Description

Technical Field

[0001] The utility model relates to the field of petrochemical equipment, in particular to a cleaning device for an oil-gas-water three-phase separator. Background Technique

[0002] The oil-gas-water three-phase separator is an essential important separation device in the production equipment of the petrochemical field. The oil, gas, and water mixture liquid enters the three-phase separator. After passing through the rectifier, corrugated plate group, inclined plate group, etc., most of the liquid settles to the liquid phase area of the separation and sedimentation chamber. A very small part of the liquid continues to settle by the gravity of the liquid. After the remaining liquid is further separated by the demister, the gas enters the natural gas system through the pressure regulating valve. After the settled oil-water mixture stays for a period of time, it gradually stratifies due to the density difference. The water deposits at the bottom of the water collection tank and the liquid phase area. The upper part of the liquid phase area is the oil layer. When the liquid level of the oil layer is higher than the top of the oil separation plate, it slowly flows into the oil chamber and then is discharged from the oil outlet at the lower part of the oil chamber. The water in the liquid phase area settles and separates to the bottom layer of the sedimentation chamber and is discharged through the water outlet valve.

[0003] In this process, the oil-gas-water mixture entering the separator will inevitably be mixed with some impurities, sediment and other small particles. After the separator operates for a period of time, the sediment and impurities accumulate inside the tank body, which will affect the separation effect. Therefore, it is necessary to regularly clean the inner wall of the separator.

[0004] The traditional method generally sets a number of flushing holes on the longitudinally extending spray pipe, and sprays water flow through the flushing holes. The flushing range is small, the flushing effect is not good, the direction of the flushing water flow cannot be controlled, it is difficult to clean the complex structure inside the tank body, the flushing efficiency is low, and water resources are wasted. It is necessary for workers to enter the equipment manually to remove, the labor intensity of the operators is large, the production cost is high, and the shutdown removal time is increased.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A cleaning device for an oil-gas-water three-phase separator, including a fixed column. Electric telescopic rods are fixedly connected to both the left and right ends of the fixed column.

The thick sleeve is slidably sleeved on the outer wall of the thin sleeve. The outer walls of the thick sleeve and the thin sleeve are fixedly connected with a telescopic brush. A plurality of water outlet holes are opened in the inner walls of the thick sleeve and the thin sleeve.

[0007] In order to fix the device and drain sewage, as an optimization of the cleaning device for the oil-gas-water three-phase separator of the present utility model, on the opposite sides of the outer walls of the two second hydraulic telescopic rods, rubber scraping plates are fixedly connected.

On the outer walls of the two electric telescopic rods, two-way hydraulic telescopic rods are rotatably connected. At the upper and lower ends of each of the two two-way hydraulic telescopic rods, anti-slip pads are fixedly connected.

[0008] In order to drive the telescopic brush and the rubber scraping plate to rotate, as an optimization of the cleaning device for the oil-gas-water three-phase separator of the present utility model, a motor is installed on the side wall of the two-way hydraulic telescopic rod on the left side. The output end of the motor is fixedly connected with a first gear.

[0009] In order to fix the column and the electric telescopic rod to rotate, as an optimization of the cleaning device for the oil-gas-water three-phase separator of the present utility model, a second gear is fixedly connected to the outer wall of the electric telescopic rod on the left side. The first gear and the second gear are meshed and connected.

[0010] In order to supply water for cleaning and export the sewage, as an optimization of the cleaning device for the oil-gas-water three-phase separator of the present utility model, one end of the thick sleeve is communicated with a water supply pipe. The other end of the water supply pipe penetrates through the interiors of the first hydraulic telescopic rod and the electric telescopic rod on the left side and extends out from the left end of the electric telescopic rod on the left side. The side walls of the two water pumping trays are communicated with drain pipes. The other ends of the drain pipes penetrate through the interiors of the second hydraulic telescopic rod and the electric telescopic rod on the right side and extend out from the right end of the electric telescopic rod on the right side.

[0011] In order to prevent the pipes from knotting during the rotation process, as an optimization of the cleaning device for the oil-gas-water three-phase separator of the present utility model, one end of each of the water supply pipe and the drain pipe is fixedly connected with a first connecting ring. One end of each of the two first connecting rings is rotatably connected with a second connecting ring. The two second connecting rings are fixedly connected to the outer walls of the respective two-way hydraulic telescopic rods close to them.

[0012] In order to input the cleaning water under pressure and extract the waste water for cleaning, as an optimization of the cleaning device for the oil-gas-water three-phase separator of the present utility model, one end of the second connecting ring on the left side is fixedly connected with a pressure pump through a hose.

The motor is started to drive the first gear to rotate. During the rotation of the first gear, the second gear is driven to rotate, so that the two electric telescopic rods and the fixed column all rotate, thereby driving the two first hydraulic telescopic rods and the two second hydraulic telescopic rods to rotate around the axis of the three-phase separator, so that the telescopic brush and the rubber scraper both rotate around the axis of the three-phase separator. During the rotation, the telescopic brush and the rubber scraper are in close contact with the inner wall of the three-phase separator.

[0016] 2. In the present utility model, electric telescopic rods are fixedly connected to both ends of the fixed column, so that the length of any electric telescopic rod can be changed by the operation of the staff. When the lengths of the two electric telescopic rods change, the thick sleeve slides on the outer wall of the thin sleeve, thereby driving the telescopic brush to also change its length. Moreover, the two rubber scrapers also approach or move away from each other, so as to adapt to the cleaning of the inner cavities of different specifications of the same three-phase separator. The two first hydraulic telescopic rods can be extended or shortened simultaneously. When the fixed column is at the axis of the three-phase separator, by changing the lengths of the two first hydraulic telescopic rods, the distance between the telescopic brush and the fixed column can be changed, that is, the radius when the telescopic brush rotates, so as to adapt to three-phase separators of different specifications.

At the upper and lower ends of the outer walls of the two electric telescopic rods 2, two first hydraulic telescopic rods 3 and two second hydraulic telescopic rods 4 are respectively fixedly connected. On the opposite sides of the outer walls of the two first hydraulic telescopic rods 3, a thick sleeve 5 and a thin sleeve 6 are respectively fixedly connected. The thick sleeve 5 is slidably sleeved on the outer wall of the thin sleeve 6. Telescopic brushes 7 are fixedly connected to the outer walls of the thick sleeve 5 and the thin sleeve 6. A plurality of water outlets 8 are opened on the inner walls of the thick sleeve 5 and the thin sleeve 6.

When the lengths of the two electric telescopic rods 2 change, the thick sleeve 5 slides on the outer wall of the thin sleeve 6, thereby driving the telescopic brush 7 to also change its length, so as to adapt to the cleaning of the inner cavities of different specifications of the same three-phase separator. The two first hydraulic telescopic rods 3 can be extended or shortened simultaneously. When the fixed column 1 is at the axis of the three-phase separator, by changing the lengths of the two first hydraulic telescopic rods 3, the distance between the telescopic brush 7 and the fixed column 1 can be changed, that is, the radius when the telescopic brush 7 rotates, so as to adapt to different specifications of three-phase separators.

[0024] In this embodiment: When the rubber scraping plate 9 slides along the inner wall of the three-phase separator, it can not only remove the sundries adhered to the inner wall of the three-phase separator, but also scrape the waste water to one place. When the waste water is scraped to the bottommost part, the water level of the waste water is the highest. At this time, the water pumping tray 10 can suck in the waste water. To adapt to different specifications of three-phase separators, the two rubber scraping plates 9 are slidably connected, so that the working width can be adjusted. The two rubber scraping plates 9 are fixedly connected to the outer walls of the second hydraulic telescopic rods 4, so that the working radius can be adjusted. Among them, the two bidirectional hydraulic telescopic rods 12 play a supporting role.

[0029] As a technical optimization solution of the present utility model, a water supply pipe 17 is connected to one end of the thick sleeve 5, and the other end of the water supply pipe 17 penetrates through the inside of the first hydraulic telescopic rod 3 and the electric telescopic rod 2 on the left side and extends out from the left end of the electric telescopic rod 2 on the left side.

One ends of the two first connecting rings 19 are both rotatably connected with a second connecting ring 20, and the two second connecting rings 20 are both fixedly connected to the outer wall of the respective adjacent bidirectional hydraulic telescopic rod 12.

[0032] In this embodiment: One ends of the water supply pipe 17 and the drain pipe 18 are both fixedly connected with a first connecting ring 19, and the two first connecting rings 19 and the two second connecting rings 20 are rotatably connected respectively.

[0034] In this embodiment: the booster pump 21 is used to inject high-pressure water into the water supply pipe 17, and the pump 22 is used to form a negative pressure in the drain pipe 18. During the operation of the device, the booster pump 21 and the pump 22 are both placed outside the three-phase separator.

[0037] Working principle: When the device is in operation, firstly, the pressure pump 21, the water pump 22 and the remote controller 23 are placed outside the three-phase separator, and the rest of the parts are placed in the cavity of the three-phase separator to be cleaned. Then, the remote controller 23 is operated to extend the two bidirectional hydraulic telescopic rods 12, so that the multiple anti-skid pads 13 abut between the inner walls of the three-phase separator, thereby fixing the device. Then, the two electric telescopic rods 2 are extended by adjustment. As the electric telescopic rods 2 are extended, the thick sleeve 5 slides on the outer wall of the thin sleeve 6, driving the telescopic brush 7 to change its length, and the two rubber scrapers 9 move mutually. Move away and stop after reaching the optimal working width. Next, start the motor 14 to drive the first gear 15 to rotate. During the rotation of the first gear 15, the second gear 16 is driven to rotate, so that the two electric telescopic rods 2 and the fixed column 1 are rotated, thereby driving the two first hydraulic telescopic rods 3 and the two second hydraulic telescopic rods 4 to rotate around the axis of the three-phase separator, so that the telescopic brush 7 and the rubber scraper 9 are rotated. Under the action of the pressure pump 21 and the water pump 22, the telescopic brush 7 is continuously filled with water and scrubbed, the rubber scraper 9 is continuously scraped off debris, and the water pump 10 discharges sewage, thereby achieving a cleaning effect.
