Description
Technical field
The utility model relates to field of environment protection, particularly a kind of insulated electro insulator for glass furnace hot electrostatic precipitator.
Background technology
At present, glass furnace adopts natural gas, coal gas, petroleum coke, coal tar, heavy oil etc. as fuel usually.When adopting natural gas, coal gas, kind of dust is lower, is about 200 ~ 350mg/Nm3; But mix in glass enterprise and burn petroleum coke powder, coal tar, heavy oil etc. still very generally, now dust concentration is about 600 ~ 900mg/Nm3.
The dust that the glass furnace being fuel with petroleum coke powder or natural gas produces after combustion is comparatively thin, and flue gas moisture content is higher when taking natural gas as fuel, and when taking petroleum coke powder as fuel, dust viscosity is comparatively large, and hygroscopicity is strong.Hot electrostatic precipitator is in glass furnace dedusting application process, and low melting point, oiliness, thinner dust can be adsorbed on insulator inwall, occurs negative electrode suspension rod degree of depth fouling phenomenon.Insulated porcelain sleeve inwall reduces the distance between negative electrode suspension rod and insulator inwall after there occurs degree of depth dust stratification, the shortening of distance can increase the potential difference of insulator bottom dust cover inside and outside wall dust layer, creepage phenomenon can be produced when potential difference increases to certain value, reduce secondary voltage and electric current, dust collector efficiency can decline; Even insulator inwall is adhered to rear easy generation spark discharge and is caused insulator and burst, and affects the operation of whole dust pelletizing system.Breaking of insulator not only increases replacing, operation expense, also have impact on the normal operation of glass furnace.At present; for avoiding occurring above situation; some producers adopt certain online ash removal mode at dust cover top blowing pressurized air deashing, or change dust cover form utilizes the swirling eddy deashing entered in dust cover, or directly artificial deashing replacing insulator is carried out in shutdown.
Because dust viscosity in glass furnace is comparatively strong, easily stick on electroceramics cover inside or negative electrode suspension rod, existing purge mode effect is not very desirable.When adopting compressed air deashing, the dust adhesion produced due to combusting heavy oil is very strong, not obvious electroceramics cover, negative electrode suspension rod or the dust cover bottom dust stratification situation of causing on the contrary of ash-removal effect is more serious, stick to the dust meeting fouling on inwall, dust layer thickness can increase from top to bottom gradually, is difficult to Automatic-falling.Insulator insulating properties can significantly reduce, and easily cause high pressure creepage phenomenon, reduce efficiency of dust collection, even can cause insulator Yin Gaowen and hot tearing.Enter the swirling eddy of dust cover inside, its ash-removal effect is also undesirable, cannot reach the effect of deashing.As there occurs degree of depth dust stratification, secondary voltage and electric current can be caused to reduce, affect the efficiency of electric cleaner.Because glass furnace comparision of production is continuous, shut down that to carry out artificial deashing cost higher, and existing dust cover structure is general comparatively complicated, installation and maintenance are changed more difficult, and frequent insulator cost of changing also can increase.
