Problems solved by technology

[0003] Due to the late start in our country, there are not many large crude oil storage tanks with tens of thousands of tons. After nearly two years of development, our country’s current volume is 100,000 m 3 There are hundreds of crude oil storage tanks above, with a volume of 150,000 m 3 There are also more than 10 large floating roof storage tanks with large storage capacity and high potential danger. In the event of a fire accident, the loss will be very heavy

Embodiment 1

[0057] The 50,000 m standard floating roof oil storage tank is 19.5m high, 60m in diameter, and 188.4m in circumference. In this example, a fiber grating automatic fire detection and alarm system is set up. The fiber grating temperature sensing fire detection signal processor is placed in the monitoring station, and the signal processor and the fiber grating temperature sensor are connected by a 24-core armored optical cable. The fiber grating temperature-sensitive fire detector is installed on the outer edge of the secondary sealing ring of the floating plate on the top of the tank along with the detection optical cable, and the distance is about 6.0m. Two sensor chains are used on the top floating plate of the oil tank, and each sensor chain contains 16 fiber grating temperature sensors. The laying section of the optical cable in the tank is protected by a metal hose with a diameter of DN40 from the top of the tank to the floating plate in the tank. The upper end of the meta...

Embodiment 2

[0062] The 100,000 m standard floating roof oil storage tank is 21.8m high, 80m in diameter, and 251.2m in circumference. In this example, a fiber grating automatic fire detection and alarm system is installed. The fiber grating temperature sensing fire detection signal processor is placed in the monitoring station, and the signal processor and the fiber grating temperature sensor are connected by a 24-core armored optical cable. The fiber grating temperature-sensitive fire detector is installed on the top of the tank along with the detection optical cable, and the outer edge of the secondary sealing ring, with a distance of about 6.0m. Three sensor chains are used on the oil tank filling floating plate, and each sensor chain contains 15 fiber grating temperature sensors. The laying section of the optical cable in the tank is protected by a metal hose with a diameter of DN40 from the top of the tank to the floating plate in the tank. The upper end of the metal hose is fixed on...

Abstract

The invention discloses a cold aerosol fire-extinguishing method for a large floating roof storage tank. The cold aerosol fire-extinguishing method comprises the following steps of: dividing a top surface of a floating disc into fire-extinguishing unit modules, wherein a fire-extinguishing unit module is divided along a floating disc sealing ring every 60m or less and all the fire-extinguishing unit modules on the top surface of the floating disc form a fire-extinguishing partition; arranging a fiber grating automatic fire detection alarm and a fiber grating signal processor; arranging a cold aerosol fire-extinguishing agent generating device; installing a cold aerosol fire-extinguishing agent spraying pipeline; transmitting detection data back to the fiber grating signal processor; after recognizing, judging and confirming, starting a fire-extinguishing device and releasing a cold aerosol fire-extinguishing agent, wherein the cold aerosol fire-extinguishing agent is sprayed into a sealed space formed by primary sealing and secondary sealing through a special spraying pipeline so as to extinguish fire. Alarm equipment, the fire-extinguishing device and installed accessories and auxiliary materials have temperature-resistant, waterproof, corrosion-resistant, mechanical protection functions and the like; a harsh environment and explosion-proof requirements of an oil tank can be met; and the volume is small, the weight is light, the using amount is small, and the protection range is wide.

Description

technical field [0001] The invention belongs to the technical field of fire fighting, and in particular relates to a cold aerosol fire extinguishing method for a large floating roof oil storage tank. It is suitable for use in large and super large floating roof oil storage tanks. Background technique [0002] Against the background of the energy crisis, as the largest developing country in the world, China is a big energy consumer. Basic energy consumption accounts for 1 / 10 of the world's total consumption, second only to the United States, ranking second in the world. With the development of my country's petrochemical industry and the implementation of the National Crude Oil Strategic Reserve Project, the enlargement of oil tanks will become an inevitable trend of development. The safe storage capacity of foreign crude oil is 90 days, and the longest can reach 150 days, while my country's current storage capacity is only 15 days, and the country's short-term goal is to re...
