Problems solved by technology

A device that uses RDR only for physical properties means it suffers from poor sortability due to moisture
In addition, the bio-drying of domestic waste as fuel should pursue conservative bio-energy, but since the drum reactor is still in the composting technology of expanding bio-energy, the device and operation method need to be improved

Embodiment Construction

[0041] Based on the embodiments of the present invention and the accompanying drawings, the present invention will be described in detail as follows.

[0042] Such as figure 1 As shown, the domestic waste treatment device 1 according to the embodiment of the present invention includes: a crushing element 10 , a sorting element 20 , a reaction element 30 , a return element 40 and a regeneration element 50 .

[0043] Here, the domestic garbage in the present invention refers to all garbage left after sorting and recycling or garbage that is not sorted and recycled, and the icon "R" is shown in the accompanying drawings. In addition, the intermediate product in the operation process is also shown as "R", and the return material is shown as "R1". The arrows shown indicate the movement channels of domestic waste.

[0044]The crushing element 10 is a pretreatment device that breaks the bag of domestic garbage R, that is, tears the packaging bag similar to a plastic bag, sorts and ...

Abstract

A municipal solid waste treatment device, according to the present invention, comprises: a crushing unit which tears municipal solid waste and selectively pulverizes organic matter; a selection unit for classifying and selecting the municipal solid waste discharged from the crushing unit; a reaction unit for bio-drying the classified and selected municipal solid waste; a return unit which returns the bio-dried municipal solid waste to the crushing unit so as to increase a selectivity rate; and a recycling unit for recycling the remaining organic matter and combustibles, wherein the crushing unit is a rotary drum-type crusher for naturally and selectively pulverizing only the organic matter without using force, thereby enabling high-purity selection with minimum energy consumption, and the crushing unit adjusts a moisture content by using the organic matter dried in the reaction unit at the rear end part whereby a higher selection efficiency can be obtained, and the reaction unit at the rear end part is a bio-drying device for carrying out a drying process in a short time without using external drying energy.

Description

technical field [0001] The invention relates to a domestic waste treatment device, in particular to a domestic waste treatment device which can improve the treatment efficiency through the pretreatment process of bag breaking and crushing of domestic waste. Background technique [0002] Usually, municipal solid waste (MSW) is disposed of by landfill or incineration. However, in recent years, in order to recycle domestic waste, mechanical biological treatment (Mechanical Biological Treatment, MBT) schemes such as crushing, sorting, aerobic decomposition, and anaerobic energy, etc., which combine mechanization and biological technology, are also widely used. current promotional trends. [0003] At present, the sequence of mechanical and biological treatment of domestic waste is formed by breaking bags, crushing → moisture drying → sorting non-combustible / combustible / organic matter → recycling the sorted combustible and organic matter. Rotary Drum Reactor (RDR) is a pretreatm...
