Abstract

The invention relates to a high-efficiency coal water slurry stabilizer which is prepared from the following raw materials in parts by weight: 8-14 parts of sodium ethylene diamine tetracetate, 3-6 parts of hydroxyethyl cellulose, 1-2 parts of polyepoxysuccinic acid, 1.5-2.2 parts of hydroxymethyl cellulose, 2-4 parts of air entraining agent, 3-8 parts of water reducing agent, 10-14 parts of smellless kerosene, 8-12 parts of di-n-octyl tin oxide, 2-4 parts of sodium polyacrylate, 8-13 parts of guar gum, 3-6 parts of high molecular surfactant, 2-4 parts of cellulase and 3-5 parts of arabic gum. The high-efficiency coal water slurry stabilizer can increase the viscosity of the coal water slurry, enhances the stability of the slurry, has the advantages of favorable effect, wide raw material sources for preparing the suspension stabilizer and low tendency to precipitation, and reduces the resistance between coal granules.

Description

technical field [0001] The invention relates to a high-efficiency coal-water slurry stabilizer. Background technique [0002] Coal water slurry is an economical, clean, liquid fuel and chemical raw material that can replace oil and natural gas. It has been widely used in heating, chemical synthesis gas, power generation, industrial furnaces and other fields instead of oil and gas; it has high combustion efficiency High, convenient load adjustment, energy saving, reducing environmental pollution, improving working conditions and other advantages. However, since coal-water slurry is a coarse-grained suspension, it is a dynamically unstable system, and the main method to stabilize it is to make it a thixotrope. That is, when the coal slurry is left still, it will be structured and has a high shear stress. When it is applied, once the external force is applied, the viscosity can be reduced rapidly, and it has good fluidity. It can restore the original structural state when it i...
