Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, and more specifically, to a chemical wastewater reuse treatment system with low caking rate. Background Technology

[0002] Chemical plants are major water users, typically consuming millions of cubic meters of fresh water annually, resulting in a low rate of water reuse.

[0003] To maintain sustainable development, reduce water waste, lower production costs, and improve economic and social benefits, chemical wastewater needs to undergo advanced treatment (tertiary treatment) to serve as makeup water for circulating water or desalination, achieving wastewater reuse. Since the impurities in the water requiring advanced treatment are mainly suspended particles and fine fibers, mechanical filtration is mostly used to remove these impurities, thus achieving the goal of recycling and reusing chemical wastewater. To avoid clogging and caking of the filter plates...

[0004] Most existing technologies employ a backwashing process for filter plates to reduce clogging and extend their service life. However, continuous backwashing not only causes impact damage to the filter plates but also reduces the efficiency of deep industrial wastewater treatment, increases water resource consumption, reduces wastewater recycling rates, and hinders the development of chemical wastewater reuse. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the present invention aims to provide a low-caking rate chemical wastewater reuse treatment system. Through the combination of dynamic permeable arc plates, deformable support plates, and undulating plates, it can effectively maintain the filtration efficiency of the reverse filter plate while effectively achieving dynamic filtration. Maintaining the dynamism of the lower end of the reverse filter plate reduces the adsorption of impurities on the reverse filter plate and filter pores, thereby reducing the probability of clogging and caking of the filter pores. This improves the service life of the reverse filter plate, enhances the continuous efficiency of deep industrial wastewater treatment, reduces water resource consumption, increases wastewater recycling rate, effectively promotes the development of chemical wastewater reuse, and reduces the energy consumption of chemical enterprises.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A low-caking-rate chemical wastewater reuse treatment system includes a depth filter and a wastewater treatment control system. The wastewater treatment control system includes a data processing unit. A reverse filter plate is installed inside the depth filter. The reverse filter plate has multiple filter impurity holes. Multiple limiting rings corresponding to the filter impurity holes are fixedly connected to the lower end of the reverse filter plate. Multiple dynamic permeable arc plates located below the filter impurity holes are fixedly connected to the limiting rings. Each dynamic permeable arc plate has an elastic cavity. A deformation support plate is fixedly connected to the inner wall of the elastic cavity near the limiting rings. A vibration trigger groove is formed on the side of the deformation support plate away from the limiting rings. A pulsating plate is fixedly connected to the vibration trigger groove, and the end of the pulsating plate away from the vibration trigger groove is connected to the elastic support plate. The inner wall of the cavity is fixedly connected, and an electromagnetic repulsion plate is fixedly connected to the inner wall of the vibration trigger groove. A strong magnetic patch that cooperates with the electromagnetic repulsion plate is fixedly connected to the upper end of the wave plate. Through the cooperation of the dynamic water-permeable arc plate, the deformation support plate and the wave plate, the dynamic filtration of the reverse filter plate can be effectively achieved while maintaining the filtration efficiency of the reverse filter plate. The dynamics of the lower end of the reverse filter plate are maintained, reducing the adsorption of impurities on the reverse filter plate and the filter holes, thereby reducing the probability of clogging and caking of the filter holes. While improving the service life of the reverse filter plate, the efficiency of the continuous deep treatment of industrial wastewater is improved, water resource loss is reduced, the wastewater recycling rate is increased, the development of chemical wastewater reuse is effectively promoted, and the production energy consumption of chemical enterprises is reduced.

[0010] Furthermore, a pressure sensing plate is fixedly connected to the inner wall of the vibration trigger groove. The pressure sensing plate is located on the side of the electromagnetic repulsion plate away from the limiting ring and cooperates with the oscillating plate. The cooperation of the pressure sensing plate, the electromagnetic repulsion plate and the strong magnetic patch can effectively maintain the vibration effect of the dynamic permeable arc plate during the sewage filtration process. This allows the dynamic permeable arc plate to continuously deform and recover at the lower end of the filter impurity hole, effectively maintaining a dynamic process, effectively preventing impurities from floating and adsorbing, and improving the sewage filtration effect.

[0011] Furthermore, the input end of the data processing unit is connected to a pressure triggering unit, the input end of the pressure triggering unit is connected to a pressure sensor, and the output end of the data processing unit is connected to a magnetic reset unit, the output end of the magnetic reset unit is connected to an electromagnetic repulsion plate.

[0012] Furthermore, both the vibration trigger groove and the wave plate are made of elastic material, and the force that causes the vibration trigger groove to deform is greater than the force that causes the wave plate to deform.

[0013] Furthermore, a deformation-sensing sheet is fixedly connected between two adjacent dynamic permeable arc sheets. The deformation-sensing sheet includes a flexible mesh and a shape memory metal sheet. A flexible mesh is fixedly connected to one end of each of the two adjacent dynamic permeable arc sheets, and a shape memory metal sheet is fixedly connected between the two flexible meshes.

[0014] Furthermore, the lower end of the reverse filter plate is fixedly connected with a plurality of forced trigger rings corresponding to the filter holes, and the forced trigger rings are located inside the limiting ring. A heat-conducting groove is provided at the lower end of the forced trigger ring, and an electric heating element is fixedly connected in the heat-conducting groove.

[0015] Furthermore, a heat-conducting wire is fixedly connected to the lower end of the heating element, and the lower end of the heat-conducting wire is fixedly connected to the shape memory metal sheet. During the operation of the wastewater reuse treatment system, the deformation state of the deformation temperature sensor is effectively maintained through the action of the heating element and the heat-conducting wire, which facilitates shape control of the deformation temperature sensor and improves its effectiveness.

[0016] Furthermore, the input end of the data processing unit is also connected to a contact triggering unit, and the output end of the data processing unit is also connected to an electric heating control unit, the output end of which is connected to the heating element.

[0017] Furthermore, a contact sensing plate is fixedly connected to the lower end of the forced trigger ring, and the input end of the contact trigger unit is connected to the contact sensing plate. After the dynamic permeable arc plate is squeezed by impurities and undergoes extreme deformation, the contact trigger unit can send a sensing signal, so that the electrothermal control unit controls the temperature of the deformation sensing plate, and the deformation sensing plate assists the dynamic permeable arc plate in performing a forced reset action, effectively maintaining the continuity of the dynamic permeable arc plate's function and improving the service life of the reverse filter plate.

[0018] Furthermore, the electrothermal control unit includes a temperature holding module and a heating module. When the depth filter is started, the temperature holding module is activated, causing the heating element to conduct heat to the deformation sensing element. When the contact trigger unit sends a trigger signal to the data processing unit, the data processing unit controls the heating module in the electrothermal control unit to start, resetting the deformation sensing element. By using the temperature holding module and the heating module, the effect of the deformation sensing element is effectively maintained, while improving the automation level of wastewater reuse treatment, increasing the self-maintenance efficiency of the reverse filter plate, and reducing its maintenance cost.

[0019] Furthermore, the output of the data processing unit is also connected to an early warning unit, which is connected to an alarm. After the data processing unit receives the trigger signal from the contact triggering unit, it simultaneously controls the early warning unit and sends an early warning signal to the staff through the alarm. The staff can judge the usage status of the reverse filter plate based on the frequency of the early warning signal, so as to facilitate timely maintenance and replacement of the reverse filter plate, effectively avoid filtration failures, and reduce the economic losses caused by sewage filtration.

[0044] Example 1:

[0045] Please see Figure 1-11 A low-caking chemical wastewater reuse treatment system includes a depth filter 1 and a wastewater treatment control system. The wastewater treatment control system includes a data processing unit. A reverse filter plate 2 is installed inside the depth filter 1. The reverse filter plate 2 has multiple filter holes 201. Multiple limiting rings 301 corresponding to the filter holes 201 are fixedly connected to the lower end of the reverse filter plate 2. Multiple dynamic permeable arc plates 3 located below the filter holes 201 are fixedly connected to the limiting rings 301. An elastic cavity 302 is formed inside the dynamic permeable arc plate 3. A deformation support plate 6 is fixedly connected to the inner wall of the elastic cavity 302 near the limiting rings 301. A vibration trigger groove 601 is formed on the side of the deformation support plate 6 away from the limiting rings 301. A oscillating plate 7 is fixedly connected to the vibration trigger groove 601, with the oscillating plate 7 away from the vibration trigger groove 601. An electromagnetic repulsion plate 602 is fixedly connected to the inner wall of the elastic cavity 302, and an electromagnetic repulsion plate 602 is fixedly connected to the inner wall of the vibration trigger groove 601. A strong magnetic patch 701 that cooperates with the electromagnetic repulsion plate 602 is fixedly connected to the upper end of the oscillating plate 7. Through the cooperation of the dynamic permeable arc plate 3, the deformation support plate 6 and the oscillating plate 7, the dynamic filtration of the reverse filter plate 2 can be effectively achieved while maintaining the filtration efficiency of the reverse filter plate 2. The dynamics of the lower end of the reverse filter plate 2 are maintained, the adsorption of impurities on the reverse filter plate 2 and the filter holes 201 are reduced, and the probability of clogging and caking of the filter holes 201 is reduced. While improving the service life of the reverse filter plate 2, the efficiency of the continuous deep treatment of industrial wastewater is improved, the loss of water resources is reduced, the wastewater recycling rate is increased, the development of chemical wastewater reuse is effectively promoted, and the production energy consumption of chemical enterprises is reduced.

[0046] Please see Figure 6 and Figure 7 A pressure sensing plate is fixedly connected to the inner wall of the vibration trigger groove 601. The pressure sensing plate is located on the side of the electromagnetic repulsion plate 602 away from the limiting ring 301 and cooperates with the wave plate 7. The cooperation of the pressure sensing plate, the electromagnetic repulsion plate 602 and the strong magnetic patch 701 can effectively maintain the vibration effect of the dynamic permeable arc plate 3 during the sewage filtration process. This allows the dynamic permeable arc plate 3 to continuously deform and recover at the lower end of the filter impurity hole 201, effectively maintaining a dynamic process, effectively preventing impurities from floating and adsorbing, and improving the sewage filtration effect.

[0047] Please see Figure 1 and Figure 2 The input end of the data processing unit is connected to a pressure triggering unit, the input end of which is connected to a pressure sensor. The output end of the data processing unit is connected to a magnetic reset unit, and the output end of the magnetic reset unit is connected to an electromagnetic repulsion plate 602.

[0048] Please see Figure 6 and Figure 7 Both the vibration trigger groove 601 and the wave plate 7 are made of elastic material, and the force of deformation generated by the vibration trigger groove 601 is greater than the force of deformation generated by the wave plate 7.

[0049] Please see Figure 3-5 In 8-11, a deformation-sensing sheet 4 is fixedly connected between two adjacent dynamic permeable arc sheets 3. The deformation-sensing sheet 4 includes a flexible mesh and a memory metal sheet. A flexible mesh is fixedly connected to one end of each of the two adjacent dynamic permeable arc sheets 3, and a memory metal sheet is fixedly connected between the two flexible meshes.

[0050] Please see Figure 3-5 and Figure 8-11 The lower end of the reverse filter plate 2 is fixedly connected with a plurality of forced trigger rings 5 ​​corresponding to the filter holes 201, and the forced trigger rings 5 ​​are located inside the limiting ring 301. A heat conduction groove is provided at the lower end of the forced trigger ring 5, and an electric heating element 501 is fixedly connected in the heat conduction groove.

[0051] Please see Figure 11 A heat-conducting wire is fixedly connected to the lower end of the heating element 501. The lower end of the heat-conducting wire is fixedly connected to the shape memory metal sheet. During the operation of the wastewater reuse treatment system, the deformation state of the deformation temperature sensing element 4 is effectively maintained through the action of the heating element 501 and the heat-conducting wire, which facilitates shape control of the deformation temperature sensing element 4 and improves the effectiveness of the deformation temperature sensing element 4.

[0052] Please see Figure 1 and Figure 2The input end of the data processing unit is also connected to a contact triggering unit, and the output end of the data processing unit is also connected to an electric heating control unit. The output end of the electric heating control unit is connected to the electric heating element 501.

[0053] Please see Figure 8-11 A contact sensing plate is fixedly connected to the lower end of the forced trigger ring 5. The input end of the contact trigger unit is connected to the contact sensing plate. After the dynamic permeable arc plate 3 is squeezed by impurities and undergoes extreme deformation, the contact trigger unit can send a sensing signal, which enables the electrothermal control unit to control the temperature of the deformation sensing plate 4. This allows the deformation sensing plate 4 to assist the dynamic permeable arc plate 3 in performing a forced reset action, effectively maintaining the continuous function of the dynamic permeable arc plate 3 and improving the service life of the reverse filter plate 2.

[0054] Please see Figure 1 and Figure 2 The electric heating control unit includes a temperature holding module and a heating module. The temperature holding module maintains a constant temperature, reducing energy loss. When the depth filter 1 is started, the temperature holding module is activated, causing the heating element 501 to conduct heat to the deformation sensing element 4. When the contact trigger unit sends a trigger signal to the data processing unit, the data processing unit controls the heating module in the electric heating control unit to start, resetting the deformation sensing element 4. By effectively maintaining the function of the deformation sensing element 4 through the temperature holding module and the heating module, the automation level of wastewater reuse treatment is improved, the self-maintenance efficiency of the reverse filter plate 2 is improved, and its maintenance cost is reduced.

[0055] Please see Figure 1 and Figure 2 The output of the data processing unit is also connected to an early warning unit, which is connected to an alarm. After the data processing unit receives the trigger signal from the contact trigger unit, it controls the early warning unit and sends an early warning signal to the staff through the alarm. The staff can judge the usage status of the reverse filter plate 2 based on the frequency of the early warning signal, so as to maintain and replace the reverse filter plate 2 in a timely manner, effectively avoid filtration failure, and reduce the economic losses caused by sewage filtration.

[0056] Please see Figure 1-11 During the startup of the wastewater reuse treatment system, the depth filter 1 is started simultaneously. At the same time, the temperature holding module of the electric heating control unit is also started, so that the electric heating element 501 generates a certain temperature and transfers it to the memory metal sheet of the deformation temperature sensing element 4 through the heat conduction wire. Under the action of the memory metal sheet, the deformation temperature sensing element 4 maintains a downward bending shape. At this time, it has a certain elasticity and can deform with the vibration of the dynamic permeable arc sheet 3 in the cooperation of the flexible mesh.

[0057] When sewage overflows upwards from the bottom under pressure, it overflows through the dynamic permeable arc plate 3 and the filter holes 201 to the upper side of the reverse filter plate 2. At this time, the dynamic permeable arc plate 3 and the filter holes 201 filter impurities in the sewage. Under the action of the flow pressure generated by the overflowing sewage, the dynamic permeable arc plate 3 will bend upwards. At this time, the oscillating plate 7 will deform synchronously. During the continuous deformation process, the oscillating plate 7 will exert squeezing pressure on the pressure sensing plate. The pressure sensing plate transmits a pressure signal to the pressure triggering unit, which processes the signal. The data is then transmitted to the data processing unit. After determining that the pressure meets the required range, the data processing unit controls the magnetic reset unit, activating the power supply to the electromagnetic repulsion plate 602. This causes the electromagnetic repulsion plate 602 to generate magnetic poles with the same magnetism as the strong magnetic patch 701, resulting in like poles repelling each other. This causes the undulating plate 7 to resist the flow pressure under the magnetic force, and also causes the dynamic permeable arc plate 3 to undergo a reset deformation. During the non-reset process of the undulating plate 7, the compressive pressure acting on the pressure sensing plate decreases, and the pressure sensing plate moves towards the pressure contact... The pressure triggering unit transmits a pressure signal, which is then processed by the pressure triggering unit and transmitted to the data processing unit. The data processing unit determines that the pressure does not meet the required range and controls the magnetic reset unit to cut off the power to the electromagnetic repulsion plate 602, thus demagnetizing it. At this point, the undulating plate 7 and the dynamic permeable arc plate 3 continue to bend upwards under the influence of the flow pressure. This cycle effectively maintains the dynamic filtration process of the reverse filter plate 2. Through the cooperation of the dynamic permeable arc plate 3, the deformation support plate 6, and the undulating plate 7, the filtration efficiency of the reverse filter plate 2 is effectively maintained while simultaneously achieving dynamic filtration. This maintains the dynamism of the lower end of the reverse filter plate 2, reducing the adsorption of impurities on the reverse filter plate 2 and the filter holes 201, thereby reducing the probability of clogging and caking of the filter holes 201. This improves the service life of the reverse filter plate 2, enhances the continuous efficiency of deep industrial wastewater treatment, reduces water resource consumption, increases wastewater recycling rate, effectively promotes the development of chemical wastewater reuse, and reduces the energy consumption of chemical enterprises.

[0058] During the continuous flow of sewage, the heat generated by the heating element 501 is absorbed and exchanged, continuously reducing the temperature of the memory metal sheet inside the deformation-sensing element 4, causing it to undergo low-temperature deformation. Under the deformation of the memory metal sheet, the deformation-sensing element 4 bends upward, making it directly contact the heating element 501. With the cooperation of the flexible mesh, this does not affect the mobility of the dynamic permeable arc plate 3. During the continuous filtration process, the impurity content at the lower end of the reverse filter plate 2 gradually increases, causing the mobility of the dynamic permeable arc plate 3 to gradually decrease. Under the continuous action of the flow pressure, the deformation support plate 6 deforms. At this time, the dynamic permeable arc plate 3 bends upward and makes contact with the forced trigger ring 5, causing the contact sensing element to receive a signal and transmit the contact signal to the data processing unit. The data processing unit simultaneously controls the electric heating control unit and the early warning unit. The heating module in the unit is activated, causing the heating element 501 to continuously heat up, which in turn heats the shape memory metal sheet, causing it to undergo high-temperature reset deformation. This resets the deformation-sensing element 4. Through the temperature holding module and the heating module, the function of the deformation-sensing element 4 is effectively maintained, while improving the automation level of wastewater reuse treatment, increasing the self-maintenance efficiency of the reverse filter plate 2, and reducing its maintenance costs. After the dynamic permeable arc plate 3 and the deformation-sensing element 4 reset, the above dynamic filtration process continues, and so on. The early warning unit controls the process, sending an alarm signal to the staff. The staff can judge the usage status of the reverse filter plate 2 based on the frequency of the alarm signal, so as to facilitate timely maintenance and replacement of the reverse filter plate 2, effectively avoiding filtration failures and reducing economic losses caused by wastewater filtration.

[0059] It is worth noting that this invention can be used independently in a wastewater reuse system or in conjunction with backwashing. The operator can choose the appropriate method based on the actual needs of wastewater treatment. This invention can reduce the number of backwashing cycles, thereby still achieving the effects of reducing water resource consumption, increasing wastewater recycling rate, effectively promoting the development of chemical wastewater reuse, and reducing the production energy consumption of chemical enterprises.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
