Abstract
Description
Technical Field
[0001] This utility model relates to the field of sodium persulfate wastewater treatment technology, and in particular to a sodium persulfate wastewater treatment device. Background Technology
[0002] Sodium persulfate has strong oxidizing properties and is widely used in many fields such as chemical synthesis, papermaking and printing, metal processing and environmental protection. In the current technology, the production of sodium persulfate requires the reaction of ammonium persulfate and sodium hydroxide solution in a closed reaction vessel. During the reaction, not only sodium persulfate crystals are produced, but also a large amount of ammonia gas is produced. The ammonia gas dissolves in the solution after the reaction and produces ammonia-containing wastewater.
[0003] A search revealed that utility model patent CN213823640U discloses a device for recovering and treating ammonia water produced during the production of sodium persulfate. By setting up a first hydraulic telescopic rod, a connecting rod, a second hydraulic telescopic rod, and a guide rod, and by fixing the first hydraulic telescopic rod to the connecting rod and the second hydraulic telescopic rod to the guide rod, the concentration and separation device can be effectively moved up and down. This not only facilitates maintenance and cleaning but also reduces the safety risks to workers and allows for more thorough cleaning.
[0004] Although the above-mentioned device can achieve the recycling treatment of ammonia-containing wastewater and obtain additional by-product sodium sulfate, the generated sodium sulfate will be distributed on the top of the second filter screen in the collection tank. Not only is collection inconvenient, but the collection tank also needs to be opened during collection, which leads to the device being unable to operate continuously, affecting the treatment efficiency and making it inconvenient to use in practice.
[0005] Therefore, it is necessary to invent a sodium persulfate wastewater treatment device to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a sodium persulfate wastewater treatment device that can more conveniently collect and output sodium sulfate generated during the recycling process of ammonia-containing wastewater. This reduces the difficulty of collection without affecting the continuous operation of the device, ensuring treatment efficiency while being more convenient in actual use. This solves the problem mentioned in the background art that although the existing device can achieve the recycling treatment of ammonia-containing wastewater and obtain the additional byproduct sodium sulfate, the generated sodium sulfate is distributed on the top of the second filter screen in the collection tank. This is not only inconvenient to collect, but also requires opening the collection tank during collection, which leads to the inability of the device to operate continuously, affecting treatment efficiency and making it inconvenient in actual use.
[0007] According to one aspect of this disclosure, the following technical solution is provided: a sodium persulfate wastewater treatment device, comprising:
[0008] Installation components are used for installing ammonia-containing wastewater treatment facilities;
[0009] An ammonia-containing wastewater treatment facility, wherein the ammonia-containing wastewater treatment facility is used to treat ammonia-containing wastewater; and
[0010] A Glauber's salt collection assembly includes a diverter pipe fixedly connected to the output end of a second fixed frame. A stop valve A is fixedly connected to the first output end of the diverter pipe, and a circulation pipe is fixedly connected to the second output end of the diverter pipe. A receiving pipe is fixedly connected to the output end of the stop valve A. A glass observation window is fixedly nested on the receiving pipe. A stop valve B is fixedly connected to the output end of the receiving pipe, and a drain pipe is fixedly inserted through the bottom side of the receiving pipe. A stop valve C is fixedly connected to the output end of the drain pipe. Filter screens are provided on the inner side of both the second output end of the diverter pipe and the inner side of the drain pipe.
[0011] According to at least one embodiment of the sodium persulfate wastewater treatment apparatus of this disclosure, the mounting assembly includes a base, and a mounting bracket is fixedly disposed on the top of the base.
[0012] According to at least one embodiment of the sodium persulfate wastewater treatment device of this disclosure, two parallel first fixing frames are fixedly arranged on the top inner side of the mounting frame, two parallel second fixing frames are fixedly arranged on the right inner side of the mounting frame, and a support seat is fixedly arranged on the right side of the top of the base.
[0013] According to at least one embodiment of the sodium persulfate wastewater treatment device disclosed herein, the ammonia-containing wastewater treatment mechanism includes a vacuum concentrator fixedly disposed on the top left side of the base, and an ammonia-containing wastewater inlet pipe and an absorbent inlet pipe are fixedly disposed through the top left side of the vacuum concentrator from top to bottom.
[0014] According to at least one embodiment of the sodium persulfate wastewater treatment apparatus of this disclosure, an exhaust pipe is fixedly connected to the gas output end of the top of the vacuum concentrator, a condenser fixedly installed inside two first fixed frames is fixedly connected to the end of the exhaust pipe, a connecting pipe is fixedly connected to the output end of the condenser, and a cooler fixedly installed inside two second fixed frames is fixedly connected to the output end of the connecting pipe.
[0015] According to at least one embodiment of the sodium persulfate wastewater treatment device of this disclosure, the ammonia-containing wastewater treatment mechanism further includes a circulation pipe fixedly connected to the right input end of the vacuum thickener separator, a circulation pump fixedly installed on the top of the support base on the circulation pipe, and a one-way valve on the circulation pipe.
[0016] The technical effects and advantages of this utility model are as follows:
[0017] This invention incorporates a sodium sulfate collection component. When the second fixed frame outputs cooled ammonia-containing wastewater, the ammonia-containing wastewater and the generated sodium sulfate simultaneously enter the diversion pipe. The ammonia-containing wastewater passes through a filter screen and, under the suction of a circulating pump, is returned to the vacuum concentrator for further treatment. The sodium sulfate is blocked by the filter screen and passes through shut-off valve A into the receiving pipe. When sodium sulfate needs to be output during wastewater treatment, shut-off valve A is closed and shut-off valve C is opened. At this time, a sealed chamber is formed inside the receiving pipe, and the residual wastewater inside the receiving pipe is output. Then, shut-off valve B is opened, and the sodium sulfate is actively output under gravity. Compared with the prior art, this invention can more conveniently output and collect sodium sulfate generated during the circulation treatment of ammonia-containing wastewater, reducing the collection difficulty without affecting the continuous operation of the device, ensuring treatment efficiency, and making it more convenient in actual use.

[0028] Figure 2 This is a schematic diagram of the installation assembly 1 and the ammonia-containing wastewater treatment mechanism 2 of a sodium persulfate wastewater treatment device according to one embodiment of the present disclosure.
[0029] Figure 3 This is a schematic diagram of the structure of the Glauber's salt collection component 3 of a sodium persulfate wastewater treatment device according to one embodiment of the present disclosure.
[0030] like Figures 1-3 As shown, the sodium persulfate wastewater treatment device disclosed herein may include components such as: installation assembly 1, ammonia-containing wastewater treatment mechanism 2, and sodium sulfate collection assembly 3.
[0031] like Figure 2 As shown in this disclosure, the mounting assembly 1 includes a base 11, a mounting bracket 12 is fixedly mounted on the top of the base 11, two parallel first mounting brackets 13 are fixedly mounted on the top inner side of the mounting bracket 12, two parallel second mounting brackets 14 are fixedly mounted on the right inner side of the mounting bracket 12, and a support base 15 is fixedly mounted on the right side of the top of the base 11.
[0032] It should be noted that the base 11 is made of high-strength carbon steel and has anti-slip pads on the bottom. It is fixed to the horizontal ground with expansion bolts to ensure the stability of the device during operation.
[0033] The mounting bracket 12 is a frame structure, welded to the top of the base 11. Two first fixing brackets 13 on the inner top are distributed in parallel, and the spacing is precisely adjusted according to the size of the condenser 25. The condenser 25 is fixed between the first fixing brackets 13 by bolts. Two second fixing brackets 14 on the right side of the inner side of the mounting bracket 12 are perpendicular to the first fixing brackets 13 and are used to fix the cooler 27.
[0034] The support base 15 is located on the right side of the base 11, and a shock-absorbing pad is installed on the top surface. The circulation pump 29 is fixed to the support base 15 by bolts.
[0035] like Figure 2 As shown, in a preferred embodiment, the ammonia-containing wastewater treatment mechanism 2 includes a vacuum concentrator 21 fixedly installed on the top left side of the base 11. An ammonia-containing wastewater inlet pipe 22 and an absorbent inlet pipe 23 are fixedly installed through the top left side of the vacuum concentrator 21 from top to bottom. An exhaust pipe 24 is fixedly connected to the gas output end of the vacuum concentrator 21. A condenser 25, fixedly installed inside two first fixed frames 13, is fixedly connected to the end of the exhaust pipe 24. A connecting pipe 26 is fixedly connected to the output end of the condenser 25. A cooler 27, fixedly installed inside two second fixed frames 14, is fixedly connected to the output end of the connecting pipe 26. The ammonia-containing wastewater treatment mechanism 2 also includes a circulation pipe 28 fixedly connected to the right input end of the vacuum concentrator 21. A circulation pump 29, fixedly installed on the top of the support base 15, is installed on the circulation pipe 28. A one-way valve is installed on the circulation pipe 28.
[0036] Therefore, ammonia-containing wastewater generated during the sodium persulfate production process is input into the vacuum concentrator 21 through the ammonia-containing wastewater input pipe 22, while absorbent is input through the absorbent input pipe 23. The ammonia-containing wastewater and absorbent are mixed and concentrated inside the vacuum concentrator 21, where sodium sulfate crystals are generated. The vaporized ammonia-containing wastewater is then input into the condenser 25 through the exhaust pipe 24 for condensation, and then input into the cooler 27 through the connecting pipe 26 for cooling and crystallization. At this time, sodium sulfate is produced in the ammonia-containing wastewater. Subsequently, the ammonia-containing wastewater carries the sodium sulfate into the sodium sulfate collection component 3 for treatment. The sodium sulfate is retained inside the sodium sulfate collection component 3, while the ammonia-containing wastewater is returned to the vacuum concentrator 21 through the circulation pipe 28 for further treatment.
[0037] The staged treatment of condenser 25 and cooler 27 ensures that the vaporized ammonia-containing wastewater is fully condensed and sodium sulfate is efficiently crystallized. The flow rate of circulating pump 29 is controlled at 5-10 m³ / h, so that the flow velocity of wastewater in circulating pipe 28 is maintained at 1.5-2 m / s, which ensures that sodium sulfate is effectively intercepted by filter screen 37, and avoids crystal breakage due to excessive flow velocity.
[0038] like Figure 3As shown in this disclosure, the Glauber's salt collection assembly 3 includes a diversion pipe 31 fixedly connected to the output end of the second fixed frame 14. A stop valve A32 is fixedly connected to the first output end of the diversion pipe 31. The second output end of the diversion pipe 31 is fixedly connected to the circulation pipe 28. A receiving pipe 33 is fixedly connected to the output end of the stop valve A32. A glass observation window is fixedly nested on the receiving pipe 33. A stop valve B34 is fixedly connected to the output end of the receiving pipe 33. A drain pipe 35 is fixedly provided through the bottom side of the receiving pipe 33. A stop valve C36 is fixedly connected to the output end of the drain pipe 35. Filter screens 37 are provided on the inner side of the second output end of the diversion pipe 31 and the inner side of the drain pipe 35.
[0039] Therefore, when the second fixed frame 14 outputs the cooled ammonia-containing wastewater, the ammonia-containing wastewater and the generated sodium sulfate simultaneously enter the diversion pipe 31. The ammonia-containing wastewater passes through the filter screen 37 and is pumped back to the vacuum concentrator 21 through the circulation pipe 28 by the circulation pump 29 for further treatment. The sodium sulfate is blocked by the filter screen 37 and passes through the shut-off valve A32 into the receiving pipe 33. When it is necessary to output sodium sulfate during the wastewater treatment process, the shut-off valve A32 is closed and the shut-off valve C36 is opened. At this time, a sealed chamber is formed inside the receiving pipe 33, and the residual wastewater inside the receiving pipe 33 is output. Then, the shut-off valve B34 is opened, and the sodium sulfate is actively output under the action of gravity. Compared with the existing technology, it is more convenient to output and collect sodium sulfate generated during the circulation treatment of ammonia-containing wastewater, reducing the difficulty of collection without affecting the continuous operation of the device, ensuring treatment efficiency, and making it more convenient in actual use.
