Abstract
The utility model relates to an electric precipitator for shielding a supporting insulator insulation box by adopting an air curtain. The electric precipitator is formed by connecting a supporting insulator insulation box on an electric precipitation box in a supported manner, wherein a conical insulating sleeve is arranged inside the supporting insulator insulation box and is connected with a cathode system of the electric precipitation box by a suspender in a supported manner. The electric precipitator also comprises an air pipe which is communicated with the inner cavity of the electric precipitation box via the inner cavity of the conical insulating sleeve. The electric precipitator has the following beneficial effects that: the electric precipitator adopts the structure preventing the insulator from being polluted; the air pipe is additionally installed in the supporting insulator insulation box, hot air is blown to the lower end face, contacted with the electric precipitation box, of the conical insulating sleeve from a certain angle to form an air curtain and the pressure of the air curtain is slightly higher than that of the process gas so that the process gas can not intrude into the insulator chamber and the surface of the insulator can not be polluted, thus radically preventing the insulator from being destroyed due to pollution; and the air curtain air finally mixed into the process gas is less, thus not affecting normal operation of the system, not destroying the balance of gas pressure of the production system and always protecting stabilization of production.
Description
Technical field
The utility model relates to a kind of electric cleaner, is a kind of supporting insulator 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.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, it is a kind of simple in structure, compact that the utility model provides, supporting insulator surface no-pollution, the supporting insulator insulated case air curtain shielding electric cleaner that electric cleaner is stable.
The technical scheme that the utility model adopts is: a kind of supporting insulator insulated case air curtain shielding electric cleaner; The support and connection of supporting insulator insulated case are on the electric precipitation case; Be provided with the taper insulating sleeve in the supporting insulator insulated case; The taper insulating sleeve is characterized in that also comprising airduct through suspension rod support and connection electric precipitation case cathod system, and airduct is communicated with the electric precipitation box cavity through taper insulating sleeve 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 airduct passes casting coping through 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 jet pipe and suspension rod 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; Airduct is on casting coping top; 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.Jet pipe angle, jet size and jet amount decide according to the pressure of device interior process gas.The angle decision of 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.
The utility model adopts the contaminated structure of avoiding insulating, and in the supporting insulator insulated case, installs airduct additional, blows to the lower surface formation air curtain that the taper insulating sleeve contacts with the electric precipitation case to hot blast from certain angle; 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.
