Description

Technical Field

[0001] This utility model relates to the field of oil mist collection technology, and in particular to a condensation-type oil mist collection and treatment device. Background Technology

[0002] Against the backdrop of rapid development in modern manufacturing, industrial processes such as machining and metal cutting generate large amounts of oil mist pollutants. This oil mist not only harms the health of operators but also pollutes the production environment. Therefore, efficient oil mist treatment technology has become a key requirement in the field of industrial environmental protection. However, existing traditional oil mist treatment devices have many technical shortcomings and are unable to meet the environmental protection requirements and operational needs of modern industrial production. In terms of oil mist treatment efficiency, traditional devices perform poorly when dealing with high concentrations of oil mist. The core problems lie in low condensation efficiency and uneven airflow distribution, leading to incomplete oil mist liquefaction. The internal airflow channel design of traditional devices is unreasonable; high-concentration oil mist cannot evenly contact the condensation components after entering the device, causing oil mist to accumulate in some areas and fail to cool sufficiently, resulting in poor liquefaction and separation effects. This directly leads to excessive concentrations of residual oil mist and particulate matter in the emitted air, making it difficult to meet increasingly stringent environmental regulations. This problem is particularly pronounced in scenarios involving high concentrations of oil mist, such as precision machining and heavy machinery, exposing companies to environmental compliance risks. Furthermore, the fixed structure design of traditional equipment has significant limitations. The fixed structure leads to complex maintenance processes, making internal components difficult to disassemble and clean, requiring frequent shutdowns for each maintenance operation, severely impacting production continuity. Additionally, the oil recovery process is poorly designed, failing to efficiently collect the liquefied oil mist, leaving large amounts of oil residue inside the equipment, wasting resources and increasing cleaning frequency. Frequent maintenance shutdowns not only increase labor and equipment operating costs but also reduce production efficiency. Moreover, the fixed structure cannot adjust processing parameters according to different operating conditions, making it difficult to adapt to diverse scenarios with different processing techniques and oil mist concentrations, thus limiting the applicability and practical application value of the equipment.

[0003] The following technical problems exist in the existing technology:

[0004] 1. Traditional oil mist treatment devices have low condensation efficiency and uneven airflow distribution when dealing with high concentrations of oil mist, resulting in incomplete oil mist liquefaction, poor separation effect, and excessive residual oil mist and particulate matter in the exhaust air, making it difficult to meet strict environmental protection standards.

[0005] 2. Traditional devices use a fixed structure, which is complex to maintain, requires frequent shutdowns for cleaning, has low oil recovery efficiency, results in resource waste and high operating costs, and is difficult to adapt to diverse scenarios. Utility Model Content

The oil mist treatment tank 1 is equipped with an exhaust port 10 at the top. As the core container, the oil mist treatment tank 1 houses the treatment components and provides a closed treatment space. The tank shell 2 is welded to the surface of the tank to ensure stability and adapt to industrial vibration. The arc-shaped guide seat 7 guides the oil mist air and liquefied oil droplets to the annular collection tank 8. The annular collection tank 8 is connected to the liquid outlet pipe 9 to collect and discharge the oil. The positioning ring 11 is welded inside the tank to fix the centrifugal motor 16 and install the multi-layer adsorption component 14. The centrifugal motor 16 drives the dispersing blades 17 to generate centrifugal force to separate the liquefied oil droplets. The air inlet 4 introduces the oil mist air, and the exhaust port 10 discharges the purified air. The oil mist air enters from the air inlet 4 and rises along the arc-shaped guide seat 7. The condensation component 15 lowers the temperature to liquefy the oil mist. The centrifugal motor 16 drives the dispersing blades 17 to throw the liquefied oil droplets toward the tank wall.

[0041] Reference Figures 1 to 8 Based on the content of the above specific embodiments, the following content is further disclosed:

[0042] When the condenser assembly 15 is in use, the compressor 1502 drives the refrigerant circulation inside the condenser tube 1501, which typically uses Freon or environmentally friendly refrigerant. The refrigerant absorbs heat through evaporation, reducing the temperature of the tank wall and causing the oil and gas molecules in the oil mist air to condense into droplets. The first air guide hole 1506 provides the main flow of cold air, and the second air guide hole 1507 supplements the local airflow. The staggered distribution forms a uniform cold air flow field, which accelerates the liquefaction of oil mist. The controller 1503 monitors the temperature inside the tank, the concentration of oil mist, or the airflow speed through built-in sensors and dynamically adjusts the power of the compressor 1502 and the airflow of the air guide holes to ensure a balance between condensation efficiency and energy consumption. The protective cover 1505 isolates the external environment and extends the life of the assembly. The controller 1503 starts the compressor 1502, and the refrigerant in the condenser 1501 begins to circulate, reducing the tank wall temperature. Cold air enters the tank at a high flow rate through the first air guide 1506 and a low flow rate through the second air guide 1507, making full contact with the oil mist air and promoting rapid condensation of oil and gas molecules. The controller 1503 adjusts the operating frequency of the compressor 1502 and the airflow distribution through the air guides based on real-time temperature and airflow feedback to optimize the condensation effect. The liquefied oil droplets are separated under the action of the centrifugal motor 16, and the remaining air continues to flow upward. The condenser assembly 15 is the core link of oil mist liquefaction. It works in conjunction with the arc-shaped guide seat 7 to guide the oil mist air through the condensation area and works with the centrifugal motor 16 and the dispersing blades 17 to accelerate the separation of liquefied oil droplets. The air guide is located between the centrifugal motor 16 and the arc-shaped guide seat 7 to optimize the distribution of cold air and ensure uniform cooling of the oil mist. The controller 1503 is integrated with the automation system of the entire device to improve energy efficiency. The protective cover 1505 ensures the stability of the condenser assembly 15 in the industrial environment. The condenser assembly 15 provides liquefied oil droplets for subsequent centrifugal separation, and works in conjunction with the annular collection tank 8 and the outlet pipe 9 to complete oil collection. It also works with the multi-layer adsorption assembly 14 to ensure air purification. It efficiently condenses oil mist, provides uniform airflow distribution, and the controller 1503 enables energy-saving automation. The protective cover 1505 enhances durability, and the staggered air guide holes reduce turbulence and improve condensation efficiency, making it suitable for complex industrial scenarios.

[0043] The multi-layer adsorption component 14 is located at the top of the positioning ring 11. It captures residual fine oil mist particles and volatile organic compounds (VOCs) after condensation and centrifugal separation using multi-layer adsorption materials, ensuring that the emitted air meets environmental standards. The limiting ring 12 secures the adsorption component via a threaded connection, facilitating disassembly and maintenance. A flow divider 13 is distributed on the top surface of the limiting ring 12, guiding the purified air to flow evenly towards the exhaust port 10, reducing airflow resistance. The exhaust port 10 discharges clean air, completing the treatment process. In practical use, based on common technologies in the oil mist treatment field, it is speculated that the multi-layer adsorption component 14 consists of multiple layers of adsorption materials with different functions, typically including: a primary filtration layer, such as a high-density fiber mesh or metal mesh, capturing larger particles such as incompletely liquefied oil droplets or dust; an activated carbon layer, adsorbing fine oil mist particles and VOCs, utilizing the high specific surface area and pore structure of activated carbon; a molecular sieve layer, selectively adsorbing specific volatile gases such as low-molecular-weight VOCs; and a fine filtration layer, such as HEPA filter media, further removing submicron-sized particles. These layers are arranged in order of airflow direction, with the primary filter layer close to the positioning ring 11 and the fine filter layer close to the flow divider 13, forming a gradient filtration structure to improve adsorption efficiency.

[0044] Purified air, after condensation and centrifugal separation, enters the multi-layer adsorption assembly 14. The primary filter layer intercepts larger particles, while the activated carbon layer and molecular sieve layer adsorb tiny oil mists and VOCs. The fine filter layer removes residual particles. The limiting ring 12 fixes the materials of each layer to prevent displacement. The flow divider 13 optimizes the airflow distribution, reduces resistance, and ensures that the air flows smoothly to the exhaust port 10. The exhaust port 10 discharges clean air that meets environmental standards. The condensed and centrifugally separated air enters the multi-layer adsorption assembly 14 from the top of the positioning ring 11. The air passes sequentially through the primary filter layer, activated carbon layer, molecular sieve layer, and fine filter layer. Residual particles and VOCs are adsorbed layer by layer. The flow divider 13 guides the purified air to flow evenly to the exhaust port 10, and the clean air is discharged through the exhaust port 10. The limiting ring 12 ensures the stable operation of the assembly.

[0045] The multi-layer adsorption component 14 serves as the final purification stage after condensation and centrifugal separation. It works in conjunction with the condensation component 15 and the centrifugal motor 16 to ensure that the exhaust air meets high-precision purification standards. The gradient adsorption structure improves the collection efficiency by filtering from primary to fine filtration, covering pollutants of different particle sizes and chemical properties. The limiting ring 12 is threadedly connected to the oil mist treatment tank 1, forming a stable structure with the tank body and the positioning ring 11, which is convenient for maintenance. The diverter plate 13 works with the exhaust port 10 to optimize airflow discharge and forms a complete airflow path with the airflow guidance function of the arc-shaped guide seat 7.

[0046] In summary:

[0047] 1. This system employs a multi-stage treatment mechanism involving condensation, centrifugal separation, and multi-layer adsorption to achieve highly efficient oil mist purification. The condensation component 15 utilizes staggered air guide holes to form a uniform cold air flow field, which, combined with the arc-shaped guide seat 7, optimizes the airflow path and significantly improves the oil mist liquefaction efficiency. The centrifugal motor 16 drives the dispersing blades 17 to quickly separate liquefied oil droplets, which slide along the guide seat to the annular collection tank 8 for discharge. The multi-layer adsorption component 14 captures fine particles and volatile organic compounds, ensuring clean emissions. The controller 1503 dynamically adjusts the condensation and airflow parameters to reduce energy consumption, and the protective cover 1505 enhances the durability of the components. Compared with traditional oil mist treatment devices, this design improves treatment efficiency and reduces energy consumption through multi-stage coordination and control. It is suitable for high-concentration oil mist scenarios such as hydropower station units, reducing environmental pollution and extending equipment life.
