Description

Electric precipitator with anti-dew insulator room

The utility model relates to a kind of, is mainly used in the supporting electric cleaner of cement plant dryer and raw mill.

The medium-sized and small enterprises of China's cement industry nearly all use widely different rotatable dryer and raw mill.But this class dryer and raw mill produce in when work institute and to contain the bigger waste gas of steam, and difficulty of governance is bigger, thereby most of producer all do not add processing and natural emptying, and both contaminated environment was lost a large amount of materials again.In order to address this problem, once there were some cement plants to adopt insulators to put inside or the tube-type esp of deduster air outlet, carry out the waste gas pollution control and treatment of dryer and raw mill, all obtain dust removing effects preferably.But the weak point of this electric cleaner, be that its insulator is directly exposed in the electric field that is full of dust and the very big deduster air port of temperature, resistive connection reveals poor performance, often cause the electric fault of electric leakage, creepage, short circuit, directly influence the operate as normal of electric cleaner because of the serious dewfall of insulator surface is moist.

The purpose of this utility model is to propose a kind of improved electric cleaner that the anti-dewing insulator chamber is arranged, and it can prevent effectively that insulator from producing dewfall, to improve the stability and the reliability of electric cleaner work.

The utility model is by plenum chamber, cylindrical shell, cathode line, conducting rod, insulator, the storage ash bucket, the cathode rapping motor is formed, an insulator chamber is arranged at the plenum chamber top, it is divided into two Room up and down by dividing plate, the cathode rapping motor is indoor at first of insulator chamber by four screw devices that are with spring, insulator is lifted on by screw rod that second is indoor, be connected perforation by several cylindrical shells between plenum chamber and the bucket, cathode line upper end in each cylindrical shell adopts bearing support to hang, the lower end connects with connecting rod, constitute cage type integral body, the conducting rod lower end is connected with cathode line, and high tension insulator sleeve pipe and dust cover that the plenum chamber top is passed in its upper end hang on the insulator lower end.High voltage source inserts conducting rod through the high pressure wall pipe, and the high tension insulator sleeve outer wall on dust cover top is provided with electric heater device.Insulator separates itself and waste gas in insulator chamber like this.Simultaneously, the porch that penetrates for conducting rod between plenum chamber and insulator chamber is provided with dust cover, this dust cover is actually a miniature electric cleaner, when containing wet dust on a small quantity and enter just by absorption, broken off the inboard unique creepage approach of high tension insulator sleeve pipe, thereby guaranteed that insulator surface can not produce the electric fault that causes because of dust pollution and dewfall.

The utility model has fundamentally solved the dewfall difficult problem of insulator surface owing to adopt insulator chamber and the frame mode of waste gas isolation.Simultaneously, its high voltage source is high-order layout, and high-tension cable is not subjected to exhaust emission yet, makes electrical system possess good working environment, has improved the reliability of complete machine work greatly.

Concrete structure of the present utility model is provided by the following drawings and embodiment.

Do further specifying of enforcement below in conjunction with accompanying drawing: the utility model has a plenum chamber (9), establish an insulator chamber (4) at its top, be separated into two Room up and down with dividing plate (13), last chamber dress cathode rapping motor (1), rapping power is by spring (2), screw rod (12), insulator (3), make cathode line (10) produce extensional vibration, improve the cathode ash-clearing effect greatly.Insulator (3) relies on screw rod (12) to be hung on that second is indoor; The plenum chamber top is provided with dust cover (7) for the porch that conducting rod (8) penetrates, a high tension insulator sleeve pipe (5) is established on its top, the tubular electric heater unit (6) of being furnished with automatic temperature-adjusting control at sleeve outer wall, guarantee that the inboard temperature of high-tension electricity insulator is higher than dew point, even there is the wet dust of containing to enter, also be unlikely to produce dewfall.The dust cover of bushing end opening adopts steel plate to roll, and forms miniature electric cleaner with the conducting rod (8) by its center, when a spot of dust is diffused into this cover, is accepted by dust cover, prevents to enter high tension insulator sleeve pipe inboard.Conducting rod (8) lower end is connected with cathode line (10), and the upper end passes the plenum chamber top and dust cover is suspended on the insulator lower end; High voltage source is connected with conducting rod through high pressure wall pipe (20) lead-in insulator is indoor by high-tension cable (21).

This electric cleaner is according to different working condition requirements, can adopt a plurality of cylindrical shells (11) to be used in combination, generally at least with 3 cylindrical shell combinations, present embodiment adopts 6 cylindrical shell combinations, after 6 cylindrical shell combinations, may make the air-flow skewness, the pipe disposal ability deficiency that makes, the pipe disposal ability surplus that has can cause total efficiency of dust collection to reduce; So the whirlwind current equalizer of being made up of the cylinder (16) of blast pipe (18), directing vane (12) and band commutator segment preferably is set in the storage ash bucket (19) of deduster, and 6 cylindrical shell circular arrangement match with it.When the high speed dust-laden exhaust gas enters the whirlwind current equalizer, portion produces whirlwind within it, band commutator segment cylinder is assigned to each cylindrical shell equably with the flue gas of outlet, carry out electrostatic precipitation, there is the cyclone dust removal effect current equalizer inside simultaneously, the dust concentration that has improved the efficient of complete machine dedusting and allowed to enter the mouth.Rigid female polar curve (10) in each cylindrical shell does not adopt up and down porcelain and hangs, and the upper end adopts supporting to add (23) to connect conducting rod and hang, can cathode line be rocked because of air-flow rises, guarantee the stability of dedusting work.What the plenum chamber top was provided with that three discharge pipes converge into an air outlet goes out wind apparatus (22), three discharge pipes are distributed on 120 ° the reticule, and the shaft centre line that makes airduct is on the bisector of two cylindrical shells, and symmetric arrays makes wind path length the same like this, resistance is identical, and it is even to help air-flow.In order to prevent dewfall in the cylindrical shell, the whole air path system of deduster cylindrical shell, ventilation shaft etc. should be provided with heat-insulation layer (24), and makes six cylindrical shells form an integral body from outward appearance.In order in time to remove anode (being cylindrical shell) dust stratification, an anode vibrating motor can be installed in per two cylindrical shells middle part.Access door (15) is used for regular maintenance and periodic inspection.
