Definitions
- the present invention relates to an environmentally friendly and high efficiency solid fuel production method using a high-water-content organic waste and a combined heat and power system using the same while noticeably reducing bad smell.
- Organic waste such as sludge, livestock excretions in general is treated using a technology such as incineration, fermentation, direct or indirect drying, etc.
- incineration it produces dioxin and a lot of harmful substance and requires a large amount of externally supplied energy along with increased installation cost, so the above-mentioned incineration has a disadvantage in that it is not economical.
- a large amount of energy is required so as to lower the water content from 80% to 15% in the course of direct or indirect drying, and bad smell generates from solid fuel during the drying process and after the drying process.
- the fermentation it have some problems in that a lot of bad smell generates, and energy efficiency is low, and it takes long time to treat waste water.
- a technology for developing a solid fuel is going on so as to treat high-water-content organic waste into energy source. In this case, it necessarily needs to lower the water content below 15%.
- Such a solid fuel process technology is categorized into drying and carbonization. In terms of the total amount of energy, the drying is most preferred. The bad smell generating in the course of the drying and the bad smell generating in the course of the storing and use of the produced fuel become problematic.
- an environmentally friendly and high efficiency solid fuel production method using a high-water-content organic waste comprising:
- a waste mixing step where a high-water-content organic waste and a municipal solid waste are inputted and mixed in a Fe-based reactor
- a hydrolysis step where a mixture of the organic waste and the municipal solid waste is pressurized by adding high temperature vapor into the reactor and is agitated in the pressurized state for thereby hydrolyzing the mixture
- a depressurization step where the reactor is controlled to remain in normal state after the interior of the reactor is suddenly depressurized by discharging the vapor from the interior of the reactor, and the mixture is crushed by depolymerizing the organic waste treated through the step (b) or by increasing the specific surface area of the municipal solid waste treated through the step (b);
- a vacuum or differential pressure step where water is eliminated from the reactant treated through the step (c) by providing the vacuum or differential pressure condition to the reactor
- a solid fuel preparation step where a solid fuel of which the water content is 10 ⁇ 20% is prepared by naturally drying the reactant treated through the step (d).
- the present invention is characterized in that the solid fuel may be produced by efficiently drying the internal water of the organic waste in such a way to much more effectively degrade the organic matter and bad smell with the aid of the degrading power of vapor radical and the promoted peptone reaction by the Fe reaction catalyst by inputting and mixing high-water-content organic waste and municipal solid waste into a Fe-based reactor and adding high temperature and pressure vapor and in such a way to completely crush and degrade the organic waste based on the sudden depressurization.
- the present invention makes it possible to produce solid fuel within a short time by greatly enhancing the efficiency of drying in such a way that the non-degraded organic waste is depolymerized through the sudden depressurization after high temperature and pressure vapor is inputted and that the specific surface area is increased by expanding the municipal solid waste.
- the solid fuel produced according to the present invention may be provided as a good energy source which may substitute fossil energy thanks to its high calorific power. So, it is possible to efficiently generate electricity based on the combined heat and power generator system using the above mentioned energy source.
- FIG. 1 is a view illustrating a treatment system of a high-water-content organic waste according to the present invention.
- FIG. 2 is an ion product change and permittivity change curve of water.
- the present invention is directed to an environmentally friendly and high efficiency solid fuel production method using a high-water-content organic waste which makes it possible to efficiently dry the internal water of the organic waste in such a way to much more effectively degrade the organic matter and bad smell with the aid of the degrading power of vapor radical and the promoted peptone reaction by the Fe reaction catalyst by inputting and mixing high-water-content organic waste and municipal solid waste into a Fe-based reactor and adding high temperature and pressure vapor and in such a way to completely crush and degrade the organic waste based on the sudden depressurization.
- the present invention is directed to a solid fuel production method using a high-water-content organic waste, which includes (a) a waste mixing step where a high-water-content organic waste and a municipal solid waste are inputted and mixed in a Fe-based reactor; (b) a hydrolysis step where a mixture of the organic waste and the municipal solid waste is pressurized by adding high temperature vapor into the reactor and is agitated in the pressurized state for thereby hydrolyzing the mixture; (c) a depressurization step where the reactor is controlled to remain in normal state after the interior of the reactor is suddenly depressurized by discharging the vapor from the interior of the reactor, and the mixture is crushed by depolymerizing the organic waste treated through the step (b) or by increasing the specific surface area of the municipal solid waste treated through the step (b); (d) a vacuum or differential pressure step where water is eliminated from the reactant treated through the step (c) by providing the vacuum or differential pressure condition to the reactor; and (e) a solid fuel preparation step where a solid fuel
- the step (a) is a step where high-water-content organic waste and municipal solid waste are inputted and mixed in a Fe-based reactor.
- the high-water-content organic waste is one or at least one selected from the group consisting of livestock excretions, sewage sludgy, and food waste and contains more than 80% of water content, and the municipal solid waste preferably contains kind of paper and plastics.
- the municipal solid waste containing such paper and plastics each having increased specific surface area reacts while expanding together with the organic waste which was depolymerized by means of the depressurization in the depressurization step, so the drying efficiency may be maximized.
- the plastics-based municipal solid waste which is a kind of a petroleum-based organic substance is contained, it is possible to enhance the low calorific power of the produced solid fuel.
- the municipal solid waste contains 50 ⁇ 55% by weigh of paper, and 40 ⁇ 45% by weight of plastics.
- the high-water-content organic waste and the municipal solid waste are inputted and mixed at a ratio of 3.5 ⁇ 4:0.5 ⁇ 1.
- the high-water-content organic waste and the municipal solid waste are inputted and mixed in the reactor at a filling ratio of 70 ⁇ 90%. Since high temperature and pressure vapor may be supplied from outside the reactor even though the waste, which will be treated, is inputted into the reactor at such high charging rate, and the contact-based reaction with the saturated vapor can be maintained, so that it is possible to enhance the efficiency of reaction in the highest process capacity of the wastes.
- the step (b) is a step where a mixture of the organic waste and the municipal solid waste is pressurized by supplying high temperature of vapor into the reactor, and the mixture is agitated in the pressurized state and is hydrolyzed.
- the substance belonging to the organic waste is degraded and depolymerized by the pressurization, and the bad smell containing sulfuric acid is degraded, so the water content of the organic waste may be greatly lowered thanks to the high temperature while eliminating bad smell.
- the mixture may be agitated and undergo the hydrolysis reaction after the internal pressure of the reactor is made to 20 ⁇ 25 atm by supplying the vapor of 200 ⁇ 250° C. into the reactor.
- the ion product reaction is most active at the temperature of 200 ⁇ 250° C. and shows 1,000 times higher activity as compared with the room temperature. Since the permittivity lowers to 1 ⁇ 3 ⁇ 1 ⁇ 4 as compared with the room temperature, a potential difference occurs between the ions, which would result in increased organic substance degradation performance. If it is below the range of the above temperature and pressure, it is hard to obtain the desired effect, and when it is above the range of the above temperature and pressure, the loss in energy may occur.
- step (b) of the present invention since the supply of the vapor is performed using a boiler which is connected to the reactor, the organic waste in the reactor comes into contact with the vapor from the boiler and physically and chemically reacts for thereby greatly enhancing the efficiency of the reaction without any procedure where the water changes to high temperature water in such a way that it is sprayed while coming into direct contact with the low temperature organic waste.
- the vapor since the vapor is supplied using the externally supplied boiler, any phenomenon where it reacts with high temperature water does not occur, so the reaction may be maintained even when the amount of the waste increases. Therefore, the mixture of the waste, which will be treated, is charged up to 70 ⁇ 90% of the reactor, thus causing a contact-based reaction with the vapor.
- the efficiency of the reaction may be greatly enhanced thanks to the catalyst reaction of Fe, in particular the promoted peptone reaction in the region where the saturated vapor occupies in the reactor, and an organic membrane of 1 ⁇ 2 mm is formed in the inner side of the reactor based on the process and operation of the reactor, so it is possible to prevent any corrosion due to NaCl, etc.
- the step (c) of the present invention is a step where the reactor is controlled to remain in normal state after the pressure inside of the reactor is suddenly depressurized by discharging the vapor from the interior of the reactor, so that the organic waste treated through the step (b) is depolymerized or the specific surface area of the municipal solid waste treated through the step (b) is increased, and the municipal solid waste is crushed, more specifically, the step (c) is a step where the reactant pressurized by high temperature vapor is suddenly depressurized, and the volume of increased, thus depolymerizing the reactant or crushing the reactant.
- the drying time may be shortened because such municipal solid waste is reacted with the water-content organic matter and is dried, thus greatly enhancing the efficiency of the drying.
- the pressure is suddenly depressurized so that the atmosphere may become 0.9 ⁇ 1.1 atm by discharging the vapor inside of the reactor for 10 ⁇ 120 seconds.
- the step (d) of the present invention is a step where the moisture is eliminated from the reactant treated through the step (c) by adopting the vacuum or differential pressure condition to the reactor.
