Description
Technical field
The utility model relates to a kind of insulated porcelain sleeve inner surface blow device of supporting high temperature electrostatic deduster of glass furnace.
Background technology
The exhaust temperature of glass furnace is generally between 320-380 °, and belong to high-temperature flue gas, the granularity of dust wherein contained is little, and viscosity is high, and ratio resistance is low, and water imbibition is strong, and time especially using petroleum coke powder as fuel, Dust is more complicated.The insulated porcelain sleeve of electrostatic precipitator is important dust removal component, for negative electrode provides insulation protection, ensures normal table voltage when electric field runs.If insulated porcelain sleeve inner surface gathers a large amount of dust, very easily cause shelf depreciation, lose insulation effect, not only cause the loss for no reason of electric power data, and have a strong impact on the normal operation of electric field, even puncture insulated porcelain sleeve, cause parts damages.
Due to taper or the tubular construction of insulator, in high temperature electrostatic deduster running, high-temperature flue gas is in unordered turbulent condition herein all the time, compared to common electrostatic duster, molecular motion is more violent, and produces a large amount of eddy current, dust is made to have sufficient chance to contact inside insulator, if without ad hoc blow device, full-bodied dust will adhere to very soon, and destroys integral insulation performance.The operating electrostatic precipitator of current major part without automatic cleaning device, only relies on artificial to the dust stratification of insulator inner surface, and the long-term stability that cannot meet deduster is run, and easily causes voltage instability maybe can not reach technical requirement, affects dust removing effects.
Summary of the invention
For solving above Problems existing, the utility model provides a kind of high temperature electrostatic deduster insulator blow device, and its technical scheme taked is:
This device comprises blast pipe, high-temperature blower, tube connector and four TPU flexible pipes, it is characterized in that: blast pipe connects the air inlet of high-temperature blower by expansion joint, the left end of tube connector connects the air outlet of high-temperature blower, its right-hand member is divided into four arms, each arm inserts in the incubator of deduster, and connect corresponding TPU flexible pipe by copper joint, insulated porcelain sleeve is positioned at incubator inside, and its top is provided with capping, along having four equally distributed through holes in capping, each through hole internal pipeline is class helical form, and the right-hand member of each TPU flexible pipe inserts in corresponding through hole.
The utility model adopts the high temperature resistant and TPU pipe of insulation as the material of connecting porcelain bushings and external air source, the operation security of operation under guarantee high-pressure high-temperature environment; Source purge gas uses the exiting flue gas of high temperature electrostatic deduster, guarantees the clean as far as possible and high temperature of purging air, takes precautions against the insulator that issuable source of the gas pollutes and temperature decrease occurs and burst; Use high-temperature blower to provide cleaning power, continue to input air-flow in insulator; Inclined hole is opened in the capping of insulator, as purging wind inlet, and according to the concrete specification of insulator and the inclination size of Sizes design perforate, ensures the spirality Purge methods of air-flow, increase clean area, strengthen ash-removal effect.
The utility model structure is simple, and stable, Be very effective, can not only adapt to hot operation environment, operation steady in a long-term, and for high viscosity, the dust of high-hydroscopicity, effectively can prevent absorption.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As depicted in figs. 1 and 2, the upper end of blast pipe 1 connects the air inlet of high-temperature blower 3 by expansion joint 2, and its lower end connects the outlet of high temperature electrostatic deduster, and expansion joint 2 is for cushioning steel heat deformation under the condition of high temperature.The left end of tube connector 4 connects the air outlet of high-temperature blower 3, and its right-hand member is divided into four arms, and each arm inserts in the incubator 7 of deduster, and connects corresponding TPU flexible pipe 6, TPU flexible pipe 6 by copper joint 5 and adopt heatproof isolation material, can prevent electric leakage.It is inner that insulated porcelain sleeve 8 is positioned at incubator 7, and its top is provided with capping 9, the interior edge of capping 9 has four equally distributed through holes, each through hole internal pipeline is class helical form, make air-flow in insulated porcelain sleeve 8, form helical form to decline, clean along inwall, the right-hand member of each TPU flexible pipe 6 inserts in corresponding through hole.
The exiting flue gas of high temperature electrostatic deduster enters high-temperature blower 3 by blast pipe 1, enter tube connector 4 subsequently, in insulated porcelain sleeve 8, compressed air is carried finally by TPU flexible pipe 6, due to the lasting input of outer gas stream, form relative higher-pressure region by insulated porcelain sleeve 8 inside, reduce the probability that internal gas flow disorderly enters.
