Description

[Technical field]

[0001] The utility model relates to the field of liquid drainage, in particular to an automatic drainage device for an emergency pool in an oil depot accident. [Background Technology]

[0002] Oil depots often store large quantities of flammable and explosive refined oil products. Oil leaks or fires can easily cause environmental pollution or explosions, potentially triggering sudden environmental incidents or major safety accidents. Oil depot emergency pools are semi-underground emergency facilities primarily used to collect environmentally harmful foam wastewater and leaked oil after drills, oil leaks, fires, or explosions. Most oil depots have implemented emergency pools to handle foam wastewater, sudden environmental incidents, or accidents.

[0003] After daily drills, sudden environmental events or accidents, foam liquid wastewater or leaked oil flows from the storage tank area through the drainage system and finally flows to the accident emergency pool, which is stored and controlled by the accident emergency pool to prevent it from flowing and overflowing. When designing the accident emergency pool, it is generally designed through calculation based on the maximum amount of liquid that may leak from the finished oil in the storage tank. Therefore, the volume of the accident emergency pool is generally large. Moreover, in order to reduce the floor space occupied by the construction of the accident emergency pool and make the accident emergency pool have the function of storing a large amount of liquid, the depth of the accident emergency pool is generally large. In order to reduce investment costs, the accident emergency pool is used as a rainwater collection pool on a daily basis. A manual valve is set at the outlet of the drainage ditch to the entrance of the accident emergency pool and at the outlet of the accident emergency pool to the external discharge. The inlet valve from the outlet of the drainage ditch to the entrance of the accident emergency pool is set to normally open, and the outlet valve from the accident emergency pool to the external discharge is set to normally closed, and daily operations are often required. The existing technology has the following disadvantages:

[0004] 1. Under normal circumstances, the accident emergency pool is used as a rainwater collection pool. During the flood season or heavy rain, short-term heavy rainfall is frequent and relatively scattered. After each rainfall, all rainwater in the reservoir area will be collected into the accident emergency pool through the drainage system. The accident emergency pool has a large amount of rainwater storage and is prone to overflowing. The outlet valve needs to be opened frequently for drainage. When the weather is relatively dry and there is less rain, the evaporation of rainwater in the accident emergency pool is relatively large, and the water storage in the pool is reduced. It is necessary to manually close the outlet valve in advance to control the discharge of water and avoid the water in the pool being drained. At the same time, when the water storage in the accident emergency pool is already low, it is also necessary to close the inlet valve and fill the pool with water for maintenance to prevent the bottom of the accident emergency pool from being cracked due to lack of water and exposure to the sun.

[0005] 2. When an emergency occurs, emergency response personnel often need to go to the accident emergency pool site to confirm the status of the outlet valve in a very short time. They cannot immediately realize the opening and closing control of the accident emergency pool outlet valve. In addition, the operating speed of the operator is required to be high, and the safety factor is low.

[0006] 3. The area and depth of the accident emergency pool are generally large, and it is often necessary to observe the water level with the naked eye or monitor the water volume in real time on site to control the water level in the pool from exceeding the safe water level to not falling below the minimum water level. However, there are errors in visual observation of the water level.

[0007] 4. The storage capacity of the accident emergency pool is relatively limited. When the liquid in the accident emergency pool reaches the storage capacity, it needs to be drained in time to avoid overflow. However, the drainage control is still not real-time control. Generally, manual drainage is used, and the operator needs to keep an eye on the water level of the accident emergency pool at all times, which puts a huge burden on the operator, and the drainage volume is difficult to control;

[0008] 5. Because the manual outlet valve is located below the valve well, operators need to go down the well to open and close the valve. This is considered confined space operation and requires approval and on-site supervision. The operation is dangerous and the frequency of operation is high. The frequent opening and closing of the valve increases the risk of accidents. If an accident occurs, manual drainage will also pose safety risks and the manual operation time is long. [Utility Model Content]

[0009] The purpose of the utility model is to provide an automatic drainage device for an oil depot accident emergency pool, which solves the problems of the accident emergency pool being unable to drain automatically, wasting manpower and potential safety hazards caused by untimely drainage.

[0011] Furthermore, the drainage siphon device is provided with a support column for supporting and fixing the entire siphon device.

[0012] Furthermore, the water inlet of the water inlet section is vertically arranged at the bottom of the emergency pool, and the water inlet of the water inlet section is at least 30CM high from the bottom of the emergency pool.

[0013] Furthermore, the water outlet section is horizontally arranged at the bottom of the emergency pool, the water outlet section is at least 10CM high from the bottom of the emergency pool, and the vertical height difference between the water inlet and the water outlet section of the siphon tube water inlet section is at least 20CM.

[0014] Furthermore, the length of the ventilation pipe is higher than the height of the emergency pool. The ventilation pipe is a hot-dip galvanized seamless steel pipe with a height of 3.9 meters.

[0015] Furthermore, the vertical length of the water inlet section is 70CM, and the horizontal length of the siphon pipe is 1.2M.

[0016] Furthermore, the second manual valve of the extension rod is 0.6M above the ground.

[0017] Furthermore, the vertical tube has a height of 90 cm.

[0018] Compared with the prior art, the automatic drainage device for the oil depot accident emergency pool described in the utility model utilizes the siphon effect.

[0025] Please refer to Figure 1 The embodiment provides an oil depot accident emergency pool automatic drainage device, the device is used for oil depot accident emergency pool automatic drainage, and the device comprises a drainage siphon device, the drainage siphon device 1 is connected and composed of a water inlet section 10, a pipe body section and a water outlet section 13, the pipe body section is composed of a horizontal pipe 11 and a vertical pipe 12, the vertical pipe 12 of the pipe body section is provided with a vent 14, the vent 14 is connected with a vent pipe 15, and the vent pipe 15 is provided with a discharge ball valve 16; the water outlet section 13 is provided with a first manual valve 17, the manual valve is provided with an extension rod 18, and the extension rod 18 is provided with a second manual valve 19. The drainage siphon device is provided with a support column 20 for supporting and fixing the whole siphon device. The water inlet of the water inlet section is vertically arranged at the bottom of the emergency pool, and the water outlet section is horizontally arranged at the bottom of the emergency pool.
