Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and specifically to an intelligent sewage treatment device for high-concentration saline wastewater. Background Art

[0002] Wastewater generated in the chemical industry usually contains a large amount of inorganic salts, and this kind of wastewater is also called high-salt concentrated water or high-concentration salt wastewater. One method for treating high-salt concentrated water is the low-temperature evaporation method, that is, boiling the wastewater at a relatively low temperature and converting the water therein into steam. After treatment by low-temperature evaporation, the high-salt concentrated water will form concentrated brine, and next, these concentrated brines need to undergo further crystallization treatment.

[0003] Existing high-salt concentrated water treatment devices usually use heaters to heat the wastewater, and reduce the pressure inside the kettle body through a vacuum pump, so that the wastewater starts to boil and evaporate at a low temperature. During the evaporation process, the vacuum pump maintains a low-pressure state inside the kettle body and extracts water vapor. However, during the wastewater heating stage, the wastewater in the middle of the kettle body is difficult to effectively contact with the heaters located on the side walls, which results in uneven heating of the wastewater, reduces the heating efficiency, and thus affects the overall treatment efficiency.

[0004] Therefore, those skilled in the art propose an intelligent sewage treatment device for high-concentration saline wastewater to solve the above problems. Summary of the Invention

[0009] Preferably, an air inlet pipe is communicated with the outer side of the fixed cylinder, one-way valves are installed on the inner sides of the air inlet pipe and the first communication pipe, and the conduction directions of the two one-way valves are opposite.

[0010] Preferably, one end of the second communication pipe penetrates through the outer wall of the outer housing and extends into the heating chamber, and one end of the third communication pipe penetrates through the cavity of the driving shaft and is fixedly connected with an annular air diffuser pipe.

[0015] The present invention provides an intelligent sewage treatment device for high-concentration saline wastewater. It has the following beneficial effects:

[0016] 1. In the present invention, on the one hand, the formed hot air flow enters the heating chambers of the outer tank body and the inner tank body, improving the comprehensiveness and uniformity of heating. On the other hand, it enters the inner tank body through the annular air diffuser pipe, enhancing the heat exchange effect of the wastewater and effectively improving the heat conduction efficiency of the heating area.

[0017] 2. By arranging the annular aeration pipe near the inner bottom of the inner shell, the present invention effectively agitates and suspends the flocculant deposited at the bottom of the wastewater by using the generated airflow, significantly improving the distribution uniformity and activity of the flocculant. In traditional wastewater treatment methods, the flocculant often precipitates at the bottom of the wastewater due to gravity, resulting in poor flocculation effect and affecting the sewage treatment efficiency. However, the airflow generated by the annular aeration pipe of the present invention can not only avoid the deposition of the flocculant, but also promote its full contact with the pollutants in the wastewater, thereby improving the sewage treatment effect of the saline wastewater.

[0018] 3. By using the mutual cooperation of additional structures such as elastic telescopic rods, connecting rods, and sensors, the present invention can automatically detect in real time whether the saline wastewater inside the reaction kettle has been treated. Through this intelligent control, the automation level and treatment efficiency of the system are greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0028] Please refer to the attached Figure 1 -attached Figure 7 , for the intelligent sewage treatment device for high-concentration saline wastewater in the embodiment of the present invention, it includes an outer housing 1. An inner housing 2 is slidably installed inside the outer housing 1. A heating chamber is provided between the outer housing 1 and the inner housing 2. The inner side of the outer housing 1 is movably connected to a drive shaft 501 through a bearing. A spline shaft 502 is fixedly connected to the end of the drive shaft 501. A spline sleeve 503 is slidably connected to the outside of the spline shaft 502. Two mixing plates 504 are fixedly connected to the outside of the spline sleeve 503. A plurality of flow guide grooves 505 are formed inside the mixing plates 504. One side of the bottom end of the outer housing 1 is fixedly connected to a fixed cylinder 506. A movable rod 507 is slidably connected inside the fixed cylinder 506. A first connecting pipe 508 is communicated with one side of the outer surface of the fixed cylinder 506. A heater 509 is fixedly connected to the outside of the outer housing 1. A second connecting pipe 510 is installed at the top of the heater 509. A third connecting pipe 511 is installed at the bottom of the heater 509. An air inlet pipe is communicated with the outside of the fixed cylinder 506. Check valves are installed inside both the air inlet pipe and the first connecting pipe 508, and the conduction directions of the two check valves are opposite.

[0029] Specifically, the outer housing 1 is the external structure of the device, providing physical protection and support. It surrounds the entire heating and stirring system. The inner housing 2 is a sliding component installed inside the outer housing 1, and its main function is to provide space for the heating chamber. The heating chamber is used to store heating gas and conduct heat, and heat the wastewater through heat exchange with the outer wall of the inner housing 2. The heater 509 is the main heating device outside the outer housing 1. It provides a heat source to heat the air flow, which is transported to the heating chamber through pipes. The design of the heater 509 can ensure effective heat transfer to the heating air flow and improve the efficiency of wastewater treatment.

[0030] The spline shaft 502 is slidably connected to the spline sleeve 503 to ensure that the spline sleeve 503 can move freely on the shaft, so as to transmit power to the stirring device. The mixing plates 504 are the stirring devices connected to the outside of the spline sleeve 503. Each mixing plate 504 is provided with a plurality of flow guide grooves 505, which are used to enhance the contact effect between the wastewater and the air flow, improve the stirring effect of the wastewater, and accelerate evaporation. This design continuously stirs the high-salt wastewater, making the wastewater liquid level always in a moving state. This stirring helps to evaporate water and improve the heat exchange efficiency when the wastewater is heated.

[0031] The fixed cylinder 506 is a component related to air flow control in the device. An intake pipe is connected to its outer surface, and a one-way valve is installed inside the intake pipe and the first connecting pipe 508. The movable rod 507 slides inside the fixed cylinder 506 to control the opening and closing of the gas flow path. When the movable rod 507 moves, it controls the opening and closing of the one-way valve connected to the intake pipe. Through the position change of the movable rod 507, the flow direction of the air flow is controlled to ensure that the gas can smoothly enter the heater 509. The hot air flow generated by the heater 509 enters the second connecting pipe 510 and the third connecting pipe 511 through the pipeline, and the hot air flow is respectively sent into the heating chamber and the annular aeration pipe. The second connecting pipe 510 guides the hot air flow to the heating chamber, and further exchanges heat with the outer wall of the inner housing 2 through the heating chamber to increase the temperature of the wastewater. The third connecting pipe 511 discharges a part of the hot air flow, passes through the annular aeration pipe, and is sprayed into the high-salt wastewater through the nozzle. In this way, the hot air flow is in direct contact with the wastewater, effectively improving the evaporation efficiency of the wastewater. Two one-way valves are installed in the intake pipe and the first connecting pipe 508, and their conduction directions are opposite. The purpose of this design is to ensure that the air flow only flows in one direction under the control of the movable rod 507, avoiding the reverse flow of the air flow, so as to ensure the correct delivery of the heating gas.

[0032] In addition, during the process of injecting the flocculant and the high-concentration saline wastewater into the outer housing 1, due to the buoyancy of the high-salt wastewater, the spline sleeve 503 always remains above the wastewater liquid level. As the high-salt wastewater evaporates, the liquid level of the wastewater gradually decreases. In order to ensure that the evaporation rate of the water vapor is effectively increased during this process, the system adopts corresponding mechanical designs. When the first gear 601 starts to rotate, it drives the second gear 602 to rotate coaxially. The rotation of the second gear 602 further drives the connected drive shaft 501 to rotate. Through the rotation of the drive shaft 501, the power of the entire transmission system is transmitted to the spline shaft 502, and then the spline sleeve 503 is pushed to operate. During this process, the cooperation between the spline shaft 502 and the spline sleeve 503 not only ensures the stable transmission of the driving force, but also drives the mixing plate 504 to rotate. The rotation of the mixing plate 504 continuously stirs the high-salt wastewater liquid level. This stirring effect ensures that the liquid level area is continuously stirred, thereby accelerating the contact between the high-salt wastewater and the air and improving the evaporation efficiency of the water vapor.

[0033] A motor is installed at the bottom of the outer housing 1. The output end of the motor is fixedly connected with a third gear 603 and a first gear 601 in sequence. A second gear 602 is fixedly connected to the outside of the drive shaft 501. A drive rack 604 is slidably installed on one side of the bottom end of the outer housing 1. The outside of the drive rack 604 is meshed with the outside of the third gear 603, the outside of the first gear 601 is meshed with the outside of the second gear 602, and one side of the drive rack 604 is fixedly connected to one end of the movable rod 507.

[0034] Specifically, by starting the motor to drive the gear three 603 and the gear one 601 to rotate reciprocally, with the reciprocal rotation of the gear three 603, the driving rack 604 will be driven to rotate reciprocally, and at this time, the movable rod 507 will be driven to reciprocally move along the inner wall of the fixed cylinder 506.

[0035] One end of the connecting pipe two 510 penetrates through the outer wall of the outer housing 1 and extends into the heating chamber, and one end of the connecting pipe three 511 penetrates through the cavity of the driving shaft 501 and is fixedly connected with an annular aeration pipe.

[0036] Specifically, the heated hot air is transported to the heating chamber through the connecting pipe two 510 for heating, and the hot air flow is transported in the annular aeration pipe through the connecting pipe three 511.

[0037] A plurality of elastic telescopic rods 401 are fixedly connected to the outside of the outer housing 1 at equal intervals. The telescopic ends of the elastic telescopic rods 401 are fixedly connected with connecting rods 402. The ends of the connecting rods 402 penetrate through the bottom of the outer housing 1 and are fixedly connected with the bottom of the inner housing 2. Sensors 403 are installed on both the inner top wall and the inner bottom wall of the outer housing 1.

[0038] Specifically, an appropriate amount of flocculant and high-concentration saline wastewater are introduced into the inner housing 2 through the liquid inlet pipe 3. When the wastewater in the inner housing 2 is full, the inner housing 2 moves downward under the action of gravity. At this time, the bottom of the inner housing 2 will contact the sensor 403 located on the inner bottom wall of the outer housing 1, sending a signal to the external control device to remind the staff that the high-concentration saline wastewater has been filled and the water supply should be stopped. When the evaporation treatment of the saline wastewater is completed, at this time, the inner housing 2 moves upward under the elastic force of the elastic telescopic rods 401 until the upper surface of the inner housing 2 can contact the sensor 403 located on the inner top wall of the outer housing 1 and sends a signal to the external control device again to remind the staff that the reaction of the high-concentration saline wastewater has been completed. In this way, through this intelligent control, the automation level and processing efficiency of the system are greatly improved.

[0039] The top of the outer housing 1 is detachably connected with a cover plate. The top of the cover plate is provided with a liquid inlet pipe 3. The bottom of the liquid inlet pipe 3 is communicated with the inside of the inner housing 2. The liquid inlet pipe 3 is used to transport the flocculant and high-concentration saline wastewater into the inner housing 2.

[0040] Specifically, the top of the outer shell 1 is equipped with a detachable cover plate, which facilitates the maintenance and cleaning of the device. A liquid inlet pipe 3 is installed on the top of the cover plate, and the bottom of the liquid inlet pipe 3 is directly connected to the inside of the inner shell 2. The function of the liquid inlet pipe 3 is to transport the flocculant and the high-concentration saline wastewater into the inner shell 2, thus starting the wastewater treatment process. Through the liquid inlet pipe 3, the flocculant and the wastewater can smoothly enter the inner shell 2, providing the necessary raw materials and liquids for the subsequent heating, stirring, and evaporation processes. This structural design not only ensures the effective transportation of the liquid but also enables the device to add and adjust materials more conveniently during operation.

[0041] An air extraction pipe 7 is connected to the bottom of the outer shell 1, and the air extraction pipe 7 is used to discharge the gases generated during the heat exchange reaction. An exhaust steam device is installed outside the inner shell 2, and the exhaust steam device is used to extract the steam generated during the evaporation process of the saline wastewater in the inner shell 2.

[0042] Specifically, in the present invention, an air extraction pipe 7 is provided at the bottom of the outer shell 1, and the function of the air extraction pipe 7 is to discharge the gases generated during the heat exchange reaction inside the device. The heat exchange reaction is accompanied by high temperature and gas generation. To maintain the stable operation of the system, the presence of the air extraction pipe 7 can effectively prevent the accumulation of gases, keep the air circulation inside the device, and help prevent unnecessary pressure increase or gas pollution. These gases are usually generated after heat exchange with the external environment through the heat exchanger. By using the air extraction pipe 7 to discharge these gases, the safety and stability during the reaction process can be effectively maintained. At the same time, an exhaust steam device is equipped outside the inner shell 2. The main function of the exhaust steam device is to extract the steam generated due to the evaporation process of the saline wastewater from the inside of the inner shell 2. During the heating process of the saline wastewater, the water will evaporate into steam, and these steams may affect the operation effect of the device or exchange heat with the environment in the system. Therefore, it is necessary to effectively extract them through the exhaust steam device. The extraction of steam can not only prevent the retention of waste gas and water vapor and ensure the continuous progress of the evaporation process but also improve the evaporation efficiency during the wastewater treatment process. By effectively discharging the steam, the system can maintain an appropriate internal temperature and pressure, thereby improving the operation efficiency and reliability of the device.

[0043] Working principle: When specifically using this device, it specifically includes the following steps:

[0044] Step 1: Pour an appropriate amount of flocculant and high-concentration saline wastewater into the interior of the inner housing 2 through the liquid inlet pipe 3. When the wastewater in the inner housing 2 is full, the inner housing 2 moves downward under the action of gravity. At this time, the bottom of the inner housing 2 will contact the sensor 403 on the inner bottom wall of the outer housing 1, sending a signal to the external control device to remind the staff that the high-concentration saline wastewater has been filled and the water supply should be stopped. At the same time, when the inner housing 2 moves downward, it will drive the connecting rod 402 to move synchronously and drive the elastic telescopic rod 401 to be in a stretched state;

[0045] Step 2: Start the motor to drive the gear three 603 and the gear one 601 to rotate reciprocally. As the gear three 603 rotates reciprocally, it will drive the driving rack 604 to rotate reciprocally. At this time, drive the movable rod 507 to reciprocally move along the inner wall of the fixed cylinder 506. When one end of the movable rod 507 moves along the direction of the connecting pipe one 508, the one-way valve of the intake pipe is closed, and the one-way valve at the connecting pipe one 508 is opened. At this time, the gas inside the fixed cylinder 506 is transported to the heater 509 through the connecting pipe one 508 for heating to generate hot air flow. On the one hand, the hot air flow enters the heating chamber between the outer housing 1 and the inner housing 2 through the connecting pipe two 510. On the other hand, it is discharged into the annular aeration pipe through the connecting pipe three 511, and the hot air flow is sprayed into the high-salt wastewater through the annular aeration pipe. In this way, after the hot air flow inside the heating chamber undergoes a heat exchange reaction with the outer wall of the inner housing 2, the temperature of the saline wastewater is evenly increased. The hot water that has experienced the heat exchange reaction is discharged through the suction pipe 7. At the same time, the hot air flow sprayed into the saline wastewater through the aeration pipe can enhance the heat exchange effect of the wastewater and effectively improve the heat conduction efficiency of the heating area;

[0046] Step 3: During the process of injecting flocculant and high-concentration saline wastewater into the interior of the outer housing 1 in Step 1, the spline sleeve 503 will always be located above the liquid level of the high-salt wastewater due to the buoyancy of the high-salt wastewater. During the evaporation process of the high-salt concentrated water, the high-salt wastewater will continuously move downward. At this time, as the gear one 601 rotates, it drives the gear two 602 to rotate coaxially. Through the rotation of the gear two 602, the drive shaft 501 is driven to rotate. In this way, under the transmission of the spline shaft 502 and the spline sleeve 503, the mixing plate 504 is driven to rotate, so that the liquid level of the high-salt concentrated water is always in a stirred state, thereby increasing the evaporation speed of water vapor from the liquid level of the high-salt concentrated water;

[0047] Step 4: While the aeration pipe sprays hot air flow into the high-salt wastewater, the generated air flow is used to effectively stir and suspend the flocculant deposited at the bottom of the wastewater, significantly improving the distribution uniformity and activity of the flocculant. At the same time, through the multiple diversion grooves 505 arranged outside the mixing plate 504, the fluidity of the high-salt wastewater inside the outer housing 1 can be enhanced, improving the treatment effect.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
