Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and in particular to an evaporative sewage purification device based on industrial wastewater. Background Art

[0002] Industrial wastewater refers to wastewater and waste liquid generated during industrial production, which contains industrial production materials, intermediate products, by-products and pollutants generated during the production process. Industrial wastewater evaporation treatment is an effective wastewater treatment method. It evaporates the water in the wastewater through evaporation technology, thereby concentrating or separating the dissolved solids in the wastewater. This method has obvious advantages in treating high-concentration organic wastewater, saline wastewater and toxic and hazardous wastewater.

[0003] However, since industrial wastewater contains harmful substances during its production process, when the wastewater is evaporated and purified, the harmful substances in the wastewater may evaporate along with the water vapor and dissolve in the condensed water, resulting in the presence of harmful components in the evaporated condensed water. When the condensed water is discharged or reused, it will affect the external environment and the reuse effect. Therefore, when evaporating the wastewater, it is necessary to test the water after the water vapor condenses. When the condensed water is detected to contain harmful components, it is necessary to add reagents to the evaporating wastewater to neutralize the harmful substances and avoid the presence of harmful components in the evaporated condensed water. However, the existing technology requires testing after evaporation, and during evaporation, all wastewater is directly evaporated, resulting in a large amount of energy consumed by the wastewater to generate water vapor when the wastewater evaporation and condensation water is tested, which is not conducive to rapid detection and causes energy waste. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing wastewater evaporation, which is to directly evaporate all wastewater, resulting in a large amount of energy consumed in generating water vapor from the wastewater during wastewater evaporation and condensation water detection, which is not conducive to rapid detection and causes energy waste, the present invention provides an evaporative sewage purification equipment based on industrial wastewater.

[0006] In addition, it is particularly preferred that it also includes a cleaning frame, a scraper, an electric annular guide rail and a moving block; the connecting frame is fixedly connected to two electric annular guide rails; each electric annular guide rail is fixedly connected to at least six moving blocks; all the moving blocks are commonly fixedly connected to the cleaning frame, the cleaning frame is located between two sealing frames, and the sealing frame is tightly attached to the cleaning frame; a feed port is provided on the cleaning frame; the cleaning frame is provided with a storage cavity; the feed port is connected to the storage cavity; a scraper is fixedly connected to the feed port of the cleaning frame, and the electric annular guide rail is connected to an external power supply.

[0007] In addition, it is particularly preferred that the contact area between the sealing frame and the inner wall of the outer water collection cavity is made of silicone material.

[0008] In addition, it is particularly preferred that it also includes an electric push rod and a block; the connecting frame is fixedly connected to an electric push rod; each telescopic part of the electric push rod is fixedly connected to a block; each block is located directly above the corresponding feed port.

[0009] Furthermore, it is particularly preferred that the bottom of the inner water-collecting cavity is higher than the bottom of the outer water-collecting cavity.

[0010] In addition, it is particularly preferred that an air outlet pipe is further included; the connecting frame is fixedly connected to the air outlet pipe; and the air outlet pipes are communicated with the material storage cavity.

[0011] In addition, it is particularly preferred that a liquid inlet pipe is further included; the connecting frame is fixedly connected with the liquid inlet pipe; and the liquid inlet pipe is communicated with the material storage cavity.

[0013] Furthermore, it is particularly preferred that the cleaning plate is arc-shaped.

[0014] In addition, it is particularly preferred that the cleaning plate is made of silicone.

[0015] Beneficial effects:

[0016] By discharging a small amount of wastewater into the outer water collection cavity, the small amount of wastewater can be preheated, thereby accelerating the heating speed, thereby quickly generating water vapor, and quickly testing the water vapor. After the test, if it fails again and needs to be heated repeatedly, due to the small amount of wastewater in the outer water collection cavity, a small amount of wastewater can be heated with a small amount of energy, thereby avoiding the problem of energy waste caused by repeated heating of all the wastewater.

[0017] Since the water vapor generated by the wastewater will be discharged to the external collection equipment through the air outlet cavity of the sealing frame, the water vapor will dry the impurities in the storage cavity through the sealing frame and the cleaning frame, making the impurities in the wet state dry. The dried impurities are easier to carry out subsequent treatment, such as incineration, landfill or resource recycling, thereby reducing the subsequent drying steps and saving energy.

[0018] By connecting the wastewater in the inner water collection cavity and discharging the impurities evaporated and precipitated into the outer water collection cavity, the impurities in the inner water collection cavity can be cleaned while the wastewater is evaporated. There is no need to perform additional cleaning work after the wastewater in the inner and outer water collection cavities has evaporated, thereby optimizing the cleaning process.

[0019] The water vapor circulating through the air outlet cavity heats and evaporates a small amount of subsequent batches of wastewater discharged into the storage cavity, so that while the evaporation detection of the previous batch of wastewater is being carried out, the evaporation detection of the subsequent batch of wastewater can also be carried out, thereby avoiding energy waste of wastewater, and when the subsequent batches of wastewater are not completely purified, they can also be processed in advance, thereby accelerating the wastewater purification efficiency.

[0031] The drive assembly includes a fixed frame 101, an electric multi-stage telescopic rod 1 102 and an electric multi-stage telescopic rod 2 103; the water storage cylinder 1 is fixedly connected to the fixed frame 101; the fixed frame 101 is fixedly connected to four electric multi-stage telescopic rods 1 102; the telescopic parts of all electric multi-stage telescopic rods 1 102 are commonly fixedly connected to the connecting frame 4; the fixed frame 101 is fixedly connected to four electric multi-stage telescopic rods 2 103; the telescopic parts of all electric multi-stage telescopic rods 2 103 are commonly fixedly connected to the connecting frame 6.

[0032] It also includes a cleaning frame 111, a scraper 114, an electric annular guide rail 115 and a moving block 117; the connecting frame 6 is fixedly connected to two electric annular guide rails 115; each electric annular guide rail 115 is fixedly connected to six moving blocks 117; all the moving blocks 117 are commonly fixedly connected to the cleaning frame 111, the cleaning frame 111 is located between the two sealing frames 7, and the sealing frame 7 is in close contact with the cleaning frame 111; a feed port 11101 is provided on the cleaning frame 111; the cleaning frame 111 is provided with a material storage cavity 11102; the feed port 11101 is communicated with the material storage cavity 11102; a scraper 114 is fixedly connected to the feed port 11101 of the cleaning frame 111, and the electric annular guide rail 115 is connected to an external power supply.

[0033] The contact area between the sealing frame 7 and the inner wall of the outer water collection cavity 1003 is made of silicone material, which ensures the sealing between the sealing frame 7 and the inner wall of the outer water collection cavity 1003.

[0034] It also includes an electric push rod 112 and a stopper 113; the connecting frame 6 is fixedly connected to an electric push rod 112; each telescopic part of the electric push rod 112 is fixedly connected to a stopper 113; each stopper 113 is located directly above the corresponding feed port 11101.

[0035] The bottom of the inner water collection cavity 1001 is higher than the bottom of the outer water collection cavity 1003 , thereby facilitating the discharge of wastewater in the inner water collection cavity 1001 into the outer water collection cavity 1003 .

[0036] It also includes an air outlet pipe 116; the connecting frame 6 is fixedly connected to the air outlet pipe 116; the air outlet pipe 116 is communicated with the material storage cavity 11102, and the water vapor generated in the material storage cavity 11102 is discharged through the air outlet pipe 116.

[0037] The specific working steps are:

[0038] The external liquid delivery device is connected to the water inlet pipe 2, and the external liquid delivery device transports waste water; the exhaust hole 5001, the air outlet cavity 7001 and the air outlet pipe 116 are respectively connected to the same external collection device, and the generated water vapor is sucked away by the external collection device and condensed into water.

[0039] When wastewater evaporation treatment is required, the wastewater is discharged into the inner water collecting cavity 1001 of the water storage cylinder 1 through the external liquid feeding equipment and the water inlet pipe 2. At this time, since the inner water collecting cavity 1001 and the outer water collecting cavity 1003 are connected through the connecting hole 1002, the discharged water will also enter the outer water collecting cavity 1003. When the water level sensor detects that the water level of the incoming wastewater is about to contact the lower surface of the wastewater of the scraper plate 5, the external liquid feeding equipment stops the wastewater feeding connecting hole 1002 and closes the electric control valve 3, so that the inner water collecting cavity 1001 and the outer water collecting cavity 1003 are no longer connected, and then the external heating device heats the wastewater in the outer water collecting cavity 1003 of the water storage cylinder 1. At this time, since the outer water collecting cavity 1003 is connected The wastewater in the outer water collection cavity 1003 is close to the external heating device, and the wastewater content in the outer water collection cavity 1003 is small, so that the wastewater in the outer water collection cavity 1003 is quickly heated, and then water vapor is quickly generated. The water vapor and gas generated by the wastewater will be discharged from the air outlet cavity 7001 to the external collection device, and then condensed through the external collection device, and then the condensed water is manually sent to the detection device to detect the condensed water. When the test result of the condensed water is qualified, the evaporation treatment work can be continued. When the test result is unqualified, the air outlet cavity 7001 and the exhaust hole 5001 are no longer connected to the external collection device through manual operation, and then the air outlet cavity 7001 and the exhaust hole 5001 are respectively connected to different external liquid delivery devices, and then The chemicals are respectively delivered into the inner water collection cavity 1001 and the outer water collection cavity 1003 according to the contents of the wastewater therein through the external liquid delivery equipment, so that the wastewater in the inner water collection cavity 1001 and the outer water collection cavity 1003 are purified respectively. It should be noted that different dosages of chemicals are added according to the different contents of wastewater in the inner water collection cavity 1001 and the outer water collection cavity 1003, so as to avoid the situation where the wastewater in the outer water collection cavity 1003 is qualified while the wastewater in the inner water collection cavity 1001 is unqualified after the addition of chemicals. Then the external heating equipment is used to heat it again, and the wastewater in the outer water collection cavity 1003 can be tested again. When the test result is qualified , reconnect the air outlet cavity 7001 and the exhaust hole 5001 to the external collection device to continue the evaporation work. When the test result is unqualified, the inner water collection cavity 1001 and the outer water collection cavity 1003 can be repeatedly added with reagents until the test result meets the standard. In this way, by discharging a small amount of wastewater into the outer water collection cavity 1003, a small amount of wastewater can be preheated, thereby accelerating the heating speed, thereby quickly generating water vapor, and quickly testing the water vapor. After the test, if it fails again and needs to be heated repeatedly, due to the small amount of wastewater in the outer water collection cavity 1003, a small amount of wastewater can be heated with a small amount of energy, thereby avoiding the problem of energy waste caused by repeated heating of all the wastewater.

[0040] It should be noted that when the water in the outer water collection cavity 1003 has evaporated, the water level sensor controls the electric control valve 3 to open again, so that the wastewater in the inner water collection cavity 1001 flows into the outer water collection cavity 1003 again for evaporation operation, and as the heating time becomes longer, the wastewater in the inner water collection cavity 1001 will also be evaporated. At this time, the water vapor generated in the inner water collection cavity 1001 will be discharged to the external collection device through the exhaust hole 5001, and then the water vapor condensation work will be carried out.

[0041] When the wastewater is being evaporated, it contains impurities. After the wastewater evaporates, the impurities will adhere to the inner wall of the water storage cylinder 1, while the wastewater in the outer water collection cavity 1003, which has a small amount of wastewater, will be evaporated first. Therefore, when the wastewater in the outer water collection cavity 1003 is evaporated, the electric multi-stage telescopic rod 2 103 drives the connecting frame 6, the sealing frame 7, the cleaning frame 111, the electric push rod 112, the block 113, the scraper 114, the electric annular guide rail 115, the air outlet pipe 116 to descend and the moving block 117. During the descent, the sealing frame 7 will adhere to the outer water collection cavity. The impurities on the inner wall of the cavity 1003 are scraped off, and the scraped impurities will fall on the electric annular guide rail 115 at the bottom of the outer water collection cavity 1003. When the scraper 114 contacts the bottom of the outer water collection cavity 1003, the electric multi-stage telescopic rod 103 stops, and the electric annular guide rail 115 drives the moving block 117 to drive the cleaning frame 111 to rotate clockwise from a top-down perspective, so that the impurities pass through the scraper 114 and the feed port 11101 into the storage cavity 11102, thereby completing the cleaning and collection of the impurities; then the electric control valve 3 is opened to clear the inner water collection cavity 1003. 01 is discharged into the outer water collection cavity 1003, and then the evaporation work is continued. At the same time, the electric multi-stage telescopic rod 103 drives the connecting frame 6, the sealing frame 7 and the cleaning frame 111 and other parts to rise back to their original positions. When the connecting frame 6 and other parts rise, the electric push rod 112 pushes the stopper 113 down to contact the bottom of the storage cavity 11102, so that the stopper 113 blocks the feed port 11101, making the storage cavity 11102 a sealed space, preventing the water vapor generated in the outer water collection cavity 1003 from entering the storage cavity 11102 and being absorbed by impurities. And avoid the discharge of impurities, and then continue to evaporate the wastewater. The water vapor generated by the wastewater will be discharged to the external collection equipment through the air outlet cavity 7001 of the sealing frame 7. At this time, the water vapor will pass through the sealing frame 7 and the cleaning frame 111 to dry the impurities in the storage cavity 11102, so that the impurities in the wet state become dry, and the dried impurities are easier to carry out subsequent treatment, such as incineration, landfill or resource recycling, thereby reducing the subsequent drying steps and saving energy. The water vapor generated by the drying of the impurities will be discharged from the air outlet pipe 116 to the external collection equipment.

[0042] When the wastewater in the outer water collection cavity 1003 is completely evaporated, the wastewater in the inner water collection cavity 1001 is also partially evaporated, the wastewater level in the inner water collection cavity 1001 is reduced, and impurities are attached to the wall surface after the water level is reduced. Therefore, while the electric multi-stage telescopic rod 2 103 drives the connecting frame 6, the sealing frame 7 and the cleaning frame 111 to descend to clean the impurities on the inner wall of the outer water collection cavity 1003, the electric multi-stage telescopic rod 1 102 will drive the connecting frame 4 and the scraper 5 to descend. The scraper 5 will clean the impurities on the wall surface after the water level in the inner water collection cavity 1001 is reduced. The impurities on the wall are scraped off, and the impurities scraped off by the scraper plate 5 will fall back into the wastewater in the inner water collection cavity 1001, and will be discharged into the outer water collection cavity 1003 along with the opening of the electric control valve 3. When the wastewater in the inner water collection cavity 1001 is discharged into the outer water collection cavity 1003 for evaporation, the water level of the wastewater in the inner water collection cavity 1001 is further reduced, that is, when the wastewater in the inner water collection cavity 1001 is discharged into the outer water collection cavity 1003 for evaporation, the electric multi-stage telescopic rod 102 synchronously drives the connecting frame 4 and the scraper plate 5 to descend to the inner layer. After the water level in the inner water collection cavity 1001 drops, the impurities on the wall are scraped off, so that the scraper plate 5 always maintains the initial distance from the wastewater surface in the inner water collection cavity 1001, that is, the water level of the wastewater is close to the lower surface of the scraper plate 5, and this process is repeated until all the wastewater in the inner water collection cavity 1001 is discharged into the outer water collection cavity 1003. Each time the wastewater in the outer water collection cavity 1003 is completely evaporated, the electric multi-stage telescopic rod 103 drives the connecting frame 6, the sealing frame 7 and the cleaning frame 111 to descend to clean the impurities on the inner wall of the outer water collection cavity 1003. For cleaning, the electric multi-stage telescopic rod 102 will drive the connecting frame 4 and the scraper plate 5 to descend and scrape off the impurities on the wall after the water level in the inner water collection cavity 1001 drops. In this way, the wastewater in the inner water collection cavity 1001 is connected and the impurities evaporated and precipitated are discharged into the outer water collection cavity 1003. While the wastewater is being evaporated, the impurities in the inner water collection cavity 1001 are cleaned. There is no need to perform additional cleaning work after the wastewater in the inner water collection cavity 1001 and the outer water collection cavity 1003 are evaporated, which optimizes the cleaning process.

[0043] It should be noted that since the bottom of the outer water collection cavity 1003 is lower than the bottom of the inner water collection cavity 1001, it ensures that during the evaporation cleaning process, the remaining wastewater in the inner water collection cavity 1001 can be smoothly discharged into the outer water collection cavity 1003; and when all the wastewater in the inner water collection cavity 1001 is discharged into the outer water collection cavity 1003, the wastewater can be transported to the inner water collection cavity 1001 again, thereby improving the continuity of the evaporation treatment of different batches of wastewater through the setting of the inner water collection cavity 1001 and the outer water collection cavity 1003.

[0044] When it is necessary to clean the impurities in the storage cavity 11102, the electric multi-stage telescopic rod 103 can continue to drive the connecting frame 6 and the cleaning frame 111 and other parts to rise, and then place the collection box under the cleaning frame 111, and then directly rotate the cleaning frame 111. When the cleaning frame 111 rotates, the stopper 113 remains in position unchanged, so that when the cleaning frame 111 rotates, the stopper 113 is stationary relative to the inner wall of the storage cavity 11102, and then the stopper 113 blocks the impurities and scrapes them off. As the cleaning frame 111 rotates, the impurities will be discharged through the feed port 11101 to the placed collection box, thereby completing the impurity discharge work.

[0045] When the wastewater in the inner water collection cavity 1001 is completely discharged into the outer water collection cavity 1003 for evaporation, and the inner water collection cavity 1001 re-transports another batch of wastewater for evaporation, when the wastewater in the outer water collection cavity 1003 is about to evaporate completely, the wastewater connection frame 4 can monitor the wastewater level in the outer water collection cavity 1003 through the water level sensor, and the cleaning frame 111 can be lowered to the outer water collection cavity 1003 through the electric multi-stage telescopic rod 103. 003 inner wall impurities are scraped off, and at this time, part of the wastewater remaining in the outer water collection cavity 1003 will also enter the storage cavity 11102. It should be noted that after the wastewater remaining in the outer water collection cavity 1003 enters the storage cavity 11102, the electric push rod 112 pushes the stopper 113 down to contact the bottom of the storage cavity 11102, so that the stopper 113 blocks the feed port 11101, and then the electric multi-stage telescopic rod 103 drives The cleaning frame 111 rises and resets. At this time, the cleaning frame 111 places the impurities on the inner wall of the outer water collection cavity 1003 and the remaining wastewater in the outer water collection cavity 1003 in the storage cavity 11102, and then opens the electric control valve 3, and another batch of wastewater transported to the inner water collection cavity 1001 will enter the outer water collection cavity 1003. At this time, the water vapor generated by the evaporation of another batch of wastewater into the outer water collection cavity 1003 will heat and dry the remaining wastewater and impurities collected in the storage cavity 11102. In this way, it is avoided that when cleaning the impurities in the outer water collection cavity 1003, the wastewater in the outer water collection cavity 1003 needs to be evaporated before the impurity cleaning work is carried out, resulting in the evaporation time being too long and the subsequent wastewater cannot be evaporated quickly. This further improves the continuity of the wastewater evaporation treatment, and also makes full use of the heat generated by the water vapor generated by the evaporation of wastewater.

[0046] Example 2

[0047] On the basis of Example 1, Figure 2 、 Figure 3 、 Figure 5 and Figure 6As shown, a liquid inlet pipe 201 is also included; the connecting frame 6 is fixedly connected to the liquid inlet pipe 201; the liquid inlet pipe 201 is communicated with the material storage cavity 11102.

[0048] It also includes a motor 211 and a cleaning plate 212; the connecting frame 4 is fixedly connected to the motor 211; the output shaft of the motor 211 is fixedly connected to the cleaning plate 212; the lower part of the scraper plate 5 is in close contact with the cleaning plate 212, and the impurities remaining in the inner water collection cavity 1001 are scraped into the outer water collection cavity 1003 through the cleaning plate 212.

[0049] The cleaning plate 212 is arc-shaped, which makes it easier for the cleaning plate 212 to scrape the impurities remaining in the inner water collection cavity 1001 into the outer water collection cavity 1003 .

[0050] The cleaning plate 212 is made of silicone, so that when the cleaning plate 212 rotates to scrape off impurities, it can be in close contact with the inner wall of the inner water collection cavity 1001, thereby facilitating the scraping of impurities in dead corners, and it is not easy for the cleaning plate 212 to rub against the inner wall of the inner water collection cavity 1001 when in contact, causing wear.

[0051] The specific working steps are:

[0052] The external liquid delivery device is connected to the liquid inlet pipe 201, and the external liquid delivery device delivers wastewater.

[0053] On the basis of the evaporation detection in Example 1, the external liquid delivery device can deliver a small amount of wastewater of subsequent batches to the liquid inlet pipe 201, and then deliver it into the storage cavity 11102 through the liquid inlet pipe 201. It should be noted that at this time, the electric push rod 112 pushes the block 113 down to contact the bottom of the storage cavity 11102, and the storage cavity 11102 is in a sealed state. At this time, the water vapor circulating through the air outlet cavity 7001 heats and evaporates the small amount of wastewater of subsequent batches discharged into the storage cavity 11102, so that while the evaporation detection of the previous batch of wastewater is being carried out, the evaporation detection of the subsequent batch of wastewater can also be carried out, thereby avoiding energy waste of wastewater, and when the subsequent batch of wastewater is not completely purified, it can also be processed in advance, thereby speeding up the wastewater purification efficiency.

[0054] When all the remaining wastewater in the inner water collection cavity 1001 is discharged into the outer water collection cavity 1003, the scraper plate 5 can play a scraping role, but some impurities are attached to the bottom of the inner water collection cavity 1001, so at this time the motor 211 will drive the cleaning plate 212 to rotate, so that the cleaning plate 212 scrapes off the impurities attached to the bottom of the outer water collection cavity 1003, so that the impurities are driven to the outer water collection cavity 1003 by the flowing wastewater.

[0055] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
