Description

The purging heater control device of electrostatic (electric dust) precipitator
Technical field
The present invention relates to a kind of purging heater control devices of electrostatic (electric dust) precipitator, more particularly to one kind is only in necessary shape The purging heater of the insulator room of electrostatic (electric dust) precipitator will be supplied to by starting under condition after heating external air, to reduce the energy Unnecessary waste electrostatic (electric dust) precipitator purging heater control device.
Background technique
In general, dust arrester is a kind of device that using electrostatic force the particles such as dust are carried out with dust, put using corona Electricity and so that contaminated dust (Dust) to be processed and mist (Mist) is ionized and is attached to collecting plate and is located Reason.At this point, supply high voltage power supply in order to carry out corona discharge to discharge electrode and use, and in order to support discharge electrode and Collecting plate simultaneously makes it insulate and uses the insulator to insulate inside dust arrester.The insulator of internal insulation is set to because of medium The problem of breakdown and ensure space so that main frame (Main Frame) can pass through.
But contaminated dust and mist enter this space and pollute insulator surface, this, which becomes, causes medium The reason of breakdown, function paralysis and fire.To solve the above-mentioned problems, predetermined amount is blown into the insulator room of electrostatic (electric dust) precipitator The reason of outside air and the moisture condensation that prevents from polluting, but generate by inside and outside temperature difference may also become dielectric breakdown, institute Dielectric breakdown is solved the problems, such as to supply the air of heating using heater (Heater).
Fig. 1 is the figure for showing the composition of the existing air for being heated to electrostatic (electric dust) precipitator supply.
Referring to Fig.1, electric based on height in the insulator room 23 formed using the side of the dust storage chamber 21 in electrostatic (electric dust) precipitator 20 The discharge electrode of the insulator (Insulators) of pressure and carry out dust, and moisture is generated due to the insulation based on high voltage. Moisture is generated in insulator room 23 in order to prevent, the air of high temperature is blowed to insulator room 23 and makes to maintain inside insulator room 23 Dry state, to prevent dielectric breakdown.
As shown in Figure 1, heated in order to be supplied to the insulator room 23 for 21 side of dust storage chamber for being formed in electrostatic (electric dust) precipitator 20 Outside air (Outside Air), have fan 11 and heater 13, independently with dust agglutination, outside air is borrowed Help fan 11 and heater 13 and obtain flowing into insulator room 23 after heating, to prevent foreign matter or moisture from penetrating into The insulator of insulation.
But in order to supply outside air after laser heating to prevent the moisture generated in insulator room 23 from condensing Phenomenon, heater 13 need continuous work, and thus can consume unnecessary electric power.For example, the pollution of insulator in order to prevent And moisture condensation, the outside air of predetermined temperature is supplied using fan 11 and heater 13 in insulator room 23, is thus solved Problem, but in winter in, heater 13 will be excessively used in order to maintain predetermined temperature, it is possible that generating excessive energy Source loss.
