Embodiment 1

[0029] Example 1, the present invention provides a dual-wave pyrolysis device for industrial organic waste. The waste tank (1) is connected to the feed port (2), and the feed port (2) is connected to the pyrolysis chamber (4) through a pipeline. The chamber (4) is provided with a screw propeller (3); there are 9 cracking chambers (4), which are arranged in three vertical and three horizontal directions, and the three longitudinally arranged cracking chambers (4) form a group and are connected in series. That is, the discharge port (11) of the upper cracking chamber (4) is connected to the feed port (12) of the lower cracking chamber (4), and a cracking gas outlet (5) is arranged above the cracking chamber (4), and the bottom cracking chamber ( The lower end of 4) is provided with a residue outlet (10); the three groups of cracking chambers are connected in parallel, and the cracking gas outlets (5) of the nine cracking chambers are all connected to the cracking gas collection p...

Embodiment 2

[0035] Embodiment 2, the present invention provides a kind of method of double-wave pyrolysis processing industrial organic waste, comprises the following steps:

[0036] S1 pretreatment, dehydration or crushing of industrial organic waste;

[0037] S2 thermal cracking, the industrial organic waste residue or waste liquid obtained by pretreatment is continuously sent into the cracking chamber of the double wave cracking device through the feed port, and under microwave irradiation, the thermal cracking effect of microwave is used to remove the organic waste in the organic waste Large molecules are split into small organic molecules and polar and non-polar substances, such as H 2 S, CH 4 etc., the cracking temperature can reach 600-800°C;

[0038]S3 catalytic cracking, after thermal cracking, microwave cracking enters the microwave catalytic cracking stage, through the polarization of microwaves, the polar bonds of polar substances are oscillating, twisting, and activated uns...

Abstract

The invention discloses a method for treating industrial organic waste through double-wave cracking, and relates to the technical field of organic waste treatment. Through ultrasonic-assisted microwave thermal cracking, internal bonds of macromolecular organic matters are broken to form micromolecular organic matters, polar and non-polar substances and the like; performing ultrasonic-assisted microwave catalytic cracking to enable the polar bond of the polar substance to be vibrated, twisted and activated to be unstable, and cracking the polar substance. The method has the beneficial effects that the industrial organic waste is subjected to cracking treatment through cooperation of ultrasonic waves and microwaves, the method has the characteristics of being rapid, efficient, low in energy consumption, low in cost, high in resource utilization rate, easy to operate, high in volume reduction rate, capable of remarkably reducing harm caused by the industrial organic waste to the environment and the like, and harmless treatment is truly achieved.

Description

technical field [0001] The invention relates to the technical field of organic waste treatment, in particular to a dual-wave cracking method for treating industrial organic waste. Background technique [0002] Industrial waste refers to substances that pollute the environment, such as rubber tires, that are generated in the production activities of factories and cannot be used at a certain time and place and are discarded. Industrial organic waste refers to industrial waste containing organic components. If waste is not properly treated, long-term stockpiling will not only occupy a large amount of land, but also cause serious pollution to water bodies and the atmosphere. At present, there are three main methods of waste disposal: landfill, incineration and composting. The biggest advantage of the landfill method is that the treatment cost is relatively low, but it takes up a lot of land resources and pollutes the environment; the process of the composting method is difficu...
