Description
Technical field
It meets an urgent need emptying technical field of combustion equipment the present invention relates to day hot gas, and in particular to a kind of Liftable type is released flare
System.
Background technique
Release flare be for handle petrochemical plant, oil plant, chemical plant and other factories or device can not recycle and
The fuel gas of reprocessing and the special combustion plant of steam, be guarantee factory safety production, important setting of reducing environmental pollution
It is standby.Releasing flare is the facility of each natural gas station indispensability.Some pressure vessels, valve or metering pressure regulation in station are set
It is standby that first step when detachable maintaining is needed to carry out the emptying of local pipeline section certainly, that is, the equipment that needs are safeguarded is upper
Valve downstream is closed, and emptying natural gas, regular way is to continue with injection nitrogen, and remaining natural gas is emptied, these are natural
Gas nitrogen is all from releasing flare away.Main points are burnt when natural gas vent in principle, become water and carbon dioxide,
It because methane is although nontoxic, but is more many times higher than carbon dioxide to the greenhouse effects of atmosphere.
It releases flare and is generally located in place of spacious field, height is generally at 20 meters or more, although there is ladder scaffolding,
It is that task difficulty of ascending a height is larger, main cause is that caliber of releasing flare is smaller, and is unfavorable for operation of ascending a height in head ladder arrangement
Person.It releases flare and is placed in field for a long time, corrosion phenomenon is serious, causes operation obstacle to the operator that ascends a height.Live generally use is taken
Frame maintenance, heavy workload is time-consuming, and safe condition is poor, constitutes a threat to safely to the life of operating personnel.
In addition, sparking mode in the prior art of releasing flare is single, it is typically only capable to manual ignition, does not have automatic ignition
Function, can not judge automatically igniting it is whether normal, do not have the automatic priority function that stops working yet, behave inconvenience.And it lights a fire
Device is located at high-altitude, high temperature, in high corrosion environment for a long time, in case of igniter is damaged, it is necessary to enter high-risk ring by operation maintenance personnel
Border carries out maintenance replacement, and there are very big security risks for this process.
Summary of the invention
The present invention is intended to provide a kind of Liftable type Venting and Flare Stack System, changes in the prior art release flare
