Description

Technical Field

[0001] This invention relates to the field of industrial production technology, specifically to an air compressor air-side auxiliary cooling system based on condensate self-circulation evaporation heat exchange. Background Technology

[0002] In industrial production, air-cooled screw air compressors are commonly used fluid machinery and are widely applied in various manufacturing and processing scenarios. However, they face two major challenges when operating in high-temperature and high-humidity environments during the summer: Firstly, when the ambient temperature exceeds 35°C, the air heat exchange efficiency decreases significantly, causing the air compressor oil temperature to remain at a high level above 95°C for extended periods. This not only easily triggers high-temperature shutdown protection but also causes problems such as shortened lubricating oil life and deterioration of compressor isothermal efficiency, seriously affecting production continuity and equipment operating efficiency. Secondly, during the air compressor compression process, a large amount of acidic condensate containing trace amounts of oil is released. Direct discharge of this condensate violates environmental regulations, and traditional treatment methods require the installation of dedicated collection pipelines or oil-water separation equipment, which has drawbacks such as high investment costs and cumbersome disposal procedures.

[0003] Among the existing improvement solutions for air compressor heat dissipation, water-cooling retrofit requires large-scale engineering construction, which is not only costly but also relies on external water supply, has poor adaptability, and is difficult to meet the universal needs of different scenarios. Conventional air-cooling auxiliary solutions do not take into account the needs of condensate treatment and fail to achieve synergy between heat treatment and waste treatment, resulting in both resource waste and environmental pressure.

[0004] Therefore, there is an urgent need for a technical solution that does not require an external water source, is easy to install, and can simultaneously solve the problems of heat dissipation bottleneck and condensate disposal. Summary of the Invention

[0005] To solve the above technical problems, an air compressor air-side auxiliary cooling system based on condensate self-circulation evaporation heat exchange is provided. This technical solution solves the above problems.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An auxiliary cooling system for the air side of an air compressor based on condensate self-circulation evaporation heat exchange includes: Condensate closed-loop collection module, intelligent atomizing heat exchange module, thermal variable frequency control module, non-intrusive installation module; The closed-loop condensate collection module is used to receive oily acidic condensate discharged from the air compressor air-water separator and the refrigerated dryer. After multi-stage sedimentation and filtration, impurities and floating oil are removed to form a clean cooling working fluid, which is then collected, purified and reused in a cycle. The intelligent atomizing heat exchange module is electrically connected to the condensate closed-loop collection module, which pressurizes the clean cooling medium and converts it into micron-level water mist of 10-50μm. The water mist is then sprayed into the airflow through a nozzle group arranged upstream of the radiator airflow field. The thermal variable frequency control module is electrically connected to the intelligent atomizing heat exchange module. It monitors the temperature of the air compressor oil pipe in real time through a temperature sensor, switches between standby mode and intervention mode, and performs adaptive adjustment of spray start / stop and spray intensity. The non-invasive installation module uses flexible connectors and snap-fit ​​structures to attach the nozzle assembly, pipelines, and liquid storage unit of the intelligent atomizing heat exchange module to the outside of the original heat dissipation and protection net of the air compressor, thus completing the assembly operation.

[0007] Preferably, the condensate closed-loop collection module includes: The liquid storage and sedimentation unit uses a buffer liquid storage tank made of high-density polyethylene. A primary filter screen and a floating oil isolation plate are installed inside the tank. It automatically receives condensate through liquid level difference and performs the sedimentation of large particles and separation of floating oil. The working fluid purification unit is equipped with a precision filter element at the outlet of the liquid storage and sedimentation unit to perform secondary purification of the condensate, removing tiny oil droplets and suspended impurities. The self-priming delivery unit is equipped with a corrosion-resistant miniature diaphragm pump. Utilizing the pump's self-priming function and pressure regulation characteristics, it pressurizes and delivers the purified condensate to the intelligent atomizing heat exchange module.

[0008] Preferably, the intelligent atomizing heat exchange module includes: The high-pressure booster unit is connected to the self-priming conveying unit and uses a mini high-pressure pump to increase the pressure of the condensate to a preset threshold. The nozzle array unit consists of multiple quick-connect brass / stainless steel micro-mist nozzles arranged in a matrix according to the size of the radiator air inlet, so that the nozzle atomization angle is adapted to the airflow direction. The flow field adaptation unit adjusts the nozzle's installation height and spray angle based on the negative pressure flow field characteristics of the air compressor cooling fan, allowing water mist to enter the gap between the heat dissipation fins with the airflow.

[0009] Preferably, the thermal frequency converter control module includes: The temperature sensing unit uses a magnetic temperature sensor that is attached to the surface of the oil return pipe of the oil-gas separator to collect the air compressor exhaust temperature data in real time and perform data sampling at a preset frequency. The mode switching unit has a preset temperature threshold. When the monitored temperature is below the threshold, the control system switches to standby mode and only activates the condensate collection function. When the monitored temperature is above or equal to the threshold, the control system activates the intervention mode and controls the intelligent atomizing heat exchange module to perform intermittent and continuous spraying operations. The variable frequency control unit calculates the difference between the real-time temperature and the preset threshold, and dynamically adjusts the output power and spray frequency of the micro high-pressure pump based on the difference.

[0010] Preferably, the non-invasive installation module includes: The flexible connection unit uses a corrosion-resistant high-pressure hose to connect the self-priming delivery unit, the high-pressure boosting unit, and the nozzle array unit. The quick-release fixing unit uses a snap-on bracket and an adsorption base to fix the nozzle array unit to the outside of the radiator protective net and the liquid storage sedimentation unit to the side of the air compressor base. The sealed protection unit is equipped with corrosion-resistant seals at the pipe interfaces and a dustproof and breathable cover is installed on the top of the liquid storage and sedimentation unit.

[0011] Preferably, the system performs load-water source balance operation: under high temperature and high humidity conditions, the condensate output is matched with the auxiliary heat dissipation demand through the liquid storage buffer operation of the condensate closed-loop collection module and the spray adjustment operation of the intelligent atomization heat exchange module, and no external water source replenishment operation is performed.

[0012] Preferably, the intelligent atomizing heat exchange module performs spray intensity adjustment operation: it collects real-time temperature through the temperature sensing unit, calculates the difference between the real-time temperature and the preset threshold, establishes a positive correlation between spray intensity and temperature difference, and increases the spray intensity by 20%-30% for every 5℃ increase in temperature difference, until the maximum spray volume is reached.

[0013] Preferably, it also includes a zero-emission closed-loop unit, which atomizes all the condensate through an intelligent atomization heat exchange module, so that the atomized condensate evaporates into the atmosphere.

[0014] Preferably, the condensate closed-loop collection module further includes a liquid level monitoring unit, which monitors the liquid level of the storage and sedimentation unit in real time. When the liquid level is lower than the minimum threshold, a low liquid level warning is triggered and the spraying operation is suspended; when the liquid level is higher than the maximum threshold, an overflow protection operation is initiated.

[0015] Preferably, the nozzle array unit performs a nozzle angle calibration operation: according to the arrangement direction of the radiator fins and the flow trajectory of the airflow, the spray angle of each nozzle is adjusted one by one so that the water mist coverage area completely overlaps with the airflow area of ​​the radiator fins.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention constructs a closed-loop chain for condensate collection, purification, atomization, and evaporation, directly utilizing the oily acidic condensate discharged from the air compressor itself as the cooling medium. No additional cooling water source is required. This not only realizes the resource utilization of waste condensate but also avoids the environmental risks of direct discharge of condensate, achieving the environmental effect of zero discharge and zero treatment cost.

[0017] 2. Employing 10-50μm micron-level atomization technology, the latent heat of vaporization of water is used to significantly reduce the radiator inlet air temperature, greatly improve heat exchange efficiency, effectively control the air compressor oil temperature within a safe threshold, avoid high-temperature shutdown, ensure production continuity, extend the service life of lubricating oil, and improve the isothermal efficiency of the compressor.

[0018] 3. The system has load and water source balance characteristics. Under high temperature and high humidity conditions, the condensate output increases synchronously with the water content of the air compressor exhaust. Through liquid storage buffer and spray regulation, the heat dissipation demand is dynamically matched. Supply and demand balance can be achieved without manual intervention, and it can adapt to different environmental conditions.

[0019] 4. Based on the non-intrusive installation design, assembly is completed through flexible connectors and snap-fit ​​structures. There is no need to perform destructive modifications such as drilling and welding on the air compressor body. It is easy to install and flexible to disassemble. It is compatible with various air-cooled screw air compressors, has strong universality, and reduces the threshold for modification and the risk of equipment damage.

[0020] 5. Based on the thermal variable frequency control logic, the operating mode is dynamically switched by real-time monitoring of oil temperature, and the spray start / stop and intensity are precisely adjusted to avoid energy waste, achieve the optimal match between heat dissipation demand and energy consumption, and further improve the economic efficiency of system operation.

[0022] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figure 1 As shown, an air compressor air-side auxiliary cooling system based on condensate self-circulation evaporation heat exchange includes: a condensate closed-loop collection module, an intelligent atomization heat exchange module, a thermal variable frequency control module, and a non-intrusive installation module; The closed-loop condensate collection module is used to receive oily acidic condensate discharged from the air compressor air-water separator and the refrigerated dryer. After multi-stage sedimentation and filtration, impurities and floating oil are removed to form a clean cooling working fluid, which is then collected, purified and reused in a cycle. The intelligent atomizing heat exchange module is connected to the condensate closed-loop collection module to pressurize the clean cooling medium and convert it into micron-level water mist of 10-50μm. The water mist is then sprayed into the airflow through a nozzle group arranged upstream of the radiator airflow field. The thermal frequency conversion control module establishes an electrical connection with the intelligent atomizing heat exchange module, monitors the air compressor oil pipe temperature in real time through a temperature sensor, switches between standby mode and intervention mode, and performs adaptive adjustment operations for spray start / stop and spray intensity. The non-invasive installation module uses flexible connectors and snap-fit ​​structures to attach the nozzle assembly, pipelines, and liquid storage unit of the intelligent atomizing heat exchange module to the outside of the original heat dissipation and protection net of the air compressor, thus completing the assembly operation.

[0024] In some embodiments, the multi-stage sedimentation and filtration operation specifically comprises three stages: primary gravity sedimentation, oil separation, and precision filtration; the pressure range for pressurization is set to 1.2-2.0 MPa to ensure that the water mist particle size remains stable at 10-50 μm; the temperature threshold for switching between standby mode and intervention mode is preset to 88℃; the spray intensity adjustment is performed according to the correspondence between temperature difference and intensity gradient, with the intensity increasing by 20%-30% for every 5℃ increase in the temperature difference; before assembly, the dust on the surface of the heat dissipation protective mesh must be cleaned, and the flexible connectors must be arranged to fit snugly along the contour of the air compressor body to avoid obstructing the air duct.

[0025] In some embodiments, the condensate closed-loop collection module includes: The liquid storage and sedimentation unit uses a buffer liquid storage tank made of high-density polyethylene. A primary filter screen and a floating oil isolation plate are installed inside the tank. It automatically receives condensate through liquid level difference and performs the sedimentation of large particles and separation of floating oil. The working fluid purification unit is equipped with a precision filter element at the outlet of the liquid storage and sedimentation unit to perform secondary purification of the condensate, removing tiny oil droplets and suspended impurities. The self-priming delivery unit is equipped with a corrosion-resistant miniature diaphragm pump. Utilizing the pump's self-priming function and pressure regulation characteristics, it pressurizes and delivers the purified condensate to the intelligent atomizing heat exchange module.

[0026] The buffer tank has a liquid level difference controlled at 5-10cm to ensure that condensate flows in automatically without overflowing; the primary filter screen has a pore size of 100-150μm, the oil float isolation plate is installed at a height of 1 / 3 of the tank height from the bottom, and the oil floats are discharged through the top overflow port; the precision filter element has a filtration accuracy of less than 5μm and needs to be replaced every 30 days; the micro diaphragm pump has a self-priming height of ≤1m, a pressure adjustment range of 0.3-0.8MPa, and a delivery flow rate matched to the spraying requirements, set at 3-8L / h.

[0027] In some embodiments, the intelligent atomizing heat exchange module includes: The high-pressure booster unit is connected to the self-priming conveying unit and uses a mini high-pressure pump to increase the pressure of the condensate to a preset threshold. The nozzle array unit consists of multiple quick-connect brass / stainless steel micro-mist nozzles arranged in a matrix according to the size of the radiator air inlet, so that the nozzle atomization angle is adapted to the airflow direction. The flow field adaptation unit adjusts the nozzle's installation height and spray angle based on the negative pressure flow field characteristics of the air compressor cooling fan, allowing water mist to enter the gap between the heat dissipation fins with the airflow.

[0028] The micro high-pressure pump has a preset pressure threshold of 1.2-2.0 MPa, which is precisely matched with the atomization requirements of the nozzles. The nozzle array spacing is 5-8 cm to ensure that there are no blind spots in the water mist coverage. The atomization angle of the brass / stainless steel nozzles is preset to 30-45°. When adapting the flow field, the airflow velocity (target range 3-5 m / s) is first detected by an anemometer. Then, the nozzle installation height is adjusted to 10-15 cm from the protective net, and the spray angle is tilted downwards by 5-10° along the airflow direction to ensure that the water mist enters the fin gap in the same direction as the airflow.

[0029] In some embodiments, the thermal frequency converter control module includes: The temperature sensing unit uses a magnetic temperature sensor that is attached to the surface of the oil return pipe of the oil-gas separator to collect the air compressor exhaust temperature data in real time and perform data sampling at a preset frequency. The mode switching unit has a preset temperature threshold. When the monitored temperature is below the threshold, the control system switches to standby mode and only activates the condensate collection function. When the monitored temperature is above or equal to the threshold, the control system activates the intervention mode and controls the intelligent atomizing heat exchange module to perform intermittent and continuous spraying operations. The variable frequency control unit calculates the difference between the real-time temperature and the preset threshold, and dynamically adjusts the output power and spray frequency of the micro high-pressure pump based on the difference.

[0030] The magnetic temperature sensor has a sampling frequency of 1 time / 30 seconds and a measurement accuracy of ±0.5℃. The temperature threshold is preset to 88℃ and can be adjusted within the range of 85-90℃ via the control panel. The intermittent spray cycle is 5-10 seconds of spraying followed by a 10-15 second pause. Continuous spraying is suitable for operating conditions with temperatures above 95℃. The power adjustment step of the frequency converter is 10%, and the spray frequency adjustment range is 5-20 times per minute. Maximum output power is activated when the difference is ≥10℃.

[0031] In some embodiments, the non-invasive installation module includes: The flexible connection unit uses a corrosion-resistant high-pressure hose to connect the self-priming delivery unit, the high-pressure boosting unit, and the nozzle array unit. The quick-release fixing unit uses a snap-on bracket and an adsorption base to fix the nozzle array unit to the outside of the radiator protective net and the liquid storage sedimentation unit to the side of the air compressor base. The sealed protection unit is equipped with corrosion-resistant seals at the pipe interfaces and a dustproof and breathable cover is installed on the top of the liquid storage and sedimentation unit.

[0032] Among them, the corrosion-resistant high-pressure hose has a pressure rating of ≥2.5MPa, an inner diameter of 8-12mm, and a bending radius of ≥5cm to avoid bending affecting water flow; the snap-on bracket is made of ABS material and is fixed to the edge of the protective net by expansion buckles; the adsorption base has an adsorption force of ≥50N to ensure a firm installation; the sealing parts are made of fluororubber material, which is suitable for acidic condensate water environments; the dustproof and ventilated cover has a built-in 50μm dustproof net, which takes into account both ventilation and prevention of impurities from entering.

[0033] In some embodiments, the system performs load-water source balance operation: under high temperature and high humidity conditions, the condensate output is matched with the auxiliary heat dissipation demand through the liquid storage buffer operation of the condensate closed-loop collection module and the spray adjustment operation of the intelligent atomizing heat exchange module, and no external water source replenishment operation is performed.

[0034] In the liquid storage and buffering operation, the capacity of the buffer liquid storage tank is designed according to the maximum condensate output of the air compressor in 2 hours to ensure no overflow during peak output; the response time of the spray adjustment operation is ≤30 seconds. When the condensate output increases by 10%, the spray intensity increases by 10%-15% simultaneously. The condensate output is fed back in real time through the flow sensor, and the spray parameters are dynamically adjusted.

[0035] In some embodiments, the intelligent atomizing heat exchange module performs a spray intensity adjustment operation: it collects real-time temperature through a temperature sensing unit, calculates the difference between the real-time temperature and a preset threshold, establishes a positive correlation between spray intensity and temperature difference, and increases the spray intensity by 20%-30% for every 5°C increase in temperature difference until the maximum spray volume is reached.

[0036] The spray intensity is quantified by the amount of spray per unit time, with the initial spray intensity set at 3-5 L / h. The specific formula for the positive correlation mapping relationship is: the current spray intensity is the initial intensity × (1 + 0.04 × temperature difference) (20% corresponds to a coefficient of 0.04). The maximum spray volume is calculated based on the air inlet area of ​​the radiator and is set at 5-8 L / (h·m²) to avoid excessive water mist causing condensation on the fins.

[0037] In some embodiments, a zero-emission closed-loop unit is also included, which atomizes all the condensate through an intelligent atomization heat exchange module, so that the atomized condensate evaporates into the atmosphere.

[0038] The atomization process must ensure that the condensed water is completely converted into 10-50μm water mist without any liquid water droplets remaining. The evaporation process relies on the airflow (speed ≥3m / s) generated by the air compressor cooling fan, so that the water mist evaporates before flowing through the radiator fins. The humidity at the air outlet is monitored by a humidity sensor to ensure that the evaporation rate is ≥98% and there is no secondary pollution caused by liquid water droplets.

[0039] In some embodiments, the condensate closed-loop collection module further includes a liquid level monitoring unit, which monitors the liquid level of the storage and sedimentation unit in real time. When the liquid level is lower than the minimum threshold, a low liquid level warning is triggered and the spraying operation is suspended; when the liquid level is higher than the maximum threshold, an overflow protection operation is initiated.

[0040] The liquid level monitoring unit uses a float-type liquid level sensor, with the lowest liquid level threshold set at 10% of the storage tank capacity and the highest liquid level threshold set at 80%. Low liquid level warning is achieved through an audible and visual alarm with an alarm volume ≥80dB. After the spraying is stopped, the condensate supply needs to be manually checked. The overflow protection operation guides excess condensate to a spare container through the overflow pipe on the top of the storage tank to avoid direct discharge. The spare container needs to be emptied and disposed of regularly.

[0041] In some embodiments, the nozzle array unit performs a nozzle angle calibration operation: according to the arrangement direction of the radiator fins and the flow trajectory of the airflow, the spray angle of each nozzle is adjusted one by one so that the water mist coverage area completely overlaps with the airflow area of ​​the radiator fins.

[0042] The angle calibration uses a laser angle meter with a calibration accuracy of ±1°. First, the fin arrangement direction of the radiator is photographed by a high-definition camera to determine the fin extension angle. Then, the nozzle spray angle is adjusted to be parallel to the fin direction. After calibration, the water mist coverage is tested by a smoke generator to ensure that no fin areas are missed. The coverage of each nozzle overlaps with the adjacent nozzle by 10%-15% to avoid blind spots.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
