Abstract
The invention relates to an insulation-box air-curtain shielding electrical dust remover, which comprises a support-insulator insulation box and a rotating-shaft insulation box which are supported on an electrical dust removal box, wherein a first wind pipe is arranged in the support-insulator insulation box and is communicated with the inner cavity of the electrical dust removal box through the inner cavity of a tapered insulating sleeve; and a second wind pipe is arranged on the rotating-shaft insulation box and is communicated with the inner cavity of the electrical dust removal box through the inner cavity of the rotating-shaft insulation box. Hot wind is blown to the connecting position with the electrical dust removal box by adopting the wind pipes to form an air curtain, so that process gas can not invade into an insulator chamber, and the surface of an insulator can not be polluted. The condition that the insulator is polluted to be damaged can be eliminated fundamentally, the occupied ratio of air curtain wind mixed in the process gas is smallest, the normal operation of the system is not influenced, the balance of gas pressure of the production system can not be damaged, and the stable production can be always protected.
Description
Technical field
The present invention relates to a kind of electric cleaner, is a kind of insulated case air curtain shielding electric cleaner specifically.
Background technology
Electric cleaner is to utilize high voltage electric field to separate the equipment of higher suspension dust in gas.Send a negative electrode very of high pressure, dust collector pole ground connection, the dust that will be adsorbed on the electrode through rapping shakes, and from ash bucket, discharges.Dedusting both at home and abroad connects the electric cleaner fault that the personage generally acknowledges has three, and one is the cathode line breaking releasing, causes anode and cathode to be communicated with and send and do not power on; The 2nd, the beater mouth falls down and falls into ash bucket and block ash exhauster; The 3rd, the cathode support insulator is polluted, failure of insulation and can't send high-tension electricity.Replace the fine wire lead that negative electrode is not broken with the rigid female polar curve, can not fall hammer with whole hammer replacement burst hammer, and failure of insulation takes place the most easily, the most difficult again thoroughly solution.The cathode support insulator is the supporting member that supports cathod system, adopts the taper insulating sleeve usually; Insulated connecting piece in the cathode rapping mechanism is to transmit moment of torsion, selects the insulation axle for use.During the electric cleaner operation, the surface of insulator all contacts with process gas, if condensations such as the steam in the process gas, acid are adhered on the insulator; Its surface insulation promptly lost efficacy, and formed surface leakage, and electric field send and do not power on when serious; The heat of electric leakage burns out insulator and breaks or rupture; Some particle also can cause insulation breakdown attached to insulator surface in the process gas, and traditional processing method is labor cleaning or blowing cleaning, fails to tackle the problem at its root.
Summary of the invention
In order to solve deficiency of the prior art, the invention provides a kind of simple in structurely, compact, insulator surface is pollution-free, the insulated case air curtain shielding electric cleaner that electric cleaner is stable.
The technical scheme that the present invention adopts is: a kind of insulated case air curtain shielding electric cleaner; Comprise electric precipitation case, supporting insulator insulated case and rotating shaft insulated case; The supporting insulator insulated case all is connected on the electric precipitation case with insulation axle insulated case; Be provided with the taper insulating sleeve in the supporting insulator insulated case, the taper insulating sleeve is provided with the rotating shaft insulator through suspension rod support and connection electric precipitation case cathod system in the insulation axle insulated case; Rotating shaft insulator one end connects motor driving shaft, and the other end connects rapping shaft; It is characterized in that being provided with first airduct in the said supporting insulator insulated case, first airduct is communicated with the electric precipitation box cavity through taper insulating sleeve inner chamber; Said insulation axle insulated case is provided with second airduct, and second airduct is communicated with the electric precipitation box cavity through insulation axle insulated case inner chamber.
Said taper insulating sleeve lower port is communicated with the electric precipitation case, and taper insulating sleeve port is provided with casting coping, and hang on casting coping the suspension rod upper end, and the suspension rod lower end penetrates the electric precipitation case and connects cathod system.
Said first airduct passes casting coping through first jet pipe and is communicated with taper insulating sleeve inner chamber.
Taper insulating sleeve lower port is socketed with protection metal pipe, and protection metal pipe is communicated with taper insulating sleeve inner chamber and electric precipitation box cavity.
20-30 ° of said first jet pipe and suspension rod angle.
Said rapping shaft is supported between insulation axle insulated case and electric precipitation case through quartz plate, and airduct is communicated with the electric precipitation box cavity through insulation axle insulated case, quartz plate successively.
Said second airduct is communicated with insulation axle insulated case inner chamber through second jet pipe.
30-60 ° of said second jet pipe and rotating shaft insulator angle.
The taper insulating sleeve is installed in the supporting insulator insulated case on electric precipitation case top; Cathod system is hung on the casting coping of taper insulating sleeve upper end through suspension rod, and suspension rod, loam cake all are with high-tension electricity during operation, the base plate of sleeve pipe lower end and protection tube ground connection; First airduct is on casting coping top; First jet pipe stretches in the casting coping, and the hot blast that sprays during air feed forms air curtain in taper insulating sleeve lower surface, blocks process gas by getting in the electric precipitation case in the taper insulating sleeve; Protection metal pipe further stops process gas directly upwards to wash away, and makes the effect of air curtain more obvious.The first jet pipe angle, jet size and jet amount decide according to the pressure of device interior process gas.The angle decision of first jet pipe forms the position of air curtain, generally selects 20～30 °, nozzle hole diameter 2～3mm, and jet amount is pressed the pressure of process gas and is regulated wind regime pressure 3000～3500Pa.
Insulation axle insulated case outer end, left side and reductor link, and are driven by motor-driven beam warp rotating shaft insulator and stretch into the rapping shaft in the electric precipitation case.Second airduct warp, second jet pipe blows to insulation axle insulated case and electric precipitation case junction with hot blast, around rapping shaft, forms air curtain, plays shielding action jointly with the quartz plate that supports rapping shaft, and the process gas in the electric precipitation case is kept off outside insulation axle insulated case.Rapping shaft rotates during operation, and the air curtain around the moving link does not hinder the motion of member, has played protective effect simultaneously again.Second airduct and second jet pipe are installed in the middle part of insulated case.The angle that jet pipe inserts insulated case is 40～50 °, nozzle hole diameter 2～3mm, wind regime pressure 3000～3500Pa.
The present invention adopts the contaminated structure of avoiding insulating, and on supporting insulator insulated case, insulation axle insulated case, installs airduct additional, blows to hot blast with the connection of electric precipitation case from certain angle and forms air curtain; The pressure of a little higher than process gas of pressure of air curtain; Make process gas can not invade insulator chamber, insulator surface just can not polluted, and can fundamentally eliminate insulator and occur because of contaminated situation about destroying; It is minimum finally to sneak into the shared ratio of air curtain wind in the process gas; Do not influence the normal operation of system, can not destroy the balance of production system gas pressure, can protect the steady of production all the time.
