Description

Technical Field

[0001] The utility model relates to a fan heat dissipation auxiliary device for a natural gas compressor, belonging to the technical field of natural gas mining auxiliary equipment. Background Art

[0002] Liquefied Natural Gas (LNG), mainly composed of methane, is recognized as the cleanest fossil energy on earth. It is colorless, odorless, non-toxic and non-corrosive. Its volume is about 1 / 625 of the volume of the same amount of gaseous natural gas, and the mass of liquefied natural gas is only about 45% of the same volume of water.

[0003] After combustion, liquefied natural gas causes very little air pollution and releases a lot of heat, so liquefied natural gas is a relatively advanced energy source.

[0004] Liquefied natural gas is natural gas that has been compressed and cooled to its freezing point (-161.5°C) and becomes liquid. Usually, liquefied natural gas is stored in low-temperature storage tanks at -161.5°C and about 0.1MPa. Its main component is methane, which is transported by special ships or tank trucks and re-gasified when used.

[0005] Due to the following characteristics of liquefied natural gas extraction: the extraction cycle of ordinary extraction points is about 2-3 years. Therefore, most of the ground equipment is installed in containers. For example, the compressor is installed in the container. When one extraction point is completed, the container with ground equipment can be transported to other extraction points for use, saving production costs.

[0006] The compressor needs to dissipate heat in time due to long-term work. In the prior art, an exhaust port is opened on the side wall of the container, and a large fan is installed inside the container near the exhaust port to dissipate heat for the compressor. However, since the natural gas extraction site is in the wild, there is heavy wind, sand and dust. After a long time, a large amount of dust and dirt will accumulate on the fan, resulting in a decrease in the fan's wind speed and a decrease in the fan's heat dissipation effect. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide a natural gas compressor fan heat dissipation auxiliary device to solve the technical problems existing in the above-mentioned prior art.

[0008] The technical solution adopted by the utility model is: a natural gas compressor fan heat dissipation auxiliary device, including a coil arranged between the compressor and the fan, the inlet end of the coil is connected to a three-way pipe through a cleaning pump, a three-way valve is arranged inside the three-way pipe, one branch of the three-way pipe is connected to a cleaning agent, and the other branch of the three-way pipe is connected to clean water; the outlet end of the coil is connected to a nozzle through a pipeline, the number of the nozzles is set to more than one pair, and the same pair of nozzles are symmetrically arranged on both sides of the fan blades.

[0009] Preferably, a fixed cylinder with an axis arranged in a vertical direction is fixed on the compressor, a piston is slidably connected to the inside of the fixed cylinder, the upper end of the piston is connected to the top of the fixed cylinder through a spring, a through hole is provided in the middle of the piston, a telescopic cylinder connected to the through hole is fixed to the lower end of the piston, and the nozzle is fixedly connected to the lower end of the telescopic cylinder.

[0010] Preferably, the number of the springs is set to be more than 2 and they are symmetrically arranged about the axis of the piston.

[0011] Preferably, the nozzle is inclined toward the blades of the fan.

[0012] Preferably, the coil is a copper tube or an aluminum tube.

[0013] Beneficial effects of the utility model: Compared with the prior art, the utility model utilizes the hot air discharged from the compressor to heat the cleaning agent and clean water for cleaning the fan blades, thereby avoiding a decrease in the rotation speed of the fan blades and ensuring the heat dissipation effect of the fan.

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Embodiment 1:

[0019] Natural gas compressor fan cooling auxiliary device, such as Figure 1As shown, it includes a coil 6 arranged between the compressor 1 and the fan, the coil 6 is a copper tube or an aluminum tube, the fan includes a motor 2 and a fan blade 3, the inlet end of the coil 6 is connected to a three-way pipe through a cleaning pump 5 and a pipeline, a three-way valve 4 is arranged inside the three-way pipe, the three-way valve 4 is an automatic valve, one branch of the three-way pipe is connected to a cleaning agent, and the other branch of the three-way pipe is connected to clean water; the outlet end of the coil 6 is connected to a fixed cylinder 7 through a pipeline, the fixed cylinder 7 is fixed above the compressor 1, the axis of the fixed cylinder 7 is arranged in the vertical direction, the interior of the fixed cylinder 7 is slidably connected to a piston 9, the piston 9 is a rectangular parallelepiped, the upper end of the piston 9 is connected to the top of the fixed cylinder 7 through a spring 8, the number of springs 8 is set to 2 and is symmetrical about the axis of the piston 9, a through hole is set in the middle of the piston 9, the lower end of the piston 9 is fixed with a telescopic cylinder 10 connected to the through hole, the lower end of the telescopic cylinder 10 is fixedly connected with a nozzle, and the nozzle is inclined toward the fan blade 3 of the fan;

[0020] A fixed cylinder 7, a piston 9, a telescopic cylinder 10 and a nozzle constitute a cleaning mechanism. In this embodiment, the number of cleaning mechanisms is set to two, and the nozzles of the two cleaning mechanisms are symmetrically arranged on both sides of the fan blades 3.

[0021] In this embodiment, a through hole is provided on the portion of the compressor 1 located on the left side of the fan blade 3 to allow the telescopic cylinder 10 on the left side to pass through.

[0022] When the fan blades 3 need to be cleaned, the cleaning agent is pumped into the coil 6 by using the three-way valve 4 and the cleaning pump 5, and the cleaning agent in the coil 6 is heated by the heat exchange between the hot air discharged from the compressor 1 and the coil 6, and then the speed of the motor 2 is reduced to make the fan blades 3 rotate slowly; similarly, clean water is pumped into the coil 6 by using the three-way valve 4 and the cleaning pump 5. During this process, the heated cleaning agent in the coil 6 is discharged into the fixed cylinder 7, and the liquid pressure pushes the piston 9 to slide downward, so that the telescopic cylinder 10 extends downward and drives the nozzle to move downward, and the nozzle sprays the hot cleaning agent onto the fan blades 3, and the fan blades 3 rotate slowly. Rotate to ensure that all parts of the fan blade 3 can be sprayed with the cleaning agent. After the cleaning agent is sprayed, turn off the cleaning pump 5, and the inside of the coil 6 is all clean water. Wait for a few minutes to allow the cleaning agent to fully react with the dirt on the fan blade 3, and the cold water in the coil 6 is heated; then, start the cleaning pump 5 again, increase the speed of the motor 2, and similarly drain the hot water in the coil 6 to rinse the fan blade 3. After rinsing, turn off the cleaning pump 5, adjust the speed of the motor 2 to the normal speed, and the water on the fan blade 3 is removed under the action of centrifugal force, and the fan blade 3 automatically dries. After the cleaning pump 5 stops, the piston 9 is reset under the elastic force of the spring 8 to prevent the nozzle from blocking the fan blade 3.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present utility model, which should be included in the protection scope of the present utility model.
