Embodiment 1

[0034] Such as figure 1 Shown, the present invention provides a kind of domestic garbage pyrolysis treatment process, comprises the following steps:

[0035] S101: Domestic waste is processed by bag breaking, magnetic separation, and eddy current separation to obtain magnetic materials, waste batteries, metal substances, and organic waste.

[0036] In this embodiment, a drum bag breaking machine is used to break bags. The bag breaking is mainly used to tear the garbage bags used by the environmental protection department to collect domestic garbage, so that domestic garbage can be scattered from the garbage bags; magnetic separation is used to select domestic garbage The magnetic materials and waste batteries in the magnetic separation, and the domestic garbage after magnetic separation are then sorted by eddy current to separate metal substances, such as non-ferrous metal copper and aluminum. Metals such as copper and aluminum will become catalysts for the formation of dioxi...

Abstract

The invention relates to the field of garbage treatment, and particularly discloses a household garbage cracking treatment process which includes the steps: performing bag breaking, magnetic separation and vortex separation treatment on household garbage, drying obtained organic garbage to obtain water vapor and dry materials, performing catalytic cracking treatment on the dry materials at the temperature ranging from 450 DEG C to 600 DEG C to obtain high-temperature oil gas and carbon black, and condensing the high-temperature oil gas to the temperature of 60 DEG C or less by the aid of a condensation system to obtain liquid oil products and combustible gas without being condensed; purifying the combustible gas without being condensed by the aid of a gas cleaning system, and combusting the purified combustible gas to obtain high-temperature flue gas. The high-temperature flue gas is used for providing heat energy for drying treatment and / or catalytic cracking treatment. According to the household garbage cracking treatment process, the household garbage is converted into the carbon black, the liquid oil products and the combustible gas in a catalytic cracking manner and thoroughly converted into recycling materials, and harmless treatment of the household garbage is achieved.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of garbage treatment, in particular to a domestic garbage cracking treatment process. [0003] 【Background technique】 [0004] With the development of the economy and the improvement of people's living standards, the output of domestic waste is also increasing. At present, domestic mainstream domestic waste disposal methods are landfill, incineration power generation and diversified treatment. The landfill method not only occupies a large amount of land resources, but also causes serious secondary pollution to the land and groundwater; due to the poor classification effect of domestic waste, the calorific value of the material used for incineration for power generation is too low, the power generation efficiency is low, and the dioxin produced by incineration Serious air pollution poses a threat to people's life and health; diversified treatment is to sort domestic waste and then process various items, but th...
