Description

Technical Field

[0001] The utility model relates to a water seal replenishing device for a storage tank top, belonging to the technical field of tank body sealing. Background Art

[0002] In the production of chemical enterprises, storage tanks for raw materials, intermediates and finished products are indispensable. A water seal is installed on the top of the storage tank. The water seal on the top of the tank is a safety protection device. Its main functions include: preventing oil and gas leakage. During the operation of the oil storage tank, the water seal can prevent oil and gas from leaking out from the top of the tank, preventing oil and gas from evaporating into the air, causing environmental pollution and fire and explosion risks; preventing air from entering. The water seal can prevent external air from entering the tank through the top of the tank, maintaining the stability of the oil and gas mixture in the tank, reducing oxidation reactions, and reducing the risk of spontaneous combustion. The water seal forms an isolation layer to isolate the internal and external environments of the tank, isolating the oil and gas in the tank from the external environment, reducing the chance of contact between the oil and gas in the tank and external fire sources, and improving safety.

[0003] In general, the water seal on the top of the oil storage tank is an important component to ensure the safe operation of the oil storage tank. It reduces the risk of oil and gas leakage and fire and explosion through physical isolation, and protects the safety of personnel and facilities.

[0004] At present, adding water to the water seal on the tank top requires manual work of climbing to the top of each tank one by one to add water. For production enterprises with relatively more storage tanks, the labor intensity of employees' daily tank top water seal replenishment operations is relatively high, especially in the summer when the temperature is high and the water seal is added frequently, which increases the labor intensity. If water is not replenished in time, on the one hand, the odor will evaporate and pollute the environment. On the other hand, for storage tanks storing some flammable and explosive materials, air may enter the tank, causing safety hazards. Utility Model Content

[0005] The utility model aims to solve the technical problems of high labor intensity and untimely replenishment of water in the prior art, and provides a water-seal replenishment device for a storage tank top.

[0006] The utility model is realized through the following technical solutions:

[0007] That is, a tank top water seal replenishment device, including tank top oil seals arranged at the top of oil tank one and oil tank two, and also including a water tank and a water replenishment pump connected to each other. The water outlet of the water replenishment pump is connected to two water replenishment pipes, the ends of the water replenishment pipes are connected to the tank top oil seals, and the water replenishment pipes are also provided with water replenishment valves. A liquid level sensor is provided in the tank top oil seal, and the tank top oil seal is connected to an overflow tank through an overflow water pipe.

[0008] The liquid level sensor is used to monitor the water level in the tank top oil seal in real time. Once the water level is lower than the minimum required water level, the liquid level sensor will sound an alarm, and the operator will start the water replenishment pump to replenish water into the tank top oil seal. After the water is replenished, the water replenishment pump will be turned off. When the utility model is used to replenish water in the tank top oil seal, the operator has low labor intensity, is easy to achieve timely water replenishment, and avoids pollution and safety hazards.

[0009] Further preferably, the utility model further comprises a controller, the controller being electrically connected to the water replenishment pump. The water replenishment pump can be automatically controlled by the controller, thereby improving the automation level of the utility model.

[0010] Further preferably, the water replenishment valve is a solenoid valve, and the water replenishment valve is electrically connected to the water replenishment pump. The water replenishment valve is automatically controlled by the controller, and the water replenishment amount can be controlled with higher accuracy than directly controlling the opening and closing of the water replenishment pump.
