[0002] During the operation of the hydro-turbine generator set, the thrust, upper guide, and lower guide bearings rub against the sliding rotor at high speed, causing the temperature of the cooling lubricating oil to rise. During the high-speed rotation and stirring process, the lubricating oil in the oil tank hits the equipment in the oil tank to produce a large amount of high-temperature and high-pressure oil mist, which needs to be discharged in time. The oil mist is not only harmful to the human body, but if it is directly discharged into the air, it will be cooled and liquefied into oil droplets and spread in the equipment and factory buildings, which will increase the maintenance cost and cause troubles to the operation of the equipment. Therefore, oil mist respirators are usually used to collect and filter the high-pressure oil mist before discharging it. For oil mist respirators, in order to achieve better filtering effects, the filter element needs to be cleaned and replaced frequently.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1

[0028] Reference Figure 1 to Figure 4 , which is the first embodiment of the utility model, and provides an oil mist respirator, comprising an oil mist respirator unit 100, comprising a mist suction cylinder 101, and a respirator cover 102 arranged at the upper end of the mist suction cylinder 101, and the respirator cover 102 is sleeved on the upper end of the mist suction cylinder 101;

[0029] The condensation collection unit 200 includes an oil shield 201 connected to the respirator cover 102 and arranged outside the mist suction cylinder 101, an oil receiving pan 202 arranged at the lower end of the oil shield 201, and an oil drain valve 203 matched with the oil receiving pan 202.

[0030] Furthermore, the lower end of the mist suction cylinder 101 is a fixed plate 101a, on which a plurality of fixing holes 101a-1 are evenly provided for connecting and fixing the device to the front equipment. A left baffle plate 101b and a right baffle plate 101c are also provided inside the mist suction cylinder 101. There are a plurality of the left baffle plates 101b and the right baffle plates 101c arranged alternately along the height direction of the mist suction cylinder 101. It should be noted that the left baffle plate 101b and the right baffle plate 101c are arranged alternately to form an S-shaped oil mist channel, thereby increasing the heat dissipation area, so that a portion of the oil mist can be cooled and liquefied in the S-shaped oil mist channel and reflux to the interior of the front device.

[0031] Furthermore, the respirator cover 102 is an inverted bowl-shaped structure, and its inner diameter is consistent with the outer diameter of the mist suction cylinder 101. It should be noted that a positioning groove is vertically provided on the outer wall of the upper end of the mist suction cylinder 101, and a positioning key is provided on the inner wall of the respirator cover 102. The two cooperate to determine the direction of the respirator cover 102 so that it can close the upper end of the mist suction cylinder 101. A plurality of breathing holes 102a are evenly opened on the respirator cover 102, and the oil mist that has not been liquefied and refluxed enters the post-installation device through the breathing holes 102a for cooling and filtration.

[0032] Furthermore, a connecting shaft 102b is connected to the center position of the upper end of the respirator cover 102, and its upper end is a threaded connection section 102b-1, which is connected and cooperated with the oil shield 201 so that the oil shield can be fixedly connected thereto, and the oil shield has a certain height, so that the high-pressure oil mist has sufficient space for pressure reduction and filtration, which helps its liquefaction, reflux and collection.

[0033] Furthermore, a connecting hole 201a is opened at the center position of the upper end of the oil shield 201, which is connected to the connecting shaft 102b. An inner shrink ring 201b is also provided at the lower end of the oil shield 201, whose outer diameter is consistent with the inner diameter of the oil shield 201 and cooperates with the oil receiving pan 202.

[0034] Furthermore, an oil mist filter cartridge 201c is provided at the upper end of the oil shield 201, which is an annular baffle, and the lower end thereof is in contact with the respirator cover 102, so that an oil mist pressure relief space is formed between it and the respirator cover 102, thereby reducing the oil mist pressure and making the oil mist fully distributed for easy filtration, and its outer diameter is consistent with the outer diameter of the respirator cover 102, and a plurality of first filter holes 201c-1 are evenly arranged vertically and circumferentially on the side wall of the oil mist filter cartridge 201c for filtering the oil mist and performing preliminary filtration on the oil and gas molecules in the high-pressure oil mist so that they can flow back to the front device through the breathing hole 102a.

[0035] Furthermore, a plurality of deflector baffles 201d are horizontally arranged inside the oil shield 201, one side of which is fixed to the inner wall of the oil shield 201, and the other side is in conflict with the inner wall of the oil receiving pan 202. A plurality of second filter holes 201d-1 are evenly arranged on the deflector baffle 201d, which can perform multi-stage sufficient filtration and purification on the initially filtered oil mist, liquefy the oil and gas molecules and separate them from the air to a level that can be directly discharged.

[0036] Furthermore, the oil receiving pan 202 is sleeved on the outside of the mist suction cylinder 101, and the side in contact with the mist suction cylinder 101 is an inner sleeve 202a, whose lower end abuts against the mist suction cylinder 101 and the upper end abuts against the respirator cover 102, thereby shielding the side wall of the mist suction cylinder 101 and preventing the liquefied oil and gas molecules from flowing out of the device through the side wall of the mist suction cylinder 101 and causing pollution. The outside of the oil receiving pan 202 is an oil blocking cylinder 202b, which cooperates with the inner shrink ring 201b, and the distance between its inner wall and the outer wall of the inner shrink ring 201b is three millimeters, forming an air channel, so that the purified air can be discharged smoothly, and the filtered liquefied oil and gas can be collected in the oil receiving pan 202.

[0037] During use, during the operation of the front device, the high-pressure oil mist gas generated enters the mist suction cylinder 101 under pressure, and after preliminary cooling, liquefaction and reflux by the mist suction cylinder 101, it is filtered and purified multiple times by the oil shielding cover 201 to collect and discharge the oil and gas and air respectively. When the filtering effect is reduced due to the adhesion and accumulation of oil and gas in the device after high-intensity use, the front device is temporarily closed, the connection between the respirator cover 102 and the oil shielding cover 201 is loosened, the oil shielding cover 201 is pulled up to take out, clean it, and replace the oil mist filter cartridge 201c and the deflector baffle 201d. At the same time, the respirator cover 102 can be taken out and cleaned, and then the cleaned respirator cover 102 is installed, and then the oil shielding cover 201 is installed and fixed. The cleaning work is completed, and the respirator cover 102 and the oil shielding cover 201 can also be directly replaced to shorten the maintenance time.

[0038] In summary, the oil mist in the front device can be absorbed and preliminarily filtered and refluxed through the oil mist breathing unit 100, and the remaining oil mist can be filtered and collected and discharged separately through the condensation collection unit 200. The condensation collection unit 200 adopts a separate design, which can be easily disassembled and replaced, easy to clean, and better suitable for high-intensity oil mist filtration work.

[0039] Example 2

Based on the previous embodiment, this embodiment provides an oil mist respirator, which is different from the previous embodiment in that an oil collecting pan 202c is obliquely arranged inside the oil receiving pan 202, which can collect liquefied oil and gas and converge them to the lowest point along its inclined direction, and an oil outlet hole 202b-1 is also provided at the lower end of the oil retaining cylinder 202b. The oil outlet hole 202b-1 is opened at the lowest position of the oil collecting pan 202c, which is convenient for discharging the collected liquefied oil and gas.

[0041] Furthermore, the oil drain valve 203 is arranged at the oil outlet hole 202b-1, and the oil drain valve 203 can be opened at intervals to discharge the liquefied oil and gas in the oil collecting pan 202c, and can be reused.
