[0002] In the waste nitric acid recovery and treatment process, waste sulfuric acid and solid ferrous sulfate are successively added into a dissolution tank, and a stirring pump is used to stir them. At the same time, low-pressure steam is introduced to make the temperature reach 70 °C, so that the solid ferrous sulfate is completely dissolved. The mixed solution in the dissolution tank is pumped into the reactor by a pump, and waste nitric acid is added. At the same time, oxygen is introduced, and the reactor valve is closed. After the raw and auxiliary materials undergo oxidation, hydrolysis, and polymerization reactions in a closed environment, a dilute solution of polyferric sulfate is obtained. Therefore, a large amount of wastewater will be discharged from the reactor after preparation, so a wastewater treatment device is needed to treat the wastewater.

Detailed Embodiment

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4 , a treatment device for discharging waste acid from a reaction kettle in this embodiment, including a mounting frame 1. A collection box 11 is fixed on the frame of the mounting frame 1, a second water pump 19 is installed on the left side of the collection box 11 and is communicated with it, and a first water pump 4 and a water storage tank 2 are installed on the right side of the collection box 11. A coarse filtration component communicated with the water guiding end of the first water pump 4 is also installed on the mounting frame 1. The water pumping end of the first water pump 4 is communicated with the bottom of the front of the water storage tank 2. A sewage guiding pipe 3 is fixed above the water pumping end of the first water pump 4 on the front of the water storage tank 2. A double-chamber block 8 is fixed on the front of the collection box 11, and an activated carbon filter cylinder 10 communicated with the top of the collection box 11 is installed on the top. The left chamber of the double-chamber block 8 is communicated with the water guiding end of the second water pump 19, and a circulation pipe 20 and a liquid outlet pipe 7 communicated with the coarse filtration component are respectively fixed at the bottoms of the left chamber and the right chamber of the double-chamber block 8. The circulation pipe 20 is a one-way valve pipe, and a liquid guiding pipe 9 communicated with the water inlet end of the activated carbon filter cylinder 10 is fixed at the top of the right chamber of the double-chamber block 8.

[0019] In the above structure, the first water pump can export the wastewater in the water storage tank to the coarse filtration component to complete the coarse filtration of the wastewater. The filtered wastewater will be discharged into the right chamber of the double-chamber block through the liquid outlet pipe, and guided to the activated carbon filter cylinder through the liquid guiding pipe to complete the fine filtration and be collected in the collection box. When the collection box collects a certain amount of water, the second water pump exports the water source in the collection box to the left chamber of the double-chamber block, and imports it into the coarse filtration component through the circulation pipe, and then is guided to the right chamber of the double-chamber block again through the liquid outlet pipe. After being filtered in cooperation with the liquid guiding pipe and the activated carbon filter cylinder, it is imported into the collection box again for collection. Therefore, the treatment effect of the wastewater can be improved through circular filtration, and the filtration efficiency can also be improved.

[0020] Such as Figure 3As shown in the figure, the coarse filtration component includes two stainless steel filter cylinders 5 fixed on the mounting rack 1 and a double-chamber filter cylinder 6 located between the two stainless steel filter cylinders 5. The inner side of the double-chamber filter cylinder 6 has two chambers. The circulation pipe 20 and the liquid outlet pipe 7 are both communicated with the right chamber of the double-chamber filter cylinder 6. A filter layer is fixed in the left chamber, a filter layer is fixed at the center of the right chamber, and a filter layer is also fixed between the circulation pipe 20 and the liquid outlet pipe 7. The water inlet pipe of the stainless steel filter cylinder 5 on the back is communicated with the water outlet pipe of the water pump 1, and the water outlet pipe of the stainless steel filter cylinder 5 on the back is communicated with the water inlet pipe of the stainless steel filter cylinder 5 on the front. The water outlet pipe of the stainless steel filter cylinder 5 on the front is communicated with the left chamber of the double-chamber filter cylinder 6, and the water outlet pipe at the bottom of the left chamber of the double-chamber filter cylinder 6 is communicated with the water inlet pipe of the right chamber. The waste water is first introduced into the stainless steel filter cylinder on the back by the water pump 1 for filtration. After filtration, it will flow into the stainless steel filter cylinder on the front along the pipeline for re-filtration. After the filtration is completed, it will flow into the left chamber of the double-chamber filter cylinder. The waste water is re-filtered through the filter layer in the left chamber and then introduced into the right chamber. The right chamber is also filtered through the filter layer and then introduced into the right chamber of the double-chamber block through the liquid outlet pipe. Since the circulation pipe is one-way, the waste water in the right chamber cannot flow into the circulation pipe. The right chamber of the double-chamber block can guide the waste water to the activated carbon filter cylinder through the liquid guide pipe to complete the filtration and collect it in the collection box;

[0021] When the collection box reaches a certain amount, the water pump 2 pumps the water source in the collection box and guides it into the left chamber of the double-chamber block, and then guides it into the right chamber of the double-chamber filter cylinder through the circulation pipe. Therefore, the water source guided by the circulation pipe and the water source introduced into the right chamber of the double-chamber filter cylinder are both introduced into the activated carbon filter cylinder again through the liquid outlet pipe to realize the operation of circulating filtration, so as to effectively improve the filtration effect and efficiency of the water source.

[0022] As Figure 2 and 4, a water pump 15 is installed on the top of the collection tank 11. The water suction pipe of the water pump 15 extends to the bottom of the collection tank 11, and a net cylinder 16 is fixed at the bottom end of the water suction pipe. The drain pipe of the water pump 15 is communicated with one side of the activated carbon filter cylinder 10 close to the drainage. A reflux pipe 17 is fixed on one side of the activated carbon filter cylinder 10 close to the water inlet, and a impurity collection net cylinder 18 is installed at one end of the reflux pipe 17. When the filtration stops, the liquid guide pipe is closed and the reflux pipe is opened. When the water source in the collection tank is pumped out by the water pump, the water source is processed again through the net cylinder, and then introduced into the liquid outlet end of the activated carbon filter cylinder, so as to backwash the inside of the activated carbon filter cylinder. Under the backwashing action, the impurities attached to the activated carbon filter cylinder can be washed away, and then guided to the impurity collection net cylinder through the reflux pipe to filter the impurities, and then the water source is introduced into the sewage tank. Therefore, the activated carbon filter cylinder can be cleaned, avoiding the influence of too long filtration time and too many attached impurities on the filtration effect, and at the same time, the service life of the activated carbon filter cylinder can be improved.

[0023] Among them, an aeration device 12 is installed at the center of the top of the collection tank 11. The aeration pipe of the aeration device 12 extends to the bottom of the collection tank 11, and a gas filter cylinder 13 is installed on the top of the collection tank 11. By adding a flocculant into the collection tank and aerating the water source in the collection tank through the aeration device, the water source can be fully mixed with the flocculant, so that the impurities inside it form lumps, thus improving the treatment effect of the water source. When aerating, the gas in the water source in the collection tank will be filtered by the gas filter cylinder and then discharged, which can effectively avoid the harm of the discharged harmful gas to the environment and human body.

[0024] In addition, two inner net plates 14 at opposite corners on the inner side of the collection tank 11 are fixed at a right angle. The left inner net plate 14 covers the water suction end of the water pump two 19 inside, and the right inner net plate 14 covers the water suction pipe of the water pump two 19 inside. After aerating the water source through the above-mentioned aeration device, the lumps of impurities in the water source can be isolated outside by the inner net plate, avoiding blockage of the pipeline during pumping, and at the same time, the water source can be processed again in the collection tank to improve the effect.

[0025] The working principle of the above embodiment is as follows:

[0026] The wastewater is introduced into the storage water tank through a sewage guiding pipe for collection. Then, water pump 1 pumps the wastewater out and introduces it into the stainless steel filter cartridge on the back for filtration. After filtration, the wastewater is guided to the stainless steel filter cartridge on the front for further filtration. At the same time, after the filtration is completed, the wastewater also enters the left chamber of the double-chamber filter cartridge for filtration, then enters the right chamber for filtration, and then is guided to the right chamber of the double-chamber block through the liquid outlet pipe and is guided to the activated carbon filter cartridge through the liquid guiding pipe to complete the filtration of the water source. It is collected through the collection box. At the same time, a flocculant is put into the collection box and mixed by aeration through an aeration device. The impurity agglomerates are formed, and the gas generated by aeration is discharged through the gas filter. Then, the inner mesh plate can isolate the agglomerates in the water source in the collection box. When the water source reaches a certain amount, water pump 2 pumps the water source in the collection box out. Under the action of the inner mesh plate, it can prevent the internal agglomerate impurities from being pumped out. The water source is introduced into the right chamber of the double-chamber filter cartridge through the left chamber of the double-chamber block and the circulation pipe and is discharged through the liquid outlet pipe until it is filtered again through the activated carbon filter cartridge and flows into the collection box for collection, thus realizing cyclic filtration. By cyclic filtration, the filtration effect and efficiency are improved. When the filtration is completed, the liquid guiding pipe is closed, the reflux pipe is opened, and the water pump pumps the water source in the collection box out. The inner mesh plate isolates the agglomerate impurities, and at the same time, the mesh cylinder also filters the water source, and then flushes it reversely into the activated carbon filter cartridge. Therefore, the impurities in the activated carbon filter cartridge can be guided into the reflux pipe, and the impurities in the water are filtered through the impurity collection mesh cylinder, and the water source is discharged into the sewage pool to complete the cleaning of the activated carbon filter cartridge.

[0027] In summary, the filtration effect of sewage can be improved through multi-stage cyclic filtration. At the same time, the service life of the filter cartridge can be extended through backwashing, and the blockage that affects the filtration effect can be prevented. Therefore, the efficiency of sewage filtration can be effectively improved.
