Abstract
The utility model provides a kind of air preheater temperature control shunting device.No.1 solenoid valve is housed, the hot air duct of air preheater outlet is provided with temp probe, No. two solenoid valves is housed on bypass duct, cold air duct is connected with hot air duct by bypass duct on the cold air duct of the air preheater entrance in described device.The device is adjusted air preheater and exports wind-warm syndrome, accomplishes that the wind-warm syndrome of air preheater outlet artificially can be adjusted and control, and can control the wind-warm syndrome after air preheater leakage, can switching control mode immediately after the air quantity leakage of air preheater.
Description
Technical field
The utility model relates to arrive power plant equipment field, it is related specifically to a kind of air preheater temperature control shunting device.
Background technique
Air preheater, the wind in existing tube-type air preheater are respectively arranged on the electricity generation boiler pipeline of most of bio-power plants
Temperature is random groups load operation mode and is fluctuated, and wind-warm syndrome is substantially available without regulating measure, after air preheater air leakage,
It is controlled on production line without effective means.
Summary of the invention
The purpose of this utility model is to provide a kind of using bypass duct to the outlet temperature of air preheater and wind after leaking out
Measure the air preheater temperature control shunting device controlled.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of air preheater temperature control shunting device, comprising: cold air duct, No.1 solenoid valve, air preheater, hot air duct, temperature
Probe, No. two solenoid valves, bypass duct and control room, equipped with No.1 electricity on the cold air duct of the air preheater entrance in described device
Magnet valve, the hot air duct of air preheater outlet are provided with temp probe, No. two solenoid valves, cold air duct and heat are housed on bypass duct
Air piping is connected by bypass duct.
No.1 solenoid valve, temp probe and No. two solenoid valves in described device are connected with conducting wire with control room respectively.
Compared with prior art, the good effect of the utility model are as follows:
1, the device is adjusted air preheater and exports wind-warm syndrome, accomplishes that the wind-warm syndrome of air preheater outlet artificially can be adjusted and control
System；
2, the device can control the wind-warm syndrome after air preheater leakage, after the air quantity leakage of air preheater, can switch control immediately
Molding formula；
3, the apparatus structure is simple, operates and easy to control, is conducive to promote.
Detailed description of the invention
Fig. 1, air preheater temperature control shunting device structural schematic diagram.
In figure: 1, cold air duct, 2, No.1 solenoid valve, 3, air preheater, 4, hot air duct, 5, temp probe, 6, No. two electricity
Magnet valve, 7, bypass duct, 8, control room.
Specific embodiment
Clear, complete description further is carried out to the technical solution of the utility model with reference to the accompanying drawing.
Referring to attached drawing 1, when the hot air duct 4 that the temp probe 5 in hot air duct 4 detects electricity generation boiler needs to drop
When low wind-warm syndrome, temp probe 5 is transferred signals in control room 8, opens No. two filled on bypass duct 7 by control room 8
Solenoid valve 6 simultaneously closes off the No.1 solenoid valve 2 on cold air duct 1, the cold wind in cold air duct 1 without air preheater 3, and from
Bypass duct 7 enters directly into hot air duct 4, reduces the wind-warm syndrome in hot air duct 4.When temp probe 5 detects hot wind
When wind-warm syndrome in pipeline 4 is too low, temp probe 5 is transmitted a signal in control room 8, is closed on bypass duct 7 by control room 8
No. two solenoid valves 6 filled, open simultaneously No.1 solenoid valve 2, enter the cold wind in cold air duct 1 in air preheater 3 and heat,
It enters back into hot air duct 4.The wind-warm syndrome in hot air duct 4 is adjusted and is controlled with this mode.
