Description
Technical field
The utility model relates to tar-removing device, refers in particular to a kind of electrical tar precipitator polar curve and pole plate tar-removing device.
Background technology
Hot rolling energy gas station need establish electrical tar precipitator, and gas station coke oven gas pipe porch is located in this electrical tar precipitator position, the general electric purification device of cellular vertical and cylindrical adopting as shown in figure 11, and this electrical tar precipitator comprises housing 11; Be located at the several pole plates (dust collecting electrode) 12 that are the cellular layout of hexagon in housing 11; Be arranged on the middle polar curve 13 of each hexagon pole plate.Figure 12 is the enlarged diagram that is a hexagon pole plate in the pole plate of the cellular layout of hexagon in Figure 11, and each pole plate is hexagon, and two relative edges' spacing L is 48mm, has 283 pole plates.
Generally, electric purification device (electrical tar precipitator) is divided into decoking device body (deduster) and high-voltage rectifier two parts.High-voltage rectifier provides high voltage direct current, and high voltage direct current is delivered to the electrode (dust collecting electrode) of electric cleaner along high-tension cable.Dust collecting electrode connects positive terminal the ground connection of rectifier, and discharge electrode is insulation against ground, and it is attached to the negative pole end of rectifier.In the time that voltage is increased to certain certain numerical value, in dust collecting electrode and the interelectrode space of discharge electrode two, form corona discharge, result makes the particle generation directed movement of electric charge, between electrode, has electric current to pass through.Positive charge moves and is discharged utmost point neutralization to discharge electrode, and negative electrical charge moves to dust collecting electrode, has almost been full of negative electrical charge like this at two interpolars.
In the time containing suspended particles (dirt, mist) gas by interelectrode space, the particle charged (electronegative) that these particle passive movements, and also deposit in the above to electrode (dust collecting electrode) is mobile under electric field action, and the gas purifying is discharged from deduster by electric field.To reach the object of removing tar fog contained in coke-stove gas.And the tar fog under deposition needs regularly to remove on polar curve and pole plate, otherwise can affect the decoking efficiency of electrical tar precipitator.This is because when after a large amount of suspended particles of electrode (dust collecting electrode) surface deposition, negative electrical charge in space is attracted to deleterious, simultaneously due to interelectrode discharge process, can there is coming off to a certain degree in the tar particle that makes on the contrary to be originally attached to dust collecting electrode, the particle after coming off is sneaked into and in tar coal gas, entered follow-up pipe-line equipment.Must cause like this by the rising of the coke-stove gas coke content of deduster, thereby make coking degree aggravation in gas compressor, in running, just there will be vibration values to rise, affect the normal operation of pressuring machine.In follow-up pipeline, the rising of tar content, by affecting the quality (being mixing ratio) of mixed gas, brings certain impact to calorific value simultaneously, finally makes steel plate rolling quality occur the situation of fluctuation.So electrical tar precipitator is set is necessary in coke oven gas pipe porch and be necessary, the tar fog under simultaneously electrical tar precipitator being deposited on polar curve and pole plate also needs regular removing.
The tar mode depositing on existing removing electrical tar precipitator polar curve and pole plate generally has two macrospecies:
1, be a set of special water spray of electrical tar precipitator configuration tar-removing device.Under the state of stopping transport at electrical tar precipitator, by dedicated water spray equipment, the polar curve to electrical tar precipitator and pole plate carry out tar removing operation.
2, for electrical tar precipitator configuration steam decoking oil pipe carries out tar removing operation by passing into polar curve and the pole plate of steam to electrical tar precipitator under the state of electrical tar precipitator stoppage in transit.
Due to electrical tar precipitator internal electrode and pole plate employing metal material, surface attachment conductive material, steam and water clean and easily cause electrical tar precipitator internal water residual, thereby cause the significantly rising of corrosion risk, not only reduce tar clearance rate, carry out great potential safety hazard to gaspipe network equipment belt simultaneously.In addition, the overall system structure complexity of dedicated water spray equipment, need add the medicament of Special cleaning, and use cost is higher; Steam unit is to make to condense in tar on polar curve and the pole plate dirty object that has reached tar removing of liquefaction nature of being heated by steam high temperature, and its tar removing effect is poor.
Also the artificial tar removing operation of use having, 283 polar curves are extracted out from electrical tar precipitator is inner one by one, remove the tar sticking on polar curve, remove again pole plate, finally polar curve is put back to, because pole plate, the polar curve quantity of electrical tar precipitator are many, workload and difficulty are all larger, and in operation process, also may cause polar curve impaired.
