Abstract
The present invention relates to the manufacture method of a kind of inorganic salts in the chemical field, particularly a kind of method with preparing high-purity technical calcium carbonate from calcium carbide dregs.
Technical characterictic of the present invention is: main by the pre-treatment to carbide slag, and with pretreated carbide slag and ammonium chloride and water wiring solution-forming by a certain percentage, after filtration, after the clarification, feed carbon dioxide and carry out carbonization, again through dehydration, washing, dry, cooling, pulverize, screening, thereby make high-purity technical calcium carbonate.
High-purity technical calcium carbonate has extensive use as the filler of products such as rubber, plastics, paint.
Description
The present invention relates to the manufacture method of a kind of inorganic salts in the chemical field, particularly a kind of method with preparing high-purity technical calcium carbonate from calcium carbide dregs.
In the clear 62-36021 of Japanese Patent, a kind of mixed aqueous solution with high-quality calcium hydroxide and ammonium chloride is disclosed, feed the method that carbon dioxide is produced purity calcium carbonate, its weak point is that used calcium hydroxide must prepare with high-quality unslaked lime.
Purpose of the present invention provides a kind of method that the product carbide slag is produced high-purity technical calcium carbonate of paying with acetylene industry.The three wastes that solved simultaneously the acetylene industrial residue are again handled problems.
Technical characterictic of the present invention is:
A, carbide slag is carried out pre-treatment,, and then place under 1201 ℃ to the 1350 ℃ temperature and heat, after reaching assigned temperature, be incubated 30 minutes to 60 minutes promptly with carbide slag preheating oven dry under 150 ℃ to 200 ℃ temperature through dehydration.
B, remove after the pre-treatment a large amount of impurity in the carbide slag, be about to through pretreated carbide slag by following weight ratio; Carbide slag after the pre-treatment: ammonium chloride: water=(1～1.6): 2: (6～10) wiring solution-forming, through fully stirring the after-filtration clarification.
C, feed above-mentioned solution, till reaction solution PH≤7 o'clock with carbon dioxide.
D, again through dehydration, washing, dehydration, dry, cooling, pulverize, screening.
The present invention compared with prior art has the following advantages: product purity height, its raw material are carbide slag, and the source is wide, and have substituted high-quality unslaked lime with carbide slag, for country has saved a large amount of mining depositses, have solved the acetylene industrial residue three wastes again and have handled problems.
The embodiment of the invention:
1, the pretreated carbide slag of learning from else's experience, press following weight ratio: carbide slag after the pre-treatment: ammonium chloride: water=1.5: 2: 10 wiring solution-formings, after filtration, clarification back feeding carbon dioxide carries out carbonization, till PH≤7 o'clock, through dehydration, washing, drying, cooling, pulverizing, screening, its calcium carbonate content of products obtained therefrom reaches 99.91% again.
2, the pretreated carbide slag of learning from else's experience is by following weight ratio; Carbide slag after the pre-treatment: ammonium chloride: water=1.2: 2: 7 wiring solution-formings, after filtration, clarification back feeds carbon dioxide and carry out carbonization, and till PH≤7 o'clock, again through dehydration, washing, drying is pulverized, screening, the products obtained therefrom calcium carbonate content reaches 99.83%.
Claims (1)
1, the manufacture method of inorganic salts in a kind of chemical field, particularly a kind of method with preparing high-purity technical calcium carbonate from calcium carbide dregs.
Prior art is characterized as: with the mixed aqueous solution of high-quality calcium hydroxide and ammonium chloride, feed carbon dioxide and produce high-purity technical calcium carbonate.
Technical characterictic of the present invention is:
A, carbide slag is carried out pre-treatment, promptly with through the carbide slag of dehydration under 150 ℃ to 200 ℃ temperature, preheating, oven dry, and then place under 1201 ℃～1350 ℃ temperature and heat after reaching assigned temperature, are incubated 30 minutes to 60 minutes.
B, remove after the pre-treatment a large amount of impurity in the carbide slag, be about to through pretreated carbide slag, by following weight ratio; Carbide slag after the pre-treatment: ammonium chloride: water=(1～1.6): 2: (6～10), wiring solution-forming is through fully stirring after-filtration, clarification.
C, feed above-mentioned solution, till reaction solution≤7 o'clock with carbon dioxide.
D, again through dehydration, washing, dry, cooling, pulverize, screening.
