Abstract
The invention discloses an oil gas collecting device of a crude-oil outward floating roof tank. The oil gas collecting device comprises sealing cord fabric. The sealing cord fabric is connected between a tank roof and a floating disc, a tank-roof pressing strip plate is arranged on the tank roof, a floating-disc pressing strip plate is arranged on the floating disc, the upper edge of the sealing cord fabric is connected with the tank-roof pressing strip plate, and the lower edge of the sealing cord fabric is connected with the floating-disc pressing strip plate; and sealed oil gas collecting space is formed among the sealing cord fabric, the tank wall and the floating disc and connected with an oil gas recycling system through an oil gas recycling pipe, and breather valves are arranged on the tank-roof pressing strip plate. According to the oil gas collecting device, as the sealing cord fabric is arranged between the tank roof and the floating disc, the contact between oil products and air can be completely isolated, all volatilized gas is entirely delivered to the oil gas recycling system in a sealed manner, overflowed oil gas can be prevented from being directly discharged to atmosphere, and the environment is protected; and as no oil gas overflows, the danger level of the surface space of the floating disc is reduced, and the safety level of the oil tank is improved.
Description
Technical field
The present invention relates to a kind of crude oil External floating roof tank, specifically relate to a kind of crude oil External floating roof tank oil gas collecting device.
Background technology
Crude oil External floating roof tank does not have top cover, and floating plate is directly exposed in air, generally adopts hermetically-sealed construction between floating plate and oil tank wall, prevents the oil product volatilization stored.Because poorly sealed and oil and gas leakage that is that cause often can occur External floating roof tank.At thunderstorm season, easily there is the seal ring fire accident caused of being struck by lightning in storage tank.The oil gas of tank leakage is generally the light component in crude oil, leaks not only contaminated environment in a large number, and affects the yield of light oil in oil refining process.Rich hydrogen sulfide containing oil gas also may cause tank operation personnel that poisoning personal injury accident of Denging occurs.Therefore the oil gas of centralized collection crude oil storage tank seal leakage, and recycled, be not only conducive to environmental protection, be more conducive to safety.
External floating roof tank top uncovered, uncovered, the frequent up-and-down movement of floating plate, sealing and tank skin relative motion, be difficult to form actv. enclosure space, causes to leak oil gas and be difficult to collect, and available data does not see relevant report.
Summary of the invention
Based on above-mentioned technical matters, the invention provides a kind of crude oil External floating roof tank oil gas collecting device.
The technology used in the present invention solution is:
A kind of crude oil External floating roof tank oil gas collecting device, comprise sealing cord, sealing cord is connected between storage tank tank deck and floating plate, storage tank tank deck is provided with tank deck press strip plate, floating plate is provided with floating plate press strip plate, the upper edge of sealing cord is connected with tank deck press strip plate, the lower edge of sealing cord is connected with floating plate press strip plate, sealing cord and storage tank shell, form airtight oil gas collection space between floating plate, airtight oil gas collection space connects gas recovery system for oil by petroleum vapor recovery pipe, and tank deck press strip plate is provided with breathing valve.
Preferably, described sealing cord is made up of government rubber, and thickness is between 1.0-2.5mm.
Preferably, described tank deck press strip plate is made up of stainless steel material, and ringwise, tank deck press strip plate level is welded on inside Tank top edge.
Preferably, described breathing valve arranges 3 altogether, and uniform on tank deck press strip plate.
Preferably, the edge of described floating plate and the below of tank deck press strip plate are provided with cord baffle plate.
Preferably, between described sealing cord and tank deck press strip plate, seal between cord and floating plate press strip plate all with bolts.
Preferably, strengthening rib is provided with between described tank deck press strip plate and storage tank shell.
Advantageous Effects of the present invention is:
The present invention arranges sealing cord between storage tank tank deck and floating plate; the contact of oil product and air can be closed completely; the whole closed conveying of gas of all volatilizations is to gas recovery system for oil; avoid overflowing oil gas directly to airborne release; protection of the environment; and owing to not having oil gas to overflow, floating plate space surface hazard level declines, and improves the security level of oil tank.The oil gas reclaimed can also create larger value.
