Laser passive distributed type active safety protection system for oil storage tank

Abstract

The invention discloses a laser passive distributed type active safety protection system for an oil storage tank, and relates to the technical field of oil and gas detection of oil storage tanks. Thelaser passive distributed type active safety protection system for the oil storage tank comprises a first sealing plate, a second sealing plate, a central processing system, a first steel plate, a bottom plate and a second steel plate, wherein one side of the first sealing plate and one side of the second sealing plate are fixedly connected with a wall body, the top of the first steel plate is fixedly connected with a totally enclosed passive probe, and an oil gas inlet, and a nitrogen injection opening and an air extraction opening are separately formed in one side of the totally enclosed passive probe; one side of the second steel plate is fixedly connected with a filter device, and one side of the filter device communicates with a guide pipe, and the end, away from the filter device, ofthe guide pipe penetrates through the first sealing plate and extends to the other side of the first sealing plate. The laser passive distributed type active safety protection system for the oil storage tank can achieve nondestructive detection of gas, is convenient to maintain, only needs to periodically replace the filter device, has no pollution in tail gas recovery, and greatly improves the working efficiency.

Description

Technical field [0001] The invention relates to the technical field of oil and gas detection of oil storage tanks, in particular to a laser passive distributed active safety protection system for oil storage tanks. Background technique [0002] Oil storage tank is a container for storing oil products. The main facility of an oil depot is the oil source interface of the oil pipeline in pipeline transportation. According to the construction characteristics, it can be divided into aboveground oil tanks, underground oil tanks and cave oil tanks, transfer oil depots and distribution Oil depots and enterprise-affiliated oil depots generally should choose above-ground oil tanks, while reserve oil depots and military oil depots of strategic significance often use cavern oil tanks, underground oil tanks and semi-underground oil tanks, which can be divided into non-metal oil tanks and metal oil tanks according to their materials. Two categories, non-metal oil tanks include reinforced concr...
