Description

 Method for preparing green energy fuel from agricultural waste mixed sludge  

The invention relates to a technical field related to renewable energy, in particular to a method for preparing green energy fuel by converting agricultural waste and sludge into gold as an agricultural waste mixed sludge.

According to the agricultural waste, it refers to lignocellulosic or flammable plants, the space pack (bottle) fillings discarded by the peasant farmers, the branches and leaves after greening and pruning, the broken branches and residual wood after the disaster, and the corners of the wood factory Materials, wood chips, rice after harvest, rice straw, corn stalks, peanut shells, flower hibiscus, and sorghum slag.

Among them, the space bag (bottle) used in the cultivation of crops such as Flammulina or mushroom, is a mature agricultural production technology, and is the mainstream way of planting today. However, the use of space bags (bottles) is one-off and cannot be reused or recycled for use in space bags (bottles), resulting in a large number of space bags (bottles) that must be discarded each year to form agricultural waste.

In addition, agricultural waste is large and seasonal and cannot be disposed of by incineration or landfill. The best known method is to recycle compost, but composting requires a long period of biological reaction to generate, resulting in a lack of land, equipment rotation rate and high processing costs.

In addition, a large amount of carbon dioxide and biogas will be produced during the composting process and released into the ambient atmosphere. Generally speaking, carbon dioxide accounts for more than 40% of the original material volume, and about one ton of agricultural waste will yield 0.73 tons during the composting process. Two gasified carbon. The greenhouse effect of biogas is 300 times that of carbon dioxide.

In addition, there will be production of industrial wastewater in the manufacturing process, and these wastewaters must be disposed of by the wastewater treatment plant before they can be discharged. In the process of treating sewage, the sewage treatment plant will produce a certain volume of sludge, which also causes troubles in subsequent treatment.

At present, the treatment of sludge is a control project, which is mainly used as a step brick, a reclamation block or a controlled low-intensity backfill (CLSM) to digest the sludge produced by the sewage plant, but the above practices must be carried out by the competent authority. Approved.

In view of the above problems and deficiencies of the prior art, the main object of the present invention is to provide a method for preparing green energy fuel by mixing waste sludge of agricultural waste, and recycling the sludge of agricultural waste and sewage plant of the mushroom farmer, It is used as a green energy fuel, and the residue after combustion can be recycled as a green energy nutrient to overcome the above-mentioned deficiency.

Another object of the present invention is to recycle other lignocellulosic materials, flammable plants or similar agricultural waste; for example, greening and trimming branches (leaves), broken branches after the disaster, residual wood, and wood factory output Bottom, wood chips, rice, rice straw, cornstalk, peanut shell, flower hibiscus, and sorghum slag after harvest.

According to the above object of the present invention, a method for preparing green energy fuel from agricultural waste mixed sludge is proposed, which is used for recycling agricultural waste and commercial sludge. First, take an agricultural waste and pulverize it into a first mixture of less than 50 mesh, and then mix the first mixture with the sludge in a ratio of 7:3 (±10%) and pulverize into a second mixture of less than 80 mesh. Then, the second mixture is dried to one of the ingots having a water content of 20% or less, and then the ingot is pressed into a green energy fuel ingot having a water content of 10% or less. By the above method, the agricultural waste and the commercial sludge can be recovered, and the green energy fuel can be used as a combustion machine to reduce the lack of pollution of the heavy oil used in the combustion machine, and the progress of turning waste into gold can be achieved.

Hereinafter, the method for preparing the green energy fuel of the agricultural waste mixed sludge of the present invention will be further described with reference to the related drawings. In order to facilitate the understanding of the embodiments of the present invention, the same components are denoted by the same reference numerals.

Referring to Figure 1, the method for preparing the green fuel comprises the following steps:

Step 100: Take an agricultural waste and pulverize it into one of the first mixes of less than 50 mesh. The so-called agricultural waste includes (but is not limited to) lignocellulosic or flammable plants, space pack (bottle) fillings discarded by the peasant farmers, greening and trimming branches (leaves), broken branches after the disaster, residual wood, wood factory Produced under the corners, wood chips, rice after harvest, rice straw, corn stalks, peanut shells, flower hibiscus, and sorghum slag. The agricultural waste is put into a pulverizer for pulverization to obtain a first mixture of less than 50 mesh. When implemented, the agricultural waste is preferably less than 30% moisture content.

Step 200: Mixing the first mixture with a sludge in a ratio of 7:3 (±10%) and pulverizing into a second mixture of less than 80 mesh. The first mixture is mixed with the sludge in proportion and put into a pulverizer for pulverization to obtain a second mixture of less than 80 mesh. In the implementation, the ratio of the first mixture to the sludge is adjusted according to the demand of the calorific value card, and the moisture content of the sludge to be used is preferably less than 30%, and the sludge refers to the use of the EPA. Biological sludge produced by biological treatment procedures or "organic sludge" containing more than 30% of volatile (vs) solids (waste code D-0901). Or chemical sludge produced by physical and chemical treatment procedures or "inorganic sludge" containing more than 30% of volatile (vs) solids (waste code D-0902).

Step 300: Temporarily store the second mixture in the storage tank (tank). Save the second mix by temporarily storing it in the storage tank (slot) to cushion the market and capacity needs. This step can be optionally omitted when implemented.

Step 400: Drying the second mixture into an ingot having a moisture content of 20% or less. The second mixture is dried by a dryer to obtain an ingot having a moisture content of 20% or less.

Step 500: Temporarily storing the ingot in the storage cylinder. Store ingots by temporarily storing them in a storage tank to cushion market and capacity needs. This step can be optionally omitted when implemented.

Step 600: The ingot is pressed into a green energy fuel ingot having a moisture content of 10% or less. The ingot is pressed into a preset shape and a green energy fuel ingot having a moisture content of 10% or less by an extrusion apparatus. At this point, the green energy fuel ingot can be directly put into the burner as a green energy fuel. During the process of burning the green energy fuel ingot at high temperature, the sludge in the green energy fuel ingot is converted into hydrocarbons by the high temperature to form a good auxiliary fuel, which contributes to the improvement of the combustion heat value, plus green The flammability of the first blend (lignocellulosic or flammable plant) in the fuel ingot can produce a calorific value above 4000 calories. And after the combustion is complete, the residue ash is about 5-10% of the total volume, and is rich in nitrogen, phosphorus, potassium, and trace elements. It can also be used as a soil conditioner and fertilizer to achieve complete reuse after combustion. Progressive benefits. Because the residue can be directly used as a soil conditioner and fertilizer, there is no need to go through the composting process, so there is no carbon dioxide and biogas output.

Step 700: Temporarily store the green energy fuel ingot in the storage cylinder. Save green energy fuel ingots by temporarily storing them in a storage tank to cushion market and capacity needs. This step can be optionally omitted when implemented.

Step 800: Bagging the green fuel ingot. The green fuel ingots are packaged according to a certain weight through a packaging machine for subsequent transportation, marketing, storage and use.
