Embodiment

[0044] like figure 1 As shown, a kind of waste tire described in the present embodiment prepares the method for industrial carbon black, comprises the following steps:

[0045] Step 1: Send waste tires into a pyrolysis kettle for pyrolysis to obtain oil-gas mixture, furnace exhaust gas, coarse carbon black and steel wire;

[0046] The above-mentioned oil-gas mixture mainly contains light oil gas, heavy oil gas and some tar-like colloidal substances; while the temperature of the furnace exhaust gas coming out of the pyrolysis kettle is 120~300°C, and the exhaust gas mainly contains CO, CO 2 , HC, NOX, water vapor, etc.

[0047] Step 2: Carry out oil and gas separation step, furnace exhaust gas treatment step, crude carbon black purification step and steel wire treatment step respectively. It should be noted that the steps mentioned here are not in sequence;

[0048] The oil-gas separation step is used to separate the oil-gas mixture to obtain non-condensable combustible gas a...

Abstract

The invention discloses a method for preparing industrial carbon black from waste tires. The method comprises the steps as follows: step 1, waste tires are sent into a pyrolysis kettle for pyrolysis,and an oil-gas mixture, combustion chamber waste gas, crude carbon black and steel wires are obtained; step 2, oil-gas separation, combustion chamber waste gas treatment, crude carbon black purification and steel wire treatment are performed, respectively. With the adoption of the method, the utilization value of the waste tires can be increased, waste gas, oil gas and the like produced during pyrolysis of the waste tires can be classified, waste gas can reach the emission standard, environmental pollution can be prevented, classified recovery of the oil gas can be realized, and resource wastecan be reduced greatly.

Description

technical field [0001] The invention belongs to the technical field of waste tire treatment, and in particular relates to a method for preparing industrial carbon black from waste tires. Background technique [0002] As automobiles gradually become the first engine to drive residents' consumption, China is facing serious environmental pollution caused by waste tires. According to relevant reports, China has become the third country after the United States and Japan to produce more than 10 million vehicles per year, and has become a veritable "automotive power". However, with the advent of the automobile age, there are still mountains of waste tires. In highly industrialized countries, due to the rapid increase in awareness of the pollution problems in modern society, people's ideology tends to advocate nature, so waste rubber tires have also become the focus of discussion. [0003] In line with the principles of harmless, reduction and resourceful treatment of waste, more ...
