A kind of elevated torch system step emission device.
Background technology
It is important that the discharge of petrochemical enterprise imflammable gas and recovery system are to ensure that process unit is kept the safety in production
Measure and environmental protection and energy saving measure, due to the difference of discharge back pressure of the imflammable gas of process unit discharge, lead to
Multiple exhaust system, i.e. high pressure, low pressure and low low-pressure system often can be set.General high voltage, low pressure, low
Press do-nothing system through the separatory tank of respective supporting setting and water sealed tank, enter overhead torch after-combustion emptying.
Along with the maximization of petrochemical enterprise develops, scale and the emptying amount of process unit are increasing, enter
And the scale of the torch facility that factory is supporting quantity the most increasing, flare tip gets more and more entirely, the fire of configuration
Torch head diameter reaches more than DN1000, even reaches DN2000.One is if multiple emptying gas is all separately provided
Independent blowdown system, necessarily causes the quantity of flare tip to increase, and size heterogeneity is relatively big, not only increases
Investment, and operation and maintenance management difficulty is bigger, it is impossible to realize the on-bne repair of any one flare tip；
Two is that heavy caliber flare tip is susceptible to smoldering phenomenon when process unit low discharge discharge imflammable gas,
Not only reduce the service life of flare tip, and there is security risk；Three is that multiple emptying gas the most individually sets
Put independent blowdown system, the operating mode of multiple flare tip Smaller load burning simultaneously will necessarily occur, not only waste
Resource, uneconomical energy-conservation, decrease the service life of flare tip, and there is potential safety hazard, cannot realize
On-bne repair flare tip.
Utility model content
Short in order to solve the service life of the flare tip that prior art exists, there is potential safety hazard, it is impossible to realize
The first-class shortcoming of on-bne repair torch, this utility model provides a kind of elevated torch system step emission device.
The elevated torch system step emission device that this utility model provides mainly is converged by separatory tank, emptying gas
Pipe, stop valve, water sealed tank and overhead torch composition；Emptying gas header closed at both ends, parallel on its tube wall
It is provided with one, two or many emptying gas ingress pipes and two or many emptying gas delivery lines；Put for every
Each independent with one the separatory tank of air body ingress pipe connects, and each independent separatory tank is the most each connected to
Emptying gas conveying pipe；Each independent with one water sealed tank of every emptying gas delivery line connects, Mei Geshui
Sealed cans each connect with an overhead torch again, and every emptying gas delivery line is each provided with a stop valve；
Emptying gas conveying pipe, separatory tank, emptying gas ingress pipe, emptying gas header, emptying gas delivery line,
Stop valve, water sealed tank and overhead torch are sequentially communicated, and constitute emptying gas passage.
Described emptying gas header diameter determines according to flare vent system drop requirements, and its pipe section amasss
Preferably equal to or greater than each emptying gas ingress pipe pipe section amasss sum.
Described water sealed tank each has different water seal heights, and effective water seal height is preferably 400～1200mm,
To play the purpose of grading control emptying gas discharge.
This utility model compared with prior art, has the advantage that
(1) using step emission technology, optimize the configuration of flare system, concise in technology, at multiply high pressure
Emptying gas, lp venting gas are respectively by arranging emptying gas header, so after exhausting pipeline and separatory tank
The most automatically each is entered break through the water seal of corresponding water sealed tank afterwards according to the build pressure height of emptying gas after high
It is vented after frame torch burning, not only prevent flare tip smoldering and the Smaller load burning simultaneously of multiple flare tip, peace
Complete reliable, energy efficient, especially can reduce scale and the investment of large enterprise's torch facility, have certain
Safety, advance and economy；
(2) stop valve is set on the emptying gas delivery line connected with every water sealed tank, any one can be realized
The on-bne repair of individual flare tip and maintenance, add motility and safety that torch runs, for process unit
Even running provide guarantee.

No. two lp venting gas passages being sequentially communicated composition enter emptying gas header 9.
B) starting to be vented the stage at process unit, in emptying gas header 9, emptying gas pressure gradually rises,
When rising to 6KPa (G), enter one-level overhead torch 13 after breaking through the water seal of one-level water sealed tank 10 and process；
Along with being gradually increased of emptying amount, in emptying gas header 9, emptying gas pressure also gradually rises, and works as emptying
When amount reaches the disposal ability of one-level overhead torch 10, in emptying gas header 9, emptying gas pressure rises to
8KPa (G), now emptying gas will break through the water seal of two grades of water sealed tanks 11, and a part of emptying gas enters two
Level overhead torch 14 processes；The rest may be inferred.
C) terminating the emptying stage at process unit, in emptying gas header 9, emptying gas pressure is gradually lowered,
When being down to 10KPa (G), emptying gas cannot break through the water seal of tertiary effluent sealed cans 12, corresponding three grades overhead
Torch 15 automatic distinguishing；Along with being gradually reduced of emptying amount, in emptying gas header 9, emptying gas pressure is also
Being gradually lowered, when in emptying gas header 9, emptying gas pressure is down to 8KPa (G), emptying gas cannot
Break through the water seal of two grades of water sealed tanks 11, corresponding two grades of overhead torch 14 automatic distinguishings；The rest may be inferred.
D) when any of which one-level overhead torch head breaks down, it is only necessary to cut off corresponding stop valve, and
After pipeline after stop valve, torch cylinder, flare tip are carried out nitrogen purging, just can realize overhead torch head
Dismantle online, overhaul, safeguard and install.
