Description

Technical Field

[0001] This application belongs to the field of wastewater treatment technology, specifically relating to an industrial oil-water separation device. Background Technology

[0002] In existing technologies, the compliant treatment of industrial wastewater is crucial for ensuring ecological and environmental safety and the sustainable operation of enterprises. Industrial oil-water separation devices, as core equipment in industrial wastewater pretreatment, play a vital role. They utilize the density difference between oil and water in industrial wastewater to effectively separate the oil and water, reducing the load on subsequent wastewater treatment processes, lowering pollutant emission concentrations, and helping enterprises meet environmental emission standards. Furthermore, the separated oil can be recycled and reused, improving resource utilization and creating additional economic value for enterprises. However, currently available industrial oil-water separation devices still have some significant shortcomings in practical applications.

[0003] In existing technologies, due to the complex composition of industrial oil pollution, wastewater inevitably contains oil, residues, and other substances. In low-temperature environments, the oil in these substances easily coagulates and clumps, reducing the efficiency of oil separation and causing blockages in the equipment's drainage pipes. Furthermore, existing industrial oil separation devices have structural design flaws that easily lead to the accumulation of solid impurities such as residues at the bottom of the device. Due to limited cleaning space at the bottom and the lack of specialized, convenient cleaning structures, it is difficult for workers to thoroughly clean the accumulated sediment. Over time, the sediment accumulates, not only occupying the effective volume of the device and affecting its processing capacity, but also potentially causing corrosion damage to internal components, shortening the device's lifespan, and increasing equipment replacement costs for the company.

[0004] Therefore, in order to comprehensively improve the separation efficiency, operational stability, and maintenance convenience of industrial oil-water separation devices, and reduce the operating costs and environmental pressure on enterprises, it is now urgent to improve existing industrial oil-water separation devices to meet the actual application needs in the field of industrial wastewater treatment and enhance the environmental and economic benefits of enterprises. Utility Model Content

Existing separation devices mostly employ a single separation method, resulting in low separation efficiency, inability to fully remove oil from wastewater, and difficulty in meeting discharge standards for the separated water. Furthermore, existing devices have poor adaptability to different concentrations and types of industrial oil, are prone to clogging during operation, and have high maintenance costs. Therefore, this application proposes an industrial oil separation device.

[0023] Combination Figures 1 to 6The following description further illustrates the technical solution proposed in this application. This application adopts the following technical solution: an industrial oil-water separation device, comprising a separation chamber 1, a separation chamber located within the separation chamber 1, an inlet pipe 2 located on one side of the separation chamber, an outlet pipe 39 located on the other side of the separation chamber, and a first partition 3 and a second partition 4 sequentially arranged on the separation chamber along the liquid transport direction. The first partition 3 and the second partition 4 sequentially divide the separation chamber into a settling area 5, a buffer zone 7, and a clear water zone 8 along the liquid transport direction. Liquid enters the separation chamber through the inlet pipe 2, flows sequentially through the settling area 5, the buffer zone 7, and the clear water zone 8, and then flows out through the outlet pipe 39. The second partition 4 is detachably installed in the separation chamber.

[0024] This application provides an industrial oil-water separation device, comprising a separation box, a separation chamber within the separation box, and components such as an inlet pipe, an outlet pipe, a first partition, and a second partition. Oily wastewater enters the separation chamber through the inlet pipe, flows sequentially through a settling zone, a buffer zone, and a clean water zone, and then exits through the outlet pipe. The second partition is detachable. By dividing the separation chamber into multiple areas, the oil and water layers can be fully separated after the oily wastewater enters the separation chamber, significantly improving the oil separation efficiency in wastewater. Furthermore, the detachable second partition within the separation box facilitates cleaning and maintenance of the device, effectively reducing equipment maintenance costs. It features a simple and reasonable structure, strong adaptability, ability to meet the separation needs of different oil specifications, convenient operation, low implementation cost, and ease of widespread implementation.

[0025] In actual implementation, industrial wastewater containing oil enters the separation chamber inside the separation tank 1 through the inlet pipe 2. After entering the separation chamber, the liquid first flows into the settling zone 5, which is separated by the first partition 3. Due to the density difference between oil and water (oil is usually less dense than water), under static conditions, the oil gradually rises to the surface of the liquid, forming an oil layer; while the water sinks to the lower layer, completing the initial oil-water stratification. After the settling separation is completed, the wastewater enters the buffer zone 7 through the first outlet 30. The buffer zone is formed by the first partition 3 and the second partition 4. Its main function is to eliminate fluctuations in the water flow in the settling zone and prevent the separated oil from being mixed back into the water due to water flow impact. In addition, the buffer zone can also regulate the water volume. When the inflow fluctuates, the buffer zone can temporarily store excess water while eliminating the impact fluctuations in the water flow in the settling zone, preventing the separated oil from being mixed back into the water, and ensuring stable effluent from the subsequent clear water zone. After being buffered by the buffer zone, the wastewater will pass through the second partition 4 and enter the clear water zone 8. The main function of the clear water zone is to store the separated clear water and discharge it through the outlet pipe 39.

[0026] In this embodiment, one end of the first partition 3 is located at the top of the separation chamber, and the other end of the first partition 3 and the bottom of the separation chamber are provided with a first liquid outlet 30. Liquid flows from the first liquid outlet 30 into the buffer zone 7.

[0027] In this embodiment, one end of the second partition 4 is located at the bottom of the separation chamber, and the other end of the second partition 4 is located at the top of the separation chamber with a second liquid outlet 40. The buffer zone 7 is located between the first partition 3 and the second partition 4, and the liquid flows from the second liquid outlet 40 into the clear water zone 8.

[0028] In actual implementation, industrial wastewater containing oil enters the separation chamber of the separation tank 1 through the inlet pipe 2 and first flows to the settling zone 5 defined by the first partition 3. One end of the first partition 3 is fixed to the top of the separation chamber, and the other end retains the first outlet 30 at the bottom of the chamber. The oily wastewater forms a downward flow trend in the settling zone 5. When the liquid is introduced, the wastewater first accumulates in the upper part of the settling zone. As the liquid level rises, the water gradually seeps downward, avoiding the wastewater directly impacting the bottom of the chamber and causing the deposited impurities to surge. At the same time, it creates a stable initial environment for the oil to float. In the settling zone 5, the wastewater obtains sufficient residence time and achieves stratification based on the density difference between oil and water: the less dense oil (such as mineral oil, vegetable oil, etc.) gradually floats to the liquid surface and forms a stable oil layer; the more dense water sinks to the lower layer. When the water level in the settling zone 5 continues to rise to the height of the first outlet 30, the clear water in the lower layer flows into the buffer zone 7 through the first outlet 30. Because the first outlet 30 is located at the bottom of the chamber, it only allows the lower layer of clean water to pass through, effectively preventing the upper oil layer from entering the buffer zone and achieving the effect of water-oil separation. The clean water flowing into the buffer zone 7 from the first outlet 30 is forced to form an upward flow path due to the obstruction of the second baffle 4. During this process, the buffer zone 7 can eliminate the impact of water flowing in from the settling area, preventing the separated oil droplets from mixing back into the water. The clean water, after secondary oil removal in the buffer zone 7, rises to the height of the second outlet 40 and flows into the clean water zone 8 from the second outlet 40. The second outlet 40 is located at the top of the chamber, only allowing the upper layer of clean water in the buffer zone 7 to pass through, further intercepting any impurities and residual oil droplets that may accumulate at the bottom. The clean water zone 8 serves as the final clean water storage and discharge area, where qualified clean water can be discharged through the outlet pipe 39 for subsequent recycling (such as workshop cleaning and greening irrigation) or for compliant discharge.

[0029] In this embodiment, the width of the static area 5 is defined as A, the width of the buffer zone 7 is defined as B, and the width of the clear water area 8 is defined as C. A, B, and C satisfy the following relationship: 4≤A / B≤5.5, 6.5≤A / C≤8.

[0030] In actual implementation, A / B=5.5 and A / C=7.5. This device can effectively improve the degree of oil-water separation and the purification efficiency of oily wastewater by designing the width of the settling zone, buffer zone and clear water zone.

[0031] In this embodiment, a connecting component is also provided between the second partition 4 and the separation box 1. The connecting component includes slots on both sides of the inner wall of the separation box 1 and blocks on both sides of the second partition 4. The blocks can be matched and extended into the slots so that the second partition 4 can be detachably provided to the separation box 1.

[0032] In actual implementation, the gap between the card block and the card slot is usually controlled at 0.1mm-0.2mm, and a rubber sealing ring is provided on the surface of the card block to prevent oily wastewater in the buffer zone from seeping directly into the clean water area through the gap between the partition and the tank without being filtered by the second outlet, thus avoiding secondary pollution and ensuring stable effluent quality.

[0033] In actual implementation, by detachably mounting the second partition plate on the separation box, after removing the second partition plate 4, the oil and impurities attached to the surface can be directly rinsed off; after cleaning, align the locking blocks on both sides of the second partition plate 4 with the locking slots of the separation box 1, insert them vertically downwards until the bottom of the locking block contacts the bottom of the locking slot, thereby achieving rapid reset of the partition plate, and the device can be put back into operation.

[0034] In this embodiment, a filter assembly 9 is also provided between the first partition 3 and the separation chamber 1. The filter assembly 9 is located above the static area 5. One end of the filter assembly 9 is located on the side wall of the separation chamber, and the other end is located on the first partition 3. The filter assembly 9 is used to filter solid impurities in the liquid.

[0035] In actual implementation, wastewater flows in from the inlet side of the filter assembly, solid impurities are intercepted by the filter assembly and remain on the surface or inside the filter assembly; while the oily wastewater with impurities removed flows smoothly through the filter assembly into the settling zone 5, preventing impurities from entering the subsequent separation stage with the water flow.

[0036] In this embodiment, the filter assembly 9 includes a bracket 90 with one end disposed on the side wall of the separation chamber and the other end disposed on the first partition 3, and a filter screen assembly 91 mounted on the bracket 90.

[0037] In this embodiment, the bracket 90 includes a frame 92, a filter port 93 disposed on the frame 92, and a support groove 95 disposed on the frame 92 and located on both sides of the filter port 93. The filter port 93 is provided at intervals along the length direction of the frame 92. The filter mesh group 91 includes a plurality of filter meshes 94, and the filter meshes 94 are matched and mounted on the support grooves 95.

[0038] In this embodiment, the diameter of the inlet pipe 2 is defined as r, and the diameter of the outlet pipe 39 is defined as R. The relationship between R and r is as follows: 2≤R / r≤3.5.

[0039] This application provides an industrial oil-water separation device, comprising a separation box, a separation chamber within the separation box, and components such as an inlet pipe, an outlet pipe, a first partition, and a second partition. Oily wastewater enters the separation chamber through the inlet pipe, flows sequentially through a settling zone, a buffer zone, and a clean water zone, and then exits through the outlet pipe. The second partition is detachable. By dividing the separation chamber into multiple areas, the oil and water layers can be fully separated after the oily wastewater enters the separation chamber, significantly improving the oil separation efficiency in wastewater. Furthermore, the detachable second partition within the separation box facilitates cleaning and maintenance of the device, effectively reducing equipment maintenance costs. It features a simple and reasonable structure, strong adaptability, ability to meet the separation needs of different oil specifications, convenient operation, low implementation cost, and ease of widespread implementation.
