Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. This article takes the pyrolysis process of waste rubber as an example to describe the waste plastic pyrolysis treatment method of the present invention. The products obtained from the waste rubber pyrolysis process include carbon black, steel wire, fuel oil, and gas. Of course, this method can also be applied to pyrolysis processes such as plastic waste, waste tires, medical waste, and sludge. The pyrolysis reaction chamber of the present invention can be selected from one of rotary kiln type and fluidized bed type.

[0016] refer to figure 1 As shown, in the specific embodiment of the present invention, the waste plastics pyrolysis treatment method mainly includes the following steps:

[0017] Step 1 101. Crushing the polymeric organic solid waste (waste rubber) to be pyrolyzed; wherein the size (diagonal line) of the crushed rubber pa...

Abstract

The invention relates to a thermal pyrolysis treatment method for organic wastes, which includes the following steps: (1) crushing high-molecular solid organic wastes; (2) melting the crushed high-molecular solid organic wastes at certain temperature to obtain a liquid to-be-pyrolyzed material; and (3) feeding the liquid to-be-pyrolyzed material to a pyrolytic reaction chamber and moving the material from a feeding end of the pyrolytic reaction chamber to a discharge end of the pyrolytic reaction chamber, so that the material is continuously subjected to a pyrolysis reaction during the moving process for converting the liquid to-be-pyrolyzed material into a gas-phase product and a solid-phase product through the pyrolysis reaction, wherein the pyrolysis reaction is 370-410 DEG C in temperature range and is carried out without a catalyst. The pyrolysis reaction effectively improves device safety performance and service life and reduces production cost on the basis of ensuring pyrolysis reaction efficiency and process yield.

Description

technical field [0001] The invention relates to the field of polymer organic solid waste treatment, in particular to a non-catalytic low-temperature pyrolysis treatment method for polymer organic solid waste. Background technique [0002] At present, with the continuous consumption of limited resources on the earth, the topic of environmental protection and energy saving has increasingly become the focus of people's research. The rapid development of modern industry has resulted in the output of a large amount of waste organic materials, including waste tires, waste rubber, waste plastics and other organic waste. Random disposal or unreasonable treatment will inevitably damage the natural ecological environment. Therefore, how to treat the above waste organic materials The treatment of environmental protection and resource reuse has become a research topic attracting worldwide attention. [0003] In the existing technology, the most environmentally friendly polymer organic ...
