Abstract
The utility model provides a wet-electrostatic precipitator, which comprises an outer shell, a front cover and a rear cover, a high volatge electroplax, a polarization cavity and electrode plates. The front cover is provided with an air inlet mouth and a high voltage electrode, the electrode plates are arranged in a mixed flow chamber, the surfaces of the electrode plates are blankets that are pasted with liquid or cover layers with liquid, the rear cover has air discharge holes, and the side wall of the front end part of the outer shell is provided with an air inlet fan to blow in clean air. The polarization cavity has a number of metal wires and metal needles, the electrode plates are parallel square plates, round plates or coaxial cylinder plates, the air inlet mouth is connected with waste gas. Because the electrode plates are covered with blanket covers with liquid, charged particles lose charges and adhere to the electrode plates when contacting, so that dedusting efficiency is enhanced. The utility model is used in dedusting process of diesel engine exhaust and various kiln and furnace waste gas.
Description
The utility model relates to a kind of flue dust dirt retracting device, particularly a kind of wet cottrell that the adhesion of solid is captured by electrostatic attraction and liquid.
The electrostatic precipitator of using is a kind of dry-type working device that does not contain liquid now, is used for producing in the industrial enterprise of smoke contamination more, and purpose is the solid particle that reclaims in the flue dust.Because electrostatic precipitator can not be adsorbed soot dust granule effectively; this be because particle near and when colliding the collecting board electrode; can be with going up the electric charge identical or losing electric charge with the collecting board electrode; because same sex electric charge repels each other; soot dust granule can fly away from the collecting board electrode because of the effect of repulsive force, makes that the dust removing effects of this dry electrostatic cleaner is undesirable.
The novel purpose of this reality is to propose a kind of liquid adhesive attraction that utilizes soot dust granule add collecting, with eliminate grit near or the influence that repels each other because of band same sex electric charge when colliding the collecting board electrode, the raising efficiency of dust collection overcomes the deficiencies in the prior art.
This wet cottrell that the utility model proposed, it has shell, front and rear cover, high-field electrode, polarization chamber and battery lead plate, air inlet is arranged on the drive end bearing bracket, it is characterized in that adorning on the drive end bearing bracket high-field electrode, it is indoor that battery lead plate is contained in the mixed flow that shell surrounds, electrode plate surface has woollen blanket or carrying liqs jacket layer or the liquid film that is adhering to liquid, has steam vent on the rear end cap.
The air inlet blower fan is housed on the sidewall of shell fore-end.
The air inlet blower fan is two of symmetry, and shell and air inlet are circular or square.
Polarization is equipped with wire or the metal needle that 30-5000 root diameter is the 0.001-1 millimeter in the chamber.
Battery lead plate is 3-100 tabular or at least 2 idiostatic electrodes of coaxial line tubular, and is gapped between battery lead plate.
Battery lead plate can be a coaxial plectane group parallel to each other, rotary, and every plate electrode plate is provided with a corresponding pole plate brush.
The leading portion of air inlet is insulating properties materials such as plastics, and back segment is a metal material.
The leading portion inwall of shell has metal inner lining.
The liquid that the battery lead plate blanket puts is oil, water or liquid, aqueous.
The course of work of the present utility model is roughly as follows:
Cleaned air in the atmosphere blasts the polarization chamber by the blower fan on the sidewall, and is charged through contacting with high-pressure metal pin or wire; The dusty gas that has grit is introduced the mixed flow chamber from air inlet, and forms air-flow naturally, clean gas charged in the polarization chamber is sucked with it mix, and makes solid body particle charged; The battery lead plate gap that mist enters flue dust collecting contacts with pole plate, because battery lead plate is ground connection, charged particle will knock the blanket that pole plate is adhered to liquid and put, and gas is then discharged from the venthole of rear end cap.Thereby play Purge gas, remove the effect of grit.
The utility model since on battery lead plate suit contain the blanket cover of liquid, make charged particle contact with battery lead plate lose electric charge in, in time adhered to firmly, thereby the problem of having avoided charged particle to catch and escape has improved the efficient of dedusting greatly.The utility model can be widely used in the tails dedusting of common vehicle, particularly Diesel engine, purifies air, and reduces atmosphere pollution.In addition, there is the dust removing effects of the equipment that waste gas and flue dust discharge also more satisfactory to common smoke evacuation boiler, brick and tile kiln etc.
Further specify the utility model with accompanying drawing and example below.
Accompanying drawing 1 is front view of the present utility model (just analysing and observe).
Accompanying drawing 2 is left views.
Accompanying drawing 3 is right views.
Accompanying drawing 4 is shell and air inlet front views (just analysing and observe) when being square.
Accompanying drawing 5 is left views of Fig. 4.
Accompanying drawing 6 is vertical views (part) of Fig. 4.
Shown in Fig. 1-6.The leading portion of air inlet (1) is a plastic tube, and back segment is metal pipes (6) such as copper, stainless steel, and this section is through the major part in hyperpolarization chamber, near mixed flow chamber (9).Shell (8), drive end bearing bracket (3) and rear end cap (11) etc. are made with insulating materials such as plastics, potteries usually with the outside parts that contact, and shell is divided into two parts, and preceding sub-fraction is polarization chamber (4), and the back major part is the mixed flow chamber.Polarization is provided with high-field electrode (2) and wire that links to each other with electrode or metal needle in the chamber.Adorn the blower fan (5) of two symmetries on the sidewall of chamber, mix with flue dust gas in order in the polarization chamber, to blast cleaned air.The leading portion of mixed flow chamber is provided with metal inner lining (7), and the metal segments of it and air inlet all is with high-pressure electrostatic, in order to improve the charged efficient of gas and grit.The back segment of mixed flow chamber installing battery lead plate (10), battery lead plate is some metallic plates that are fixed on the rear end cap (11), they or flat board or coaxial line cylinder plate parallel to each other.Have some ventholes (12) on the rear end cap, form hole pattern, discharge for purified gas.
Metal needle, the battery lead plate of installing 0.08 millimeter of 300 diameter in the polarization chamber are four cylinders of coaxial line, 0.3 meter of tube length, power of fan are each 300 watts, all the other structures and parameter are as mentioned above, be used for receiving when handling diesel motor exhaust, substantially can not see black color from the gas that venthole is discharged, after tested, the discharge quality index has reached the requirement of environmental administration fully.
When being used for handling the big waste gas of fume amount, the grit that traps on the battery lead plate is a lot, cleaning pole plate woollen blanket by periodic is not enough, at this moment, must use the constructional device shown in Fig. 4-6, shell, air inlet are all done squarely, the indoor pole plate of mixed flow is one group of coaxial plectane parallel to each other, rotate (13) slowly around the shaft under motor (15) drives, still be set with woollen blanket on the pole plate, oil-containing or other liquid on the blanket, the grit that traps are brought to mixed flow when outdoor, draw together down by pole plate brush (14), so continuously work.Even also available water under high pressure bundle washes away institute's control of dust grain, and one improves and draws together brush efficient, and two can be in passing to replenishing adhering liquid on the woollen blanket.Certainly, when pole plate adopted rotary plectane, the space of mixed flow chamber was amid a sharp increase, a cover also will be set with on the battery lead plate cover, prevents that flue dust from leaking.
This electrostatic precipitator has improved more than 30% than existing deduster the arresting efficiency of grit, welcome by the trier.
