Description
Technical Field
[0001] This utility model relates to the field of fire extinguishing, and in particular to a waterless fire extinguishing agent storage device and an oil and gas gathering and transportation fire extinguishing system. Background Technology
[0002] In the field of fire protection, extinguishing agent storage equipment is a crucial component for ensuring emergency fire response capabilities. Traditional extinguishing agent storage equipment often employs a water-inlet replenishment mechanism, which involves injecting water into the tank to dilute or activate the extinguishing agent. While this method can meet firefighting needs to some extent, it also has inherent limitations and shortcomings. For example, water-inlet equipment requires an external water source to replenish the extinguishing agent, which not only increases the complexity of the equipment and maintenance costs but may also affect the performance and stability of the extinguishing agent due to water quality issues.
[0003] To address these issues, the industry has recently begun exploring the design and development of waterless fire extinguishing agent storage devices. These devices enable the effective storage and flexible replenishment of foam fire extinguishing agents without relying on an external water source. However, existing waterless fire extinguishing agent storage devices still have design shortcomings. They cannot monitor and control the real-time pressure of the foam fire extinguishing agent inside the tank, and the storage tanks often crack and break due to excessive internal pressure. This prevents the equipment from operating safely for extended periods under high pressure, thus affecting fire safety. Utility Model Content
[0004] The main purpose of this utility model is to provide a waterless fire extinguishing agent storage device and an oil and gas gathering and transportation fire extinguishing system, which aims to solve the technical problem of not being able to monitor and control the real-time pressure of the foam fire extinguishing agent in the tank.
[0005] To achieve the above objectives, this utility model provides a waterless fire extinguishing agent storage device, comprising: a foam tank for storing fire extinguishing agent, wherein the top of the foam tank is provided with a water inlet and vent for replenishing fire extinguishing agent, and the bottom of the foam tank is provided with a first pressure sensor for detecting the real-time water pressure of the internal fire extinguishing agent; an output pipe connected to the foam tank for conveying the fire extinguishing agent after foam generation to the fire extinguishing equipment; and a discharge pipe, one end of which is connected to the bottom of the foam tank and the other end of which is connected to an external waste liquid treatment device, wherein the discharge pipe is provided with a pressure relief valve, which opens to discharge excess fire extinguishing agent to balance the internal pressure after the first pressure sensor detects that the internal pressure of the foam tank exceeds a preset value.
[0006] Preferably, the foam tank is provided with a liquid storage tank at the bottom, one side of the liquid storage tank is connected to the output pipe, and the bottom of the liquid storage tank is connected to the discharge pipe.
[0007] Preferably, the output pipe is equipped with an electric valve, which is used to control the on / off state of the output pipe.
[0008] Preferably, the output tube is equipped with a second pressure sensor, which is used to detect the real-time pressure inside the output tube, and the second pressure sensor is electrically connected to the electric valve.
[0009] Preferably, the output pipe is equipped with a booster pump, which is used to increase the delivery speed of the extinguishing agent from the storage tank.
[0010] Preferably, a foam venting valve is provided near the liquid storage tank in the output pipe. The foam venting valve is used to close the output of the liquid storage tank and vent the fire extinguishing agent foam in the output pipe.
[0011] Preferably, it also includes a water level gauge for viewing the internal water level, one end of which is connected to the top of the inside of the foam tank and the other end is connected to the bottom of the inside of the foam tank.
[0012] Preferably, it also includes a base, and the bottom of the foam tank is provided with a bracket, which is fixedly mounted on the base. The height of the bracket is greater than the length of the liquid storage tank. The top end of the discharge pipe is connected to the liquid storage tank, and the bottom outlet of the discharge pipe passes through the base.
[0013] Preferably, the base is provided with a plurality of support seats, which are used to support and fix the output tube.
[0014] This utility model also provides an oil and gas gathering and transportation fire extinguishing system, including a control terminal, a fire extinguishing device, and the aforementioned water-inlet mixed fire extinguishing agent storage device. The fire extinguishing device includes a main pipeline and several spray branches connected to the main pipeline. The main pipeline is connected to the output pipe. Each spray branch is equipped with a branch switch valve for controlling the on / off state of the spray branch and at least one nozzle for spraying fire extinguishing agent. The control terminal is used to identify the fire situation and control the on / off state of the branch switch valve to start or stop the nozzle from spraying fire extinguishing agent.
[0015] In the technical solution provided by this utility model, the first pressure sensor integrated in the equipment can monitor the extinguishing agent water pressure inside the foam tank in real time. When the pressure exceeds the preset value, the pressure relief drain valve can be opened manually or electrically to discharge excess extinguishing agent to balance the internal pressure, effectively preventing equipment damage or safety hazards caused by overpressure. When it is necessary to replenish the extinguishing agent, it can be replenished without pressure through the water inlet and vent outlet, avoiding the pressure fluctuations that may occur during the replenishment process of traditional water-inlet equipment. At the same time, when it is necessary to discharge excess extinguishing agent, the pressure relief drain valve can quickly respond and discharge the specified amount of extinguishing agent, ensuring the stable operation of the equipment and the effective utilization of the extinguishing agent.
