Description

Technical Field

[0001] The invention relates to the technical field of quartz sand alkali scrubbing circulating water treatment, in particular to a quartz sand alkali scrubbing circulating water purification treatment system. Background Art

[0002] Due to the scarcity of non-metallic mineral resources and the exhaustion of high-grade mineral resources, some low-grade non-metallic minerals have become the main direction of mining now, especially in the field of quartz beneficiation. For these low-grade quartz ores or quartz sands, more complex beneficiation processes and procedures are required to enrich and purify the quartz. Alkali rubbing is an indispensable beneficiation process for these low-grade quartz ores or quartz sands. However, a large amount of mud and humus will be generated during the alkali rubbing operation (the mud and humus attached to the surface of the quartz sand are stripped off during the alkali rubbing process), and a large amount of mud and humus will have a deteriorating effect on the alkali rubbing operation, thereby affecting the final concentrated sand index of the entire beneficiation process. The present invention proposes a purification treatment system for quartz sand alkali rubbing circulating water to perfectly separate the mud and humus from the water in the alkali rubbing water.

[0003] The sedimentation rate of mud and humus in alkaline water is slow and unstable in the natural state (affected by water flow disturbance). The commonly used method is to directly use a plate and frame filter press to separate mud and water. This treatment method will increase the workload and increase production costs. At the same time, it has a poor treatment effect on the mud and humus in alkaline water. Summary of the invention

[0004] The purpose of the present invention is to provide a purification treatment system for quartz sand alkali scrubbing circulating water to solve the shortcomings of the above-mentioned background technology.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0007] Step 1: adding a connector, a surfactant and a co-solvent composition to the alkaline scrubbing circulating water, and then passing the water through a pipeline into a purification device for purification and filtration;

[0008] Step 2: After the circulating water is washed with alkali by adding a linker, a surfactant and a co-solvent composition and enters the purification device, the mud and humus in the alkaline water react with the added medicine to form complex flocs;

[0009] Step 3: The alkaline scrubbing circulating water and the drug in step 2 circulate in the tank of the purification equipment to carry out a sufficient chemical reaction, so that the mud and humus in the alkaline scrubbing circulating water produce complex flocs, and at the same time, bubbles are generated at the bottom of the purification device to aerate the alkaline scrubbing circulating water, so that the generated complex flocs float, and then the floated complex flocs are cleaned to separate them from the alkaline scrubbing circulating water;

[0010] Step 4: Pass the separated complex flocs into a plate and frame filter press for solid-liquid separation.

[0011] As a further scheme of the present invention: the synthesis of Gemin i type cationic diquaternary ammonium salt is to weigh a certain mass of dibromooctane and pour it into a three-necked flask, and at the same time add a certain amount of hexadecylamine to ensure that the molar ratio of dibromoalkane to alkyl tertiary amine is about 1:1.5 to 1:4; at the same time, add solvent ethanol, pass nitrogen, heat and reflux in an oil bath at 70 to 90° C., terminate the quaternization reaction after 24 to 72 hours, recover the synthetic product, and obtain the target product.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1

[0029] See also Figure 1-Figure 5 As shown, the present invention is a purification treatment system for quartz sand alkali scrubbing circulating water, comprising the following steps:

[0030] Step 1: adding a connector, a surfactant and a co-solvent composition to the alkaline scrubbing circulating water, and then passing the water through a pipeline into a purification device for purification and filtration;

[0031] Step 2: After the circulating water is washed with alkali by adding a linker, a surfactant and a co-solvent composition and enters the purification device, the mud and humus in the alkaline water react with the added medicine to form complex flocs;

[0032] Step 3: The alkaline scrubbing circulating water and the drug in step 2 circulate in the tank of the purification equipment to carry out a sufficient chemical reaction, so that the mud and humus in the alkaline scrubbing circulating water produce complex flocs, and at the same time, bubbles are generated at the bottom of the purification device to aerate the alkaline scrubbing circulating water, so that the generated complex flocs float, and then the floated complex flocs are cleaned to separate them from the alkaline scrubbing circulating water;

[0033] Step 4: Pass the separated complex flocs into a plate and frame filter press for solid-liquid separation. The plate and frame filter press is a prior art, so no further elaboration is made here.

[0034] The synthesis of Gemin I type cationic diquaternary ammonium salt comprises the following steps: weighing a certain mass of dibromooctane and pouring it into a three-necked flask, adding a certain amount of hexadecylamine at the same time, ensuring that the molar ratio of dibromoalkane to alkyl tertiary amine is about 1:1.5-1:4; adding solvent ethanol at the same time, introducing nitrogen, heating and reflux in an oil bath at 70-90°C, terminating the quaternization reaction after 24-72 hours, recovering the synthesized product, and obtaining the target product.

[0035] The cosolvent is one or more combinations of polysorbate, urea and acetic acid, and the linker is serpentine, talcum starch, protein, animal glue and sodium alginate.

[0036] By adding a connector, a surfactant and a co-solvent drug to the treated alkaline scrubbing circulating water and passing it into a purification device at the same time, the mud and humus in the alkaline scrubbing circulating water react with the drug to produce complex flocs, and at the same time the physical properties of the surface of the produced complex flocs are changed to separate them from water. Subsequently, the purification device is aerated to make the bubbles drive the complex flocs to float to the water surface and then clean them out. Subsequently, the cleaned complex flocs are passed into a plate and frame filter press for treatment to separate the alkaline water in the complex flocs and reuse the treated alkaline water, which can reduce a certain amount of workload and reduce the corresponding production cost, thereby achieving full and effective removal of mud and humus in the alkaline scrubbing circulating water and making the treatment more convenient.

[0037] Please refer to Table 1 and Table 2. The present invention uses a mixed solvent to treat the alkaline circulating water, mainly using a connector, a surfactant, a co-solvent, etc. to separate the sediment in the alkaline circulating water into solid and liquid. The specific steps of the test are as follows:

[0038] The surfactant is a synthetic quaternary ammonium salt, characterized in that a certain mass of 1,8-dibromooctane is weighed and poured into a three-necked flask, and a certain amount of hexadecylamine is added at the same time to ensure that the molar ratio of dibromoalkane to alkyl tertiary amine is about 1:1.5-1:4; solvent ethanol is added at the same time, nitrogen is introduced, and the mixture is heated and refluxed in an oil bath at 70-90°C for 24-72 hours to terminate the quaternization reaction. The synthetic product is recovered to obtain the target product.

[0039] Take a certain amount of alkali to wipe the circulating water, stir it thoroughly and evenly to avoid the occurrence of stratification, so as to obtain homogenized circulating water.

[0040] 1000 ml of homogenized alkaline circulating water was taken out, and the supernatant was taken after it was allowed to stand for 5 min, 10 min, 20 min, and 30 min, and the change in turbidity value was measured.

[0041] The synthesized surfactant is mixed with a cosolvent, a connector and water in a certain proportion, wherein the surfactant accounts for 15-35%, the cosolvent accounts for 10-20%, the connector accounts for 20-30% and the rest of the water, and the mixture is stirred evenly.

[0042] Take the alkaline circulating water mixed in the previous step, pour it into a 1000ml standard beaker, and stir continuously in the beaker to ensure the homogenization of the alkaline water.

[0043] Take 5 ml of the mixed solvent prepared above, add it into the homogenized alkaline water, and continue stirring for 10 minutes to allow the mixed solvent and the alkaline water to fully contact and react. Let it stand for 0.5 hours, observe the changes in the mixed solution, and take the clarified liquid to measure its turbidity value.

[0044] Take 5 ml of mixed solvent and 1000 ml of alkaline circulating water respectively, shorten the stirring time to 5 min, let it stand for 0.5 h, observe the changes in the mixed solution, and take the clarified liquid to measure its turbidity value.

[0045] Take 5 ml of mixed solvent and 1000 ml of alkaline circulating water respectively, stir for 5 minutes, let stand for 20 minutes, observe the changes in the mixed solution, and take the clarified liquid to measure its turbidity value.

[0046] Take 5 ml of mixed solvent and 1000 ml of alkaline circulating water respectively, stir for 5 minutes, let stand for 10 minutes, observe the changes in the mixed solution, and take the clarified liquid to measure its turbidity value.

[0047] Take 5 ml of mixed solvent and 1000 ml of alkaline circulating water respectively, stir for 5 minutes, let stand for 5 minutes, observe the changes in the mixed solution, and take the clarified liquid to measure its turbidity value.

[0048] The commonly used flocculant PAM was prepared into a solution with a mass fraction of 0.1%.

[0049] Take 1000ml of alkaline circulating water and 5ml of the prepared PAM solution, stir for 5min, let stand for 30min, observe the changes in the solution, and take the supernatant to measure its turbidity value.

[0050] Take 1000ml of alkaline circulating water and 5ml of the prepared PAM solution, stir for 5min, let stand for 20min, observe the changes in the solution, and take the supernatant to measure its turbidity value.

[0051] Take 1000ml of alkaline circulating water and 5ml of the prepared PAM solution, stir for 5min, let stand for 10min, observe the changes in the solution, and take the supernatant to measure its turbidity value.

[0052] Take 1000ml of alkaline circulating water and 5ml of the prepared PAM solution, stir for 5min, let stand for 5min, observe the changes in the solution, and take the supernatant to measure its turbidity value.

[0053] The turbidity value after adding PAM was recorded and compared with the turbidity value after mixed solvent treatment under the same conditions.

[0054] The beneficial effect of adopting the above measures is that under the same conditions, the turbidity value of the alkaline circulating water after being treated with the mixed solvent is lower than the turbidity value after being treated with PAM.
