Description

Technical Field

[0001] This utility model relates to the field of compressors, and in particular to a compressor lubricating oil recovery and consumption reduction device. Background Technology

[0002] Compressors are essential key equipment in chemical production. During operation, the rotating shaft of a compressor requires lubricating oil, which serves two purposes: lubrication and cooling, thus protecting the main operating components and extending their service life. During production, because the compressor operates at high speed, continuous friction between rotating and stationary parts causes localized high temperatures, leading to the instantaneous vaporization of the lubricating oil, producing oil vapor. This results in excessively high local pressure, affecting the compressor's normal operation. The discharge of compressor lubricating oil vapor mainly occurs through two routes: one is direct discharge from the compressor bearing housing to the atmosphere, and the other is direct discharge from the top of the lubricating oil tank into the atmosphere. In this process, the oil vapor is discharged along with the compressor's sealing and isolation gases. After natural condensation, the oil droplets fall to the ground, causing environmental pollution and wasting lubricating oil, while also increasing the labor intensity for employees cleaning the oil stains on the ground.

[0003] Currently, compressor lubricating oil vapor emissions mainly occur through two pathways. One is direct discharge from the compressor bearing housing into the atmosphere, or direct discharge from the top of the lubricating oil tank into the atmosphere. In this process, oil vapor is discharged along with the compressor's sealing and isolation gases. After natural condensation, the oil droplets fall to the ground, causing environmental pollution and wasting lubricating oil. It also increases the labor intensity of employees cleaning the oil stains on the ground. The other pathway is to recover the discharged oil vapor through packing or cooling methods, and then recycle the lubricating oil through a tower separator. This method not only increases the cost of equipment and operation methods, but also introduces other impurities into the liquefied lubricating oil, which must be further separated and purified before it can be reused. Therefore, we propose a compressor lubricating oil recovery and consumption reduction device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a compressor lubricating oil recovery and consumption reduction device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A compressor lubricating oil recovery and consumption reduction device includes a compressor body, an mounting plate connected to the bottom surface of the compressor body, mounting blocks connected to the front and back surfaces of the mounting plate, a groove formed on the bottom surface of the mounting plate, a rubber gasket connected to the inner wall of the groove, an oil conveying component connected to the left side of the compressor body, and a condensate return component connected to the upper surface of the compressor body.

[0007] In a further embodiment, the oil supply component includes a low-level oil tank connected to the compressor body, an oil pump connected to the left side of the compressor body, and a high-level oil tank connected to the upper surface of the compressor body.

[0008] In a further embodiment, a low-level oil pipe is connected to the left side of the compressor body, and the end of the low-level oil pipe away from the compressor body is connected to a low-level oil tank. An oil delivery pipe is connected to the input end of the oil delivery pump, and the end of the oil delivery pipe away from the oil delivery pump is connected to the low-level oil tank.

[0009] In a further embodiment, the output end of the oil pump is connected to a high-pressure oil pipe, and the end of the high-pressure oil pipe away from the oil pump is connected to a high-level oil tank.

[0010] In a further embodiment, the condensation reflux component includes an induced draft fan connected to the upper surface of the compressor body, the input end of the induced draft fan being connected to a guide pipe, and the end of the guide pipe away from the induced draft fan being connected to the compressor body.

[0011] In a further embodiment, the output end of the induced draft fan is connected to a liquefaction pipe, the outer surface of the liquefaction pipe is connected to a threaded condenser pipe, the end of the liquefaction pipe away from the induced draft fan is connected to a low-level oil tank, and the front of the compressor body is connected to a supplementary oil tank, which is connected to the liquefaction pipe through a conduit.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, through the coordinated operation of the induced draft fan and the condenser return component, efficiently draws the oil vapor generated by the compressor body into the liquefaction pipe. After being cooled and liquefied by demineralized water in the threaded condenser, it flows directly back to the low-level oil tank. Combined with the replenishment oil tank, it achieves stable replenishment, effectively reducing lubricating oil consumption, lowering enterprise operating costs, and improving resource utilization. At the same time, the lubricating oil in the low-level oil tank is transported to the high-level oil tank by the oil pump, forming a circulation system. Meanwhile, the low-temperature lubricating oil that condenses and returns mixes with the lubricating oil in the tank, lowering the overall oil temperature. This not only improves the lubricating performance of the lubricating oil but also effectively cools the compressor gears and other components, extending the service life of the equipment, reducing maintenance frequency and downtime, and ensuring production continuity.

After the oil and gas enter the liquefaction pipe 402, the externally wound threaded condenser pipe 403 is filled with demineralized water, and the oil and gas are cooled and liquefied through heat exchange.

[0021] The oil delivery component 6 includes a low-level oil tank 601 connected to the compressor body 2. An oil pump 604 is connected to the left side of the compressor body 2, and a high-level oil tank 606 is connected to the upper surface of the compressor body 2. The oil pump 604 stably delivers lubricating oil from the low-level oil tank 601 to the high-level oil tank 606 via an oil delivery pipe 602. A low-level oil pipe 603 is connected to the left side of the compressor body 2, with the end of the low-level oil pipe 603 furthest from the compressor body 2 connected to the low-level oil tank 601. The input end of the oil pump 604 is connected to... The oil delivery pipe 602 has one end away from the oil pump 604 connected to the low-level oil tank 601. The oil delivery pipe 602 connects the low-level oil tank 601 to the oil pump 604. The output end of the oil pump 604 is connected to a high-pressure oil pipe 605. The end of the high-pressure oil pipe 605 away from the oil pump 604 is connected to the high-level oil tank 606. The high-pressure oil pipe 605 can withstand the high pressure output by the oil pump 604, and stably and efficiently deliver lubricating oil from the low-level oil tank 601 to the high-level oil tank 606.

[0022] The condenser reflux unit 4 includes an induced draft fan 401 connected to the upper surface of the compressor body 2. The input end of the induced draft fan 401 is connected to a guide pipe 404. The end of the guide pipe 404 away from the induced draft fan 401 is connected to the compressor body 2. Through the induced draft fan 401, oil and gas can be quickly and efficiently drawn into the condenser reflux unit 4 via the guide pipe 404. The output end of the induced draft fan 401 is connected to a liquefaction pipe 402. A threaded condenser pipe 403 is connected to the outer surface of the liquefaction pipe 402. The end of the liquefaction pipe 402 away from the induced draft fan 401 is connected to a low-level oil tank 601. A supplementary oil tank 8 is connected to the front of the compressor body 2. The supplementary oil tank 8 is connected to the liquefaction pipe 402 via a conduit. Through the supplementary oil tank 8, it can serve as an auxiliary replenishment source to replenish lubricating oil to the system in a timely manner.

[0023] The working principle of this utility model is as follows:

[0024] During operation, the oil and gas generated by the compressor body 2 are drawn into the condenser return component 4 through the duct pipe 404 by the suction of the induced draft fan 401. After entering the liquefaction pipe 402, the externally wound threaded condenser pipe 403 is circulated with demineralized water as a cooling medium. Through heat exchange, the oil and gas are cooled and liquefied. Part of the liquefied lubricating oil flows directly back to the low-level oil tank 601, while the other part, with the assistance of the replenishment oil tank 8, ensures a stable supply of lubricating oil, realizing oil and gas recovery and reuse, and reducing lubricating oil loss. The lubricating oil in the low-level oil tank 601 is transported to the high-level oil tank 606 through the oil pipe 602 by the oil pump 604. The high-level oil tank 606 uses gravity to allow the lubricating oil to flow by gravity through the pipe into the compressor body 2 to lubricate the gears and other components. The lubricating oil after lubrication flows back to the low-level oil tank 601 due to gravity, forming a cycle. The low-temperature lubricating oil that has been condensed and returned enters the high-level oil tank 606, mixes with the lubricating oil in the tank, reduces the overall oil temperature, improves the lubrication effect, and extends the service life of the equipment.
