Description
Technical field
The invention belongs to iron and steel enterprise's field of mechanical technique, more particularly to a kind of coal gas of converter pipe network system that improves protects energy supply
The method of power.Production suitable for integrated iron and steel works' coal gas system supplies with protecting.
Background technology
General iron and steel enterprise coal gas of converter pipe network is usually that single seat gas chamber is connected in converter gas system, this kind of mode
Small investment, plant maintenance amount relatively less, system operation it is simple.But turn gas holder need to stop the supple of gas or steam overhaul when, it is necessary to pipe network disconnect, turn
Producer gas pipe network will stop supplying, and reduce the guarantor's energy supply power for turning gas pipe network system.Each coal gas of converter user needs to stop production；It is precious
The TECHNIQUE TO LARGE INTEGRATED STEEL WORKS coal gas of converter pipe network system such as steel, Shoudu Iron and Steel Co employs the method for operation of double gas holders gas storage arranged side by side, the party
The advantages of formula is because of single seat overhaul gas container or will not to move back pipe network operation and influence to turn the overall operation of gas system, coal gas of converter pipe
There is net system stronger guarantor to energize power.But the shortcomings that double cabinet gas storage methods of operation is that system cost is higher, maintenance is larger, behaviour
Make complicated.
The content of the invention
It is an object of the invention to provide a kind of method for improving coal gas of converter pipe network system and protecting energy supply power, solves coal gas
When cabinet failure or maintenance out of service, the problem of coal gas of converter user is unable to normal use.Enhance coal gas of converter pipe network system
Guarantor energize power.
A kind of method for improving coal gas of converter pipe network system and protecting energy supply power, specific steps and parameter are as follows：
1st, blast furnace gas calorific value 3300-3800kJ/m3, heating value of natural gas 33000-36000kJ/m3, by blast furnace gas and day
Right throughput presses 7:1-9:1 range scale is mixed, mixed gas calorific value 7000-9000 kJ/m3, with coal gas of converter calorific value
It is close, meet each coal gas of converter user technological requirement.
2nd, a set of gas mi xture system and control system are set up between converter gas cabinet and compression system, i.e. coal gas mixes
Stand.Coal gas mixing station is made up of two-way pipeline, is all the way natural gas line, and natural gas blank-plate valve 1, natural balloon are installed on pipeline
Valve 2 and natural gas electric control valve 3；Another way is blast furnace gas pipeline, and high gas blank-plate valve 4 and high pneumoelectric dynamic two are installed on pipeline
Inclined valve 5.The mixed gas of the hybrid station is confessed pipeline and is directly connected with Pressure Unit inlet manifold.
3rd, open the high pneumoelectric of hybrid station and move two inclined valves 5, pressuring machine power-on operation is performed by related code.
4th, return valve is opened, slow to open turnover panel before pressuring machine machine, control sends out pressure in the range of 16-20kpa.
5th, delay and drive hybrid station natural gas electric control valve 3, blast furnace gas and gas discharge are pressed 7:1-9:1 scope ratio
Example is mixed；Control sends out pressure and meets that user requires.
The advantage of the invention is that：The Pressure Unit inlet manifold of coal gas of converter pipe network system is additionally arranged coal gas mixed stocker
System, the hybrid system can be put into operation at any time, and the flow and calorific value of mixed gas, the mixing are controlled by regulating valve and flowmeter
Stand using blast furnace gas system as support, its stable equivalent to one large-scale gas chamber of gas supply capacity.When converter gas pipeline system
System recovers normal, it is only necessary to closes contacting for the i.e. cut-off hybrid station of blank-plate valve and converter gas system.Effectively increase converter
The guarantor of coal gas system energizes power and stability, it is ensured that main flow production process normally produces.Content is most in blast furnace gas three kinds
Gas is respectively N2、CO、CO2, three kinds of most gases of content are respectively CO, N in coal gas of converter2、CO2。N2With CO2It is inertia
Gas, therefore blend a small amount of natural gas in blast furnace gas and improve calorific value, exhaust gas components produce without large change to gas equipment
Technique is without considerable influence.Present invention design is simple and practical, is adapted in steel industry, especially to only having the converter of single seat gas chamber
Promote, use in gas piping system.
Brief description of the drawings
Fig. 1 is position view of the present invention in coal gas of converter pipe network.Wherein, natural gas blank-plate valve 1, natural gas ball valve
2nd, natural gas electric control valve 3, high gas blank-plate valve 4, high pneumoelectric move two inclined valves.
Embodiment
A kind of method for improving coal gas of converter pipe network system and protecting energy supply power, specific steps and parameter are as follows：
1st, as blast furnace gas calorific value 3300kJ/m3, heating value of natural gas 33000kJ/m3, by blast furnace gas and gas discharge
By 7:1 ratio is mixed, mixed gas calorific value 7000kJ/m3, it is close with coal gas of converter calorific value, it can meet that each coal gas of converter is used
Family technological requirement.
2nd, a set of gas mi xture system and control system are set up between converter gas cabinet and compression system, i.e. coal gas mixes
Stand.Coal gas mixing station is made up of two-way pipeline, is all the way natural gas line, and natural gas blank-plate valve, natural balloon are installed on pipeline
Valve and natural gas electric control valve；Another way is blast furnace gas pipeline, and high gas blank-plate valve is installed on pipeline and high pneumoelectric dynamic two is inclined
Valve.The mixed gas of the hybrid station is confessed pipeline and is directly connected with Pressure Unit inlet manifold.
3rd, open the high pneumoelectric of hybrid station and move two inclined valves 5, pressuring machine power-on operation is performed by related code.
4th, return valve is opened, slow to open turnover panel before pressuring machine machine, pressure 18kpa is sent out in control.
5th, delay and drive hybrid station natural gas electric control valve 3, blast furnace gas and gas discharge are pressed 7:1 ratio is mixed
Close；Control sends out pressure and meets that user requires, notifies that user resumes production by igniting use.
