The discharge electrode works in a high-voltage state, and the suspension support of the discharge electrode needs to depend on insulators such as electroceramics or quartz and the like. The discharge electrode suspension device mainly has two forms: a double strut support form, a sleeve support form. The first mode is to use two support columns to support the discharge electrode in a hanging way and use an insulating cone sleeve to isolate the smoke in the dust remover. The second mode is to directly use the insulating cone sleeve to hang and support the discharge electrode and isolate the smoke in the dust remover. In both technologies, the flue gas in the dust remover needs to be isolated by using the conical sleeve.

Example 1:
referring to fig. 1-2, a quick cleaning and purging device for an inner wall of an insulating cone sleeve comprises a discharge electrode boom 5, a gas medium pipeline 15, a liquid medium pipeline 16, a gas valve 1, a liquid valve 2, a guide pipe 4, a tee joint 3, a first quick joint 9 and a second quick joint 10, wherein a channel 6 is axially formed in the discharge electrode boom 5, a spray hole group communicated with the channel 6 is formed in the outer circumferential surface of the discharge electrode boom 5, one ends of the gas valve 1, the liquid valve 2 and the first quick joint 9 are in threaded connection with the tee joint 3, the other ends of the gas valve 1 and the liquid valve 2 are respectively communicated with the gas medium pipeline 15 and the liquid medium pipeline 16, the other end of the first quick joint 9 is communicated with one end of the second quick joint 10 through the guide pipe 4, and the other end of the second quick joint 10 is communicated with the channel of the discharge electrode boom 5.
In actual use: before cleaning and purging the inner surface of the insulating cone sleeve 8, the operation of the electric field high-voltage silicon rectifying device is stopped, the electric field is grounded, residual charges in the electric field are subjected to short-circuit discharge, and the safety of cleaning and purging is ensured. The grounding short circuit line 12 is respectively connected to the hanging insulation box 13 and the discharge electrode hanging beam 14, then the gas valve 1 and the liquid valve 2 are communicated with a gas supply pipeline 15 and a liquid supply pipeline 16, then the first quick connector 9 is communicated with the guide pipe 4, the second quick connector 10 is communicated with the guide pipe 4,
when the inner wall surface of the insulating cone sleeve 8 is slightly adhered with objects, the gas valve 1 is opened, a gas medium enters the tee joint 3 through the gas valve 1, enters the guide pipe 4 through the first quick coupling 9, enters a channel in the discharge electrode suspender 5 through the second quick coupling 10, is sprayed out from the spray hole 7, is sprayed to the inner wall surface of the insulating cone sleeve 8 to be washed and cleaned, and the objects adhered to the inner wall surface of the insulating cone sleeve 8 are impacted, so that the purging effect is achieved.

The gas medium in this embodiment is air or nitrogen.
When the flue gas is combustible gas such as converter gas and blast furnace gas, the oxygen content of the flue gas is strictly controlled to prevent explosion. To prevent the incorporation of oxygen, only non-oxygen gases can be used as the purging medium, with nitrogen being the more readily available and less costly option.
When the flue gas is the flue gas of a general kiln such as a coal-fired boiler or a cement kiln, the change of the oxygen content in the flue gas does not need to be considered, so that compressed air can be adopted as a purging medium, the cost is low, and the acquisition is easy.
In this embodiment the liquid medium is water or alcohol.
In actual use: when the dust in the flue gas is dry and the moisture absorption and the adhesion of the dust are strong, water is used as a cleaning medium, so that the water is sprayed into the surface of the polar row at the lower part of the insulating taper sleeve and is likely to agglomerate with part of dust and adhere to the surface of the polar row, and the dust is unlikely to fall off, thereby affecting the discharge and dust collection of the polar row. Therefore, alcohol is used as a cleaning medium, and the volatility of the alcohol can prevent dust from caking and bonding. But the cost is high by adopting alcohol as a cleaning medium.
When dust collected on the polar row in the smoke meets water, the dust is not easy to agglomerate and is adhered to the surface of the polar row, water can be used as a cleaning medium, and the dust cleaning agent is low in cost and easy to obtain.

In this embodiment, the height of the inner wall surface of the insulating cone sleeve 8 is the same as that of the injection hole group, and 3 pairs of injection hole groups are used, and the injection holes 7 of each group are arranged in sequence.
The interval of the injection holes 7 in the present embodiment is 30MM to 50 MM.
Example 3:
on the basis of example 4, refer to fig. 4: the injection hole groups are at least two groups, and the injection hole groups are composed of at least two injection holes 7.
The spray holes 7 are arranged in the discharge electrode hanger rod 5 spirally upward in the axial direction at equal intervals.
