Friction-dragging thermal cracking treatment method of household garbage

Abstract

The invention discloses a friction-dragging thermal cracking treatment method of household garbage. The friction-dragging thermal cracking treatment method comprises the following steps of: S1, filling the household garbage into a sealed friction thermal cracking device; S2, carrying out frication dragging on the household garbage through the rotation of a rotor of a rotor friction-dragging unit to generate friction heat and friction dragging force, so that the household garbage is thermally cracked by friction-dragging to obtain a product mixture; S3, carrying out settling treatment on the product mixture for separating out solid product in the product mixture to obtain the solid product; and S4, carrying out gas-liquid separation treatment on the rest of the product mixture to obtain gas substance and water oil liquor. The friction-dragging thermal cracking treatment method of the household garbage is simple to operate, capable of carrying out friction-dragging thermal cracking conversion for converting the household garbage into products including the gas substance, the water oil liquor, the charcoal ash powder and the like for recycling, so that the zero-residue, zero-emission, resource-recycling, energy-resource-recycling and industrial conversion utilization of the garbage is realized, and therefore, the friction-dragging thermal cracking treatment method is environment-friendly.

Description

technical field

[0001] The invention relates to the field of garbage treatment, in particular to a friction-drag thermal cracking treatment method for domestic garbage. Background technique

[0002] With the development of society, the consumption of resources and energy and the waste of domestic waste are increasing year by year, which leads to the shortage of resources and energy, and the infestation of garbage, which seriously affects the harmonious development of society and the ecological environment. Among them, domestic waste mainly includes discarded materials in the process of human activities, mainly paper, plastic, rubber, vegetation, cloth, kitchen waste, leather products, inorganic substances, metals, glass and ceramics. According to statistics, the per capita daily domestic waste is about 0.8-1.4kg, which is a huge amount.

[0003] The existing traditional treatment methods for domestic waste generally include composting, landfilling and incineration. The way...

Examples

Embodiment 1-3

[0038] Randomly take household garbage from the garbage pool, remove glass, metal, pottery and stones therein, put it into a frictional thermal cracking device, and process it through the treatment method of the present invention. The amount of domestic waste converted and products after thermal cracking of each embodiment are shown in Table 1 and Table 2 below.

[0039] Table 1. Raw material weight of each embodiment and products after thermal cracking

[0040]

[0041] Attachment: Conversion amount (kg) = starting material amount (kg) - remaining unconverted material amount (kg).

[0042] In the above examples, the friction thermal cracking device used: diameter 1000mm, length 6000mm; screw in the screw extrusion unit: diameter 990mm, length 2000mm; rotor: diameter 980mm; settler: volume 2.5-4m 3 ;Gas-liquid separator: volume 2.5-4m 3 .

[0043] As can be seen from the data in Table 1 above, the treatment method of the present invention has a good transformation effect...
