Embodiment Construction

[0012] The present invention will be further described in conjunction with the accompanying drawings of the above-mentioned embodiments.

[0013] As shown in the figure, in the treatment method of the glucuron lactone mother liquor according to the present invention, the glucuron lactone mother liquor is prepared in the preparation tank 1 so that the concentration is 20, 22, 25, 28, 30, 33, 36, 40 Concentrated mother liquor with a concentration of Baume degree is pumped into the combustion chamber 5 of the boiler with a high-pressure pump 3 for atomization and combustion.

[0014] Exhaust combustion tail gas inspection: collect the exhaust gas after combustion, the combustion is complete, neutral, non-corrosive, without any corrosion damage to pipes and boiler facilities and accessories, and there is less smoke and dust in the tail gas.

[0015] In the direct atomization combustion test in a boiler without coal combustion, the effect is also good.

[0016] The same test is ca...

Abstract

The present invention relates to a method for processing glucurolactone mother liquor. Said method includes the following steps: firstly, comcentrating the concentration of glucurolactone mother liquor to 20-40 Baume deg., then adopting high-pressure spray-combustion method to make the glucurolactone mother liquor undergo the presses of atomized combustion treatment. Said atomized combustion is implemented in the thermotechnical equipment.

Description

technical field [0001] The invention relates to a treatment method for glucuron lactone mother liquor, belonging to the technical field of industrial waste liquid treatment. Background technique [0002] Glucuron lactone is clinically used for the treatment of liver diseases, or as an adjuvant therapy for liver diseases. Glucuron lactone mother liquor is the waste liquid discharged during the production process of glucuronolactone drug. It is very acidic and has a pH value of about 2 to 3, causing serious pollution. Concentrate, then distill off part of ethanol and acetic acid, then neutralize with alkali, adjust the pH to neutral, put it into the sewage treatment tank for sewage treatment. The cost of this method is very high, not only need to invest a large amount of manpower, but also need to occupy a large amount of neutralization equipment and need to consume a large amount of alkali raw materials, the energy consumption is very large, and at the same time, how to disc...
