Description

technical field

[0001] The invention relates to the technical field of urban garbage treatment, specifically a method for preparing derivative fuel RDF, bio-organic fertilizer and inorganic building materials at one time by using high-humidity mixed urban garbage as raw materials. Background technique

[0002] Among the traditional waste disposal methods, the sanitary landfill method: due to the large area, high processing costs, and waste of a lot of land resources, the applicable value gradually decreases; the composting method: due to incomplete utilization of organic matter, complex fertilizer components, and reduced Factors such as smaller size will be gradually eliminated; garbage incineration will become the mainstream of harmless treatment of municipal solid waste because of its many unique advantages. The main manifestations are as follows: 1. After the garbage is incinerated, the pathogens in the garbage are completely eliminated, and the harmful gas and smoke gene...

Examples

Embodiment 1

[0090] Embodiment 1: the method for preparing derivative fuel RDF, bio-organic fertilizer and inorganic building materials with rubbish as raw material, comprises the following steps:

[0091] 1. Garbage sorting and crushing: Effective mechanized sorting and crushing of high-humidity mixed urban waste, ensuring bag breaking rate ≥ 95%, output block size ≤ 100mm, automatic sorting out bricks, rubble, metal, batteries Hard materials such as leather goods, clothes and other large items, among which leather goods, clothes and other large items are returned to the system for secondary crushing after large-scale crushing;

[0092] 2. Drum screening: It is the process of screening the remaining broken garbage with a water content of 50% after sorting and crushing in a special drum sieve. It classifies the garbage into two parts: the oversize and the undersize. The typical composition of the upper object is:

[0093] The typical ingredient list (table four, unit: weight %) of the sie...
