Processing system for organic waste

Abstract

The invention relates to a processing system for organic waste. The processing system for organic waste can deal with industrial waster like mud and plastic scraps, and also can stirring municipal waste from household and general public service in a two-wall structural pressure container at high temperature and pressure. After the treatment for recomposing waster by using hydro-thermal reaction under thermal conditions, the treated dry water can be recycled after classification.

Description

Technical field [0001] The present invention relates to an organic waste treatment system, which can undergo hydrothermal reaction under subcritical water conditions, in addition to industrial waste including sludge and waste plastics, but also The general waste generated by households or general businesses is decomposed, etc., and the processed waste can be taken out in a dry state, sorted, and reused. Background technique [0002] In the conventional organic waste treatment system, the wastes to be treated are classified in advance, and the wastes are separately input into treatment devices designed according to the types of the classified wastes for treatment. For example, it is possible to put waste plastics into a special treatment device for plastics, to put rubber waste such as waste tires into a treatment device for rubber, and to put old newspapers or paper scraps into paper. In the processing device, the waste such as kitchen garbage is put into a special processing dev...

Problems solved by technology

[0011] The system disclosed in Patent Document 5 is a system for processing other general materials such as waste in a high-temperature and high-pressure environment so that they can be reused as exothermic moldings. When the pressure-resistant container is opened, the internal gas or vapor is discharged to the outside. Therefore, when pathogenic bacteria, microorganisms, and miscellaneous bacteria, etc. remain, they may be diffused into the atmosphere together. There is still room for improvement in this regard

[0012] In addition, the decomposition treatment method and device disclosed in Patent Document 6 also use hydrothermal reaction to decompose and treat refractory waste at a temperature below the critical pressure. this question

[0013] Moreover, the treatment method of organic waste disclosed in Patent Document 7 is a method of performing oxidation treatment in high-temperature and high-pressure steam set at a temperature above the supercritical temperature of water and below the supercritical pressure. However, due to the set temperature At 500°C or higher, the pressure is relatively high from 5MPa to 22Mpa, so it is difficult to develop a device that can withstand this high temperature and high pressure, and there is also the problem of cost increase

[0014] Moreover, the high-temperature and high-pressure treatment device disclosed in Patent Document 8 is a device that continuously oxidizes organic waste in the state of supercritical water or subcritical water, and the preferred subcritical water treatment condition for the oxidation decomposition reaction is a temperature of 250 ℃ and above, and the treatment pressure is 5-10 MPa, therefore, it is difficult to develop a device for continuous oxidation treatment under this condition, and there is also the problem that the increase is too high

[0015] The inventions disclosed in the above-mentioned Patent Documents 5 to 8 are inventions in which wastes are decomposed by hydrothermal reaction. The steam turns back into water and the treated waste is soaked in water, making it difficult to remove from the device

In addition, in order to reuse the treated waste, it is necessary to re-dry it, so there is a problem that the cost is too high
