Problems solved by technology

However, at present, the semi-coke after coal separation and conversion is mainly cooled by dry method, which requires a large investment in equipment. After the dry cooling of the semi-coke, the semi-coke needs to be further crushed to reduce the volume of the semi-coke and then mixed with water to form Pulp, the pulping speed is slow and the operation process is long, which is not conducive to the large-scale pulping of semi-coke

Abstract

The invention relates to the technical field of water-coke slurry and in particular relates to a preparation method of water-coke slurry. Compared with dry-method cooling in the prior art and compared with slurry forming carried out by mechanical crushing and mechanical stirring, the preparation method is simple and has a relatively rapid slurry forming speed so that the preparation method is suitable for large-scale slurry forming of semi-cokes. The embodiment of the invention provides the preparation method of the water-coke slurry and the preparation method comprises the following steps: carrying out chilling on the semi-cokes, which are generated by coal gasification reaction or pyrolysis reaction, by utilizing water, so as to enable the semi-cokes to be self-broken; meanwhile, feeding the water into pores of the semi-cokes and mixing the water with the self-broken semi-cokes to form the slurry. The preparation method of the water-coke slurry, provided by the embodiment of the invention, is used for rapid slurry forming of the semi-cokes.

Description

technical field [0001] The invention relates to the technical field of water coke slurry, in particular to a preparation method of water coke slurry. Background technique [0002] The conversion and utilization of coal is to realize the separation and utilization of coal at a lower temperature, and carry out cascade utilization of each graded product, so this conversion method and conversion route have better advantages in energy saving and emission reduction . Specifically, starting from the chemical structure of coal, the coal is classified by low-temperature pyrolysis technology, and the coal is pyrolyzed into gas, liquid, and solid three-phase substances, and then used in a differentiated manner according to the physical and chemical properties of various pyrolysis products , Cascade extension processing. [0003] Among them, after the coal is separated, it will inevitably produce a large amount of low-sulfur, high-carbon porous semi-coke. At present, the main way of s...
