Description

TECHNICAL FIELD

[0001] The utility model relates to a chemical industry technical field, in particular to a compressor lubricating oil's oil fume treatment device. BACKGROUND

[0002] With the scale of coal chemical industry, petroleum chemical industry field device, centrifugal compressor is more and more common.But the lubricating oil produced in the operation process of compressor, oil fume not only causes the waste of resources, but also exists the environmental pollution problem.Although the engineering technical personnel has made the corresponding improvement in this respect, such as setting up oil mist separator in the top of oil tank, and good effect is obtained indeed.But it cannot treat all the oil fume produced in the operation process of compressor, such as the oil fume pipe on the top of compressor bearing box can also discharge a large amount of oil fume, and if it cannot be properly handled, it can also cause environmental pollution and resource waste. INNOVATION CONTENT

[0003] The utility model discloses a compressor lubricating oil's oil fume treatment device, and the compressor bearing box top oil fume pipe and lubricating oil station oil tank upper gas phase space are communicated, utilize the inside micro negative pressure of oil tank, and the oil fume produced at the bearing is absorbed to the inside of oil tank, and finally through oil fume fan and oil mist separator further processing, reach the purpose of saving oil product and avoiding the environmental pollution of operation site.

[0004] The utility model is realized through the following technical schemes:

[0005] A kind of compressor lubricating oil's oil fume treatment device, including compressor, the centrifugal compressor both ends bearing box top and atmosphere communicated oil fume pipe and lubricating oil station oil tank top gas phase space are communicated, simultaneously, original oil fume outlet is plugged, so it can handle the oil fume that is originally discharged into the atmosphere around compressor;

[0006] The micro negative pressure of oil tank can ensure that the oil fume produced at the bearing is smoothly discharged to the oil tank, and ensure that the bearing lubrication effect is good;

[0007] Oil fume discharged into the oil tank is further separated and recovered by oil mist separator, and then discharged to outdoor high point under the action of oil fume fan, reducing the pollution to working environment;

[0008] To facilitate observation whether the oil fume produced by bearing box can be smoothly discharged, we add a section of transparent steel wire hose to each branch pipe, and the oil fume can be clearly seen during operation.

[0009] As a further improvement to the above scheme, the lubricating oil station oil tank is provided with a valve, and the steel main pipe is connected to the oil tank through the valve.

[0010] As a further improvement of the above-mentioned scheme, the soft branch pipe adopts a 600mm long steel wire soft pipe.

[0011] As a further improvement of the above-mentioned scheme, the steel main pipe adopts a DN50 stainless steel pipe.

[0012] Compared with the prior art, the present application has the following advantages: simple scheme, energy saving and environmental protection. BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 1 The present application is a process flow diagram. DETAILED DESCRIPTION

[0014] The present application will be further described below with reference to the accompanying drawings.

[0015] As shown in the drawings, Figure 1 A compressor lubricating oil fume treatment device, comprising a compressor, the compressor is provided with a high-pressure cylinder 1 and a low-pressure cylinder 2, the two ends of the high-pressure cylinder 1 and the low-pressure cylinder 2 are respectively provided with a pipe 3, a pipe 4 and a pipe 5, a pipe 6 for discharging fume, each pipe is connected with a soft branch pipe 7 at one end, the other end of the soft branch pipe 7 is connected to a steel main pipe 8, and the steel main pipe 8 is connected to a lubricating oil station oil tank 9.

[0016] The micro-negative pressure of the oil tank 9 can ensure that the fume generated at the bearing is smoothly discharged to the oil tank 9, and the bearing lubrication effect is good;

[0017] The fume discharged into the oil tank 9 is further separated and recovered by an oil mist separator, and then discharged to an outdoor high point under the action of an oil fume exhaust fan, thereby reducing the pollution to the working environment;

[0018] In order to observe whether the fume generated by the bearing box can be smoothly discharged, a transparent steel wire soft pipe is additionally arranged on each soft branch pipe 7, and the fume passing through can be clearly seen during operation.

[0019] As a further improvement of the above-mentioned scheme, the lubricating oil station oil tank 9 is provided with a valve 10, and the steel main pipe 8 is connected to the oil tank 9 through the valve 10.

[0020] As a further improvement of the above-mentioned scheme, the soft branch pipe 7 adopts a 600mm long steel wire soft pipe.

[0021] The working principle of the oil fume treatment device of the compressor lubricating oil is as follows: the exhaust pipe on the top of each bearing box of the compressor is removed, a hole is opened about 100mm below the exhaust port, a DN25 stainless steel short pipe with a length of 500mm is welded to each hole, then a steel wire flexible pipe with a length of about 600mm is connected to each short pipe by a buckle, the other end of the flexible pipe is also connected to a DN25 stainless steel pipe by a buckle, the above branch pipes are extended to the base platform of the compressor, are gathered to a DN50 stainless steel main pipe, and then are connected to the valve of the standby interface on the upper part of the oil tank of the lubricating oil station; when the pipes are connected, the main pipe is ensured to have a proper inclination to the standby interface of the oil tank, so that the condensed oil drops can smoothly flow into the oil tank; after the pipe connection is completed, the impurities in the pipes are blown clean by the factory air, the connection parts are firmly connected; finally, the original exhaust port on the upper part of the bearing box of the compressor is tightly sealed.

[0022] As a further improvement of the above solution, the steel main pipe 8 is a DN50 stainless steel pipe.

[0023] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
