Description

[0002] Circulating water refers to industrial production water that is used once and then properly treated for reuse. This water is mainly used for cooling, washing and other processes. The quality of circulating water is usually affected by factors such as raw water, dirt generated during use, and treatment methods. In industrial production, the water quality requirements for circulating water are relatively high because it directly affects the quality of the product and production efficiency. If the circulating water contains too many impurities or harmful substances, it may cause equipment corrosion, blockage and other problems, thereby affecting production efficiency and product quality. Therefore, effective treatment of circulating water and maintaining good water quality are very important parts of industrial production.

[0003] At present, the treatment of circulating water is to remove impurities in the water through filtration, sedimentation and other methods, so as to achieve the purpose of purifying the water quality.

Most of them are treated by adding acid, which requires the purchase of independent acid addition tanks and mixing tanks. In order to reduce the cost of technical improvement, the existing equipment is used for transformation to achieve multi-functionality of one tank. Utility Model Content

DETAILED DESCRIPTION

[0019] See also Figures 1 to 3In the embodiment of the utility model, the circulating water acidification device includes a transfer tank 1, which is provided with a liquid level meter 2, an input end 4 and a breathing valve 5. The bottom of the liquid level meter 2 is connected to the output end. An overflow plate 15 and a partition plate 14 are provided inside the transfer tank 1, and the interior thereof is divided into three tank bodies, namely a sedimentation tank, a buffer tank and a fusion tank. The input end 4 injects circulating water into the sedimentation tank, and the circulating water overflows from the overflow plate 15 to the buffer tank after sedimentation. The bottom of the buffer tank is connected to a water pump 11 through a circulating water pipeline 7, and the water pump 11 is connected to the fusion tank through an acid distribution pipeline 10. The acid distribution pipeline 10 is connected to an acid distribution tank 3 through an acid distribution pipeline 8, and the acid distribution tank 3 transports an acid solution to the acid distribution pipeline 8 through an acid distribution pump 6. The transfer tank 1 realizes the functions of precipitation, impurity removal, buffering and mixing. By modifying the transfer tank, an acid distribution tank 3 and an acid distribution pump 6 are added, and the acid distribution pump 6 controls the acid addition ratio by adjusting the power. The transfer tank 1 is divided into a sedimentation tank, a buffer tank and a fusion tank by an overflow plate 15 and a partition plate 14. The circulating water enters the sedimentation tank through the input end 4. The heavy impurities in the circulating water are precipitated to the bottom, and the circulating water enters the buffer tank by overflow, which not only achieves the purpose of buffering the pressure fluctuation of the circulating water, but also performs impurity precipitation and separation. The circulating water in the buffer tank is extracted from the bottom, sent to the acid preparation pipeline 10 for preparation through a water pump 11, enters the fusion tank for mixing, and finally sends the circulating liquid out through the output end for reuse. This technical solution transforms the transfer tank 1 on the existing circulation line, and prepares the acid preparation tank 3 and the acid preparation pump 6 for acid preparation, which saves the cost of circulating water acid preparation transformation, and efficiently improves the existing equipment. It is reasonably designed and has economic benefits, and at the same time realizes the functions of buffering circulating water, precipitation and impurity removal, proportioning and mixing.

[0020] In a preferred embodiment, a sewage outlet 17 is provided at the bottom of the sedimentation tank, and a circulating water return sewage pipeline 18 is provided at the bottom of the buffer tank. The sewage outlet 17 and the circulating water return sewage pipeline 18 are connected to a sewage pump 21 through a three-way valve 20. A sewage pipe 9 is installed at the output end of the sewage pump 21. The three-way valve 20 is rotated to adjust the switching of the sewage outlet 17 and the circulating water return sewage pipeline 18. When the impurities precipitated at the bottom of the sedimentation tank need to be discharged, the three-way valve 20 is rotated to adjust the connection with the sewage outlet 17, and the sewage pump 21 extracts the sewage and discharges it through the sewage pipe 9. When the three-way valve 20 is rotated to adjust the connection with the circulating water return sewage pipeline 18, the circulating water or secondary sediment in the buffer tank is cleaned.

[0021] In a preferred embodiment, the sewage pipe 9 is connected to the circulating water return pipeline 19 through a three-way control valve, and the other end of the circulating water return pipeline 19 is connected to the buffer tank. After the impurities in the sedimentation tank are discharged, if the sedimentation tank needs to be cleaned, the three-way control valve is rotated and adjusted to connect with the circulating water return pipeline 19, and the circulating water from the sedimentation tank after the impurities are discharged is directly sent to the buffer tank without overflow, thereby reducing the discharge and waste of circulating water. The top of the buffer tank faces the observation well, and other additives can be added to the observation well. If mixing is required, it can be connected to the circulating water return sewage pipeline 18 through the three-way valve 20. The three-way control valve is rotated and adjusted to connect with the circulating water return pipeline 19, and the internal circulation is carried out by pumping liquid through the sewage pump 21.

[0022] In a preferred embodiment, the circulating water pipeline 7 penetrates into the buffer tank and extends upward to a height of at least ten centimeters. The upward extension of the circulating water pipeline 7 can effectively prevent impurities in the buffer tank from being sucked into the circulating water pipeline 7, thereby improving the quality of the circulating water. When the circulating water in the buffer tank needs to be drained, the circulating water below the circulating water pipeline 7 will be discharged as sewage.

[0023] In a preferred embodiment, a spray device 13 is installed at the output end of the acid preparation pipeline 10, and a sputtering plate 22 located on the spraying track of the spray device 13 is installed in the fusion tank. When the liquid output by the acid preparation pipeline 10 enters the fusion tank, the injection position is fixed, resulting in slow dispersion and mixing speeds of the newly entered mixed liquid and the mixed liquid in the fusion tank. For this reason, the mixing effect of the mixed liquid is improved by spraying and sputtering, and the injection method is uniformly dispersed, and effective mixing can be achieved without stirring. For the solid auxiliary agent added to the buffer tank, the liquid mixing is more uniform after spraying and sputtering.

[0024] In a preferred embodiment, the tops of the buffer tank and the fusion tank are interconnected, and a guide plate 12 is installed in the transfer tank 1 at the connection between the buffer tank and the fusion tank to prevent the splashing liquid from returning to the buffer tank. This arrangement allows the sedimentation tank, the buffer tank, and the fusion tank to be interconnected, and the air pressure is balanced. The entire air pressure in the transfer tank 1 can be balanced through the breathing valve 5.

[0025] In a preferred embodiment, a funnel-shaped bottom plate 16 is provided at the bottom of the sedimentation tank, and a sewage outlet 17 is connected to the lowest end of the bottom plate 16. This design is to improve the efficiency and effect of sewage discharge so that impurities can be discharged.

[0026] It should be noted that the above embodiments all belong to the same utility model concept, and the description of each embodiment has its own focus. For matters that are not described in detail in some embodiments, reference can be made to the description in other embodiments.

[0027] The above-mentioned embodiments only express the implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
