Description

Technical Field

[0001] The present invention relates to the technical field of oil and gas gathering and transportation systems, and in particular to an intelligent fire extinguishing device and system for oil and gas gathering and transportation systems. Background Art

[0002] In the oil and gas gathering and transportation system, the oil pump in the oil pump room is the hub of fuel storage and transportation, used to transport crude oil, natural gas, liquefied petroleum gas and natural gasoline. In the transportation of natural gas, the oil pump is also called a booster station or a pressure station. The fuel transported by the oil pump is flammable, explosive and corrosive. The connection of the oil pump group, between the pump shaft and the pump housing, and the shaft seal are too tight, causing the oil pump to run idle, overheat and smoke. The connection between the pump body and the pipeline, the pump housing and the balance pipe are all prone to leakage. The corrosion and rupture may cause fuel leakage. If there is an open flame or the oil pump shaft rubs or hits to generate sparks and cause combustion, the fire risk is extremely high. It is one of the places where accidents are prone to occur, so the oil pump room has always been the focus of safety production and firefighting work.

[0003] At present, the main emergency fire extinguishing measures in the oil pump room are mechanical trigger type, such as hanging a hanging dry powder fire extinguisher above the pump room, which is triggered by the expansion and shattering of the temperature-sensitive glass tube due to heat. The triggering mechanism of the hanging dry powder fire extinguisher is relatively lagging and the capacity is limited, so its fire extinguishing coverage and fire extinguishing effect are extremely limited. The oil pump itself has a large flow rate, and the diffusion area after leakage is large. After the fire occurs, the fire spreads rapidly, and the current fire extinguishing devices cannot meet this requirement. Summary of the invention

[0004] The present invention provides an intelligent fire extinguishing device and system for an oil and gas gathering and transportation system, which monitors the fire condition of each oil pump unit in real time, controls the fire extinguishing agent tank to spray the fire extinguishing agent on each oil pump unit individually to extinguish the fire, and can quickly and effectively extinguish the fire of the oil pump in the early stage of the fire, thus preventing it from happening.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0028] See also Figure 1 The present invention provides an intelligent fire extinguishing device for an oil and gas gathering and transportation system, in one embodiment, comprising:

[0029] The fire extinguishing agent tank 01 is used to contain the fire extinguishing agent. Specifically, the fire extinguishing agent can be water fire extinguishing agent, dry powder fire extinguishing agent, foam fire extinguishing agent, carbon dioxide fire extinguishing agent, halogenated hydrocarbon fire extinguishing agent, etc., which is not limited in this embodiment.

[0030] The oil and gas gathering and transportation system refers to a system that collects and transports crude oil, natural gas, liquefied petroleum gas or natural gasoline extracted from oil fields. The intelligent fire extinguishing device of the oil and gas gathering and transportation system is an intelligent fire extinguishing device that can be used in any gathering and transportation system such as crude oil, natural gas, liquefied petroleum gas or natural gasoline.

[0031] The fire extinguishing agent delivery pipeline includes a main pipeline 02 and a pipeline branch 03. One end of the main pipeline 02 is connected to the fire extinguishing agent tank 01, and the other end is extended above the oil pump unit 100 along the arrangement direction of the oil pump unit 100. The pipeline branch 03 of the main pipeline 02 is arranged parallel to the body direction of the oil pump unit 100 through an electric valve directly above each oil pump unit 100, and a fire extinguishing agent nozzle 04 is arranged on each pipeline branch 03 toward the corresponding oil pump unit.

[0032] Specifically, the fire extinguishing mechanism of the intelligent fire extinguishing device of the oil and gas gathering and transportation system includes water inlet type and water-free type. Figure 1 This is a schematic diagram of the water-free structure. Figure 2 It is a schematic diagram of the water-inlet structure.

[0033] The water-free fire extinguishing agent is provided by a fire extinguishing agent tank, which can be specifically a foam fire extinguishing agent. The water-inlet intelligent fire extinguishing device also includes a water inlet pipe 05, the water inlet of the water inlet pipe 05 is used to connect to a fire-fighting water source, and the water outlet of the water inlet pipe 05 is arranged above the oil pump unit 100 and extends along the arrangement direction of the oil pump unit 100 to form a main pipe 02 of the fire extinguishing agent delivery pipe. The fire extinguishing agent tank body 01 is connected to the main pipe 02 through a valve 06 and a capillary pipe 07, so that the fire extinguishing agent in the fire extinguishing agent tank body 01 is mixed with water to form a mixed fire extinguishing agent, and then transported to each oil pump unit 100 along the main pipe 02 and the pipe branch 03.

[0034] The two different fire extinguishing agent mechanisms can be suitable for different application scenarios, enhancing the practicality of the intelligent fire extinguishing device of the oil and gas gathering and transportation system.

[0035] A plurality of groups of flame detection sensors 08 , each group of flame detection sensors 08 is arranged on a pipeline branch 03 , and is used to monitor the fire condition of the corresponding oil pump unit 100 .

[0036] The controller is respectively connected to the electric valve of the main pipeline 02, the electric valve of each pipeline branch 03 and each group of flame detection sensors 08, and is used to control the opening of the electric valve of the main pipeline 02 and the electric valve of the corresponding pipeline branch 03 according to the fire detection signal detected by each group of flame detection sensors 08, so as to extinguish the fire of the oil pump unit 100 separately.

[0037] Specifically, the electric valve of the main pipeline is an electric butterfly valve, and the electric valve of the pipeline branch is an electric ball valve. Both the electric butterfly valve and the electric ball valve can control the opening of the valve through an electrical signal.

[0038] The intelligent fire extinguishing device of this embodiment constructs an automatic fire extinguishing mechanism based on the fire extinguishing agent tank. In specific applications, the number, size and capacity of the fire extinguishing agent tank can be set according to the actual needs of the oil pump room, fully meeting the metering requirements of fire extinguishing materials in actual fire extinguishing scenarios and achieving effective fire extinguishing. Compared with the trigger mechanism of the suspended dry powder fire extinguisher, the fire extinguishing agent tank has a larger capacity and is more convenient to replenish, thereby achieving effective fire extinguishing.

[0039] The intelligent fire extinguishing device sets up pipeline branches on the main pipeline, and sets up flame detection sensors and electric valves on each pipeline branch and connects them to the controller. Each pipeline branch can be controlled individually, so that one fire extinguishing agent tank can perform unified fire monitoring and separate fire extinguishing treatment on a group of oil pump units. The fire monitoring is accurate and controllable, with a fast response speed. The oil pump can be quickly and effectively extinguished at the early stage of the fire to prevent it from happening. At the same time, the targeted delivery and unified management of fire extinguishing agents improves the effective utilization rate of fire extinguishing agents and saves material resources.

[0040] In one embodiment, the controller is further used to cut off the power supply of the oil pump unit 100 in which the fire occurs, and the oil pump unit stops working. When a fire occurs, timely cutting off the power supply of the oil pump unit can effectively protect the oil pump unit from further damage, improve the safety performance of the oil pump unit, and prevent a larger fire accident.

[0041] In one embodiment, the controller includes a master controller 09 and several branch sub-controllers 10, the master controller 09 is arranged at the end of the fire extinguishing agent tank 01, each branch sub-controller 10 is respectively arranged on a pipeline branch 03, one end of each branch sub-controller 10 is respectively connected to a group of flame detection sensors 08 and electric valves on the corresponding pipeline branch 03, and the other end is connected to the master controller 09, each branch sub-controller 10 is respectively used to receive the detection signal of the flame detection sensor 08 on the corresponding pipeline branch 03, and send the detection signal to the master controller 09. Specifically, when a fire occurs, the master controller 09 cuts off the power supply of the oil pump unit 100 where the fire occurs.

[0042] See also Figure 3In one embodiment, the pipeline branch 03 includes a main pipeline connecting section 031 and a pipeline branch section 032, the main pipeline connecting section 031 is connected to the pipeline branch section 032, the main pipeline connecting section 031 is used to fix the pipeline branch 03 on the main pipeline 02, each of the branch sub-controllers 10 is respectively arranged on the main pipeline connecting section 031 of the pipeline branch 03, the electric valve 11 of the pipeline branch 03, specifically an electric ball valve, a flame detection sensor 08 and a fire extinguishing agent nozzle 04 are arranged on the pipeline branch section 032, wherein the electric ball valve is arranged at the entrance of the pipeline branch section 032, and the electric ball valve and the flame detection sensor 08 of the pipeline branch 03 are electrically connected to the corresponding branch sub-controller 10.

[0043] See also Figure 4 , Figure 4 The circuit block diagram of the intelligent fire extinguishing device of the oil and gas gathering and transportation system in one of the embodiments shows the intelligent control working process of the intelligent fire extinguishing device of the oil and gas gathering and transportation system. After the flame detection sensor 08 on each pipeline branch 03 detects the fire information of the oil pump unit 100 below, the fire information is sent to the branch sub-controller 10 on the pipeline branch 03, and then the branch sub-controller 10 sends the fire information of each oil pump unit 100 to the main controller 09. The main controller 09 intelligently identifies the fire information of each oil pump unit 100 obtained to determine whether a fire occurs. If a fire occurs, the main controller 09 opens the electric butterfly valve of the main pipeline and issues an instruction to start fire extinguishing to the corresponding branch sub-controller 10. After receiving the instruction, the branch sub-controller 10 opens the electric ball valve of the pipeline branch 03, and the fire extinguishing agent nozzle sprays the fire extinguishing agent to the oil pump unit 100 directly below, and then performs a separate and centralized fire extinguishing treatment on the oil pump unit 100 where the fire occurs.

[0044] Specifically, each group of flame detection sensors 08 includes a smoke sensor 081, a flame sensor 082 and a temperature transmitter sensor 083. Each group of flame detection sensors 08 is arranged on a pipeline branch 03 along the fuselage direction of the oil pump unit, and is respectively connected to the branch sub-controller 10 for monitoring the fire condition of the corresponding oil pump unit 100.

[0045] Furthermore, the type of each group of flame detection sensors 08 is not limited to the above three types. After each group of flame detection sensors 08 detects the fire information of the corresponding oil pump unit, it is sent to the main controller 09 through the branch sub-controller 10. The main controller 09 can use AI technology to perform intelligent smoke recognition, intelligent flame recognition, and temperature anomaly recognition based on the acquired fire information to determine whether a fire has occurred. Once it is determined that a fire has occurred in one or more oil pump units, the main controller 09 enters the fire extinguishing program, opens the electric butterfly valve of the main pipeline 02 and the electric ball valve of the corresponding pipeline branch 03, and opens the fire extinguishing agent channel for fire extinguishing. The fire can be eliminated in the early stage of the fire, such as the high temperature period or the smoke period, before the fire has formed, effectively preventing major fires in the oil pump room and reducing the occurrence of fire accidents in the oil and gas gathering and transportation system.

[0046] In one embodiment, each pipeline branch 03 is also provided with a branch pressure transmitter 19, each branch pressure transmitter 19 is connected to the branch sub-controller 10 of the pipeline branch 03, and is used to monitor the flow of the fire extinguishing agent in the corresponding pipeline branch. If the flow of the fire extinguishing agent in the pipeline branch 03 is monitored to be too small, it means that there is too little fire extinguishing agent in the pipeline branch 03, and the information is sent to the branch sub-controller 10, and the branch sub-controller 10 can increase the flow of the fire extinguishing agent by increasing the opening of the electric ball valve of the pipeline branch to ensure the effect of fire extinguishing.

[0047] In one embodiment, the intelligent fire extinguishing device of the oil and gas gathering and transportation system also includes a base 13, the fire extinguishing agent tank body 01 is fixedly arranged on the base 13, and a pressure liquid level transmitter 14 is arranged below the fire extinguishing agent tank body 01. The pressure liquid level transmitter 14 is connected to the main controller 09 and is used to monitor the real-time liquid level of the fire extinguishing agent in the fire extinguishing agent tank body 01.

[0048] If the main controller 09 detects that the fire extinguishing agent liquid level in the fire extinguishing agent tank has dropped to a certain value, it can indicate that the fire extinguishing agent capacity in the fire extinguishing agent tank is insufficient, and remind the staff to add fire extinguishing agent to ensure that the fire extinguishing agent material is sufficient.

[0049] In one embodiment, a booster pump 15 and a main pipeline pressure transmitter 16 are also provided on the main pipeline 02. The electric valve 12 of the main pipeline 02, specifically the electric butterfly valve, the booster pump 15 and the main pipeline pressure transmitter 16 are provided in sequence and are respectively connected to the main controller 09. The booster pump 15 is used to pressurize the fire extinguishing agent output from the fire extinguishing agent tank 01, and the main pipeline pressure transmitter 16 is used to monitor the flow of the fire extinguishing agent after pressurization. When the main controller 09 detects that the flow of the fire extinguishing agent in the main pipeline is too large, the flow of the fire extinguishing agent can be reduced by reducing the opening of the electric butterfly valve of the main pipeline, so as to reasonably use the fire extinguishing agent resources without affecting the fire extinguishing effect.

[0050] In one embodiment, the intelligent fire extinguishing device of the oil and gas gathering and transportation system further includes an alarm indicator light 17, which is arranged at the end of the fire extinguishing agent tank 01 and connected to the main controller 09, and is used to light up when the main controller 09 detects a fire in the oil pump unit 100. Specifically, two red and green indicator lights can be set. When the main controller 09 detects a fire, the red light is on to remind the staff to pre-process.

[0051] In one embodiment, a vibration sensor 18 is provided on the motor of each oil pump unit 100, and the vibration sensor 18 is respectively connected to the corresponding branch sub-controller 10. When abnormal motor vibration is detected, the branch sub-controller 10 sends an abnormal signal to the main controller 09, and the main controller 09 cuts off the power supply of the corresponding oil pump unit 100, and the oil pump unit 100 stops working.

[0052] When the motor of the oil pump unit 100 vibrates abnormally, it indicates that the oil pump unit is working abnormally. The vibration sensor 18 feeds back the abnormal information to the corresponding branch sub-controller 10, and then the branch sub-controller 10 sends it to the main controller 09, which cuts off the power supply of the corresponding oil pump unit 100, thereby preventing the oil pump unit from being further damaged due to abnormal working and improving the safety performance of the oil pump unit. Among them, the abnormal vibration of the motor of the oil pump unit 100 includes abnormal working caused by fire in the oil pump unit or other abnormal working conditions.

[0053] See also Figure 5 Taking the intelligent control working process of one of the pipeline branches as an example, the smoke sensor 081, flame sensor 082 and temperature transmitter sensor 083 on the pipeline branch 03 monitor the smoke signal, flame signal and temperature signal of the oil pump unit located directly below the pipeline branch in real time, and send these fire detection signals to the branch sub-controller 10 of the pipeline branch. The branch sub-controller 10 sends these fire detection signals to the main controller 09. The main controller performs intelligent analysis on these fire detection signals to determine the fire condition of the target oil pump unit. When it is determined that the target oil pump unit is on fire, the main controller controls the main pipeline electric butterfly valve and the electric ball valve of the pipeline branch to open, and the fire extinguishing agent is sprayed from the fire extinguishing agent nozzle 04 of the pipeline branch to extinguish the fire.

[0054] The main controller 09 monitors the capacity of the fire extinguishing agent 01 in the fire extinguisher tank through the pressure level transmitter 14, and promptly reminds the staff to refill the tank to ensure sufficient supply of fire extinguishing materials. At the same time, the flow of the fire extinguishing agent in the main pipeline is monitored through the main pipeline pressure transmitter 15, and the flow is adjusted by adjusting the opening of the main pipeline electric butterfly valve. The branch sub-controller 10 monitors the flow of the fire extinguishing agent in the pipeline branch 03 through the branch pressure transmitter 19, and adjusts the flow by adjusting the opening of the pipeline branch electric ball valve, thereby controlling the flow of the fire extinguishing agent in the pipeline branch 03 within a reasonable range to ensure that the spraying force of the fire extinguishing agent at the fire extinguishing agent nozzle can achieve effective fire extinguishing.

[0055] The intelligent fire extinguishing device of the oil and gas gathering and transportation system in the embodiment of the present application realizes centralized fire management of multiple oil pump units by constructing a main pipeline and pipeline branches. The fire extinguishing agent tank uniformly provides fire extinguishing materials. By setting a main controller and pipeline branch sub-controllers, each oil pump unit can be individually monitored and extinguished. The fire monitoring is accurate and controllable, the material utilization rate is high, and the response speed is fast. The oil pump can be quickly and effectively extinguished in the early stage of the fire, effectively preventing the occurrence of fires in the oil and gas gathering and transportation system.

[0056] See also Figure 5 The embodiment of the present application also proposes an intelligent fire extinguishing system for an oil and gas gathering and transportation system, comprising the intelligent fire extinguishing device for the oil and gas gathering and transportation system described in any of the above embodiments, and a monitoring terminal 20, wherein the monitoring terminal 20 is connected to the controller, specifically the main controller 09, receives the fire information of each oil pump unit 100 sent by the main controller 09, and arranges and displays the fire information.

[0057] Specifically, the monitoring terminal 20 can be a monitoring platform, a personal computer of a monitoring person, a mobile terminal, or other monitoring equipment. The fire information of each group of oil pump units 100 is arranged and displayed on the monitoring terminal 20, so that the fire detection information of each oil pump unit 100 in each group of oil pump units in the oil and gas gathering and transportation system can be viewed intuitively, abnormal conditions can be discovered in time, and the occurrence of fire can be reduced.

[0058] Furthermore, the monitoring terminal 20 is also provided with a control menu, and the monitoring personnel can remotely and manually control each oil pump unit by operating the control menu. When the monitoring personnel need manual intervention, they can issue relevant instructions to the main controller by operating the control menu on the monitoring terminal interface to control the fire management process.

[0059] In one embodiment, the monitoring terminal 20 includes a display 21 and a manual control keyboard 22, and the monitoring personnel can also intervene in the fire management process by inputting control instructions through the manual control keyboard.

[0060] Furthermore, the monitoring terminal 20 is also provided with an audible and visual alarm 23. When the main controller 09 detects a fire, the monitoring terminal 20 receives the fire information sent by the main controller 09 via a data line or wireless transmission, and wakes up the audible and visual alarm to remind the monitoring personnel to pay attention and handle it in time, thereby further ensuring that the fire is handled promptly and effectively.
