Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, in particular to an environmentally friendly high-salt water treatment process. Background Art

[0002] High-salt water is a technical difficulty in industrial wastewater treatment. It has the characteristics of strong corrosiveness, high solubility and biological toxicity. Direct discharge will seriously damage the water ecology and soil environment. The composition of high-salt water is complex and diverse, and its specific material composition is highly dependent on the source industry and production process. It can be mainly divided into four categories: inorganic salts, organic matter, heavy metals and trace pollutants.

[0003] The patent with application number CN202021444108.7 mentions "a high-salt water treatment equipment". This patent allows the high-salt water to undergo one rough processing and one reprocessing effect through the cooperation of the heating layer, reprocessing layer, placement layer and centrifuge, and then enter the placement layer for sedimentation and flow into the collection box. The delivery water pump sends the high-salt water into the inner shell of the separator, which can not only preheat the high-salt water, but also use the high-salt water to reduce the temperature of the inner shell of the separator to achieve rapid separation.

[0004] However, when reacting and precipitating high-salt water, multiple sets of equipment are needed for treatment. As a result, a lot of time is needed to transfer the high-salt water during treatment, which greatly affects the actual precipitation speed. In addition, when performing hot steam condensation desalination and deslagging treatment directly, the supersaturated solution condenses in the heating equipment, affecting the effect and efficiency of thermal evaporation, thereby greatly affecting the actual treatment efficiency of the high-salt water. Summary of the Invention

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] 1. It is equipped with a heavy pressure spray assembly, which feeds materials in sections at multiple positions through a feeding and separation pipe, cooperates with a stirring motor to drive the stirring operation frame to rotate, and a transposition motor to drive the multi-barrel mixing frame to rotate, and continuously changes its feeding position to achieve uniform distribution of raw materials and ensure sufficient contact with the reaction. Through continuous injection of lime slurry, soda ash and magnesium agent, and through multi-layer simultaneous series reaction, high brine deacidification, decalcification, demagnesium and desiliconization treatment are achieved. Through multi-layer treatment of a single device, high brine flow reaction is achieved, and the waiting time for high brine transportation is reduced. At the same time, multiple groups of series reactions are used to improve the effect and efficiency of precipitation. Cooperate with the extraction operation pump and the series discharge pipe to continuously inject high brine into the mixing and flocculation barrel, and promote the rotation and mixing of high brine and flocculant through the mixing motor and the mixing stirring frame. Through continuous water inlet and continuous mixing, and in conjunction with continuous discharge, rapid flocculant mixing treatment is achieved, ensuring the stability and speed of continuous treatment of high brine.

[0045] The high-salt water in the relay preheating box is injected into the pressurized heating barrel through the liquid extraction operation pipe and the extraction operation pump, and the pressure in the pressurized heating barrel is increased by the inlet and outlet control pipe and the pressure-controlled air pump, and the pressure in the step-down electric heating box is reduced. The boiling point of the water is increased by high pressure, and the high-temperature high-salt water is injected into the inner side of the step-down electric heating box in conjunction with the extraction operation pump and the extraction and injection linkage pipe. The boiling point is lowered by the low-pressure ring, a large amount of hot steam is generated and a supersaturated solution is formed at the same time. The high-salt water is superheated by high-pressure heating, and low-pressure boiling is combined to achieve separation of heating and supersaturated condensation, thereby avoiding the influence of condensate on heat conduction and equipment during continuous heating, improving the stability of the high-salt water treatment, ensuring the effect and efficiency of thermal evaporation, and improving the efficiency of the high-salt water treatment;

[0046] Through the continuous automatic flow of high-salt water, combined with rotation and multi-position feeding and mixing, high-salt water precipitation is achieved to remove part of the inorganic salts. Combined with continuous inlet and outlet water treatment and flocculation mixing, high-salt water continuous treatment is achieved. Through pressurized heating and pressure-reduced evaporation treatment, the problems in the existing technology that high-salt water reactions require constant replacement of equipment, increase the time for transfer, and multiple groups of reactions cannot cooperate with each other are effectively solved. The number of transfers can be reduced during treatment, the speed of reaction coordination and precipitation treatment can be increased, and heating and condensation can be separated to avoid the influence of impurities generated by condensation on thermal evaporation, thereby improving the effect and efficiency of thermal evaporation, thereby effectively improving the speed and effect of high-salt water treatment.

[0047] 2. A relay sedimentation component is provided. The centrifugal treatment frame is driven to rotate by the centrifugal motor. The centrifugal treatment frame is used to promote the full mixing of flocculant and high-salt water, and the flocculants in the high-salt water are separated from the high-salt water in conjunction with the high-speed rotation centrifugation. The separation electric push rod drives the separation interception net to push the flocculants downward, and the supernatant is extracted by the injection treatment pump and the extraction linkage pipe. The series discharge pipe is opened by operating the solenoid valve to discharge the turbid liquid in the centrifugal operation barrel into the multi-division integration box. The flocculants are separated from the high-salt water by the coarse interception plate and the fine mesh plate. The high-salt water is extracted by the external separation pipe and the injection treatment pump. Through the simultaneous operation of multiple groups, continuous inlet and outlet water treatment of the equipment is achieved, and the treatment effect is improved. At the same time, the upper and lower liquid separation and interception liquid separation cooperate with each other to achieve full extraction of high-salt water and independent isolation of flocculants, thereby improving the recovery rate and recovery speed after high-salt water treatment, further improving the continuous processing speed of the equipment, and ensuring the overall production efficiency.

[0048] In summary, through the cooperation of the heavy pressure spray component and the relay separation component, through flocculation mixing, flocculation stirring adsorption, centrifugal separation and double injection treatment, the continuous inflow and outflow of high-salt water can be achieved, the speed of high-salt water deslagging and purification can be improved, and the effect and efficiency of high-salt water treatment can be guaranteed. Through the cooperation of multiple groups of precipitation treatment and hot steam condensation treatment, the purification treatment of high-salt water and the water purification treatment of high-salt water can be achieved, and the overall treatment effect and efficiency can be improved.

It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0064] Example: Figure 1-9 As shown, the present invention provides a technical solution, an environmentally friendly high-salt water treatment process, comprising the following steps:

[0065] S1, salt solution settling: salt solution, lime slurry, soda ash and magnesium sulfate are gradually added layer by layer from the inside to the outside into the reaction interception barrel 202 by integrating the operation rack 1 and the feeding separation pipe 209. The transposition motor 203 drives the multi-barrel mixing rack 204 to rotate, and the stirring motor 207 drives the stirring operation rack 208 to promote liquid stirring. At this time, the salt solution gradually reacts with the lime slurry, soda ash and magnesium sulfate to form a precipitate, which is intercepted by the multi-net pressing rack 206 to achieve preliminary treatment of the salt solution;

[0066] S2, flocculation extraction; by extracting the operating pump 231 and the series discharge pipe 217 to inject the salt solution into the mixing flocculation barrel 210, the mixing motor 213 drives the mixing stirring frame 214 to promote the mixing of the salt solution with the internal flocculant, and the suspended matter in the water is adsorbed and precipitated, and the flocculants and liquid are separated by the pressure-separating electric push rod 215, the pressure-separating grid 216, the multi-row operating pipe 218 and the extraction operating pump 231 to achieve secondary treatment of the salt solution;

[0067] S3, centrifugal sedimentation: The liquid is injected into the centrifugal operation barrel 303 through the multiple rows of operation pipes 218 and the extraction operation pump 231, and the centrifugal treatment is carried out in conjunction with the centrifugal motor 304 and the centrifugal treatment frame 305. The multi-division integration box 301, the separation interception net 307, the extraction linkage pipe 308, the coarse interception plate 309 and the fine mesh plate 310 are used for static sedimentation and filtration separation to achieve three-time treatment of the salt solution;

The liquid is then discharged through the extraction operation pipe 230 and the extraction operation pump 231. By reducing the pressure, the hot liquid is converted into hot steam. The interception crystallization plate 224 is used to intercept the liquid and guide the supersaturated solution to condense, thereby achieving full desalination of the salt solution.

[0069] S5. Membrane filtration and washing: The condensed water vapor and low-salt salt solution discharged from the outside are separated and filtered through the RO membrane, thereby fully separating the water and inorganic matter. The organic detergent is used to wash with more water to separate the dissolved organic matter and achieve full purification of the salt solution.

The centrifugal processing frame 305 is rotatably installed on the inner side of the centrifugal operation barrel 303, and the separation interception net 307 is slidably installed on the inner side of the centrifugal operation barrel 303 to achieve steady interception and separation processing, ensuring the stability and speed of slag cleaning. The top of the separation interception net 307 is connected to the extraction linkage pipe 308;

[0093] A coarse screen plate 309 is installed in the middle of the inner side of the multi-division integration box 301, a fine screen plate 310 is installed at the bottom of the inner side of the multi-division integration box 301, and an external separation pipe 311 is connected through the inner side of the multi-division integration box 301;

[0094] A liquid injection treatment pump 312 is installed at the top of the multi-division integration box 301 and the top of the centrifugal operation barrel 303 through a motor base. The extraction linkage pipe 308 and the external separation pipe 311 are both installed through one end of the relay preheating box 220. One end of the extraction linkage pipe 308 and one end of the external separation pipe 311 are connected to one end of the liquid injection treatment pump 312 through an adapter to achieve steady liquid discharge processing and improve the filtration recovery rate of the salt solution. An operating solenoid valve 313 is embedded at one end of the series slag discharge pipe 302;

[0095] For stable operation of the device, the input ends of the centrifugal motor 304 , the separation electric push rod 306 , the liquid injection treatment pump 312 and the operating electromagnetic valve 313 are all electrically connected to the output end of the external controller.

[0096] The working principle and use process of the present invention are as follows: when treating high-salt water, the staff injects the high-salt water into the middle of the multi-barrel mixing frame 204 in the reaction interception barrel 202 through the external pumping equipment and the feeding separation pipe 209, and continuously adds water. During the high-salt water injection process, the feeding separation pipe 209 located in the middle is opened by the electromagnetic control valve 233, and the lime slurry is added to the high-salt water. At this time, the stirring motor 207 drives the stirring operation frame 208 to rotate, and the transposition motor 203 drives the multi-barrel mixing frame 204 to rotate, continuously changing its feeding position, achieving uniform distribution of raw materials, ensuring sufficient reaction contact, and mixing the high-salt water with the lime slurry;

[0097] When the lime slurry contacts the high salt water, the calcium bicarbonate and free carbonic acid in the high salt water contact and react with the calcium hydroxide in the lime slurry to generate calcium carbonate precipitation, thereby achieving partial decalcification and partial deacidification of the water. The calcium carbonate precipitates to the middle inner side of the multi-barrel mixing rack 204. At the same time, the magnesium bicarbonate in the high salt water reacts with the calcium hydroxide in the lime slurry to first generate magnesium carbonate. The magnesium carbonate is hydrolyzed and reacts again with the calcium hydroxide to generate magnesium hydroxide and calcium carbonate precipitation. The non-carbonate magnesium ions react with the calcium hydroxide to generate magnesium hydroxide and calcium compounds, wherein the magnesium hydroxide precipitates to achieve demagnesization. At this time, the magnesium hydroxide generated by the reaction reacts with the silicic acid in the high salt water, thereby removing part of the silicic acid and achieving secondary deacidification.

[0098] The high-salt water flows along the multi-net pressing frame 206 to the second layer of the multi-barrel mixing frame 204. At this time, soda ash is added through the feeding separation pipe 209. The soda ash reacts with non-carbonate calcium such as calcium sulfate and calcium chloride in the high-salt water to generate calcium carbonate precipitation, thereby achieving secondary decalcification treatment. The high-salt water after secondary treatment continues to flow along the multi-net pressing frame 206 to the third layer of the multi-barrel mixing frame 204. At this time, magnesium sulfate solution is added into the interior. The magnesium sulfate reacts with the silicic acid and the remaining calcium hydroxide therein to achieve deacidification and decalcification treatment, and the pH value of the high-salt water is controlled at 7. Through the three-stage reaction treatment, some precipitable inorganic substances in the high-salt water are separated;

[0099] The high salt water after preliminary treatment is extracted from the reaction interception barrel 202 through the extraction operation pump 231 and the series discharge pipe 217. The high salt water impacts the flocculant in the pressure separation grid 216 and injects it into the inner side of the mixing flocculation barrel 210. The mixing motor 213 drives the mixing stirring frame 214 to rotate along the mixing flocculation barrel 210, pushing the high salt water to rotate. At this time, the pressure separation electric push rod 215 drives the pressure separation grid 216 to move down into the high salt water. Through continuous rotation and punching, the flocculant and the high salt water are mixed. When the flocculant is mixed, the flocculant is mixed. After the combination is completed, the high-salt water is injected into the inner side of the centrifugal operation barrel 303 through the extraction operation pump 231 and the multiple rows of operation pipes 218, and the discharge position is controlled by operating the electromagnetic valve 313. During the liquid inlet process, the centrifugal motor 304 drives the centrifugal processing frame 305 to rotate slowly, and the centrifugal processing frame 305 promotes the flocculant to be fully mixed with the high-salt water. After stirring for a period of time, the centrifugal motor 304 drives the centrifugal processing frame 305 to rotate at a high speed. At this time, the suspended matter adsorbed by the flocculant in the high-salt water is centrifugally separated from the high-salt water.

[0100] After centrifugation is completed, the separation interception net 307 is driven downward by the separation electric push rod 306 to push the flocculants downward. At this time, the liquid injection treatment pump 312 and the extraction linkage pipe 308 extract the supernatant in the centrifugal operation barrel 303 and inject the supernatant into the inside of the relay preheating box 220. The series slag discharge pipe 302 is opened by operating the solenoid valve 313 to discharge the lower turbid liquid in the centrifugal operation barrel 303 into the multi-division integration box 301. At this time, the lower turbid liquid is intercepted by the coarse interception plate 309 and the fine mesh plate 310 and separated from the high brine. The high brine flows to the bottom of the inner side of the multi-division integration box 301, is extracted by the external separation pipe 311 and the liquid injection treatment pump 312, and is injected into the inside of the relay preheating box 220, so as to clean the suspended matter inside the high brine and perform secondary purification treatment on it to improve the purity and cleanliness of the high brine.

[0101] The high salt water in the relay preheating tank 220 is extracted through the extraction operation pipe 230 and the extraction operation pump 231, and is injected into the inside of the pressurized heating barrel 221. At this time, the pressure in the pressurized heating barrel 221 is increased through the inlet and outlet control pipe 225 and the pressure control air pump 228, and the pressure in the step-down electric heating tank 222 is reduced. The boiling point of the water is increased by the high pressure. After reaching the required temperature, the high-temperature high-salt water is injected into the inside of the step-down electric heating tank 222 through the extraction operation pump 231 and the extraction linkage pipe 229. At this time, the high-temperature high-salt water has a lower boiling point under the action of the low-pressure environment, generating a large amount of hot steam. The hot steam rises along the top of the raised positioning strip 223 to intercept the crystallization plate 224, and is discharged into the inside of the replacement interception box 219 through the exhaust operation pipe 226. When the hot steam enters the replacement interception box 219 2. When the steam is condensed, the high-salt water in the preheating tank 220 is heated to 100 ℃ and the high-salt water in the preheating tank 220 is heated to 100 ℃. The high-salt water in the preheating tank 2 ... and the high-salt water in the preheating tank 220 is heated to 100 ℃ and the high-salt water in the preheating tank 220 is heated to 100 ℃.

[0102] When cleaning the equipment, the multi-net pressing frame 206 is lifted up by the pressing electric push rod 205, the closing electric push rod 211 drives the closing operation frame 212 to rise, and the rotation motor 201 drives the reaction interception barrel 202 and the mixing flocculation barrel 210 to rotate, pouring out the impurities in the multi-barrel mixing frame 204 and the mixing flocculation barrel 210, and cooperating with the external flushing equipment to perform flushing treatment to achieve rapid cleaning treatment, and opening the step-down electric heating box 222 by closing the sealing cover 234, extracting the internal crystals and the remaining high brine through the external cleaning equipment, and replacing the intercepting crystallization plate 224 to achieve rapid material extraction and cleaning treatment.
