Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, and particularly relates to a device for improving the water quality of water used in dyeing production. Background Art

[0002] Dyeing production refers to the process of applying dyes or pigments to the surface of raw materials (such as fibers, leather, paper, etc.) in industries such as textiles, leather, and paper to obtain the desired color and effect. Dyeing production usually has high requirements for water quality. Impurities, heavy metal ions, microorganisms, etc. in water will affect the dyeing effect and product quality. Therefore, it is necessary to strictly control and treat the water quality, which involves the use of some devices to improve the water quality of water used in dyeing production. However, there are still some problems with existing water quality improvement devices. For example, the patent with the publication number CN207391153U discloses a water softening treatment device for dyeing and finishing. Specifically, hard water in rivers, lakes, and reservoirs is collected in a water storage tank, filtered twice, and then adsorbed through a resin reaction tank to obtain pure softened water. Although this device can effectively solve the technical problem of overly hard water quality for dyeing and finishing water, during the regeneration process of the resin for softening treatment, the distribution of the regeneration agent is not uniform and is easily retained on the resin. Long-term adsorption will cause the regeneration efficiency of the resin to decline and become inconsistent, thereby affecting the uniformity of the softening effect, resulting in an increase in water hardness, easy formation of water scale, and affecting the dyeing and finishing process. Content of the Utility Model

[0003] (1) Technical Problems to be Solved

[0004] In view of the limitations of existing softening devices, the purpose of the present utility model is to provide a device for improving the water quality of dyeing water. By segmentally softening raw water and the step-by-step regeneration technology, the resin is processed in segments to achieve precise control of each resin tank, reduce the concentrated accumulation and residue of the regeneration agent, improve the quality of softened water, and at the same time, ion exchange and regeneration can be carried out more evenly, improve the uniformity of the softening and regeneration effects, and further improve the water quality of dyeing and finishing.

[0005] (2) Technical Solutions

[0006] To achieve the above object, the present utility model provides the following technical solution: A device for improving the water quality of dyeing production water, comprising a resin reaction tank, a softening module fixedly connected to the resin reaction tank, and a regeneration module fixedly connected to the resin reaction tank. Inside the resin reaction tank, there are several partitions. The several partitions evenly divide the resin reaction tank into a first resin section, a second resin section, and a third resin section. The several partitions and the inner wall of the resin reaction tank are both provided with wavy patterns. The softening module includes a water storage tank. The water storage tank is fixedly connected to the first resin section, the second resin section, and the third resin section respectively through a first multi-way control valve. The regeneration module includes a second multi-way control valve. The second multi-way control valve includes three regeneration liquid shunt pipes and three regeneration liquid delivery pipes. The other ends of the three regeneration liquid shunt pipes are respectively connected to a high-concentration tank, a medium-concentration tank, and a low-concentration tank. The other ends of the three regeneration liquid delivery pipes are threadedly connected to the first resin section, the second resin section, and the third resin section respectively. Regeneration liquid output pipes are fixedly connected to the first resin section, the second resin section, and the third resin section. The other ends of the three regeneration liquid output pipes are simultaneously connected to a second water pump. The bottom end of the second water pump is fixedly connected to a second liquid collecting pipe. The other end of the second liquid collecting pipe is fixedly connected to a recovery tank. The left bottom end of the recovery tank is fixedly connected to a return pipe. The other end of the return pipe is fixedly connected to a regeneration liquid supply tank. This device aims to improve the water quality used in the dyeing production process. Through softening and regeneration treatment, the hardness and impurities in the water are reduced, and the purity of the water is increased, thereby improving the dyeing effect and extending the service life of the equipment. The resin reaction tank is evenly filled with ion exchange resin that can soften raw water, and the reaction tank is evenly divided into three reaction sections, namely the first resin section, the second resin section, and the third resin section, by partitions, so that independent reactions and controls can be carried out between each reaction section without affecting each other. At the same time, wavy patterns are provided on the surface of the partitions and around the inner wall of the resin reaction tank to help increase the contact area between the resin and water, and at the same time guide the water flow to enhance the exchange effect.

[0007] Specifically, first, through the softening module, after the raw water enters the water storage tank, under the control of the first multi-way control valve, the raw water is evenly distributed to the three resin sections of the resin reaction tank. The ion exchange resin in the three resin sections simultaneously softens this raw water to reduce the hardness of the water. The water softened in the three resin sections will then be output outside the three resin sections through three raw water output pipes and finally merged into the softening tank. The water stored in the softening tank is all the water that has been softened by the ion exchange resin.

[0008] The process of softening raw water by ion exchange resin mainly involves exchanging hardness ions (such as calcium and magnesium ions) in water with sodium ions, thereby reducing water hardness. As the water treatment volume increases, the sodium ions on the resin are gradually exchanged completely, and the exchange sites on the resin are occupied by calcium and magnesium ions. When the resin is saturated, it will lose its softening ability. Therefore, it is necessary to displace the calcium and magnesium ions in the resin through the regeneration process to restore the ion exchange ability of the resin. Therefore, the three resin sections of the resin reaction tank are additionally connected with a regeneration module. The regeneration process is that the regeneration liquid in the high-concentration tank, medium-concentration tank, and low-concentration tank enters the first resin section, second resin section, and third resin section respectively through three regeneration liquid delivery pipes under the action of the second branch control valve in sequence. The regeneration liquid entering the three resin sections contacts the ion exchange resin in the resin section to carry out ion exchange reaction. That is to say, the second control valve first controls the regeneration liquid in the high-concentration tank to be evenly distributed into the first resin section, second resin section, and third resin section through three regeneration liquid delivery pipes, reacts with the ion exchange resin, and then is respectively transported to the recovery tank through three regeneration liquid output pipes. This is the high-concentration regeneration treatment carried out first. Subsequently, the second multi-way control valve controls the regeneration liquid in the medium-concentration tank to be evenly distributed into the three resin sections through three regeneration liquid delivery pipes and reacts with the ion exchange resin in the resin section to further reduce the sodium ions of the resin. The treated liquid then enters the recovery tank through three regeneration liquid output pipes. This is the second medium-concentration regeneration treatment for the ion exchange resin. Then, through the second multi-way control valve, the regeneration liquid in the low-concentration tank is controlled to be evenly distributed into the three resin sections through three regeneration liquid delivery pipes and reacts with the ion exchange resin in the resin section to carry out the final displacement and flushing of the resin. Through step-by-step regeneration, the ion exchange resin is fully displaced, enabling the ion exchange resin to quickly restore its softening ability.

[0009] Preferably, the first multi-way control valve includes a first delivery pipe and three raw water input pipes. The other end of the first delivery pipe is fixedly connected with a water storage tank. The other ends of the three raw water input pipes are respectively fixedly connected with the first resin section, the second resin section, and the third resin section. The process of softening raw water is mainly controlled by the first multi-way control valve. The water storage tank is connected to the first multi-way control valve through the first delivery pipe, enabling the raw water in the water storage tank to enter the first multi-way control valve through the first delivery pipe. Subsequently, under the action of the first multi-way control valve, it is evenly distributed into the first resin section, the second resin section, and the third resin section, and the three resin sections can independently treat the raw water.

[0010] Preferably, raw water output pipes are fixedly connected to the first resin section, the second resin section, and the third resin section respectively. The other ends of the three raw water output pipes are simultaneously connected to a first water pump. The bottom end of the water pump is fixedly connected to a first water collecting pipe, and the other end of the first water collecting pipe is fixedly connected to a soft water tank. After the raw water enters the first resin section, the second resin section, and the third resin section, contacts with the ion exchange resin and is softened, it will be output through the corresponding raw water output pipes respectively under the action of the water pump, concentrated in the first water collecting pipe, and then enter the softening tank.

[0011] Preferably, first check valves are fixedly connected to the joints of the three raw water output pipes and the first resin section, the second resin section, and the third resin section respectively. Here, the first check valve is a one-way valve installed at the joint of the raw water output pipe and the resin section, which is used to prevent liquid backflow and at the same time prevent the regeneration liquid from entering the raw water output pipeline. Each raw water output pipe is equipped with a first check valve before being connected to the resin section. That is, the first check valve 1 is installed at the joint of the raw water output pipe 1 and the first resin section, the first check valve 2 is installed at the joint of the raw water output pipe 2 and the second resin section, and the first check valve 3 is installed at the joint of the raw water output pipe 3 and the third resin section.

[0012] Preferably, second check valves are fixedly connected to the joints of the three regeneration liquid output pipes and the first resin section, the second resin section, and the third resin section respectively. Similarly, the second check valve here is a one-way valve installed at the joint of the regeneration liquid output pipe and the resin section, which is used to prevent liquid backflow and at the same time prevent the raw water from entering the regeneration liquid pipeline. Each regeneration liquid output pipe is equipped with a second check valve before being connected to the resin section. That is, the second check valve 1 is installed at the joint of the regeneration liquid output pipe 1 and the first resin section, the second check valve 2 is installed at the joint of the regeneration liquid output pipe 2 and the second resin section, and the second check valve 3 is installed at the joint of the regeneration liquid output pipe 3 and the third resin section. When softening treatment is carried out, the presence of the second check valve prevents the raw water from entering the regeneration liquid pipeline. Similarly, when regeneration treatment is carried out, the presence of the first check valve prevents the regeneration liquid from entering the raw water pipeline, ensuring that the softening treatment and the regeneration treatment can be carried out independently without affecting each other.

[0013] Preferably, a number of filter nets are evenly arranged in the water storage tank. The mesh diameters of the filter nets gradually decrease from top to bottom. When raw water enters the water storage tank, it will first pass through the filter nets for sedimentation and filtration. There are three layers of filter nets in total, and their mesh diameters gradually decrease from top to bottom. That is to say, the filter nets in the water storage tank include a large-aperture filter net installed in the upper part of the water storage tank, which has a relatively large aperture and is mainly used to filter large suspended matters and particles, such as leaves and sediment. The medium-aperture filter net installed in the middle layer has a smaller aperture and is responsible for intercepting medium-sized particles and suspended matters, such as finer sediment and particulate impurities. The small-aperture filter net is located at the bottom of the water storage tank and has the smallest aperture. It is mainly used to filter fine suspended matters and tiny particles to ensure the purity of water. After the raw water enters the water storage tank, the impurities and particles in the water will pass through the filter nets with different apertures layer by layer along with the water flow, and finally relatively pure raw water will enter the resin reaction tank.

[0014] Preferably, a recovery device is arranged inside the recovery tank. The left bottom end of the recovery tank is fixedly connected with a return pipe. After the regenerant wastewater that has come into contact with the ion exchange resin for reaction enters the recovery tank, it will be recovered and processed in the recovery tank to effectively recover the useful components in the waste liquid, such as regenerant and chemical agents. These recovered waste liquids will flow out through the return pipe and be collected, waiting for the next reuse.

[0015] Preferably, an activated carbon adsorption device is arranged on the inner wall of the first water collecting pipe. After the softened water flows through the first water collecting pipe, the activated carbon adsorption device will adsorb the softened water to further purify the water quality. The activated carbon adsorption device here is designed to be compact and easy to install and replace. Specifically, it can be an activated carbon coating fixed on the inner wall of the water collecting pipe to form a uniform adsorption coating, a filter net with activated carbon, or an activated carbon filling layer, etc.

[0016] Preferably, the first multi-way control valve and the second multi-way control valve are electrically connected to the terminal control system. Both the first multi-way control valve and the second multi-way control valve can be independently controlled through the terminal. That is to say, the terminal control system will calculate the optimal operation mode based on the preset parameters and real-time data, generate control commands, and then transmit the control commands to the first and second multi-way control valves through signal lines to adjust the opening and closing states of the valves, thereby controlling the first resin section, the second resin section, and the third resin section to react and soften the raw water, reduce the hardness of the water, and improve the water quality of the dyeing water.

[0017] (III) Beneficial effects

[0018] (1) Through multi-concentration step-by-step regeneration treatment, that is, using regeneration liquids with high, medium, and low concentrations to treat the resin step by step, ensuring the maximization of the regeneration effect, enabling the ion exchange resin to quickly restore its softening ability, making the water treatment process continuous and efficient. At the same time, the treated regeneration liquid can be recycled and reused through a recovery device, reducing waste and environmental pollution.

[0019] (2) The resin reaction tank is evenly divided into multiple independent reaction segments by a partition board. Each reaction segment is an independent treatment unit, which can treat the water quality separately, ensuring that the water quality treatment in each stage reaches the best effect. At the same time, it ensures that the treatment process of each reaction segment will not be interfered by other segments, guaranteeing the purity and stability of the final water quality.

[0020] (3) Wave-shaped patterns are provided on both the partition board and the inner wall of the reaction tank, which not only increases the surface area but also plays a role in guiding the water flow and strengthening the fluid mixing, ensuring sufficient contact between the water and the resin, thereby improving the efficiency and effect of the overall system.

Detailed Embodiment

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1: As Figure 1 shown, the first specific embodiment of the present invention provides a device for improving the water quality of dyeing production water, which includes a resin reaction tank 1, a softening module 2 fixedly connected to the resin reaction tank 1, and a regeneration module 3 fixedly connected to the resin reaction tank 1. A plurality of partition plates 11 are arranged inside the resin reaction tank 1. The plurality of partition plates 11 divide the resin reaction tank 1 into a first resin section 101, a second resin section 102, and a third resin section 103 on average. Wave-shaped patterns are provided on the inner walls of the plurality of partition plates 11 and the resin reaction tank 1. The softening module 2 includes a water storage tank 20. The water storage tank 20 is fixedly connected to the first resin section 101, the second resin section 102, and the third resin section 103 respectively through a first multi-way control valve 22. The regeneration module 3 includes a second multi-way control valve 31. The second multi-way control valve 31 includes three regeneration liquid shunt pipes 32 and three regeneration liquid delivery pipes 33. The other ends of the three regeneration liquid shunt pipes 32 are respectively connected to a high-concentration tank 301, a medium-concentration tank 302, and a low-concentration tank 303. The other ends of the three regeneration liquid delivery pipes 33 are threadedly connected to the first resin section 101, the second resin section 102, and the third resin section 103 respectively. Regeneration liquid output pipes 53 are fixedly connected to the first resin section 101, the second resin section 102, and the third resin section 103 respectively. The other ends of the three regeneration liquid output pipes 53 are simultaneously connected to a second water pump 52. The bottom end of the second water pump 52 is fixedly connected to a second liquid collecting pipe 51. The other end of the second liquid collecting pipe 51 is fixedly connected to a recovery tank 5. The left bottom end of the recovery tank 5 is fixedly connected to a return pipe 56. The other end of the return pipe 56 is fixedly connected to a regeneration liquid supply tank 30. By segmenting the softening of raw water and the step-by-step regeneration technology, the resin is processed in segments to achieve precise control of each resin tank segment, reduce the concentrated accumulation and residue of regeneration agents, improve the quality of softened water, and at the same time, ion exchange and regeneration can be carried out more evenly, improve the uniformity of softening and regeneration effects, and further improve the water quality of dyeing and finishing.

[0026] The first multi-way control valve 22 includes a first delivery pipe 21 and three raw water input pipes 23. The other end of the first delivery pipe 21 is fixedly connected to a water storage tank 20. The other ends of the three raw water input pipes 23 are respectively fixedly connected to the first resin section 101, the second resin section 102, and the third resin section 103. The first delivery pipe 21 conveys raw water from the water storage tank 20 to the first multi-way control valve 22, and then the raw water is introduced into each resin section through the three raw water input pipes 23, enabling the raw water to be evenly distributed to each reaction section, avoiding the problem of some sections being overused or other sections being in a low-flow state. Additionally, since the raw water can be evenly distributed to each resin section, the resin in each section can fully participate in the ion exchange and water quality treatment process. Such an even distribution helps to maximize the utilization efficiency of the resin, extend the service life of the resin, reduce replacement and maintenance costs. At the same time, different resin sections may be optimized for different water quality problems, which can ensure that each resin section performs ion exchange and water quality adjustment according to the design requirements, thereby improving the overall water quality treatment effect and consistency.

[0027] Raw water output pipes 43 are fixedly connected to the first resin section 101, the second resin section 102, and the third resin section 103 respectively. The other ends of the three raw water output pipes 43 are simultaneously connected to a first water pump 42. The bottom end of the water pump 42 is fixedly connected to a first water collecting pipe 41. The other end of the first water collecting pipe 41 is fixedly connected to a soft water tank 4. Each resin section is connected with a raw water output pipe 43, and these pipes respectively lead out the water treated by the resin. Through the action of the first water pump 42, these treated waters are effectively pumped into the first water collecting pipe 41 and the soft water tank 4. This ensures that the treated water quality remains at a high quality level to meet the production and use requirements. Moreover, since each resin section has an independent raw water output pipe 43 connected to the water pump 42, cross-contamination or mixing of water quality between different resin sections can be effectively avoided, ensuring the stability and consistency of water quality treatment. The use of the water pump 42 ensures that under different working conditions, such as flow rate changes or pressure fluctuations, the system can still maintain a stable water quality output, thereby improving the water quality stability in the dyeing production process.

[0028] Three raw water output pipes 43 are fixedly connected with first check valves 45 at the connection points with the first resin section 101, the second resin section 102, and the third resin section 103. The main function of the first check valve 45 is to prevent reverse flow of water in the system, ensuring that the water flows only in the predetermined direction. This can effectively avoid the mixing or contamination between untreated and treated water. At the same time, by preventing reverse flow, the first check valve 45 helps protect the resin and other treatment equipment from untreated or contaminated water. This helps extend the service life of the resin, reduce the frequency of maintenance and replacement, and improve the overall reliability and stability of the system. The presence of the first check valve 45 ensures that the system can maintain a stable water quality output under different operating conditions, enhancing the safety and operability of the system.

[0029] Three regenerant output pipes 53 are fixedly connected with second check valves 55 at the connection points with the first resin section 101, the second resin section 102, and the third resin section 103. Similarly, the main function of the second check valve 55 is to prevent reverse flow of the regenerant in the system, thus avoiding cross-contamination of the regenerant between different resin sections. And by using the second check valve 55, it is ensured that the regenerant flows only in the predetermined direction, which can effectively prevent the mixing of the regenerant and the raw water and maintain the quality and consistency of the regenerant.

[0030] A number of filter meshes 200 are evenly arranged in the water storage tank 20. The mesh diameters of the number of filter meshes 200 gradually decrease from top to bottom. The fact that the diameters of the filter meshes 200 gradually decrease from top to bottom means that the water flow will be gradually filtered more meticulously when passing through the filter meshes. The larger-diameter filter meshes can quickly remove larger particulate matter, while the smaller-diameter filter meshes can more effectively capture smaller particles and suspended substances. Such a cascaded filtration design can effectively improve the overall filtration effect and ensure the cleanliness and safety of the water quality in the water storage tank. At the same time, by using filter meshes with different particle sizes, impurities and pollutants in the water can be removed more thoroughly. Especially in the treatment of water used in dyeing production, the gradually optimized filtration process helps reduce the accumulation of particulate matter and the residue of pollutants, thereby enhancing the stability and reliability of the water quality. In addition, the more meticulous filtering ability can effectively reduce the abrasion and blockage of the equipment and pipelines by particulate matter in the water. This helps extend the service life of the water storage tank and its connecting components, reduce the frequency of maintenance and cleaning, and lower the operating costs.

[0031] Inside the recycling bin 5, a recycling device 50 is provided. At the left bottom end of the recycling bin 5, a reflux pipe 56 is fixedly connected. The recycling device 50 inside the recycling bin can effectively collect and process the regenerated liquid output from the first resin section 101, the second resin section 102, and the third resin section 103. These regenerated liquids contain adsorbed pollutants and impurities. After being processed by the recycling device 50, the useful components can be recycled. By recycling the regenerated liquid, the environmental load can be reduced. The recycling and utilization of pollutants and chemical substances in the regenerated liquid help reduce waste emissions and resource waste, which conforms to the principle of sustainable development. In addition, by recycling the regenerated liquid, the use of new treatment agents and the cost of waste treatment can be reduced, while the waste of water resources can be reduced, thereby reducing the overall cost in the long-term operation.

[0032] An activated carbon adsorption device 46 is provided on the inner wall of the first water collecting pipe 41. The activated carbon adsorption device 46 can effectively remove organic matters, residual chlorine, peculiar smells, pigments, etc. in the water, thereby improving the water quality. Especially in the water used for dyeing production, the activated carbon adsorption device can effectively remove dye residues and other organic matters, ensuring that the treated water quality meets the production requirements.

[0033] The first multi-way control valve 22 and the second multi-way control valve 31 are electrically connected to the terminal control system. By establishing an electrical connection with the terminal control system, the automatic control of the entire dyeing production water treatment device can be realized. The terminal control system can accurately control operations such as the opening and closing of valves and the adjustment of flow rates according to the preset parameters and the data fed back by sensors to ensure the stability and efficiency of the water quality treatment process. At the same time, after establishing the electrical connection, the operator can view the operating status of the device, water quality parameters, and equipment operating conditions in real time through the remote monitoring system.

[0034] Working principle: When the device is in use, first, the untreated raw water enters the water storage tank 20 of the device. The raw water entering the water storage tank 20 is filtered and precipitated step by step through the filter screen 200 to obtain relatively clean raw water. Subsequently, the terminal system controls the operation of the first multi-way control valve 22 to evenly distribute the raw water through the three raw water input pipes 23 into the first resin section 101, the second resin section 102, and the third resin section 103 in the resin reaction tank 1. The raw water contacts the ion exchange resin to soften the water. At this time, due to the function of the second check valve 55, the water entering the resin reaction tank 1 will not enter the regenerated liquid output pipe 53. Then, the first water pump 42 is turned on. Under the action of the first water pump 42, the softened water in the first resin section 101, the second resin section 102, and the third resin section 103 will respectively enter the first water collecting pipe 41 through the corresponding three raw water output pipes 43, and then be adsorbed by the activated carbon adsorption device 46 and finally enter the soft water tank 4.

[0035] After the raw water softening treatment, the resin needs to be regenerated. During the regeneration process, the pre-prepared regenerant is transported through three regenerant shunt pipes 32 to the high-concentration tank 301, the medium-concentration tank 302, and the low-concentration tank 303 respectively by the second multi-way control valve 31. Subsequently, the regenerants with different concentrations in the high-concentration tank 301, the medium-concentration tank 302, and the low-concentration tank 303 will be transported into the first resin section 101, the second resin section 102, and the third resin section 103 respectively through the corresponding three regenerant transport pipes 33, and will respectively carry out reduction reactions with the ion exchange resins in each resin section. Subsequently, the second water pump 52 is turned on, and the waste liquids in the three reaction sections will enter the second liquid collecting pipe 51 through the corresponding three regenerant output pipes 53, and enter the recovery tank 5 through the second liquid collecting pipe 51. The recovery device 50 inside the recovery tank 5 processes the waste liquid for recovery, generates a regenerant that can be reused, and flows back into the container for holding the regenerant through the return pipe 56.
