Description

Wet electrostatic filter lampblack absorber

The utility model relates to the high-voltage static flue gas removing technical field, particularly a kind of wet electrostatic filter lampblack absorber.

The electric field structure of existing a kind of high-pressure electrostatic filter lampblack absorber is such: the anode of high-voltage electrostatic field is made up of one group of hexagonal honey comb structure, the negative electrode of a needle ball structure is equipped with in the centre of each honeycomb, all cathode needles all are fixed on the cathode carrier of anode top, utilize the high voltage electric field that forms between cathode needle and the hexagonal honeycomb to come the filtering oil smoke.The shortcoming of this structure is that the rigidity of anode is relatively poor, the position of each honeycomb, size and shape have bigger error during making, thereby the uniformity of electric field is reduced, and cause the electric field at some positions stronger, the electric field at other positions a little less than, thereby influenced the overall oil strain cigarette effect of equipment.After static filter lampblack absorber uses certain hour, do not note the cleaning of electric field or clean not thoroughly, will influence its oil strain cigarette effect, even lose efficacy as if the user.The maintenance or the cleaning of lampblack absorber for convenience must remove cleanings, maintenance or replacing to the anode of equipment, for the hexagonal honeycomb structure, as if whole electric field is removed, then too greatly, too heavy; If be divided into several groups, then the rigidity of every group of honeycomb structure can be poorer, is easy to damage in dismounting and cleaning process.

The purpose of this utility model is to provide a kind of wet electrostatic filter lampblack absorber, and it not only has anode packet configuration for convenience detach, and can also clean automatically electric field structure when work, keeps the cleaning of electric field.

The purpose of this utility model is achieved in that a kind of wet electrostatic filter lampblack absorber, comprise loam cake, casing, oil separating plate, high-pressure electric control case and be contained in the interior high-voltage electrostatic field of casing, last tops has a suction opeing at least, the anode of described high-voltage electrostatic field is that the 2-6 group is columnar structured, in each cylindrical metal pipe central authorities the negative electrode of an acicular texture is installed; Described electric field below is for being provided with the spray chamber of an atomising device at least.

Described every group of anode is made up of one group of cylindrical metal pipe that is close to mutually and the forming metal plate that is fixed on this group cylindrical metal pipe upper and lower end.Described negative electrode is made up of cathode carrier and cathode needle, and cathode needle one end is fixed on the cathode carrier, and cathode carrier is fixed on the casing by insulator.To organize anode more and pack in the casing, one group of compressing tablet is housed on the skeleton in casing, compressing tablet one end is pressed on each group anode in the casing.

As long as unclamp the compressing tablet of respective anode group, and turn over certain angle, so long disassemble cleaning, maintenance or replacing easily downwards just organize anode to this.Many group anode constructions make every group of anode construction have rigidity preferably.

The spray chamber that is positioned at wet electrostatic filter lampblack absorber bottom is equipped with one or more atomising devices, it is supplied water by the water supply installation of peripheral hardware, the water smoke that atomising device produces is followed air-flow and is risen in the interior high voltage electric field of casing, constantly moistening and clean the anode and the negative electrode of electric field, thus the cleaning that guarantees electric field is clean.The existence of water smoke also has such effect: can reduce the temperature that enters the electric field flue gas, improve the stability and the oil strain effect of field operation; Can also intercept the cooking stove naked light and enter the smoking system, prevent the generation of flue fire.

Advantage of the present utility model is electric field anode construction good rigidly, mounting or dismounting conveniently; Can produce water smoke during work automatically and clean electric field, guarantee that it works effectively reliably.

By following embodiment the utility model is further elaborated.

Referring to Fig. 1-shown in Figure 4, a kind of wet electrostatic filter of the utility model lampblack absorber is made up of loam cake 2, casing 3, high-pressure electric control case 1, spray chamber 4 and the high voltage electric fields that are contained in the casing 3.Loam cake 2 tops have two suction opeings 7, and spray chamber 4 is equipped with an atomising device 6.Casing 3 internal electric field anodes 13 are divided into four groups, and each group anode is made up of several cylindrical metal pipes that are close to 11 and the forming metal plate 12 that is fixed on these cylindrical metal pipe 11 upper and lower ends.Four groups of anodes are packed in the casing 3, a collection of compressing tablet 15 is housed on the skeleton 16 in casing 3, compressing tablet 15 1 ends are fixed on the skeleton 16 with screw 14, and compressing tablet 15 other ends are pressed on each group anode 13 in the casing 3.Negative electrode 8 is made up of cathode carrier 9 and some cathode needles 10 fixed thereon.Cathode carrier 9 is fixed on the casing 3 by insulator.Each root cathode needle 10 is positioned at each cylindrical metal pipe 11 central authorities, forms a high voltage electric field.The spray chamber 4 that is positioned at filter lampblack absorber bottom is equipped with an atomising device 6, by the water supply installation water supply of peripheral hardware.The water smoke that atomising device 6 produces is followed air-flow and is risen in the high voltage electric field, constantly cleans electric field.Oil separating plate 5 the dripping in order to the obstruct spray chamber that one group of grooved steel disc is made also is housed in spray chamber 4 bottoms.

The course of work of this wet electrostatic filter lampblack absorber is such: flue gas passes oil separating plate 5 and enters spray chamber 4, enters the high-voltage electrostatic field of 13KV-25KV then, after the electric field filtering, by loam cake 2 by outside its two pairs of suction opeings, 7 discharge machines.
