Description
Technical field
The invention belongs to gas distributions and storage engineering field, are related to a kind of superfluous coal gas automatic combustion diffusion system.
Background technique
Gas chamber is a kind of jumbo for storing low-pressure gas, it can balance the production and marketing fluctuation of coal gas, plays energy-saving ring
The effect of guarantor is gas distribution, storage and the important equipment using field, especially in coal resources such as integrated iron and steel works
Under the huge service condition of consumption, the dry gas holder that stable gas pressure is generated using piston own wt is obtained
It is widely applied, this gas chamber is stablizing gaspipe network pressure, in terms of stablizing the thermal regulation of user and improving product quality
It is of great advantage.
By taking the blast furnace coal gas holder of integrated iron and steel works as an example, since blast furnace gas volume of production and marketing is huge and hot-blast stove periodically changes
The reasons such as furnace (about 50min/ times) cause full factory's pipe network blast furnace gas production and marketing fluctuation larger, and gas chamber is only capable of undertaking blast funnace hot blast stove
The short-term unbalanced problem such as furnace is changed, the pressure oscillation that gas chamber piston rise and fall balance coal gas production and marketing fluctuation generates generally exists
Within ± 300Pa, the gas balance of long period is by blast furnace gas interruptible customer (power plant etc.) and superfluous gas-fired diffusing tower
(burning release) is realized.Blast furnace coal gas holder belongs to a kind of huge field device of low pressure, generally by the design and work order of profession
Position is built, and cabinet holds (coal gas storage capacity) and is usually set to the chain of coal gas exits and entrances valve：When piston rises to H (about
The 90% of effective cabinet appearance) when, alarm signal is issued, reminds dispatcher that Operation Measures is taken to reduce depth pistion and (reduces coal gas
Storage capacity), when piston rises to HH (the 95% of about effective cabinet appearance), alarms and coal gas exits and entrances valve is automatically closed；When
When piston rises to the position HHH (about 97%) that effective cabinet holds, gas safety release tube valve emission coal gas is automatically opened to prevent
Piston, which continues to rise, causes gas chamber emergency diffusion coal gas, and when piston continues to rise, gas chamber is by automatic emergency emission coal gas
Prevent piston from rushing to summit；When piston drops to L (the 10% of about effective cabinet appearance), alarm signal is issued, dispatcher is reminded to adopt
Operation Measures lifting up piston height (increasing coal gas storage capacity) is taken, when piston drops to LL (the 5% of about effective cabinet appearance), report
Coal gas exits and entrances valve is warned and be automatically closed, is caused the accident with preventing piston from hitting bottom.Cabinet holds (coal gas storage capacity) signal and send the energy
The signal that center or gas dispatching room are monitored as operator.
Existing literature《The design of system of blast furnace gas automatic spread》Integrated iron and steel works' blast furnace gas is illustrated to put automatically
Dissipate the working principle of system (i.e. blast furnace gas combustion diffusing tower)：When gas main ductwork pressure is higher than setting value (such as 9310Pa)
When, system starts automatic relief coal gas, and blast-furnace gas pressure is maintained at a certain value；Igniter is opened simultaneously, ignites and puts
Coal gas in separate tube closes ignition system after 3~5min.When the gas pressure of general pipeline pipe network is lower than setting value (such as 8820Pa)
When, system is automatically stopped release, opens simultaneously steam smoothering and scavenging, is automatically closed after 3~5min, reaches stable blast furnace pipe network
The purpose of gas pressure.
As it can be seen that, since the pressure stabilization function of blast furnace coal gas holder is good, superfluous blast furnace gas is automatic when full factory's pipe network gas excess
The ductwork pressure that diffusion system detects is not high will not generally to be acted, and the piston of blast furnace coal gas holder will continue to rise at this time, blast furnace
Blast furnace coal gas holder coal gas exits and entrances valve is closed when gas chamber piston reaches the 95% of cabinet appearance, and blast furnace coal gas holder is forced to be transported offline
Row, at this time superfluous blast furnace gas Shi Quan factory pipe network gas pressure raising cause system of blast furnace gas automatic spread to start automatically,
To guarantee the safety of pipe network.The above-mentioned prior art has the following problems：When blast furnace coal gas holder is because of originals such as coal gas terminal valve failures
The chain closing exits and entrances valve failure of the effective cabinet of blast furnace coal gas holder holds because caused by 95%, piston continue to rise, and gas chamber will
Pass through safe desorption tube even emergency diffusion pipe emission coal gas (not combustion system)；Or blast furnace coal gas holder cabinet appearance is high-order chain
After closing coal gas terminal valve, piston scheduling operation personnel do not take measures to reduce depth pistion once neglecting, since the sun shines
Warm lifting up piston of emanating, which continues to rise, causes gas chamber emergency diffusion (not combustion system) etc. that coal gas is caused not burn release, all
The problem of will cause environmental pollution even gas chamber personnel's poisoning nearby.
Summary of the invention
In view of this, it is an object of the invention to by the gas chamber and superfluous gas-fired diffusing tower in full factory's coal gas system
It considers as a whole, provide one kind is by what the superfluous coal gas in gas pipe net system and gas chamber carried out automatic combustion release as far as possible
