Coal water slurry integrated processing system and method thereof

Abstract

The invention relates to a coal water slurry integrated processing and treating system. An additive pump is mounted on a pipeline between an additive tank and a control valve; a weighing feeder is connected to a discharge port of a coal hopper; a discharge port of the weighing feeder is connected to a second feed port of a coal mill through a pipeline; a sodium hydroxide pump is installed on a pipeline between a sodium hydroxide storage tank and a third feeding port of the coal mill, a lime feeding conveyor is connected to a discharging port of the lime storage hopper, a discharging port of the lime feeding conveyor is connected with a fourth feeding port of the coal mill, and a discharging port of the coal mill is connected with a discharging tank of the coal mill. The invention further provides a coal water slurry integrated processing method. Compared with the prior art, the method has the following beneficial effects that in the coal slurry preparation process, coal quality characteristics and coal powder particle size distribution are relatively fixed, the anti-settling capacity of coal water slurry particles is good, and in the coal slurry transportation and storage process,the physical property uniformity can be kept. The production capacity is obviously improved, and huge economic benefits are brought.

Description

technical field [0001] The invention relates to a coal-water slurry integrated processing system and method, belonging to the technical field of coal gas. Background technique [0002] Coal water slurry is a kind of coal-based fluid fuel, which is made of about 65% coal, water and additives through physical processing, and has a certain particle size distribution, concentration and flowable slurry. Adopted in the field of coal gas technology. With the development of society and economy, international oil prices are on the rise, and fuel resources are increasingly in short supply. Coal water slurry is an ideal substitute for fuel oil, and the concentration and particle size of coal water slurry directly affect the effect of coal water slurry replacing fuel oil. Conventional pulping systems and existing coal-water slurry production methods mostly have problems such as small increase in coal slurry concentration, complicated process, poor operability, and high energy consumpt...
