Description

Technical Field

[0001] The invention relates to the technical field of coal-water slurry additive equipment, and in particular to a filtering device for preparing coal-water slurry additives. Background Art

[0002] Coal-water slurry is a low-pollution, high-efficiency, pipeline-transportable coal-based fluid fuel that is a substitute for oil and is made from about 65% coal, 34% water and 1% additives through physical processing. It has changed the traditional way of coal combustion and has shown great advantages in environmental protection and energy saving. Coal-water slurry additives include dispersants, stabilizers and other auxiliary chemical agents according to their functions, such as defoamers, pH adjusters, enzyme inhibitors, surface modifiers and promoters. Dispersants and stabilizers are indispensable. Additives are closely related to the properties of raw coal and water. Reasonable additive formulas must be determined after testing based on the properties of the coal used for pulping and the user's requirements for the quality of coal-water slurry products.

[0003] Commonly used water-coal slurry additives need to be produced and processed to meet the production needs of water-coal slurry. During the preparation process, the water-coal slurry additives are prepared by mixing multiple components into a solution and then used. During the mixing process, there may be some insoluble or insoluble substances. These insoluble or insoluble substances flow into the water-coal slurry and affect the performance of the water-coal slurry. For this reason, we propose a filtering device for preparing water-coal slurry additives. Summary of the invention
