Embodiment 1

[0037] Grind the pyrolysis carbon slag, take 100g of the ground charcoal powder and test the toluene light transmittance and the 45 micron sieve residue. Grain requirements.

[0038] When the temperature of the 4th wall of the granulator rises to 120°C, start feeding. After the carbon powder is fed from the silo 1 through the star discharge valve 2, the opening of the control valve 2 is 4Hz, and enters the variable diameter feeding screw 3 (the diameter reduction ratio is 0.5), and the compacted carbon powder enters the granulation Machine 4. When there is powder carbon black in the sampling port 5, open the granulation water ball valve 6. By continuously observing the granulation of the carbon black at the sampling port 5, the opening of the granulation water ball valve 6 is reasonably adjusted. When the particle is stable at the size of small grains (about 0.5-2mm), fix the opening of the granulation water valve 6 at this moment.

Abstract

The invention relates to a method for preparing high-quality granulated carbon black from cracked carbon residues, which comprises the following steps: (1) grinding the cracked carbon slag to obtain carbon powder, (2) conveying the obtained carbon powder to a granulation process, (3) granulating, wherein the particle size of the granulated carbon black is controlled between 0.5 mm and 2 mm, and (4) drying granulation moisture in the carbon black until the granulation moisture is less than 2wt%, thereby obtaining the finished product granulation carbon black. Aiming at the unique properties ofthe pyrolysis carbon powder, the pyrolysis carbon black with the same granular performance as commercial carbon black can be obtained by pre-inspecting and controlling the raw materials, improving thefeeding process and adjusting the granulation process parameters, so that reliable and stable granulation can be realized.

Description

technical field [0001] The invention relates to a method for preparing high-quality granulated carbon black from pyrolysis carbon residue, which can realize stable granulation of pyrolysis carbon residue into high-quality pyrolysis carbon black. Background technique [0002] At this stage, with the rapid development of waste tire pyrolysis technology, waste tire pyrolysis enterprises are also showing multi-point flowering, which directly leads to the rapid rise of the price of waste tire raw materials, and the production enterprises are facing the plight of a serious decline in profits. In view of this, the development of high-value cracking products has become the top priority of the industry. [0003] As one of the main products of waste tire pyrolysis, pyrolysis carbon black has a yield of about 35%. However, due to its high ash content and low structure, it is difficult to be directly used as a raw material in the downstream industrial chain, and its value is the lowest....
