Abstract

The invention discloses a mould coal binder, and a preparation method thereof. The mould coal comprises, by mass, 0.5 to 0.75 parts of esterified swill-cooked dirty oil, 0.1 to 0.5 part of sodium carbonate, 3 to 5.5 parts of smithsonite, 85 to 91 parts of a consolidation agent, 0.3 to 0.5 part of basic zinc carbonate, 1 to 2 parts of potassium chloride, and 1 to 3 parts of polyacrylamide. No largeamount of pollutant is released in combustion of the mould coal binder, no secondary pollution is caused, and cleaning efficiency is high.

Description

technical field [0001] The invention relates to the field of coal molding and processing, in particular to a coal molding binder and a preparation method thereof. Background technique [0002] my country is rich in coal resources, but the efficiency of coal utilization is low, and the way of use is not environmentally friendly. The unreasonable use of coal not only wastes energy but also pollutes the environment. At present, the pollution problem of coal combustion is mainly caused by scattered coal burning. Compared with bulk coal, briquette coal is converted into briquette coal through special, clean, environmentally friendly and efficient coal processing, conversion and pollution control technologies. [0003] Specifically, briquette is a coal mixture of one or more properties, according to a certain proportion, adding additives (sulfur-fixing agent, binder, stabilizer, etc.) In order to improve the combustion effect, reduce the pollution of sulfur and smog, etc. [000...
