Abstract

The invention discloses a method for preparing high-performance coal-water slurry by using bottom residue and waste emulsion, the steps are: (1) drying, pulverizing and sieving raw coal and bottom residue to obtain coal powder and bottom residue powder; (2) Add activated carbon powder to the metal processing waste emulsion after being pretreated by filtration and ultrafiltration, and stir and absorb to obtain the pretreated waste emulsion; (3) In parts by weight, 65~85 parts of coal Powder, 65~75 parts of pretreated waste emulsion, 15~28 parts of bottom residue powder and 1~2 parts of additives are mixed, and stirred evenly after ball milling to obtain high-performance coal water slurry. In the present invention, through the compatibility of the bottom residue, metal processing waste emulsion, activated carbon and coal powder, the interaction between wastes is used to effectively improve the various properties of the coal water slurry, and the prepared product has high solid content, good dispersibility and stability, High performance coal water slurry with high combustion efficiency.

Description

technical field

[0001] The invention relates to the technical field of waste treatment, in particular to a method for preparing high-performance coal-water slurry by using bottom residue and waste emulsion. Background technique

[0002] According to the new version of the "National Hazardous Waste List", the bottom residue belongs to HW06 waste organic solvents and wastes containing organic solvents; (including) organic solvent wastes are mostly harmful, flammable, corrosive, volatile or reactive and other characteristics, which are extremely harmful to the environment and human health. At present, the disposal methods of waste organic solvents in my country mainly include incineration and safe landfill, etc., and it is difficult to realize the harmless treatment of the bottom residue.

[0003] With the development of industry, my country has been facing the dual pressure of water resource shortage and water pollution. Among them, emulsion wastewater ranks first among all k...
