A water injection intelligent emergency management system

Abstract

The present invention relates to the technical field of emergency treatment of gas leakage. The present invention provides an intelligent water injection emergency management method and system. When in use, the gas concentration detector detects the liquefied petroleum gas concentration in the storage area of ​​the liquefied petroleum gas storage tank. When the gas concentration reaches the warning threshold, the fire source is isolated and it is determined whether water injection is needed. After confirmation, the water injection pump is started to transport the water medium in the water supply tank to the gas storage tank, and the automatic valve is controlled to guide the gas in the storage tank, and the water-liquid replacement is adjusted by pressure. The water medium enters the bottom of the storage tank, and the liquefied petroleum gas in the storage tank floats on the top. As the water medium in the storage tank gradually increases, the liquefied petroleum gas in the storage tank flows to the receiving tank through the gas phase pipeline until the liquefied petroleum gas in the storage tank is completely transported to the receiving tank, which can quickly stop the leak and stabilize the dangerous situation, and quickly transfer the liquefied petroleum gas in the leaking storage tank, reduce the escape of liquefied petroleum gas, and reduce energy loss.

Description

Technical Field

[0001] The invention relates to the technical field of gas leakage emergency treatment, and in particular to an intelligent water injection emergency management system. Background Art

[0002] The safety of liquefied petroleum gas storage tanks is very important. If liquefied petroleum gas leaks, it may cause explosion and fire, threatening the lives of people. Common leakage sites of storage tanks include leakage of pressure pipes or flange valves, leakage of the tank body or the valves or pipes connected to it, leakage at the bottom of the tank body, or leakage of the first valve adjacent to the tank body. The conventional practice is to manually open the valve and pump to inject water.

[0003] However, the applicant has found that the prior art has at least the following problems:

[0004] Failure to isolate and protect after a liquefied petroleum gas leak to reduce the concentration of liquefied petroleum gas in the air may result in external fire hazards and prevent explosions;

[0005] If the liquefied petroleum gas in the leaking tank cannot be transferred in time, the liquefied petroleum gas will vaporize quickly, causing a low-temperature environment. Not only can personnel not get close to the rescue, but the low temperature will also damage other equipment, causing secondary hazards.

[0006] Even if conventional water injection is successful, it only solves the front-end problem. There is no systematic method for tank replacement, which is not feasible.

[0007] When injecting water, if the pressure and liquid level are not properly controlled, incomplete replacement or even explosion may occur. Summary of the invention

[0008] In view of this, the purpose of the present invention is to propose an intelligent water injection emergency management system to solve the problem that the liquefied petroleum gas in the leaking storage tank cannot be transferred in time, and a large amount of liquefied petroleum gas escapes into the air, causing danger.

[0009] Based on the above purpose, the present invention provides an intelligent water injection emergency management method, comprising:

[0010] Obtain the abnormal concentration of combustible gas in the storage tank area and obtain abnormal data;

[0011] According to the abnormal concentration of combustible gas, the storage tank area is cut off, water curtain dilution and isolation protection are carried out, and the combustible gas situation and tank data of the storage tank area after dilution and isolation protection are recorded to generate comparative data;

[0012] Compare and analyze the comparison data with the abnormal data to determine whether water injection is needed;

[0013] After determining that water injection is needed, the water medium is transported to the storage tank, and the gas in the storage tank is guided at the same time, and water-liquid replacement is performed through pressure regulation.

[0014] Optionally, the abnormal concentration of combustible gas in the storage tank area is obtained to obtain abnormal data including:

[0015] Detect the combustible gas concentration in the tank area and compare it with the preset warning value. If it exceeds the preset warning value, the situation is abnormal, an alarm is issued, and the abnormal data is recorded; if it does not exceed the preset warning value, the situation is judged to be normal.

[0016] Optionally, the storage tank area is diluted and isolated for protection according to the abnormal concentration of combustible gas, and the combustible gas situation of the storage tank area after dilution and isolation protection is recorded, and the comparative data generated includes:

[0020] The comparison data of the current data conditions will be compared, calculated and analyzed with the abnormal data before dilution and isolation protection. At the same time, the production data and monitoring data of the tank area will be captured to analyze and determine whether the leakage point is located on the tank body.

[0021] Optionally, the comparison data is compared with the abnormal data for analysis to determine whether water injection is needed, including:

[0022] When the internal shut-off valve in the tank area works, the concentration of combustible gas gradually decreases, and the other data of the tank remain basically unchanged, it is judged that there is a leak outside the tank body, and water curtain and spray dilution are continued until the concentration is reduced to below the safe value;

[0023] When the internal cut-off valve in the tank area works, the concentration of combustible gas continues to increase or cannot be reduced, the tank pressure decreases significantly, and the liquid level changes basically do not change, it is judged that the tank body is leaking gas phase, dilute the leaking point, perform regular tank emptying, and empty the liquid as much as possible;

[0024] When the internal shut-off valve in the tank area works, the concentration of combustible gas continues to increase or cannot be reduced, the tank pressure does not decrease significantly, and the liquid level decreases, it is judged that there is a liquid phase leak in the tank body, and the tank is filled with water for replacement.

[0025] Optionally, after determining that water injection is required, the water medium is transported to the storage tank, and the gas in the storage tank is directed, and water-liquid replacement is performed through pressure regulation, including:

[0026] Based on the current storage volume of the leaking tank, recommend a tank with low pressure and low liquid level to the on-site operator for confirmation;

[0027] Obtain confirmation information and choose whether to open the leaking tank and the receiving tank for pressure equalization according to the pressure difference between the two tanks;

[0028] After the pressure is equalized, the water injection pump is pressurized according to the tank pressure and the water injection pressure difference setting value, the pressure difference is controlled to inject water, and the current storage volume of the accident tank is recorded;

[0029] Open the automatic valves of the gas pipelines of the receiving tank and the leakage tank;

[0030] Lift the liquefied gas in the accident tank to the height of the gas phase pipe of the storage tank, and export the liquefied gas to the receiving tank through the gas phase pipe of the accident tank until the liquid level height of the receiving tank reaches the preset position of the system. It will then prompt that the tank has been completely emptied and the valve of the receiving tank will be automatically closed.

[0031] Later, close the gas phase valve of the accident pipe and continue to apply pressure through the water injection port until the water medium overflows from the safety valve. The accident tank is then replaced, the valve and pump are closed, and the accident tank maintenance procedure begins.

[0032] The present invention also provides an intelligent water injection emergency management system, comprising:

[0033] Tank area for storing liquefied petroleum gas;

[0034] The gas concentration detector is used to detect the concentration of combustible gas in the storage tank area and compare the detected value with the preset warning value. If it exceeds the preset warning value, an alarm will be issued, otherwise a cyclic detection will be performed;

[0043] Optionally, the water injection module includes:

[0044] The judgment unit is used to judge the leaking point of the combustible gas. If the leak is outside the storage tank body, the water curtain and spray dilution will continue until the concentration of the combustible gas drops to a safe value; if the leak is from the gas phase of the tank body, the leaking point will be diluted and the conventional tank emptying operation will be performed to empty the liquid as much as possible; if the leak is from the liquid phase of the storage tank body, the storage tank will be replaced by water injection;

At the same time, the system controls the automatic valve to guide the gas in the storage tank and adjusts the water-liquid replacement through pressure.

[0049] When water medium enters the storage tank, since water medium is immiscible with liquefied petroleum gas in the storage tank and the water medium has a greater density than liquefied petroleum gas, water medium enters the bottom of the storage tank and liquefied petroleum gas in the storage tank floats on top. As the amount of water medium in the storage tank gradually increases, the liquefied petroleum gas in the accident tank flows to the receiving tank through the gas phase pipeline until the liquefied petroleum gas in the accident tank is completely transported to the receiving tank, which can quickly stop the leak and stabilize the dangerous situation, and quickly transport the liquefied petroleum gas in the leaking storage tank, reduce the escape of liquefied petroleum gas, and reduce safety hazards.
