Description

METHODS FOR MANUFACTURING FUEL BY USING FOODSTUFFS GABAGE AND ANIMAL SEWAGE}

The present invention relates to a method for producing fuel coal using food waste and animal waste, and more particularly, to a fuel production method using food waste and animal waste produced by mixing animal waste with food waste and waste wood.

Manure refers to feces such as feces excreted from the digestive system and urine discharged from the urinary system.

Carbohydrates, fats, and proteins except for moisture in the bunyu are various infectious diseases and parasitic eggs, and their treatment is important for national health.

In particular, the method of treating livestock manure, which is the manure of livestock, was not easy because of its large facility and the burden of installation was large.

On the other hand, the domestic food and food industry in the domestic food waste is a massive amount of about 4.1 million barrels per year, the country spends a lot of money for the disposal of food waste poured out every year.

Conventional countermeasures to solve such food wastes have been recycled using wastes as fertilizers, feed for livestock, and landfills or incinerators.

This recycling method is insignificant, sharing only a small fraction of the total food waste disposal, indicating that the rest of the waste has been disposed of in landfill or incineration.

Landfill or incineration treatments have started to lead to secondary environmental pollution, which is a representative example of soil pollution from landfills and air pollution from incineration.

As a result, manure and food waste cause overall problems due to environmental pollution that contaminates soil and air.

In addition, although manure and food waste are treated in a variety of ways, there is a problem that a lot of costs are consumed to be processed.

Figure 2 is a conceptual diagram showing each step of the fuel manufacturing method using food waste and nutrient according to an embodiment.

Referring to FIG. 2 in parallel, referring to FIG. 1, there is a drying step (S100) for removing moisture and drying water by heating the shaft portion 10 and the food sludge 30.

Then, the grinding step (S200) for mixing and grinding the crushed wood (10) and the food waste sludge 30 in the drying step (S100) by mixing the waste wood (50).

Subsequently, while stirring the mixture 100 mixed with the clay 70 and the charcoal 90 as a binder in the crushed powder 10, the food sludge 30, the waste wood 50 through the grinding step (S200). Secondary drying has a dry mixing step (S300).

In addition, it comprises a molding step (S400) for compressing and solidifying the mixture 100 made through the dry mixing step (S300) to the press (110).

Drying step ( S100 )

In the drying step (S100), by heating the shaft portion 10 and the food sludge 30 to a temperature of 80 to 200 ℃.

Here, the shaft portion 10 and the food sludge 30 enter the drying rack 110 to be dried.

The shaft portion 10 and the food sludge 30 to be dried in the drying table 110, the drying of the shaft portion 10 and the food sludge 30 when the temperature inside the drying table 110 is less than 80 ℃. It will not work smoothly.

In addition, when the temperature inside the drying rack 110 exceeds 200 ° C, the condensed powder 10 and the food sludge 30 are dried, but the condensed powder 10 and the food sludge 30 are excessively heated. Thus partially carbonizing can proceed.

As such, the shaft portion 10 and the food sludge 30 that have passed through the drying step S100 may have a water content of 15 to 28%.

As a result, in the drying step (S100), the nutrient powder 10 and the food sludge 30 is dried primarily while adjusting so as not to be partially carbonized, and the second nutrient powder 10 while being dried twice again from the following. And the water content of the food sludge 30 is gradually minimized.

In particular, in the drying rack 110 performing the drying step (S100), the shaft portion 10 and the food sludge 30 is dried and at the same time deodorizing operation is made.

Grinding step ( S200 )

In the crushing step (S200), through the drying table 110 to perform the process of grinding the shaft portion 10 and the food sludge 30 dried so that the water content is 15 ~ 28%.

At this time, the pulverized powder 10 and the food sludge 30 is entered into a grinder 120 for grinding, and the waste wood 50, which is used wood, is additionally entered into the grinder 120 to simultaneously grind work. Will perform.

Here, it is preferable that the shaft portion 10, the food sludge 30, and the waste wood 50 are pulverized to 0.5 to 10 mm.

And, when the shaft portion 10 and the food sludge 30 and the waste wood 50 is crushed to a size exceeding 10mm, it is that the shaft powder 10 and the food sludge 30 and the waste wood 50 are mixed with each other It does not work smoothly.

In addition, the shaft portion 10 and the food sludge 30 and the waste wood 50 is more than 0.5mm, while maintaining a constant size, it is possible to be uniformly heated and burned at the same time in the future complete state of fuel. .

For example, the shaft portion 10, the food sludge 30 and the waste wood 50 are crushed at intervals of 0.5 to 10 mm while being transported while being supported on a roller (not shown) having a width of 0.5 to 10 mm. It is preferable to be.

As a result, the shaft portion 10, the food sludge 30 and the waste wood 50 have a horizontal and vertical size of 0.5 to 10 mm, respectively.

Dry mixing step ( S300 )

The dry mixing step (S300), the mixed clay (70) and charcoal (90) as a binder in the crushed powder (10), food sludge (30), waste wood (50) crushed through the grinding step (S200) Secondly drying the mixture 100 while stirring.

Thus, the mixture 100, which is mixed through stirring and drying through the dry mixing step (S300), is mixed with each other and dried at the same time, so that the water content becomes 1 to 5%.

When the water content of the mixture 100 is 1 to 5%, the calorific value is 4000 to 5200 kW / kg.

At this time, the mixture 100, by weight to 100% by weight in total, condensation: 25 to 35%, food sludge: 25 to 35%, waste wood: 10 to 20%, charcoal: 10 to 20% and the remaining clay It is composed of other unavoidable impurities, including.

Here, the food sludge 30 and the shaft portion 10, the fat is contained in the nature, as the fat burns as the burning ash hardens to maintain a continuous calorific value, the waste wood (50) and charcoal (90) is continuous It helps to maintain the calorific value.

In addition, the portion of the mixture 100, the constituents 10 and the food sludge 30, the waste wood 50 and the charcoal 90, the parts that are not closely compressed to each other when mixed with each other, the clay 70 By the addition, the mixture 100 can be pressed closely to each other.

Molding step ( S400 )

In the molding step (S400), it is to perform the operation of solidifying by compressing the mixture 100 made through the dry mixing step (S300) with a compression press 140.

Here, the mixture 100 is pressurized through the compression press 140 so that the mixture 100 in the form required by the user is molded into the solidified fuel 200.

At this time, in the forming step (S400), it is natural that the fuel 200 can be molded in various forms.

As a result, the fuel 200 has a water content (%) of 1 to 5%, and the calorific value is 4000 to 5200 Pa / kg.

Example

Hereinafter, the configuration and operation of the present invention through the preferred embodiment of the present invention will be described in more detail.

However, this is presented as a preferred example of the present invention, it should not be construed that the present invention is limited by this in any sense.

Details that are not described herein will be omitted since those skilled in the art can sufficiently infer technically.

Table 1 shows that the fuel 200, which is a preferred invention material of the present invention, includes the shaft fraction 10, the food sludge 30, the waste wood 50, and the Water content (%) of the mixture having different mixing ratios, while forming the clay 70, the charcoal 90, and the mixture 100 composed of other unavoidable impurities, so that each material has a different mixing ratio. ) And the calorific value (kV / kg) were measured.

Next, in Table 1, the fuel 200 according to the mixing ratio of the shaft portion 10, the food sludge 30, the waste wood 50, the clay 70, and the charcoal 90 The change in moisture content (%) and calorific value (kPa / kg) can be seen.

Example Shaft fraction (%) prog
