Description
Technical field
Power plant place apparatus field is arranged in the utility model, specially a kind of top electro-magnetic vibrator electric precipitator vibration
Beat shaft insulation water-tight device.
Background technique
Certain Power Plant No.1, No. 2 unit dedusters rapping mode selects is top rapping.Top rapping is i.e. using installation
Electromagnetism hammer vibrator at the top of electric precipitation, which is acted on rapping by the vibrating rod being installed in the incubator of deduster top, to be passed
It is delivered on cathode and anode system or the airflow distribution device inside deduster, achievees the purpose that vibration dust-cleaning.Shaft insulation, that is, macromolecule
Composite insulator rapping stick is a part of cathode rapping bar, is located in incubator, the impact effect vibrated for transmitting top
High voltage inside deduster and extraneous is isolated simultaneously.
Normal environment in the incubator of deduster top is high temperature, drying, to guarantee the insulation performance of shaft insulation.By the external world
The influence of the factors such as weather, temperature, humidity or maintenance craft will appear dew condensation phenomenon in incubator once in a while.By dioxy in flue gas
Change the influence of sulphur, nitrogen oxides, contains the very strong acidic materials of a large amount of electric conductivity in condensation.Condensation evaporation is not in time or condensation
Certain amount is gathered, will be flowed downward along rapping shaft insulation.When water flow containing various conductive materials flows through rapping stick,
Current path is formed with the earth under the action of cathode 70kV even higher voltage, rapping insulating bar is short on the surface that water flow is formed
It burns, be carbonized under the high energy heat effect that road earth current generates, penetrability breakdown occurs, until losing insulation performance.At this time
The corresponding deduster electric field insulation breakdown of rapping shaft insulation, it has to it is out of service, reduce deduster entirety efficiency of dust collection, shadow
Ring the discharge index of flue dust.If multiple electric fields are out of service because rapping stick punctures, it will lead to house outlet smoke content
It is significantly increased, dust collector efficiency is decreased obviously, and chimney breast soot emissions are exceeded, and to avoid environmentally friendly examination, it is negative that unit is forced limit
Lotus operation or even unplanned outage defect elimination.
Following shortcoming exists in the prior art: 1, keeping the temperature upper box part manhole door, decorative pattern plate welding seams, rapping shaft insulation and wears
The positions such as wall position seal clearance are poorly sealed, may cause steam and enter incubator, encounter heavy rainfall or environment temperature rapid drawdown
When, steam is in incubator part condensation；2, rapping shaft insulation currently used electric heating and flows through deduster in incubator
Flue gas smoke temperature drives the measure of tide, is insufficient for the needs that condensation evaporates in incubator；3, rapping shaft insulation itself does not prevent
Because of the safeguard procedures that rapping stick insulation penetrability punctures caused by water flow；4, more than two electric fields because insulation breakdown it is out of service
When, it will lead to deduster power output critical constraints, unit load limit, or even defect elimination of stopping transport of having to, unit economy and reliability
It is decreased obviously.
Therefore it provides one kind can overcome the shortage of prior art, and it can play and rapping shaft insulation is played well
The device of waterproof action has been a good problem to study.
Summary of the invention
In order to overcome the deficiencies in the prior art described above, it is simple that the utility model provides a kind of structure, by rapping
The structure for installing waterproof cover on shaft insulation additional carries out the top electro-magnetic vibrator that practice rapping shaft insulation has good waterproof effect
Electric precipitator rapping shaft insulation water-tight device.
Purpose of the utility model is realized as follows:
A kind of top electro-magnetic vibrator electric precipitator rapping shaft insulation water-tight device, including rapping shaft insulation 1, Yi Jishe
The shaft insulation sleeve 5 on rapping shaft insulation 1 is set, is provided with waterproof cover 3 below the shaft insulation sleeve 5；
The insulating sleeve 5 is located at outside shaft insulation removal hole 2, and waterproof cover 3 is welded in 2 lower section of shaft insulation removal hole
On shaft insulation sleeve 5；
The waterproof cover 3 is under shed full skirt shape structure, is installed by two semicircle splicings；It is arranged on waterproof cover 3
There is the water storage tank 4 of multi-stage annular；
The full skirt of the waterproof cover 3 is in 13~15 degree of inclinations angle；And it is not less than the stainless steel material of 2mm using thickness,
Corrosion-resistant coating is provided on stainless steel material；
The waterproof cover 3 is using structures to form is fully welded, and installation site is lower than below shaft insulation removal hole.
Positive beneficial effect: the utility model installs waterproof cover additional above rapping shaft insulation, by condensation convergence water flow from
Direct carrying-off, prevents it from flowing down along rapping stick above rapping stick；The anti-dewing ability for promoting rapping shaft insulation is prevented because a large amount of solidifying
The breakdown of rapping shaft insulation caused by dew；In the case where maintenance workload and security risk is not significantly increased, electricity is effectively reduced and removes
Dirt device electric field insulation defect incidence；Electric Field in ESP caused by being effectively reduced because of condensation problem exits problem, guarantees that electricity removes
Dirt device is run in design rating, improves unit economy and safety.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure are as follows: rapping shaft insulation 1, shaft insulation removal hole 2, waterproof cover 3, water storage tank 4, insulating sleeve 5.
Specific embodiment
With reference to the accompanying drawing, the utility model is described further:
