Description

Environmentally friendly trace element liquid fertilizer manufacturing equipment {AN APPARATUS FOR MANUFACTURING ECO-FRIENDLY TRACE-ELEMENT FERTILIZER}

The present invention relates to a liquid fertilizer manufacturing apparatus, and more particularly, to an environmentally friendly trace element liquid fertilizer manufacturing apparatus comprising a trace element liquid fertilizer that ion-leached the inorganic trace nutrients contained in natural ore with high efficiency.

Nutrient sources of most known crops in the soil are in the form of dozens or hundreds of cations and anions or compounds and are mainly absorbed through the roots.

 The essential nutrients for plant growth are called 'essential nutrients', which are largely divided into six (N, P, K, Ca, Mg, S) nutrients and micronutrients (Fe, Cu, Zn, Mn, Mo, B, Cl). Doing.

However, in Korea, about 55% of the soil is made of granite-based quartz, feldspar, muscovite, etc., and is an acidic soil with little inorganic nutrients. .

In general, nutrients present in the soil are not only lost to groundwater and rivers due to weathering such as snow or rain, but also lost to groundwater and rivers. When harvested in the same place, nutrients in the soil are depleted, so the yield and nutritional content of the crops are It will fall gradually.

In addition, although the amount of mineral nutrients required by the plant is very small, if any one component is out of balance or lacks a significant amount, it causes a physiological disorder of the crop, and these physiological disorders are not easily recovered, resulting in impairment of plant growth in farms. It is a huge economic loss.

Table 1 below shows the classification of nutrients required for plant growth.

In order to solve the above problems, artificially replenishing nutrients that are lost and depleted in the soil is artificially referred to as a fertilizer. Fertilizers are defined as 'substances that cause chemical changes in the soil to nourish plants or help cultivation of plants, substances that nourish plants, and other materials for soil improvement prescribed by Ordinance of the Ministry of Agriculture, Food and Rural Affairs.' (Article 2 of the Fertilizer Management Act)

In recent years, due to the development of inorganic (chemical) quality fertilizers, inorganic (chemical) quality fertilizers are generally used in farming fields such as rice fields, fields, or greenhouses. However, inorganic (chemical) fertilizers have the advantage of increasing the amount of crops in a short period of time due to their fast-acting properties, but excessive use can deepen soil acidification, physiological disorders, pests, etc., and excessive input of fertilizers, nutrients, etc. This can lead to developmental and nutrient imbalances, which can lead to continuous disturbances.

To solve these problems, the government implemented the 'Environment-friendly Agriculture Promotion Policy' in 1997, encouraging the use of environmentally friendly fertilizers, while the use of inorganic (chemical) fertilizers decreased while the use of eco-friendly organic fertilizers increased.

However, the organic fertilizer manufacturing company mainly manufactures and sells unfermented compost using sawdust, and the unfermented compost generates a lot of odors due to gas such as ammonia generated after fertilization, and farms due to problems such as crops not growing. In the case of avoiding the use of the organic fertilizer manufactured and marketed has been generated.

In addition, in recent years, organic fertilizers are manufactured and sold by mixing and fermenting livestock manure with briquettes and sawdust. However, in the case of organic fertilizers using livestock manure, odor occurs during spraying, causing complaints to the surroundings, while plants are libihy According to the law of the minimum amount of, it absorbs various elements based on the smallest amount of all the elements that it can absorb. Organic fertilizers contain little inorganic nutrients, so various ingredients necessary for plant growth Since there is a limit to supplying them in a balanced manner, for plant growth, continuous infusion of mineral nutrients in addition to organic ingredients is required.

Currently, in the agricultural and horticultural field, research on fertilizers capable of effectively providing such mineral nutrients is widely conducted, and as described above, there are six nutrients to be supplied to plants (N, P, K, Ca, Mg, S) Nutrient and micronutrients (Fe, Cu, Zn, Mn, Mo, B, Cl) are mainly used. The six major nutrients are sprayed on the soil in the form of a single salt, and the micronutrients are water-soluble and are applied to crops in a foliar state. I am using it.

That is, referring to Figure 1, N, P, K of the six major nutrients are important nutrients to increase crop productivity, and Ca, Mg, and S are utilized as nutrients necessary to increase quality, photosynthesis, taste, and aroma. . Micronutrients are used to increase fruit shape, size, and shoots.

However, in the case of using chemicals to produce various complex micronutrients necessary for plants by mixing these nutrients, the manufacturing process is not only dangerous, but also lacks to satisfy consumers' high preference for eco-friendly agricultural products. In the case of using microorganisms, long-term use is due to the loss of organic matter with low soil adsorption capacity in terms of environment due to the long manufacturing time and large amount of organic components, and the persistence of fertilization effect is low, and contamination of groundwater such as arsenic and nitrate nitrogen and nearby May cause eutrophication of water quality.

In addition, the conventional trace element fertilizer does not have N, P, K, etc., and contains trace amounts of trace elements, and is distributed at a price similar to the four-piece ratio, causing confusion of fertilizer prices and increasing cost of farming. Due to this, most farms are self-sufficient to produce and use fertilizers, but the manufacturing method is very dangerous, and it is difficult to guarantee the nutrient content, and damages caused by overspray and crop failure occur.

Therefore, the elution concentration can be improved in a short period of time compared to a conventional method using only water. In addition, bubbles of sulfur vapor can be aerated by the stirring action of the stirrer 230 so that the ion dissolution reaction in water can be effectively performed.

A method of manufacturing an environmentally friendly specific element using the environmentally friendly trace element liquid fertilizer manufacturing apparatus according to an embodiment of the present invention having the above configuration will be described in detail.

2 to 4, first, natural sulfur is generated by heating natural sulfur in a heat treatment reactor 100 with a heater 120 (S10).

The sulfur vapor generated in the step (S10) is supplied to the mineral elution tank 200 and aerated into the mineral turbid solution (S12). Then, by the aerated sulfur vapor, the pH of the natural mineral powder is greatly lowered, so that mineral elution is accelerated, and a large amount of minerals can be eluted in a short period of time (S14).

That is, while the sulfur vapor generated in the reaction tank 100 meets with water in the elution tank 200, the natural ore powder solution (turbid solution) decreases from pH7 to pH2, thereby promoting mineral elution. In addition, by the physical action between natural ore powders due to the stirring action of the stirrer 230, the particle size is made into finer particles, thereby expanding the reaction area capable of eluting underwater ions to promote the rate of mineral dissolution, thereby promoting the existing water. It is possible to significantly reduce the rate of mineral elution compared to elution using only bays.

As in the step (S14), when the mineral aqueous solution in which the natural mineral is eluted reaches a certain concentration or more, the filter 240 is passed to filter the natural mineral powder (S16), and a pure mineral aqueous solution can be obtained (S18). . The mineral aqueous solution thus produced contains various trace elements eluted from natural minerals, so that it can be used as an environmentally friendly trace element fertilizer. In particular, it is possible to manufacture only natural minerals and water, which are eco-friendly raw materials, not conventional chemical methods.

On the other hand, sulfur residues remaining in the air after being used for natural mineral elution in the step (S14) are safely treated through a subsequent treatment process (S20). That is, the step (S20) may process the sulfur component through the cleaning tank 310 described above, wherein the cleaning liquid (processed water) containing the sulfur residual component can be reused by resupplying it to the elution tank 210. (S22).

In addition, it is recommended that the treatment step (S20) is repeated a plurality of times depending on the capacity and frequency of use of the environmentally friendly trace element fertilizer manufacturing apparatus so that sulfur residues can be safely processed and discharged. In this case, the cleaning tank 310 may be configured by connecting a plurality of series or parallel.

In addition, an example in which a trace element is eluted from a natural mineral using the eco-friendly trace element fertilizer manufacturing apparatus of the present invention will be described.

Experimental Example Experimental conditions: The ore powder used was natural sulfur, magnesia stone, borax stone, manganese stone, wollastonite, blast furnace slag, mixed with 5 g of ore powder (1 g each) in 200 g of water, and 6.5 g of sulfur. The mixture was heated to 100 ° C and vaporized to agitate in a mineral reaction tank, followed by stirring for 2 hours, and then measured by ICP-OES.

Comparative Example Experimental conditions: the same as the experimental conditions of the experimental system, aeration was performed for 2 hours without using only sulfur, followed by agitation and then measured by ICP-OES.

The results of the experiment are shown in Table 2 below.

As can be seen from the above experimental results, according to the present invention, it is possible to produce a large amount of environmentally friendly trace element liquid fertilizer in a short time without additional chemical treatment. Therefore, it is possible to safely produce eco-friendly microelement liquid fertilizer at low cost and distribute it to the farm, thereby increasing the yield of farm crops and increasing the income while reducing the cost of cultivation.
