Problems solved by technology

These methods have played a certain role in the treatment of waste liquid, but they more or less have the disadvantages of slow treatment speed, long cycle, consumption of a large amount of chemicals, high energy consumption, high treatment cost, and large floor space. Often accompanied by the possibility of secondary pollution

Abstract

The invention discloses waste alcohol coal-slurry as well as the preparation method and the application thereof. The components and parts by weight are as follows: 100-180 potions of coal powder, 4-99 portions of waste alcohol, 0-90 portions of water and 0.1-3 portions of dispersing agent. The preparation method of the waste alcohol coal-slurry has simple operation because the waste alcohol is directly used without the pretreatment of concentration or solid-liquid separation, and the like, shortens the waste alcohol treatment period, lowers the energy consumption, and does not basically produce the secondary pollution. The waste alcohol can replace partial coal and water, thereby saving resources. The waste alcohol coal-slurry is placed for a long time without producing hard settlement, has good fluidity so as to be suitable for being transported by a pump, and can be used as fuel for combustion or as gasified raw material for preparing gas.

Description

technical field [0001] The invention relates to an alcohol waste liquid coal slurry and its preparation method and application, in particular to a preparation method and application of a high-concentration alcohol waste liquid coal slurry. Background technique [0002] Alcohol is an important basic chemical raw material, which is widely used in chemical, food, medical and health fields, and can be used as alcohol base, extractant, detergent, solvent, surfactant, etc. my country is a big country in alcohol production, with an annual output of about 3 million tons of alcohol by fermentation, accounting for the third place in the world's total output. However, the alcohol waste liquid discharged by fermentation alcohol enterprises is one of the most serious pollution sources in the food and fermentation industry, which has become an important factor restricting the development of the alcohol industry. [0003] The raw materials for alcohol production are mainly grains (corn, d...
