Embodiment Construction

[0023] Below in conjunction with specific examples, the present invention is further described, and the following implementations are illustrative, not restrictive, and the protection scope of the present invention cannot be limited by the following examples.

[0024] A comprehensive treatment method for recycling municipal solid waste, the steps of which are:

[0025] (1) Garbage enters the sorting machine for bag breaking, crushing, screening, air selection, and is separated into combustible and non-combustible garbage.

[0026] (2) Non-combustible waste is mainly stones and construction waste, which can be used to make bricks or directly landfill; while small-particle non-combustible waste is mainly slag, soil and kitchen waste, which have a high organic content and can be used for composting It can be used as green fertilizer or replace part of guest soil or directly landfill. .

[0027] (3) The main components of combustible garbage are plastic, fiber, paper, wood debri...

Abstract

The invention relates to a method for sorting and recycling municipal solid waste. The municipal solid waste can be sorted into two types, namely, combustible wastes and incombustible wastes. The combustible waste cracking treatment is as follows: directly introducing a cracking gas to a rectifying tower to separate to obtain aromatic hydrocarbon, oil, asphalt and the like; and sending difficultly-condensed gas to a cracking device as cracking energy, wherein the building garage in the incombustible waste can be used for manufacturing bricks or can be buried directly; and the crushed and separated substances such as kitchen garbage and the like can be used as compost or buried directly, therefore, the reduction, harmlessness and recycling of garbage treatment can be achieved. With the adoption of the treatment method, not only the oil and energy needed by cracking can be obtained from the garbage, but also the high-temperature cracking tail gas can be used for refining oil products after passing through steam produced by a residual heat boiler, thereby the energy consumption can be satisfied during the garbage recycling in a maximum manner.

Description

technical field [0001] The invention relates to a domestic waste treatment technology, in particular to a pyrolysis resource treatment method for combustible waste sorted from domestic waste. Background technique [0002] Urban land resources are very precious, it will become more and more difficult to choose a landfill site for domestic waste, and the cost of landfill disposal will become higher and higher. Incineration treatment has gradually developed into an important means of disposal of domestic waste. The main reason for the use of incineration to dispose of domestic waste is that the combustibles in the waste have increased significantly, especially paper and plastic. The development of municipal waste incineration has promoted the improvement of incineration technology. The new garbage incinerator has stable burning, thorough garbage burning and good heat recovery performance. [0003] In the process of garbage incineration, a large amount of flue gas is emitted, ...
