Description

Technical Field

[0001] This invention relates to the field of copper phthalocyanine wastewater treatment technology, specifically to a multi-stage treatment device for copper phthalocyanine wastewater. Background Technology

[0002] The multi-stage treatment device for copper phthalocyanine wastewater is used to purify wastewater before it is discharged after copper phthalocyanine has been used as a dye. It uses a multi-stage treatment process to remove impurities and harmful chemical substances from the wastewater, thereby achieving the standard for wastewater discharge after purification. During the use of copper phthalocyanine solution, fibers and impurities from the fabric to be dyed will be mixed into it, causing pollution to the solution. Therefore, multiple physical and chemical treatments are required for the copper phthalocyanine wastewater solution.

[0003] Existing copper phthalocyanine wastewater treatment generally employs a stripping process. The copper phthalocyanine wastewater is sprayed from top to bottom, while the gas used for stripping is blown upwards. This stripping process creates a secondary gaseous phase and a secondary liquid phase. By separating and treating these gaseous and liquid phases, the copper phthalocyanine wastewater is purified, producing wastewater that meets discharge standards and avoids environmental pollution. However, this process is prone to problems. Residual solid impurities in the wastewater can cause omissions in the stripping process, requiring repeated treatments. This is time-consuming and inefficient. Furthermore, the presence of suspended impurities in the wastewater can damage the treatment equipment during continuous treatment. Additionally, repeated treatments often result in poor removal of suspended impurities, leading to low-quality wastewater awaiting discharge.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing multi-stage treatment device for copper phthalocyanine wastewater. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-stage treatment device for copper phthalocyanine wastewater, which solves the problems mentioned in the background art. Existing multi-stage treatment devices for copper phthalocyanine wastewater are prone to repeated treatment due to the solid residue of impurities in the wastewater, which is time-consuming, inefficient, and easily damages the wastewater treatment equipment. In addition, the effect of cleaning suspended impurities in the wastewater is poor after multiple treatments.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-stage treatment device for copper phthalocyanine wastewater, comprising a filter tank for sequentially treating wastewater and filtering impurities, a multi-effect treatment tank for stripping and flocculation, and a sedimentation tank for settling.

[0007] It also includes: a discharge pipe and a waste discharge pipe, which are installed at the bottom middle position of the multi-effect treatment tank. Inside the multi-effect treatment tank, a conductive pump assembly is fixed by a bracket. The conductive pump assembly and the discharge pipe form a communicating system for liquid discharge.

[0008] The rotating connector is rotatably installed above the middle of the multi-effect treatment tank via a bracket, and the aeration treatment net is connected through the rotating connector. The aeration treatment net achieves blow-off and exhaust and flocculation replacement through air pressure and hydraulic pressure, respectively.

[0009] Preferably, the wastewater is transported between the filtration tank and the multi-effect treatment tank via a pump pipe, and the filtration tank is also equipped with an auger assembly for cleaning floating waste.

[0010] Preferably, the upper end of the discharge pipe is funnel-shaped, wherein the conduction pump assembly is fixedly connected to the upper end of the discharge pipe, and the two are arranged in an "n"-shaped structure inside the multi-effect treatment tank, which acts to discharge the wastewater after the middle layer treatment in the multi-effect treatment tank.

[0011] Preferably, the aeration treatment net includes an outer frame for positioning, with vertical pipe assemblies fixed at equal intervals inside the outer frame. Thin pipes for venting are inclinedly connected through the outer wall of the vertical pipe assemblies. At the same time, a valve is fixed at the lower end of the vertical pipe assembly. Elastic disturbances are connected between adjacent vertical pipe assemblies. The elastic disturbances are used for wastewater turbulence stripping and suspended impurity collection and treatment.

[0012] Preferably, the vertical pipe assembly is connected to the interior of the rotating connector via a connecting hose, wherein the interior of the rotating connector is hollow and used for the transport of gas and liquid.

[0013] Preferably, the thin tubes are evenly distributed at equal intervals, wherein the inner diameter of the thin tubes is smaller than the inner diameter of the vertical tube assembly, and the inclination of the central axis of the thin tubes is toward the liquid transport direction inside the vertical tube assembly.

[0014] Preferably, the elastic disruptor includes two spirally distributed springs, with a damping sheet fixed between adjacent springs. The damping sheet is arranged in a bowl shape. A float is provided on the back of the damping sheet. A circulating pump assembly for circulating and transporting liquid in the multi-effect treatment tank and the vertical pipe assembly is also provided through the rotating connector.

[0015] Preferably, the multi-effect treatment tank is also fixed with a waste discharge channel and a pressure flushing assembly. The pressure flushing assembly is located directly above the waste discharge channel, and a gap is reserved between the two. The gap is designed to provide space for the movement of the rotating connector. The pressure flushing assembly uses hydraulic pressure to flush and discharge the rotating connector and the aeration treatment net on it.

[0016] Preferably, the outer frame of the aeration treatment net is hinged to the middle of the side wall of the rotating connector for rotational connection.

[0017] Meanwhile, the bowl-shaped damping film is divided into four equal sections in the middle, and permanent magnets with magnetic adsorption positioning are embedded in the sections.

[0018] Preferably, the rotating connector has an inverted "T" shaped structure in the middle, and the upper end of the inverted "T" shape of the rotating connector is driven to rotate by a motor gear assembly, and is connected to each other for rotation and penetration by a gas pump assembly.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: This multi-stage treatment device for copper phthalocyanine wastewater utilizes processes such as filtration, stripping, and flocculation sedimentation to achieve highly efficient purification of wastewater. Simultaneously, it achieves high efficiency and comprehensive treatment during purification, minimizing the residue of impurities and harmful substances. Specifically:

[0020] 1. Through the action of the filter tank, multi-effect treatment tank and sedimentation tank, the wastewater is filtered, blown out and aerated, flocculated and scooped and settled in sequence, thereby cleaning and separating impurities and harmful substances in the wastewater and achieving the effect of multi-stage purification treatment.

[0021] Furthermore, the multi-effect treatment tank utilizes a rotating aeration treatment net. During its movement, the aeration operation is carried out through the discharge pipeline formed by the vertical pipe assembly and the thin pipe, which aeration and stripping of the wastewater solution to form secondary substances in the gas and liquid phases, thereby improving the uniformity of wastewater treatment. At the same time, the turbulence device formed by the elastic turbulent device uses physical agitation during wastewater aeration and stripping to make the mixing more uniform and improve the treatment efficiency.

[0022] Furthermore, during flocculation and sedimentation operations with the aeration stripping process shut down, the movement of the aeration treatment net via the rotating connector causes the elastic disruptor to extend and contract under water resistance due to different movement speeds. Therefore, the continuous change in movement speed can improve the mixing efficiency of wastewater and flocculant through the elastic disruptor. At the same time, the contraction of the elastic disruptor caused by the change in movement speed from fast to slow can trap the flocculated impurities suspended in the wastewater within the elastic disruptor, facilitating the separation of suspended impurities from the wastewater during the subsequent movement of the aeration treatment net via the rotating connector.

[0023] 2. In the flocculation and sedimentation treatment process, the liquid circulation channel formed by the start-up of the circulation pump assembly and the rotating connector and the vertical pipe assembly drives the solution to flow and mix. When the vertical pipe assembly forms a high-speed internal solution flow, it will generate negative pressure suction at the narrow tube, making it easier for suspended impurities in the wastewater to gather in the vertical pipe assembly, be adsorbed by negative pressure and positioned by the elastic disturbance device, and facilitate subsequent separation from the wastewater.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1-4The present invention provides a technical solution: a multi-stage treatment device for copper phthalocyanine wastewater, comprising a filter tank 1 for sequentially treating wastewater and filtering impurities, a multi-effect treatment tank 2 for stripping and flocculation, and a sedimentation tank 3 for settling; simultaneously, wastewater is transported between the filter tank 1 and the multi-effect treatment tank 2 via a pump pipe, wherein the filter tank 1 is also equipped with an auger assembly 101 for cleaning floating waste, and the filtration of floating impurities in the filter tank 1 is achieved by cleaning the floating waste using the auger assembly 101.

[0038] Meanwhile, the filter tank 1 can also be used to adjust the pH value of the wastewater. After filtration and pH adjustment to a range of 3.5-5, the wastewater is introduced into the multi-effect treatment tank 2 for stripping, resulting in stripping gas and stripping liquid. The top of the multi-effect treatment tank 2 can be equipped with a large suspended sealed cover for guiding the flow of stripping gas. The stripping gas is then treated with other external equipment such as alkali absorption devices for ammonia removal. The stripping liquid, which is still in the multi-effect treatment tank 2, undergoes flocculation, displacement and other processes to remove flocculation and sedimentation agents and other chemical drugs, thus achieving the treatment of the stripping liquid. The wastewater is then settled and the pH value is readjusted in the sedimentation tank 3 for multi-stage wastewater treatment.

[0039] Secondly, in this technical solution, the discharge pipe 4 and the waste discharge pipe 5 are installed at the bottom middle position of the multi-effect treatment tank 2. The multi-effect treatment tank 2 is equipped with a connecting pump assembly 6 fixed inside by a bracket. The connecting pump assembly 6 and the discharge pipe 4 form a communicating vessel system for drainage. The upper end of the discharge pipe 4 is funnel-shaped. The connecting pump assembly 6 and the upper end of the discharge pipe 4 are fixedly connected. The two are arranged in an "n" shape inside the multi-effect treatment tank 2, which is used to drain the wastewater after the middle layer treatment in the multi-effect treatment tank 2. After the wastewater has undergone aeration, stripping, flocculation, sedimentation and suspended matter removal inside the multi-effect treatment tank 2, the discharge is drained through the discharge pipe 4 by starting the connecting pump assembly 6. The communicating vessel system formed by the two can reduce the usage frequency of the connecting pump assembly 6, improve the drainage efficiency and stability of the discharge pipe 4, and will not affect the discharge of the waste discharge pipe 5. The waste discharge pipe 5 realizes the discharge and cleaning of flocculated sediment impurities through its upper pump structure.

[0040] In this technical solution, the rotating connector 7 has an inverted "T" shaped structure in the middle, and the upper end of the inverted "T" shape of the rotating connector 7 is driven to rotate by a motor gear assembly, and is connected to the gas pump assembly for rotation and through-connection; the rotating connector 7 is rotatably installed above the middle of the multi-effect treatment tank 2 by a bracket, and the aeration treatment net 8 is connected through the rotating connector 7. The aeration treatment net 8 is blown off and vented and flocculated and replaced by air pressure and hydraulic pressure respectively; the vertical pipe assembly 801 is connected to the inside of the rotating connector 7 through a connecting hose, wherein the inside of the rotating connector 7 is hollow, and the hollow inside of the rotating connector 7 is used for the transportation of gas and liquid; by controlling the rotation and internal conduction of the rotating connector 7, the movement of the rotating connector 7 and the aeration treatment net 8 on it can be controlled. When the aeration treatment net 8 moves, since there is a sliding energizing component between the end of the rotating connector 7 and the circular frame inside the multi-effect treatment tank 2, the valve 804 can be provided with starting power and activation signal;

[0041] In the above scheme, when aeration and stripping treatment is required inside the multi-effect treatment tank 2, the rotating connector 7 is driven to rotate around its own vertical central axis by the motor gear assembly. The rotating connector 7, along with the aeration treatment net 8, moves and stirs the wastewater solution in the multi-effect treatment tank 2. At the same time, the gas pump assembly introduces the gas used for aeration and stripping into the rotating connector 7. During this process, the valve 804 is closed, and the gas can only be pressurized and ejected through the thin tube 802, forming a mixed treatment of gas aeration and wastewater stripping. Since the rotating connector 7 and the aeration treatment net 8 are in motion, the efficiency of aeration and stripping and the uniformity of gas distribution can be improved. At the same time, when the rotating connector 7 continues to move and the rotation speed changes repeatedly, the elastic disturbance 803 on the rotating connector 7 changes position. Under the action of the change in the moving speed of the rotating connector 7 and the damping force of the water, the elastic disturbance 803 performs its own repeated extension and retraction movement, achieving a secondary mixing treatment effect of gas aeration and wastewater stripping, and improving the efficiency of aeration and stripping.

[0042] Example 2: Based on Example 1, this example modifies the structure of the elastic disruptor 803, enabling it to be applied not only to the gas aeration and stripping process but also to the flocculation and sedimentation treatment of wastewater solutions. Its operation is as follows:

[0043] The thin tubes 802 are evenly distributed at equal intervals, with the inner diameter of the thin tubes 802 being smaller than the inner diameter of the vertical tube assembly 801. The central axis of the thin tubes 802 is inclined towards the liquid transport direction inside the vertical tube assembly 801. The elastic disruptor 803 includes two spirally distributed springs 8031, with a damping sheet 8032 fixed between adjacent springs 8031. The damping sheet 8032 has a bowl-shaped structure and a float 8034 on its back. A circulation pump assembly 805 for circulating the liquid within the multi-effect treatment tank 2 and the vertical tube assembly 801 is also installed through the rotating connector 7. In this scheme, when the gas pump assembly is turned off, the rotating connector 7 is driven to rotate only by the motor gear assembly. At this time, the rotating connector 7 drives the aeration treatment net 8 to rotate, while the valve 804 is closed and the circulation pump assembly 805 is turned on to release flocculants. During this process, the coagulant, due to the movement of the rotating connector 7 and the aeration treatment net 8, performs flocculation treatment of the wastewater solution. At the same time, due to the water circuit composed of the circulating pump assembly 805, the rotating connector 7, and the vertical pipe assembly 801, a rapidly flowing pressurized water flow is continuously discharged through the valve 804 at the lower end of the vertical pipe assembly 801. The water flow can impact the wastewater solution for flocculation treatment. During this process, due to the continuous high-pressure and high-velocity water flow inside the vertical pipe assembly 801, a negative pressure suction force is formed at the thin pipe 802, which allows the thin pipe 802 to collect the suspended impurities generated by the flocculation treatment in the wastewater solution to the location of the vertical pipe assembly 801. Due to the change in the movement speed of the rotating connector 7, the spring 8031, which causes the expansion and contraction movement, holds the impurities and also adsorbs them to the port of the thin pipe 802, thus separating the suspended flocculated impurities from the wastewater solution.

[0044] Furthermore, the multi-effect treatment tank 2 is also fixed with a waste discharge channel 9 and a pressure flushing assembly 10. The pressure flushing assembly 10 is located directly above the waste discharge channel 9, and a gap is reserved between the two. The gap is designed to provide space for the movement of the rotating connector 7. The pressure flushing assembly 10 uses hydraulic pressure to flush and discharge the rotating connector 7 and the aeration treatment net 8 on it. The outer frame composed of the aeration treatment net 8 is hinged to the middle of the side wall of the rotating connector 7. At the same time, the bowl-shaped damping sheet 8032 is divided into equal sections in the middle section 4, and a permanent magnet 8033 for magnetic adsorption and positioning is embedded in the section.

[0045] After the suspended flocculent impurities are separated from the wastewater solution and limited at the ends of the spring 8031 ​​and the capillary tube 802, the aeration treatment net 8 moves between the waste discharge channel 9 and the pressure flushing assembly 10 as the connecting part 7 and its aeration treatment net 8 move. Under the action of the pressure flushing assembly 10, the flushing liquid is pressurized to apply pressure to the damping sheet 8032, causing the spring 8031 ​​to unfold. The impurities it holds are flushed into the waste discharge channel 9 for discharge. At the same time, the equal distribution of the damping sheet 8032 can withstand the impact pressure of the water liquid. When the flocculent impurities gather at the connection end of the damping sheet 8032 and the spring 8031, the high water pressure will cause the damping sheet 8032 to deform and unfold, preventing the impurities from gathering and facilitating discharge. In order to improve the stability of the spring 8031 ​​in holding the flocculent impurities, fine fibers or other adsorbent materials can be provided on the outside of the spring 8031 ​​to facilitate the separation of the flocculent impurities from the wastewater solution.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
