Detailed Implementation

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, an air power station for an offshore oil platform includes an air supply skid 20 and an air receiving and control skid 21. The air supply skid 20 includes an air compressor 1, a primary filter 2, and a first air dryer 3. The air outlet of the air compressor 1 is sequentially connected to the primary filter 2 and the first air dryer 3 through pipelines. The air outlet of the first air dryer 3 is connected to the air receiving and control skid 21 through pipelines.

[0022] The air receiving and control skid 21 includes an air cylinder 5, a primary air supply controller, a second air dryer 6, a secondary filter 7, and a secondary air supply controller. The air inlet of the air cylinder 5 is connected to the air outlet of the first air dryer 3. The air inlet of the air cylinder 5 is connected to the primary air supply controller and the second air dryer 6 via pipelines. The primary air supply controller is located on the main deck of the offshore oil platform and is used to connect pneumatic tools and equipment. The second air dryer 6 is connected to the secondary filter 7 and the secondary air supply controller sequentially via pipelines. The secondary air supply controller is used to connect to the pure drying pneumatic equipment. The pure drying pneumatic equipment includes painting equipment, an electromechanical equipment control air source, and a wellhead blowout preventer pneumatic control valve assembly. All of these devices require high-quality compressed air as their power source. Improving the cleanliness and dryness of the air through the primary filter, the first and second air dryers, and the secondary filter ensures the cleanliness and dryness of the air supply system, effectively guaranteeing the rapid response performance of pneumatic components and avoiding the risk of malfunctions such as control signal delays and valve core jamming caused by air source contamination.

[0023] In this preferred embodiment, the first air dryer is a refrigerated dryer, model KPTER16FH; the second air dryer is a heatless regenerative dryer, model KPTEH30; and the air compressor is an air-cooled oil-free air compressor, model Ingersoll Rand SM90. Considering the high ambient temperature conditions in marine environments, the air compressor, dryer, and their electrical equipment are all made of high-temperature resistant materials. Furthermore, to address potential overheating issues, the air compressor, the first air dryer, and the second air dryer all have enhanced cooling measures to ensure stable and efficient operation of the equipment in high-temperature environments.

[0024] The working principle of an air power station on an offshore oil platform is as follows: Compressed air is generated by an air compressor, and moisture, dust, and impurities are removed from the air through a refrigerated dryer and a primary filter. The air is then stored in air cylinders and supplied in one direction to pneumatic tools and equipment. Another direction supplies compressed air to pneumatic equipment requiring even purer and drier air through a heatless regenerative dryer and a secondary filter, ensuring the normal operation of the equipment.

[0025] The primary air supply controller includes a first manifold 22, a gate valve 12, and multiple first manifold ball valves 11. The gate valve 12 and the ball valves 11 are connected to the first manifold 22. A pressure gauge is installed on the first manifold 22, and a deck vent plug 10 is installed at the lower end of the first manifold 22. Pneumatic tools and equipment are supplied with air through the first manifold 22 and the ball valves 11. The pressure gauge 9 monitors the pressure in the second manifold 23. The equipment is low-cost, and the control via the gate valve 12 improves safety.

[0026] The secondary air supply controller includes a second manifold 23 and multiple second manifold ball valves 8, which are respectively connected to the second manifold 23. A pressure gauge 9 is installed on the second manifold 23. The second manifold 23 and the multiple ball valves 8 supply air to pneumatic equipment that requires cleaner and drier air, and the pressure gauge 9 monitors the pressure inside the second manifold 23.

[0027] A first ball valve 13 is installed on the air inlet pipe of the primary air supply controller, and a second ball valve 14 is installed on the air inlet pipe of the second air dryer 6; a third ball valve 15 is installed on the air inlet pipe of the secondary air supply controller. The first ball valve 13 controls the connection and disconnection of the air inlet pipe of the primary air supply controller, the second ball valve 14 controls the connection and disconnection of the air inlet pipe of the second air dryer 6, and the third ball valve 15 controls the connection and disconnection of the air inlet pipe of the secondary air supply controller.

[0028] Ball valves are installed on the air inlet pipe and the air delivery pipe of the air cylinder 5, respectively, and a pressure gauge is installed on the air cylinder 5. The ball valves control the connection and disconnection of the air inlet pipe and the air delivery pipe of the air cylinder 5, and the pressure gauge monitors the pressure inside the air cylinder 5.

[0029] Ball valves 4 are respectively installed on the inlet and outlet pipes of the first air dryer 3. Ball valves 4 are also installed on the pipeline between the first air dryer 3 and the air bottle 5. The ball valves control the connection and disconnection of the inlet and outlet pipes of the first air dryer 3, and also control the connection and disconnection of the pipeline between the first air dryer 3 and the air bottle 5.

[0030] An air power station for an offshore oil platform provides two compressed air supplies via an air supply skid and an air receiving control skid. One supply provides compressed air to pneumatic tools and equipment on the offshore platform, while the other supplies compressed air to pneumatic equipment requiring cleaner and drier air. The station is rationally designed to supply air to different levels of equipment, reducing production costs and ensuring normal equipment operation. It utilizes an oil-free air compressor and a refrigerated dryer, making it suitable for high-temperature areas at sea.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
