Description

Technical Field

[0001] The present invention belongs to the technical field of fire safety control of oil pump rooms, and in particular relates to a fire safety control system and method for oil pump rooms. Background Art

[0002] In the prior art, the final assembly workshop of an automobile factory is the last workshop to produce finished automobiles. After the vehicle is assembled, it needs to be refueled before it can be started and rolled off the production line. The oil tanks for storing fuel are generally set up far away from the workshop and other buildings. In order to achieve long-distance fuel transportation, an oil pump room is required to provide power for fuel transportation; there are a large number of flange connection interfaces in the oil pipeline in the oil pump room, and the risk of oil and gas leakage is relatively high. In addition, the oil pump room is a closed space with a large fire and explosion safety risk. The following measures are taken in the prior art: 1. In order to reduce the oil and gas concentration in the oil pump room, manual ventilation is often used to open the exhaust fan; 2. In order to deal with fire accidents, portable fire extinguishers or cart-type fire extinguishers are placed at the door of the oil pump room. When a fire accident occurs, the management personnel will go to the oil pump room after receiving the fire alarm and use the portable fire extinguisher placed at the door of the pump room to extinguish the fire. This leads to the following disadvantages: 1. Low operating efficiency and high energy consumption. The exhaust fan needs to be manually opened and closed for daily ventilation in the pump room. After the fan is started, it cannot be automatically opened and closed according to the concentration of combustible gas on site. It needs to run for a long time, resulting in energy waste; 2. Poor timeliness. When a fire accident occurs, the management personnel will go to the pump room to use portable fire extinguishers to extinguish the fire after receiving the fire alarm remotely, which requires a certain amount of accompanying operation time. It is impossible to take timely and effective fire extinguishing measures in the early stage of the fire; 3. Low safety. When a fire occurs, the on-site management personnel manually extinguish the fire, and the smoke and high temperature on site can easily cause casualties.

[0017] Figure 1 is a schematic diagram of a fire safety control system for an oil pump room in some embodiments of the present invention; Figure 2 It is a flow chart of the fire safety control method for oil pump room of the present invention; DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] like Figure 1 As shown, the present invention discloses a fire safety control system for an oil pump room, comprising: Detectors, used to monitor the oil pump room and obtain monitoring data; The combustible gas alarm system 3 is used to obtain monitoring data and determine whether the combustible gas concentration value in the oil pump room exceeds the set value according to the monitoring data. If it exceeds the set value, an alarm is issued and the alarm information is sent to the control cabinet 5; The fire detection alarm system 4 is used to obtain monitoring data, and determine whether the monitoring value in the oil pump room exceeds the set value according to the monitoring data. If it exceeds the set value, an alarm is issued and the alarm information is sent to the control cabinet 5; Control cabinet 5, used to obtain the alarm information of the combustible gas alarm system and the fire detection alarm system, and send relevant control instructions to the oil supply pipeline switching system, the ventilation control system, and the fire extinguishing control system according to the alarm information; The oil supply pipeline switching system 6 is used to obtain control instructions and control the action of the oil supply pipeline solenoid valve 16; The ventilation control system 7 is used to obtain control instructions and control the operation of the ventilation device; The fire extinguishing control system 8 is used to obtain control instructions and control the action of the fire extinguishing device 15; Among them, the detectors include: combustible gas detector 9, smoke detector 10, temperature detector 11, flame detector 12; combustible gas detector 9, smoke detector 10, temperature detector 11, flame detector 12, oil supply pipeline solenoid valve 16, ventilation device, fire extinguishing device 15 can be set at any position in the oil pump room as needed, and control cabinet 5, combustible gas alarm system 3, fire detection alarm system 4, oil supply pipeline switching system 6, ventilation control system 7, fire extinguishing control system 8 can be set at any position in another equipment room as needed. The output end of the combustible gas detector 9 is connected to the input end of the combustible gas alarm system 3, and the output end of the smoke detector 10, the output end of the temperature detector 11, and the output end of the flame detector 12 are connected to the input end of the fire detection alarm system 4. The output end of the combustible gas alarm system 3 and the output end of the fire detection alarm system 4 are connected to the control cabinet 5; the control cabinet 5 is connected to the oil supply pipeline switching system 6, the ventilation control system 7, and the fire extinguishing control system 8.

[0020] The flame detector 12 is a red-ultraviolet composite flame detector, which combines ultraviolet (UV) and infrared (IR) technologies and can effectively detect flames at different stages of flame combustion. When the flame just starts to burn, a large amount of ultraviolet light will be released, and the red-ultraviolet composite detector can sensitively identify these ultraviolet light signals to ensure the rapid discovery of the fire. As the flame continues to burn, the infrared light will be more sufficient than the ultraviolet light, and the infrared detector can effectively receive this part of the signal. Therefore, this composite detector can detect the presence of flames earlier, improving the timeliness and effectiveness of the early warning.

[0021] The ventilation device includes: an exhaust fan 14 and a supply fan 13, specifically a BFAG-500 explosion-proof fan. In actual application, it can be used as an exhaust fan or a supply fan according to the difference in installation direction. The BFAG-500 explosion-proof fan is an explosion-proof axial flow fan with a large explosion-proof air volume and low operating noise. It is suitable for use in hazardous environments and improves the safety factor of the oil pump room.

[0022] The fire extinguishing device 15 adopts a dry powder fire extinguisher, specifically a FZX type suspended ultra-fine dry powder fire extinguisher. The FZXA8 suspended ultra-fine dry powder fire extinguisher has high efficiency in fire extinguishing, simple installation, flexible starting method, economic cost-effectiveness, environmentally friendly performance and a wide range of application scenarios. It can extinguish the fire source more quickly, and the fire extinguishing effect is faster and more efficient. It is suitable for fighting large-scale and complex fires, and further improves the safety factor of the oil pump room.

[0023] There are mainly two situations in the working process: 1. Under normal circumstances, that is, the oil pump room 1 can ensure normal automatic daily ventilation, the combustible gas alarm system 3 reads the monitoring data of the combustible gas detector 9, and judges whether the combustible gas concentration value in the oil pump room exceeds the set value according to the monitoring data. After exceeding the set value, an alarm is issued and the alarm information is sent to the control cabinet 5. The control cabinet 5 processes the alarm information according to the alarm information sent by the combustible gas alarm system 3, sends a control instruction to the ventilation control system, and the ventilation control system controls the action of the ventilation device to ventilate the factory building on a daily basis. After the ventilation time reaches the set time, the ventilation is stopped. When the combustible gas concentration in the oil pump room 1 meets the standard, the ventilation device can be automatically opened and closed by issuing a control instruction through the control cabinet, without manual opening. After the exhaust is completed, the ventilation device is automatically closed, avoiding the long-term inefficient operation of the fan and saving energy. 2. In the case of fire, the fire detection alarm system 4 reads the monitoring data of the smoke detector 10, the temperature detector 11, and the flame detector 12, and judges whether the monitoring value in the oil pump room exceeds the set value according to the monitoring data. After exceeding the set value, an alarm is issued and the alarm information is sent to the control cabinet. The control cabinet processes the alarm information according to the alarm information sent by the fire detection alarm system, and sends control instructions to the oil supply pipeline switching system 6, the ventilation control system 7, and the fire extinguishing control system 8. The ventilation control system 7 controls the operation of the ventilation device to stop the ventilation device from working; the oil supply pipeline switching system 6 controls the operation of the oil supply pipeline solenoid valve 16 to shut down the power source of the oil pump, prevent air from entering, and automatically cut off the oil supply to prevent the fire from developing further. The fire extinguishing control system 8 controls the operation of the fire extinguishing device 15 to work and extinguish the fire at the fire point, thereby controlling the fire, reducing the accident rate, improving the safety factor of the oil pump room, and realizing the automatic fire protection of the oil pump room.

[0024] In actual application, the detector can also be replaced by a sensor with equivalent functions, which can also realize fire safety control of the oil pump room. The specific sensors will not be described here.
