Description

Wet type high voltagehigh frequency electrostatic precipitator
Technical field
The present invention relates to a kind of deduster, particularly industrial electrostatic precipitator.
Background technology
In recent years, electrostatic precipitator proportion shared in industrial fumes purification is increasing, and dust removing effects are also increasingly Height, effect of the electrostatic precipitator in environment protection treating is also increasing.Electrostatic precipitator mainly divides dry electrostatic by purge mode Deduster and wet scrubber, its general principle and the course of work, are roughly divided into charged, collection and deashing three phases.Wet type Electrostatic precipitation is identical with structure with dry type static dust general principles, and its main distinction is the difference of purge mode.Dry type is quiet Electric cleaner is by the way of vibration dust-cleaning, and wet cottrell uses the mode of current cleaning.
Wet cottrell is a kind of efficient deduster, and its purge mode and temperature in use determine that it is efficient special Point, under normal circumstances, its outlet drain can reach below 10mg/Nm3, or even below 5mg/Nm3.However, existing wet type The dust removing effects of electrostatic precipitator are undesirable, had no way effective place to go for some phosphorus sulfur materials, while working a period of time Afterwards, it is necessary to be rinsed to electrode, and all it is that, by being manually sprayed, not only efficiency is low in the prior art, and not Safety, the top that workman generally requires to climb to deduster carries out operation.
The content of the invention
The technical problem to be solved in the present invention is:A kind of good dedusting effect and wet static dedusting easy to clean are provided Device.
The present invention solve its technical problem solution be:Wet type high voltagehigh frequency electrostatic precipitator, includes tower body, institute The front end for stating tower body is connected with atomising device, rear end provided with air exhausting device, and the tower body is interior to be provided with many discharge electrodes and receiving electrode, The discharge electrode is socketed in receiving electrode, and the periphery of the tower body is provided with terminals, the terminals and discharge electrode/receiving electrode Electrical connection, also includes power cabinet with being sprayed device, the power cabinet and includes high-frequency and high-voltage power supply group, the power supply group Electrically connected with discharge electrode with receiving electrode;The work of the high-frequency and high-voltage power supply group is that frequency is 18KHz--32KHz, operating voltage For 20K--60KV;Described to be sprayed the top that device is arranged on tower body, the spray irrigation device includes multiple vortex sprays Head.
As the further improvement of above-mentioned technical proposal, the bottom of the tower body is provided with flue-dust retainer, and the flue-dust retainer goes out Mouth is connected with purifier.
As the further improvement of above-mentioned technical proposal, the spray irrigation device also include storage tank, high-pressure pump with Connecting tube, the connecting tube is connected with cyclone showerhead, and the storage tank includes refluxing opening, and the refluxing opening connects with purifier It is logical.
As the further improvement of above-mentioned technical proposal, the purifier includes filter screen, precipitation pond and activity Charcoal absorption bag, the charcoal absorption bag is in precipitation pond, opening of the filter screen located at precipitation pond.
The beneficial effects of the invention are as follows:By the present invention in that power supply be three-phase AC-DC overlaying power, frequency 18KHz--32KHz, voltage 20K--60KV, can produce larger streamer, have to dust, sulfur dioxide, nitrogen oxides and go more by force Except rate., can effective extension device use time and tower body top is automatically rinsed provided with device is sprayed to laying dust And reduce the labor intensity of workman.
Brief description of the drawings
Technical scheme in order to illustrate more clearly the embodiments of the present invention, below will be to that will make needed for embodiment description Accompanying drawing is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present invention, rather than is all implemented Example, those skilled in the art on the premise of not paying creative work, can also obtain other designs according to these accompanying drawings Scheme and accompanying drawing.
Fig. 1 is the structural representation of the present invention.
Embodiment
The technique effect of the design of the present invention, concrete structure and generation is carried out below with reference to embodiment and accompanying drawing clear Chu, it is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair Bright a part of embodiment, rather than whole embodiments, based on embodiments of the invention, those skilled in the art is not paying The other embodiment obtained on the premise of creative work, belongs to the scope of protection of the invention.In addition, be previously mentioned in text All connection/annexations, not singly refer to component and directly connect, and refer to be added deduct by adding according to specific implementation situation Few couple auxiliary, to constitute more excellent draw bail.Each technical characteristic in the invention, in not conflicting conflict Under the premise of can be with combination of interactions.
Reference picture 1, wet type high voltagehigh frequency electrostatic precipitator includes tower body 1, and the front end of the tower body 1 is connected with atomization Device, rear end are provided with provided with many discharge electrodes 2 and receiving electrode 3 in air exhausting device, the tower body 1, and the discharge electrode 2 is socketed in product In dirt pole 3, the periphery of the tower body 1 is provided with terminals, and the terminals are electrically connected with the receiving electrode 3 of discharge electrode 2/, also included There is power cabinet 4 to include high-frequency and high-voltage power supply group with being sprayed device 5, the power cabinet 4, the power supply group is with discharge electrode 2 Electrically connected with receiving electrode 3;The work of the high-frequency and high-voltage power supply group is that frequency is that 18KHz--32KHz, operating voltage are 20K-- 60KV;Described to be sprayed the top that device 5 is arranged on tower body 1, the spray irrigation device 5 includes multiple vortex shower nozzles 51.When work, the positive pole of power supply is connected on Electrical Discharge Machine 2, and negative pole is turned on receiving electrode 3, and receiving electrode is just when energization Electrostatic can be taken;Dust first passes through atomising device in the presence of air exhausting device so that the globule on dust band, after then getting wet Dust is adsorbed when passing through tower body by powered receiving electrode, is sticked on receiving electrode.Described receiving electrode can be cylinder Shape, facilitates the deposition of dust.Then, can be to dust, sulfur dioxide, nitrogen oxides all because power supply uses high-frequency and high-voltage There is stronger clearance, clean-up effect is more preferable.Also when laying dust reaches it is a certain amount of when, rushed by spray on tower body Cleaning device is sprayed to receiving electrode, is eliminated artificial operation, is improved operating efficiency.And because spray equipment is long-term In dust, relatively easily blocked by laying dust, therefore, present invention employs cyclone showerhead, the exit passageway of shower nozzle is one Individual swirling, the blocking for the dust being effectively prevented from.
