a major potash fertilizer because it contains much more potash components necessary for plants to grow than other plant ash.
An analysis table of the components of the palm ash potash is shown in Table 1 below.

The particle size of the palm ash potash used for this is set to a sieve size of 3 mm.
Since this palm ash potash raw material has a small bulk specific gravity as it is, it is a material that is difficult to use when it is fertilized and easily scattered in the wind.
In the present invention, such a palm ash potash raw material is mixed and dispersed with calcium oxide, calcium hydroxide, etc., and kneaded using a binder for granulation, so that the weighted particles are scattered to the target location in the cultivated land. It becomes possible to disperse without being.
Accordingly, when mixing and dispersing with calcium oxide, calcium hydroxide, etc., it is preferable that the particle diameter is 0.2 mm because the particle diameters are close to each other, so that the particles are easily mixed and dispersed.

On the other hand, potassium hydroxide, which is the main component of the palm ash potash, has the property of absorbing dehydration in the air and exhibiting deliquescent properties. It is difficult to use as fertilizer.
As a method of not exhibiting the deliquescent property, a method of forming a moisture-proof coating of calcium carbonate to prevent moisture from approaching, and a method of chemically changing to potassium carbonate to suppress moisture adsorption can be considered. The idea was to proceed with these methods in parallel.
And as the former method, attention was paid to chicken manure combustion ash as a material that forms a moisture-proof coating of calcium carbonate on potassium hydroxide, which is the main component of palm ash potash, to prevent moisture from approaching.
The chicken manure burning ash is produced by burning chicken manure at 900 to 1000 ° C., and contains calcium oxide as a main component.
Table 2 below shows an analysis table of the components of the chicken manure combustion ash.

As shown in Table 2 above, chicken manure ash contains 28.5% of CaO, and when water is added to this calcium oxide, it undergoes a hydration reaction and changes to calcium hydroxide, and then the water becomes steam. As it is released into the air, the calcium hydroxide absorbs carbon dioxide and gradually forms and hardens calcium carbonate, which is a moisture-proof coating, and prevents moisture from approaching.
In addition, quick lime and quick-lime quicklime can also be used as other materials that keep moisture away from potassium hydroxide, which is the main component of palm ash potash.

In any case, since the main component is calcium oxide, it causes a hydration reaction in the same manner as described above, further absorbs carbon dioxide gas, chemically changes to calcium carbonate, hardens, and prevents moisture from approaching.
Furthermore, slaked lime and bituminous slaked lime can be used as other materials that keep palm ash potash away from moisture, and mixtures thereof can also be used.
Since these are mainly composed of calcium hydroxide, they can absorb carbon dioxide and chemically change to calcium carbonate as described above, harden, and prevent moisture from approaching.

In the present invention, in addition to this, a binder is used to give strength so that the particles do not collapse.
Materials used as binders are water-soluble binders such as by-products of the sugar industry and molasses fermentation by-product concentrates, lignin sulfonate, corn steep liquor, CMC, etc. produced after the use of waste molasses in the fermentation industry. .
The palm ash potash fertilizer to be used in the present invention and chicken manure combustion ash are kneaded to form a bond, and granulated to a particle diameter of 1 to 10 mm and used in an appropriate amount so that they can be held at their own weight and not broken.

  Although each of the above materials has unique characteristics, an example of a blending table of non-deliquescent granular fertilizer mixed with palm ash potash according to the present invention is shown in Table 3 below, and non-deliquescent mixed with palm ash potash The manufacturing process of a granular fertilizer is shown in FIG. 1, and the chemical reaction state in this process is demonstrated.

The blends (1) to (4) in Table 3 above show four examples of the blending amount of the calcium-containing material with respect to the blending amount of the palm ash potash fertilizer.
In each of the above four examples, palm ash potash fertilizer and calcium-containing material pulverized under a 0.2 mm sieve are combined to 100% by weight, mixed with a mixer and kneaded with 4% by weight of the binder. It is.
The calcium-containing material may be any one of chicken manure burned ash, quick lime, slaked lime, bitter lime lime, and bitter slaked lime, or a mixture of two or more varieties thereof.

And as shown in FIG. 1, after mixing | blending and kneading | mixing based on the above Table 3, it granulates with a bread | pan type granulator or a rotary type granulator, and the intensity | strength which is not broken by self-weight is expressed.
The granulated mixed fertilizer has an outer diameter of about 1 to 10 mm to form the basic grain shape of palm ash potash fertilizer.
The palm ash potash fertilizer granulated in this way contains water, and potassium hydroxide, which is a palm ash potash fertilizer component, starts to dissolve in water and gradually becomes viscous. However, on the other hand, the calcium oxide derived from chicken manure burned ash, quicklime, and calcined quicklime blended in the palm ash potash fertilizer starts hydration reaction immediately with moisture to form calcium hydroxide, and after granulation, palm oxide The outer peripheral surface of the ash-kari fertilizer is stuccoed so that it does not collapse.

This calcium hydroxide suppresses further penetration of moisture into the granular material.
In addition, calcium hydroxide derived from slaked lime and bituminous slaked lime blended in this granular palm ash potash fertilizer is plastered on the outer peripheral surface of palm ash potash fertilizer after granulation, similar to the calcium oxide derived from calcium oxide, Granularity can be maintained without collapsing.
In the next step, the plastered calcium hydroxide absorbs carbon dioxide gas from the outside air and carbon dioxide gas from the carbon dioxide generator while releasing moisture to form calcium carbonate.
This calcium carbonate covers the outer periphery of palm ash potash fertilizer, and the palm ash potash fertilizer covered with calcium carbonate does not or does not easily occur.
The analysis table of the components of the palm ash potash fertilizer thus granulated is shown in Table 4 below.

  As shown in Table 4, granulated palm ash potash fertilizer contains 46.2% and a large amount of potassium hydroxide, but 21.2% and covered with a large amount of calcium carbonate. Is hard to get up.

On the other hand, when calcium carbonate is not formed even after granulation, that is, when only the palm ash potash fertilizer and binder as raw materials of the present invention are mixed and kneaded and granulated, the component potassium hydroxide is Deliquesce and gradually progress to a highly viscous liquid.
Therefore, when the mixture is kneaded and granulated and brought into contact with carbon dioxide gas, potassium carbonate, which is a composition that suppresses the adsorption of moisture, is formed, and the deliquescence is suppressed temporarily.
Furthermore, even when the amount of potassium hydroxide is small, potassium carbonate formed by contact with carbon dioxide gas can suppress deliquescence.

  In the above, a method for covering palm ash potash fertilizer with calcium carbonate, carbonated partially remaining potassium hydroxide to form potassium carbonate, and greatly reducing deliquescence over the long term has been described.

Next, the following steps can be considered as a mechanism for preventing deliquescence of non-deliquescent granular fertilizer mixed with palm ash potash in the above description. It can be greatly reduced.
That is, in the first step, the calcium hydroxide derived from calcium oxide starts to plaster by containing moisture, and the palm ash potash fertilizer grows in granular form while covering the potassium hydroxide derived from palm ash potash.
In the second step, the calcium hydroxide that has been plastered in the surface layer portion of the palm ash potash fertilizer that has grown in granular form comes into contact with carbon dioxide gas to form a calcium carbonate that is insoluble in moisture. Further, the carbon dioxide gas chemically modifies potassium hydroxide derived from palm ash potash fertilizer not yet coated with calcium carbonate into potassium carbonate.
In the third step, the granular palm ash potash fertilizer is dried to release moisture, and the moisture is prevented from penetrating into the granular palm ash potash fertilizer.

  In the above step, calcium oxide and calcium hydroxide are chemically changed to form calcium carbonate that is insoluble in moisture, greatly reducing the deliquescence of non-deliquescent granular fertilizer mixed with palm ash potash, and potassium hydroxide is carbonated. About the chemical change of potassium and suppressing the deliquescence of palm ash potash, the mechanism of the chemical reaction of the present invention is shown in Chemical Formula 1 and Chemical Formula 2, which are examples of the following reaction formulas.

As shown in the above chemical formula, water and carbon dioxide gas are required to establish this reaction formula, and water is supplied from a binder and carbon dioxide gas is supplied from a generator, and a chemical reaction is performed by a hydration reaction.
Conventionally, there is a method in which grass ash is dissolved in water to obtain an aqueous solution of potassium carbonate. However, since potassium carbonate is dissolved as an aqueous solution, particulate matter cannot be formed by evaporation of moisture.

The effect concerning the non-deliquescent granular fertilizer which mixed the above palm ash potash is demonstrated below.
Since the non-deliquescent granular fertilizer mixed with the palm ash potash of the present invention is covered with calcium carbonate or calcium carbonate derived from calcium hydroxide, the deliquescence is greatly reduced.
When the amount of potassium hydroxide, which is the main component of palm ash potash fertilizer, is small, liquefaction is not noticeable because it chemically reacts with carbon dioxide and changes to potassium carbonate.
Non-deliquescent granular fertilizer mixed with palm ash potash is granulated with a binder, and the particles are solidified to maintain a constant strength, so there is no scattering or runoff during fertilization work.

  Next, the non-deliquescent granular fertilizer mixed with the palm ash potash of the present invention was manufactured by changing the amount of blending, and when the relationship between the blending amount and deliquescence was examined, the results are as shown in Table 5 below. there were.

  In Table 5, for example, Example NO. 1 (quick lime) B, or Example NO. In 1 (quick lime) C, as a result of mixing calcium oxide or calcium hydroxide part 5 with palm ash potash part 95, it can be confirmed that this composition suppresses deliquescence of palm ash potash for 5 days or more. (In Table 5, a circle indicates that there was no deliquescence for 5 days or more).

  In addition, Example NO. In 3 (chicken manure ash) A, as a result of mixing the weight part 15 of the chicken ash calcined ash with the weight part 85 of the palm ash cali, it can be confirmed that this composition suppresses the deliquescence of palm ash potash for 10 days or more. (In Table 5, ◎ indicates that there was no deliquescence for 10 days or more).

Furthermore, Example NO. In 19 (chicken manure burning ash) A, as a result of mixing chicken manure burning ash weight part 95 with palm ash potash weight part 5, it was confirmed that this composition suppresses deliquescence of palm ash potash for 10 days or more ( In Table 5, ● indicates that there was no deliquescence for 10 days or more). However, this blend contains the least amount of palm ash potash, but chicken manure burned ash contains a large amount of potassium oxide and a large amount of calcium oxide. It has become.
In addition, Example NO. In No. 7, it was confirmed that the undepressed lime (D) and the (depressed lime lime) E also suppressed the deliquescence of palm ash potash for 10 days or more.

Example No. in Table 5 above. The method for producing No. 6 (chicken manure ash) A will be described in detail below.
In this production method, when producing a non-deliquescent granular fertilizer mixed with palm ash potash, a palm ash potash of 3 mm sieve in advance is pulverized using a pulverizer such as a ball mill, etc. The raw material of the present invention was crushed into potash.
Then, 70 kg of powdery palm ash potash under 0.2 mm sieve and 30 kg of chicken manure burning ash are collected and mixed with a ribbon mixer to knead 4 kg of lignin sulfonate (common name: lignin) as a binder. While granulating with a rotary granulator, the outer diameter was formed into granules having a size of about 1 to 10 mm, and the strength was not broken by its own weight.
Thereafter, the granular product was heated and dried while being reacted with carbon dioxide with heavy oil combustion carbon dioxide to produce a palm ash potash mixed fertilizer.
As another method, it is possible to produce a non-deliquescent granular fertilizer in which palm ash potash is mixed by allowing it to stand naturally after granulation and react with carbon dioxide in the atmosphere.
