Wind pressure signal controls 9 running frequency of booster fan, is allowed to be within the scope of stable wind pressure, the stabilization run with supercharging equipment
Property.
The specific of the deslagging device of boiler slag uses and to control process as follows in the present embodiment：
One, using process
(1) debugging mode：Equipment installs, and when boiler not running, starting trouble air-introduced machine 5 first restarts supercharging
Then wind turbine 9 adjusts smoke regulating valve 12 and air control valve 14, observe T values, the P values of wind pressure measuring point 11 of temperature point 10
And record, wherein 9 variable ratio frequency changer of booster fan adjusts running frequency, and the valve opening of smoke regulating valve 12 and air control valve 14 can
To be adjusted between 0-100%.
(2) it enables
1, starting trouble the, wherein (temperature determined when by practical debugging when the T values of temperature point 10 are 600 DEG C or so
Value) it can determine that as boiler normal operation；
2, booster fan 9 is opened to certain frequency, and the P values at observation wind pressure measuring point 11 are just set to 3-5kPa, with from falling ash
The industry visor 22 at 2 that struggles against observes at fluidized plate 7 that dust stratification be not to be suitble to wind pressure (the wind turbine frequency being suitble to)；
3, when above " 2 " state, smoke regulating valve 12 is fully closed, 14 standard-sized sheet of air control valve；
4, when normal operation, the T values of temperature point 10 are within the scope of 400~600 DEG C, if T>It 900 DEG C, can determine that as pot
The uncombusted carbon component of stove burns in ash bucket, should suitably open big smoke regulating valve 12 (ascending) at this time, turn down air tune
Air door (descending), to maintain air compartment wind pressure 11 constant or appropriate increase (10%-20%) so that the uncombusted carbon of boiler at
Divide and fully burn in ash bucket, to reduce temperature；If T>At 1150 DEG C, it can determine that have coking possibility, Ying Shi in ash dropping hopper 2
When opening big smoke regulating valve 12 (ascending), air air register (descending) is turned down, to maintain wind pressure P values constant or suitable
When increasing wind pressure P values (10%-20% can be increased), the generation of coking is avoided, to make temperature reduce, and it is made to ensure lime-ash
It blows away；
5,9 suitable running frequency of booster fan is thus set.
(3) it deactivates
After determining boiler shutdown first, it is then shut off booster fan 9 and smoke regulating valve 12 and air control valve 14.
Two, automatic control process
The deslagging device of boiler slag can select continuous operation operation or selection interval according to actual production status
Operation operation.
1) control of wind pressure：Wind pressure measuring point 11, booster fan 9 in ash dropping hopper 2 are connected with electronic control unit 15, pass through
It is suitably adjusted after debugging process and startup after determining suitable wind pressure value P, and this wind pressure value P is set by electronic control unit 15,
In the process of running, when wind pressure value changes, the running frequency of 15 automatic control and adjustment booster fan 9 of electronic control unit so that wind pressure
In value stabilization range suitable above or below wind pressure value P.
2) control of temperature：Temperature point 10, smoke regulating valve 12 at ash dropping hopper 2, air control valve 14 and supercharging wind
Machine 9 is connected with electronic control unit 15, has when continuous operation operation and intermittent duty operate for the control of temperature different
Control process.
Continuous operation operates：Booster fan 9 is controlled by the temperature signal of reception and is adjusted in running hours, electronic control unit 15
Save the aperture of the aperture and air control valve 14 of smoke regulating valve 12 so that deslagging device is in continuous operation state.
When normal operation, the T values of temperature point 10 are within the scope of 400~600 DEG C.
Work as T>At 900 DEG C, it can determine that and burn in ash bucket for the uncombusted carbon component of boiler, temperature signal is sent at this time
Control unit, control unit control suitably open big smoke regulating valve 12 (ascending), turn down air control valve 14 (by greatly to
It is small), maintain wind pressure P values constant at this time so that the uncombusted carbon component of boiler fully burns in ash bucket, to reduce temperature recurrence
Normal range (NR).
Or big smoke regulating valve 12 is being opened, and it is appropriate to increase wind pressure value P while turning down air control valve 14, increase model
It can be 10~20% to enclose, for example, wind pressure value is former 1.2 times of setting value, i.e. wind pressure in control change " the 1) " item of electronic control unit 15
Value is 1.2P, and then 9 adjust automatically running frequency of booster fan makes wind pressure value stabilization within the scope of the wind pressure after change；Work as T<
At 900 DEG C, smoke regulating valve 12, standard-sized sheet air control valve 14 are closed in the control of electronic control unit 15, while being changed recovery wind pressure value and being
Former setting value P, that is, state when being restored to startup when normal operation.
Work as T>At 1150 DEG C, can determine that for have in ash dropping hopper 2 coking may, continue out big smoke regulating valve 12 (by it is small to
Greatly), air control valve 14 (descending) is turned down, the combustion chamber 1 of boiler is enable fully to burn, maintains wind pressure P values not at this time
Become, avoids the generation of coking, to make temperature reduce, and make its guarantee that lime-ash is blown away.
Or big smoke regulating valve 12 is being opened, and it is appropriate to increase wind pressure value P while turning down air control valve 14, increase model
It can be 10~20% to enclose, for example, wind pressure value is former 1.2 times of setting value, i.e. wind pressure in control change " the 1) " item of electronic control unit 15
Value is 1.2P, and then 9 adjust automatically running frequency of booster fan makes wind pressure value stabilization within the scope of the wind pressure after change；Work as T<
At 900 DEG C, smoke regulating valve 12, standard-sized sheet air control valve 14 are closed in the control of electronic control unit 15, while being changed recovery wind pressure value and being
Former setting value P, that is, state when being restored to startup when normal operation.
Intermittent duty operates：Electronic control unit 15 controls the opening of booster fan 9 by the temperature signal of reception, stops so that goes out
Slag device is in intermittent operating state.
When normal operation, the T values of temperature point 10 gather thickness within the scope of 400~600 DEG C, with the lime-ash of ash dropping hopper 2
The temperature of the increase of degree, temperature point 10 can accordingly increase.
When temperature reaches the temperature T of setting1When, that is, work as T>T1When (such as T1Can be 900 DEG C), electronic control unit 15 at this time
It controls booster fan 9 to start, the lime-ash in ash dropping hopper 2 be purged, hereafter the temperature value T of temperature point 10 can drop accordingly
It is low.
When temperature is reduced to the temperature T of setting2When, that is, work as T<T2When (such as T2Can be 450 DEG C), electronic control unit at this time
15 control booster fans 9 are out of service, and hereafter lime-ash starts to gather at ash dropping hopper 2, and the temperature of temperature point 10 starts to increase, when
The temperature of temperature point 10 rises to T again1When, electronic control unit 15 controls booster fan 9 and starts, and is moved in circles with this, carries out
Intermittent duty operates.
Certainly, when the deslagging device of boiler slag using a period of time, and it is stable when, can be according to booster fan
The working condition of 9 intermittent duties obtains 9 run time of booster fan and interval time, is then set and is closed by electronic control unit 15
Suitable run time and interval time is operated with this to control the intermittent duty of the deslagging device of boiler slag.
Above-described specific temperature value T and wind pressure value P is to be best understood from the Boiler Furnace of the embodiment of the present invention
The referential data of the deslagging device of slag provided using process and control process, certainly due to different production scales, difference
Production equipment, actual set reference value would also vary from.
