Abstract

The invention discloses a boiler combustion method of a biochemical industry alcohol waste liquid. The method is as follows: preheated air is sent into a boiler furnace through a first air-delivery duct and a secondary air-delivery duct which are successively arranged from bottom to top in the boiler furnace, and is mixed with the biochemical industry alcohol waste liquid sprayed into the boiler furnace for combustion; the temperature of the preheated air is 80-150 DEG C; the air pressure of the first air-delivery duct is 500Pa-1200Pa, and the first air rate is 0.35-0.6; the air pressure of the secondary air-delivery duct is 1500Pa-3000Pa, and the secondary air rate is 0.3-0.5; the sum of the secondary air rate and the secondary air rate is 1; and the spraying pressure of the biochemical industry alcohol waste liquid is 0.05-0.2MPa. The waste liquid combustion efficiency is high, the combustion is sufficient, the purity of produced sodium carbonate is above 98% and the boiler thermal efficiency is high and can reach above 75%.

Description

technical field

[0001] The invention belongs to the treatment technology of chemical waste liquid pollutants, and in particular relates to a treatment technology of biochemical alcohol waste liquid, in particular to a method for carrying out combustion treatment of biochemical alcohol waste liquid. Background technique

[0002] The technology of producing chemical alcohol from corn and corn stalks has been gradually used now. It uses the raw materials such as corn and corn stalks after starch extraction to pass through a specific pretreatment process and send them to a stainless steel pressure reaction vessel. Under the action of sodium carbonate, it reacts with chemical solvents such as sodium carbonate at a certain pressure and temperature, and separates chemical alcohols (ethylene glycol, propylene glycol, butanediol, etc.) through a series of processes.

[0003] The waste liquid produced by the production of chemical alcohol is a mixture of inorganic and organic substanc...
