Description

Technical Field

[0001] The invention relates to the field of fluorine-containing wastewater treatment, in particular to a device for treating fluorine-containing wastewater. Background Art

[0002] The source of fluoride-containing wastewater is industrial wastewater, and fluoride-containing wastewater is also a very common type. For example, fluorite (calcium fluoride) is often used as a flux in the blast furnace ironmaking industry. Flue gas containing a large amount of fluoride is discharged during smelting. After the flue gas is washed, most of the fluoride in the flue gas is transferred into the washing water, producing fluoride-containing wastewater. Because the fluoride ion concentration of fluoride-containing wastewater is high and the content of organic pollutants is high, these wastewaters must strictly comply with the emission standards formulated by the state and undergo strict pretreatment before being discharged into the nature.

[0003] At present, when treating fluoride-containing wastewater, quicklime is mostly added in the primary reaction tank to react with calcium hydroxide Ca(OH)2 and fluoride ions F - The fluorine element in the wastewater can be precipitated through the reaction, but when quicklime meets water, a large amount of heat will be generated, and the heat will cause the water to evaporate and produce steam. Under the influence of the steam, the quicklime may fall into the water more slowly, thereby affecting the overall speed of fluoride-containing wastewater treatment. In addition, if too much quicklime is added at one time, heat accumulation may occur, causing water to splash, which also has a certain impact on the treatment of fluoride-containing wastewater.

[0050] Working principle: In the treatment of fluoride-containing wastewater, some treatment devices need to add lime to the fluoride-containing wastewater. According to the chemical reaction formula, Ca(OH)2+2F - =CaF2↓+2OH - , through calcium hydroxide Ca(OH)2 and fluoride ion F- The reaction can precipitate the fluorine element in the wastewater, and after the reaction, the water is discharged into the primary sedimentation tank.

[0051] The staff can discharge fluorine-containing wastewater into the primary treatment pool 1, and then use the feed pipe 6 to add lime to the lime shell 5. Then, the extrusion mechanism 7 can be used. Under the action of the high-speed motor 71, the first transmission rod 72, the driving gear 73, the driven gear 74, the second transmission rod 75, the third transmission rod 76 and the driving rotating rod 77 can work, and then the conveying auger 78 fixed on the surface of the driving rotating rod 77 can slowly squeeze the lime in the lime shell 5 to make it fall into the discharge barrel 12.

[0052] When the high-speed motor 71 is working, the fifth transmission rod 82, the sixth transmission rod 83 and the stirring turntable 84 can be operated under the action of the fourth transmission rod 81, and then the wastewater can be stirred under the action of the driving plate 85, so that the wastewater moves, thereby improving the contact ability between the wastewater and lime.

[0053] When the high-speed motor 71 is working, the first connecting block 91 fixed to one end of the output shaft of the high-speed motor 71 can enable the connecting rod 92 to work, and then the rotating column 93 arranged at one end of the connecting rod 92 can enable the driving fork 94 to work, and through the restriction of the limit member 95, the driving fork 94 can drive the second connecting block 96 to shake, and then under the action of the first connecting block 91, the reciprocating plate 101 can reciprocate.

[0054] At this time, the connecting plates 102 fixed on both sides of the surface of the reciprocating plate 101 can enable the connecting rope 103 to drive the ash bucket 104 to rise and fall, and the connecting column 111 and the push rod 112 fixed in the inner cavity of the ash bucket 104 can work, and then when the ash bucket 104 reaches the specified position, the push rod 112 and the sealing plate 115 can be fitted, and after the sealing plate 115 is lifted up, the lime in the discharge bucket 12 can fall into the ash bucket 104, and in addition, under the action of the active rotating rod 77, the rotating disk 131 can rotate, and then under the action of the top block 132, the force block 133 drives the auxiliary plate 134 to reciprocate, and under the action of the auxiliary plate 134, the lime can be pushed.

[0055] At this time, there is a certain amount of lime in the ash bucket 104. When the ash bucket 104 descends, the driving rod 142 can be attached to the surface of the bonding plate 141, and then driven by the driving rod 142, the cover shaft 143 and the bucket cover 145 are turned over. When the bucket cover 145 is turned over, wastewater flows into the ash bucket 104 from the upper side and the lower side of the ash bucket 104, thereby flushing the lime, and the lime falls into the primary treatment tank 1 under the action of its own gravity, so that the lime and wastewater participate in the reaction. Through this arrangement, the lime can fall into the interior of the wastewater to participate in the reaction, thereby avoiding the large amount of heat generated by the reaction of lime and water, and the heat further evaporates the water to produce water vapor, which makes the lime unable to fall into the water.
