Embodiment 1

[0060] A kind of comprehensive processing method of organic waste, it comprises the following steps:

[0061] ①In the pyrolysis unit with a temperature of 300°C in a nitrogen atmosphere, the waste plastics are pyrolyzed for 2 hours; the pyrolysis products are obtained;

[0062] ②The pyrolysis product is passed into a thermal catalytic unit with a temperature of 800°C. The thermal catalytic unit is equipped with a Co-based catalyst with a particle size of about 10 nanometers, and the pyrolysis product is subjected to thermal catalytic treatment for 5 hours to obtain carbon nanotubes and hydrogen.

[0063] ③ The gas exhausted by the thermal catalytic unit is separated and purified by the gas separation unit, and hydrogen is recovered in the gas collection unit.

Embodiment 2

[0065] A kind of comprehensive processing method of organic waste, it comprises the following steps:

[0066] ①In the pyrolysis unit with a temperature of 400°C in a nitrogen atmosphere, the waste plastics are pyrolyzed for 3 hours; the pyrolysis products are obtained;

[0067] ②The pyrolysis product is passed into a thermal catalytic unit with a temperature of 750°C. A copper foil catalyst is installed in the thermal catalytic unit, and the pyrolysis product is subjected to thermal catalytic treatment for 5 hours to obtain graphene and hydrogen.

[0068] ③ The gas exhausted by the thermal catalytic unit is separated and purified by the gas separation unit, and hydrogen is recovered in the gas collection unit.

Abstract

The invention belongs to the technical field of waste treatment, and particularly relates to a comprehensive treatment method for organic waste. The method comprises the following steps: cracking organic waste to obtain a cracking product; and under the action of a metal catalyst, carrying out thermal catalytic treatment on the cracking product to obtain a nano carbon material and hydrogen. According to the comprehensive treatment method for organic waste, the organic waste is adopted as a raw material, through cracking treatment and thermal catalytic treatment, the carbon element in the organic waste is converted into the nano carbon material, the hydrogen element is purified and enriched in the form of hydrogen to obtain high-purity hydrogen energy, and the treatment method of the organic waste can realize zero carbon emission, zero pollution and high recycling rate, reduce environmental pollution and improve social benefits.

Description

technical field [0001] The application belongs to the technical field of waste treatment, and in particular relates to a comprehensive treatment method for organic waste and a comprehensive treatment system for organic waste. Background technique [0002] With the acceleration of industrialization and the rapid development of urbanization, the waste organic matter produced has increased rapidly. General waste organic matter is divided into: plastic, rubber, fiber and other solid waste, waste engine oil, civil oil and other liquid waste, industrial waste gas, civil waste gas and other gas waste. At present, the disposal of solid waste such as waste plastics and waste rubber is mainly landfill and incineration. Since waste plastics and rubber cannot be naturally degraded into the natural ecological cycle like natural polymers, they are difficult to degrade after being landfilled, and it is easy to form white pollution into the soil and ocean; while incineration will form a la...
