Description

[0001] This invention belongs to the technical field of oil tanks for offshore wind farm booster stations, and particularly relates to an emergency oil tank and its usage method for a modular prefabricated offshore wind farm booster station. Background Technology

[0002] Offshore wind farm booster stations are typically used for voltage level transformation. For oil-cooled transformers, the cooling oil is usually collected in emergency oil tanks. These tanks generate significant heat during operation. If not cooled promptly, the oil and gas temperature inside the tanks will remain high. Under these high temperatures, the tank materials may expand or deform, leading to structural damage and increased ambient temperature, threatening the safety of equipment and personnel. Furthermore, the oil in the emergency tanks is prone to vaporization and explosion at high temperatures, increasing the risk of fire and explosion. Additionally, the traditional method of introducing air into the tanks via pipelines can cause a highly explosive reaction, resulting in significant oil pollution of the surrounding marine environment and damage to the offshore wind farm booster station.

[0003] Summary of the Invention

[0004] The purpose of this invention is to provide an emergency oil tank and its usage method for a modular prefabricated offshore wind farm booster station, in order to overcome the shortcomings of existing oil tanks.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A further improvement of the present invention is that the end of the water supply pipe away from the water pump extends to the bottom of the outer protective tank and passes through the side wall of the outer protective tank to communicate with the outer protective tank. The middle position of the water supply pipe is located inside the refrigeration unit, and the water supply pipe is arranged in an S-shape.

[0012] A further improvement of the present invention is that the connecting plate is an annular plate with an opening at the top, and a connecting groove is provided on the side of the connecting plate away from the opening. The connecting groove is located at the lowest point inside the outer protective tank, and the cooling water between each connecting plate flows through the connecting groove.

[0013] A further improvement of the present invention is that a climbing ladder is provided on the outer side wall of the outer protective tank, an observation tube is provided above the outer protective tank, the lower end of the observation tube passes through the side wall of the outer protective tank and the side wall of the inner protective tank in sequence, and communicates with the inner protective tank. The side walls of the outer protective tank and the side walls of the inner protective tank are both fixedly connected to the observation tube, a sealing door is provided on the observation tube, and the observation tube is located above the climbing ladder.

[0014] A further improvement of the present invention is that a gas guide pipe and a pressure relief pipe are provided above the outer protective tank. The lower ends of the gas guide pipe and the pressure relief pipe pass through the side wall of the outer protective tank and the side wall of the inner protective tank in sequence and are connected to the inner protective tank. The side walls of the outer protective tank and the inner protective tank are fixedly connected to the gas guide pipe and the pressure relief pipe. A carbon dioxide generator is provided at the upper end of the gas guide pipe, and a pressure relief valve is provided on the pressure relief pipe. An oxygen concentration detection sensor is located near the pressure relief pipe.

[0015] A further improvement of the present invention is that the flow divider is located inside the refrigerator. The flow divider includes a flow divider column and a flow divider baffle. The upper end of the flow divider column is conical. Several flow divider baffles are evenly arranged on the side wall of the flow divider column. The flow divider baffles are fixed on the side wall of the flow divider column.

[0018] A method for using an emergency oil tank in a modular prefabricated offshore wind farm booster station, the method comprising:

[0019] The oxygen concentration inside the inner protective tank is detected by an oxygen concentration sensor. When the oxygen concentration is high, carbon dioxide gas is introduced into the inner protective tank to expel the gas and ensure that the oxygen concentration inside the inner protective tank is at a safe level. A refrigeration unit is used to cool the oil and gas passing through the feed pipe, and a flow divider is used to separate the oil and gas. A spray device performs water cooling on the inner protective tank. The internal temperature of the oil and gas is monitored in real time by a temperature sensor inside the inner protective tank. A liquid level sensor is used to detect the internal oil level to avoid overfilling. A pressure sensor is used to monitor the internal pressure to ensure that the pressure inside the inner protective tank is at a safe level.

[0020] Compared with the prior art, the present invention has at least the following beneficial technical effects:

[0021] This invention provides an emergency oil tank for a modular prefabricated offshore wind farm booster station. It features a double-layer structure with an outer and inner protective tank. The inner protective tank stores oil and gas. A refrigeration unit is installed outside the unit to cool the feed pipe. Simultaneously, a spray system is installed on the outside of the inner protective tank for water cooling. Working in conjunction with the refrigeration unit, this system effectively cools the oil and gas. A water supply pipe passes through the refrigeration unit to cool the water after spray cooling, improving subsequent cooling efficiency and preventing safety hazards caused by high internal temperatures in the inner protective tank, thus avoiding impact on oil and gas quality. An oxygen detection sensor is installed inside the inner protective tank to monitor the internal oxygen concentration in real time.

[0022] Furthermore, cooling water is installed inside the outer protective tank. The cooling water inside the outer protective tank is sprayed out through the spray nozzles on the spray pipe by using a water supply pipe, water pump, water inlet pipe, connecting pipe and spray pipe.

[0023] Furthermore, by using a carbon dioxide generator and a gas delivery pipe together, when the oxygen concentration exceeds the standard, carbon dioxide inert gas is introduced into the inner protective tank to reduce the oxygen concentration, thereby avoiding the problem that a high oxygen concentration in the inner protective tank can easily lead to an explosion.

[0024] Furthermore, a pressure balancing airbag is installed on the outer protective tube. When the internal pressure between the outer and inner protective tanks changes with temperature, it plays a role in balancing the air pressure, thereby preventing damage to the outer protective tank caused by excessive or insufficient internal pressure.

[0025] This invention provides a method for using an emergency oil tank in a modular prefabricated offshore wind farm booster station. An oxygen concentration sensor inside the inner protective tank detects the oxygen concentration. When the oxygen concentration is high, a carbon dioxide generator and pressure relief valve are controlled via the main control box to introduce carbon dioxide gas into the inner protective tank, discharging the gas inside and ensuring the oxygen concentration remains at a safe level. This avoids the risk of explosion due to high oxygen concentration. A refrigeration unit cools the oil and gas passing through the feed pipe, while a flow divider separates the oil and gas, improving the cooling effect of the refrigeration unit. A spray system further cools the inner protective tank with water, working in conjunction with the refrigeration unit to achieve the desired cooling effect. The water cooled by the spray system is then cooled to improve subsequent cooling efficiency, thus avoiding safety hazards caused by high internal temperatures and ensuring the quality of the oil and gas. A temperature sensor inside the inner protective tank monitors the internal oil and gas temperature in real time, and a level sensor detects the internal oil level to prevent overfilling.
