Description

Technical Field

[0001] This utility model relates to the field of oil mist separation technology, and more specifically, to a high-efficiency oil mist separator. Background Technology

[0002] Oil mist generation is a widespread problem in modern industrial production. Whether in machining, metal heat treatment, chemical production, or other industrial fields, various processes such as cutting, grinding, quenching, and spraying generate large amounts of oil mist. This oil mist not only pollutes the working environment and affects the health of operators, but it can also corrode and damage production equipment, reducing its lifespan and performance.

[0003] Oil mist separators, as effective oil mist treatment equipment, are widely used in various industrial scenarios. Their main function is to separate oil mist particles from the air, ensuring that exhaust air meets environmental standards, while also recovering the oil from the mist for resource reuse. However, traditional oil mist separators face some problems in practical use, one of the most prominent being the rapid aging of the filter media due to excessively high oil mist temperatures.

[0004] In many industrial production processes, oil mist often reaches high temperatures, especially oil mist generated by some high-temperature processes, where temperatures can reach 80°C or even higher. When this high-temperature oil mist directly enters the oil mist separator, it comes into direct contact with the filter media. Under high-temperature conditions, the physical and chemical properties of the filter media undergo significant changes, such as damage to the fiber structure and reduction in porosity, leading to a substantial decrease in filtration efficiency and a shortened lifespan. Frequent replacement of filter media not only increases production costs but also affects the continuity and stability of production.

[0005] To address the impact of high-temperature oil mist on filter media, some traditional oil mist separators employ simple air-cooling or water-cooling methods to cool the incoming oil mist. Air-cooling typically involves using an external fan to carry away heat through airflow. However, this method has limited cooling effectiveness, especially in high-temperature environments where the air itself is also quite warm, making it difficult to reduce the oil mist temperature to an ideal level. Furthermore, air-cooling is significantly affected by ambient temperature and airflow speed, resulting in poor stability.

[0006] Therefore, this application provides a high-efficiency oil mist separator to solve the problems mentioned in the background art. Utility Model Content

[0007] 1. Technical problems to be solved

[0008] To address the problems existing in the prior art, the purpose of this utility model is to provide a high-efficiency oil mist separator that can cool down the oil mist entering the air inlet pipe, making the filter material less prone to rapid aging, thereby improving the service life of the oil mist separator.

[0009] 2. Technical Solution

[0010] To solve the above problems, the present invention adopts the following technical solution.

[0011] A high-efficiency oil mist separator includes an oil mist separator body, an air inlet pipe fixedly connected to the outer end of the oil mist separator body, a connecting pipe fixedly connected to the outer end of the air inlet pipe, a storage tank fixedly connected to the upper end of the oil mist separator body, a circulation pump fixedly connected to the outer end of the storage tank, a heat exchange pipe connected to the outer end of the circulation pump, and multiple evenly distributed through holes drilled in the upper end of the connecting pipe. A heat-conducting rod is slidably connected in the through holes, and the heat-conducting rod is connected to the connecting pipe. This allows for cooling of the oil mist entering the air inlet pipe, preventing the filter material from aging rapidly and thus improving the service life of the oil mist separator.

[0012] As a further improvement of this utility model, the connecting pipe and the heat-conducting rod are both made of metal material with a thermal conductivity of ≥400W / (m·K).

[0013] As a further improvement of this utility model, the outer end of the heat-conducting rod is provided with a sealing layer, which is made of rubber material.

[0014] As a further improvement of this utility model, a limiting plate is fixedly connected to the bottom end of the heat-conducting rod, and the limiting plate is located inside the connecting pipe.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. This utility model's high-efficiency oil mist separator, through its unique structural design, achieves efficient cooling of oil mist entering through the air inlet pipe. In traditional oil mist separators, high-temperature oil mist directly contacts the filter media, easily leading to rapid aging of the filter media, reducing separation efficiency and service life. However, after the circulation pump is started, the coolant circulates in a closed loop formed by the storage tank, circulation pump, and heat exchange tube, cooling the connecting pipe. The heat from the high-temperature oil mist in the connecting pipe is quickly dissipated, reducing the temperature of the oil mist entering the main body of the oil mist separator. The filter media is no longer subjected to a high-temperature environment, thus preventing rapid aging and significantly improving the service life of the oil mist separator, while reducing equipment replacement costs and maintenance frequency.

[0018] 2. Both the connecting pipe and the heat-conducting rod are made of metal with a thermal conductivity of ≥400W / (m·K), which is 3-5 times higher than that of ordinary steel. This high thermal conductivity material can quickly dissipate the heat from the high-temperature oil mist (up to 80℃) in the connecting pipe. The heat-conducting rod is in full contact with the oil mist in the connecting pipe, quickly absorbs the heat, and transfers the heat out through its own thermal conductivity, which greatly improves the efficiency of heat dissipation and ensures that the oil mist is effectively cooled before entering the main body of the oil mist separator.

[0019] 3. The heat-conducting rod features an ingenious design. Its outer end is equipped with a sealing layer made of rubber material, which ensures the seal between the heat-conducting rod and the connecting pipe, preventing oil mist leakage, and reduces friction between the heat-conducting rod and the connecting pipe, allowing the heat-conducting rod to slide smoothly. The limiting plate fixedly connected to the bottom of the heat-conducting rod is located inside the connecting pipe, effectively limiting the range of movement of the heat-conducting rod and preventing it from detaching from the connecting pipe, thus ensuring the stability and reliability of the device. In addition, the high-temperature oil mist inside the connecting pipe causes the air in the heat-conducting rod and a specific structure (the original text lacks a component name, presumably a component that works with the heat-conducting rod to achieve heat transfer) to expand, driving the heat-conducting rod upward and bringing it closer to the heat exchange tube, thereby transferring heat to the heat exchange tube more efficiently, further improving the heat exchange efficiency of the heat exchange tube, and realizing the effective transfer and utilization of energy.

[0020] 4. The coolant circulates in a closed loop formed by the storage tank, circulating pump, and heat exchange tubes. This design not only ensures the continuous circulation of coolant, reducing coolant waste and lowering operating costs, but also avoids environmental pollution caused by coolant discharge, which is in line with the development concept of energy conservation and environmental protection. At the same time, the closed-loop system can stably provide cooling effect, ensuring that the oil mist separator maintains good cooling performance under different operating conditions.

[0029] Example:

[0030] Please see Figures 1-3 A high-efficiency oil mist separator includes an oil mist separator body 1, an air inlet pipe 2 fixedly connected to the outer end of the oil mist separator body 1, a connecting pipe 3 fixedly connected to the outer end of the air inlet pipe 2, a storage tank 4 fixedly connected to the upper end of the oil mist separator body 1, a circulation pump 5 fixedly connected to the outer end of the storage tank 4, a heat exchange pipe 6 connected to the outer end of the circulation pump 5, and multiple evenly distributed through holes 7 drilled at the upper end of the connecting pipe 3. A heat-conducting rod 8 is slidably connected in the through holes 7, and a 9 connects the heat-conducting rod 8 and the connecting pipe 3. This allows for cooling of the oil mist entering the air inlet pipe, making the filter material less prone to rapid aging, thereby improving the service life of the oil mist separator.

[0031] Please see Figures 1-3Both the connecting pipe 3 and the heat-conducting rod 8 are made of metal material with a thermal conductivity of ≥400W / (m·K), which is 3-5 times better than ordinary steel. It can quickly dissipate the heat of high-temperature oil mist in the connecting pipe, which can reach up to 80℃. The outer end of the heat-conducting rod 8 is provided with a sealing layer 801, which is made of rubber material. The bottom end of the heat-conducting rod 8 is fixedly connected to a limiting plate 802, which is located inside the connecting pipe 3.

[0032] Working principle: When using this device, the technician starts the circulation pump 5, which draws the coolant from the storage tank 4 and inputs it into the heat exchange tube 6. The coolant circulates in a closed loop formed by the storage tank 4, the circulation pump 5, and the heat exchange tube 6, thereby cooling the connecting pipe 3. The high-temperature oil mist in the connecting pipe 3 causes the air in the heat-conducting rods 8 and 9 to expand, moving the heat-conducting rods 8 upward. This brings the heat-conducting rods 8 closer to the heat exchange tube 6, transferring heat to the heat exchange tube 6 and improving its heat exchange efficiency. Compared with the prior art, this invention can cool the oil mist entering the air inlet pipe, making the filter material less prone to rapid aging and thus improving the service life of the oil mist separator.
