Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the utility model. Figure 1 to the drawings Figure 4 The utility model is described in detail as follows:

[0035] As Figures 1-4 The utility model provides a flat flow type sludge pool suitable for radioactive wastewater production, which can be used for treating radioactive sludge wastewater with high water content, and comprises:

[0036] The sludge pool body 1 is a closed container, which is divided into a sludge guide area 10 and a sludge collection area 11 arranged at the end of the sludge guide area 10, so as to realize sludge guide and collection; wherein the sludge guide area 10 realizes sludge guide, the sludge collection area 11 is used for collecting sludge, and the sludge on the sludge guide area 10 is transported into the sludge collection area 11, and a sludge pump 111 is arranged outside the sludge collection area 11, so that the sludge in the sludge collection area 11 is transported to the next process by the sludge pump 111 regularly, and sludge-water separation treatment is carried out; the sludge pool body 1 is divided into areas, so that the equipment and operation of each area are relatively independent, which is convenient for maintenance and management, if the sludge pump 111 fails, the sludge collection area 11 can be repaired alone, without affecting the normal operation of the sludge guide area 10; at the same time, the sludge is collected in the sludge collection area 11 and transported regularly by the sludge pump 111, so that a more stable sludge treatment process can be realized; it should be noted that a feeding interface 13 for feeding and a discharging interface for discharging are arranged on the sludge pool body 1, and the discharging interface is connected with the sludge pump 111, so that the sludge is pumped out through the discharging interface;

[0037] The stirring device 2 is arranged above the sludge guide area 10 of the sludge pool body 1, and is used for stirring the sludge above the sludge guide area 10, so as to avoid rapid deposition of the sludge in the sludge pool body 1;

[0038] The mud removal device 3 is arranged in the sludge guide area 10 of the sludge pool body 1, and is used for scraping the sludge in the sludge guide area 10;

[0039] The air pressure purging device 4 is arranged at the bottom of both sides of the sludge guide area 10 of the sludge pool body 1, the air pressure pipeline 40 of the air pressure purging device 4 extends into the sludge pool body 1, so as to realize the purging function of the sludge in the sludge pool body 1; for the radioactive wastewater treatment system with small treatment capacity and intermittent sedimentation reaction, the air pressure purging device can effectively maintain the normal operation of the sludge pool.

[0040] The tail gas treatment device 5 is connected with the exhaust port 12 arranged at the top of the sludge pool body 1; since the sludge will produce foul odor after being stored in the sealed container sludge pool body 1 for a period of time, which greatly affects the operation environment of the operating personnel, after the tail gas treatment device 5 is arranged, the foul odor generated will be introduced into the tail gas treatment device 5 through the exhaust port 12 arranged at the top of the sludge pool body 1, and then purified.

[0041] The utility model discloses a horizontal flow type sludge pool suitable for radioactive wastewater production, when working, the insoluble precipitate produced in the radioactive wastewater treatment process enters the sludge pool body 1 as sludge. The sludge flows to the sludge collection area 11 through the flow guiding effect in the sludge flow guiding area 10. The sludge collection area 11 collects the sludge from the sludge flow guiding area 10, and utilizes the sludge pump 111 to regularly transfer the sludge to the next process for sludge-water separation treatment.

[0042] Correspondingly, the stirring device 2 continuously stirs the sludge above the sludge flow guiding area 10 to prevent the sludge from rapidly depositing, so that the flowability of the sludge can be maintained, and the subsequent flow guiding and treatment are facilitated. If there is still sludge in the sludge flow guiding area 1, the sludge removal device 3 is started, the sludge removal device 3 scrapes the sludge in the sludge flow guiding area 10 to further promote the flow and cleaning of the sludge and prevent the sludge from accumulating in the sludge flow guiding area 10. At the same time, the air pressure blowing device 4 can also be started, the air pressure blowing device 4 sends compressed air into the sludge pool body from the bottom of both sides of the sludge flow guiding area 10 through the air pressure pipeline 40 to blow the sludge, which can prevent the sludge from accumulating and blocking at the bottom of the pool and also help to maintain the flowability of the sludge.

[0043] In addition, due to the particularity of radioactive wastewater treatment, the sludge may contain a certain dose of radioactivity, and the closed sludge pool body 1 is prone to produce foul odor. The tail gas treatment device 5 can purify the foul odor gas, greatly improve the operation environment of the operating personnel and reduce the influence on the health of the personnel.

[0044] In summary, the horizontal flow type sludge pool adopts airtight design to adapt to the needs of radioactive wastewater treatment, and through the stirring, sludge removal, air pressure blowing and other devices, the sludge treatment is ensured to be efficient and stable, the blockage and deposition are prevented, the sludge storage and self-cleaning functions are realized; the tail gas treatment device 5 is also provided to improve the working environment and protect the health of the personnel.

[0045] Further, in some embodiments, the sludge diversion area 10 of the sludge pool body 1 includes a vertical diversion area 101 away from the sludge collection area 11, and a horizontal diversion area 102 close to the sludge collection area 11. Both the vertical diversion area 101 and the horizontal diversion area 102 have slopes, and the slope of the vertical diversion area 101 is greater than that of the horizontal diversion area 102. The vertical diversion area 101 has a large slope, which can use gravity to make the sludge flow faster from high to low into the horizontal diversion area 102. The large slope can provide a large sliding force to accelerate the transfer of sludge. The horizontal diversion area 101 also has a certain slope, which helps the sludge continue to flow to the sludge collection area 11. Although the slope is small, it can ensure that the sludge can also stably advance in the horizontal direction and avoid stagnation. The large slope of the vertical diversion area 101 and the small slope of the horizontal diversion area 102 cooperate with each other to make the sludge flow smoothly at different stages, reduce the accumulation at the bottom of the pool, avoid the need for frequent manual cleaning due to sludge accumulation, and reduce maintenance costs and operation difficulty. In addition, for the treatment of radioactive wastewater, it is necessary to minimize the contact and intervention of operators. This sloped design can achieve automatic diversion of sludge, reduce the need for manual operation, and reduce the risk of radioactive contamination of operators.

[0046] More specifically, in this embodiment, the sludge pool body 1 is a reinforced concrete structure, and the inner wall of the sludge pool body 1 and the upper surface of the sludge diversion area 10 are provided with an acid and alkali corrosion resistant and leakage resistant coating, so that the inner wall of the sludge pool body 1 and the sludge diversion area 10 have the functions of acid and alkali corrosion resistance and leakage resistance. In the treatment of radioactive wastewater, the wastewater may have different degrees of acidity and alkalinity. The acid and alkali corrosion resistant coating can effectively protect the sludge pool body 1 and the sludge diversion area 10, avoid damage to the equipment structure due to acid and alkali corrosion, and thus prolong the service life of the sludge pool. At the same time, the upper surface of the sludge diversion area 10 requires to be smooth and flat to improve the efficiency of sludge diversion.

[0047] Further, in some embodiments, the stirring device 2 includes a stirring power mechanism and a plurality of stirring paddle mechanisms 20 connected to the stirring power mechanism.

[0048] The stirring power mechanism provides sufficient power to drive the stirring paddle, ensures the stirring intensity and effect, and improves the flowability of the sludge. The stirring paddle mechanism 20 extends into the sludge pool body 1 from the top of the sludge pool body 1, realizes the stirring of the sludge on the sludge flow guide area 10, and prevents the sludge from rapidly depositing in the flow guide area. A plurality of stirring paddle mechanisms 20 can stir the sludge at different positions, expand the stirring range, make the sludge in the sludge flow guide area 10 be more fully stirred, and effectively prevent the sludge from rapidly depositing. At the same time, the stirring device 2 can reduce the need for manual stirring of the sludge, reduce the risk of operators contacting radioactive substances, and improve the safety of operation.

[0049] It should be noted that the number and type of the stirring paddle mechanism 20 in the utility model are not specifically limited; for example, the number of the stirring paddle mechanism 20 and the layout of the stirring paddle mechanism 20 can be determined according to the area of the sludge pool body 1 to realize omnidirectional stirring of the sludge pool body 1. The stirring paddle mechanism 20 can be a single-blade stirring paddle mechanism or a multi-blade stirring paddle mechanism, which can be designed and selected by a person skilled in the art according to actual conditions and belongs to the protection scope of the utility model.

[0050] Further, in some specific embodiments, the sludge removing device 3 comprises a sludge removing power mechanism 30 and a sludge scraping plate 31 connected with the sludge removing power mechanism 30, the sludge scraping plate 31 is arranged along the width direction of the sludge flow guide area 10, and is used for scraping the sludge on the sludge flow guide area 10 to the sludge collecting area 11. When in use, the operator does not need to enter the sludge pool to perform the sludge removing operation, thereby avoiding contacting the sludge that may contain radioactive substances and reducing the risk of radiation injury of the operator. Meanwhile, a sludge removing device 3 can also be arranged in the sludge collecting area 11, which can be designed by referring to the sludge removing device in the sludge flow guide area 10. The sludge scraping devices 3 are arranged in the two flow guide areas respectively to realize the sludge scraping and collecting functions and avoid sludge accumulation.

[0051] Further, in the embodiment, the sludge scraping plate 31 has a slope surface, the slope direction of the slope surface is the same as the slope direction of the sludge flow guide area, so that the sludge scraping plate 31 has a triangular structure, as shown in Figure 2 The sludge scraping plate 31 with the slope surface and the triangular structure has good sludge scraping performance, can scrape the sludge from the surface of the sludge flow guide area, and improves the efficiency and completeness of the sludge scraping. Meanwhile, the triangular structure is relatively stable and can withstand the pressure and friction force in the sludge scraping process, so that the sludge scraping plate 31 is not easy to deform or be damaged under the action of the sludge scraping power mechanism 30, and the long-term stable operation of the sludge removing device 3 is ensured.

[0052] Further, in some specific embodiments, the compressed air blowing device 4 comprises an air compressor 41, a first air tank 42, an oil removal filter 43, a second air tank 44, a pressure reducing valve group 45, and a compressed air pipeline 40 connected in sequence. Through the coordinated operation of the air compressor 41, the first air tank 42, the oil removal filter 43, the second air tank 44, the pressure reducing valve group 45, and the compressed air pipeline 40, when there is no blockage, the air compressor 41 can be turned on to play a bubbling effect, which can prevent the accumulation and blockage of sludge at the bottom of the pool, maintain the fluidity of the sludge, and enable the sludge to flow smoothly to the sludge collection area 11, thereby improving the efficiency of sludge treatment. Since the mud removal device 3 has a blind area in the operation track of the mud scraping, the compressed air pipeline 40 on both sides of the sludge pool can be used for blowing and mud removal at this time.

[0053] The air tank can alleviate the fluctuation of the output pressure of the air compressor 41, protect the downstream equipment from pressure impact, and prolong the service life of the equipment. The oil removal filter 43 removes oil in the compressed air to prevent corrosion and damage to the equipment and ensure stable operation of the equipment. At the same time, the pressure reducing valve group 45 can adjust the pressure of the compressed air according to the actual situation to adapt to different sludge treatment requirements and working conditions. It should be noted that the pressure of the bubbling compressed air should be less than 0.3 MPa, and in this embodiment, the pressure of the mud removal compressed air can be adjusted to 0.6 MPa by the pressure reducing valve group 45.

[0054] In some more specific embodiments, the compressed air pipeline 40 has a first output port and a second output port at the end. The first output port extends into the sludge pool body 1 and adjusts the pressure by the pressure reducing valve group 45 to achieve compressed air bubbling. The effect of bubbling is to prevent the deposition of sludge on the pool bottom, thereby reducing the frequency of personnel dredging. The second output port is connected to the reverse blowing interface for reverse blowing of the sludge; when the sludge is deposited at both ends of the sludge pool body 1, the pressure can be adjusted to perform the dredging operation.

[0055] In some more specific embodiments, the advection type sludge pool further comprises a flushing device 6, which comprises a flushing pipeline and a high-pressure pump 60 installed on the flushing pipeline. The end of the flushing pipeline is in communication with the compressed air pipeline 40. When the sludge deposited in the sludge flow guide area 10 still has no effect through the compressed air blowing device 4, the flushing device 6 can be used to flush the sludge pool; after being pressurized by the high-pressure pump 60, the compressed air pipeline 40 of the compressed air blowing device 4 can be used to flush the bottom of the sludge pool to achieve the effect of removing the sludge. Through the combination of compressed air blowing and high-pressure flushing, stubborn sludge can be removed more effectively, and the success rate of sludge removal can be improved.

[0056] Further, in some specific embodiments, the tail gas treatment device 5 comprises a tail gas filter 50 and an exhaust fan 51, the input end of the tail gas filter 50 is connected with the exhaust vents opened on the top of the sludge pool body 1, and the output end is connected with the exhaust fan 51. Under the action of the exhaust fan 51, the foul smell generated in the sludge pool body 1 is led out through the exhaust vents arranged on the top of the sludge pool body 1, and is discharged after being purified by the tail gas filter 50. In this embodiment, the tail gas filter 50 can preferably be a multi-stage filter to enhance the filtering effect.

[0057] Further, in some specific embodiments, a manhole can also be arranged on the sludge pool body 1 to facilitate the maintenance operation of the staff, but it should be noted that the staff must wear appropriate protective articles when working in the closed space containing radioactive waste liquid, and can only enter after obtaining approval after confirming the oxygen concentration and ventilation environment. Of course, a moisture-proof lamp should also be arranged in the sludge pool body 1 to achieve the lighting function.

[0058] Further, in some specific embodiments, a camera assembly can also be arranged in the sludge pool body 1 to monitor the condition in the sludge pool body 1 in real time. It should be noted that the specific structure of the camera assembly is not limited in the present application, and can be designed and selected by the person skilled in the art according to the actual situation.
