Description

Manufacturing Method of Solid Solid Fuel Using Citrus Foil {Manufacturing Method of substitute solide fuel using mandarin waste}

The present invention relates to a method for producing a solid alternative fuel that can replace the existing fuel and is one field of waste solid fuel (RDF), in particular using citrus foil, which is an industrial waste generated after juice production from the tangerine complex processing plant It relates to a method for producing a solid alternative fuel.

[Document 1] Utility Model Registration 0277177 Korea 22 May 2002

The present invention relates to a fuel manufacturing method for manufacturing a solid alternative fuel for heating in the winter by using citrus foil, more specifically, briquettes, gas and commonly used for winter heating of farming plant farming facilities Etc., there is an object to be manufactured so that it can be used in place of diesel.

In the past, briquettes used in winter have difficulty in automatically exchanging briquettes, and a large amount of carbon monoxide is generated, which adversely affects the environment and the human body, and despite the low price, the supply of coal briquettes gradually decreases. In the case of kerosene and diesel, cultivated crops are gradually losing their external competitiveness due to the high cost of plant growing farmers due to the high cost.

There are many alternative energy that can be used, such as solar, solar, wind, geothermal, etc., but there are many difficulties in using it for farms due to excessive investment.

Citrus gourds from the citrus multiprocessing plant also have over 80% moisture content, which makes them difficult to use directly as fuel in farms without specific processing.

In addition, the citrus gourd provided from the citrus complex processing plant is not equipped with a shape, and thus it is not easy to use the boiler for a certain boiler, so there are many difficulties in using it in a farm.

The present invention has been invented to solve the above problems, the first object of the present invention is to replace the excessive energy costs and uncomfortable briquettes and diesel in the winter of the facility cultivation farmers cheaper than briquettes and the same energy calories per weight unit The present invention provides a method of reducing the cost of cultivating crops of facility cultivated farmers by providing the present invention with a low-cost present invention having 4500 Kcal / kg).

It is a second object of the present invention to provide a recycling method that can be usefully used as an alternative fuel by using citrus foil that is dumped in the sea without being recycled at an industrial site.

Citrus foil substitute fuel manufacturing process of the present invention is largely manufactured through a first drying process, a molding process, a second drying process.

Citrus gourd from the initial citrus complex processing plant contains more than 80% of water, so if it does not necessarily lower the water content, it cannot be molded without pressure in the extruder during molding. It should go through the first drying process to lower the moisture. At this time, it can lower the moisture through artificial drying facilities such as hot air drying, microwave drying, infrared drying, and freeze drying, but it can have a huge impact on the cost increase of the product. It is effective to choose natural drying methods such as ventilation drying. However, in order to dry a large amount of citrus gourd within a unit time, a drying method in which a bottom-up blower is attached to the bottom of a chimney-type silo with natural drying and artificial drying to evaporate moisture by upward ventilation is more effective.

Otherwise, as a way to lower the citrus gourd with more than 80% moisture to 60% or less, it is possible to lower the moisture content by adding sawdust, starch, bran, rice hull, rice straw, etc., which have low moisture content. In particular, the addition of these fibers helps to maintain the molding during molding and lowers the moisture content, which is very helpful for fuel production. However, this too can have a significant impact on manufacturing costs, so in some cases it would be reasonable to use additives when necessary.

In the second process, the molding can be performed by using an extruder and a press. Since the press has low product productivity, it is effective to use an extruder that can be continuously produced. The extruder is equipped with a heater that maintains a temperature of 200 degrees Celsius or more, which assists in molding and lowers moisture at the final exit of the product. And the pressure of the extruder should be maintained inside the extruder at least 800KG per square centimeter to maintain sufficient molding. The size or shape of the product is determined by attaching it to the outlet, the last part of the extruder.

The second drying process, the third process, contains less than 50% moisture, so there is no problem in appearance, but it can be spoiled if the water is not lowered to less than 10%. It is sent directly to the artificial drying facility to lower the moisture. At this time, the drying method that can be used may include hot air drying, microwave drying, infrared drying, freeze drying, etc., but when using hot air drying, the use of alternative fuel of the present invention is more effective in terms of cost.

By using the method as described above, by fueling citrus gourd, which is difficult to use as a fuel due to its high water content, it is cheaper than briquettes to supply plant farms with lower costs. It works.

It recycles and recycles citrus foil discarded by ocean dumping, which induces energy import substitution effect and makes waste of citrus complex processing plant that is not easy to process by reducing waste disposal cost and contributes to profitability of citrus plant. have.

Even after the solid fuel of the present invention is burned, the remaining ash is not detected by heavy metals, so that the remaining ash is sprinkled on the field to give a fertilizer substitute effect.

Hereinafter, the alternative fuel manufacturing process according to the present invention will be described in the form of an embodiment.

1 is a system configuration showing a manufacturing process according to an embodiment of the present invention.

As shown in FIG. 1, citrus gourds collected from the tangerine complex processing plant are naturally dried (1) or artificially dried (2) as shown in the primary drying and addition process shown in FIG. After reducing to less than%, the primary dried citrus fruit is transferred to the storage bay (3) and collected, and then sawdust, starch, rice husk, rice straw, etc. Is added as needed. Citrus gourd itself does not have any problem in molding due to its high sugar content, but additives are added only when necessary to reduce moisture and maintain molding.

As shown in FIG. 1, the extrusion process is manufactured in the form of fuel while citrus flakes having 50-60% of moisture from the mixer 4 pass through the extruder 5. Heater (6) can be attached to help heat the molding and reduce moisture. Extruder pressure is generally required more than 800kg pressure per square centimeter, depending on the shape of the extruder inlet Can be produced. Citrus foil fuel produced by passing through the extruder (5) is shaped and cut to a certain size while passing through the cutter (7).

Citrus foil fuel that is molded is about 40% or less of moisture and undergoes the secondary drying process shown in FIG. 1, which may be dried in a natural state, but requires a lot of drying time. To prevent spoilage of the product within a short time, dry it to less than 10% moisture.

Fuel dried from the secondary drying system is commercialized in packaging and can be shipped.

It can be used as an alternative fuel for winter heating of facility-cultivated farmers and as an alternative fuel for industries that need a heat source.
