Embodiment 1

[0030] Making batches of 5m with Fe material 3 3.5t of livestock manure with a moisture content of 80-85% and 0.5-1t of paper municipal waste (MSW) were put into the reactor as soon as possible, and the input port at the upper part of the reactor was closed. Simultaneously with the completion of the feeding, livestock manure and municipal waste were mixed, and steam at a temperature of 210° C. was supplied so that the internal pressure of the reactor was 23 atm. At this time, the injected saturated steam or superheated steam reaches the reaction conditions in about 3 to 5 minutes in the steam supply dedicated boiler in the upper part of the reactor prepared in advance, and the supply of steam is interrupted. Stirring was performed at a speed of 10 to 15 rpm so that a physicochemical reaction between the supplied water vapor and the target waste would occur. During the progress of the reaction, saturated steam or superheated steam was intermittently supplied to maintain the at...

Abstract

The present invention relates to an environmentally friendly and high efficiency solid fuel production method using high-water-content organic waste, and, more specifically, relates to a solid fuel production method using high-water-content organic waste, the method comprising: (a) a waste mixing step in which high-water-content organic waste and municipal waste are introduced into a Fe-based reactor and mixed; (b) a hydrolysis step in which high temperature steam is added to the reactor and the mixture of organic waste and municipal waste is placed under pressure and is then stirred in the pressurised state so as to hydrolyse the mixture; (c) a pressure-reducing step in which the steam in the reactor is discharged and the inside of the reactor is rapidly reduced in pressure and left to stand in such a way as to give the organic waste from step (b) a low molecular weight or in such a way as to enlarge the specific surface area of the municipal waste from step (b) and thereby break apart same; (d) a vacuum or differential pressure step in which the reactor is placed under vacuum or differential pressure, and the water content of the reaction product from step (c) is removed; and (e) a solid-fuel forming step in which the reaction product from step (d) is subjected to natural drying and compression moulding so as to produce a solid fuel having a water content of between 10 and 20%.

Description

technical field [0001] The present invention relates to a method for producing solid raw materials from organic wastes with high water content in an environmentally friendly and efficient manner, and a cogeneration system utilizing the method, which significantly reduces malodor. Background technique [0002] Use technologies such as incineration, fermentation, direct and indirect drying to treat organic wastes such as organic sludge and livestock manure. However, in the case of incineration, harmful substances such as dioxins are produced, a large amount of external energy is required, and the installation cost is high, so there is a disadvantage that it is not economical. In addition, when direct and indirect drying is performed, a considerable amount of energy is required to reduce the moisture content of 80% to 15%, and there is a problem that serious odor is generated in the drying process and the dried solid fuel. In addition, in the case of fermentation, the generati...
