Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Refer to Figure 1, the flow chart of a typical production method of waste-derived fuels currently on the market. In the process of producing RDF, the raw waste is firstly pretreated010 to remove the bulky components011, and the remaining waste is crushed for the first time012 and dried by drying equipment013 , use magnetic separation equipment to perform magnetic separation 014 on the garbage, recover metal 015 in the garbage, pass the remaining part through the winnowing 016 system to screen combustible 018 and non-combustible 017, and landfill the non-combustible 017 019 treatment, the combustibles 018 are sent to the secondary crushing 020 system for fine crushing again, the processed garbage is added to the additive 021 for garbage forming 022 treatment, cooling unit 023 for cooling treatment, and finally sieving 024 to filter the qualified p...

Abstract

An energy supplying method and an energy balancing-allocating method for producing refuse derived fuel are provided, wherein, the energy supplying method for producing refuse derived fuel comprises: firstly, crude refuse is separated according to different components; secondly, according to separation results, the refuse is fed into corresponding systems for treatment respectively; finally, the energy generated by a refuse fermenting system is supplied to a refuse derived fuel manufacturing system for use. The energy balancing-allocating method is that: according to the surplus conditions of a refuse derived fuel factory in energy use, partial organic refuse originally used for the fermenting system is also used as the raw materials in the production of refuse derived fuel, so as to realize the supply of the fermenting system and the energy balance needed in the production process of refuse derived fuel. The present invention has the advantages that: RDF production cost is reduced; RDF heat value is improved; the amount of biodegradable component used for fermentation can be flexibly adjusted according to the concrete conditions of energy balance.

Description

【Technical field】 [0001] The invention relates to an energy supply method and an energy allocation method in the process of processing garbage, in particular to an energy self-supply method and an energy balance allocation method for producing garbage-derived fuels. 【Background technique】 [0002] RDF, the abbreviation of Refuse Derived Fuel, refers to the derived fuel made from garbage and waste. Compared with the traditional domestic waste incineration technology, it has the advantages of easy transportation and storage of raw materials, high calorific value, stable combustion, and low secondary pollutants. It has good development prospects. municipal solid waste disposal methods. [0003] The RDF production method currently used in China is developed by applying the technology of foreign municipal solid waste. The waste sorting system in foreign RDF production methods includes pretreatment of waste, crushing, drying, magnetic separation, air separation, and then all com...
