Description
Technical field
This utility model relates to a kind of power plant fire inspection cooling air system, belongs to thermal power plant flame detection system technical field.
Background technology
Each power plant is due to the design problem of fire inspection blower fan at present, and the accident causing fire inspection fan vibration to damage motor frequently occurs, and flame detecting probe coking or scaling loss often occurs, adds the maintenance cost of boiler, and had a strong impact on the safe operation of boiler.
Utility model content
For solving the technical problem that prior art exists, this utility model provides a kind of simple in construction, easy to use, it is possible to effectively to cool down flame detecting probe, prevents the power plant fire inspection cooling air system that flame detecting probe damages.
For achieving the above object, the technical scheme that this utility model is used is power plant fire inspection cooling air system, including fire inspection blower fan and flame detecting probe, described fire inspection blower fan is connected with main line by the first pipeline, connect on described main line and have flame detecting probe, it is provided with the first three way cock between described first pipeline and main line, described first three way cock is also associated with the second pipeline, connect on described second pipeline and have stock fire to examine blower fan, it is provided with the first control valve on described first pipeline, the second control valve it is provided with on second pipeline, described main line is also associated with the 3rd pipeline, connected by the second three way cock between described 3rd pipeline and main line, described 3rd pipeline is connected with cold primary air piping, it is provided with non-return valve on described 3rd pipeline.
Preferably, also include main control unit, being provided with pressure transducer and Pressure gauge on described main line, described fire inspection blower fan, stock fire inspection blower fan, the first control valve, the second control valve, pressure transducer are all connected with main control unit with Pressure gauge, and described main control unit is provided with display screen.
Compared with prior art, this utility model has following technical effect that this utility model simple in construction, easy to use, when boiler is properly functioning, use cold First air that flame detecting probe is cooled down, disable fire inspection blower fan, reduce station service power consumption rate, reduce fire inspection blower fan maintenance cost, greatly reduce the probability of flame detecting probe scaling loss, save cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figure 1, power plant fire inspection cooling air system, including fire inspection blower fan 1 and flame detecting probe 2, fire inspection blower fan 1 is connected with main line 4 by the first pipeline 3, connect on main line 4 and have flame detecting probe 2, the first three way cock 5 it is provided with between first pipeline 3 and main line 4, first three way cock 5 is also associated with the second pipeline 6, connect on second pipeline 6 and have stock fire to examine blower fan 7, the first control valve 8 it is provided with on first pipeline 3, the second control valve 9 it is provided with on second pipeline 6, main line 4 is also associated with the 3rd pipeline 10, connected by the second three way cock 11 between 3rd pipeline 10 and main line 4, 3rd pipeline 10 is connected with cold primary air piping 12, it is provided with non-return valve 13 on 3rd pipeline 10.
Also include main control unit 14, pressure transducer 17 and Pressure gauge 15 it is provided with on main line 4, fire inspection blower fan 1, stock fire inspection blower fan the 7, first control valve the 8, second control valve 9, pressure transducer 14 are all connected with main control unit 14 with Pressure gauge 15, and main control unit 14 is provided with display screen 16.
When specifically used, when boiler is properly functioning, the first control valve 8 and the second control valve 9 are closed, fire inspection blower fan 1 and stock fire inspection blower fan 7 quit work, and use cold primary air piping to cool down flame detecting probe, thus reduce station service power consumption rate, reduce the maintenance cost of fire inspection blower fan, effectively save cost.Pressure transducer 14 is for the pressure of monitoring main line in real time, Pressure gauge 15 is for the pressure value of display main line in real time, and force value is shown in real time on main control unit, when the force value of main line is less than 6Kpa, main control unit controls open the first control valve and start fire inspection blower fan, cools down flame detecting probe.If operating fire inspection blower fan emergency stop valve trip, main control unit controls to open the second control valve and stock fire inspection blower fan, it is ensured that flame detecting probe safe operation.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, in the range of all should wrapping in this utility model.
