Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to a high-salt degradation treatment device for printing and dyeing sewage. Background Art
[0002] In the printing and dyeing process, salt substances are usually used for dissolving, fixing and dyeing auxiliaries of dyes. Therefore, a large amount of salt (especially sodium chloride and sodium sulfate) is used in the printing and dyeing process. These salts will dissolve in the production water and be discharged with the wastewater, resulting in a high salt content in the wastewater. Therefore, when discharging, it is necessary to target the high salt content in the printing and dyeing wastewater and reduce the salinity and concentration of organic pollutants through physical, chemical, biological and other methods to meet the discharge standards of printing and dyeing wastewater. During treatment, the wastewater needs to be pretreated, desalinated, degraded, concentrated and recovered in sequence through different devices to meet the standards for discharge or reuse.
[0003] The above is an introduction to the high-salt degradation and treatment equipment of printing and dyeing wastewater:
[0004] 1. Existing treatment equipment is large in size and has complicated treatment steps. Reverse osmosis membranes are usually used in desalination treatment to remove most of the salt and tiny organic particles in the sewage. However, long-term use of reverse osmosis membranes can easily lead to poor filtration effects, requiring staff to shut down for maintenance or replacement, which delays treatment efficiency.
[0005] 2. When traditional treatment devices are evaporating and concentrating sewage, they usually directly add a large amount of sewage into the evaporation and concentration equipment for treatment, which cannot achieve quantitative treatment. As a result, the water in the area has not been completely evaporated, which easily leads to the problem that the sewage cannot be evenly evaporated and concentrated. Utility Model Content
[0006] The purpose of the utility model is to solve the technical problems in the prior art that when the reverse osmosis membrane has poor filtering effect after long-term use, it needs to be shut down for maintenance or replacement, which reduces the processing efficiency of the device and easily causes some water to not be completely evaporated during evaporation and concentration. A high-salt degradation treatment device for printing and dyeing wastewater is proposed.
[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-salt degradation treatment device for printing and dyeing wastewater, comprising a degradation box and a connecting bracket, a desalination barrel bolted to the bottom surface of the degradation box, a concentration barrel fixed to the outlet end of the desalination barrel, an anaerobic tank and an aerobic tank included in the degradation box, a partition box fixed to the inner wall of the degradation box, a reverse osmosis cylinder provided inside the desalination barrel, and two groups of reverse osmosis cylinders, a rotating plate provided inside the desalination barrel, and the two groups of reverse osmosis cylinders are respectively fixed to the interfaces at both ends of the rotating plate, and a heating column is connected to the center of the circle inside the concentration barrel.
[0008] It can be seen that in the above technical solution, the degradation box, desalination barrel and concentration barrel are integrated into one, the device occupies a small area, and the two sets of reverse osmosis cartridges are interchangeable in position. When the filtration effect of one set of reverse osmosis cartridges is poor, they can be automatically replaced without stopping the machine for treatment. The sewage that needs to be evaporated and concentrated is located in the space between the inner wall of the concentration barrel and the heating column. The heating column can rotate to heat and evaporate and concentrate the sewage, thereby improving the quality of concentration.
[0009] Preferably, the connecting ends of the connecting bracket are respectively fixed to the surfaces of the degradation tank, the desalination tank and the concentration tank.
[0010] It can be seen that in the above technical solution, the degradation tank, desalination tank and concentration tank are all reinforced and fixed by connecting brackets, so that the various components are integrated and can be placed in the work area for use.
[0011] Preferably, a transposition motor is connected to the center of the top surface of the rotating plate, and the transposition motor is bolted to the top surface of the desalination barrel.
[0012] It can be seen that in the above technical solution, the transposition motor is used to drive the rotating plate to rotate, so that the positions of the two groups of reverse osmosis cartridges are interchanged.
[0013] Preferably, the bottom of the concentration barrel is connected to a bottom cover, and the heating column is located in a through hole at the center of the bottom surface of the bottom cover, and a control shell is installed on the bottom surface of the bottom cover.
[0014] It can be seen that in the above technical solution, the control shell includes components such as a motor and gears for driving the heating column to rotate to achieve uniform treatment.
[0015] Preferably, the top portion of the bottom cover is sleeved on the surface of the concentration barrel, and the bottom cover is threadedly connected to the surface of the concentration barrel.
[0016] It can be seen that in the above technical solution, the bottom cover can be separated from the concentration barrel at a later stage to recover the salt inside the concentration barrel.
[0017] Preferably, a steam recovery component is provided on the back of the desalination barrel, and an interface of the steam recovery component is connected to the desalination barrel, and the steam recovery component is located at the fixed end of the connecting bracket.
[0018] It can be seen that in the above technical solution, during evaporation and concentration, a pump or other component can be used to draw the steam into the steam recovery component and let it stand for the water to be recovered separately.
[0019] Beneficial effects
[0020] In the utility model, the degradation box, the desalination barrel and the concentration barrel are integrated into one, which reduces the floor space of the device. There is no need to transfer the sewage to different equipment for treatment many times. The treatment steps are simple. When the reverse osmosis cartridge has a poor filtering effect after long-term use, the spare reverse osmosis cartridge can be automatically replaced in an emergency to continue desalination and filtration of the sewage. The structure is simple and there is no need to immediately shut down the device for maintenance, which greatly improves the treatment efficiency of the device.
[0021] In the utility model, the design of the heating column being located at the inner center of the concentration barrel is adopted, so that the sewage that needs to be evaporated and concentrated is located in the space between the inner wall of the concentration barrel and the heating column, avoiding a large amount of sewage being added into the concentration barrel, and the sewage can be evaporated and concentrated quantitatively, so that the wastewater can be evenly distributed in the evaporation and concentration area between the inner wall of the concentration barrel and the heating column, ensuring that the water can be evenly heated in the entire area, avoiding the situation where the local temperature is too high or too low, and improving the evaporation efficiency. The water forms a thin film during the rotation process, which is in full contact with the surface of the heating column and the barrel wall, increasing the heat transfer area, making the water evaporate faster, shortening the concentration time, and the heating column can be rotated during concentration, ensuring uniform heating and concentration of the wastewater, avoiding the problem of uneven concentration, thereby improving the processing capacity and effect of the entire system.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.
[0028] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment:
[0030] Reference Figure 1-4 , a high-salt degradation treatment device for printing and dyeing wastewater, including a degradation box 1 and a connecting bracket 4, a desalination barrel 2 is bolted to the bottom surface of the degradation box 1, and a concentration barrel 3 is fixed to the outlet end of the desalination barrel 2, and the connecting ends of the connecting bracket 4 are respectively fixed to the surfaces of the degradation box 1, the desalination barrel 2 and the concentration barrel 3. The wastewater generated in the textile printing and dyeing process usually contains a variety of pollutants, including dyes, auxiliaries, salts such as sodium sulfate, sodium chloride, etc., organic matter and heavy metals, etc. Therefore, before discharging the printing and dyeing wastewater, it is necessary to target the high salt content in the printing and dyeing wastewater, and reduce the salinity and concentration of organic pollutants through physical, chemical, biological and other methods to make the wastewater meet the discharge or reuse standards. The high-salt degradation treatment device for printing and dyeing wastewater is integrated with the main components of the degradation box 1, the desalination barrel 2 and the concentration barrel 3. After pretreatment, the sewage enters the degradation box 1 for degradation, and then enters the desalination barrel 2 for desalination and other treatments, and finally waits for evaporation and concentration to recover the decomposed salt and water respectively.
[0031] The interior of the degradation box 1 includes an anaerobic tank 11 and an aerobic tank 12. A partition box 13 is fixed to the inner wall of the degradation box 1. For further explanation, the interior of the degradation box includes an anaerobic tank 11 and an aerobic tank 12, which are separated by a partition box 13. The partition box 13 is L-shaped and fixed to the inner wall of the degradation box, wherein the top surface of the partition box 13 is an inclined surface from top to bottom, and the outlet is controlled by a solenoid valve so that the anaerobically treated sewage can flow into the aerobic tank 12 along the inclined surface and the valve. There is no dissolved oxygen in the anaerobic tank 11, and the organic matter in the sewage is decomposed by the metabolism of anaerobic microorganisms to produce methane, carbon dioxide and other gases. The anaerobic decomposition process can effectively reduce the content of organic matter and reduce sludge production. The interior of the anaerobic tank 11 includes but is not limited to anaerobic reactors, stirring devices, gas collection devices and other components. When closure is required, the lid of the anaerobic tank 11 can be closed. The aerobic tank 12 promotes the growth of aerobic microorganisms by providing oxygen to the sewage, thereby decomposing organic pollutants. Aerobic microorganisms feed on organic matter and convert it into carbon dioxide, water and inorganic substances. Oxygen is continuously provided by aeration equipment to ensure that the dissolved oxygen content in the sewage meets the needs of microbial metabolism. The aerobic tank 12 includes but is not limited to aeration equipment, biological filter beds or fillers, stirring devices, etc. The sewage is first degraded by anaerobic microorganisms to reduce the burden of subsequent treatment and produce active gases. Aerobic microorganisms are then used to further degrade residual organic matter, and sufficient dissolved oxygen is provided through aeration to ensure that the water quality purification meets the standards.
[0032] The desalination barrel 2 is provided with a reverse osmosis cylinder 22, and there are two groups of reverse osmosis cylinders 22. Further explanation: there are two groups of reverse osmosis cylinders 22 inside the desalination barrel 2. The reverse osmosis cylinder 22 is a cylindrical RO membrane component. After the sewage is degraded, it can be sent into the RO membrane component by a pump or the like. The RO membrane is made of a multi-layer thin film material with a pore size of about 0.0001 microns, which only allows water molecules to pass through and blocks salt ions and other dissolved substances. The reverse osmosis membrane technology is used for further desalination treatment to remove most of the salt and tiny organic particles in the sewage, so that the salinity is reduced to meet the discharge or reuse standards. A rotating plate 21 is provided in the middle, and two groups of reverse osmosis cylinders 22 are respectively fixed to the interfaces at both ends of the rotating plate 21. A transposition motor 23 is connected to the center position of the top surface of the rotating plate 21, and the transposition motor 23 is bolted to the top surface of the desalination barrel 2. When one of the reverse osmosis cylinders 22 has a poor filtration effect after long-term use, another new reverse osmosis cylinder 22 can be exchanged with it to continue to effectively carry out desalination treatment. The two groups of reverse osmosis cylinders 22 are located at both ends of the rotating plate 21. The transposition motor 23 can be used to rotate the rotating plate 21, so that the positions of the two groups of reverse osmosis cylinders 22 are exchanged at appropriate time periods.
[0033] A heating column 31 is connected to the center of the circle inside the concentration barrel 3. It is necessary to explain that the concentration barrel 3 contains a heating column 31, which is an electric heating component. Electric heating is used to evaporate the sewage inside the concentration barrel 3. Since the heating column 31 is located at the center of the circle inside the concentration barrel 3, the sewage will fall into the space between the heating column 31 and the inner wall of the concentration barrel 3 along the curved surface at the top of the heating column 31 after entering the concentration barrel 3. When excessive sewage is added, it will overflow, so that the concentration barrel 3 can be quantitatively concentrated. The heating column 31 can rotate independently inside the concentration barrel 3, so that the wastewater can be evenly distributed in the evaporation and concentration area between the inner wall of the concentration barrel 3 and the heating column 31. This design ensures that the water can be heated evenly throughout the entire area, avoiding local temperatures that are too high or too low, and improving evaporation efficiency. The water forms a thin film during rotation, fully contacting the surface of the heating column 31 and the barrel wall, increasing the heat transfer area, making the water evaporate faster, and shortening the concentration time. The movement of the rotating heating column 31 can prevent water from staying in a fixed area for a long time, preventing local areas from overheating and causing scaling problems.
[0034] The bottom of the concentration barrel 3 is connected to a bottom cover 32, and the heating column 31 is located in the through hole at the center of the bottom surface of the bottom cover 32. A control shell 33 is installed on the bottom surface of the bottom cover 32. The top part of the bottom cover 32 is sleeved on the surface of the concentration barrel 3, and the bottom cover 32 is threadedly connected to the surface of the concentration barrel 3. The control shell 33 is located on the bottom surface of the bottom cover 32. The control shell 33 contains components such as a motor for driving the heating column 31. After evaporation and concentration are completed, the bottom cover 32 can be rotated to separate the bottom cover 32 from the threaded part on the surface of the concentration barrel 3, so that the bottom cover 32 can be taken out to recover the concentrated salt. Similarly, when installing, it is only necessary to thread the bottom cover 32 to the threaded part on the surface of the concentration barrel 3.
[0035] A steam recovery assembly 5 is provided on the back of the desalination barrel 2, and the interface of the steam recovery assembly 5 is connected to the desalination barrel 2, and the steam recovery assembly 5 is located at the fixed end of the connecting bracket 4. During evaporation and concentration, a pump or other component can be used to draw steam into the steam recovery assembly 5 and let it stand to recover water separately. The concentration barrel 3 and the desalination barrel 2 are connected, and the evaporated and concentrated steam gathers upward in the cavity of the desalination barrel 2, and the pump can recover the steam when extracting it from the desalination barrel 2.
