Waste rubber pyrolysis treatment method

Abstract

The invention discloses a waste rubber pyrolysis treatment method which comprises the following steps: crushing waste rubber into rubber particles; adding the rubber particles, a cooling catalyst, an anti-coking catalystand a heat transfer medium into a pyrolysis reactor, enabling the heated materials to produce pyrolysis mixed gases on the upper part of the reactor, and remaining waste steel wires and carbon black at the bottom of the reactor; delivering the pyrolysis mixed gases to a cooling tower so as to obtain mixed oil gas; and filling the mixed oil gas into a gas-liquid separation tank, outputting pyrolysis oil into a liquid storage tank from the tank bottom of the gas-liquid separation tank, and outputting the pyrolysis gas into a gas storage tank from the top of the gas-liquid separation tank. According to the method disclosed by the invention, continuous waste rubber pyrolysis can be well realized, the rubber is prevented from coking in the pyrolysis process, the environmental pollution caused by the waste rubber is avoided, and the resources are effectively recycled.

Description

technical field [0001] The invention relates to a waste rubber pyrolysis treatment method. Background technique [0002] The heat transfer performance of waste rubber is poor, and it will be heated unevenly during the pyrolysis process. When the temperature difference of the material inside the reactor can reach more than 400°C, the temperature of the material near the inner wall of the reactor sometimes even reaches about 900°C. It is easy to form coke and carbon deposits under the environment, resulting in the failure of the pyrolysis process to proceed normally, and the need to stop for cleaning, which seriously affects the orderly production. Contents of the invention [0003] The invention provides a waste rubber pyrolysis treatment method, which can better realize continuous pyrolysis of waste rubber, prevent coking in the pyrolysis process, avoid environmental pollution caused by waste rubber, and realize effective recycling of resources. [0004] In order to solve...

[0002] The heat transfer performance of waste rubber is poor, and it will be heated unevenly during the pyrolysis process. When the temperature difference of the material inside the reactor can reach more than 400°C, the temperature of the material near the inner wall of the reactor sometimes even reaches about 900°C. It is very easy to form coke and carbon deposits under the environment, resulting in the failure of the pyrolysis process to proceed normally, and it must be stopped for cleaning, which seriously affects the orderly production.
