Whether electric precipitation inlet flue gas temperature is greater than the set value；
4) if so, by crossbeam porcelain axis heating operation interface, porcelain axis crossbeam heating device is shut down out of service；
5) if it is not, heating device continues to heat electric precipitation porcelain axis crossbeam, until smoke temperature is greater than the set value, it will be described
Heating device is shut down out of service.
Preferably, further include step 6)：Check whether the crossbeam porcelain axis heating device for needing to stop transport is all out of service.
Preferably, it is described unit starting for the previous period be 40-48 hours.
Preferably, the set grid-connection and stable operation are 20-30 hours for a period of time.
Preferably, the setting value is 100-130 degree.
Through the above technical solutions, the beneficial effects of the invention are as follows：By before unit starting 40-48 hours by electric precipitation
Porcelain axis crossbeam heating device is put into, and in set grid-connection, simultaneously stable operation 20-30 as a child exited the heating of porcelain axis crossbeam, reduced
The power consumption of electric precipitation, and reduce the replacement frequency of the electrical equipments such as heating element, contactor, equipment loss rate is reduced, inspection is reduced
Repair expense.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
Specific implementation mode
The specific implementation mode of the present invention is described in detail below.It should be understood that described herein specific
Embodiment is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
The present invention provides a kind of method reducing electric precipitation power consumption, and the operation before breaking is theoretical, logical according to unit operation
After flue gas, electric precipitation interior environment temperature is high, will not junction leakage the case where climbing electricity, not interfering with the operation of electric field, after unit operation
Stoppage in transit crossbeam magnetic axis heats.Summer fair weather, operating unit electric precipitation porcelain axis external female beat skin temperature and reach 80 DEG C or more,
Crossbeam skin temperature reaches 60 DEG C or more, it is not necessary that input heating device；According to winter operation situation, porcelain axis crossbeam is in outer
Inside shell, during operation, for smoke temperature at 100 DEG C or more, temperature should be apparently higher than cold air, and surface will not occur low temperature moisture condensation and ask
Topic, heating device can also be out of service.
The present invention provides a kind of method reducing electric precipitation power consumption, includes the following steps：
1) unit starting for the previous period, by electric precipitation porcelain axis crossbeam heating device put into heat；
2) start unit, when set grid-connection and stable operation for a period of time after, acquisition electric precipitation inlet flue gas temperature monitoring point
Temperature, and the temperature is uploaded in monitoring system；
3) it by observing the smoke temperature curve of the electric precipitation inlet flue gas temperature monitoring point shown in the monitoring system, determines
Whether electric precipitation inlet flue gas temperature is greater than the set value；
4) if so, by crossbeam porcelain axis heating operation interface, porcelain axis crossbeam heating device is shut down out of service；
5) if it is not, heating device continues to heat electric precipitation porcelain axis crossbeam, until smoke temperature is greater than the set value, it will be described
Heating device is shut down out of service.
In addition, summer fair weather, operating unit electric precipitation porcelain axis external female beats skin temperature and reaches 80 DEG C or more, crossbeam
Skin temperature reaches 60 DEG C or more, it is not necessary that input heating device；Winter operation situation is speculated according to convention, at porcelain axis crossbeam
During enclosure, operation, for smoke temperature at 100 DEG C or more, temperature should be apparently higher than cold air, and low temperature knot will not occur for surface
Dew problem, heating device can also be out of service.
6) check whether the crossbeam porcelain axis heating device for needing to stop transport is all out of service.
Specifically, as a preferred embodiment, it is described unit starting for the previous period be 40-48 hours,
To prevent surface low-temperature condensation from causing creeping discharge.
In addition, simultaneously stable operation is 20-30 hours for a period of time to set grid-connection, can guarantee that flue-gas temperature is more than setting
Value, as a preferred embodiment, setting value is 100-130 degree, at this time, it is not necessary that put into heating device, smoke temperature again
It is apparently higher than cold air, low temperature condensation trouble will not occur for surface, and heating device can be out of service.
Most preferably, proved by a large number of experiments, before unit starting 48 hours by electric precipitation porcelain axis crossbeam heating device
Input heating, after set grid-connection and stable operation 24 hours, porcelain axis crossbeam heating device is shut down it is out of service, at this point, electric
Dedusting power consumption is minimum.
With the electric precipitation consumption rate deck watch under generated energy：
It is compared according to the above test data, after crossbeam magnetic axis heating summer exits, under load, electric precipitation power consumption reduces
More apparent, electric precipitation consumption rate averagely reduces by 0.0472% daily, and single machine increases by 23.65 ten thousand yuan of income, reduces net coal consumption rate
0.16g。
Conclusion：Summer can execute optimization operating scheme, by electric precipitation porcelain axis after unit ignition is run 20-30 hours
Crossbeam heating is all exited, and under the premise of can ensure that electric precipitation reliability service, can reduce station service power consumption rate, implementation effect is bright
It is aobvious.
Therefore, electric precipitation operation before, continuous synchronization is run during being all the heating random groups operation of crossbeam porcelain axis, and electricity removes
Dirt consumption rate is big, and the operation before this innovation point is to break is theoretical, after leading to flue gas according to unit operation, inside electric precipitation
Environment temperature is high, will not junction leakage the case where climbing electricity, not interfering with the operation of electric field, stoppage in transit crossbeam porcelain axis heats after unit operation,
Any fund is not spent, station service only can be reduced according to the adjustment of live operating condition, has saved a large amount of expenses, unit fortune
The operation of 20-30 hours backed off after random electric precipitation crossbeam magnetic axises of row heating can reduce heating while not only reducing auxiliary power consumption
The replacement frequency of the electrical equipments such as element, contactor reduces equipment loss rate, reduces maintenance expense.
To sum up, the method provided by the invention for reducing electric precipitation power consumption, was removed electricity by 40-48 hours before unit starting
Dirt porcelain axis crossbeam heating device is put into, and is heated porcelain axis crossbeam after set grid-connection and stable operation 20-30 hour and is exited, does not throw
Any expense is provided, combustion adjustment is only passed through, so that it may which to reduce the power consumption of electric precipitation, and reduction heating element, contactor etc. are electrical
Replacement of element frequency reduces equipment loss rate, reduces maintenance expense.
The preferred embodiment of the present invention has been described above in detail, still, during present invention is not limited to the embodiments described above
Detail can carry out a variety of simple variants to technical scheme of the present invention within the scope of the technical concept of the present invention, this
A little simple variants all belong to the scope of protection of the present invention.
