In the following, the application method by introducing stable-pressure device carries out the working principle of stable-pressure device of the present invention in conjunction with Fig. 2
It is described in detail.
In a specific embodiment, blast-furnace body is cooled down, wherein technique requires blast-furnace body cooling water
Pressure (that is: the water outlet pressure of sealing and circulating water cooling system) is maintained at 0.85MPa-0.87MPa, and expansion pressure tank is maintained at
The water level of 0.340MPa-0.345MPa, expansion drum require between A-D, water tank capacity 10m3, cistern water level requirement is in A-
Between C.
Wherein, the workflow of air supply unit are as follows: when the water outlet pressure of the sealing and circulating water cooling system is less than
0.85MPa alarm, the tonifying Qi valve of manually opened vacuum tank 11 are that air bag 31 supplements nitrogen, increase the pressure of expansion drum 3 extremely
Setting range, circulating pump water outlet pressure accordingly increases at this time, until the water outlet pressure of sealing and circulating water cooling system is close
11 tonifying Qi valve of vacuum tank is turned off manually at this time and stops mending nitrogen for 0.87MPa alarm.When 3 pressure of expansion drum is greater than
When 0.345MPa, safety valve 311, which automatically turns on, releases extra nitrogen, guarantees that the outlet pressure of sealing and circulating water cooling system is kept
0.85
Between MPa-0.87MPa, it is reached for the purpose of blast furnace stable water supply.Wherein, the benefit nitrogen valve of vacuum tank 11 and swollen
The safety valve 311 of swell can carry out manually | automatic conversion.It is swollen when the outlet pressure of sealing and circulating water system is more than 0.88MPa
The safety valve 311 of swell 3 automatically opens discharge excessive gas, until the outlet pressure of sealing and circulating water cooling system is lower than or waits
When 0.87MPa, the safety valve of expansion drum 3 is automatically closed, it is ensured that pressure of supply water is stable in setting range.
Wherein, the workflow of water supplying unit are as follows: when the liquid level of tank body 32 is lower than D point alarm, 22 two pumps of small pump
Start moisturizing, water level rises to B point alarm, and 22 two pumps of small pump stop moisturizing.When liquid level is lower than C point alarm, small pump
22 1 pump startup moisturizings, water level rise to B point alarm, and 22 1 pumps of small pump stop moisturizing.Water level is only reported when rising to A point
It is alert.When 21 liquid level of water tank is lower than C point alarm, water compensating valve opens moisturizing, and water level rises to B point alarm, and water compensating valve, which is closed, to be stopped
Moisturizing.Water level is only alarmed when rising to A point.Electronic water compensating valve and high water tank be connected to can manually converted automatically.
