Abstract

The invention discloses special briquette coal for water treatment of lime. The special briquette coal comprises bituminous coal, sawdust powder, rice hull powder, potassium permanganate, potassium perchlorate, shell powder, peanut meal, lignin, sodium stearate, aluminum powder, magnesium powder and a proper amount of water. A method for preparing the special briquette coal used for water treatment of lime comprises the following steps: (1) mixing sodium stearate with water, adding shell powder and lignin, and successively carrying out mixing, standing, suction filtration, washing, drying andgrinding to obtain modified shell powder; and (2) uniformly stirring and mixing bituminous coal, sawdust powder, rice hull powder and peanut meal, adding lignin and water, carrying out uniform mixing,adding the modified shell powder, carrying out uniform mixing, finally adding potassium permanganate, potassium perchlorate, aluminum powder and magnesium powder, carrying out uniform mixing, moldingthe formed mixture in a molding machine, and successively carrying out drying, cooling to room temperature and packaging to obtain the special briquette coal for water treatment of lime. The coal iscombusted more sufficiently and thoroughly, so a combustion heat value can be increased; and bituminous coal, sawdust powder and the like are used as main combustion raw materials, so waste utilization can be achieved, and environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of coal combustion, and in particular relates to a special shaped coal for water treatment lime and a preparation method thereof. Background technique [0002] In our country, lime has a wide range of sources and relatively low price. Lime is widely used in water treatment and is an indispensable agent in water treatment. Lime is a cheap water treatment agent, used as water softener, PH regulator, etc. It can remove phosphate and most heavy metals, reduce BOD, kill bacteria and viruses, remove ammonia, etc., and has good effects . Lime with good performance can play a very good treatment effect in water treatment. Lime is obtained by calcination in a lime kiln. Coal needs to be added during the lime calcination process. Currently, the coal used in the lime preparation process still has incomplete combustion due to differences in material selection, proportioning and processing technology. Problems such as...
