[0006] On the other hand, the floating roof of the storage tank will rise and fall with the liquid level of the storage tank. Excessive load-bearing of the floating roof will cause the risk of the floating roof sinking. Therefore, after the active protection system is installed, it must not affect the normal operation of the storage tank, and there must be lightning protection Shock, anti-static measures

The invention discloses a mounting method of an external floating roof oil tank active protection system. The system comprises a micro fog sprayer and a sampling probe arranged in a first sealing ring and a second sealing ring of the external floating roof oil tank, wherein the micro fog sprayer and the sampling probe are connected with a field device arranged outside a fire dike of the oil tank through a pipe network. Through the pipe network structure design and mounting method of communicating the field device with the micro fog sprayer, and connecting the field device with the sampling probe, the system can be mounted under the condition that the oil tank has oil; the lifting requirements of the oil tank along with the liquid level can be satisfied; the load of the oil tank floating roof is not affected by the added materials; through the design of a hose, the static electricity generated when the liquid flows can be eliminated; and the lightning protection and grounding diversion ability of the oil tank can be strengthened.
Description
technical field [0001] The invention belongs to the technical field of fire safety, and in particular relates to an installation structure of an active protection system for an external floating roof oil storage tank. Background technique [0002] Oil storage tanks with external floating roofs have become the main facilities for storing crude oil on the ground in various countries due to their advantages of low oil loss, environmental protection, and space saving. The large-scale oil storage tanks have brought great challenges to oil storage and transportation. In recent years, there has been a high incidence of fire accidents in oil storage tanks with external floating roofs, causing heavy casualties and property losses, as well as large-scale environmental pollution. [0003] Sealing ring fire is the most important form of fire in external floating roof storage tanks. Nowadays, almost all petrochemical companies use foam fire extinguishing systems to protect oil storage t...
