preparation example Construction

[0036] The preparation method of the above simulated low-level organic waste liquid pyrolysis incineration suspension formula comprises the following steps:

[0037] Step 1, prepare component A; first measure tributyl phosphate with a volume ratio of 26.55%, then mix aviation hydrogenated kerosene with a volume ratio of 73.23% into tributyl phosphate, stir for 10 minutes, and then dibutyl phosphate by The volume ratio is 0.12%, mixed with the mixed solution of tributyl phosphate and kerosene, and set aside;

[0038] Step 2, preparing component B; first mix 27% mass ratio of phosphorus-fixing agent calcium hydroxide with 38% deionized water, stir for 10 minutes, then add 35% active agent into the stirring milk of lime, and then Stir for 10min, set aside;

[0039] Step 3, preparing the simulated waste liquid suspension; while stirring, slowly pour the B component prepared in step 2 into the stirring simulated low-level organic waste liquid A, and stir for 30 minutes to form a u...

Abstract

The invention relates to a formula for simulating low-level organic waste liquid pyrolysis incineration suspension and a preparation method thereof, and relates to the field of low-level level waste liquid treatment. The formulation of the present invention includes: A component, B component and C component; wherein, A component is a simulated low-level organic waste liquid, containing 20-30% of tributyl phosphate, 70-78% of Aviation hydrogenated kerosene and 0-2% dibutyl phosphate; component B is calcium hydroxide suspension, containing 25-30% by mass ratio of phosphorus-fixing agent calcium hydroxide, 32-40% active agent and 30-30% 40% deionized water; component C is an additive of analytically pure magnesium carbonate. The formula of the present invention overcomes the defects of the prior art. The suspension prepared according to the formula has good stability, less sedimentation, low viscosity, and is easy to transport. The active agent and phosphorus-fixing agent in the formula are all domestically produced, which avoids the introduction of foreign technical barriers.

Description

technical field [0001] The invention relates to the field of low-level waste liquid treatment, in particular to a suspension formula for simulating a low-level level organic waste liquid-TBP / OK pyrolysis and incineration process and a preparation method thereof. Background technique [0002] In the reprocessing of spent fuel at home and abroad, the Purex process occupies a dominant position. At present, the Purex process adopted by various countries has three extraction cycles, namely, the decontamination and separation cycle, the plutonium purification cycle and the uranium purification cycle. Each reprocessing plant has changed its process combination according to the specific activity of the feed liquid and the requirements for decontamination, but all these processes use TBP as the extraction agent to extract uranium and plutonium, kerosene as the diluent, and reduction reaction. Extraction is the basis for separation. During the production process of Purex process, rad...
